What size Turbo for 925 Big Bore

[Fordmancat]

I am doing a big bore turbo and am wondering what what size of turbo I should run as a race gas kit. I will be running AV gas and don't want it to be laggy.
I ran a 2860 on the stock m8 motor.

Im sure youll get lots o answers,especially with all the turbo size debate threads going on right now Did you talk to your original kit builder?

I understand there are some quirks to making a 925 work good off the bottom, so there may be more to it than just sizing a turbo. Based on my own experiences with a M7/1000 big bore and now a stock bore 800, Im guessing you will be in the gt2871, 2876, or even , 3071 range. There are so many flavors within each size range that it gets to be a worry. If you liked your 2860, then the correctly configured 2871 might be the safe bet. Ive had great help from OVS, but there are other turbo gurus who will prolly steer you the right direction. Give em a call.

2876 works really well

I used to run a d&d 901 with 2860

I would recommend a 2871 with a 925

I have run a 3071 and a 2876 and the 2876 runs better bottom to top.
So Far.
May try somthing different this year.

If anyone has any clutching recommendations or Boondocker fuel numbers for me to start with; that would be great.

What ar on the exhaust and compressor side of the 3071?
Did they run the same wastegate system?
Any other changes made when turbo's were swapped(stinger size, exhaust housings, air intake, etc)?
