Rb25/30 Engine Revs With Slightest Application

[walky01]

hey i have ALMOST finished my rb30de engine, im using the rb30 accelerator cable which ill need to modify, anyway the car doesnt seem to like running on the twin throttle body setup atm. i dont know what the problem is with it however as soon as you tap the accelerator it just revs untill i kill the power. seems like its sticking somewhere or theres too much air going in, the spring on the tb/s arent there or the pipe that goes from the plenum to AFM pipe. need a solution if anyone has an idea.

what happens if you open the throttle bodies a little bit by hand? does it still just rev up, or do the revs just blip like they should?

Because its fine by hand it will more than likely just need the return spring fitted to both throttle linkages.

Cool setup though what comp ratio did u build it too?

hey, i spoke to the guy which i purchased the motor off (this forum) it hasnt run the spring at all so over the weekend ill muck around with it a bit more as the acc cable is way too long, off an rb30 so i need to shorten it and also get a tighter spring whichthe accelerator cable goes off. then ill see how i go. hopefully all is well. fingers crossed.
