depends on use. i wanted the stage 2r 68 as well and was dead set on it . I spoke with mark and went with the 3794a stage 2 from him for a few reasons. it would get me similar results but not quite as much power , slightly quicker spool being a 65mm vs 68mm. lower egt's while towing which is not often for me at all maybe a few times a year. So far i love it , turbo brake is better than stock by far . sound is awesome . Not a huge difference from stock but there is a noticable gain. I have a dsp5 , built trans , goerend converter and fass 150 with down pipe , egr block, and 5 turbo back no cat. These are all prequisites in alot of peoples opinions including my own. My one thing that deterred me from the stage 2r was it will push the limits of the stock lbz , yes others have blown them with just a tune but this turbo mark and i decieded would be best suited for keeping the stock engine alive longer.
I plan on 30-45% over sticks when money permits to lower timing and keep the engine happy. Get a game plan (power level, et or what ever and budget and stick to it ) if you plan to twin it , then plan on building a trans and engine come time. If thats not in your budget then play it as safe as possible.
