3.5 FPR question

I don't think it's really necessary in a stage 2 car...

Some tunes do require it, but I believe that is tuner-dependent and also at a higher stage (Probably when you would need to upgrade injectors?).

this & that....

True and partially true!
It is more dependent on the tuner, than on the hardware. For instance, I have 750cc fuel injectors and go with a 3.0 FPR...on my stage 5+...
But guess what: for the stock injectors, at stage 3+, I had used a 3.5 FPR (it`s more like a Nordic/JZW use).

The FPR, in it`s self, is not a performance part, it just support other performance parts, in a synergyc system (most important, the ECU software, not necessary the injectors or the fuel pump).
So unless you have all the other parts that require the 3.5 FPR, it`s no use to put one on your car. If you use it ignoring the system requires, the car will not run right (worse gas management, bad knocks, s.o.).

Yes it will work in a T5 car

Will work in 900 from Engine V018403-- Onwards Thats a -97 MY motor. The tip of the regulator is a different size.

Nordic originally used the 3.5 on the t7 they tuned to get more injector flow out of the stock ones above stage 1. back in -99/00 Now we can get the knockoff injectors from china for cheap.

Also if upping the fuel pressure you need to be sure the pump has enough flow capacity at the raised pressure.

so i have a 1997 b204 stage 3+ tune with stock injectors and stock pump. is this something i should look into? im planning on upgradingmy turbo and fuel support to 19t and 60lb injectors then soon after a walboro 255.
