two different cars.

one is a 99 the other a 97 with a 99 head and MSM intake cam.

both running 14psi, the 97 (blue line) dropped to 12psi; id expect the 97 to hit 300hp if it held that 2psi.


i was just showing the results are easily repeatable.

Yeah I always wondered that too. Slightly different exhaust manifolds. Pauls was symmetric, Eds was not.

And Ed mentioned the head had some work done to it, maybe a different cam, i forget.

EDIT: AHH I didn't see Scotts post, he explains it.

IIRC it was a worked head too, like larger intake valves, maybe ported. i dont quite remember.

Just read all 30 pages of this thread.

I'd really like to see someone use the stock GSR manifold. If you took advantage of the IAB system inherent in that manifold, then all of this talk about short runners versus long runners is then a moot point. You'd have BOTH!

Yes, I thought about the GSR manifold too. I picked one up on Kijiji, and it turns out this manifold is too wide. You would need to hack the runners down significantly. The manifold is very heavy too. IIRC the throttle body would end up too low as well. So basically, it won't fit easily.....

I recently removed my stock throttle body and installed a cheap 70mm blox unit. I then added a 94-97 IAC right on the manifold. Not real pretty, but it works...

Too wide in that it won't fit between the head and the strut tower? Or too wide in relation to the taper of the runners to port spacing?

Probably the latter, look at the spacing VS what is shown in his other image. How's the power curve look on that oreo? You should put your setup in your sig.

The GSR manifold has the exact same port spacing as found on the other B series, The flange is just a bit different.

Back when I still had a miata, I was planning on putting a regular old LS (b18b) manifold join my car. Its not as blood as an ITR, but its probably a lot better than what we have, and the runners are long, so it would most likely not give up as much in the midrange.

LS manifold and ITR manifold (The Skunk2/Blox manifold is modeled after the ITR):


LS flange, ITR/B16 flange, GSR flange from top to bottom:

If you cut the runners, so that the manifold does not hit the strut tower, then the port spacing will be off quite a bit. Also, since the throttle body inlet is under the manifold, if you have the runners parallel to the intake ports, the manifold will hit the frame rail.

Maybe not the best picture...

Has anybody who's done this actually used the Performer X intake as a basis? All I see is Blox and Skunk. Wondering if the Performer might actually be longer, and maybe "plenum hit shock" or something. I see the angled throttle body flange, as if it's trying to point the T/B into the same place as all the other manis that have straight flanges.

I pretty much maxed out the room available on my skunk manifold. I had to pull the MMR motor mounts out and put in a pair of mazdacomps with the stock steel cups to raise the engine back up that 1/4" so the manifold would clear the shock tower. I also had to cut some of the diagonal bracing that runs between the shock tower and framerail for the plenum to fit.

I think anything longer and you'd have to engineer some angle or rise into the flange or into the seam between the two chopped runners, depending on which fabrication method you take. The only direction to go is to raise the plenum vertically.

Excellent, seems cheap enough to try it. Especially since I have an extra manifold sitting around I can hack up. Thank you sir.

Finally decided to take another 10 pounds out of the nose of the car I see.

Not sure what the total weight change will end up being.
