I love your car so much! It is one of my favorites. I can't wait to see it with itb's.

i'm tuned in.

I should've guessed. Very cool.. I'm going to do some measurements this weekend, you have my attention though! That sounds like my solution if space does prove to be an issue, which I think it will.

Who makes those? I looked into the s14 stacks, they look like they would work but finding them would probably not be very easy.

S14 air horns are great and easy to source as many S14s have gone to carbon fiber air boxes. I have tuned M10 motors and those long S14 airhorn do make a lot of difference in mid range.

My airhorns have been nicknamed the "stacks on Viagra" a decade ago... No need to explain. I have since given the airhons to Roy Hopkins, famous for winning Targa Newfoundland three years in a row with his 2002.

Adapters will fit 45mm DCOe air horns onto S14 ITBs which are similar as S38 ITBs. Just saying... ;-)

Should be awesome if you build a proper intake plenum, and use the right trumpets.

You will have booster clearance issues; space will depend on trumpet/runner length and plenum design.

Either way, if this is done properly, the car will be MUCH more fun to drive! I know you already have a nicely set-up motor, so this is just the icing on top of the cake. :twisted:

Not going to build a plenum at first, just going to run stacks and socks and see how it goes. I will be working on a plenum as a long term goal. No worries though, it'll be proper :)

those itbs are the shit and i need coils in my life.. i envy you :(

[CorvallisBMW]

Pretty cool idea! I never thought of putting ITBs on a bigger, torque-ier motor like the m30; but if you have a hot cam, why not?

WAT!? My Attention --> You have it

[Butler]

Sick!

s14 airhorns. long and curved.

[Jb325is]

Thanks! After looking at it a bit more I'm kind of worried about the brake booster being in the way. Anyone know of hand how much smaller the e21 booster is? If it doesn't clear I'm going to have to look into curving the velocity stacks forward slightly

awesome dude.
