Hi guys, im currently building a mk2 golf 4x4 shell i want to put a 1.8t engine in it, ive got to the stage where im ready for buying a donor engine, but which one is the best for tuning? by this i mean the strongest and best to work with. ive been told by a reliable source that it is the agu engine but just after a few opinions

thanks rob

Not that I'm aware of, there are a few big power 1.8T's going about with 1.9L capacity with no problems. Am planning on getting mine rebuilt to 1.9L within the next year or 2 when I get a big turbo sorted out. Was speaking to Grant Motorsport a whileback about 1.9 rebuilds and they've done a few now and recomend it with stronger rods etc for long term reliability with big turbo applicaions. Your project sounds good, looking forward to hearing how you get on.

Only real issue on the big turbo jobs has been some mapping issues AFAIK on the dbw cars, and some valve trouble on some engines. I think they are two piece valves and they fall aprt at 9500 revs. (God, what were VW thinking using them!LOL).

Otherwise AGU is a good bet, but most have doen a few miles now, so rebuild is a good way to start. TSR do a 2.0 litre I understand, dunno what it is like though.

Your MK2 will be a beast. You will have many friends here cos we all secretly love the MK2!!

im definately doing a full rebuild and will probably end up going to 1.9. im upgrading to pauter con rods and j.e pistons and while im at it i may experiment with the compression ratio. now onto sourcing on and choosing a turbo. anyone know what the ihi turbo will handle??

cool will have to investigate into the turbo side of things after ive got the engine sorted. anyone know a good place to source a agu engine, wiring loom and ecu?

Worth trying Sanburn VW breakers in Coventry. If they don't they might know someone who does. Always found them handy to use.

Cheers, Ed

There was something similar to this on Vortex about 4-6 weeks back. IIRC the news was that the AGU head mated to a later block might be the best bet. Something about the later block having extra re-inforcement and being stronger but I really can't remember the details. The man to talk to about this subject is definitely chris86vw on the Vortex 1.8T tuning forum.

Very true, but we tend to keep it quiet, silly handshakes, secret meetings and knowing looks kinda thing [;)]

Good luck with the project though, really want to do the same myself so will be keeping a close eye on your progress [:D]

There is quite a few varients of the IHI, Jabba's old AGU Mk4 had slightly over 400bhp with one of the bigger IHI's. Liamh on this site has 370ish on his IHI'd AGU.

It was a hybrid turbo..on the MK4 which did that, and 1.9ltr

depends on whay dyno you go to as to what figures you end up with.

mid 300's seems the norm for VF34 IHI'd cars (flywheel)

Going 83mm bore on JE pistons on the new engine (have 2 sets spare).

Largeport will flow more, but not sure on torque delivery and what low end losses vs top end gains. Never seen a largeport IHI on the same dyno same day as my smallport.

Hows your Ibiza coming on Bill, is she running the new spec yet?
