gqssb or 38r

Im looking to get a new turbo in the next couple months and my options are: gqssb or 38r. Each has their pros and cons. Wondering what people who have run them suggest. Here is what im working with. 2000 F250 Next week installing 238cc 100% injectors, Forged Rods, AFE StageII, MBRP 5" turbo back, TS 6pos Full Force tunes, Edge CTS to monitor.
I was wondering if the gqssb would have a faster spool than the 38r with the injectors? I know i am pushing the limit with the 38r, but will it clean it up good when at 100hp on the chip? Would it run too hot? What would you pick for your turbo if you were running this setup?
thanks

the gqssb is gonna be better but its gonna be double the cost as well. 38r with a 1.15 would be fine but if it was me and my money i would get a t4 with a s366 from irate. i'm pretty sure that full force doesn't tune either, might use jonathan at beans since they are right down the street

Ok, those are both good/great turbos, but what about a direct bolt on replacement turbo? Been a couple years sence i owned a ford. The d66 still a good bolt in replacement turbo?

The drop in for a 02 is the 38r.

The 38r with the 1.15 will run you just short of $1,900 and the S366 will run $2,100 and is far superior. Better way to go IMO.

38R is about $1300 the 1.15 housing is about $300 if you need it. While there are better turbo's, it's hard to beat the price especially if your staying under 500hp.

Yeah I am probably going to go with a 38r I am Looking to stay about 425-500 hp. I do not want to go any higher. Its my daily driver I need new injectors so I figured do it once do it right, have the power there if I want it if not tune it down. My main concern is fuel milage. I'm getting about 15-16 avg city in cold Ohio on winter fuel. The 38r should be able to spool super quick with those large injectors right? Also heard I need a turbo timer for it. Would you recommend. This setup should be night and day difference between stock injectors and turbo or else not worth it for me. All answers appreciated. Thanks guys
