engine conversion?? mk3 engine

[steble]

how difficult is it to put a mk3 gti engine 8v or 16v into a mk1 cabrio???

8v a bit easier as OEM exhaust manifold & downpipe will bolt up, plus wide selection of 4 branches available. with 16v you need to custom fabricate something or buy off the shelf conversion manifold, choice is yours.

difficulty level from there depends on what engine management you want, vs. what you have in there already.

well i think it is some form of mechanical injection

that'll be k-jet then, if you kept the existing system a mk3 lump would go in mostly without modifications, just need to buy a dizzy adaptor gear from TSR so you can fit your old dizzy, plus swap the dizzy gear from the MK3 dizzy onto it.

with the 16v you could keep the k-jet system and run it on kr managment, but since most of the 8v stuff will need to be stripped out and replaced with 16v stuff anyway you may as well run it on the proper abf mangment.

with either the 8v or 16v, running it on the MK3 managment is an option if you can handle a bit of wiring, theres not really much to it tbh. main thing is you want a lambda probe fitting in your exhaust to get the best out of it.

I have various wiring diagrams etc to help you here, or alternatively if you supply your old engine loom + the MK3 loom I can make you one.

this sounds promising it sounds like what my friend did when he put the mk3 16v engine (actually from a seat) in his mk2

given the choice I'd be fitting an abf on abf managment, but it depends what comes up for a good price
