Hello guys, my question is with supporting fuel mods can one run a 20g at 25psi without tuning? I have found a GST with everything but tuning and want to know if the previous owner driving it like that could have harmed the engine.
 
With supporting fuel mods, you absolutely must have some type of tuning platform or damage will occur. Doesn't matter what turbo you're running at what boost level- you can't use larger injectors on the stock ECu without a tuning platform.

Yeah I figured thanks for the quick reply and clearing that up for me.
 
Post a picture of the turbo although I'm sure this guy would probably counter with a "it's a bastard 20g".
 
You could run higher psi from an aftermarket fuel pump and maybe larger injectors? it might "run" and pray that it wont explode maybe it will even run for a while. Nothing about that is something I would try out with my own car LOL. Soon as your getting into a larger turbo tuning needs to come into play. How else do you manage more fuel flow and injector operation.

Sounds like its probably stock and the guy put a walbro255 in it without putting a fuel pressure regulator in and cranked up the boost on the stock T25.
 
Yeah it all seems super sketch he also claims the engine is built in some way but doesn't know how. Whether he's got the setup he claims or not I think I'm gonna pass. Shame to because it looked pretty clean as far as the body goes.
 
Always try to know as much about what you're putting your money into as possible.
Saves you time and money later in the long run...
Def pass on that.
