sorry forgot the OBD1 system is called Motronic M2.9 (M2.9.1 for engines with coil pack), and OBD2 is called Motronic M5.9.

UPDATE:

The car has been finished. It made a trip to the dyno and made 153WHP/134WTRQ. The engine's throttle response is amazing. Very snappy, very cool sounding.
I will try and post a video later in this thread.

so how you fixed you idle problem ??

 

[doppelfaust]

Okay so,

I have done about 3hrs. of research and a friend has also helped out. And we came up with this.


DOW CORNING MOLYKOTE 321.

This is used by FORD and Mitsubishi on their throttle bodies. They say to never clean them! If you do clean them, then you need to reapply this stuff to the butterfly/bore. Let it dry and crack open the butterfly, adjust your idle stop screw. Enjoy your low idle setting.

I will install the manifold in the morning along with the new phenolic spacer. (helps keep the fuel rail cool) I bet with the stop screw out all the way, it wont start. Screw in the stop screw until it idles.

:beer::thumbup::beer:

After allowing the MOLYKOTE 321 to dry over night. I slowly cracked open the butterflies to break the now all closed position with the idle screw out. It started right up and is idling at around 850-1000 rpms. I didn't have much other time to play with the MS tuning today, but will in the morning. Made a dyno appointment and I will report back then.

"candm" came by today with the TWM 16V mani's. And they look really nice and simple. Now I'm starting to mock up a set up in a rabbit.

so how you fixed you idle problem ??

Did you read the previous replies? Sounds like he had air leaking past the butterflies and used the DOW CORNING MOLYKOTE to make the butterflies seal better.

Made this mistake on a 4G64 Evo VIII build. Chased my tail for 2 days on it.:banghead: Dow 321 is good sh1t.:thumbup:

Out of curiosity what are the specs on the motor? I have a similar setup and could never get it dialed in due to breaking stuff. Runnin 48mm throttle bodies and 298 cam and other stuff.

 

[simon-says]

The engine is a hybrid.

9A bottom with a Cross-flow head. 276 cam with springs. 11.5 comp. JE pistons. Port and polished head. 1mm over sized valves.(supertech)

The car is coming back in to my shop for some suspension work. I'll take vids then. Stay tuned.

 

[eurotrashrabbit]

Um those are the specs of my motor? Except with 2mm oversize valves and scat rods. I also converted over to a 16v oil pump and ditched the dist

 

[simon-says]

This engine doesn't need rods, just rod bolts. And I used the distributor to run the 4 window hall sensor for the sequential fuel injection.

Video?
