My friend has a boosted celica which is kinda like the Gsr not in same way, but im referring to the 1.8L part.And it has 11.5 and his car boost around 12psi daily.I always thought when boosting your compression had to be low or either high compression low boost and serious tune.I still remember a guy on here I will not name him.He thought after replacing his oem headgasket with a cosmetic on a ctr he could boost it safely.
