I have posted a similar question in the Forced Induction section, and now that I have some answers, and suggestions to post it here, well, here goes.

I have a fairly well built 355 TPI with hyer pistons and a forged crank, resized police rods, Crower cam with an Advertised Int. duration 278/497 lift Exh. duration 286/518 lift. Roller rockers with matched 6500rpm springs and HD pushrods. Everything has been ported and polished and has a jacobs Ign. coil and taylor 8.8mm wires with AC t45? plugs at .35gap with Bosch 22lb injectors and an adj. fuel reg. at 50psi. The heads are iron with a 62cc and 10.6CR.

With the engine, is it built enough to handle the stress of nitrous of say 125-150 shot or would it not handle the nitrous?? I 've been told it'll handle that amount easily with the right tune and could go as high as a 200 shot. Is that person insane on the 200 jets?

Also, before I would strap the bottle in, I would do any and all safety precautions first. RPM window switch, full throttle switch, a bigger inline 255lph pump and prob get bigger SVO injectors (30-33lb) and get the dry kit for the TPI behind the TB. I will also invest in an EGT guage and setup plus the A/F ratio guage to keep a keen eye on whats happening. With all of this and the the jetting, should I go to a bigger size fuel line than the factory size?

I'm not sure what kit to buy but a few have said the ZEX kit would be better because its a "safer" kit and easiest to install, coming with ALL parts and more user friendly.

All aside, for the TPI TB kit, what do u think is better and more benefitial, wet or dry???
