hiya as you may or may not know i have a s12 in a mk indy kit car
i'm running megasquirt ecu and need a few basic specs please

what should the timing be, i have it set to 11d btdc
fuel pressure
boost pressure
max bhp at what rpm
does a intercooler make much differance ?

many thanks for your help.

1. std timming should be set to 15deg btdc i believe.
2. fuel pressure should be bout 36psi according to the manual
3. std boost is 6.3 - 7.1 psi or on the silvia gauge 48 ish kpa (gauge is x10 so 4.8)
4. std is 135bhp cant remember what rpm that is.
5. i would wind up the boost without one, or you get detonation, and a holed piston.

hope this helps.

i knew

if you boost you will need a intercooler!!!!

i think the max bhp is reached at 5600rpm (on standard turbo & ECU) you may get it higher with the megga squirt setup

max boost (with an intercooler) on standard internals is 13psi (should put out 185/200bhp)

you can run 17.5 deg BTDC as standard, this gives better off boost performance.
