There is nothing wrong with not using an intercooler. My Merkur runs 15 psi with no intercooler from the factory.

Its pretty much going to be all custom work to make that turbo work on the car.

Your going to need a custom exhaust manifold with the proper flange for the turbo. If you need a external wastegate, that will also have to be added to the custom manifold. A custom downpipe will need to be built (with proper flange for turbo and/or wastegate connection).

Custom piping from the turbo to the intake manifold. You will need upgraded injectors (Ford's 42lb injectors should work). You'll need a wideband AF gauge (with 02 bung in the downpipe) along with boost gauge. Then of course is the custom tune.

Based on how you drive with the turbo your stock clutch should be okay; upgrade to the Exedy stage 1 if you want which will hold the power with no problem. 6 to 8 psi should be safe with no intercooler.

On 8 psi with an intercooler my 2.3L made 218whp and 216wtq.
