Hello everyone. I have the following set up...
2.0 turbo blob impreza 2003 wrx, full 2.5" decat and straight pipe (up pipe is standard with cat drilled out) then I have the standard top mount intercooler, pink injectors, Walbro 255 fuel pump, vta dump valve and then vf35 turbo . Been remapped also.
Getting 315 hp which I'm a bit disappointed with but the worst part is Its taking 4250 revs to spool up so in my head it feels slower unless I rev the knackers off it then you have less pulling time in each gear.
I recently added the vf35 from td04 which spooled at 3k with the cat in the up pipe, was running 266bhp before pinks vf35 and up pipe cat taken out.
Please help. Lot of money to spend to be disappointed with results :(
