Just got me S2 back on the road and since i rebuilt it she has lost lots of low and mid range torque.
DIY ported head, inlet and exh manifold (matched ports)
piper 285 T2 cam
vernia pully
S/Steel valves
Grp A felpro gasket
Cosworth forged pistons approx 7.5:1 CR
Rebored to 81.50mm
Lightened and balanced crank, flywheel and clutch cover
hi presure oil pump
DIY boost activated 5th injector @12psi
Holding 20psi
Stage 2 T3 turbo -31
pace double capacity intercooler
lagged turbo / manifold
usuall extras, chip, filter, exhaust, swirl pot etc.

what boost do you think i should run and also being low comp and a laggy cam is it worth putting the std cam back in to regain some low down grunt

cheers for any help
