D15B8 with a Z6 head?
OK, well I have a d16z6 motor from a 93 civic ex.. I took the head off to find 3 of the cylinders full of water and rust. Mind you its been sitting outside for a year. Not the best place i know. But I plan on getting the head cleaned, the valves seem fine maybe get them re-seated. My main question is, I have a 95 civic cx with a d15b8 the 70 hp 8 valve turd. Would there be any benefit to putting the 16 valve head on that block. Would it be worth it? I read somewhere that the D15B with 130 hp is a 1.5 liter with the z6 head. Any truth to that? and would I see similar results by putting that head on?
Thanks to anyone who can give me some knowledge!

Youd deffibitly be beter off with the z6 than with just the b8 head but i think ull need new pistons too. they arent set up for 16 valve heads! They dont have the knothces for the extra valves. but if you didi the mini me youd see a huge power gain!

1992 Civic CX's and SOME 93's I've been told have the 16 valve pistons.
95's do NOT have 16 valve pistons, so you cannot do the Mini-Me to that block.
Also, he would not see a 'huge power gain' with the mini me
He'd FEEL a huge power gain if he did the Mini-Me with the EX transmission, but the CX/VX transmissions are GARBAGE!

I Completely agree! i need an y8 or z6 tranny for my mini me but i did feel a substantial gain for a d-series and hes running an 8 valve motor so i can only imagine he would only see a bigger results than i did with a y7/y8

No, with an 8 valve motor, he will see less results for 2 reasons:
A) without 16 valve reliefs in the pistons, you are about a sneeze away from wrecking your valves or pistons, I've heard of some people running mini-me's with 8 valve pistons, but don't have any proof, while I have pictures and documentation showing my 16 valve piston D15B8 running a Y8 mini me without problem.
B) "There is no replacement for displacement" the Vtec head will help, but personally, after swapping my car, its like night and day, the Vtec head gave my car some more pep, and it was fun winding it out to 7800RPM, but when it comes down to it, my B18B1 swap decimates my tires, spins into second, and chirps third, which I would NEVER be able to do with the mini-me.

Yea i no my d-series dont stand a chance aginst my freind h22 civic its just nasty, or his brothers 99 si. But for a d series it really dont get any better than v-tec. Unless you go boost. But if i were him id take the extra time and money and do the mini me he will be much happier. Be sure you get 16valve pistons!

I have a LS swap in my 92 cx, but I just want something else for my 95. the 8 valve sucks nasty *****.. which I'm sure all of you know.
Maybe I'll look into getting a B swap.

Chipped ECU, Mini-Me's make useable power up to about 7500RPM

My P05 ECU from my CX cost $125 IIRC to chip it and have it converted to handle Vtec by http://www.phearable.net I told him what I wanted, what I had done, and what redline I wanted, and he took care of it.

That doesn't make **** for sense...
"I have an LS swap in my 92 CX

I have a LS in my 92 CX, and I had a Mini Me in it as well, Leave the 95 Stock, enjoy the 40mpg, and boost the 92 with the money you save.

Re: (Dasfinc)
dude for the price of converting to vtec and rebuilding the head.....you can just buy the d15b. they for for like $500 for the complete engine....then you got a fiesty little motor with cheap potential....have you heard of the vitara setup. you take a d15b then buy tuner toys rods and suzuki vitara pistons and rings. i think you can get like 300whp with the pistons and theyre cheap as ****. the rods are golden and theyre a little over $200 FOR FORGED RODS!!!! seriously for like $1200 you can have a blown d15b with reliability.

For forgetting the $250-300 he will need to drop on a transmission that doesn't blow also, and if its gonna boost it, he might as well do LSD, which is another $500, so its more like 'for $2000 you can have a blown D15B with reliability'
while for $2000 you can also have a blown B18B1 with reliability too...

True but 2000 for a motor with a perfect rod/stroke ratio, forged internals, turbocharged, reliable LSD tranny....probably 12 sec. passes.....how can you go wrong. The D15B is without doubt the best D Series engine.

With all due respect to the D-series, after getting a taste of a NA B-series, and the small difference in torque makes HUGE difference...
he has 2 Civics, why make 2 monsters? I think he'd be better off investing money into the toy he already has instead of pouring money into 2 cars.
