what is the fuel pressure riser for, will i need new fuel injectors for this ? ? or can i use the stock ones and just add this and not have to worry about anything ? ?

what will i need if i get this ???

 

I take it you meant the Rising Rate Fuel Pressure Regulator (RRFPR)? If so, it's used to increase the fuel pressure based on the amount of boost raised. Many are adjustable, so you can fine tune it to match the correct pressure. As for the question about whether you need fuel injectors or not, it will depend on what are you using it for? An aftermarket turbo kit but low boost shouldn't require the replacement of factory injectors; however, if it is used for higher boost applications, there is a good chance that EMS will also be needed for fine tuning purpose.
Since you didn't mention what is your plan, this is the best answer I can tell you.
Good luck on whatever you plan to do

If you go with a standalone ECU you can just use a adjustable FPR and not the RRFPR because you can adjust the fuel pressure to a set amount without a need for it to increase.

 

How much or standalone ecu's.

i wanna race 1/4 miles and i wanna whats the best thing i can do for my car, maybe that means rising my boost.

help please

 

Well you could probably run a E-Manage (pm Boy about it) which is reasonably priced. The Link2 is about $1100 and the Tec-3s last I checked were about $2K.

 

what about the unichip or the utec ?? whats bad about those ? ?

 

Do you have a WRX or a turbo conversion? If you have a WRX your question would be better answered in the factory forced induction section. This area is more for the non-turbo cars that have been converted to turbo. Cause the UTEC as best I know is a WRX application not a RS-T application.

 

i have a converted garrett t3/4 turbo

would the unichip be good enough ? ?

 

A good person to ask would be the guys at Vishnu. I have no experience with the Unichips.
