Realized I didn't include these so here's a few photos of the ethanol and fuel pressure sensor installation in the engine bay.

Just a general overview.


Little closer shot of the 5/16 to AN6 quick connect adapter.


Here you can see the ethanol sensor on the left and the fuel pressure sensor on the right as well as the 3/8 to AN6 quick connect adapter.




And with it all put back together.

Amazing Tigger. Im always learning from your threads
We took Turbo in for what felt like nebulous slipping in the drivetrainunder load. We were hoping it wasn’t the clutch again (it wasn’t). No cel either. Took it to our Mini service Dept. Turns out the coil pack for cylinder #3 was going bad (about 56k miles). Fortunately, everything was covered under warranty. Turbo was back to running like a champ.
Low and behold a month later (this past week) we are getting the same feeling again. Are OEM coils that unreliable? Are Ignition Projects coilswhatyou’drecommend as a reliable replacement? (I’ve done zero coil research).
We’re taking Turbo in Tuesday, and I’m going to ask them to replace the remaining original coils if that is indeed the issue. Gota have everything in order for the drive to the hospital.

Generally speaking the factory coils are very good units and pretty reliable. But like any mechanical or electrical device they are subject to failure. For stock boost levels they work great. The energy level is a little low when you start raising charge density, especially when adding meth. The 0.024" gap of the NGK 1422's helps with that. Another reason we recommend them. So for most that combination is sufficient.

Where you start to see a difference is at higher charge density and higher rpm where the coils have less dwell time. Thats where the IP and Okada coils start to show a small benefit. At 6800 to 7000 rpm you won't notice a single misfire or even multiple ones since each cylinder is firing 56 to 58 times a second. The Okada branded ones in my opinion are too expensive for the benefit. In addition, the lower priced N14 IP coils work just as well in an N18 application as the N18 IP coils but at a lower cost. Since the Mini N18 and N14 coil part numbers were the same I ordered the IP N14 coils for the N18 with no issue. Also, since I'm running meth with 25 lbs of boost, and planning on more later they make sense for me.

One item of interest to note is that Mini updated the coil part number in July of last year. As of yet I haven't heard anything about what Delphi may have changed though.

I love this thread.

What did you upgrade in the engine to run 25 lbs of boost?

Right now the only internal upgrades are the ARP rod bolts and head studs. I'm running pretty safe timing up top and bring the Aquamist in fairly early as well. Since he's my daily I have to make sure he stays healthy while I tinker with the builder motor.
Tinker as in "Save my pennies and buy stuff without the wife noticing."

Nice! I want to push to 25psi. I'm Manic Stg. 3, Map C. I want a little more out of the car. But I'm sure I'll need the meth/water injection. I may just do water injection, if that's good enough to control temps.
