Should I get the Racing Beat holley intake kit?
Hello guys, I'm back again. I'm looking for some advise on my 79 rx7. Now my rx7 is all original but I'm considering changes a few things with it. It definitely needs a complete new exhaust system, I'm planning on going with a Racing Beat setup. I've also been considering going all in and getting the a racing beat holley intake kit as well. I'm kinda leaning against it because my engine is all original. Does it make sense to get the holley intake kit with the Racing Beat exhaust system?

No, it makes more sense to either modify the nikki or get the RB Weber IDA setup. The holley setup pretty much sucks and will not perform well on corners and doesn't do well on rotaries in general.

Hi JEFF20B....
is there a knowledgable member that is willing to do the 'hogging out' on MY NIKKI & change the jets... (basically) Someone to do all the modifications to get max potential out of the thing... for a charge, of course.
I am leaning towards a WEBER 48 side draft.......(my good friend has a 12a WEBER type manifold he will give to me)... I'd rather have this, Weber set-up, just cause I think it looks cool..however, if I can get more power with a modified NIKKI.. I'll go that route... all kinda around the same money..
Thx

You can possibly mod your own intake manifold for more flow but only if you know what you are doing. You do not want to get rid of the stock anti-reversion lip where it joins at the engine. The port sizes are going from small to big for a reason. It reduces the reversion pulse that rotaries have. The bigger the ports, the bigger the pulse. That is why I recommend 74 spec ports as the perfect street port.
What you are wanting to do with the manifold is remove the shudder valve and cut a new channel like the other side, and do other clean ups and emissions block offs. All 81-85 manifolds have this same layout. Don't bother searching for a 79-80 as those have worse secondary runners. The nice part about the 81-85 manifolds are the better secondary runners and the primary runners that can be cleaned up a bit for max flow and can outflow a stock 79-80.

The 48 weber side draft will work fine. If the intake is the shorty side mount, the only issue is getting an air filter to fit and adding a heat shield to keep the header heat away. If its a wrap around like the one from Atkins or RB, its will be more streetable cause it will have better torque down low but will also not rev out as high as a modded nikki or the weber on the shorty manifold.
