how big is the hole in the factory renix manifold ,does the head need to be reworked to take ful advantage of the bigger bore , just because you putting more fuel into the motor does not mean the motoor can burn it to create more horse power

Technically Hes putting more air down it, not fuel. And the throat of the intake manifold is actually bigger than the throttle body on the renix
thats all that aftermarket TB does: opens it up to a straight through dump (basically)

Thats a fine setup, but a little on the lean side, I would run neon injectors,
with all that air flow your gonna gain.

And you can find injectors cheaper than that site btw
