Hello all,

This is my first post and I am just getting into the Honda motors, so please forgive any stupid questions.

After rebuilding the head of my D15B7 (3 angle valve job, port, polish, Blah, Blah, Blah) I found that the pressure on the cylinders has begun to suck oil past the rings. So, I bought a D15B7 short block to prep and found that it has a bent rod. Though, there is no damage on the top of the piston to indicate any contact causing the bent rod.

I have been told that a D15B7 rod is the same as the D16Z6 rod. Is this true? Where is the best place to buy a set of rods (not high end, just stock replacement or used)? What pistons will work in the D15B7? I believe the bore is 75mm (please correct me if I am wrong), but are there other pistons from, say, the D16 that will work? What is the max overbore on a D15? I would like to bore/hone the block and put a new set of pistons/rings in and have it ready for the head I already reworked.

I don't want to build a bunch of horspower with the D15B7 (I have a B16-DOHC for that), I just want a good running engine? Is there any advice here? I have been doing engines for a long time, but this is my first Honda engine. Do I need a block guard? Any other info would be appreciated.

Thanks,
Marc

yes the b2 rods will work but i believe they are the weakest d-series rods and would not be good for building for big horsepower.

i'm almost positive the d16 rods will NOT work, but i don't know shit about your motor... IIRC; d15 have shorter rods (resulting in less stroke, and ultimately less displacement....) bore should be 75mm tho (same as d16)

d16 rods have different sized big ends, and different lengths.. (134 vs 136, IIRC?) if you want a stout 1.5 liter bottom end, find a JDM D15B crank or bottom end, and then you can use the D16 rods..

Crower makes rods for the D15B7 engine that fit right in. I picked up a second hand set for $360 shipped :) Just got them in the mail yesterday and they look great. I'm pretty excited about getting this thing together... pulling the engine out in the next few days.
