ls head on d15 :)

I was looking on ebay at heads and cams and an idea struck me. What if I put an Integra ls D16 DOHC head on my engine? Because just imagine ,if it is possible,the torque and hp gains :) :) But a problem arose. It' has two cams and I have a d15 with only one cam :( Besides the machining needed to make it fit right what else would I need to get this to work if it's possible? But I do wonder why if it is possible why this is not common practice by others with d15 motors. maybe because no one plans on keeping them despite the fact that these motors still have decent hp potential.

I've never heard or seen a dohc on a sohc motor, I guess you could be the first. :)

he talking about those old school integra's with the zc, they make like 112 hp. but the jdm ones make like 130 hp. idk if its possible i just wanted to clear it up. those d series engines came in the 86-89 integra. oh and they are dohc

well if it doens' t seem to easily done to swap a 88 integra head, then what is a good head swap for a d15?

Also can someone explain to me what a "Mini-Me" conversion is?

anything mpfi will be better than the dpfi thats on there now

What about a D16y8 head? would this get higher gains than just adding V-TEC?

you cant just ADD VTEC onto your d15 head
a Y8 is a vtec head


some advice do some reading/research -i'm not trin to be an asshole just trin to help

i believe he was talkin about the d16a8 or a9 im pretty sure that was the code on those engines *integra*

Integra Ls motor is a B series, it wont fit on a D series motor. Unless it was the D16a8/a9. Then i dont know if it will fit. It wouldnt be hard to swap in either a D16z6/y8 from the 92-95 or the 96-00 ex civics...

Go to a junk yard and pick up a D16y8 motor for about $500 and drop that sucker in there.

the old integras have a D series engine...its a d16a8 or d16a9 and yes the head from one of those engines would fit on the sohc engine you have im guessing d15b7...but it would probably be cheaper to get the complete d16a8 engine from www.hmotorsonline.com its 450 dollars and shipping for me was i think 185.


but if you wanted to just swap out the head, then your going to have to get the head from a junkyard or ebay or wherever and go to advance auto, autozone, pepboys, wherever you get your parts and get the timing belt for the d16a1/2 (86-89 integra) and thats all i can think of doing off the top of my head, hit me up on aim if you have more questions about it...outlawxedge or pm me

Check post dates please, this thread is over 2½ years old. And more than likely it'd be illegal to put an older engine into a newer car. Not to mention, the y8 would be a better choice for performance anyways.

also, isnt he wrong anyways, a DOHC D16a8 head wont bolt onto a D15b block even if they are both d series...

at least thats whaty ive assumed to be true, as well as read on here a few times, as well as when looking at my DOHC ZC compared to my D15b7, they didnt look like theyd interchange.

not to keep a dead thread alive, but i know for a fact from personal experimenting, a d-series DOHC head will NOT fit on a d-series SOHC block. the head bolts don't line up, and the oil return passages as well do not line up. i got ahold of a D16A1 for the pistons and rods. after i had the head off, for shits and giggles i tried matching it up to my brother's D16A6 block he was planning to build for turbo. it proved to be a no go.
