Couple updates, install should hopefully be done in the next few days.

Oil pan gasket was replaced, you can see the how much heat this engine produces. While I never had to add oil during the 5k mile change intervals, it was worth it to fix the problem while replacing the turbos. You can also see the ridiculous design of the axle running through the oil pan, not sure if that's a common design among other car makers or limited to BMW.

I have the PI kit installed but don't plan on running for a few weeks till I can tune for straight 93, then get an e25 tune runnign. Once I get those tunes squared away I'll have Trebila help with a 100% e85 tune.

I'll be excited to see what the upgraded transmissions can do once there are a few miles on the kits as I imagine to be needing one in the near future.

Awesome, I love seeing modded XIs

Keep us posted congrats on the GC's. Should make good power!

wtf... an axel runs through the oil pan on the xi? lol

[pits200]

Makes me wonder if the xi takes less oil due to the axle sleeve and differential area taking up some of the space in the oil pan.

I don't think so. It's a pretty heavy duty oil pan and it's massive.

I was confused as shit when I first got underneath the car and saw what I saw. Nice to see work being done on the XI's.

Ya, the visual build quality of the gcs is like no other twin upgrade on the market. Install should be done this Monday but won't be pushing big boost till after 2 weeks of 93 only tuning.

Even on pump gas this will be one fun car!

Watch out for FOD and using the "wrong" oil.

I'm all good, I'm using dollar store 20w60, got a good deal, $1.49 per quart.

Make sure it's non-detergent.

A lot more XIs are getting upgraded recently, its good to see. However that axle through oil pan design is very odd. Seems like a weak spot.

Having switched my wagon from AWD to RWD and the oil pans along with it, the xi oil pan is considerably reinforced where the axle passes through. RWD oil pan weighs about 10lbs and xi weighs in at 17-18lbs.

If you notice people with front drivetrain issues normally break any of the other components first, I have not seen an issue with the pan.

Turbo install is complete, loaded custom 93 mhd back end with jb4. Drove easy for about 20 miles, will give it a few more miles then start with some 3rd 4th gear logs

I have a stock exhaust and at idle everything sounds stock but getting slightly into boost, the sound from the turbos is insane. You can hear how much more air these turbos want to push.

[Jeff@TopGearSolutions]

Good luck with it. Would love some GC's in my xi. Just wish they'd install themselves LOL

[Chris@VargasTurboTech]

Looks great!

[Mario54]

Watching closely!
Best of luck

Put about 100 miles on the car and decided to do some logs as everything seemed to be running great.

Backend, I'm using a basic 93 Trebila tune, it hasn't even had a revision yet. Take into account that I also wanted a very conservative tune at first. I'm using the JB4 to handle boost.

These are literally my first logs and just wanted to see spool characteristics and fueling. I have had a slight surging at very light throttle, this started when I installed my stage 3 lpfp, at wot shows no symptoms of surging.

Current mods
ETS FMIC
AR DPS
JB4
MHD
VTT GCs
BMS Filters
Stage 3 LPFP with fpr and PI(PI is disconnected)

Another Update:

Still trying to get things tuned in on 93. Here is a short pull up to about 105mph and 3 more logs. Started runs at low rpms to see spool characteristics.

So far car has been running great, no misfires, no smoke, nothing. Tune is probably not going to get much more powerful on 93 only.

New logs with pi running a very low flow and boost upped a little. Going to move to an e50 tune here in the next few days, will followup again with logs and videos

Update.

When trying to go over 22psi I kept getting cylinder 6 misfire. Being that I'm on original injectors, I replaced all of bank 2 with index 12. I had new plugs and coils, knew those weren't the problem. When I went to remove injector on cylinder 6 it came out too easily. Luckily there was no damage to the bore and the new injector went in nice and tight.

I went back to my 93 tune and now have bumped it up to 26 psi. The power with awd is honestly comical. I use to love launching the stockers but after feeling how the car pulls at this psi I'm afraid to launch without a 1st gear restriction.

I'll get some logs but I actually need to find a new place close by since my last spot where i would do my pulls feels too short now.

[zmon1300]

Post videos of 93 tune on 26psi. Would love to see how it pulls!
