Guest StarLoc Posted May 29, 2009 Share Posted May 29, 2009 Ive converted a few vaux c20xe engines over to turbo and im now going to turbo the engine in the xr3i, i know its probably easier to just change the engine Ive been looking it it today and reading up on the net, and it doesnt look too hard, What bits are the same from the cvh and the cvh turbo engines, i have the efi one , I have found the turbo and manifold, exhaust, inlet manifold and a spacer plate to make it fit the head The electric bits im thinking to use a megasquirt ecu, i have one that drives a coilpack from one of my c20xe`s Does the engine already have a lambda and airflow meter anywere or dos it just guess, i cant find them?

Admin Paul Posted May 29, 2009 Admin Share Posted May 29, 2009 Hi, i have done mine but used a Fiesta RS turbo block and head, the EFI electrics would plug straight in and you would only need to change the ECU / Map sensor / and ACT sensor and swap 2 wires around. I have details from when i did mine. If you are going to use your current set up you would need to pop a hole in the sump for the oil return from the turbo. Also i you use your block and head with the adaptor plate you would only be able to run it a a few PSI, so not worth it. The block and head are different between the turbo and non turbo one. paul Quote Link to comment Share on other sites More sharing options...

Guest Lee81 Posted April 24, 2010 Share Posted April 24, 2010 could you send me a link please?? I have a S2 turbo engine if any of you are interested. Was fully rebuilt a few years back and I have just replaced all the seals and belts. plus painted it all up. Its has ported and polished head and piper cam fitted.

Guest KarlosG Posted May 3, 2010 Share Posted May 3, 2010 (edited) If you are EFI already then all you need to do is wire in your megasquirt ECU, drill the block for the turbo oil return, fit exhaust manifold/turbo, and find some low comp pistons from any RST. No adapter plates needed, no inlet manifold needed, you dont need a AFM (MS uses in built MAP sensor) and no they do not have a lambda. The block and head are not different between turbo and non turbo, except for the oil return hole in the block, and Series 1 RST had Sodium filled exhuast valves. Turbo'ing the 1.4cvh is a waste of time IMO, just fit a 1.6! Edited May 3, 2010 by KarlosG Quote Link to comment Share on other sites More sharing options...
Guest 90_Spec Posted May 19, 2016 Share Posted May 19, 2016 HI All, id love to pick this up again as i have a 90 spec EFI Cabby which im restoring and will be turbo'ing with MS too, Karlos, you seem to be a resident genius on this, as ive seen your posts elsewhere, how did you get on with the MS in the end? i have one i built aaages ago and never got round to fitting to my Series 1, Would you still recommend it? Also, are the Rods and beaings the same as XR? with just a lower comp piston and drilling the block for oil return? ThanksRich Quote Link to comment Share on other sites More sharing options...
