I plan on taking a D16A6 cylinder head and bolting it to my D15B7 block. Now, I looked up hp ratings and the D15B7 makes 102hp and 92tq(stock)---D16A6 makes 108hp and 100tq(stock). I dynoed my car with my mods now minus the igniton and got 98whp and 82wtq. With this head, how much of a hp jump am I looking at with my mods?

Also, I was told to take the internals of the A6 and use them in my engine. I looked at the strokes and saw the A6 has a 90mm vs. the B7 84mm. Will this work in my block? I want to rebuild my motor(184k miles..) with forged stuff to go with a higher compression with a shot of nitrous.

Any help(other than telling me to search, because searched) will be greatly appreciated.


Mods: k&n a/f,sri,skunk2 i/m,aem fuel rail,accel direct fit H.O. coil,bosch wires and plat.4 plugs,shaved head,4-2-1 header,2.25in. exhaust,zex race 6.7Lb flywheel,exedy s1 clutch,HD axels,synthetic fluids everywhere.

 

my friend put a d15 vtec head on a d16 block and that **** ran hard vtec hit hard i like it then timing belt broke and bent all the valves

 

that sucks

 

See what bearings they told you to use with the D16 crank and the D15 b, I would like to know, also how thick a head gasket.

 

I got 88-91 civic and 92-95 haynes manuals so I'll look to them for the specs on the crank. I'm thinking I'll go with either Z6 or ZC headgasket.

well thanks for that useless piece of post.

 

seriously man, i put a a6 head on a 1.5 block and could tell a big difference. the main journals on the 1.6 crank will not fit in the 1.5 block. if u can just get the whole a6 block and build that and overbore if u have to.

hope that helps

You sir have helped me out alot!! I didnt know they were different sizes. I thought all D-series stuff was interchangable. Thanks for the help!!!

 

A6 is the same casting as a B7, the A6 cam is bigger. D16 crank won't go in a D15B7. You could use a D15B crank and D16 rods, Bense might have his D15B crank FS still.

 

i think you should check this month's honda tuning magazine. there was a huge article about putting swapping d16's and d17's together. certain parts here and there to make a pretty decent amount of power

i know it's not directly related but you might find some of the info useful.

 

cool, I'm on the way to buy it!!! lol Thanks for the heads up.
