I will be running diamond pistons and jbp rods. What is the most nitrous I can run? I would probably do the port type system to prevent fuel drop out.

Thanks,Chris.

 

I think the sleeves are rated around 700 or so and the crank more. But a 300 shot should be out of the question.

 

I think Gm says a 150 shot. unless you go progressive direct port than you can probably get away with a 200+ shot on there. just the hit of a big shot all at once is what will break the crank

 

Excelent hehehe 200 shot progressive it is some day.

 

im almost possitive ur correct.. i just dont have my gm build book around me.... im planning on running a 75 shot in my 2.2l nd that will be plenty safe on stock internals... considering that the gm build books states 50 shot with 8-10 lbs of boost... on stock inards

but a wet shot is the only way to go!!!! dry is just asking for the big boom

 

I think a 125 shot should be plenty for you considering clutch and traction issues...

that on top of whatever size pulley you have (atleast 3") and you should be riding in a 12 sec. Cobalt...
