The following graphs are with 9:1 2jz-ge compression, besides an upgraded headgasket and arp headstuds, it's a completely stock 2jz-ge engine. This TE-44 turbo was not bought from DaveH either, so it might be slightly different spec'd than the ones he gets...i'm thinking mine was possibly smaller?
Something interesting I noticed was the turbo spooled up ~400rpms later with the thicker supra TT headgasket. Fwiw, the turbo can spool faster than shown in these graphs, but the Greddy Profec B boost controller was set to spool the turbo later since my rev limit is raised.
The spool with supra TT headgasket is still very good, but the TE-44 is much better suited for a stock compression 2jz-ge engine where you don't have to boost so much to make the same power as seen on these graphs. At the higher boost levels, it begins to show signs of the "hot air blower" since it's such a small compressor turbo with is efficiency maxing out at these boost levels.
Also, this is on a manual transmission car (w/ lsd), so you dont get the benefit of that fast torque converter spool up that results in cooler air charge effect. So, my findings tell me either use this TE-44 on an automatic transmission setup AND/OR on a stock unopened 2JZ-GE engine (it's extremely fun with amazing powerband on stock compression 2jz-ge).
110 octane unleaded race gas is used and this is with AEM EMS pro-tuned by Justin Nenni of www.TuningConcepts.com.

The graph is jittery because of the intercooler pipes blowing off several times as well as vacuum hoses popping off and loosening. After I fixed those issues and did an oil change, the car ran much smoother and felt more powerful. I want more power on pump gas with the lower engine compression, so I've sold the te-44 with plans for a bigger turbo

I'm trying to sell off the rest of my other parts to help with the larger turbo upgrade and development costs for JackyPerformance products, so that's where I'm at these days.

dropped the clutch to see what the engagement problem was..this is what I found:

With the car in gear and clutch pedal fully pressed, it would start moving when the rpm's were revved to 4,000 and beyond.

How did you fix the problem with bolting in the speedo clip?
the last pic showed the holes not lining up....
I see a comment about "extended speedometer and reverse-light sensor wires"
but not sure how it will clip on just because the wires are extended...
thanks
