I've got an itch for a turbo set up, I currently have a H/C/I set up. AFR 205s ( milled to 61.5 cc),cam is 224/228 581/588 114 lsa, ported fast 92,EWP,underdrive pully, and pacesetter 1 3/4 headers in an 02 TA M6 car with strange s60 4:11 gears.
My question, would I need to change my cam or would it be fine for FI (thinking turbo). I was also thinking I would get a set of 317 heads, and of course all the fuel and piping.
Any advice would be much appreciated and any suggestions on turbos/turbo piping kits,brackets k members ect.

Cam will be fine. Might need to change those rear gears though.

Yeah I that's what I figured(on the gears) what's the best or most common gear3:50ish or ?

HexenLord

3.73 is usually the highest but reserved for the guys with overdrive. 3.23s work good in cars without overdrive. The better power band from a turbo can afford to use taller gears, and they usually help good with traction too.

Thanks hexenlord, anyone else got suggestions, what kind of power level would be safe on 02 ls1 bottom end,I would like to make around the 650-700ish range, should I use a 5.3 instead of the 5.7 in the car now, get better pistons??

Not saying mine is safe but I'm over 800rwhp 20psi on pump gas/ meth on a 130000 ls1 bone stock except cam, springs, pushrods. Heads never been off nor intake. The life of the engine is in the tune. Afrs stay 11.2 or fatter and 14 degrees timing.

I'm a big fan of a centi car for manuals. See too many big hp turbo stick cars get there *** handed to them other than on the Dyno.

I'll look into them also, was thinking I would do an auto if I get a turbo, maybe a turbo 350
