I have been pondering adding nitrous and have been looking at the nitrous express 102 kit and the proton kit. I have a nnbs 217/221 cam, lsxrt, lth, ls7 TB, 4.11 posi. Will the 102 kit work with the ls7 TB? I can get a killer deal on either so I just want what is best for my setup. I don't really want to get into fuel system upgrades yet. I would like a 50 or 75 shot, is that safe with stock fuel system? Also what plugs do you recommend.

 

Id stick with a plate the same size as the tb so it doesn't create any kind of reversion or puddling. Stock fuel pump should be fine for that little of nitrous. Run a fuel pressure safety switch just incase the fuel pressure does get low.. Tr6 plugs should be fine..

 

We have a plate system for the ls7 throttle body, look at part# 20934-10 and 20931-10
