I have an FD stock port single turbo...my current turbo is a split t4 mount...1.15 turbine side and .60 compressor side......i am on the verge of buying another turbo .84 turbine side and .70 compressor side...any input or experience is much appreciated....looking for a faster spool and i only run appx 16lbs of boost....semi daily driver....please post feedback

 

1.15 is quite a large hotside for stock ports, .84 is completely on the other side of the spectrum for an fd, i believe its the smallest recommended hotside for a rew. that being said, it will greatly increase your spool, just make sure you get a divided one since you have the divided manifold, might as well take advantage of it, it helps spool as well.

 

If your turbo is in good shape it would save you a lot of money to just replace the turbine housing. They usually are not too expensive and sometimes you can find them used. I just let a barely used .82 T4 for a 35r go for $120 shipped. Something like a .84 or .96 would probably work alot better for you.

 

right on guys thanks for the input.....im working up to ordering a brand new BB but i figure i should know what size i want first.......thanks again for the input!!!
