I love those. They look like a mini corvette. I seen one with a 283 in it.
I also had a neighbor that had a 283 in a Triuph 7. The guy that bought it from him, yanked the 283 and threw in a small block 400 with 450hp + a 200shot of NOS. He used to take money from sportbikes in the late 90's. He pulled consistent 9's. But it wasn't really road worthy at that point. Mainly a dragster he pulled out on the cruise strip.

Everyone on this forum has just about asked that same question. LOL LOL LOL
If you run 12 psi you will never shorten the life of the motor. After that you are pushing the envelope. You can push 15psi but you will shorten the life of the motor. Some people on here get away with crazy boost. I stay under 15psi myself. I pushed 14 for a day for fun. then the car got some radom none associated problem.
250hp your good. After that you are pushing it. Some run 300. That is your call and $$$$.
It also falls under which turbo you have. Some turbo's will produce like 200hp at 5psi. But your spool time will suck prairie dogs.

I have a GT2554 and a GT2560, both are cool. I prefer the 2560.
