Fuel system Upgrade??

[MR2-Good-4-u]

I have a 91 turbo it has 100k on the stock turbo. I was wondering if i could replace it with a t3/t4 upgrade and keep the stock fuel system without maxing out my injectors. Thanks.

P.S. I have a KO exhaust, HKS intake, Greddy Side mount, Hallman MBC, Greddy BOV, HKS Fuel cut defencer. Would i need anything else with the T3/T4? Thanks Alot!

You should be fun for 13-14 psi of boost depending onthe T3T4 you get.
Anymore boost than that an you are going to start to need fuel.

i would go with a ct-27 instead with you mods...t3/t4 requires more supporting mods than what you currently have...you will have to upgrade fuel system and engine management in the long run...

Ct-27 is the supra turbo right??

[JekylandHyde]

Nope. The Supra uses the CT26 as well.
The CT27 is a turbo from ATS Racing.

o ok but lets just say i got the t3t4 and still ran 14psi it would be a more efficient 14psi right?

^^are u getting the t3/t4 for a super deal or something???..how about a manifold??..much cheaper to go with ct-27...direct bolt on...but if you insist on the t3/t4....you will need more supporting mods to fully utilize it....

NO im not trying to say im set on the t3t4 i just used that as an example. But lets just say i got a bigger turbo and ran the same ammount of boost it would be more efficient that the stock turbo right?
