Does anyone know what the stock boost on the 93 viggen is? ive heard 20 psi but that seems higha nd seems like the car should then be A LOT faster

From a quick google search I fond that the mitsu turbo boost is 1.4bar (20.3 PSI). Matches what you;ve heard. Seems a bit high but not out of rational reason at all. Probably will want to double check that because my thought process is being altered by some substance (C2H6O perhaps....?!??)

i mean i definitely FEEL that boost, plus the car is heavy, but im just wonering then if its at 20psi what an these pistons and rods handle? i mean say i got an ecu downpipe exhaust, larger intake, and mbc or ebc, i mean can it handle that boost?

You should give Nick Taliaferro a call at He has a nicely modded Viggen and has put a lot of work into it. He's a nice guy to talk and can give you a lot of specific answer.

I looked into it a while ago. It all depends where you live.
I live at sea level so I probably see 16-17 psi. People in the higher elevations see closer to 20. The T7 ECU adjusts boost to give the predetermined horsepower. Hence thin air = more boost to get 230 hp. Hope i helped.
