Default Kc S300 63/68 or 63/73

Running a 2002 F250 as a dedicated tow rig, just exploded the billet wheel in my 38r. Was never really completely satisfied with that Turbo, although it was a significant upgrade over stock. So what are yawls opinionWhy or why wouldn't you get the bigger or smaller turbine wheel. Truck has stock injectors, 4" downpipe, bellowed up pipes, and ******d pedestal. Also running DP tunes

FWIW, with stock injectors I would run the smaller turbine housing for quick spool up.

Yeah that is my plan, That is also what KC recommended, They also recommended the 68 whee, especially for a tow rig. The largest injector I would ever put on this truck would be the smalle hybrid, 205/30s and that's just because it's easier on the oil system I can detune to whatever's needed

Well the 205/30s change everything. You need to decide if you are staying stock or going with 205/30. Stock and 160/0s would be great on the 68 turbine wheel, but you would want the 73 with anything bigger I would think.

Yes I'd agree to an extent, except the truck will 90% of the time be towing. If injectors need replacing, im not going back with stock. And I've had 180/100s on another truck, and I loved them but they were oil hungry. That truck was 96, BASB turbo, and all the other crazy fun supporting mods lol. That truck towed like a freight train. So the reason for the small hybrids isn't for the max power, but to deliver fuel without taxing the oil system, and still make good reliable power. I would even consider an 80% nozzle, but not sure its recommended on smaller hybrids. I originally started with 160/0s on that previous truck, and to tow at the power levels I liked, couldn't ever keep egts in check, going bigger made all the world of difference.

Sounds like what you really need then is a T4 setup with the 364.5/.91 with the small turbine and 205/30s. That should do exactly what your asking and do it much better than a drop in will.

I have 180/30s so not exactly apples to apples but with the 364.5 with the larger wheel and .91 housing in the tow tune does great with only smoke happening from flat footing it from a dead stop. If your staying stock Id do the smaller housing. If you go bigger than stock nozzle Id go bigger housing.
