i have a ls/vtec with b16 tranny jdm hydro and b16 head with gsr cams and gears etc. but i just want to know because im going boost and should i keep the Si 99-00 intake manifold or get an aftermarket one, and ifi should get an aftermarket which one is good for holding 12-18 psi and probably 300 -450 hp or whp?and does it make a differ to get an aftermarket or no and do many ppl do it? i just want to make this thng safe because boosting is already not that safe lol

would it fit onto my si head i think it will but want to make sure? and you know anyone who has one for sale at a good price?

A GSR manifold does not have the same bolt pattern for a B16 head.

Sick with the stock IM for now. Solve all your turbo install problems, then upgrade later if you want- Skunk 2 or JG
