Coming soon to Guten ITB's...

[SamE30e]

I don't see the M5x and S5x ITB's on the site. Do they exist?

[nmlss2006]

The biggest change you're going to see is in responsiveness. After that would come flow at high RPM, but a lot of engineering has to go into intake runner lengths and plenums to avoid losing too much torque lower (think S50 vs. S52 vs. Schrick manifolds...). Let's see what is actually available :). I am not, however, sure that Emre's Option (B) would produce good (read: better than stock) results easily. There's a lot of testing involved and a fairly extensive knowledge of fluid dynamics. My hope is that the gentlemen at extrudabody will put their expertise to work to produce a complete set, at least mechanically.

ooooohhhh I just jizzed in my pants while imagining a euro hi-comp m30b35 with 533i flywheel and ITBs.....

Id much rather have the extrudabody setup, but dbilas has an itb setup that uses stock Afm, TPS, and is bolt on. That is quite appealing on its own.

comming from someone who has Dbilas, while they do have it as a bolt on with stock stuff, it is much better with a MAF conversion, but BEST with MS and a MAP conversion, wasted spark ETC or a STAND ALONE to get the most out of it.
that is my next step, ditch the MAF conversion with piggyback and go EMS of some sort. either MS or depending on cost extrude's EMS.

would like more info on their set up as far as cost, support, and plug and play or make your own harness.

if someone buys these, i can give them the dimensions of the airlog and runners if they need to make their own.

[der affe]

oh and Dbilas does offer an intake mani ($950) for the M-30, BUT you will need to make your own airlog and fuel rail (custom). that kind of turned me off to that idea, if i did an M-30 swap, and i can do all that myself.

I've been waiting to see something for the M/S5X so will stay tuned.

Kevin and I have been working in conjunction to make his ITB's work for Forced induction and for BMW's for over a year now. I am also a dealer... as well as the fabricator/R&D guy. FWIW. The benefits have been overwhelming. One of the main reasons my car makes so much more power than any other typical setup like mine is a direct result of the airflow capability of the ITB's.

[Massive Lee]

Mid range torque will be gained by the simple removal of the AFM. And torque will be lost from the reduction in length of the intake runners. Any dyno figures on the subject?

[aproy]

oh yea?!

[Massive Lee]

oh yea?!

Oh yeah.

[vcsg1]

would like to see something for the m42 as well...

[bimma360]

I'm all ears.... i'm already gonna go standalone (Dederic Motorsports), so sounds like this might be the next step. Good work Levent!

I want this too. Please...keep us updated. If they are as high quality as dbilas, and less expensive too, then I'm in for sure! My m42 could certainly be more responsive.

[z31maniac]

I'd like to see M42 stuff as well.

I'm already researching a high RPM bored M42/M44 for the slicktop.

[///digitalme]

m42!!! hopefully something comes out for the m42 im highly interested
