the 5sfe can handle more boost than - 6G Celicas Forums

when i first installed the turbo i ran 5psi. then after awhile i was bored with it, turned it up to 10psi, NOW the boost contoller loosed up on the highway and i was back to stock. so i got home turned it back up and put a lock nut on. i just set the boost by eye. i get in the car and drive 5psi...8psi...10psi.. 13psi bab! i was like ehhhhh should i keep it? so i made a few runs. holy crap theres a big difference from 10psi to 13psi. in first ill launch so i dont sit and burn tire then shift hard into secound and it will spin for a few seconds then one u get traction around 3k then at 4.5k u loose it all again the tires just break free when 13psi is coursing through its veins lol. 3rd gear will just chirps the tires when the boost hits the pick up in crazy. donate so i can dyno lol. college is eating me.

Good to hear itchy; I was pretty sure it could take up to 10 psi; 12 with a proper fuel system. I think most of us are just being cautious tho

OOBE

They'll take it...you just need fuel and cool air. >

damn 13 psi. so the stock engine can handle this then that awesome to hear. does the stock ecu do all of the reatrding in timing since you have an OBDII system?

ask DG performance about how high boost can be before the engine goes. As he said, and I quote, "I turned the boost up and it was Great till my engine blew." Turn the boost down, or walk home.

I hate to be the bad guy, but that's just what he said. I think he was boosting 14lbs.

Dave never had a BTM. He was running the 5sfte the old school way with the timming retarded manualy.

IS there really a risk of blowing up your block? b/c that seems impossible. More likely a piston ring or rod. So if you get super nice pistons, etc, I don't see why the 5sfe can handle larger amounts of boost.

be carefull and dont go boost crazy. keep it at 10psi like u had all this time.

i could probably turn up 3s up to 25psi and have a nice run with it.... but id have a damaged engine if i kept something like that set for daily use.

I put 2 holes bigger then that in my 7a block :/ Throwing a rod at 5k RPM does wonders to the block heh >

Hey itchy, here's a great deal on st185 rods for sale. They fit fine in the 5sfe.

well, the 5s-fe will hold up for a while assuming little engine wear, but when I first came to 6gc, I had a turbo 5s in my old mr2. it was great, for a few months, I was steadily running 13psi even kicked up a little more a few times, but that came to an end pretty quickly after that.

So what happened to your motor?
