FPR upgrage??
So i have read lots now on the impreza FPR upgrade!
Question 1: Would there be any benifit for me with an Australian Delivered svx (stock ecu) using an impreza FPR, or is it only of use with LAN's ecu upgrades?????? Mychailo can answer this one easy, were you running a stock ecu when you did the fpr and maf bypass moad to yours?? Question 2: would a 1992 RS liberty turbo (australian delivered intercooled 2.0T ) FPR do the trick?? Or a 1998 gen 2 liberty FPR (any coments) Cheers, Jake

Hey Jake, The Impreza RS FPR alone will richen the afr to around 10:1 or 11:1 at WOT high rpm which is beyond the optimum value for an NA motor. LAN's Stage 1 ecu programs a richer afr than stock, so using LAN's stage 1 with the Impreza RS FPR would result in an afr that is far too rich, probably around 9:1.
The maf bypass + the Impreza RS fpr are meant to be a low cost substitute for LAN's stage 1. Using the maf bypass + Impreza RS fpr + LAN's stage 1 together would provide no benefit. It would be a similar result to using just the Impreza RS fpr and LAN's stage 1, but not quite as rich of an afr, probably around 10:1 or 11:1. I don't know if the Liberty fpr would work. The part number for the 2000 Impreza RS fpr is: 22670AA240. Try calling your local Subaru parts person to see if they stock that part number. If not, Auburn Subaru in the USA will sell you one and ship it for a very reasonable price. You'll want to speak to Jason Douglas in the Parts Dept. His email is jdouglas@auburnsubaru.com.

Thanks for the replies!!
The reason for my asking is because i can get the 98 liberty (legacy) 2.5 FPR for next to nothing, alternatively i can get an sti one with is 43.5 psi once again it will cost me very little Cheers, Jake
