Nope.

 

Damn I could use them for Racewars this weekend, they'd go for a fortune.

 

How is that different? It looks like a normal manifold to me. What type of improvement do you get from it.

 

Stock 2001 manifold:

 

Ok, I see the diff now. So for the second part of my question, what type of real world gain does it give? Dynos?

 

I thought you were my friend :(

 

There was a fair amount of discussion about this in a thread on this forum about IM design last year sometime. You guys should read every single thread from last year to make sure you are caught up.

 

Sorry, I've lost track with all the PMs coming back and forth (the GB and all). Did I promise to sell you one?

 

No....I've just been really trying to get my hands on one even before the discussion I started :( Maybe you can find me one?

 

If it's less than $200 I'd be interested.

 

Anyone have any theories about square top vs B18?

 

Square top is the way to go n/a for sure. They should both offer similar gains in boost. Squaretop should be a bit cheaper i would think. I had about $500 in my honda mani.

 

Definintely interested, depending on price, of course. I'm cheap.

 

Corksport is selling these for 475.

Would you rather have this than a custom one made or a BEGI?

 

Are these standard equipment in Europe? First I've heard of them as well but if they are then ill start keeping my eyes open in the junkyards around here.

 

Has anyone dyno tested these against a 99/00 manifold with VICS switching?

 

Yep, these are standard on 01+ miata outside of USA.

 

Grab some on the cheap, sell for massive profit.

 

if you find one LMK

BTW I mentioned this somewhere before but does anyone know if it is a different part number. A friend of mine that works for mazda asked me and I dont know. I've been looking around but I can not find out if it is a different part number.
