I got a type R manifold on my car- couldnt notice any gains..i think about 4whp is what ive heard. Its good for me now cause i got turbo. Id get it if you can get a good price, It will only help you later on when you mod your motor.
people lie or exageratte power gains all the time, local shops will say anything to sell a product... i've heard lots of people say tons of wheel horsepower, but on dyno runs most intake manifolds did next to nothing especially considering the price, other than turbo cars of course or very highly modified n/a
You didn't specify intake or exhaust manifold. My 2 cents, spend the dough on the exhaust manifold. That's more restrictive to your system now than your intake manifold. The manifold will lose power if you're no backing it with more than just a CAI and exhaust.
I have a Skunk2 manifold with my setup because I'm running a chipped P-28 on a B18C1. Anyways the manifold helped me, I gained 10-12Hp / 10Tq untuned at 5.5psi. I think it's worth the $270 I paid for it.
I´m running the manifold as well and it works great, you can feel the gain up top...people say you need to have it heavily moded but I put it in only when I had I/H/E and couldnt complain about it then..now I have skunk2 cams, gears and skunk2 chipped ECU and it ROCKS!!!!!
I have the Skunk2 Manifold also, I like it and yeh to have any real gains, you need alot of mods, but its worth it for me heres a list of my mods.
