Finally made and installed a working itb setup. Should get it dynoed some time this summer.

Some short clips, before and after.

Are those the 42's you were talking about?
They sound really nice!
Aside from the really low RPM stumble on the last vid, the throttle response is damn crisp!

Motorcycle TB's?

I assume you're going to eventually go turbo with this set-up?

Yup, just took forever to get it done, and the intake design changed many times...

They are 4*42mm tb's from a Gsxr 1000.

I have changed injectors so the map is no where near where it needs to be, could not even get it to rev above 3500-4k because it drowned. Will fix it this summer, and get it on the dyno. Realy looking forward to hearing how it sounds under load at high rpm.

I'm currently finishing up my second year of my three year mechanical engineering degree, so turbo will have to wait untill i start getting some paychecks.
Planning on fabricating a plenum next, so i might just have to make shure it will be strong enough to handle boost in the future. Only issue would be to fit the turbo, the runners on the itb manifold only have a 30 degree rise, so the turbo manifold would need to extend almost to the radiator.

Before i mounted the itb setup, i modified the exhaust somewhat, to get it to not make my ears bleed.

Improved the Y on the headers, wich was a heavy, ugly pos hack job, welded with the worst mag welder ever created, and replaced it with just a vband, also made and fitted a vband and compensator to a new muffler. I don't have pictures of the rear muffler, but it is a RB turbo muffler i got from a friend, and it is way better than anything i ever had before.

Some videos, before and after. No rear muffler on the befor vids, gave it to a friend who wanted it on his rx8.

Got the stock camber link, Toe rods, front swaybar link and rear sway bar link into the computer, considering making my own adjustable ones since it seems like it would be a fairly easy project, and much cheaper (and more fun) than buying the ones available.
I should be able to make all of the rod's for less than the cost of toe rods.

Toe link drawn up like all the other aftermarket ones i have seen. But it seems the stock rod is designed to avoid to much of an angle on the balljoints, and this design on the adjustable ones seems kind of lazy and worse than the stock setup.

So i think i want to make my design look more like the stock one than the aftermarket ones...
