-100% Stock F22B2. About 100k on OEM rebuild.
-Basic el cheapo turbo setup. Gradually increased it to 15psi. Maybe 300whp or a little more.
-2.5 years and about 30k miles.
-No issues at all. No maintenance other than oil changes.
-160psi across all 4 when I installed the kit. 160psi across all 4 before I took the motor out.
-Beat the **** out of it. Street raced with it a couple times a week, burnouts, etc.
-Most reliable setup that was ever in the car. Took it out to do a swap and been through 6 engines/setups in half as many years since then.

^^^ Sorry.

I have had my Holset HX25 for close to 3 years happily boosting 8 psi on a bone stock unknown mileage D16Z6. The turbo was new in the box at the time of install. It only has oil connections no option to run coolant. Best turbo I have had, I don't know what turbo lag feels like anymore.

Why are the Morosos oil pans ridiculous ?

I had built b18c daily driven for 3 yrs. 1yr stock block 315hp(60-1)-2yrs built block 420hp GT35R before I sold it no issues what so ever other than the honey comb in a carsound cat breaking in half and plugging the exhaust. That scared the crap out of me. The car was tuned by T1. Still running strong

Because the oil return lines with manifolds used other than top mounts make the routing a funky. On journal bearing turbochargers, where oil return routing is key to avoiding oil backups, that damned thing caused more problems than it helped. It was welded in the wrong damn spot.

It made people think that their turbos were failing (regardless of company) when they actually weren't at the time. Just a headache

I need to take apart my oil pan this winter and weld all the failing spot welds anyway, and will be installing a new drain port directly in line.

3.5 yrs on that turbo? The block is of no interest.

A quality turbo that isn't oversped, kept lubricated and cooled, and always has the oil changed at the proper interval should last as long as the engine.

I rebuilt my 14B (which I got for free) once, with an eBay kit. It's smoking again a year later. So replacing it with a GT2871R. It's on an 11:1 cast piston/forged rods B16.

Tune it right, and it will run just as long as a stock NA motor.

Drive it right, and it will run just as long as a stock NA motor.

My .02.

I drive it every single day. Just drove it 7 hours 3 states away. Did 44mpg @ ~16.0afr @ 70mph with LS 5th gear.

And I lap race this same setup once a year at Gingerman raceway.

No qualms. Be methodical in your planing, all will be well.

IMHO theres a few things that will contribute to the setup lasting and being reliable.

Firstly that the setup is built properly.

Secondly that its tuned correctly.

Lastly that the owner monitors it and since these cars are open loop, is able to verify AFR and proper ignition timing (aka no engine knock or ping) and know how to maintain the ignition system.


60,000km on my DD so far. Been together a few years. D15b2, 204whp on 6psi, 305whp on 17psi, genuine Garret t3/t4 50 trim.

Do you want me to edit the title to indicate turbocharger reliability?

Would probably clear up what you're looking for

Yeah, change "turbo" to "turbocharger", I think that would work.
Thanks, man

welfarepc...what's that vacuum actuator in the vicinity of your air filter?

How well did you clean it? Also ebay kit..hmmm.
Ebay doesn't always man crap tho, I got a genuine Holset kit from a military surplus dude.

Thread title modified.

welfarepc

Doh, new title makes more sense.

Well, 60,000km on the turbo, I think why is because I run a 5w40 synthetic, and have a good oil drain with a nearly vertical clock on it. No restrictor, -3AN feed. Journal bearing, non water cooled. I beat it pretty hard too, including some multi hour mountain drives. It being a genuine Garrett helps a lot, as well. This car requires zero top ups on oil between oil changes. Usually 5000km (3000mi) per oil change. Might drop 1/2L



The vacuum actuator is a crushed DSM 1st gen BOV. Need to replace that baby soon, its tired.


Edit; my turbo was used when I got it, too... so who knows how many miles are really on it for sure... I am really happy with it.

theYBLEGAL

I didn't really clean it clean it. I made sure the internals of the CHRA were all clean, and assembly lubed. It was a kit from eMotor. I never re-balanced it other than making sure all the components were clocked in the original locations.

I think the point to take away is, genuine Mitsu, Garrett, Holset, etc turbos will last just like an OEM turbo application. I see no reason for the 14b to fail other than it went 12 years without a rebuild, and the only available kit I could find was indeed garbage. I anticipate my Garrett replacement to last at least 5 years, since I'm not constantly beating on it, but do still plan to lap race with it. But, it's being rebuilt with ebay ceramic ball bearing. I'm assured it's a quality rebuild kit this time (wantboost assurance included lol)
