Gen 1 Turbo Size for ~250hp Kit Car

[nskyline34]

Have a Can-Am x3 UTV that I'm swapping a Hayabusa into for my YouTube channel, and I want to add a turbo to it eventually. But I'm starting to think that rather than do it later after I've already fabricated motor mounts and everything, that it might be wise to do it now so that I know it all fits and I dont have to redo as much later on.

I need something that will be quick spooling so its got as much bottom end torque as possible since the X3 weighs just a little more than a busa does.

I'm wondering what turbo specs the RCC 1 kit is or if there are charger specs that would work better for my application then I'd really appreciate the feedback? I was thinking something like this: Basically a GT2560 or GT25/GT28 hybrid turbo? Or...?

Sounds like a reasonable sized.
Not stupid. Leaves room to turn it up WHEN you want.
Still think a Davis or RCC. Saves so many possible mistakes that I made ALL.

Honestly this is for a youtube channel, so the more budget and DIY I can do it the better - plus there's more content and more opportunities for people in the comment section to tell me what a crappy job I'm doing if I build it all. lol If this was going to be a street bike or something like that then I 110% agree just buy a kit. BUT it makes the videos more entertaining when you buy a ching-chong $100 turbo and it shits the turbine wheel out the exhaust pipe mid pull lol Also there wont be any turning it up past just what the stock engine or stock engine + spacer can handle. Not willing to sink that much into it because honestly One thing I'm really worried about with this entire build is how well the hayabusa trans holds up. I think its very likely the trans will let go the first time it sees a whoop section. The trans in the busa wasnt meant to push around a ~1,800-2,000lb 4WD car and the loading and unloading the little gears will see off road.

IDK tho, it could be totally fine because people seem to do WAY more with them than I ever thought.

Next question is what sized injectors are needed? or will stock ones handle it?

Also do you have to run a scavange pump for the oil return or can I make it gravity down into the oil pan? This was my original plan (gravity oil return) but not sure. I'll have to custom make my own intake because of space requirements.

With a FMU and OEM injectors your goals are doable. I swapped to some year I forget which year Honda S2000 injectors that flow a bit more. And made 382 with a FMU.
