I'm trying to figure out what kind of turbo is best for a project that I am embarking upon and this turbo is on ebay for cheap. I need to know the exhaust A/R and compressor trim, or perhaps what kind of Garrett product it compares to, or even just a compressor map and the exhaust A/R. Thanks

 

well it depends on if you want to go stand alone or not, you can get a S5 turbo and send it out to get upgraded to a t04b

 

RIght now there's an S4 on the net pretty close to where I live, so i'm wondering if it works for my application. I know that although a rotary is a small displacement, it flows much more than the similarly sized piston engine.

I'm looking for a turbo to throw in a 4 liter explorer, and I havent been able to find any info about this turbo on the net and its not as simple as matching displacements like between 2 piston engines. I'm looking for between 5 and 8 pounds of boost and a turbine A/R between .5 and .6, and I have no idea what this S4 might be like.

 

so you just want a turbo to put on your explorer or on a rx7?

 

just for my explorer, its just that there arent many engines that came turbo'd from factory with that displacement (the Buick Grand National Turbos with the 3.8L V6 are about it). So i'm looking into unorthodox sources to see if they would work. All I need is what its turbine A/R is and a compressor map if possible

 

Anything off an automobile is too small.
Even a Buick GN uses a T3 turbo - too small.
