i have a 91 integra, and i keep hearing everyone raving more about the 92 to 93 integra motors. i found a 93 block for CHEAP, would it be worth it to slap it on there in place of the 91 motor? do i need to convert it in any way besides OBD1 conversation, is there an easy way to do this? harness?

 

I believe most of the difference is in the head

 

do i need to put in the WHOLE motor, or can you mix and match OB0 and OB1?

 

If you're going to go with complete swap over. I think it would be better if you went with the OBD1 for the 92-93 gsr motor. You should be able to find ECU harness that will help with the OBD conversion.

 

i would LOVE to have the 92 gsr motor in there, but i might have problems with smog in cali, and they are SUPER hard to find.

try that and see if you like it.

Cams, exhuast manifold, intake manifold and electronics are the main differences... same compression, same bore, same stroke...

 

reallyy... that wouldnt be AS bad. so the head and block are the same?

 

exactly the same. head, block, pistons, rods, crank, oil pump, strainer, windage tray, main caps.... yea all the same.

 

Its only a 10 hp difference between the 90/91's and the 92/93's motors anyway.
92/93 obd1 ecu's have much more support in the tuning world.

If you want more power on the cheap, research and find a nice Intake, Header, and Exhaust combo.

If you have alittle more to spend, find some PR3 pistons to raise the compression to 10.8/1, and run some Crower 403 cams, maintaining the stock redline with a mild tuning session. That should give you a nice gain.

If you have some more money to spend, get upgraded valvesprings and Crower 404 cams with the PR3's or P30 pistons, ARP rod bolts to strengthen the bottem end a tad, raise your redline to 8K and tune on a dyno with a wideband and chipped ecu, and you will be impressed, and so will the cars you leave behind.

But then again, some will say go lsvtec or B18c swap, so do some research on how much power you want and how much money you can invest in your car.

Sorry, I tend to ramble on a bit, my bad.

 

no way, dont worry about rambling, that was the best answer i ever could have hoped for. i really appricate it. but remember, im also trying to avoid smog laws. they seem to be a big problem for me in cali. hahaha.
