You're looking for an upgrade.. Linear or progressive? Stock injectors?t_buck09 said:i know everyone tells us to upgrade to a 4 bar, well i found a 4.5 bar fuel pressure regulator, would that work or would it flood out the injectors on a 2.5 v6?
I've never heard of someone upgrading only the fpr..t_buck09 said:
It's his V6. Thanks for reminding me, im got snowed in on the 2.0t for some reason. And yes, the mods i listed is on a 2.0t.PMI said:t_buck - is this on your V6 engine, or a different car?
nine - you are talking about a 2L turbo, right?
I thought you were up in the GB area, sorry. I don't quite understand that, , but Ragtop would know, ask him what pressure he recommends.t_buck09 said:i live in southern wisconsin with a v6, ive heard from tboy and raggy that if you upgrade the fpr you gain quicker fuel responce? idk
You can probably look up the maximum pressure the injector is rated at. The NG900 and early 9-3 had Bosch EV1-3E (red) injectors. The injection time was 2.5 msec at idle, and 18 msec max. at wot (from the WIS) Note that after model yr. 2000, the injector changed.9-3sleeper said:Im planning on running a 3.5 bar once I get my stg 4 software. im sure thats fine with stock injectors, but could I get away with a 4?
yeah, I surly dont want to push it, and I of course would talk to nick about adaptability before the tune is written. I am an '02 so I guess the injectors you listed are different from mine.PMI said:You can probably look up the maximum pressure the injector is rated at.

Point is though, "Stage N" is usually a package deal, and the tuner assumes you have a known setup. I would not mess with that unless you discuss what you are doing with whoever reflashed your ecu.
I feel pretty safe playing with fuel pressure b/c I was not changing the max boost (or revving the engine to redline), but with modified boost control, high revs, and high fuel pressure, it might not take much to create an lean condition so quickly the ecu can't respond to it, and... boom, instant pile of scrap where your engine used to be.
( not saying it is not fun to play, if you don't have to depend on the same motor to get you to work on Monday...:cheesy: )
how much does a cleaning usually run?Still Pete67... said:I'm a big fan of the 4 bar regulator,i put one on my V6 after having a chat to Raggy about it.
It wont give you any more power,but it does let you get up the revs a bit quicker and access what's there,in my case it also helped to get rid of that flat spot on the revs at about 2200/2500.
I would recommend giving the injectors a full ultrasonic clean at the same time as the new FPR goes on,that way you'll feel the full benefit of having a set of matched and flow tested injectors and the security of new seals and o rings...
I paid £11 per injector for a full strip down,clean and new seals and o rings,sent them in the post on Monday and they were back on the Thursday of the same week very well packaged with a full write up of the work they'd done,parts replaced and their flow rates.t_buck09 said:how much does a cleaning usually run?
