itll spool real quick, be fun to drive but dont expect to make 283429472497 hp with that turbo

 

Mines 1.00 a/r divided take a bit to spool but pulls like crazy when it does! Also on a 4.8

 

Is yours a Q-trim? If so, I have the same one and it does have just a bit of lag but Im glad it does. I can drive out of boost anytime I want, where as even a .96 P-trim wants to spool quite a bit sooner on same truck. It is actually hard to stay out of boost in hills and such, especially if the converter is locked with the P-trim. So you would be spooling much sooner with the .68, I wouldnt go with that one unless your planning a rear mount. You could always hunt around for a larger turbine housing though, kbracing might have something laying around.

 

I have a never used 76mm turbonetics for sale that would be a great turbo for a 4.8 I am really looking to get rid of it now.

 

pm me the info

 

Yeah mines a Q-trim. I never see it go into boost when im cruising even on pretty steep hills.

 

Pm sent.
