This is a Miata part if you're willing to cut it and get someone to weld it to a cut Miata IM flange/runners as discussed in this thread:

https://www.miataturbo.net/forum/t43103/

This is the Blox Skunk2 replica, and has a larger plenum shaped for more equal distributions. Flows to 8200rpm on Honda B16/B18 thingies.

I'll never get around to finishing this project out, and want to buy my daughter a kayak to take her out on the lake with. Tired of being in garage with a car that constantly gives me crap and always fails me, so I'm leaving it as-is and just keeping it running.

Manifold is in the top of this picture, compared to a B6 mani:



And on the right, same comparison:



Looking into plenum you can see the better entry into the runners



$125 plus shipping OBO

I also have a 60mm B18 throttle body that mates up to it that I can include for another $25, and a B6 manifold if you have a 1.6L and want to minimize downtime. For the mani I'd just ask $20 and that you cover the extra shipping weight.

This has potential for those of you who want to make more than 230ft-lbs of torque and are seeing torque drop off at high rpms.

Thanks,

Damon

 

Hmmmmm

 

You know you want it.

It's supposed to be much easier to mate to the 1.8L flange since your injectors are in the head, and the runners line up almost perfectly at the two flanges.

 

I'll take the throttle body, Pm me your info.

I was wrong on the throttle body...it's ~60mm, not 68mm. I just remembered it was 8mm bigger than 1.6L OEM piece, which is ~52mm.

It's yours if you still want it, sending PM.

 

Bump....some interest, no one's committed.

 

Looks like this project may seen be seen on Sav's track monster.

I'm expecting sponsor status, and will use it to put this on the side of his car:

 

bump

 

still waiting on deals to firm up, no one's committed

 

Is this for the B18C5 (ITR/B16) or B18C1 (GSR)? Just double checking. Need one for GSR.

 

The throttle body?

Pretty sure it's from a GSR.

The manifold came off a B18.

 

The IM. Both the GSR and ITR are B18, however, they are not interchangable.

 

Hm...really now.

All I know is the head it was attached to was an LS...and it was in one of the boxy civic hatches. Somebody's wicked n/a drag car they were revamping.
