This is the third DIY kit I've built for my '02 Z28. I used a Holset H1E for this build. The stock manifolds are being used right now, but I plan to switch to truck manifolds and 317 heads soon.

A DIY alky injection system turns on at 3psi for intercooling, and tuning is done with HPtuners. I can't get on it right now because I don't have a WB o2 set up yet. I've got the timing pulled way back, and I have fattened it up under PE. I don't see any KR under the light boost. I'm pretty sure I'm safe, but I don't want to take a chance.

I built a frame for my radiator to sit upright and lower. I also relocated the battery to the back. Those mods made plenty of room for the turbo to sit in the engine bay.

I drove round trip 600+ miles to Vegas and back two days after the install and didn't get into to it at all. The most I saw was 3psi at part throttle going up grades. The boost starts to build around 2K RPM and comes in at part throttle.

I can't wait to get my WB so I can tune the AFR and open it up.

 

how much boost are u expecting to run? i think you need to get an intercooler, all due respect, but i believe all seriouse blown engines need an intercooler to run efficently. Nice build quality though.

 

So your in Memphis, lol Any fast cars down there??? I'm about an 1. hours away.
I might come down there racing sometime , when the car gets done

 

I agree on the intercooler. Alky for now until I get more project $$$.
The plan is 7psi. Maybe some 317 heads later, then 10 or 15.

 

I need to change that. I'm in So Cal now. No fast cars here either.

 

Nice work.

 

Thank you!

 

I'm curious if you have overheating problems while sitting in traffic with that setup.
