Just to review, you're running a z24 with z18 turbo and manifold and z22 fuel injection?
No, its a complete Z20E with a ka24e turbo manifold(ebay spechulz) and a RB25DET turbo.
I did initially swap a Z24 in it with the Z20 fuel injection on it but the valve seals blew after a week of running so in went the Z20.
I do have a Z24 i'm rebuilding at the moment though with wiseco forged pistons and a cometic mls head gasket and ported head which will be swapped in sometime this coming summer. I'm gonna run 14psi of boost through the stock Z20E first and see if it copes
