I just wanted to hear some responses on any of the HT members using the Borg Warner GM-1 turbo. What are the pros and cons of it? How many WHP does it support?

 

I know some of you guys are runnin this turbo. Even if you arent can I have some info on this snail?

 

Well. The GM-1 is similar to the GM-8 for the 6.5 diesel pickups from 1992-1993 CK pick-ups. Part# I-171076R that is the replacement. The GM8 is about the same as the GM-1.

Here was a quote from one of the users.

[QUOTE=GM8Pimp]
The IHI RHC6 GM8 measures 2.756" major diameter and 1.968" minor diameter on the compressor wheel. There are NO minor diameters of TO4E that measure 1.968". The closest you would get would be the TO4E 40 trim which measures 1.870"...BUT..the major diameter is 2.950". A difference of a finger nail on each side...quite a difference in percentage and overall flow potential.

Now moving on to what is closest- The TO4B S which measures 2.750" major and 1.904" minor.

Here is the TO4B S which has a max choke flow of 37 lbs/min or roughly 17.7 m³/min which equates to roughly 625 CFM. Take the rules of 150 CFM per 100 hp and you'll see that the TO4B S is capable of enough flow for 300~500 hp. 300 hp comfortably, but 500 hp IS A STRETCH, especially on a small displacement engine. You'd likely see most of your hp taper off in the 350+ range

Now onto more facts courtesy of IHI. The closest current compressor map that you'll find is located here:

Thanks Shodan man for the info Thats all I wanted to hear at least 300 hp is good for me .
