Heh, I'm not up on turbo speak at all. It was cranking on my 331 notch. It did 15 psi easily. With street tires, stomping down at anything less than 70 mph was a lost cause. Instant sideways. The intake A/R is .60, exhaust is .81

Check my gallery. There are three pics in there.

 

i got a turbo for ya, its a TA-49, ill sell it for $200

needs a re-build, i got a guy lined up for the rebuild as they are hard to find for this turbo. but pm me if your interested

also, i suppose i could throw in my intercooler for the right price...

 

What brand is this? sounds like a Precision with the integral waste gate am I correct? A lot of GN's run the ta-49 I think has a 58 0r 60mm wheel if I recall.

 

lol, close, its a garrett.

.63 trim exhaust and .60 trim compressor, journal bearing, integral wastegate, but it runs better with an external wastegate

 

Nice turbo....like I said very popular in the Grand National world. Very street friendly and spools fast on a small motor. Intergral wastgate works great you just have to port the hole to about the same size as the puck in the down pipe. I had a T66 on mine same .63 turbine

 

like i said though, the hard part is finding a rebuild kit, i only found 1 guy in arizona with the kits for $105
