Custom Inlet Manifold?

in all honesty though would it be better than an inlet mani from dave with a big throlttle body on??

It all depends on set up and what you want to achieve. I would say one of daves for drag where top end power is needed but itbs for response on a track car with a mid sized turbo like a td04 but that's just my opinion

Thanks for all the input guys, all have been repped :D

Would be interested to see if the gtir inlet could be made to work Alan? :)

So it would be a good good idea, but maybe with some different ITBs?
Guess to get a plenum made around them would cost too?
Also would be ok to run the setup with an EMU?

The only other options i have are the 5e acis manifolds, which work well with the EMU apparently, wish some more info could be found on it?

And obviously Dave Bs custom inlets are the other option but am not made of money and cant keep spending like i have been doing lol

And going to give a miss on race tech inlets just from what i have been reading.

I would certainly be willing to make you the runner section if you wanted to try it mate, I'd need to get the sizes and pics of the pulsar flange then jezza can cut me some flanges no probs.
I've been keepin my eyes peeled for an acis mani after reading somewhere that you can work it from parts of a shift light.
What about the tubular Glanza s/ corolla mani, anyone tried this on an 4efte?

Hmm very interested mate, in both the gtir and acis inlets!

Yeh the Jamaican boys have been doing it for a while i think, just have the extend the top bit (plenum) will get the link matey
 
you would be suprised mate, give him your budget and see what says.
my one was expensive because off the bend runners and the shape of it.
 
do it mate:p. the inlet and turbo kit i got is flawless, its so well built, ziscos welding and fabrication skill are the best ive ever seen.:rockon:

also they have tried lots of shapes and styles on their cars so they know what works and what does'nt.

Yeah may inquire into it :D

Silly question to some lol but whats the difference between Individual throttle bodies and carbs?

What would be the best itbs/carbs to use?
Something from a big powered bike like a hayabusa?
I take it there are different sizes, and bigger is better?

So im guessing its as easy as welding (?) the ITBs to a flange off of a 4EFTE/4EFE inlet manifold?

And straight (no bends etc) is better for air flow, so something like the earlier picture Ryan posted?

Dont some ITBs have injectors squirt into the throttle body?
This wouldnt work on the 4e i know.

Thanks guys :)

Carbs would be alot harder to control as they are mechanical so would need professionally set up around every 6-12 months to keep fueling spot on where as itbs run
injectors that can be controlled via managment such as emanage.

Here's a guys project using gsxr itbs

also with the runners on the inlet it all depends what your after (and what space you have to work with) but it's pretty much, short runners=horsepower, long runners=torque.
With itbs the responsivness of the engine would be phenomenal.

Diffirence being, Carbs are mecjanical units, as is ITB's, but ITB's such as Jenvey are controlled with electronics.
Carbs are not, they run on there own basically, feed them fuel and a vacume and they will work if setup right.

Best to use, depends on setup
Again, Hayabusa ones are huge, and possibly a little to big on the 4e
Yes there all diffirent sizes, and No, biger is not better. Bigger the choke, the less velocity through them.
Like blowing through a straw or a hose pipe, straw gives more velocity than the hose pipe.

Most bike carbs are held on with silicone joiners or something along them lines, they need to be or the vibration from the engine froths up the fuel in beside the floats, frothed up fuel doesnt work

Yes straight runners gives a better tract to the backside of the valve, therefor keeping the air velocity up.

Remember the 4e already has 4 injectors, why wouldnt it work ;)

Thats a myth right there
Carbs dont need re-seeting if the carbs are installed correct from the start ;) ie: rubber mounted.
Only time it will need changed is for any modifications to the engine.

.

My choice would be for ITB's, for sheer simplicity of installation.
Carbs take alot of time to setup and get right, where ITB's dont take as long once you have all 4 singing from the same hym sheet.

Ok thanks Alan, seems ITBs will be better for me then, also i will be using the Emanage ultimate for management so thats good.

Thanks for the link, very useful, would not want the bends (silicone hosing) like he used, something more like the picture Ryan posted earlier.

Again something like the picture posted earlier, there wont be that much room, so maybe add a little bit of length from the block, so best of both worlds?

I was running twin 45s on my old mk2 16v gti and if they were re done every year it ran like shit. Not sure on the reason behind it.
