Are you trying to put this on a vec c? If so its never been done (so far) as the ECU is different.

 

[turbo_larsson]

Yes on my GTS -03 with z22se

Going to attempt with z20net ecu as its easier to map. rushy

i hope it works out cos it will open up alot for the vectra c croud.

I've always wondered why it couldn't be done without NET ECU.

Never say never as they say, fingers crossed it goes to plan.

You should start a build thread turbo_larsson

Yes i will try at first with the Vectra C ECU if i can find someone who can program this.

But as a backup have got my self a loom/ecu from a realy early Vec C Z20NET.
Then i'm home free so to speak. Since this is no problem to program this ECU with a good program that works with the SC instead of a turbo.

After some cleaning i looks like there is a 3.0 on it. Must a stage three pulley then?

 

[evocarlos]

its just a zzp 3.0" pulley

 

[turbo_larsson]

Then i think i will try to change it back to a std one. To make this work easy on my Vec

 

[evocarlos]

the zzp one is hub based so all you have to do is unbolt that one and fit what ever size you want/need 3.1 is what i fitted and then had to have a massive rpm cap
the standard one is 3.3" and push on
