The three stage conversion was not very difficult, you just need the right tools. I recommend that you have torx bits. All in all the conversion, including installing the new afe intake and doing the aa tune, it took me about 6 to 7 hours. Just be patient and take you time, you dont want to mess...

I cannot, for the life of me, disconnect the four wires running into the manifold beneath the oil separator.

EDIT: I figured out how to disconnect everything, moved all the brackets over to the 3IM, started plugging everything back up, and then realized I had broken the crankcase connecting line.

Dealerships are closed on Sunday and no generic auto parts store carries a replacement. Fun times.

A couple of questions about the parts list:

You said you needed 11617535849 x4 Screw 50x20. Tischer has a complete conversion kit available, and they only supply 2 of these. Any idea why you needed 4?

Also, you didn't list 11617559530 vent hose. Did you not need that?

Also, do you know the torque values for the various parts (especially the manifold itself), and the torquing sequence for the manifold?

Thanks.

Cheers!

This is interesting because I felt that I missed a couple if screws. However I wasn't too concerned since the DISA's are pressed in the and seals well anyways. So I attached one of them w 3 screws and the other with 2... Rather than with 4 and 3 as connection points were located. Seems to work perfect but if I had the option I would get some extra ones so all can be used. Even the way I did it it works perfect though so no need to pull it off! Good luck - it made a fun car even better!

Correct me if i am wrong but this looks like a great starting point for changing your starter. My seems to be cranking slowly and time to replace.

You are correct. And the best part is the starter is the easiest to take out. Uses an E-Torx bit I think was 11mm. Only thing I did different from OP was remove the braces for suspension more room taking out the intake.

good write up OP.
