Hey Everyone. I know your going to ask the question, why bother, but what would be the best head to swap on a D15B8 block? I am going to try and see how many ponies i can pull out of the old engine. I know its only pushin 70hp, but i got lots of faith in myself. Thanks!

 

The problem you're going to run into is that the pistons are only notched for an 8 valve head. Onless you slap in different pistons, you can't even put a B7 head on it, or a vtec head for that matter. If you do put the other pistons in, you could throw no a b7 head and get a crx si cam, or just throw a z6 head on... Worth it? not really. You'd spend more time and money than if you just slapped a d16z6 in it to begin with...

 

say i slap diff pistons in it, what should i get?

 

honestly, I'm not sure if all D pistons are the same, but any other 1.5l should work dandy, as long as it's a 16 valve. D15b7 being the closest donor.

 

so, do you think it would be possible to swap a B18B head onto the old little 1.5 without a machine shop?

 

No B head will fit any D block, or vice verse. If you make it work, I'll let my mom give you head. Plain and simple, can't be done without a ton of money... which you don't have, or else you wouldn't be thinking of keeping your d15...

 

They CX pistons will work with The DX head. I ahve done this and have not really ran into any problem. So for that only one is a CEL that wont go away. But if u up grade to the DX head you should upgrade the IM and the EH. The CX is tiny.

 

does your mom know about this..


just save up more money and get the right motor in the form of a B16 or B18
