I recently bought a car that was running a D15B Vtec i had a rod shatter and can't find a replacement rod also it's running PM3 pistons/rods can i put my head onto a d16z6 and have it run and will it be worth it? or should i swap the d16z6 pistons/rods into my d15 block since they are the correct length? won't the d16z6 block with my d15b vtec head put out more power since it's a larger displacement?

 

Just get a z6 block or a sohc zc block and slap the head on it

 

which "jdm d15b vtec" motor do you have? most of the vtec d15bs i have come across have the same po8 head as the z6 motor.

 

the d15b vtec rod is the exact same rod as the z6 and y8. basically the big journal 1.6 D series rod.

as far as the pistons, they are customs pistons. they have the wrist pin moved up a bit to house the longer rod.

the block is a D15 block. or a Z1 block. you just need to use the actual d15b or Z1 crank to run the d15b vtec rods/[piston combo.

also the d15b(non multi stage vtec one, more or less the obd1 engine) head is the same as a z6 just with a slightly larger cam.

 

Or just find a 1.6 block and call it a day

 

Get a d16a6 or d16y7 block for best results

 

the d15b block has a rod ratio similar to that of a b16b or a b16a. its a nice stout oem D series bottom that can handle alot

 

i ended up just getting a z6 block and putting my head on it. since it's the P08 head will i just time it as if it's a z6 or change it up a bit since it's a different cam?

 

Anyone else done this swap?

 

what swap are you talking about? the d15b head is the same as a z6. well the casting least is a " p08"
