They have different size compressor wheels so yes.

Yeah proper garrett gtxs do but you can get a billet version of the 61.4mm wheel to suit the standard housing or a proper gtx3582r comp housing

Got it all together today. 

 

It is going through the stock crossover for now. 

 

I used some 2.5 inch ally pipe I had lying around from the turbo to the hotside of the cooler. 

 

It is quieter when spooling and flutters less when backing off than the stock turbo. 

 

I'm running 12 psi until 3k rpm then 15 till 4500 then 17 from there. This is to help with grip as well as to look after the driveline. I'll turn it up a bit more tomorrow and see how it goes. 

 

It does go a fair bit better than the stock turbo and doesn't fall over up top like it used to. 

 

All in all it what I was expecting. In saying that I wouldn't have done this upgrade if my turbo wasn't already stuffed. I need moar powah lol. 

 

It suits my car however as the internals and driveline are stock for now.

Currently looking into a new car, saw an FG-X running a GT3582r, unspecified injectors (one would assume 1000cc), Venom cat, stage one Process West cooler and Herrod air box (what gains there are there I don't know, maybe someone does). This is the sheet, and if it looks okay I'd rather getting something that's had the money and effort spent already. Reading this thread points to the GTX variant being better in all practical ways, but would this setup be fine as a daily? I read the GT will have higher-end punch, handy for the long overtakes I tend to do, but at the same time I don't want to be chugging away on takeoff. I don't do drags or racing so launch isn't important so long as I'm not digging up the road. And is that Nm figure right? Seems very high or I'm misreading it; the last thing I want is a ZF rebuild. Sorry for the dumb questions/assumptions!

There is two torque figures on a dyno graph, one is "torque" and the other is "derived torque". The only one that we care about is the "derived torque" figure. 

 

The GT variant is perfectly fine for a daily vehicle and has plenty of room for power uprages for a stock turbo, especially fine for the power shown on that dyno graph.
