    Right after I bought mine from JMTC, they told me they were changing their ICI pipe fabricator --- possibly 'cause I crabbed about the way the WMI port was added. Also the built-in "dent" to minimize an interference fit, is in the wrong location --- there's serious interference! Arric probably couldn't find another source to fab it at a reasonable price --- it's a really tight fit, with a couple critical bends.

    I suggest you take your car to someone that works with pipe, and have them custom-build one for you. Performance gains are noticeable on the butt dyno, plus Arric had a chart showing the HP gains, but it probably went away with the pipe.

    Sorry for the delay - just picked this up.. good suggestions, I'll need to try and figure out how to do that (i.e. suggest adding pic of Dyno charts.. etc).

    Also - love reading this build thread... making a list of items to check on mine. Since I didn't do the build, I'm going to have to do some investigation (and question asking for Mario).. good stuff. :)

    Long overdue update --- Mid-March 2018, I was out troubleshooting a P28AA DV error (I'm using an external BOV / DV). In the middle of a hard accel, bang crash etc. --- it quit! After about a mile long AAA ride home, lotsa pissin' & moanin, then some rooting around under the hood, I found the center crank bolt was loose. Seems that during my last build, I used the old spec of 50Nm + 100 deg, instead of the newer spec of 50NM + 180 deg. Tear-down --- found all 8 ex valves stuck open and some lifters loose in the valley. Pulled the head and found minor piston damage from valve contact. Decision making time --- rebuild or part it out! Spent several months throwing money at the spouse, home, and family travel --- went too long focusing on the Mini. Early 2019 I decided that if it could be rebuilt for under $2K, I'd do it. Sent the head to my tuners head guy for valve replacement (I don't have the correct valve puller) and he found all intakes were also slightly bent. Head work, gaskets, couple tools, etc was just under $2K.

    During re-assembly, found the DV / BOV was "frozen" closed, that's why the code. During re-assembly and talking with a few others, about the loose crank bolt, seems there are others who had similar issues. One of the guys developed a bolt "locking device" that should keep it from working loose, so I obtained one and installed it --- cheap insurance.

    Anyhow, it's back together, got about 500 miles on it, and had a dyno pull last week. Picked up about 15 more WHP and torque is now over 400 ft-lbs. Been awhile since I added pics so here's a few more ---

    @oldbrokenwind where do you get that crank bolt lock? That is a must have item.

    FYI - I know this is a long time coming. I had been trying to figure out a way to do this correctly.... finally to a point of hiring someone to do this. Still 1 - 2 months out for completion. But assuming the price is reasonable (should have quotes next week).. it will be done along with some other things similar to a leader board etc. :D

    Agree - where can we get said part? I didn't know that was a problem with these.

    Contact [email protected] --- designer and source. Note that it can be installed WITHOUT loosening the crank bolt.
