Im torn on what to Do

I saw this and now im torn on what to do i wanted to get 1.9 rr and a 2.5 downpipe but now i am wondering if id get more gains with a High Velocity Throttle Body for the L36 and a HV3 High velocity intake insert but im not sure of the options id need to get from zzp and keep in mind all i have is a air intake so which decision is best and would they cause more problems down the road?
Thanks,
Bobby

Welcome to AF!!!

I have read the testimonials about that intake insert, and it seems to do alright, but I think it may only help out top end.

Myself I would probably do downipe with the 1.9 ratio rockers. Better check out and make sure that with 1.9's that you dont have to upgrade the valvesprings and timing chain/gears. I thought with 1.8 you didnt and with 1.9 you did.

Chech back again though, Bob and Rich and GTP Dad are very knowledgable when it comes to Modifications, and if you do decided to get that HV intake insert, let us know how things turn out.
