No 3 bar.
A4 1.8t's were 4 bar
so will any 4 bar pressure reg fit or dose it have to be a vag one
Doesnt need to be fitted to an S3 with a k04 if your thinking about it.
I would of thought a fpr is an fpr...
I am sure that as long as they bosch units then all good, but they are all different pressures so be aware of that. 4 bar from Audi A4s and Passats from 1995 to 2001 ish
im sure the fuel reg on my qts is a 4bar
I fitted a mk3 golf vr6 reg. its 4 bar and not too expensive.
will it do anything though going 4bar ?
Not unless your tune calls for it !
No benefit just sticking one in randomly
As Mark says...not unless your map needs it.
I tested adding one when at the Dyno with my S3 and lost power due to running too rich.
amd technik are goin to build a custom map when all the upgrades are done an they say it will need a 4 bar reg
I'm thinking of getting an mbc +diode mode.. But, I read that if I'm gonna add some psi I should fit a 4 bar fpr. Car is a S3 8L BAM. Does it comes with 3 bar or 4 bar?
Don't do it, none of it
get it mapped properly dont be so pikey unless you dont care about risking your engine
