Audi TT 1.8t

Good question! So there are a LOT of differences between the 225 K04 1.8t's and my old K03 1.8t.

To get the dual side mount intercoolers i had to swap over the intake manifolds so i could have the throttle body on the passengers side of the car, and in doing this i had to rewire a lot of the sensors so they would have the right length to fit.

Not only the turbo swap to the bigger K04, but exhaust manifolds, changing the n265 and n75 over as they both sat in vaguely different spots. A lot of the intercooler piping i had to fabricate because i had broken pipes from the front end damaged wrecked TT i bought for the parts. Injectors (although i havent put these in yet) to suit the bigger turbo with the tune, along with the 3" MAF. It also took me all day from 8.30am to about 5pm to fabricate the dump pipe from the wrecked TT to suit my aftermarket exhaust, a lot of fitting, cutting, welding, refitting and measuring.

That was pretty much it. Was a much bigger job than i first anticipated but it was fun and i learnt a heap.

225 hp engine runs lower compression too so make sure the GIAC guy knows that
