If you are on a budget, then a T28 turbo is not for you. yeah you can pick up the turbo on the cheap.. 1. it will not give you the grins that you would get even with a stock T3 turbo. 2. It is T2 flanged and will NOT bolt up to the stock T3 flanged L28 exhaust manifold. So you would have to either find a adapter or have a T2 flange welded on the L28ET exhaust manifold. I ran a T3 for a few years and really liked the quick spool and its a fun turbo for autocross, But it fell on its face really quickly after 45-4700 RPMs. It is a great budget turbo though and will bring smiles to your face for sure!!
chris51608:: for Fuel management on the cheap you can run Megasquirt and Spark. It is cheap and works fantastic! Or you could find a used SDS sytem or haltec system.
