hey whats up guys this is the set up im running

95 impreza coupe

EJ18bottom end
EJ22t heads and cams from a 94 legacy
cometic head gaskets
arp studs
long tube headers to custom up pipe. Turbo is mounted behind headlight
walbro 255 fp
375cc injectors> from a stock SR20DET
front mount IC
i was planning on running a Garret gt2860RS
but its just not in the budget right now...
i got my hands on a turbo brand new never used from a civic turbo kit for 200 bucks so i went with it...it was a eBay turbo its journal bearing im only need it to last till August but it has a .63t3 exhaust and a .50A/r compressor housing hoping to run 15psi to start maybe 20 after i break in the motor...

was wonding if i could use a ecu from a LGT
and have a manual boost controler to turn up the boost

also was wondering if the 375cc injectors are enough...i was trying to find the specs on the ej22t uinjectors and i saw they max out at 380cc ...i know for a fact that the sr20 375 will flow over 450 cc so i figured they would be good to start out with


thanks for everything

Welcome to the BBS.

When you say LGT, are you referring to the 91-94 turbo Legacy, or the newer 05+ Legacy GT with turbo?

I'm going to assume you mean 91-94 turbo Legacy. With what you have, the turbo Legacy ECU may work, but the wiring is going to be different, ECU plugs are likely different, and it will probably be more of a pain to try and convert the wiring than running a piggy back.
