e30 m30 + OEM ITB test fit

[325ix]

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

Needs moar videos including speedo shot.

I will get more videos after the ITB's are done.. I need to figure out this misfire and do something about my exhaust first. It has some shitty perforated tips on it right now and it sounds wayyyy too raspy.

[Huff]

Those ITB's are pretty long... You think with the horns (any size), you'll be into your brake booster?

Depends on the angle when they are bolted up, but yeah, probably so. I have roughly 11" of clearance in a straight line from the intake port to booster, probably not enough for adapter + TB + airhorn + filter. Chances are I will end up having to go with the s14 horns or something similar. I would consider swapping boosters but I can't seem to find any info on size differences between stock and e21 boosters though

I believe the ix booster is smaller, but what about slotting the firewall and sliding the booster over? That may gain you just enough space.

Also what are you running for exhaust? I couldn't find anything in your build thread.

Who makes those? Guess...

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.

My 02 with the horny horns.

Looks like a nice set-up, but what happens when all the air in the engine is hot, and heat soaks the intake temps? I'd imagine the car would do even worse then the factory plenum and intake... :???:

^^^Racecar. Air is fresh under the hood when car's in motion. Lots of opening rom the front.

I'm down for some updates on this project.

[BrownBeanE30]

more please :)

[stinkydriverx]

depending how this works out. I might have to do this. Although cali police don't like ITB's too much.

[be34st]

Yup subscribed.

Yeah the e30 has been on the back burner for a while, I am putting together another e34 and I can only do so much at once. Just got hooked up with a new machine shop though a couple weeks back so I'm planning on having the T-stat housing done soon then figuring out where my clearance issues will be

In related news I think Paul Burke is offering TB adapters that require a lot less port matching than the ones I have as well as a better design for the bottom hole

[grippymonkey]

I like it!

Any more updates?
