| Re: The "4.9 liter turbocharger, stage 1" thread.
Anyone have any thoughts on my application? Keep in mind that it is hopefully going on a 2.3 4cyl with 7.8:1 compression.
BTW- I've done some calculations on the GM3 compressor side and it works out to be a 53 trim. I haven't gotten to the exhaust side because the center section is fused to the exhaust side via rust :rolleyes2
Once I get the center cartridge seperated from the exhaust side, I'll be able to measure the turbines trim and the exhaust sides A/R.
Just from eyeball comparing, the turbine appears to be no bigger than my aiResearch .60/.63, BUT, that is only looking at the inner portion of the turbine. The inside could possibly tell a compeletely different tale. From looks though, it doesn't appear to be any larger than the turbine that I am using currently. |
