Hey guys, I have a Jun intake manifold on my rb26 and have a 90mm throttle body. The damn thing sticks around the closed position so sometimes it doesnt close all the way which messes up everything. What are you guys running? I saw the Wilson TB raw brokerage has, it would be nice to run a GM or a Ford tps, as i am on my 3rd Nissan one in under a month... POS...
AEM EMS series 2 ecu.

Sure its not your ECU's fault for that one? Factory TPS never gave me issues on my Haltech... granted all your set screws are tight.

wow, iphone auto correct sux.... I have that throttle cable but it doesnt look like that will work on the wilson throttle body. I emailed Wilson to see what cable end they recommend. I will proably end up using a clevis on style on the petal end and do away with this bullcrap oem style Z linkage...
