Arkade Posted September 9, 2014 Share Posted September 9, 2014 Hi all, I'm trying to work out what options are available to me for an engine conversion for my A. Currently it has a (dead) 2.0 GTE and I'm looking to put something in that's more of daily driver than for show. I've seen people have managed to get 16v redtops in etc but I have no idea how hard this would have been? I guess I'm looking for something that's a bit more straightforward. Any ideas or pointers would be most appreciated. Quote Link to comment Share on other sites More sharing options...
Snowy Posted September 9, 2014 Share Posted September 9, 2014 Do you have a budget in mind? As to go from the GTE engine you will need to change the gearbox unless you're thinking of another CIH derivative? Thanks Quote Link to comment Share on other sites More sharing options...
611 Posted September 9, 2014 Share Posted September 9, 2014 Stick with the CIH engine. I thought the late A series in germany ran injection? as a nice 2.0L with injection would be just right for the A and wouldnt need lots of mods and different bits adding/changing like you do with the red top. just my view. Also i though i would have a quick google and see if i could find some info on the A with injection and found this picture of a GTE, must have been one they only did on the continent!! http://quoteko.com/opel-manta-gte/mercadoracing.org*imagenes-anuncios*38*361368*opel-manta-gte_1.jpg/ Andy Quote Link to comment Share on other sites More sharing options...
Arkade Posted September 10, 2014 Author Share Posted September 10, 2014 Budget wise not sure, depends on what's on offer I suppose. I'll probably look to do it for under 2k if I can. I do already have 2.6 V6 out of a Vectra which is tempting. But it's front wheel drive and I have no idea what gear box would be needed. I'm also more keen on doing a conversion that has been done before and works. Quote Link to comment Share on other sites More sharing options...
611 Posted September 10, 2014 Share Posted September 10, 2014 How about a nice honda S2000 engine?? that would fit in nicely and they are rear wheel drive :-) Quote Link to comment Share on other sites More sharing options...
MANTAMAN Posted September 10, 2014 Share Posted September 10, 2014 first thing i'd want to know is why is the Injection CIH is dead ? in good working order this engine would be a good daily driver in a Manta A, if it is very worn out rebuilding this engine is the first choice as you already have it, don't need to search for conversion parts, back in tip top from a CIH is as tough as old boots!! 611, Andy when i click on your link i get a photo of a Fiat 500 labeld Manta GTE The Manta A had a fuel injected GTE version from 1973 onwards, sold in mainland Europe and America, here's a photo of one i took in Holland last year - Quote Link to comment Share on other sites More sharing options...
Snowy Posted September 10, 2014 Share Posted September 10, 2014 (edited) Budget wise not sure, depends on what's on offer I suppose. I'll probably look to do it for under 2k if I can.

I'm also more keen on doing a conversion that has been done before and works. I'd personally go for a 2L SEH or NE engine fitted to an 1800 manta geabox, using the sump etc. Cheap, easy and reliable. You can even keep the gearstick in the standard position with a small modification to the gearbox linkage.

Arkade Posted September 10, 2014 Author Share Posted September 10, 2014 It's seized. A rebuild would get it going again for sure but it wasn't the best conversion to begin with and so I always planned that I'd put something else in. Has anyone tried doing a honda S2000 engine before?

Arkade Posted September 10, 2014 Author Share Posted September 10, 2014 I meant doing something that's well known as a good conversion instead of trying to break new ground with something that's never been done before Quote Link to comment Share on other sites More sharing options...
Snowy Posted September 10, 2014 Share Posted September 10, 2014 I meant doing something that's well known as a good conversion instead of trying to break new ground with something that's never been done before Just search the forum then for ideas. The V6 engine you mentioned has been done. Quote Link to comment Share on other sites More sharing options...
mantaray Posted September 10, 2014 Share Posted September 10, 2014 Option 1: 2.0 GTE engine, Option 2: 2.0 16v (red top), 1.8 Manta/ Carlton/ Omega g/box, Option 3: 2.5 V6, 1.8 Manta/ Carlton/ Omega g/box, Option 4: V8 Option 5: Jap engine All have been done before, option 1 is the cheapest and easyest and if fitted to a 5 speed box makes a big differance to the usability of the car. options 2 and 3, are more work, but if you are planing to do the work yourself should be doable for your 2k bugget. My V6. Quote Link to comment Share on other sites More sharing options...
MANTAMAN Posted September 11, 2014 Share Posted September 11, 2014 here's a question, do Honda engines rotate the same way as most other manufactures ? been told that they are the opposite, in a front wheel drive the engine would on the left and gearbox on the right this would mean to use a S2000 engine you'd have to use the rest of the drive train as well which could involve major fabrication.

611 Posted September 11, 2014 Share Posted September 11, 2014 Nothing wrong with a good old CIH, i just need to finish it :-) these guys do lots of nice CIH parts :-) http://www.krause-rennsporttechnik.de/shop/Motorenbereich/CIH Quote Link to comment Share on other sites More sharing options...
Arkade Posted September 11, 2014 Author Share Posted September 11, 2014 Cheers guys, fantastic info. Looks like I'm going to have a dilemma on my hands! Slightly tempted to stick in the V6 I already have lying around as I can see it's been done before. It's not exactly a low mileage engine but then they do go forever.

tony g Posted September 11, 2014 Share Posted September 11, 2014 Honda rotate normally these days. There were a few that went the other way but not any more. Tony Quote Link to comment Share on other sites More sharing options...
Arkade Posted November 10, 2014 Author Share Posted November 10, 2014 I've seen a 2.2 CIH for sale which looks almost identical to the dead 2.0 GTE I currently have in there. Does anyone know if this would be a straight forward swap? Quote Link to comment Share on other sites More sharing options...
611 Posted November 10, 2014 Share Posted November 10, 2014 Cant say 100% on the 2.2 but the 2.4 frontera CHI goes straight in. Well almost! you need to use the 2.0l engine mount brackets and there are a few pipes for cooling to re-route and thermostat housing so i think the 2.2 would be similar.

H-400 Posted November 10, 2014 Share Posted November 10, 2014 It fits,but if you don't have the original 2.2 inlet manifold you've got to adjust the location of the Manta A manifold. The inlet-outlet ports of the head are not similar as a "normal" CIH. As Senator wrote the thermostat hous is different (old Manta A wil fit with an adaptor-plate)and throw away the 2.2 camshaft. It's made for torque, not power. Herman Quote Link to comment Share on other sites More sharing options...
