Evening people.

Quick question about the title.

What would the outcome be if changing the restrictor
Pill in a MY02 WRX from a 1.2mm to the STI 0.9mm? Am i gonna be slamming fuel cut alot?

I bought a dump valve which had a alot of tubing bits in. An then i found one with a restrictor pill. Its off a newage sti?

Just curious?

just found this info on another thread.

it appears the 0.9mm restrictor is in the JDM WRX, and the UK/EURO STI?

So it should be ok shouldnt it?

i played around with different pills and found the original was the best i tryed 1.1 1.0 & 0.9 they gave more boost but seemed as it came on to quick and fizzled out

how do you me fizzled out?

I was hoping the ecu would compensate for the difference. im not actually thinking of raising boost. just lowering it a little were it comes in. boost spools by 3.3k. but seems to step up an get strong (peak power) by 5k.

Was just hoping to lower that a little?

sorry should of said mines a classic and work different to yours eg smaller the hole higher the boost on classics and other way around on yours.

when i say fizzled out i meant it came on stronger and lower but seemed flat high revs
