i have a 90 integra and its a 92 motor and tranny. 5 speed. motor is stock. i have a cai,2 1/2 header,a coustom 2 1/4 cat-back with n1 muffler and a zex dry nitrous kit (35 shot). My question was that I whanted to know if i should make my own itb out of a hayabusa throttle bodies? would it be better porformance, hp,torqe,or sound wise? i know its going to have a better throttle response.would it be worth spending 300 bux on making this?
also my plans are to make a ls/vtec, and then build the bottom for nitrous, like pistons, rods ect. or might stick to all motor. i konw if i do this im going to have to do a direct port for nitrous. also im trying to get to the 11s or less so what would be better a all motor or a nitrous motor? i dont whant turbo cuz of several reasons. sorry for so many questions.

 

$300? More like $1500.

 

no im makingone of my own off of a hayabusa throttle bodies. or i can buy a used toda one for 1000 bux.

 

You'll never make a set of ITBs from components for less than a grand, and you'll hit $1500 before you're finished installing them.

Toda has never made a kit for nonvtec engines. You'd have to swap your head first, then install the Toda kit. Which will, I guarantee you, require more than just the $1000 kit.


Plan on $1500 to get some ITBs complete and under your hood. Then you need to think about engine management, which will run you another thousand dollars. Then tuning.

all you need is your mani and cut out what you need.

 

And then you need airhorns. And then you need injectors. Then you need a decent filtering system so you don't trash your engine... which will require you to modify your fuel system if you want it to pick up air from the standard intake location.

You're dreaming.


I won't even start on how awesome that must flow, with the hacksawed runners pressed to the flange of the ITBs with some hose clamps.

 

Yep your looking at $1000+ here man! Goodluck. People do get deals though.

 

Why go through ALL the makeshift parts just get the PROVEN TWM Induction ITB KIT for $1599.00

 

Again, that's not the complete package unless you want to run unfiltered.


I have the TWM kit with airbox.

 

ITBs aren't even worth it on a mild n/a setup.
