It's SD. I think the MAF 2.3's started in '90 or '91,which is when they went to the dual plug heads.

I think it was '91 because Mag's 90 is speed density.

What all is the diff between the standard 2.3 and the svo 2.3? Other than the turbo just motor wise. I plan on taking my 2.3 and putting a turbo on it, not wanting a whole lot of power just something to play with.

i think the whole motor is diff. block (drain back tube for turbo) crank,rods,pistons and head. they say the 8 spark plug head flows good with a little work and exhaust seats.

finding a turbo motor with a good head will be hard to do. i have a block with fresh 20 over bore,crank, and fly wheel. i think waypastcrazy has a set of rods only thing needed for short block would be a set of 20 over pistons.
