| Re: The "4.9 liter turbocharger, stage 1" thread. I have ordered a GM-3 Warner-Ishi turbocharger for this project off of Ebay. It is oil cooled only and the turbo is fairly large. I don't think it has the .82 A/R, but I'm not for sure...What I do know is that it is a T3/T4 trim: I'll get exact specs when I get it through the mail...It's taking for freakin' ever (from Canada). I'm using this one based on what they did with the Fiero and the same basic turbocharger. The turbocharger is used, but for stage 1, it doesn't need to be all polished and fancy. It just needs to get the job done without falling completely apart.
For fuel, I will likely use a TBI system from a 4.5 liter for auxiliary fueling: if it can fuel an entire V8 engine with two TBI injectors, why can't it help out in the boost department when ran on a seperate fuel controller such as Megasquirt? I smell a winner here. The only thing I worry about is the lower fuel pressure on that system: any suggestions?
A GNX intercooler sounds good. However, if you're absolutely sure I don't need one for the 6 psi or lower I'll be running, then I won't bother with it for now. One more time: are you positive I don't need intercooling for the lower boost I'll be running??? I'll take your word on it... |
