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.

Just an estimate of where a turbod16
with an ebay turbo will spool at.

Porting an eBay 20g turbocharger
The price of this turbo will make it a
popular purchase, so I figured I'd air out some tech about ways to improve
it. This thing is not for everybody. I wouldn't feel comfortable bolting
it on my car the way it comes out of the box. I could complain about its
flaws except that so far absolutely none of them have been a deal-breaker
for me. To me it's like an empty canvas. I promise to eat those words if
it happens, and share my poop. Usually I can easily correct these flaws
myself and so can you.
If this thing turns out to perform well with what I do to it... It could
easily be a cheap, quick ticket to an 11-second car. Something you could
do with a free running 1g, a hacksaw, and about $500 worth of fuel
upgrades. Yeah, that would be ridiculous, and I'm bolting it onto a
well-modified car... But that being possible speaks volumes for what a DSM
can really do.
This is no big deal to me. I'd rather guinea pig my car for you in HD so
you guys can decide whether or not you'd spend your money on this. Really
it's an experiment because this isn't my daily-driver, and it contributes
to building a better Colt.
Tools I used involve:
Milwaukee model ???? 1/4" straight-shaft electric DIY grinder
Cone and ball-shaped double-cut burs
180 grit high-speed flap wheel
Dremel with a flex-shaft and a tiny 320-grit flap wheel
a zip tie
10mm combination wrench
tiny flat-blade screwdriver (00) for the e-clip on the wastegate
Turbocharged Grand AM PT.2
Video/pic collage of my turbo ga...most
of this you may have already seen, just so you can hear my car unlike the
first video I made... currently down rebuilding transmission and doing
valves and valve springs atm, checking pistons/rings/ doing bearings on
bottom end and whatnot possibly stage 3 turbo cam.
1984 El Camino Single Ebay Turbo 327 first start and drive 1080p hi-def
A friend of mine just got his single turbo El Camino project running and he is about to
become addicted to turbos. Engine is a
327 with Sportmans II iron heads, one piece Holley 600 blow-thru. He used
ebay turbo headers and a late model full
size chevy truck Y pipe to make a great looking setup. It's not dialed in
yet and way too rich, but it still ran strong for the first run. Lots of
Ebay parts here and he has under $1000 in the whole turbo project.
Twincharged GTP Running 12psi
My Twincharged GTP Running 12 psi (About 400hp) on the new engine and
tranny...... Not as strong as 17psi (500hp) but still feels good !!! This
is without the bypass valve. It's less laggy this way...
