I had the GT3076R on a 2.2 motor, it start spooling @ around 2200..

I just bought the GTX 3582, among many other items. Going for tune tomorrow...the specs are nice and something different from what the crowd is using.

I have the GTX3071R but havent gotten it installed yet... time is a mother. If you want the quickest spool the 71 is probably the better bet and you can still upgrade the A/R housing bigger if you are ever concerned with it choking up the compressor. I have the 71R with a .94A/R rather than the .73 that ETS mentioned was a limiter.

A lot of guys aren't using them probably due to the fact that swapping to a non stock frame turbo results in needing a new exhaust manifold and downpipe. Some might not want to put that money out especially if they've already bought aftermarket ones for their stock turbo.

Actually the GTX3071r is offered in a stock style frame.

True I forgot about that.

I got it, just haven't installed it...and since it's wintertime I probably won't install it until next year or sell it.

. . . . . I wish there were more people like you. Buying brand new items and selling them on the forums at a loss.

The problem with the stock frame Garrett turbochargers is the turbine housing. They are just too small to flow the numbers advertised by Garrett.

I don't really look at .94 as being small? Not trying to dispute, just curious what you meant... maybe that 500hp on a .73 is having too high of an expectation?

It's an Area Ratio is what that number means.

T3 .82 A/R and T4 .84 A/R are no where near the same sizes even though they are only .02 apart.

Since this is not a t3 or t4 flange and even smaller, the actual turbine housing is much smaller.

I dont think you meant 2200. That is pretty quick for that turbo to spool. Because even the JB stocker doesn't spool that fast and it flows 42lbs/min.

back from the dead, so what about a non stock frame garret dbb gt3071r? curious because thats what I have. I should be heading to english racing soon to get it tuned.....running the 3071r with ams intake/exhaust mannys 4" turbo inlet side with full 3" exhaust gscs2 cams springs, retainers and 1mm oversized valves...and supporting fuel mods....im stuck with 92 octane where I live.

MotoIQ just did a good article of this turbo on their project Evo X.

Here is the link: http://www.motoiq.com/magazine_artic...-cosworth.aspx

nice article. I made 425 w/o the cams or manifold so there's definitely a lot more in this turbo than what the article suggests I think. Guessing its because they're tapering down almost 8 psi where they're reading the power? I think I was around 22-23 at that point. Wish I had a lift when I did this... something as simple as rebolting the oil lines pissed me off.
