t2554 or t3 super 60?

This is my first untuned dyno run:

It's an impressive torque curve at 3000 rpm. I can't wait to see what it's like at 12psi properly tuned!

I would suggest you go with the T3, as there is just a much larger realm of upgradability with that. Upgrading from a GT25 would be much more costly and you might want to get a T3 flange. T3 60 is perfectly acceptable on the street, I think if you had trouble staying out of boost, it would get pretty annoying real quick as Stripes mentioned with his GT25.

It is a single cam. If you have more exhaust velocity you will spool quicker... take that for what its worth. Stroke, timing, head design, manifold design, and pretty much everything else about a motor will effect spool. Far to many variables to guess whether or not the Miata will spool the thing quicker or not I just posted it as some sort of comparison. And its the only 1.6 liter dyno plot that I have at my disposal that I actually have personal knowledge of the car and the conditions during the run.
This car was a pretty simple setup that was thrown together from crap we had laying around, so it is pretty similar to a potential diy Miata turbo setup. Just an AFC with MKIII Supra turbo 440s, an MSD timing retard thingamajig, a PTE 50 trim, and a cut down Ford Powerstroke IC. I think we were using a stock MKIV Supra turbo pump but I might be wrong. We lowered the compression with a GReddy gasket and used ARP headstuds, gave it 8.6/1 I think it was. Real simple crap.

no problem ike. Have fun. hepefully the weather will turn around for you. I talked to corky yesterday to get some ideas. I think the t3 is more my style. the t25 is probably more daily drivable and i will be doing some autocrossing, but i really like the holy crap feeling as a turbo spools up. Thats the main reason i didnt love the supercharger. i miss the way my twin turbo rx7 felt. Plus stephanie is talking some junk about her girly "princess" car being way more powerful/faster than mine. I cant have that. Hahaha. thanks for the help everyone. and as a bonus, the t3 seems to be cheaper. Its hard to find a bigger value monger than myself.

all this talk of T3's is making me wish i could realistically use my turbo with the AVO set up. Really though somone take this before I seriously concider getting a adapter plate made and a custom Down Pipe made to fit the t3!
I want to do it yeat at the same time I really would rather not have to think about all of the possible modifications I would have to make considering it will move the turbo possibly making it too close to the subframe and making the IC piping not match up right.

This turbo is very nice for the cheap DIY´er.
Dynojet, 12 psi falling to 11 psi.

Call me 210-379-5374. It was run for a short time. The turbine blade got nicked but the turbo is VERY servicable and its damn near brand new. It had less than 100 miles put on it. I'll guarantee it for 90 days provided it is properly fed with oil.
