Looking good

that's surprisingly tidy. what are you doing about the AC line?

also, move up the IC if possible so that it has room for airflow out the back.

I'm not sure yet on the AC line, I may have to have it custom made once everything for the turbo is in place. There's a good amount of room behind the IC, so with a fan mounted to it I think I can get some decent airflow. It'll be warm engine bay air, but still probably better than nothing... maybe?

Actually come to think of it, not having to mess with an IC would make this much easier. How necessary is an IC on a system that's only putting out like 8psi?

my old datsun 280zxt ran 14lbs boost on an otherwise stock engine configuration, which had no intercooler...

I don't think there is a cooler project... Great work, love the OEM!

[Mr. Tasty]

what about eliminating the intercooler and introducing water or water/meth injection after turbo?

TCD stage 1 turbo kit does not use an intercooler. I believe it is in 7-8 psi range.

My supercharged m20 is about 9psi and it's not intercooled. It's extra kickass in the winter. I do notice it pulling timing in the summer.

You already got the intercooler. Why not run without it. If you don't like how it runs, figure out a way to install it.

[IronFreak]

I've seen plenty of domestic turbo builds without intercoolers. especially at no more than 8psi. like mentioned above, hit that with a meth kit and you'd be golden.

As far as the BBQ paint, I've yet to find any paint that will hold up to NA exhaust temps for more then a few months. If someone had a better solution, let me know.

Mines been holding up fine, but I also threw it in the oven like the OP.

keep on tinkering...

THIS!

I'd keep the intercooler because you know if 8 psi is good, then 10+ psi will be better. Keep it up!

I remember this car from the Dyno Day at the shop in Portland a few years back. My old ETA put a thundering 90whp down that day :rofl:

I remember you were upset about the numbers your car put down compared with the other M30 car(s). Im sure that exhaust had something to do with it. Do it right this time!

Yes, it was way down on power. I think most of that had to do with the Miller system not being tuned well (I used there off-the-shelf 91 octane tune). With the old AFM re-installed and a new ssquid tuning chip, it pulls harder than ever. My challenge now is to decide whether to run the turbo with the Miller setup or go Megasquirt... I know everyone will say MS, but considering I already have the Miller stuff, it's a matter of free vs $$$.

keep up the great work!

I just realized your running AC. How come? Would removing it make life much easier?

Do you really not know the answer to this question ?

lol I do. But I was wondering why since most people that run turbos remove them first thing to save weight and make life easier for doing the piping. I worded that all wrong made me sound like a dumbass.
