INFO Mk3 Engine Conversion FAQ (All questions and answers here)

best way to say it is...if you want to fit the 02a type box (16v to you and me) then get one from a seat ibiza as it will be easier to fit and stronger than the 8v box

yep.

i can add that cable clutch conversion on the hydro clutch ftw! so easy to do and only requires a part from the dealer. cant remember what the part no is though.....

its off a transporter and i think a passat too.

also i'd say 280mm brakes will be more than suffice for road use.

oh and as for converting a drive by wire 1.8t engine, just need a mk3 8v gti throttle body, thats all that qpeng supply anyway. save yourself some money and get a used for like £5.

i agree, the 1.8t conversion can be done for under £2000, but along the way it is worth replacing a lot of parts with new ones and also upgrading lots of stuff. so i'd say be prepared to spend £3000-£4000.

if anyone wants any more info or has any specific questions about the 1.8t conversion, please ask!

also forgot to add:

if you use qpeng for the 1.8t you dont use the mk3 ecu.

1.8t need mk3 16v engine mounting brackets. the 8v ones are slightly smaller and dont give as much engine clearance in the bay.

and yeah i agree, putting the engine in is actually not that bad, its all the little bits you dont think about that are the problem and finding the correct part that will do the job.

good effort mike

really helpful thread here guys, cheers 

[LazyLunatic]

not promising anything.....

but i want to refine a list im making at the moment for parts needed for a 1.8t conversion, including rough prices, part numbers, etc. hopefully be able to through some pics in and a bit of a write up and slam it in a word document once im done. then i can make thread and get it sticky up here with it. would be good for me to have something like this anyway.

Thanks for clearing up some of the 1.8t stuff there lazy Good work.

[thai-wronghorse]

Very interesting and useful.

[Adam]

What do you do about clocks? Say i'm going from a 8v to a VR6 what would I do for that? Use the 8v clocks of VR6 clocks?

[Mikester]

Vr clocks. You just swap em over. With the VR6 engine, engine loom, and ecu. the car would essentially be a factory VR. And once delcared, you wouldnt know the difference.

[Mr.Tom]

Just a note about 8v 2.0l. I am told that they have a hydraulic clutch, rather than the cable clutch. Or at least, that is what I am told about my late 96 reg 8v 2.0 gti. Maybe someone could confirm this?
