Aem Fuel Rail And Fpr

[LOUDCRXSi]

I was thinkin bout buyin an AEM High Flow Fuel Rail and FPR. I hear that both do not give any signifigant horsepower increases. Is this true to any extent? I thought i read a site that said that each will give an average of 8 horsepower increase. Let me know whats good. If i buy both its going to be in the next 2 days so get at me.

sounds like a lie, all the fuel rail does is allow fuel to go to the injectors, if anything its the injectors thatll make more hp(via better spray pattern or whatever). the stock rails are fine.
the fpr can make some power by allowing more fuel, and is a good investment for future tuning. if you dont want to cut the stock fpr(BM fpr), then definantly go for the AEM.

yeah i duno bout that site i read up on. I was talkin to my friend about it and he made me think bout if that site was rite or not. but im just lookin for somin cheap (not brand just mod) that will give me around 5-8 horsepower b/c im thinkin i need that much to get me into the 14.8s-14.9s

what do you have right now?

[civickiller]

an aem and afr are all for tuning pretty much, you stick a part on your car and you need more fuel so you turn your fpr up to get more fuel.

i think of this way as a bad way to tune. but im the kind of guy that says do it right the first time

i have them on my b16. its not gonna do anything noticeable. the AEM rail is capable of flowing more fuel than the stock rail, but it wont be max flowed unless you have a larger fuel pump. and even then it wont matter unless you are turbo or supercharged and can get enough air in to the mix. the fuel pressure regulator can get you a small gain if you raise the pressure, if you have a few mods like intake and header to help the engine breathe better.

get a obx header thats keep and you need one

[LOUDCRXSi]

well there both together if i buy them bambam. lol. nice faces. but do you think that i will be able to get 5 hp out of the FPR? or it a REALLY small gain? and for around $200 what could i get that will give me a min of 5 hp?

What do you guys think about the ecu chips on ebay????

[civickiller]

i doubt it. and chips on ebay suck

you know that im not gettin a obx header. im only gettin the greddy header.


And if the chips on Ebay suck then what can i get for $200 that will give me at least 5 hp. or am im pretty much S.O.L.???

it's hard to get something for under $200 that is GUARANTEED to get you at least 5 hp. And what have you done to your car already? I'd suggest getting a cold air intake, that would help your throttle response. If you're not going forced induction, extra fuel is almost useless. People with turbo/supercharger add extra injectors and pump extra fuel because of the higher pressure.

But the bottom line is...

For small gains, try I/H/E first

For big gains, try I/H/E first, and then save up and go big with either an engine swap or forced induction

It's hard to help you when we don't know what you HAVE!

I have CAI,High flow cat, CAT back exhaust, retarded distributor, spark plug wires....i want headers but the greddy headers are $375. I might just take my $200 and sit on it till i get the rest for headers. I just want somin to give me 5 hp by time the track opens so i can def be in the 14's. After i get headers where should i go from there? I know after the track closes im takin my car off the road again and doin the mini me head swap so what else should i do for this summer?

[jeef]

save a little bit more and get a nice set of cams, that'll put you up over what you want...

[LOUDCRXSi]

cams are a lil more than $375. and plus you gota pay for labor. i plan on gettin cams but thats after the mini me swap.
