i know stock a/r sizing for a t25 from an sr20det redtop is .80

i actually have an extra stock turbo laying around that i hcan verify this with, as well as all my friends that have the same motor..

well i started looking at my turbo the other day, and they ar sizing is .60
what the hell turbo is that? it still says garrett, but it looks bigger. it looks like it fits like stock, but it is bigger.. any idea if its another stock turbo from another motor? or did i get hooked up?

a Standard Garrett GT28 is .60 A/R

you got an S14 or S15 turbo. check your injectors. if they are not purple then they are not stock either. if they are purple be careful how much boost you run. both s14 adn s15 turbos ahve the ability to max out the stock 370cc injectors.

they are stock sr injectors... i had one that was stuck open... so it was flooding my engine... it was great fun..
how much boost can an s14 turbo run?
what do you mean s14 or s14?

on a side note.. i saw your dyno vid as well as that freeway run.. that sh!t was CRAZY!!!!!!!!! good job mang
