Do I need a RS2/7A FPR? RS2 injectors on 3b around 340 bhp?

[Jonas_R]

Well,

I just started to consider something. Iam going to run the RS2 Replica injectors from 034motorsport (already bought them from Corey).
The goal is around 340 bhp with RS2 EM, 3" turbo back, RS2 IC, Hybrid turbo properly going to run 1.7 bar.

But the question is, that unless I get a RS2 or 7A FPR i wont really gain anything from the injectors right? I mean the 3B runs 3 bar, the iam guessing that the RS2 injectors will properly run less full at 3bar.

So do I need to get a FPR?

Yes get a 7A one it's 4 bar rated and cheap as chips you'll find them on ebay or scrappers. The ABY one is also 4 bar rated but not as easy to come by.

The RS2 one is 3.8bar rated and quite a bit more in price.

Yeah oki, I can get the RS2 FPR at like 50 euro so that aint that bad. Actually my etka says that the FPR from the 3B and ABY are more expensive then the one from the ADU. Guess i better call my audi dealer and double check the prices.

Yeah and the 7A is like 20 euro from new.

But I guess i should just go with the one from the 7A, is it a straight swap? And is oki to run on the stock fuel pump? It is brand new and I dont want to buy the motorsport pump.

Straight swap according to other threads by the 3B owners

If it's 20 euros new then buy a new one.

Yes will be o.k on stock fuel pump but make sure you change the fuel filter.

My pricing was in regards to 2nd hand FPR.

Hi Jamo,

Yeah just bought one from the stealer and the price was just under 20 euro

Have you tried to change the injectors?
