Most T-4s have much higher A/Rs. A T4 @ .63 A/R shouldn't hurt performance but you won't realize the full potential of the housing. Are you certain PTE will configure this turbo with a T4 housing?
This turbo should easily beat the snot out of a T66BB - end of story.
There are plenty of 70s out there configured with T4s - either turbo will run 9's. I expect the 6765s and 6768s to run in the mid 9s with properly sorted out combos - maybe faster - but not in my car. My goal has been easy mid to low 10s without having to lean on it real hard. I know my setup COULD run in the 9s but I don't intend to push it that hard - remember - it's a STREET car! If I want to go faster I've got another car a little better suited for all out 1/4 mile assaults.
I know it's hard with all the choices but try to stop over thinking and just go and buy one!:biggrin:
Good luck!
I am goign with the t4 becasue i know i will want something bigger down the line, that and i just spent the $1100 for TA headers, so it is finalized.
Bent6, you said a t4 with the small A/R will not do much good? will it hurt performance? Should i just step it up right away to a 0.81.
The reason i am not going with a 6768, is it is alot more money for only 35 ish HP.
My old turbo was a T66 BB with a 0.63, and it did mid 10's. i am afraind that this turbo will preform similarly to my old one, which would be a total waste of money in my eyes.
One last thing guys, i am at 3500', so i need more turbo to hit my 9 second goal. If this turbo can only do 9's when the stars align, then it is not for me. That is why i have been leaning toward the 70mm, with its proven 9 second ability.
