- Thu Nov 05, 2009 8:50 pm #154989 The HX ecu is what you will need to control the vtec-e operation of the y5 head, and it is only 96-00 (obd2). Or will the VX ecu work?

Why not use a z6 head with a p28 ecu chipped? That would probably be easier to setup and make more power.

You didn't mention which rods, but I would go aftermarket as the d16z6 is not much thicker than the d15z1.

I'm not that familiar with the d15z1 block... is it worth boosting compared to a D16z6, or is it more like the JDM D15b or the US D15b7?

- Fri Nov 06, 2009 2:10 am #155022 The d15z1 already has low compression pistons, Making it a good canidate for boost. You can put in LS(B18a/B18b) Rods which are good until 300hp, Keep your Low compression z1 pistons and just use a D16z6 head.

You will have to make some bushings machined, or use oversized bearings to shim up the LS Rods to the D15 Crank.

Assuming you hide the turbo it would be super sleeper status if you had a "VTEC-E" Valve Cover.

That is the build I was planning on using a d15z1 block. The D15z1 is its own engine. it has the smaller rod journals of the D15's however the stroke of the d16. Giving it the potential for some torque. :hehe:
