I purchased my 2008 E92 335i about two years ago now with 60k on it. At 66k I installed the JB4. Then ISO and went FBO w/ E85 minus meth until 140k. Being very happy with the car and knowing that I will keep it for the long run I decided to jump all in after my SPEC 2+ clutch gave out in only 7 months!

I scored a good deal on a used N54 head that I decided to clean up and send of to get the works done to, full p/p and radius'd, values cut and lapped, balanced new springs, new seals,etc ...(minus larger valves and lighter springs/retainers). Once I got the head back I cleaned up the combustion chambers and sent them off to get ceramic coated along with my pistons.

Dirty vs cleaned up combustion chambers:



Ceramic:


Now began the real work!

BMW TIS was used and printed out for all procedures and torque/fastening values (nm/in/lbs/ft/lbs). All Torque to Yield bolts were ordered new and the old TTY fasteners thrown out.

I managed to get the car as high as possible on jack stands and get the transmission pulled out.



At this point I was torn between going with upgraded twins or an appropriately sized single and wouldn't you know mjmarovi just so happened to be selling his Proven Power Single kit with the Forced Performance HTA3586r Tubro! We worked out a deal and I began pulling my stock parts send his way in the exchange. Just a quick aside... I wanted to give Matt a big thumbs up here as he was extremely professional to work with and I had absolutely no issues staying in communication with him at all with every txt msg, email, phone call. He was 100% honest with me the entire time and I would do business with him again in a heart beat, no hesitation! He even helped me troubleshoot a few issues along the way!


Removing the stock turbos:



Look at all that space!


Valve cover removal:


Time to pull the head. Having most of my experience on the Chevy LSX platform I decided to do due diligence on marking the way everything was positioned prior to removal. I love white out :) Notice the special BMW Timing tool used to TIME the cams later on. (Note: This tool will only TIME the cams, you will need an additional special tool that is impossible to find and costs about 1k to INSTALL the cams). I found this out much too late and wanted to bring it to your attention.



Heads off!


With 140k on the clock the cylinder walls look amazing considering what I've put it through. Look at that cross hatching!





Cleaned up head gasket surface:


Ceramic Pistons Installed!!




Time to re-install the head!
Remember that Cam Install Tool I mentioned earlier? Well it allows you to pre-tension the Exhaust Valve on Cylinder #2 and Intake Valves on Cylinder #3 along with aligning the cam bearing shells properly:






When installing the cams make sure your rockers are sitting on the valve stems properly:


Lets protect the VC from the new single manifold heat:




REMEMBER to CLEAN OUT ALL THE HEAD BOLT HOLES prior to installing the new head bolts!!! They must be free of debris and liquid or you could crack you block in half!!!


Finally Lets Get some Turbo Pics!
