The1.9 cam plate and head wouldn't hurt, but with the top being off, you better make sure they are damn clean. Then maybe some bigger nozzles. The 1.9 injectors might help a little too.
I'll give it a try then...It'll be clean don't worry about...I'll assemble it in the house..when the wife's not home..lol
So you want torque? Get a small turbo like K03 from 1,9 or K14, not bigger. Or if you like to play a little more, then vnt. Good thing, that you already intercooled it. What about exhaust? Get 2,25" minimum, turbo to back. Modded stock pump will be fine for up to 130hp and stock injectors will be fine too (if in good condition).
Ive got a K14 to put on.My exhaust is 2" no muffler,I'm gonna play withthe pump some..I'm not looking for crazy hp/tq numbers just a little more
