  1. Fascinating post Nick. I always enjoy reading about what you have been tinkering with and this latest project does not disappoint! Hope you get to enjoy driving the car a little now. I feel your pain about moving as we have just done the same. I ended up having to take out a new unit to clear out my garage whilst we moved and low and behold, once bad back and 4 months later and all my stuff is still in storage. Slowly getting the garage to where I need it to be but lots still to do before the weather turns. I can Ill afford 2 storage units so time to get posterior into forward drive!
  2. I believe that it is a GL4 spec oil. I have some 1 Litre bottles available at the moment priced £14. I have tidied the contents of this thread up and moved it into the Members Only area, under Parts and Suppliers. I have locked this thread for commenting and will delete in a while. New Thread is here (for members only) -
  3. I knew I had seen this before. Great find from 10 years ago! I’ll do some editing when I’m at my desktop and join this info up. Cheers Gary. I will also move it into the right section now it has got going.
  4. We had a place years ago where all the useful GM part numbers were saved so I thought we would resurrect this. If you have any part Numbers to add, please post them up and I will edit them down into a single list - to keep it easy to browse. ===================================================================================================== ENGINE & GEARBOX Getrag Transmission Oil - SAE 75W / 85W - Part No 93165290 CIH Oil Filter (1.9 / 2.0 / 2.4) - 93156958 CIH Sump Gasket kit - 08983127 CIH Rocker Cover Gasket - 90002406 1.8 Cam Cover Gasket - 90354545 ===================================================================================================== CHASSIS Opel Manta B Upper Ball Joint - 90093763 =====================================================================================================
  5. One of the Security Blokes at Billing had a GT/E a few years back.....think his was white though. I wonder if he is still about - Just thinking that Riverside would be nearby for him. I was up there at Lunchtime yesterday but no so luck!
  6. Well if you could pull something together we can make sure that you get a copy of the magazine, that’s no problem at all.
  7. Ahhh....that was the infamous GUF! Excellent. Keep up the good work. Have you thought about putting an article together for the mag? It would make an interesting read and you know more about the Centaurs than the rest of us put together!
  8. I've been watching this thread with interest - I love to see these database coming together of the rare models. I was having a look through some old Billing Photos earlier this week and this White convertible cropped up for a few years running - MPL 1P. It has Centaur Badges on and according to the DVLA, was registered as a White Vauxhall Cavalier on 26th March 1980 - so the 4 slot front panel looks to be a later addition, like the Cheque Recaro interior and twin headlamps. I did have a quick skim through your list and I couldn't see this one mentioned.....the registration date and style of conversion would suggest that it is an original Centaur - at least I think! Here are a couple of pictures from the Concours at Billing in July 2004:
  9. Hi Steve and welcome to the OMOC Forum and Club site. I have dropped Steve a quick message and told him about your post. He is a regular visitor in these parts, so I expect you will hear from him in due course. I hope you find the site useful and decide to join the club, where you will be able to access the whole site including the recent for sale ads and a wealth of technical information. Regards, Paul.
  10. Hi Roemer, Welcome to the forum. The Louvres for the Manta are quite hard to find now. The ones we had available in the UK were manufactured by a company called Autoplas. They also did side louvres for the rear quarter glass windows. I had some fitted to my B Series when I bought it but they didn’t last long before I got rid of them. You can sometimes find them on eBay.
  11. You don’t see these come up for sale that often. In fact I don’t think I ever have ! Look good in a Manta with a 24v https://m.ebay.de/itm/Opel-Lotus-Omega-6-Gang-ZF-Getriebe-mit-Glocke-C36GET-24V-Irmscher-C30SE-CIH/183181765912?hash=item2aa67bed18:g:eBYAAOSwAL9UgdDr
  12. Ok. Thanks for your constructive input, as ever. I think I can speak for the majority of forum users that think you are, unfortunately, a bit of a troll. Sorry but we can’t tolerate that so you are bannished from the kingdom. Bye bye. For those of you that are interested, I looked for TRW TRANSPORTATION ELECTRONICS on Companies House and the company was wound up in 2004. Some people are surely just out to try and rub everyone up the wrong way. This is one troll that was not worth feeding any more.
  13. Philip, I don't really know what has annoyed you this time, so I'm not even going to expend too much energy replying to this post. I can say that the OMOC is a very welcoming club and we encourage members with all sorts of abilities, gender, geographical location and budget. What we don't tolerate however is rudeness and personal insults. This is not the first time I have had to speak to you about this sort of outburst. In fact, I think as a group of moderators and club officials, we have probably spoken about you as a forum user more than we have any other user in the last 2 years. You are, what I would call "High Maintenance". So - I would welcome an apology to the good people that put time and effort into keeping the club running. If this doesn't happen by the end of the weekend, you will be banned from the forum and your IP address blocked. You are more than welcome to go ahead and start up a new Manta club. Others (with far greater ability and budget than you) have tried it in the past and failed miserably. I predict that you probably wouldn't even be bothered to get it started but if you do - good luck to you. It will undoubtedly fail. You have until the end of the weekend to offer your humble apologies as a reply on this thread. If that is not forthcoming......its bye bye I'm afraid.
  14. Its the Crankshaft Rod and Pistons that are the problem with this engine. As you say, the block is basically the same old CIH block, although the Fronty version will have the 2.4 casting mark. IF rebuilding, it is probably worth looking into replacement rods and pistons, the VX design was pretty terrible.
  15. 104,000 miles and running badly. Sounds like it probably needs a bottom end rebuild so I wouldn't take this on lightly!
  16. Hi, The part number you need is 90194095 (or Opel part 658096). I have had a quick look in the usual places I find stuff abroad and I cant find any in stock. So, I guess your next choice is to have a look at a decent second hand one over here in the UK. I think the part was used an several Vx/Opel models in the early 80's so you could try looking for a Dipstick from a Petrol Engined Vauxhall Nova (probably the 1.2) or some of the Astra Mk1 or Mk2 models. I just found a second hand Nova one on eBay that looks like it may be similar. You could always remove the rubber bung and fit it to your existing oil level stick. There are a few NOS Astra ones on ebay that have the wrong size dipstick but probably have the right sized rubber bung, so another option I guess.
  17. It looks as though OCP have them in stock Steve http://www.opel-classicparts.de/blechteile-kotflugel/halter.html €5.71 inc VAT For info, if you are looking around: Opel Part 1180210, GM Part Number 02867957
  18. Awesome pics. Brings back some memories of shows every weekend and lots of camping.
  19. When the Opel Manta was launched in 1970, the world was a much simpler place. Fashion and Style - This was a decade when men wore stylish leatherette or Faux Suede and as far as colours were concerned, modern science had discovered a way of imitating the distinctive colour only usually seen when very young calves have an upset tummy. Panache - With every Manta ordered from your main Opel dealership came a guide on how to wear your Leatherette sports jacket over your shoulder, in fact in 1972 a Common Market directive made this compulsory for both men and women. Sex Appeal- Way back in 1970, sexism hadn't been invented and it was important that both men and women were the target of the Opel press machine. In fact it was very important that women realised that they could climb onto the bonnet of their husbands new Manta to perform those simple household chores like cleaning the windows or repairing the roof of the garden shed. Forward Thinking - A little known fact was back in the 1970's due to the power shortages and coal miners strikes, every new car owner was presented with a pair of white nylon slacks for use if they needed to recharge the car battery. 5 minutes of country dancing would produce enough electricity to fully charge a 55Amp hour battery. Environmentally Aware - Even as far back as the early 1970's, Opel recognised the need to preserve wildlife. With every purchase of a new Opel in 1972, the proud new owner was able to choose from a Great Dane for S denoted models, A Black Panther for SR models and African Elephant for all range topping GSI models. It surely must go without saying that naturally, none of this is true but the 70's sure were the most awesome decade!
  20. There have been a few books printed that feature the Manta. Naturally, some of the best ones are from Germany but there are several english language books that are worth picking up, if you can find them. Occasionally, we do find surplus copies of some of these books and will keep a small supply of them in the club shop - click here to visit the shop.

In 1981 the range was revitalised for the last time and a new engine option added. The 1.8 litre LET (Low end torque) Over head Cam engine was offered initially in the new Manta GTJ and Berlinetta. The exisiting 2.0 litre, which now included Bosch Fuel injection, made a return later in 1982 in the form of the GT/E. Several bodywork changes were made, with integral deep front spoiler and Rear spoilers on both the Hatchback and Coupe models. All traces of chrome had now dissappeared to bring the Manta in line with the 'clean' trend of the eighties. The new model featured many mechanical enhancements, which made the Manta a market leader in certain areas. A 5 speed gearbox was offered as standard on UK models and the level of instrumentation was increased to give every model an oil pressure gauge and volt meter. The ignition was now electronic on all models, helping to increase the specified service interval considerably. Style and Panache The facelifted Manta still owed much of its running gear to the more mainstream models, such as the Opel Ascona, (or the Vauxhall Cavalier in the UK), but the new styling components made the car look much more 'modern'. The colour -keyed wrap around bumpers, front and rear spoilers and sports wheels gave the car a new look. The addition of tinted glass and a front windscreen with a graduated 'shadeband' also echoed the styling trends of the day. The front nose cone now sported 4 small slots, as opposed to the 2 larger ones of the preceeding model. This helped to improve cooling efficiency and also made the car an imposing sight in your rear view mirror ! In all the Manta had come of age and was considered by many, to be at the forefront of Coupe design and technology. The new Model now had an astonishingly low drag coefficient. Model Drag Coeffiecient (Cd) Coupe 0.36 Hatchback 0.37 A Gripping Performer Manta roadholding and overall handling precision are sharp and responsive. A finely tuned coil and spring suspension set up, incorporating anti-roll bars, strikes the perfect balance between comfort and grip, a balance that most manufacturers seem to have forgotten how to acheive nowadays. Sensitive and accurate rack and pinon steering has just the right amount of feel to keep you informed of road wheel behaviour. Many leasons learnt running the successful Manta 400 International Rally car, were put into the design of the road car styling and roadholding ability. High Performer With 2 brand new engine options and the styling enhancements, the new Opel Manta had the performance to match its low sleek lines. Both options offered very respectable performance in its day. The 1.8 litre GT developed 90% of its engine torque at just 2000 revs, utilising a clever cross flow cylinder head design. The flagship GT/E symbolised Manta power and pace with a respectable 0-60 time of just 8.5 seconds. Several tuned varints were also available including the i200 and i240. These were made by special order from Irmscher UK, based in Walsall. Opel Sport Cloth trim came as a standard fitment along with Manta 400 Halogen quad Headlamps and deep air spoiler at the rear. Other options that were offered were Limited Slip Differential, Big Valve Head and uprated suspension. The Manta had the option for many different levels of performance Model Capacity (cc) Compression ratio BHP @ rpm Torque (lb/ft) 1.8S 1796 9.2:1 90/5400 105.5/3000 2.0E 1979 9.4:1 110/5400 119.5/2800-3400 i200 1979 9.4:1 125/7800 163/4700 i240 2396 9.4:1 136/5000 206/4100 Manta 400 (road) 2410 9.7:1 144/5200 210/3800 Options GM Strasbourg automatic transmission was available as an alternative to the standard five-speed manual. The transmission choice is basically down to what you prefer as they are both good, the automatic being more lively than you would expect. Other options available were Sliding steel sunroof, headlamp wash-wipe, rear wiper to name a but few. Many of these items were later incorporated into the range as standard. Opinions Not surprisingly the Manta collected quite a few bouquets along the way. Autocar magazine said : "....it provides a typically refined GM package at a price which is more than competitive with its rivals.... in the performance car value-for-money stakes, the Manta GTE is now one of the front runners." Motor magazine gave the Manta the thumbs-up with: "It's still hard to think of any rival that can match it's combination of practicality, roominess and stylish looks, let alone its new found economy and refinement...... And on top of that it's damn good fun thanks to punchy performance, an exquisite gearchange, and terrific handling.....nice one Opel!" 1.8S GTJ Manta The 1.8S GTJ was the base model for the revitalised range. It featured the new 1.8 litre OHC engine with a basic level of trim. This model was only available for 12 months, after which time it was supersceeded by the standard 1.8S GT 1.8S GT Manta The Base level model as from 1982. It had a slightly better level of trim than the previous GTJ model and again was powered by the new GM 1.8L OHC engine. It gave the Manta a respectable level of performance and good fuel economy Manta Berlinetta (1981 onwards) Following on from previous Opel ranges, the new facelifted Manta also sported the Berlinetta name. Once again it was the extra comfort model with better soundproofing and a more luxurious trim level as standard. Manta GT/E The fuel injected GT/E become the model that most people associate with the Manta. It was a very well appointed model, the 2.0 litre engine gave superb performance and the stylish Recaro Interior that was introduced for this model gave the car an even sportier feel. Offered in 2 body styles and many colours, this model was very well received by the public. Manta GT/E Exclusive The GT/E Exclusive was the final incarnation of the Opel Manta. It was initially made as a special edition model by Irmscher, the Opel owned Styling and Tuning company. This model featured specially moulded Twin Headlamps, (the first car to sport such items) and a rear spoiler on the coupe, derived from the Manta 400 rally car. All the modifications were cosmetic, but it gave the final years of Manta production a new lease of life. Manta 1.8S Exclusive The 1.8 Exclusive Hatch was the replacement for the GT. It was the final model available with the OHC engine and hatchback body style. Featuring the twin headlamps and a revised level of trim, it offered great value for money. It remained in production for just 12 months but was sold in quite large numbers begging the question why the such a popular model was ceased. Special Edition Models Manta i200 The i200 was a strictly limited edition model, converted by Irmscher GmBH to homologate the Opel Manta into the FISA group B rally category. The 2.0l engine received special treatment to increase the power output to 136 bhp. The front square headlamps were replaced by a pair of twin lamp pods and a large rear spoiler was added, both taken directly from the Opel Manta 400 model. A completely new interior was fitted featuring an Opel Blitz design fabric on the Recaro seats. The models were considerably more expensive that a standard GT/E at the time and this, very few of these cars were ever made in RHD. Due to the i200's status as a fully paid up member of Group B, they have become very collectable. Manta i240 TTe i240 Manta was another Limited edition model, from the Irmscher stable. It was not homologated into any FISA category and as such was made as a road going high performance model. The exisiting 2.0l engine was increased to 2.4l and the injection system uprated to cope with the extra fuelling required. Many other uprated components were available to order although the Opel Blitz interior was also fitted as standard, along with twin headlamps and a Manta 400 rear spoiler. Many of these cars were also fitted with the Irmscher 'Road' bodykit. This model was even more expensive than the i200. Only a handful were ever imported to the UK Manta i300 This Model, another Irmscher developed car, was offered with the GM straight six 3.0l engine, a logical choice for improved performance. It was the first 6 cylinder Manta available since the TE2800 of some 15 years previously. To accommodate the larger engine, several modifications had to be made to the front subframe and many uprated components had to be used. This made the cost of the i300 very high. The performance however was worth every penny ! This is the rarest of the Irmscher models with only one known example being imported into the UK Manta 400 The Manta 400 was the jewel in the Opel crown of the 1980's. It was the full blown rally example being, like the i200, homologated into the FISA Group B rally category. The road going version was fitted with a twin cam 2.4 litre engine, derived from an Opel Rekord diesel bottom end fitted with a specially designed cross flow Cosworth Cylinder head. Power in tuned rally form, could top 400bhp, but in the road form it was much tamed. The road going versions were also fitted with the Opel Blitz interior and featured as standard a Limited Slip Differential and a rally sport gearbox. It was generally regarded as being the best normally aspirated rear wheel drive car of its time and its considered by most to be the Holy Grail of Manta ownership. Courtenay Turbo When Chris Courtenay got hold of a Manta in the mid eighties, he breathed fire into it and another legend was born ! The Courtenay Turbo Manta was an aftermarket conversion, but is still worth a mention due to its high quality of construction and phenonemal power output. By chaning the compression ratio and fitting a turbocharger, the Manta had power to spare. The clever use of an electonic boost mechanism, frequently coppled with water injection, made the car powerful but still driveable everyday. Several examples exist in the UK of this firebreathing Manta.
  22. In 1980, Vauxhall designers built a one-off prototype special Cavalier Sportshatch in metallic silver, hence the name "Silver Aero". The car made its public debut in October 1980 at the NEC Motor Show on the Vauxhall stand. The idea of the Silver Aero project was to offer existing Sportshatch owners / buyers the chance to upgrade their cars to Silver Aero spec in three phases. Phase 1 This was a sports interior. there were a pair of black leather Recaro seats with electrically controlled backrest cushions and lumbar supports. Grey carpeting with black and white trim and door panels featuring special graphics gave a modern look to the interior. A Voxon radio / cassette (expensive in 1980) was incorporated into a special centre console. Phase 2 This phase addressed the exterior with a special bodykit made of glass fibre and included a nose cone, lower front spoiler with built in fog lamps and indicators, mouldings on the sills and full underbody skirting. A spoiler was fitted to the tailgate while a special rear spoiler with built in bumper was found on the rear valance. All exterior glass mouldings were in matt black. Compomotive alloy wheels with 215/60x15 Goodyear tyres finished the package. Phase 3 The main feature of this package was the 2.4 litre turbocharged engine which produced 150bhp. This was built by WBB (Racing) Ltd. and Turbo Torque Ltd. Special vents were let into the bonnet to dissipate the turbo heat. Sadly the project did not get past the one-off prototype. The car still survives today with less than 25,000 miles on the clock.
  23. Ive got some photos from the open day at Ellesmere Port, I was there in my i200. Memorable day out and I remember Jays car well.
  24. A666 MFC has been the subject of a little bit of chat recently on here and on the Farcebook group. Ive not seen the car for a while but I understand that it is in a good state of repair and has been well looked after recently. Go on.......you know it makes sense!
