Are you using the 71 , 74 or 76mm version?
T6 frame 1.15 ?

From what I know, it's the T4 1.15, 70/94mm GT42.

Yea its doing very well, considering the cars been sitting untuned for a long time. Me and steve never worked out a time for tuning, so I asked a friend. I still would like him to take a glance at the map sometime in the future. Its changed alot since you saw it at Gotham.

Oh
Well the T4 housing
comes in 1.01 1.10 and 1.32 A/R
put some 1000cc Primarys in there
and crack it up to 32 PSI
That turbo loves 30+ PSI
you base Fuel pressure should be 42-45
any whoo
those are sick numbers coming from the "small".....hehe GT42

edit - speeds picked up to like 40k. wow does this car sound amazing, super loud spool up. need to get the ebc worked on though, hah so funny listening to the wastegate open and close mid pull. lets see some freeway pulls

I Kinda thought my base pressure was low. What primary rail will I need for those 1000's. Well I guess I have the frankenstien gt42 because I have a T4 1.15 divided housing.
Thanks for the comments. I am always trying to learn with this car.

[yep your right another option is the 1.15
was checking a dsm vendor before
a supra one does have a 1.15 as a option
so it has a 4" vband right?
fuel rail check with kgparts
