im planning on getting a jdm d15b from homotorsonline.com, and i got couple questions. my car now has the d15b7, and i basically know the bottom of the d15b is a z1(vx) and the top is a z6(ex/si)

1)if the bottom is a vx, arent the pistons comin with a dish? im thinking use my old d15b7 flat tops to put my compression up. possibility? after all they are both 1.5's but i searched and came to the conclusion its going to go over the deck??

2)lsd tranny...when i look at hmotorsonline.com, they have the option of the tranny for 150 and the lsd for 300. is the lsd for 300 plus the 150 for the tranny? putting the lsd tranny for 450$$.

not clear about the pistons, but pretty sure that the lsd is only 300 dollars extra.

i was also thinking about gettin this swap, but i want the bigger displacement of the d16z6

Just because the bottom end is a 1.5, doesn't mean it has the same parts as the ultra econo US VX.

 

im just thinking out loud. i figure if everyone is saying the d15b comes pretty much as a vx bottom with a vtec head, the pistons will probabli the dished vx's. am i wrong, either way im planning to slap in my d15b7 flat tops. my only concern is if its possible? are the pistons goina be kissing the head?

and the lsd tranny. so hmotorsonline.com will sell me the d15b with the lsd tranny for a total of $735 + s/h? i dont want it to be them selling me a motor and the lsd assembly onli. i need the trany more then the lsd.

 

i heard that supposedly the d15b has practically Z6 rods at 137mm with small end journals like the VX. also using somewhat Z6 pistons with a higher placed pin so it will clear the head.......
