Please correct me if I'm wrong, but I thought you were supposed to precision balance a turbo if you take it apart and remove the compressor wheel from the shaft.
That is what I do every time. They balance it at 100+k rpm.
I scored both ends of the shaft so that when I reassembled the shaft the alignment stayed exactly the same as it was before disassembly. This may not be as precise as having it precision balanced professionally but the rebuild kit only replaced the bushings, bearings, retainers, wear plates, etc. not the compressor impeller itself so I’m assuming it will be balanced decently. I’ve checked the play a couple of times since the rebuild and everything seems really tight with no movement. I’ve done everything myself on my build and this another task I decided to try on my own. Fingers crossed it will last. So far so good.

You would probably be appalled at the amount of diesel owners that just blast on an aftermarket compressor wheel with an impact wrench lmao. And nothing bad really happens. Super common upgrade, I always thought that was wild.
I get my turbos (plural) balanced every time I touch them mostly because I do not pay for balancing.
Having said that, I watch the process as the technician painstakingly balances the assembly. The vibrations and associated shenanigans one can witness at various rpm levels on an unbalanced turbo is pretty sobering.

Just thought I’d update. Well over a year later running 18 psi and it still runs great. No issues so far. And I’m not easy on it. Hopefully I get many more miles out of it. Still need to get it on a real track. I’ve done two autox’s but they were without the turbo. I can’t wait to see how it does with the extra hp. Here’s a new pic just for attention.

The JR19's Exomotive sells are perfect for a wide tire street setup. No spacers needed and you can run the 275 AR1's or CR1's when they become available.
looking for insurance for Exocet for value....any ideas?
Collectors car insurance via American Modern Insurance. It's based on agreed value (you tell them how much the car is worth if there's a total loss), how many miles you drive per year, will it be garaged, and your coverage options. My $25k Exocet + my $10k BMW 135i were (together) about $700/year with 2k miles each and a $1k deductible each. I'd have to check how much just the Exocet was by itself but you're probably talking $400ish.
I had American Modern and accidentally let it lapse (got a new credit card) When I got everything sorted out they said they don't insure Exocets anymore so I went with Hagerty. Since then I've read that other Exocet owners have signed up with American Modern so I could have just gotten a lazy insurance broker.
Oil cooler install. I’ve always ran oil temps around 210-225 around town in the Fl summer heat which is usually around 95-100 on the hottest days. I jumped on the highway to go south to St Pete for a 45 minute drive. I settled in at around 85 mph and saw oil temps start to creep up. I got up to around 260+ once I got to my exit. I was concerned it might keep going higher if I pushed it harder. I want to track this thing eventually so this prompted me to go ahead with an oil cooler. The temps I saw are borderline acceptable but I wanna make sure I can keep temps in control once I do a couple of track days at Sebring next month. I decided to do an install behind my front splitter. I made some slots so I can adjust the cooler so that if I want to I can tuck the cooler all the way behind my front cowl. The cooler is halfway poking out at its most exposed position. The install was pretty straightforward but I had to replace my sandwich plate with the supplied sandwich plate which didn’t have enough ports for all of my gauges. I used a AN fitting with a port hole and that works fine. I’ve only done a couple of 30 minute drives so far and temp outside has been in the 80’s, not the high 90’s that prompted me to do the install. Temps are about 10 degrees lower just around town. I haven’t pushed it yet but it for sure is doing something.
Hey...Not trying to be a kill joy here, I like the oil cooler a lot, but if you are planning to track your car, you may want to mount your oil cooler to some thing else other then the splitter. If (let's be honest...it's really When) your splitter gets hit and rips off that oil cooler is going with it and that's going to cost you a lot more. Cost of replacing the cooler / maybe engine and the cost of paying to have the track cleaned off of oil.

No, that's a very valid point. I'm going to drive it around for the next few weeks and see what results I get and then see if I can relocate before heading for a track day.
