Do i need to upgrade my fuel system?

[TRDcelica90]

Hey ill be running my garrett gt30 on no more than 15psi when its all going.. i have a walbro which i will install eventually but will stock pump (90' GT-Four) be ok with 15psi until i have chance to install?

Ive run 17psi on the stockie with no probs, but will the garrett put more pressure than the ct26??

also can anyone recommend a FPR, thats next on the list.

cheers

If your absolutely sure you had no problems running 17psi on it stock then i dont see how 15 will be any different?

Then again, there's a difference between thinking you had no problems and not having a problem..

Do you have a wideband O2 sensor and AFR gauge? It will help a lot when it comes to tuning/related.
