Truck: early 99 with zf6.
Goal: reliable beater tow pig. No drag racing or sled pulling! No 4000rpm clutch dumps! I want the truck to like to work.
Current state: stock except for SMF w/ stock replacement clutch, 4" exhaust, and big air filter.
Plan: new clutch, new injectors, modified turbo
Injectors: Rosewood 160/0 or 200/80. I like the idea of a nozzle that isn't extrude honed to size, but can be swayed otherwise. Stock 15° HPOP is healthy, so small single shots or hybrids are appealing. I figure that one of Rosewood's favored tuners can make them behave.
Turbo: Rebuild with 360° thrust, new fancy compressor wheel, and new KC 70mm turbine wheel (which I have in hand). I also have a non-WG 1.0 A/R turbine housing, but for a 68mm turbine wheel. Plan is to have the 1.0 housing machined for the bigger turbine wheel. For the compressor wheel, the BD-type non-stepped wheel is appealing, because the factory wheel is LOUD, and I seem to gather that the WW2 and the 4/4 riffraff wheels are noisy too. The factory WW is way too shrill.
Clutch: I don't know where to go here. I want single disc so my syncros don't get hashed. Most clutch discussions on this site seem to focus on 3200-4000 rpm loaded launches pulling sleds or drag racing. I'll be doing nothing of the sort; instead I want to get a big load moving off-idle in low gear without shaking the truck apart, and have the clutch hold the tow and daily tunes. If it can hold more, great!
Other mods: riffraff fuel crossover and some sort of HP oil crossover. Gauges for EGT, boost, and maybe fuel and HPO pressures.
You guys that have been down this road before...any comments or recommendations?
Thanks
