Finally I get to join this club!

My shop finished up the JHM turbo install this morning. It was pretty straight forward, except some mixup with switching the coolant port plug over to the other port. They stripped the plug when trying to remove it and we had to wait for another plug.

I just got home from getting the APR tune and only had a chance to drive about 20 miles in 92 degree heat.



Car pulls hard all the way to redline, and sounds a lot meaner. Love the turbo spool sound, much better than K03.

It was 92 degrees outside and I still have PFR7 plugs @ 0.032 gap. I think that needs to change ASAP for a smoother 4000 rpm and up. I can feel a couple hiccups and timing pull at high RPM, same thing I felt when I ran colder plugs on the K03. I do not attribute this to the tune/turbo at all. But give me a few more days to really get used to it.

So far, loving it....

What plugs are you going to use? My place is recommending NGK BKR8EIX gapped to .024.

Yea that is what is on the APR website as their recommendation. I will probably run those but at 0.026 or 0.028 with the R8 coils.

I asked Daryl the same question and he told me they designed their K04 for stock plugs.

I am currently running NGK7 (holdover from my stage 2 setup) but I have a set of 8's that APR recommends for their K04 kit.

So basically just adding some additional confusion to the thread in hopes someone has a better answer.

I'll keep my other plugs just in case, I'm switching to the 8's and r8 coils.

Keep us posted on your results. I should also add that I have the new revision of the turbo kit as well.

I'm running stock plugs and coils. I want to get the red tops and NGK to see if a difference

When I had my car tuned they switched out my Bkr8eix to the stock heat range plug. Now my car was experiencing a lot misfires during the tune, most likely due to my car needing a carbon clean. The tuner at Force Fed added for a street car without major engine work the stock heat range works fine. I think they put in bkr6e gapped at .022 to deal with the misfires. I have about 3k on plugs now and about to excise said carbon this weekend. I will probably order a set the same the tuner installed as well as a stock 7 heat range platinum.
