I just recently purchased a weber 45 dcoe carb (off ebay) with the lower intake manifold for my 83 rx-7. Was wondering if i'll need new linkage for it, and if I'll need a bigger fuel pump. If so what fuel pump do you guys reccomend? Not too worried about the linkage if I do need it

 

Your gonna need a new bracket to hold the throttle cable housing. I made my own. You will need a new fuel pump, I use a Holley Red, with a Fuel pressure regulator.

 

thanks alot, now i gotta order a fuel pump and regulator hah

 

Here's the thread I made with my set up in it. Pics so you can get an idea.
