Hey everyone!!!
I was wondering if a D16A1 head off an 87 integra would work on my stock si block D16a6???

Please any info would be great!!

Thanks Mike

 

nah it setup differently, mucho mods and not worth the effort, if you want dohc go for a zc or just an integ engine...not too expensive i believe

 

All the blot holes line up...just tryed it about a half hour ago!!!
would there be any problems with the coolant and oil ports???

 

it won't work, its a dohc head on a sohc block. just won't work

 

I've been asking that question for a VERY long time, all I get is maybe,no ( with no reason as to why it wouldn't work ), or a simple yes. If it will bolt up, and the oil and water passages all lineup too, then the only question left is the timing... I've been told all you have to do is buy the timing belt for a D16A1 ( acura ).. I can't see why it wouldn't work. If you do it, let me know. It will create a low compression motor that is PERFECT for turbos, the D16A1 head has 1mm bigger valves, bigger and better intake ports and exhaust ports. The D16A1 head also requires you to use the D16A! intake manifold and Exhaust manifolds.. This would be one bada$$ setup with a turbo !!! I can get a D16A1 easy so let me know if it works..

 

ive got a complete d16a1 engine. should i try it on mine to answer the age old question?? worth it?

 

Let me know... sounds cool...

bolt it on and see what happens.

 

yeah the bolt holes line up but before you **** stuff up make sure the oil passages and other holes line up (where the head contacts the block) Let us know how it goes
(all of that is meant in the nicest of ways of course)

why not just take a d16a1 put it in a first gen crx take d16a6 pistons put them into it and run a turbo in that instead of rigging up a shitty setup....someone tried it before a while ago oil lines didnt line up shitty compression because of spacing he said and its dumb IMO buy a dohc put it in ur car dont ask how to put a dohc head on ur sohc.....and if u do this u may need to check into ur crank gear for timing if the teeth are different ur gonna fubar ur ****

 

best way to find out is...
take the head gasket off the A1 and locate it on ur A6 block...
see if all the oil lines, coolant and **** matches up.. if the main stuff fits... then u know u are being able to mate that head to that block...
then do viceversa... use ur A6 head gasket and out it on the A1 head... same deal... then u will know fo sho..
after that just use the A1 T belt, and play with timing..
like someone else said.. do a low compression engine, and with all bigger ports and valves , u should be able to get a better deal than a stock A6...
keep us posted

 

From what I understand this head off a a1 fits on 1st gen EW/d15 Si blocks and lines up perfectly, but produces realy LOW compresion do to the Si's having 8.7:1 compression to begin with.....

If this accualy WORKS, then that means I might be able to do a Mini-Me set up on my 1st gen E block! haha... I doubt it.

Make sure that Head is off a black top or it truely isnt worth it, 86-87 a1s had Vacume Advanced Distribs(like 1st gen CRX/3g Civics), while 88-89 had Electronic(like 2nd gen Rex's/4th gen Civics).... If its a vacume just stuff it in a 1st gen and call it a day. Or sell it to me for a dolla!

 

like I said, I've asked many time, but never got a solid answer...

 

There are D series engines and then there are D series engines.

If your current block is a EW block from a 1984-87 Civic or CRX there is a good chance that the D16A1 head from the 86-89 Integra will bolt on your block. You may have to modify some coolant and oil passages to make them line up, but it is do-able.

The easy way to go is to swap in the Integra engine/tranny combination. Or the Stock EW can be built to make a ton of power, but it involves being a real engine builder, using sidedraft carbs, and a performance-oriented cam.

DOHC is sexy, but not the only way to make power. The real secret to power is supplying enough air and fuel to the cylinders. That is where the side drafts come into play.

or i could just swap the whole engine in and mess with it. ive heard the tranny doesn't line up or somen but i can fix that.

 

The only reason to try this hybrid set-up is to make the engine low compression so that it can run a lot of boost from a turbo. As far as N/A goes, it would suck. So stop already with the swap the whole motor or get a ZC comments !! The only way you can make a low compression honda motor WITHOUT TAKING APART THE BLOCK is to put a D16A6 head on a D16Z6 block, but if the D16A1 head works with the D16A6 block then that just makes one more option that would be cheaper, and take less time... ALL the other hybrid D-series options are HIGH COMPRESSION ( above 9:1 ). D16A1 head on the D16A6 block would be about 8:1 I believe, perfect for a turbo.

I'm refering to the 88-89 integra head "black top", I just reallized that he said 87' integra.... I don't think the 87' will fit, but hell, give it a try !!

Another thing to keep in mind is the head bolts. I think they're different in lenght when comparing the one engine to the other. I have no idea which ones to use, but using the wrong ones won't hold the head on the block properly.

 

I've heard that before about the lenth of the bolts, but if push came to shove, then you could always stud the head, which is a good idea with a turbo anyway...

 

Everything lines up...the only problem is that the oil ports are too small...the pistons will work...i think i will just build up the D16A6 head and be a bitch and tell lil idiots i have a stock motor

thanks everyone for your help
Mike

 

hell ya!
