throttle body, sizes and stuff Options

[thedro]

yeah im thinkin on port and polishin my intake manifold but my cousin told me i should just make (custom out) a new one for it cus its so freakin small.. but if i want a bigger i-manifold then i need a bigger t-body.. so im not sure but i heard the 5sfe's t-body is 2", so thats one question how big is the stock t-body for the 5sfe.

next is how much bigger do u think i should get the next one.. supra's (usually upgrade, if theyr not goin for extremes) to the q45 t-body which is 3" but i think that might get a lil too excesive for a 5sfe, i think i should get a 2" 1/2 or somthin around ther, so im also wonderin how big is the supra's stock t-body.
-thanks

well i dont think anyone has yet to do this. as far as i know larger intake manifolds dont exist unless you swap for one. But i have no idea what you could swap inplace.

On the flip side, where are you going with this. Think into the future and decide whether there is a point to having this done. Supras if your talking about the 2jz have larger Intake manifold and throttlebodies because they are expecting to push 500+ horsepower on a turbo motor. Your GT probably has no need for a 2.5in intake manifold and larger throttle body.

The guys that are turboing their 5s havent had larger intake manifolds added, so as a backup source, why do you need one.

If your looking for a boost in power, your only option is FI. Either turbo or supercharge the 5s. I wouldnt bother doing the NA upgrades.
