U got any nice link to some place that sells Bosch or Walbro? RS4 fuel pump is way beyond the pricelimit.
Friggen 750$ is a bit too much

Thanks for good info. I already have a walbro. I wouldn't say it is bad because it is cheap, it was on my 800HP Toyota Supra (actually 2 walbros) and they were better than stock, same flow, used less power. All the single turbo supra guys use mostly walbros, so i bought it based on experience - mine and others.KayGee wrote:Good price on the turbos. You'll need bigger MAF housing for 500 Bhp. AWE, ASP and Jacob do aftermarket or go with RS4 item which can support around 500 Bhp.
60lb injectors can be bought for S4 and RS4 fuel rails. No one has reported maxing the fuel rails as yet.
You'll need an uprated fuel pump - Bosch (dear), Walbro (cheapish) and RS4 (dear) and possibly a adjustable Fuel Pressure Regulator if the idle proves problematic.
Although no one is reporting rough idling with these injectors as yet.
If you are not scared of a bit of work, might want to consider straight RS6 turbos. Slightly more work fitting them...should be able to pick them up quite a lot cheaper than hybrids though....
