My bro is looking to purchase two things for his k swap. He wants an aftermarket fuel rail and an intake manifold. Any suggestions on which route to go?

 

Your thread title is RBC manifold. Are you asking about that manifold or specifically a non-OEM IM? RBC is just about as good as it gets for a street car, what's wrong with that? What car, and what motor exactly?

I see you're from Seattle, good to have a few more PNW members around here

 

yeah rbc is good for a street car n good for the price!

 

I guess I forgot to mention that the manilfold he was thinking of doing was the Rbc, that's why I put that. He wants something that has a little of everything. Mainly street use but it will be seeing some boost. I know a lot of people retain the stock manifold at times but he wants a bit of the "wow" effect. Yes, we're in Seattle, don't go on here much.

 

i would go for the rrc i think it puts out 4 or 5 more horsepower than the rbc

 

i do not believe the RRC makes that much of a difference....i listed a link below that compares them, there may also need to other modifications to make it work depending on the k-swap of OP's brother, what car is he putting the swap in?? i ask because as the RBC is the best i know of for DC5 drivers and k20-swapped EP3's there are much better k-series intake manifolds out there...IPS, AFI and Blue Print, etc...all make them...

here is the link, good info in this thread: WTF, why the hell is 8th civic blocked....anyway go to 8th civic and look up RRC vs. RBC comparison

 

Another thing to remember when you get a manifold swap is make sure that the car is tuned for it. If you were to just bolt on an RBC, or any other IM for that matter, you would more than likely lose power...

tuning is everything!!

 

You're a mod, you should know

IB is watching us

 

Im waiting for a response from the higher up mods. We will see lol

 

he only said K-swap


manifold depends on what K series. If k24 I highly don't recommend the RBC. If k20 than sure RBC is your best bang for the buck.

 

True ^ I was assuming K20...

 

Why not for a K24? j/c (assuming K24A2 right?)

 

I think the skunk fuel rail looks nice.

 

theres a mag that has a write up for k series manifolds comparison it jst came out or it was last month..

 

The RBC is great for high reving engines like the k20. I lost almost 30ft lbs of mid range torque and only gained 3hp at the last 500rpms swapping to the RBC from the stock k24 manifold. The loss of low-end and mid-range power is not worth a hp or 3 gain in the high RPM range.

Even Hondata has an article about it saying how they were disappointed in the results on their k24 with the RBC and swapped back to stock manifold.
