I run this spec
Standard Engine running standard cams and 205 block.
WRC head gasket
Greys
3 Bar
Forge RS500 intercooler
Custom Ramair filter
-31
T34 .63 custom Turbo
Mongoose
Fully mapped by Karl Norris-Spikes 30psi and holds 28psi to limiter
It is producing a good 360-370BHP and that is without pushing the engine too much
Go for Greys mate
