up...
anyone!!?

They are the exact same 75mm bore size, so yes the P29s will fit in the holes. I know on non-VTEC blocks the pistons actuallt sit too low in the cylinders, but I've heard that they work fine in the JDM VTEC D15B and VX D15Z1 VTEC-E blocks.

I have no clue on the compressin ratio though - I can only imagine it'd be something crazy.

I'd do some research on the D series message baord before commiting to any build, because honestly I'm not 100% sure they're a okie dokie piston for that engine.

im putting p29s in my d16z6 in about 3 weeks. im using stock rods and it came with rings. if you do have to buy rings seperately buy for a d16a1 outa a 1989 acura integra

Correct about the rings, but the question is still there about compatibility with a 1.5L block.

yes, actually i know some people around rocking those p29 pistons with d16 blocks..
thats why im asking if they will work/fit fine on a d15b vtec block

btw.. thanks for the tip of the rings...

Ahh yes the P29s are great - I know:





I've been driving my D16A6 with P29s in my daily driver for over 4-5 years now with zero issues. I just compression tested it the other day and it was a solid 250psi across all 4 cylinders!

wow..
that ones looks great...
love the work on the block ahaha

im asking about this, cause i own a jdm d15b vtec engine..
just looking information if the p29 pistons fits well with the d15b block and head...

Nice photos. Did you do any work on them to remove sharp edges (e.g., around the valve reliefs), or is that the way they come from Honda?

They came out of the boxes like that.

anybody, real sure about this??

another question for you guys... is the d15b vtec head the same as the d16z6 one?

I again can vouch for the P29's in a 1.6L block but I haven't the first clue about 1.5L.... Check bore size!!

chadalac1712

yes it will work...just use your stock rods and you will be fine...you will have alittle lower compression...almost same as a type-r 11:5 instead of 12:6 in the z6 block...also z6 rods and stuff will work....lemme know bc i got brand new 1's with rings and everything fs...1 needs a new rod bc it was bad but the pistons are brand new...already mounted on 3 pistons
