High compression and 100k miles of carbon buildup dont like to suddenly feel alot more pressure from a turbo. |

i'm going to do a compression test and leak down test and take it from there
if i blow it up it gives me an excuse to go 383. |

If you keep the boost low (sub 5-6) PSI, and you don't get any detonation/knock, it stands a chance of lasting for awhile.
The vast majority that do what you are contemplating end up ruining the motor. They all say the same thing in the beginning too, "I'll keep the boost low, it'll be fine." Eventually, they get a bad tank of gas, get greedy with the boost, or the motor just lets go. However, if you aren't adverse to building a motor, I think you should go for it. You might consider a 355 instead of the 383 for forced induction. It's easier to keep the wrist pin out of the ring pack, I think the piston speeds are better, etc... Just run 2 more PSI of boost to make up for the power difference between the 355 and the 383. |

5-6psi on a 10.4:1 compression is damn high, on 10.4:1 , that many miles, and pump gas I wouldn't recommend over 4psi
And even then I'd expect to do a motor build soon. |

I disagree with this as well when it comes to a turbo build on a C4. I think he should turbo the stock motor, get all the bugs worked out, figure out how to tune it, and become familliar with the set up. That way, he isn't learning to tune the thing on his $5000 bottom end. Get it all sorted with the stocker. If the stocker survives it, great. If not, you didn't blow up your new mill. |

Also Lc1vette from the other forum built a bad ass turbo set up for his 96 CE. He works for a speed shop in NC now, you might consider contacting him. I'm sure he would be a big help in the turbo C4 arena.
