i just watched a 67dbb put down a tad over 700. Weither those numbers are correct or not....i think that is a perfect turbo. You can still use it perfect on a road course and anything over 700 in useless of street tires.i like the pt67 with a 81ar good mid and top end
I would stick to the range of 57mm to 63mm for a road course. I run a 57mm with decent results (minimal lag and good power).Currently running a SP74 GTS, injectors are 850 with a custom fuel rail..
Can you think of a better turbo for just street use and maybe road courses?
What a/r are you running on your 67?I have the regular old BL67mm P-trim and it is downright the most fun I have ever had in any car I ever owned. The only thing I might be doing is going with the DBB67 when and if this one fails but this thing is an AWESOME street turbo. It has good spool and when set up right will make 700rwhp on a 6 speed and run into the low 10's or high 9's with a auto trans.
The perfect Supra street turbo IMHO!!
