I just bought a 70mm throttle body, I bought this because I am planning on buying an aftermarket intake (not sure on which one yet, probably just a cobra) but it looks like the intake plans are going to have to hold off for a bit longer, should I go ahead and put the throttle body in or would that cause any problems on the stock intake since its the bigger throttle body.

 

I'd wait until you're ready to mod the Pony!

 

Would it cause any problems with just the stock intake manifold? (im asking because knowing me having it and not putting it on the car will drive me crazy)

 

You can put it without problem, just don't expect any performance increase.
