What's needs to be done to run a aftermarket tb? Can you just weld a flange where the stock tb flange use to be or is there something a lil more complex that needs to be done?!

Physically mounting a different TB would be the first step, adapting the TPS would be the second.

 

For most applications there is basically no point in an aftermarket throttlebody, and a single blade design hurts part throttle response. If you have a stock or bolt on turbo forget it. You're wasting your time.

Is this what your interested in?

 

agreed. that's one of the LAST places for horsepower to hide on these engines.

 

I have a FD upper with the Rotary-Works 90 mm TB on it.
the Difference between the Stock FD TB and the R-W TB is Night and Day.
I had a hesitation on the FD TB and when I switched over,the Acceleration is smooth as Glass.
I'm not saying there is more power,I am saying that the Engine 'likes it better"!..and so do I!

 

FD throttle body is the best option for stock ECU/manifold...

 

Is it a direct bolt on? Tps?

 

no its not a direct bolt on, and you have to wire the TPS in. It's not complicated at all though.

Little bit of work, and its a great cheap upgrade though.
