z6 head on d15b2 block?
 

can i do it? it tried searching but yea..search feature doesn't like me..just need a quick answer thanks guys

Re:z6 head on d15b2 block?
 

Yes.

Re:z6 head on d15b2 block?
 

Most definately...just remember to use a timing belt for the z6 though. And run the premium grade after that, C/R bumps up a bit due to the b2's flat-top pistons.

Re:z6 head on d15b2 block?
 

You need to open up an oil passage in the b2 block so it feeds the z6 head and vtec.

Re:z6 head on d15b2 block?
 

Yeah, it's located near the center of the block, you'll see it after you take the head off.

You also might have to swap the tensioners around along with the belts.

Re:z6 head on d15b2 block?
 

how hard is it to open up the oil passage?
i'm looking to get the head that mycrx is selling

Re:z6 head on d15b2 block?
 

You take a little hook and pull it out. It's just a little jet. Takes about 3 seconds to pull out.

Re:z6 head on d15b2 block?
 

how much will it up the C/R cuz i'd like to be boosting end of spring only gonna run 7-8psi

Re:z6 head on d15b2 block?
 

i need help with the above question please...also does the head that mycrx is selling seem like a good deal? 400 shipped.. for z6 head, stg2 cams, new springs valves and retainers and port and polished?

Re:z6 head on d15b2 block?
 

Well, depending on what headgasket you use, according to jedi-calc (or whatever it's called...it's a d-series calculator) you'll probably be around 9.8:1 or higher. Not exactly the best numbers to be runnin boost on, especially if everything "down below" is stock. Remember though...this is not a definate number, there are alot of factors that can change your C/R.

Re:z6 head on d15b2 block?
 

----..i'm not sure now if i want the head or not..cuz i need to be able to boost

Re:z6 head on d15b2 block?
 

Don't worry about the compression. 9.8 isn't ----. b16s run 10+:1 (10.2-10.4?) compression and people boost them all day long without problems.

If you have an extra $100 bucks to spend, get the obd0->1 harness, or make your own, and then run uberdata and you'll be perfectly fine.


This is going on a long shot but I think that abaz/jeff's built ls/vtec is going to be running like 11:1 compression. But yes, obvisouly that is a built motor, but the compression is almost a point higher than what you'll be running + he is going to be running a ---- load more boost.

d15b2 block + z6 head + turboedit/uberdata + 8psi = no problem.

And on the same hand, it is just a d15b2 block. You can find them for free or very close to free($20 bucks).

2 last things

I know a semi-local guy that is running a b7 block w/ a z6 head and he is boosting like 10psi on a fmu and last time i talked to him he was still goin'.

There was someone on hmt here that had just finished up a 10+:1 comrpession motor and was boosting it and loving it. Said that he'd never go back to low compression motors again.

Depending on where you are you can have my old b2 if you're too worried about blowing yours up. I already gave my old old b2 to stealthmode for free so :-*

have fun

Re:z6 head on d15b2 block?
 

cool..i already converted to obd1 and multi point so i have a z6 intake manifold..sucks i already grinded the ------- dizzy mounts to fit the b2 head..lol..oh well..that's what a welder is for

Re:z6 head on d15b2 block?
 

lol

On aluminum ?

Re:z6 head on d15b2 block?
 

my friend right up the street owns a welding shop so he can take care of it.. but no.. i can not weld it with my mig lol

Re:z6 head on d15b2 block?
 

you wont regret getting the z6 head

vtec + higher compression = ownage w/ boost. drop a cam in the head and you'll really like it

Re:z6 head on d15b2 block?
 

its supose to already have stage 2 cam...its the one that Mycrx is selling

Re:z6 head on d15b2 block?
 

Stage 2 what? What is the lift? Duration? What was it menat for? N/A? Turbo? Teh Nawz? Who made it? What are the other stages like? Is stage 1 stock? Is stage 3 full race?

???

well mycrx has you down as a vouche a beleive... he just old me stage 2 crane cams he doesn't have any pics or anything..

Re:z6 head on d15b2 block?
 

lol, I'm not saying he's going to rip you off.....

I was just wondering what the specs are on this "Stage 2" cam you have. ;)

i said "stage 2" ass because thats all i was told...crane stage 2 cams

Re:z6 head on d15b2 block?
 

You forgot about getting a person to tune it, one major thing that is needed for it to run "safely"

except you can't get a nice new z6 head for that much. So when you throw a piston into a combustion chamber and bend all your valves up, open up your wallet.

i personally would not spend the time to set it up with that high of c/r if you're going to boost. I believe in the power of the d15, i mean i have a boosted b2, but seriously look into forged internals on a d16 or something.

Re:z6 head on d15b2 block?
 

9.8:1 isn't "high" compression.

I'm sure he can find someone in his area with a wideband or a dyno. Not that hard to do.

Grow a ------- pair of balls. 8lbs isn't ----, especially on only 9.8:1.

Re:z6 head on d15b2 block?
 

hey man just being realistic, but hopefully we will see right?

Re:z6 head on d15b2 block?
 

if the head had all that work, you may want to check if it has been milled.
other than that and the cam, go for it.

Re:z6 head on d15b2 block?
 

Yeah, i mean you can run 8 pounds on a stock b2 bottom end...if you wanna crazy retard your timing to keep from blowin your ringlands apart ::) Hell, i used to run a 13.5:1 d-series on pump gas and toulene, but i still ended up retarding the timing a good deal even without any boost, just to keep it from blowing apart. If you want to run higher boost numbers, build the bottom end instead and use the built z6 head. Then you can run your 8 pounds all day, but i'm just sayin that i've seen what those bottom ends can do, and stock is not that good on those. They have the weakest rods, cranks, and pistons compared to a a6 or z6. You ever take a look at those rods man? I've seen twizzlers thicker than those things ;D

Re:z6 head on d15b2 block?
 

crank is still strong though : ) and the pistons are the same as any other stock d.

Re:z6 head on d15b2 block?
 

Pistons are flat-tops, but still are just as weak as any honda piston. ::) I'm not doubting the crank at all, one of my friends runs a b7 crank up to 8200 rpm every day for the past 9 months now. He's gettin a little bit of knock in his bottom end though now. I personally just feel better with a thicker journal on my crank like an a6 or z6.

Re:z6 head on d15b2 block?
 

But here's an idea if you want to save money or are on a budget: Try swapping in a set of a6 pistons...they're dished so it'll drop the ratio a bit. Downside is they also sit below the deck a bit as well, but hey...it lowers your rotational mass i guess, slighly better rod to stroke ratio lol. And as far as rod to stroke ratio goes, the d15 does have the better ratio out of the d-series, so you can rev em slighlty higher.

Re:z6 head on d15b2 block?
 

well my idea for buying the head fell through...so here's what i'm gonna do... since i'm still in highschool (last year thanks god) I can only make so much money..so i'm gonna go ahead and continue with turboing the stock b2 and run low boost..just so i can have some fun..then when i begin working full time in the summer..i'll look into an engine swap and building it up nicely..it just makes more sense that way thanks for all the input guys

Re:z6 head on d15b2 block?
 

First off, GROW A ------- PAIR OF BALLS. 8 pounds isn't ----. 9.8:1 is NOT high compression. Please, inform me, who makes rods for a d15 again that are aftermarket? Last time i checked...no one does.

Upon reflection of my above post, boost the b2 stock, you'll end up blowing it up anyways and no point to waste the money on the headgasket and such for the z6 head swap and you'll be impressed with the power that it will make boosted im sure. (considering you'll be going from 80 to the crank to probably like 120-140 to the wheels. If you're going to spend more than $500 on a motor down the road look into getting a ls long block. and then start parting together the rest of the stuff for the b series swap. B series swaps...cost a little bit more? yes. Worth it? yes. You can rock out 250-300whp without a problem on a stock b18a1 vs. having to build the ---- out of a d series in order to successfully break past 250 (in most cases).

Re:z6 head on d15b2 block?
 

^^^I'm with this guy, except they do make aftermarket pistons for the D15.

8psi isn't ----, I don't care what turbo you're running. If your motor blows at 8psi you had some serious tuning problems and shouldn't have been running boost to begin with. I'd kick myself in the balls with my third leg if my motor blew at 8psi.

Re:z6 head on d15b2 block?
 

I've ran 8psi on both my mini-me setups and the head was milled down quite a bit.

I'm doing another B2/Mini-me turbo in a couple weeks, should be cake.

It's all in how its tuned =)

Re:z6 head on d15b2 block?
 

I'm think that the d15b2 has a shorter stroke compared to a d16a6 resulting in lower displacement, but are the d16a6 rods actually stronger than d15b2 rods?

Re:z6 head on d15b2 block?
 

theres a guy over at sohchonda.com that goes by zer0daze he has a d15b7 block with y8 head giving 10.7:1 compression and he boost 9psi 200whp daily no problem, reving up to 8k on a reg basis lately hes been known to turn the whick up to 12psi

he also is a uberdata mad man and has spent alot of time on the dyno getting everything right so it just goes to show you that like the guy above said, the tune is the key not D15s being weak, thats a horse ---- cop out that people that dont tune their ---- well use when they break 4 rods on 9psi ::)

Re:z6 head on d15b2 block?
 

like i said i'll run the stock b2 boosted til i start working full time after school lets out.. then yes..i'm gonna swap and build something sexy.. i'll be pulling in 500 a week with no bills to pay except insurance and ---- so i can handle it

Re:z6 head on d15b2 block?
 

dont let your g/f know you have extra money, that ---- will be in da neck

Re:z6 head on d15b2 block?
 

bahaha.. of course i'm gonna use 95% percent of what i make for the car
