The D16A6 in my 91 Civic SI is burning lots of oil and has low compression in one cylinder. I may rebuild but another option is a JDM D16A SOHC Non-VTEC which I found for $375. My question is what are the differences? Will the intake, exhaust, mounts, alternator, etc from my old motor bolt right up. From what I have found it seems the JDM motor has different cams and maybe higher compression worth a few horsepower but info is hard to find.

Thanks

From everything I've read, the motor you're looking at (The soch d16zc) is essentially the same as our usdm motor(d16a6). My friend has it in his car with just a header and turns a little quicker times in the 1/4 than me and others of us with A6's, but alot of it is the driver. They might, MIGHT have a slightly more agressive cam, I've heard both yes an no, but if it is, its not ny big difference and i don't know about the compression. I believe the motor may be made a little stronger, as in out of better materials, but its essesntially the same motor.

Hey XOTIC_CRX sorry but i have to correct you on this he said a D16A not A1 or A6 or A3 nothing like that i have a D16A sohc non-vtec adn i cant seem to find specs on this that are solid!

depending on how handy you are you could rebuild the motor for the same price.

really ^ if you do it half *** maybe

id go with the jdm motor op

JDM is a lot easier, you want the 1.6L sohc non vtec zc it'll be a direct replacement for your d16a6 no mods needed. Just a slight bump in compression and a hair better cams.

How would it be half ***?

For the price given ($375) there is NO way you could "do it right" unless you got free machine work and were stealing parts. If you just tried honing and slapping new rings in it and regasketed the engine, then sure, that would be easily achievable; this would only be a refresh though - there is a high possibility the engine is beyond being "saved" without a true overhaul.

Just go with the "jDm y0!" engine OP.

You could always search kijiji or craigs or a local honda forum for a engine or fresh bottom end...

Let's see I can get complete rebuild kit from locate machine shop for 320 dollars. That includes all gaskets, new oil pump, new pistons, timing belt, all seals, new rings. If your handy you could hone it yourself. Only machine work needed is pistons pressed on and off rods. Maybe resurfacing and valve job. I could deffantly make it happen. Do what you feel more comfortable doing. Im just giving you another option.

Wow, that is cheap... Don't try that around me... Plus to press off the pistons is around $20 a rod around me... Also, the price you gave isn't factory stuff either though... I am curious... Why would you want to change the pistons if you weren't having it bored over? Seems like a complete waste (assuming you were keeping it stock compression and the likes)... People will do what they want I suppose...
