Stock shafts will work, pretty much good attention to detail on the build.#1 · Nov 1, 2007. I want to know how much tq/hp a 4L80E is capable of handling... and I don't mean in race trim once a week, I mean in daily-driver street duty. I have a duramax diesel project that (depending on how I tune it) can make anywhere from 250hp/550tq up to 500hp/900tq.Mar 24, 2011 · 6826 posts · Joined 2012. #29 · Nov 25, 2019 (Edited) RocketRobin said: The stock clutch can handle about 360 lbs torque. I swapped mine out for an ACT HD clutch that can handle 522 lbs. Pedal pressure and modulation is ok for city driving, but it's not the nicest. This clutch takes a while to break in. Just wondering how much hp can these stock internals actually handle. The tech guide said you can get a reliable 400hp on the stock internals. Obviously i will be puttin the boost down when i'm daily driven. Also whats a recommended place to get good internals for the 4g63. Thanks! i want high hp but reliable at the same time. Vic.Jul 14, 2009. #2. A stock one will hold up for some time with 500crank hp. Push more than that and it is on borrowed time. Plus with a used one who knows how abused it already is. A rebuild with good & extra clutches will result in 600-700 crank hp. Some more easy mods and you can build them to hold well over 1000hp.Jazzer The Cat. 8048 posts · Joined 2008. #22 · Nov 14, 2008. It is pretty commonly understood that a stock 4.6 in a '99~'04 block is good for about 400HP at the crank. Some have gone higher, but this seems to be a good limit.1.8k. Lexus Model: 1992 SC400 MODIFIED/NOS. Posted May 18, 2006. I am trying to determine how much horsepower a stock 1uz-fe engine can handle... I now know of a sc400 stock motor that dyno'd at 400rwhp without failure... (larger fuel injectors were needed on that motor) Has anyone by any chance pushed their stock sc400 motor past that point ...I destroyed my stock 3.73 non-posi rear end at 4400elevation with a 353 corrected rwhp car. At that elevation it was probably closer to 290 crank hp. The stickiest tires I ever had on it were 275 BFG drag radials.

Your stock turbo will only be in the 35-38 psi range with those sticks. Your usually good till 40+ psi. New bolts should hold it for a good while.
