d15z1 turbo
 

Hey ya'll. Obviously I'm a noob. I have a question about turboing a d15z1 out of a 94 vx civic. I did a search and found some responses for different setups and such. My question is..... should I do it? I have no way of knowing if the people that have posted before are turbo gods or not. I am fairly new to turbos. With the vtec-e am I in for a pain in the ass? As for now I have a completely stock internals d15z1. I know a new tranny will help with getup and go. Does anyone have any experience boosting this engine?? Thanks!

Vote for Stealthmode/boost and we'll tell you

anyone else?

Re: d15z1 turbo
 

none of the programs support the vtec-e as far as fuel management.

if you used a p28 you could gross over to vtec but youd only be using 2 or the 3 available profiles in that heads configuration

Re: d15z1 turbo
 

Is the z1 the 3 stage vtec-e? I don't know much about that ----. But I a'm using a y5 head controlled with a P28/Uber and it works flawlessly.

Re: d15z1 turbo
 

y5 would be the hx engine i think right??

yeah it is possible

Re: d15z1 turbo
 

Yea, '96-'00 HX indeed

Re: d15z1 turbo
 

So ya'll are suggesting a head and ecu change. Once I do that, will I be able to live with it N/A for a while? I've heard the compression ratio goes down horribly low, becuase of the dished piston on the z1. I dont have the scratch to be able to afford everything in one fell swoop. So should I wait and do everything at once?

Re: d15z1 turbo
 

I'm not sure which EMS he's using but there's a guy on Honda-Tech with a VX turbo.

He even kept the same tranny with super long gears.

I'll see if I can find his project thread so you can ask him about the setup. I've only seen one VX turbo, so it's pretty rare.

I PMed Built B16a on H-T. I'm trying to get as many resources as possible. His vx is badass. I got some inspiration from that. Thanks for the help!
