i also have a vx ,If u change the head and ecu will u still have to run a 5wire o2?Or do u run a 4wire?cause my 02 is stuffed and it would work out better if i can run a 4 wire.

p.s also what head d15b or d16z1

 

I'm assuming you mean D16Z6 (92-95 civic ex/si). The d15b and d16z6 are the same exact head. All a d15b is is a d16z6 head on a vx bottom end. However, I've heard that the JDM d15b uses a wilder cam than the US Spec D16z6

 

sorry forgot to note im from australia ,we have d16z1 in stead of z6.But anyway any body done one of these conversions??I can get a head +ecu+wirring for the price of a 5wire 02.Any idea if my compression will change for a swap like this?vtec-e has really been buggin me cause it feels like a non vtec doesnt rev and makes power down low rather than up top.How do vtec sohc feel in vtec do u feel it lock in or is it like my vtec-e.

I bought a vtec before i new of vtec-e if i could turn back time i wouldnt have bought one of the slowest civics made.
