Possible turbo 318 build

it would take 2 of those to make 500.

When it comes down to it.....you need a minimum of a 60mm Compressor inducer and a .85 A/R 58mm exhaust housing and when I say Minimum.....I mean minimum for a single turbo.

The turbo you linked to is 10mm smaller and would suit upto a 2.5L 4 cyl perfectly.

The 60mm Compressor turbo I recommended as a Minimum will flowout around 500whp....and by that I mean it will make 625-650 at the crank, on 1.4 Bar/20 psi and race gas.

Here is where you need to shop for a turbo:
