I have a Webber intake set(no carbs) I want to dual T/B set up for my L30 Diesel build. What size are the factory intake holes, and know of any T/B's that will bolt up? I am aware that Diesel's are controled though fuel, not T/B but i can jam them open. I just want some kind of way to filter the intake air

 

sounds like you'd be better off having some simple manifolds made up to save the risk leak involved in the butterfly shafts if you don't need to regulate air. steel pipe, flange on each end. couldn't cost more than $30 each i expect.

 

I might go with two gutted Webers. Hell it's guna have a header on it. a P90 head. Keep it lookin Gas powerd till you start it of course.


Edit: You know. I completely forgot about the LT1 T/B i got right before i left. Hummm Ideas.

 

there is a kit that takes dual su carbs and converts them to efi as well. if you take a dual su manifold and install stock zx tb''s on them that works as well. you have to add injector bungs (not needed for you of course) and re-drill the carb flange. both setups covered at hybridz. i also read somewhere that you can change the guts of some webers to make them efi too. personally id go with the dual su mani,fold and put zx factoy tb's on it, that way you can use the su's throttle linkage.
