I have a 90 K1500 350 5spd Getrag. I am wanting, and kinda needing a K2500. Now I know that i can go out and buy one, but where is the fun in that??? Plus, I can spend around $10,000 now for what I need, or, I can spend the same amount over a couple years time frame, and have even more fun by doing the work myself. Powertrain: To start with I am looking at a complete powertrain upgrade. I talked with the techs at summitracing.com, and found out that I can get about 350-450 HP and 500-550 lb-ft. torque for around $5K. I know I am gonna have to change the tranny because I have found that anything over 250 HP with damage the input shaft on the getrags. I am contemplating a NVG4500 or even a NVG5550 with the PTO to handle the power. I have a New Process 241 Transfer case, but am looking at getting a 205, or a T-10 rock crawler to get more reliability with the higher power. Suspension: I want to do a K2500 Full Suspension package. I know the C-Channel Frame Rails are the same from 1500 to 2500. But I think that I am gonna have swap the front A-Arms, hubs, Torsion Bars and probably the T-Bar Crossmember I am wanting to get these from a 2004 to 2007 model if I can Simple because they have a higher load capacity. In the rear I am Wanting to actually go with a newer system period. Definitely from a 04-07 truck because of higher weight capacity and better stability control. I want the whole axle too so that I can get a "cheap" Disc brake upgrade. I also like the sway bar on the axle. I think the newer axles are wider than the 90's style, So I think there might be some trimming required. These are just ponderings that I have over the last couple of months and thought that I might ask some people that could've possibly attempted and succeded (or failed) and possibly what I am looking at. Thanks for reading.
