Precision Turbo PT6766 compared to the Ebay T70 + installation and tuning
I just recieved my new Precision turbo
Billet Wheel 505-6766 with .96 A/R and T4 flange. It is a work of ART!
This thing spools up instantly and stays spooled longer than my ebay T70
ever dreamed of. The ebay turbo held up
great for 11k miles but it never responded like the new Precision does.
Now I'm working out the bugs in the car to take advantage of the new-found
air supply. I had to greatly increase fueling at all Boost levels to get the AFR back down to 10.9.
And the sound of this thing is nothing short of amazing!
Engine is a stock (polished) tpi intake, mildly ported L98 aluminum heads,
8.6:1 cmpression, 224/224 @ .050" hydraulic roller comp cams custom grind
and SRP -24cc dish pistons.

Installing an eBay 20g
I'm reviewing an ebay 20g TD05 internally-gated turbocharger. You've seen me open it, assess it,
and port it. Now I'm going to install it and see how it fits on my car.
Its dimensions are close enough to a Mitsubishi turbo that it fits well, but it didn't play nice
with my aftermarket stuff as the video illustrates.
You'll see what I mean...
The wastegate actuator nipple aims straight toward the compressor housing,
and I don't like it. I fixed it with a pair of pliers and an allen wrench
at 5:55 in a way that's far less likely to break it. The flanges and bolt
centers lined up fine and without any issues, though others have claimed to
have had them with this turbo. The
compressor cover is an obvious giveaway regarding identifying this turbo. It does not wear the cast-in designation
TD05H that the Mitsubishi turbos do, but
for $228, what do you expect?
If you chose to go this route, just manage your expectations. Be aware
that it might not bolt up perfectly to your particular car, and be willing
to fix what isn't perfect.
