at least 91 octane?? you need that in stock ls1's....
and 60mm is tad too small, leaves no room for improvement. i'd get a 67mm to 76mm turbo

Twin 60s are too small.... I have a t70 60 mm on my 04 mustang gt. Thats 281 ci. that kit should be good for your stock bottem end but if you want 575-600 you might need a bigger turbo.. You be spinning a small turbo with alot of cubes.. But it will be good on the street.

I would go with the bigger turbo. I ordered the same kit and after talking to all these guys i upgraded to a 76 mm. Did you get your kit yet? If so do you think you could take pics? Also how long did you wait on the kit? Im on month 3 now and hoping it will be done soon.

Sorry for the questions lol.

Well i guess im gonna have a little longer to wait. How long did it take for the first oarts to show up? Yeah uploaded pics would be sweet lol. That what i was thinking at first too, and then i talked to a bunch of people on here and they said i wouldnt be happy with the 60mm. You could always sell it and go with a different turbo.
