  1. twin 40's was all the could afford at the time, and along with their fast road cam, he was, (and still is), happy enough wih the performance. he's since swapped to their milder cam, (so its not as revvy), as it kept failing the MOT on emissions at the time.

    i still have the same fast road cam in mine.

  2. both my 2.7 88 Exclusive couple and my best mate's 80 srb coupe 2.2 CIH's were built at Torque Developments; dont know how much my mate's conversion cost, as he had his done about a year before mine, but the total bill for mine, (which was carried out in 96), was £4995. this felt steep at the time, but as the work on my mates 2.2 was excellent, and he's a manta nut, I decided to go ahead as the standard 2.0 performance couldnt compare. he runs twin 40 Weber carbs and I EFI.

    I have JE pistons and rods, along with a 2nd hand Mantzel crank-which needed extensive regrounding, as it was in a state.(the JE's from the US were more easily available than Mahle's at the time, but were expensive).

    I can say performance of both engines feels similar, although I have more torque.

  3. further to:

    because my MS1 is so old it wont talk to tunerstudio without updating the firmware-which I'm having trouble doing;

    question: can I do a straight swap with an MS2 unit? are the pin outs the same, as my DB37 connector sensor tails are all plumbed in? Megasquirt UK is doing:

    MS 2 V 3 Extra Code fully assembled, 2.5 bar MAP sensor, 2.5 Bar MAP sensor, good for normally aspirated or Boosted Engines to 30psi max, and fitted with 2 coil drivers so will run a 4 cycl wasted spark, this is the recommended way as you have complete control of the timing and can also use the onboard rev limiting facility, + your Fuel Injection, comes with a resonable MAP to get you up and running, wiring diagram you can download from this site (Link), DB37 Plug, and DB9 cable to connect to your pc, Price £475.00 + and Shipping + VAT

    which I'll buy provided I can do a straight swap.

  4. hi,

    I've finally plumbed in my MS1 v1 I've had sitting in my garage since 2006, and will be setting it up on Saturday via the latest TunerStudio MS which now I've registered; question: how do I connect the tacho MS lead to the Manta? looking around the engine, there's no obvious place.

  5. hi Pete,

    I have a question to ask:

    whenever i saw you car back in the day, I noticed you have a fire extinguisher fixed to the nearside front interior; can I ask what spec it is, how its attached and the supplier please.

    I ask this because the previous Exclusive my engine was in, (E828DJN), perished at the side of the M11 back in 1996, due to a fire in the fuel pump assembly area; anything I can do to not go through that experience again, I'll do. to watch your pride and joy go up in flames, aknowing there's nothing you can do about it, is something I wouldnt wish on anyone.

  6. yes Herman, its leaking fuel under load; it was fine initailly, but since We've been messing about with the injection system in order to get the car running, we noticed it leaking at the weekend.

    it makes sense the tyre valve angle, as I'd say they're comparable in size; will the thread be the same though?

  7. Herman,

    I need a fuel rail pressure relief limiter valve from a vauxhall frontera mk 1, as the one on mine is leaking; I cant find one on Ebay. do you know this valve and is there an equivalent from another manufacturer?

    I run the Frontera rail as its safer than the standard GTE multi hosed one; I've posed the question to Andy on the parts supplier section, but thought I'd ask you directly, due to your knowledge on all things Manta.

  8. yes my 2.7 was built at Torque Developments back in 1996. I first bought a used Mantzel crank from Rocket Ron, who used to work in a tuning shop in North London.he was selling manta parts as he switched to an R32 Nissan Skyline

    it was in a bad state and needed lots of machining to get it useable. I then bought JE pistons and connecting rods from the US, and the bottom end was bored and stroked to  97.25 x 90 mm as Pete said.

    the standard 2.0 head was replaced with a Carlton 2.2 along with oversized valves and solid lifters; the cam I'm not sure of- I never asked about it. the whole engine was blueprinted and cost me £5 short of five grand for all the work.

  9. so the fuel in is the 17mm nut end end of the rail with the return under the regulator,  on the Frontera, Snowy?

    i'll purchase a guage asap thanks.

    and yes Buz, please provide photos of the rail with fuel lines attached.


    and thanks Mick, i tried swapping round the flow and return pipes under the bonnet, but it made no difference.

  10. I'm getting poor pressure on my Frontera fuel rail, with little or no fuel getting to the injectors. I've replaced the pump with a Senator B 3.0 one, and I can hear it running on startup, but the engine starts but not run after a few seconds. I suspect the regulator but not sure; question:

    is the fuel line input just under the regulator on the Frontera rail, or is it the one on the rear of the rail wtith the 17mm bolt? the Haynes manual I have is for the GTE but i'm running the Frontera rail on a 2.2 Carlton head with big valves, sitting on a 2.7 bottom end.

    its doing my brain in, so need advice, PLEASE..
