Dynoed a 90 known as the Lemon yesterday. The car has been modified for a very long time. Was owned by the original owner of Enthuza exhaust. It has one of the old AVO t28 turbo kits on it. I recently went through it and revamped everything including getting rid of the link in favor of a Gen2 PNP. It doesnt make as much power as i expected it would but it is probably due to the age of the turbo and some of the kits design. The tune is also on the conservative side of timing and fuel. Car runs fantastic though and pulls well. Ambient temp was about 80F.

1990 Lemon
1.8 all stock
AVO T28 ball bearing kit circa the last millenium(including the restrictive downpipe)
RC 550 CC injectors
Gen 2 MSPNP with electronic boost controller
Entuza Exhaust(old one)
6 speed trans
3.63 rear gear
FM clutch(so worth it)

I also have an AVO kit on my 99, making about 210 HP on 11-12PSI

 

avo manifolds are great only restriction is the dump and they need a bigger cooler i am at 400hp on mine at the moment and there is more in it
