No cams while doing the motor?

HP capability will depend on your turbo specs and fuel and boost levels. I think if you turbo is capable your injectors will be too small. If you ran a decent sized turbo, and injectors were big enough, you should be looking at circa 350-400WHP.

A mate has a cam'd up 16v with a GT30 turbo, and he makes 550WHP on his.

Oh and recommendations...

Go to a GT series turbo, maybe a GT30 or 28 with a .48 or .63 A/R (depending on your spool requirements and power goals). Go get some 600cc+ injectors, and get a decent ECU! The new Link G4's are awesome and well priced. Maybe some Kelford cams Smile

All on the basis you are chasing decent numbers... maybe get a blacktop head too.

Thanks for the reply 4000GT. I'm planning to drift with this car, and a quick spool would be nice. Not yet on planning to change the cams.
What duration and lift you recommend for the cams?

Ah well, a drift car, you dont need enormous amounts of power, basically as long as you get a good tune in with good fuel, you will get all the power you need, maybe 300WHP depending on your current turbo specs.

Im running a Kelford cam, 288 degree duration and 10mm of lift.
