Title: fitting a 16v to an 8v car
Post by: laurielaeks on 18 May 2009, 09:03
hey, i was just wondering what i could all need to complete the conversion on my mk3 8v, to the 16v,

already have the engine and head and gearbox,

think i might only need the ecu and wiring, just wanting to make sure this is right?
i was going to just buy a 16v but i fell in love with my car lol,

Your also going to need to convert the clutch, I believe the 16v is hydraulic and yours is cable, worth thinking about your insurance as it will or may be more than a factory car.

this may help I did the same swap in my mk2 and had awfull problems with trying to get the car to run, it appeared to be fuel pump in the 8v not having enough pressure to get the car 2 run .I dont know if mk2 and mk3 are same set up

mk3 gti 8v/16v pumps are the same so thats 1 less issue, could get away with old box but its a lottery. if you plan for big power in the future dont bother, go to hydro.

yeah im just wantin to use as much of my original parts as possible to keep it as cost effective as i can fot the time being, what about engine mounts? front and back, would they still be the same? also can i use my old downpipe of the 8v?

No your going to need to fit the 16v system really as it is a larger bore.

1. Sell the block and box to a MK2 over and let them whack they're K-Jet bits onto it for an easy conversion.
2. Go and buy 16v and don't build a car that already exists.

1. No.  K-jet is for people who like killing engines.
2. Agreed
3. It's their, not they're, please.

The detail differences are myriad, you would be wasting your time.

However the OP doesn't have an ECU or loom - so it would be much easier to punt to a K-Jet customer (whether you like K-Jet or not).

So is it a 1.8 or a 2.0

so fitting k jet engine to a mk3 that is a really stupid idea, it's going to do a blinding fail on emissions come mot time due to there been no cat and even if you did fit a cat it would die very quickly. you allways fit ke-jet but thats really crap as it has more parts that proably wont work to try and find and be an utter pita to wire up

its a 2.0, he was able to use his original inlet, ecu etc when he put it into his mk2. i got all the 1.8 kjet inlet etc with the engine aswell as getting the abf mk3 inlet etc for me doing it to my car, not running kjet on my car, thats just stupid

im referring to the 'oh no dont fit kjet your car will explode' type comments

very repetitive and unfounded
