trying to find out what it takes to put on mikuni sidedrafts on my 86 rx7? if anybody has any info let me know please. buying setup from somebody that said i was on an 87 rx7 has half the intake manifold attached already. my rx7 is stock with 13b fuel injection

 

I'm not sure if this is the same bolt pattern (it says it's for dellorto), but racing beat sells:



Upper Manifold Section for

86-92 13B 6-Port



Part Number: 18101

Retail Price: $150.00

 

How did the manifold/ Mikuni work? or did you find a different intake option? Do you have a contact for tune suggestions? I'm running the same setup on my '83 race car. 13b 6pt w/ mikuni. Carb was tuned for a 12a. Any help would be greatly appreciated !
