Recommended Posts

Ive been piecing together a turbo kit for my 240z ill be running a f54 block, there is alot of info but no recommendations what would be a good turbo for around 350-400 h.p. ive been looking at the garrett t3/t4 models but have no clue which one to buy. I want very little lag and dont need to rev it to 8k 6k is plentyand to have it kick in around 2500-3000 rpm any suggestions with explanation of them would be greatly appreciated

THANKS CHICAGO240Z

A TO4E-50 trim is a good compressor for a L28. But it will need a 1/2 inch spacer to clear the manifold.

 

If you are going to use the stock cam then use a stock L28 T3 turbine

 

if you plan to use an aftermarket cam then open up the turbine a little to a stage 3 or so. However, a free flow turbine will make a boost come on later. So it sounds like a stock turbine will be best for you needs. (t3 0.63a/r).

 

to make 350hp at the crank (300 at the wheels) then you will need about 20 psi of boost with a stock cam and a aftermarket efi system.
