Need Injectors and FPR ? i think?? help

[92vert240]

Maybe someone can send me a link to a previous post because i know this has been dicused. I couldnt find much in the search option.

Ive got a stock S14 sr in my s13 with the exception of a FMIC, 3" from the turbo back, wolbro 255 and 300ZX TT fuel filter.

My limiting factor right now is the 360cc injectors. I was searching and found something about a fuel pressure regulator and 550 cc injectors. I realize i will need a ECU tune after these mods but which injectors (brand, top feed, side feed, high/low impeadence) and regulator do i need?

Sorry for the noob question but in reality, im a noob to the SR . I want to run 14-15 lbs SAFELY. I will be running 14 on 110 octane at the track this week but would like to be able to do that on 93. Searching "boost levels" returned an everage safe boost level to be 10-13 psig.

555cc injectors are good for about 350whp safely+/- I would upgrade your maf to a n62 na300zx maf and get a tune. I recomend a Nismo adjustable fpr as mine has been flawless....By the way what color are your injectors? I thought depending on the year s14 sr"s came with 440cc/370cc depending on the year.

Injectors are a light bluish gray.

You got 370cc injectors the red ones are 440 and were on the s15 you should deffinetally upgrade those injectors.

Figured that. Im gonna go 12.xx on this setup first. Then i'll start upgrading.

I think w/ 110 octane and only 14 lbs i should be ok.
