Spraying 200-250 ... what do I need to do? I'm looking on spraying 200 to 250 on a rebuilt ls1. While I'm in it, I was planning on doing forged pistons (weiseco forged pistons from MTI). What else should I do? Also, what is the highest compression piston I can run on pump gas?

Forged pistons will be a plus. If you can, since you will be in the engine anyway you might as well go ahead and get forged rods too (I prefer a quality H-Beam). As for compression, a nitrous motor doesn't react to compression the same way a forced induction motor does. So you really don't have to worry about running too high of a c/r as far as the nitrous is concerned. However, for pump gas I wouldn't recommend going any higher than 11:1. I personally like 10.5-10.8:1.

I run forged je flat tops with a 68cc head and it works out real nice.If your going to start hitting the motor with a 200-250 shot your going to need some octane.Unless your willing to take the chance of dentation.When i ran a 200 shot i ran 104 unleaded fuel that worked nice for that size shot.When i started hitting the motor with more nitrous i went to leaded fuel.I just tuned open loop and it was the best thing ever did.
