i have found a good websight where they sell them in any configuration i want,. but the main thing is, would it be possible? i mean allot of fab work would be needed, but is it really possible since i need to plumb a shitload of stuff into it. cus i want to replace the whole uim, cus i hate taking it off to get to the lower injectors. its a killer job. plus i think it could possibly make a shitload of power. but i think i would have to hack the air sensor. what do you guys think?

Not a good mod for a street car. You will virtually eliminate low end torque.

what's 'itb' ?

I have a possible meaning for it but I don't think it's the right one

by itb's i assume you mean induvidual throttle bodies. Like the ones that i see on ebay with the blue horns and dual incectors on each T/B... you have to use a webber type LIM with those though.. bye bye six ports if you got em..

If you have a TII and were planning on going with a Stand Alone ECU anyway... then go for it.

But if you have an N/A I don't think you are going to see enough power gains to make it worth your while. And I REALLY don't think its going to be possible without a Haltech, Microtech our Autec..

That's a bit of an exaggeration. I know numerous people happily running either IDA-style EFI or a Weber IDA carb on street cars. Any NA mod that enhances top-end is going to lose you a bit down low, but they're far from being unstreetable.

Not if you use a sidedraught UIM that bolts to the stock LIM.

I was being dramatic. For the effort required to install those suckers, on a stock port engine, I don't think it's worth it...

NZConvertible

Definitely not on a stock engine. We don't have NA FC's over here, so most of the time these set-ups are replacing a carb on a 4-port engine. That makes the improvement a bit more dramatic. I've never seen any back-to-back tests between the stock FC NA manifold and an ITB set-up, but I think you'd need to be aiming fairly high to warrant it. I think a big street-port would a be a minimum before the gains are worth the time and money. On a mildly ported engine those ports are still the restriction, not the manifold or AFM.

so it wouldnt be worth it?

damn. cus the main thiung i wanna do is make a completely now im that gives easy access to all the injectors.

NZConvertible

You want to install a whole new intake system and a whole new EFI system just for easy access to the injectors?! (I think that's what you're saying. You should proof-read your posts...) Seriously, how often do you need to do that?

Unless you are specifically planning a high-power NA motor, no they are not worth it.

i just think it would be better withought all the damn turns the air has to make, just to get to the engine.

NZConvertible

Those turns are there to allow long intake runners to fit, which improves torque and fattens the powerband. Short runners (i.e. IDA's) make more peak power at the expense of bottom end. For stock and mildly modified engines, the engine's ports are the main restriction, not the intake manifold.

How modified is your car and how much further do you plan to go?
