well everyone has a good say and My opinion is to turbo and i prefer suck through or fuel injection injection. They're not difficult to do anymore but the way fuel injection injection with aftermarket computer is its awesome and extremely flexible. I mean look at the options. My favourite two makes are Wolf 3D Ver.4 and EMS Stinger or EMS 8840 (new).

I would either get a Fuel injection manifold and all necessary parts to run as a non-turbo,that way all the wiring, pumps return lines are sorted out then later fit a turbo manifold with forged pistons, properly balanced and pepared and retune the computer

Or I would start off getting a turbo manifold and turbo and set it up as a suck through using a t25 or t28 garrett and a 2" Su carby hanging off it then later fit a fuel injection manifold with computer.

It really depends on which way suits you.

Anyways I have an SR20DET in a Sunny coupe so I ain't worried for a while.
