b16a1 block with b18a1 head is it possible
 

ok hears the deal i have a b16 block laying around and a b18 head thoughti could do the exact opposite as a ls vtec turn the dowels up side down but im reading somtin about clogging the oil port does anyone no y and is this even posible its gona be a turbo motor so im not worried about compression becaust i want it to be lower and lossing alitle torque is not a big deal either if this is not possible can i use a b16 crank on a b18 block the spun a bearing in my b18 this is y i am asking thanks alot would appreiciat any feedback on this

Why would you want to use a head that flows less?

i no they flow less i no all that i just no the b16 has a stronger bottom end at this time i just dont have the cash sittin around for a b16 head also im not a fan of v tec motors turboed everyone i no has had problems or u put a vtec eliminator cam in witch is then pointless i just really need to no if this will work or not becuase if not i have to purchase a crank for my b18 thanx

I suppose you could do it but it seems so pointless, yes you would have to block off the oil passage in the block for vtec. but think about this, that combo is not going to make any more power than a zc or a z6 sohc motor. I understand not spending $4-500 on a b16 head to match the b16 block, but you can pick up a b18a block to match the b18 head for maybe $150, the b16 bottom/b18 head is gonna be a huge disappointment man seriously.

*edit* if you do decide to do it you will need to use b18 head bolts and and a b16 t belt.

I agree just get another ls block, they are dirt cheap. The only thing the ls has for it is the torque, which you would give up with the b16 bottom end. The only thing the b16 has is the high revs. I think you are trying to use the bad parts of each motor, so just like boosted b16 says you are making the equivelent to a zc or a z6 sohc. The dohc zc I had I bet would be better at least it liked to rev. Rebuild your block, or get another b18. I also rock the ls and the only thing that motor needs is a turbo to pull up to redline which it currently does not with no turbo.

I have an ls block I'd sell. Lol. I understand trying to make a cheap engine. But by time u r done and buy new gaskets u could have bought a used engine with just as much power.

But If u do it like said above u will need the b16 timing belt but also the b16 water pump.

do it and put mad boost on it, then go do titty rippers

I am with him!!;D

haha

hey i like yr sig. too

I always wondered about this. but never found then need to even trying it. but I want to see how it works out. I hope you have at lest the better b18b head not the older, more restrictive b18a head.

You can use the them and make a poor mans na high rev motor, the b16 bottom end loves high revs and the na head is easy and cheap to cam.

Stop saying the b16 head flows less than the others! its the cam that makes it flow more.


Its been flow benched and shown the b16 head has better flow and out flows the gsr head by 2 cfm with the stock cams in each head.

If that was the case I would use a GSR block with a ls built head with killer cams and retaners, port and polish, 3 angle valve job, ect.

The b16a head is a nice flowing head. for stock vs stock b16a and gsr heads perform the same NA. GSR head with stock cams + boost is better then a boosted b16a head with stock cams. GSR cams are better then b16a cams for boost.

stock vs stock gsr head is better, the combustion chamber is smaller therefore more compression and the cams are more aggressive than b16a.

if you put gsr cams in a b16a head you will not see any difference NA. I did this in my old b16a. because I was getting ready to turbo it.

2000 gsr cams bigger that 94-99 gsr, 94-99 gsr are the same as b16 cams.

buy a ls block theyre fairly cheap

Yea just get you a b18 block and use the b16 pistons to bump up comp some.

hmmm vtec to non vtec. Do it and lets see how it turns out lol

why would they put gsr cams in b16 heads if they weren't better? I think gsr cams has got to be more aggressive than b16a.

its been done. I did it I used 96 gsr cams on my b16. didn't feel anything when I was N/A. the only reason I put them in mine, because I was going turbo. you'll feel a difference with the gsr cams and turbo. this has been covered many times on honda-tech. if you look up the specs on aftermarket turbo cams and compare them with specs of GSR cams you'll see that there close to being the same, but the GSR cams are just alot cheaper.

oh ok. but the setups I hear with gsr heads are insane when vtec kicks! It seems like it would pull a lot better. but thanks for the info.

on a b16 you'll hear vtec louder then a GSR, when it "pops" it really does. I miss my CRX :(. now you got me thinking. LOL

I meant gsr cams not heads sorry. the b16 head with gsr cams is what I meant I heard. it sounded freakin crazy on changeover
