Excuse my ignorance I'm old so I do not know these things. But what is the IAT sensor and could you put it under the air cleaner instead of through the top?


Intake Air Temp sensor. It can be anywhere in the intake system. Wherever it fits.

Intake Air Temp sensor. Dunno why it's out the top either. Might be that there isn't enough room to put it in from underneath...

Yea I couldn't find a spot underneath that would fit without interfering with other parts. Also I figured that if there is any condensation buildup it won't pool and mess up the sensor.

I came here from another forum with a similar build. I'm very inspired.

Do you have any updates?

I have a similar thread somewhere, I need to update it as well...and get back at as the project is 98% done.
I'm done right to the airfilters, but I'm having fit issues on one side fuel rail, just because it's going into a VW bug.

No updates lately. This project has been shelved for the near future due to loss of the shop I was working in and a promotion at work that has been a drain on my free time.
I slapped a pair of carbs on it for now and boxed all the ITB stuff up for a later date.
I will get back around to this someday but for now I just want to get the car driving again.

Thanks for the interest and if you have any questions please ask away.

Bummed you didnt get a chance to finish, this is exactly what I would want to do if I have a FI flat four.

do you have to use the EMPI manifolds to mount these or will any Weber manifold work? I think the spacing is the same on the weber carbs so it shouldnt have to be but I dont know for sure...

I was interested in these working at all. Fun project....understand completely time constraints.

Different set up than the MS with the D-jet components.

This is a cool project, but I think that you are going to want to rethink you throttle linkage. It is going to really screw with you on idle speed.

Air cooled motors grow when hot, and the Type IV can grow somewhere close to an inch in width from cold to hot. That is gonna change the length required by that cross rod.

It also explains why the linkage on a 911 engine looks like it does, with the crossbar that pivots.

A whole inch???? (IMG:style_emoticons/default/huh.gif)

I think that's stretching it a bit.

I think that's stretching it a bit.

I got about 1/2 inch from a full blown 13:1 race motor.
Made me change linkage.

A stock motor moves less than 1/4 of an inch.

And yes, I have measured both race motor and stock....cause I was curious.

I also have owned every cross bar linkage made, and a few of the center types...
Ended up with Foleys cable setup.

I even designed a cable setup...

The motor does move, and cable linkage is the best answer.
