What else do you have in your fuel setup? pump, injectors? what about air? Got anything to maintain the right ratios? We need to know more about your setup...

If you have very good adjustability (standalone), the stock one should work fine. Otherwise, you might need something with a little adjustability. I'm using the stock one, so I can't help you there, but the Aeromotive Adj. FPR seems pretty popular.

I'd say leave the stock one in parallel with an external aftermarket. There are many.Also, did you notice if you say your name its "boosted sucka"thats funny.

He meant the stock regulator...not the stock rail. And the 4 and 6 thing you were talking about...I'm assuming it meant the AN size for the inlet.

If you're running a JWT and an AFC, I don't see why you would need an aftermarket regulator. If the JWT is tuned for 400cc injectors, I'm assuming they did so with the stock fuel pressure in mind. Might want to find these things out. The AFC will be your source for adjustments, not the pressure.

u guy dont get it ,in orde rfor my 400cc injectors to fit i had to buy a NEW FUEL RAIL,the rail needs a regulator,it has to whole on the ends

You're losing me....

Are you saying you can't use the stock regulator because of the new fuel rail? Then make an adapter and put the stock one back on! Or figure out how big the new fuel rail outlet is and buy an aftermarket one to fit. Be more specific....what else do you need to know?

the stock fuel rail on in all in one piece with the stock rail,it cant come off,now i have 400cc injectors,they do not fit the stock rail which in combined with the stock regulator,so i had a new rail made with requires a fuel regualtor,all i neeed to know is which one can i usethanx

Post by **cnichols** » Tue Sep 23, 2003 5:12 am

You had a new rail made....how are we supposed to know what will fit if it's a custom job? Get whoever made it to make you an adapter for the stock regulator.

how will the stock reg, work if its all in one piece with the stock rail dude

Post by **cnichols** » Tue Sep 23, 2003 5:12 am

It would have helped if you would have mentioned that earlier. I own two S14s, not an SOHC S13.

But, that still doesn't change the fact that I don't know what will fit, because your fuel rail is a custom piece. If you can't figure out what will fit or come up with a solution to a problem that should be fairly easy, maybe you shouldn't have turbocharged your vehicle.

Why not use the stock DOHC fuel pressure regulator? You can pick one up pretty cheap I bet. Also, metal can be cut...may not be the best idea to hack it off the stock fuel rail. I don't know because I've never seen one up close, but it's something to consider.

scrolll up to the 1st post i made pal,i clearly said sohci figured it out ,its just a mtter of the hoses fitting man,i was confused with term inlets,but i got it now,thanx anyways i guessand cnichols ur really a no help by the way,read the posts b4 u put ur 2 cents in

Post by **cnichols** » Tue Sep 23, 2003 5:12 am

ok....I'm the only one who was trying though. And I did clear up the inlet confusion. At least I thought I did.

Yes, you made it very clear it was SOHC. That's not what I was saying.

I didn't know that the stock regulator was part of the fuel rail...you can take it off on the DOHC and I don't see why you couldn't on an SOHC because I've never looked. I was only saying that you should have made it clear you absolutely could not use the stock one. That was the source of all the confusion...no need to get upset and pissed off. I'm really trying to help.

no hard feeling man ,i just one to get this baby runnning

Post by **cnichols** » Tue Sep 23, 2003 5:12 am

I feel ya, just got mine running last Friday...still a lot of tuning to do since this is my first time using a standalone.

Post by **andrave** » Tue Sep 23, 2003 5:12 am

I took my FPR off my rail on stock SOHC. Anyway whoever made your rail prolly tapped it for some kinda fittings (npt?) so call them up and find out. and then its just a matter of finding lines to attatch your fpr inline with that.and just so you know the new NHRA guildelines say you can't have more than 12" of rubber fuel hose in your system so it might be a good time to upgrade to stainless from your hard lines up.Besides, that 13 year old rubber hose is probably in bad shape ( I know mine is).
