1.8 AVO kit MSpnp
 

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.

AVO T28 ball bearing kit circa the last millenium(including the restrictive downpipe)

3.63 rear gear

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
