Hey Guys,

I am new to this forum. I wanted to know what boost(psi) most of you guys are running
and with what mods. What horsepower and speeds are you guys reaching at as well.

I'm trying to get an idea of what a UK EJ20 or EJ22 engine can produce with mods.

Any advice or help are welcome. I am trying to see about a US Impreza project with a UK spec EJ20 Turbo engine install.

Thanks,
kevin

Welcome to the forum, Kevin!

For what it's worth, my car is standard except for Scoobysport back box and ramair panel filter.

My boost peaks at 15.5PSI and holds at 14.5 ish. This is apparently about right.

With bleed valves and all that malarky you can take it up to 17 apparently - Nito is a good source of information on this, but he's gone mad and fitted a front mounted intercooler (FMIC), electronic boost controller, bigger turbo and many other toys too. I think he's still running on standard ECU and he's getting 320ish BHP from a UK spec engine (EJ20)

Good luck with your quest!
