60-1

I want to make alot of HP at low boost levels. Which one would you reccomend me doing this with? T3/T67 or the precision SC63??? GSR engine fully built stock bore will be the setup used with either of these turbos.

Both turbos I feel need higher boost levels, enything below 14-15psi it is not worth it imo. My car makes about 370whp with the Full Race T67 though. Geoff has posted some charts of a low boost T3/T67 11psi This was tuned by Jeff aka Boosted Hybrid

But the SC63 also made 449whp with 14psi on Motormatrix's car. I think the T67 has more potential WELL know it does.

I am going to be buying one of these turbos and appreciate your info. More info please people!!!!!!

Either the sc63 or the t67/t3 full race turbo need higher boost levels to allow the compressor to become in its efficiency range. What I accomplish with the t67/t3 full race turbo is far beyond what I would have imagined possible for the 67 trim compressor wheel to accomplish at such a low psi level. The turbo is 100% drivable in terms of power production. You'll want at least a 1800cc displacement so you can get into the powerband quicker, in the spring I'll see how the t67/t3 will react with a 2.0L bore. I expect to see 450whp on pump gas around 1bar. I am shooting for 10's on pump gas, and this turbo is totally capable.
