whats going on guys i have a d15b1 and i was wondering if the d15z1 vtec-e head swap is any good with the d15b1 block because i have the head just laying here and i want a little bit more power then the puney d15b1 with 70 hp lol

 

Play with a compression calculator (in the FAQ) and see what that combo will get you. I'd imagine it would be high considering the combustion chamber volume of the Z1. If I had anything worth saying to you, hold off on any notion of any swap/conversion until AFTER you have completed a MPFI conversion. This is the key to upgrading to anything and everything else later on down the road. Get that MPFI in and running properly then start thinking about what you want to do.

 

Still not gonna be quick. Its an eco head. I wouldn't mess with unless u plan on getting better gas mileage.

 

Don't use anything d15z1 use a d16z6 head

 

the z1 head is the best head change the camshaft and rocker assmbly to z6 ur comp ratio would be about 10.5.1 best head to use cause of the small combustion chamber

 

my setup is sohc zc with z1 head with z6 internals never been dynod just street tuned butt dyno says about 160 at the wheels i walk all over ls integras at the track best time is13.2 will have pics up asap

 

If you decide you don't want it I have an A6 head with less than 2kmi. Id be willing to trade..

 

Im looking for z1 exhaust manifold if anyone has one that they want to sell let me know.

 

Planning on doing the same thing. I have a vx and the engine is burning crazy oil. I was originally planning on a full rebuild but came across a mint d15b1 and long story short i figured that i can use the block and swap the head and everything should be good. Im not looking for a sport monster just a reliable motor. Just looking for possible problems that i should expect, maybe this isnt even possible. Thanks guys.

 

They will physically bolt together but the piston tops are different (as is the stroke of the crankshaft and rod length). Not sure how this will effect things or if that's even your intention.

 

I figured that as much. I should hope that the engine will still turn and run. Planning on starting this thing next week end. We shall see how it goes. Any other advice or heads up would be appreciated. Thanks again.
