well i am wanting to use all my d series stuf and ake one good motor. i have a complete d16a6 ,a d16z6 crank pistons and rods, and a complete d15b7 and i wntto use the d15b7 block so peole think its stock.will the z6 or a6internals work in the b7 block?

 

no , wont work

 

will the d16 stuff only work in other d16 blocks?

 

what head do u want to use, becuz the b7 pistons will gain u more compression with a z6 head. if ur using stock b7 head with z6 pistons u compression will be really low since the z6 pistons are dish not flat like the b7. hope that helps

 

thanx

 

as far as the block goes...you can swap pistons around...thats about it. compression ratios will change dramatically by which combination you choose...d16 block with d15 pistons or visa versa.

the d16 crank & rods wont fit in the d15 block, different bearing sizes...even if they did youd be sticking way out of the hole with the longer rods and stroke on a shorter deck block.

 

well i have to change the head gasket on this d15b7.would it up the compression if i put the d16a6 head on the b7? and if i did thiswhat head gaskt should i use.

 

Your compression would not change if you used the A6 head on the B7 block. Both heads have a chamber volume of 38cc's. It's rumored though that the A6 head was one of the best OEM non-vtec heads, good cam grind and head flow. I've been looking into d-series piston swaps for about a month now and from what i've gathered it's not as easy as it seems. Biggest problem is the rod length/pin height.
D15's use 134mm rods (except VX/JDM D15B @137mm) while D16's use 137mm rods. The problem is if you try to put a D15 piston on a D16 rod the piston sticks out of the hole, try to put a D16 piston on a D15 rod and it sits too low. I'm sure there are some exceptions, but for the most part i've found this to be true. Your best bet is to stick with the same displacement pistons, ex: D15 pistons for a D15, D16 or ZC pistons in a D16.
There's a few things you can do with the parts you have:
1.)Build up that complete A6
2.)Put the A6 cam in the B7 and use an adjustable cam gear to zero the cam again, cuz it will be 4 degrees +/- depending on how you dropped it in.
3.)Use the B7 bottom end, buy a Z6 head and make it a mini-me engine.

 

what head bolts or studs will work in my 92 d15b8 with A dx head from a 91 i keep blowing head gaskets and cant fin them for my motor o and it has a t-25 turbo on it and a vx intake. thanks

 

So what if I'm going to use the d15b7 block but use the z6 crank and oil pump and order Nippon racing pistons that fit all d series would it affect it in any if I'm gonna boost 10 psi when I get head(d16y8) and block and tranny rebuilt?
