I have a prototype header made for 86-91 RX-7's



It was made to out perform RB/Pacesetter and bolt up to the stock main catalytic converter location, so no 220$ pre-silencer required.



But what I'm looking for is a market for a N/A Header, if there is I am willing to offer a quality piece.



I cannot make all of these so I will have to locate a manufacturer to produce these, I will work with them to insure material & weld quality.



I will need a test car to perform a dyno test, hopefully they will have a RB combo that can be dyno'd against but that is hard to find in CA.



Just throwing this out to see if there is still a performance interest with in Gen 2 N/A Rx-7's.

Nobody? https://www.nopistons.com/forums/pub...1047683561.gif

fc'ers especially n/a guys will wait to see a price. and it will have to be better then the SBJ header.



if it is comparable to the SBJ header there are a few guys on the other forum willing to pay decent money for it.



kevin.

It will perform upto par with SDJ, I'm not saying its "better" cause I have no dyno's yet but will be a great header for street use & fitment



as for power gain's this will perform with the SDJ.



Dyno coming in 2-3 week's, I am sending the prototype off to a forum member in NM, there will be back to back run's against corksport & maybe racing beat header's.



This is a third party dyno test and I am not involved in it, cept for sending my header to the tester.



As for price I am trying to keep this at a very reasonable level.

I has am R+B so it'd be nice to see some dyno tests. Interesting to see what the others would do as well!

This will be the version for street cars, I already have a slight ajustment to make on the front primary thats good for a few hp. I do not have time to do so before the dyno.



I already have another one on the drawing board to dominate all others, it is in the works. I am hoping that it wil benefit stock/street port's also as much as highly ported engines. who said N/A RX-7's are lame? https://www.nopistons.com/forums/pub...#>/biggrin.gif

WOOT FOR N/A 2nd GENS!! lol would love to see the dyno results keep us posted

Yeah, I'd like to see some dyno results.

If it is quality, in both performance and craftsmanship, I would love to get my hands on such a header. Also, a reasonable level of noise with a high flow cat would be a good feature.
