Will the P73 Type R Intake work without errors on a P75 head or do i need to change the sensors on the intake itself? Does the B16b intake breath better than the b18c5?

a vtec b-series intake manifold will not bolt up to a non-vtec b-series head

you can make it work, you need to modify the coolant inlet and the bolt pattern on that side the head.

First of all the P73 Type R manifold is the same manifold on both CTR and ITR motors

Second, as mention, vtec manifolds don't fit non vtec heads, why would you even bother? The P73 isn't that great. I've seen the B16 P30 manifold make more power on a lot more engines.

It you want a better manifold for an LS head, i would say you have 3 good options:

- edelbrock
- skunk II
- have your stock manifold ported- extrude hone is awesome!!

Sounds good. Reading up on the Edelbrock Victor X and its only plus, no downsides at all. Looks like a good buy.

haha, the victor on a stock ls? i forsee bad from that. that intake manifold is far to big. i would at least go with the performerx
