So, this is my first real posty, and I wanted to open with a question. Of course. I've been bouncing around here looking for info on the GT series and what people have been using, and comparable Turbonetics options, and any other options. I have been seriously considering a GT2860RS big trim for an upgrade. I've read and been told that while its a good turbo, it shows I'm indecisive, since its an in-between of either big power or fast spool, and some say go up or down, I guess. Well, I think a 300-340 hp limit is fine for me, and I'd probably start by shooting for 250-280 before head work and other non-bolt on stuff. Also, I would like to know about upgrading the IHI or a turbonetics option instead. So, what I guess I've got GT2560, Gt2860rs, GT2871r, T-type, IHI Upgrade as questions. Of course with all of this I'll be going FM intake, FM downpipe, FM intercooler, O2 signal Modifier for a while, with a 034 Megasquirt 11b ecu eventually. Not sure about exhaust yet,but don't care much. Other crap I'll be doing would include ENkei RPF1 16x8's w/T1R's, Frog arms and FM frame rails, 3.636 rear end.
Boost plans are to start at 9, 12 at most before standalone, 12-15 with standalone. And power goals are to start at 240 +/- 20 without standalone with driveability in mind, and 300+/- 20 after standalone, and go from there.

That's a bit to read.. huh?

there is also a recent dyno on here from Begi with a gt28rs on an '03 I think. Plenty of threads and dynos about the gt2560 also. Less people with your other options though I'm sure there are plenty that would love to see more on the gt2871r...

What are you plans for the car autox, drag racing, track ***** maybe a fun daily driver?? Exhaust manifold do you plan on using?

I would say the biggest factor is what you plan on doing with the car.

Track/ daily driver. I would absolutely LOVE to get into auto X again, but not with such a new car. As far as a drag track goes, I'll take it to get a few times, at most twice, and thats it, just to see, and to know. Preferably, I'd like a moderate track car that is very drivable on the street. I dunno if you guys are familiar with the MSM but it has a lot of drivability issues out of the box. FM solves most of these for less than a grand, minus a standalone, so thats good.
On another note, I did find exactly what I want for now, I think I'll be going with the IHI upgrade since its the right price, until I get sick of it and want more, I think I'll move to a potato, needing a new manifold and Intercooler. I can make 230 or so with the blouch setup. that should give me an idea of where to go next. Sounds, compromising huh...
