hi Joe.
Heres a pic of the exuste port

and some more pics.
The pistons Im running are custom made Turbo and Nitros use,made by ROSS Pistons with a 40cc Dish In them.
The valves are custom made Nimonic 90 with single groove keepers and conventional height Type I valve springs with 8mm stems.
The valves are a special shape(for turbo use)
The size and shape were copyed from a 450bhp raceing 2L Toyota motor.
using Remmele outer spring with stock WBX inner and ally retainers.
shooting for 400 bhp!!
we will see what will happen.
Joe would you sell me some shufel pins for my 2.1 WBX motor? so i can install them in England.
Also what main studs would you recomend to beefup the case clamping? also some barrings, STD 3 peice 2.1 rear barring set?
Thanks mate...
