i have a jrsc on my lsvtec with about 10psi, i just bought a spearco waterinjection kit. was it even worth it or did i just waste my money. i havn't put it on yet. i bought it from a guy for 100 still new.

 

sounds like a good deal to me... those intake temps get close to 200 degrees out of the JRSC... you can easily add a couple more psi if you get those intake temps down... especially w/ a built motor... cant go wrong with anything for 100 bucks

 

you wont see a HP gain but it will be safer for the engine!!
