Thank you for sharing, have been following from the get-go. Set up looks great, can't wait for feedback once you have had some time to do some shakedowns....Thank you for sharing all your progress on the forum, it is much appreciated on my end.

Thanks for the kind words, everyone!:D
No. I'm taping a pressure gauge to the windscreen for the shakedown, but I am awaiting the arrival of my Profec E-01 so that I can control the E-Manage and boost all at the same time. It has a wonderful "virtual" boost gauge and a bunch of other goodies and looks really cool. It will go nicely with the other piece piece of frivolous eye-candy I got - an HKS SSq BOV.

Congrats for being one of the most informative forum members to date on the Turbo project
Do you anticipate any Turbo lag and if so in what rpm range ?
When you increase the boost from 6psi to the 9psi when you add the extra injectors and the bigger Turbo that you mentioned in an earlier post how much HP do you hope to achieve .?
cheers

Well, having driven the car around today (about 20 miles) I can say for sure that there is NO turbo lag with the unit I am using. :p
In fact, it is attempting to produce boost at part throttle - you can hear it zizzing away under the slightest accelleration.
Just for grins, I got into it once or twice at 2500 RPM and there was already 3 PSI (which is where I have the wastegate set). I won't be able to do more boost until my Profec gets here on Friday. I'll be in Miami until then anyway...
I think that I will ultimately need a bigger A/R on the turbine side to keep the thing from stressing itself to death.

Thats funny I did a Google search and found the .45 ACP rounds, but I thought it was just a similar name, so I added +turbo, and stuff. I finally gave up and posted the question LOL :p

Awesome, Jeff! Glad you got it in one piece and running!
I REALLY like the work on the manifold heat shield. I've half-*** made manifold heat shields before, and I really like that technique - that's going into my bag 'o tricks
.
I would seriously look at getting a regular boost gauge. The E-01's screen is, to put it plainly, lousy. If you don't already have the boost sensor for the E-manage, you can buy the Greddy 60mm peak/hold boost gauge and share the sensor - it's the same sensor. Anyhow, I had the E-01 on my old 10th Anniversary and was really disappointed with the screen. The rest of the unit is mighty kickass, though. Lighting really sucks on it - if you ever used an old Palm Pilot with the greenish glow backlight, it's IDENTICAL.
If you're sticking to the budget, you can get a 60mm Greddy mechanical boost gauge for just under $100.
Good thing is the E-manage was originally designed to add fuel control to a non-turbo car when going turbo, so it will work very well for your application. It will take some careful tuning, that's for sure!

Jeff: I printed out the exhaust manifold template. The exhaust ports on that template are HUGE. They aren't that big coming out of the engine. Maybe the manifold or the gasket are that large but not the engine. You wouldn't happen to know the actual sizes out of the block would you?

I'll check against the old gasket to see if there is a "dirty" area that etrays the true port size, but IIRC they were actually that size as they exited the motor. The individual runners very quickly get constricted in the OEM manifold - down to half the size of the actual ports. That tracing, however, does show the actual mating port size.
I'm in Miami at the moment, so I will try to get better info on Sunday.

Couple of quick questions:
1) Does it free rev to red line or does it cut out at a lower rev level.
2) Does your engine light stay on
3) Any side effects from the install yet?
I have had a couple o issues with a product I am looking at and am curious if you have had any hassles.
Thanks,
Gibbo.
