Mass Air or SD

[blue90lx]

I have 89 2.3 and i was wondering is it ma or sd? Also what years was the mass air put on? Just wondering.

[EHardy1971]

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.

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

I had no idea.

[Rcoupe91svo]

my old 90 2.3 hatch was a sd and my 91 coupe 2.3 was MAF

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.

so i need to find a svo motor or turbo coupe motor? Would that be the best bet?

[blue90lx]

Do you know a link that compares the engines or one that i can go deeper into this?

[SlowJoe]

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.

can you use the standard 2.3 head? But i'm assuming if you can it want make as much power cuz of the sparkplug issue. How much you want for that block?

i think i was going to give it away at one time. i have 2 sets of 35 lbs injectors to

[blue90lx]

Also, what will i have to do as far as my wiring goes and computer? What all will i have to change?

If your going to give it a way i may come and get then. what about those injectors are they still good? By the way will the block have to be cleaned up again?

So you want to sell the engine and wiring to me

I believe you are right.

You can make the reg 2.3 work though. Just add a drain to the oil pan
