I am told it is a variant of the To4e T4 turbo....or better known as a stock turbo from an 87 grandnational. I cannot find compressor maps for it to decide if it will work on a low boost setup for my is300. I think I read of a dude that had one on his mx6 mazda but I have a larger motor and will only run around 6 psi (10.5:1 compression). I think the hot side is .63 and the cold side is .60. The compressor is much larger than a T3 SVO turbo though.
The stock grandnational is said to have 245hp and 355lbft of torque. Do you think it would make 320hp on my 3.0 six

 

hmm i think the flow chart if i can remember flowed to about 400hp at the limit but it may have been less. Yeah its like a 40 ish trim T4 turbo, but the turbine is about a .82 T3, i bet it would work reasonably well on an IS300

 

Yea, just gonna do a low boost ~5-6psi low buck setup. Aiming for around 300-320 hp until I get comfortable with whatever engine management I use, which will probubly be the AEM F/IC or Haltech f10x or maybee megasquirt.

 

Not on an IS300.

 

stock these cars are not that fast, I would just like to at least be able to have an edge on some of the newer cars that come out every year that are faster..
