turboing the horizen
 

I have an 89 horizen auto and i kind of want to put a turbo on it from another 2.2l k-car. how plausible is it? I'm pretty sure most everything will bolt up since the 2.2l are the same, right? I'm a chevy guy btw. should I be able to just switch out the chip in the pcm, is there even a chip? chevy guy again. will i have to upgrade my fuel pump? do the 2.2l turbo have a larger injector in the TB? I'll prolly put a trans cooler on. any advice or websites that might help me find out more would be awesome. thanks

The two motors are way diff !!

whats diff about them?

Pistons, compression ratio for sure. A better block, crank and rods ...diff head and springs ..I think.

The turbo engines are lower compression and the heads have better valves, same size, just better materials to take the heat. The turbo engines use 4 injectors, either under the manifold for 1984-87 T1, on top for 1988 up and all T2 engines. The SBEC (engine computer) for a TBI engine lacks the circuits for the wastegate control, second injector bank, sync signal and will not read the 2 bar MAP sensor correctly. The 1 bar MAP sensor is 5 volts at atmospheric pressure, the 2 bar is 2.5 volts at atmospheric pressure and 5 volts at 15 psi boost. The rods may be the same, and T1 engines didn't have a special crank, T2 and T3 are forged cranks, and T2 engines have floating wrist pins.
