Nitrous kit on SSR
Burt: concerning nitrous. I purchased a "Cold Fusion" wet nitrous kit. It is specifically made for the LS generation III engines. The kit was fairly easy to install but to make it look right it can be labor intensive (removing the saddle bags to fit the bottle inside of the bag...removing the bedliner to lay the nitrous feed line...etc). The directions are somewhat confusing when it comes to the actual wiring of the micro switch. Part of the reason is that our SSRs have a throttle body that is actuated by wire so the micro switch must go on the floor throttle pedal. That was really the hardest part. I wired the fuel and nitrous solenoids straight to the fuse box (driver side engine compartment) You can get a 12 volt source coming into the fuse box from the battery. The fuel rail has a shrader valve that you can remove and use for the fuel solenoid "extra gas". I wired a bottle opening actuation switch and a nitrous arming switch right into one of the accessory holes (either side of the ash tray). Everything looks great. I'm starting off on the low end with a 100HP shot. My next project is LS-6 ported heads to go with it. Love the truck but have the need for horsepower.

Scott, you are correct. However the kit I have is capable of making 250 but not without some internal mods and more fuel. From what I read the absolute worst thing you can do to a nitrous engine is to be to lean on fuel. Up to about 100 HP shot you are probably safe on stock fuel flow. The SSR fuel system can handle additional fuel (via a fuel solenoid linked with the nitrous) so that part is a given. I went with this particular wet kit for three reasons. 1) It is specifically made for the LS engines (basically what the SSR has except for piston bore and valve size on the heads) 2) It lends itself to an upgrade if I ever choose to go that route 3) and maybe most important the price was right. I remember my younger days when nitrous was a scarey thought. The new systems are quite good. Considering the amount of time you place the car at full throttle and over 3000rpm it takes a long time to use a 10lb bottle of nitrous using a 100HP shot. Cars that have Turbo's or Superchargers gain an incredible amount of HP when coupled with nitrous due to the cooling effects of nitrous. I'm currently porting and polishing a set of LS-6 heads with the larger valves. I plan on putting the heads on at the same time I put a Magnusson Supercharger kit on. I'll detune the nitrous to 50 HP until I can gather the info as to the stress I'll be placing on the drive train. I believe the trans will be the weak link. V/R, Lee
