what FPR do I need

[Forced_Fed_TSI]

I am pushing 18 psi on the stock 14b turbo on my 91 talon awd. so i am overrunning the stock fuel pressure regulator, now my question is which FPR do I buy, i see one thats the universal FPR. and the others are the aeromotive's that say -6an and -10an. which do i buy? and what exactly do i need to install it. is there a kit i will need or does it just bolt right up to where the old one would be? any recommendations on which FPR to buy?

Have you upgraded the fuel pump? Running over 15psi of boost will max your fuel pump out as well. Someone correct me if I am wrong but the stock FPR should be able to handle 18psi.

From the looks of your profile, you have a 255 fuel pump. That is whats causing your FPR to overun. Im not sure on which one to get, but would imagine a quick call to wherever you're buying it from would answer all your questions.

You want the Aeromotive one Part# 13109 but you will also need an install kit from Slowboy, ExtremePsi, Buschur or you can piece your own together by reading this.

alright cool, thanks for your help guys. I'm going to order the FPR on Wednesday and probably go with the kit from extremepsi that i think i saw. hopefully it all works out. and thanks again for all your help. i'll let you know how it does once im done

I personally have the kit and it is awsome. I ordered the kit with the ss lines and everything you need is provided for you including some extra fittings.

i found a Fpr with kit on ebay for 230 bucks and it looks like a pretty nice kit. it will be like 250 wilth the gauge. it seems like a nice kit. you can find it on ebay if you put in dsm fuel pressure regulator in the search area. let me know what you guys think. it seems like a good deal for fairly cheap. well not really but cheaper than some of the others

 

[droppinbottom]

Man look at the link I posted above.

Complete kit shipped with a fuel pressure guage and SS fuel line for 250 from a very reliable vendor on this site. At least this way you will know what you are getting.

 

[jott5555]

or get the complete bolt on unit for 155 another 20 for the gauge.. freakin a... why blow all this money when you can save some..

Maybe the fact that they are out of stock

 

[jott5555]

screw that! thers more venders plus dsmtalk and e-bay and craigs list... its a better unit.. thers a reason its out of stock..

 

[Forced_Fed_TSI]

i went with the kit that droppinbottom recomended for one because it sounds like a nice kit and two because the other one is out of stock. so it seemed like the better choice. i ordered it today. 230 total and i get it in three days. it says its a 1:1 ratio. does that mean for every pound over 15 of boost (since thats what the stock fuel pressure regulator is suppose to max out at) i should increase the fuel by one too?

 

[Forced_Fed_TSI]

anyone?????

 

[Rex2342]

The 1:1 rate means it rises 1 psi of fuel for every 1 psi of boost. When you install it set it to 38 psi while the vacuum line is disconnected.

 

[Forced_Fed_TSI]

so if im at 18psi of boost i should raise it how many?

 

[95-talontsi]

Plug the vac line to when you are setting the fuel pressure. You will get a more accurate setting that way. Its a real easy install I bought the same kit a few months back. Only probably I ran into was mounting it. There was an empty bolt hole next to my clutch master cylinder thats where I mounted mine carefull not to get the return line kinked when your mounting it. Post back if you got any questing when installing it. Good Luck

The amount of boost you run doesnt affect what you set the base pressure at. Just set it to 38 and you will be good to go. It will raise the pressure as needed from there.

 

[Forced_Fed_TSI]

so if i set the base pressure to 38 i dont need to do anything else to it to make the car run 18 to 20 psi of boost? i thougth i would have to get it on a dyno and turn it up to allow for more boost.. atleast this is what i thought was required. how else will the engine know how much fuel to dump for the amount of boost. im sorry if these are dumb questions.

 

[Rex2342]

No, once you set the base the AFPR does the rest. If your profile is updated and your running the stock 450's and a 255 your basically just making the stock setup a little more efficient by not over running the stock frp with the 255 pump. The ECU doesn't really know you've changed anything so it will still put out the same amount of fuel as before(someone correct me if I'm wrong). You would need an AFC to add more fuel where it's needed and bigger injectors to run more boost. Pick yourself up a logger if you don't already have one and monitor the fuel trims before you turn up the boost and possibly destroy your motor/turbo.

 

[jott5555]

ya you got some bad info somewhere.. basically what rex said.. you are just helping your fuel supply to the injectors by adding a larger pump and AFPR whcih is a good start.. your on the stock turbo.. really the best your going to get outta that turbo wiht your injectors and no fuel injectors to put larger amounts of fuel into the combustion chamber your only going to want to be about 16-18psi.. and chance's are since you have no real way to tune the amount of fuel the ecu is seeing your going to start to knock then the ecu will pull your timeing out and you will be at the finish like with a big :-( , if you want to run 20psi reliably you need to throw on a set of 550 or 660 injector's and a way to tune them.. via apexi Safc AND a datalogger, MAF Translator AND a datalogger or everyone's fav dsmlink.. and really dsmlink so soooooo nice and worht every penny plus more..
