I don't know how many other people realize how expensive it is to buy and then build a B series motor these days. But I do not make enough money to be able to spend the 3,000 to get a new motor and then another 1500 to build it, and then another 1,500-3,000 to turbo it. So I am going to work with what I got. I have a '92 Vx hatch. But I am beginning to think the D15Z1 motor is a One-off type of thing. I mean its got the stroke of a D15 with the rods of a D16 (good for rod-to-stroke ratio) and then the pistons have a -7mm dome to make the compression 9.3:1? No one anywhere makes pistons for this motor. So I am going to have to get them custom made. But I don't know how to calculate the head volume. If anyone is planning to build a D series I can tell you where to go to get your parts for really good prices. and if anyone knows how to get the head volume please help.

 

beat ya to it, there are a few of us on here with some built *** d series engines,

me, ghettoturbo, stealthmode

 

i would go with a d16z6 (sohc vtec) man... they're only $250-350 and it's so many people giving away parts (especially pistons/rods)... will be way cheaper in the long run

 

agreed. the vx motor is a pos, my little brother has one.
