How much hp can my 88' Gtu rx stock fuelpump handle?And how much psi should it be at?

 

Its not so much the HP, its how much fuel your needing(which ironically means your getting more HP, lol) but if you have performance intake, exhaust, ignition, and are planning on running a ported motor..a TII fuel pump would be a good upgrade. For fuel on a wildly modified(street or bridgeporting, full exhaust, intake, ported manifolds, etc) I would get the 540cc secondaries from a T2 and use the APEXi SAFC...properly tuned you could get an extra 10 to 15hp out it...in my case, doing the GTR swap, I am using a 3rd gen fuel pump..had a walbro, but it was not the right model, and using the 720cc injectors from Denso...just a thought.....
