Now that the forum is back, and I have moved onto my 2nd shell I feel it is time to post this. I picked up this shell 5.5 years ago and have been moving things over from my white 89.
Here is the 1jz/holset swapped in:

Nice!
Have you driven it with the new turbo?
Mid build I moved from CT to GA, car is still at the shop in GA. Once it gets here, it leaves (again) to go over to Evolved Tuning for a tune on the ECUMaster. Its limping along on the stock ecu right now.

The interior is all installed now.

The downpipe had to be cut and fit, and there is a cat on the car now. The shop said it idles as quiet as stock, from what I heard on the phone that is about right.

The new wheel installed:

Harness bar test fit:

I am removing the harness bar though, I don't like the lack of security when its bolted in. I will need to have some sort of spacer made or something, it doesnt sit right with the interior plastics in.

The car goes into Evolved for a tune next week, lets see what it makes at ~16psi.

Smooth curve, shocked that it made so much torque. Going to need to eventually get that boost controller hooked up so I can ramp in boost earlier, its just a little lazy.

That should be a lot of fun. What did you do with the Holset?
I was low 400s with the holset, but that was at 18-19psi. It spooled entirely too quickly (was seeing full boost at like 2400 rpm) and I eventually want to get some cams and rev out to around 8k.

I like those numbers for what I'm aiming for in a daily driver, I think I'll send my Holset out to be rebuilt and run it.

Which holset do you have? I had a HX35w with the BEP .70 T3 housing. Lightning quick spool and it held 19psi to redline. Based on the fuel I was pulling, I was in the low 400s.
