Hey so here's the update,
I have a stock b18a with a 50shot of nitrous in my 91 civic. I purchased a skunk2 intake manifold off a guy for really cheap. It took me a couple hours and finally got the intake out. But stupid me didn't check if it would line up perfectly. I guess its a lesson I just learned the hard way. Anyways turns out its for the b18c, he took it back no worries and refunded my money.
Now the question is which intake manifold should I get. Skunk2 or Blox? Or does anyone know of a better one thats in the price range. Since the stock ones out, might as well upgrade.

 

I ran the S2 on a boosted setup for a while but it was choking my setup so I switched to an edelbrock.The edelbrock units are better performing but they tend to run a bit more money.Aebs also makes or made an intake manifold.I would choose AEBS or S2 before Blox though.

 

thanks for the reply. I have been reading up on it and it sounds like an upgraded intake manifold on a non vtec motor is not worth the money if your engine is stock. It seems like the way to go is to clean and port the stock manifold. What are your thoughts?
Cheers!

 

i had the bloxs with a 100 four fogger direct shot on a b20 and had no problems and the bloxs is a little cheaper then the skunk2

 

Well there you go you have first hand experience.I would try some of the nitrous guys in the nitrous thread for help.I could chime in a bit if the car was boosted but I have very limited experience running N2O

 

How much hp were you running? Just wondering why it was choking your engine?

 

I have the Skunk2 intake manifold. Love it.
