S550 Coyote OPG failure conditions?

[JZA61]

Heyo,

I'm a prospective buyer, and am pretty much settled on an S550 GT (15-17) as my next drift platform. Ive been at it for a long time, though out of around 20 cars, most have been Toyota/Lexus aside from the occasional Datsun.

My biggest concern is the oil pump gears, but I've read a lot of mixed things. Sustained high RPM runs, 500+whp, oil starvation from track use or thinning of oil, high mileage, ect. I'm a Toyota technician so I get that failures can happen on just bad luck, but is there a safe parameter for drift use? Having to crack the motor open the day I buy it is dissuading, even if I only gotta do it once (or pay someone who's done these a bunch to do it). I know S550s are among the rarer cars at drift track days, but I do see a small community out there, they just talk about power adders and suspension instead of keeping the motor alive


I don't plan on adding a lot of power, just exhaust and possibly an intake, as my normal "mod kit" is removing weight, lots of suspension, and reliability such as an AOS/Oil cooler/rad ect, these Coyotes make enough to party as is. While drift isn't as hard on the motor over a day as say time attack, it's still not nice to it lol

The common denominator in failures is riding the rev limiter.

Yeah, it's not so much that it's really unreliable, it just doesn't like lots of shock loading. Either from a supercharger running off the crank snout, or bouncing off the rev limiter. For a drift car I'd definitely do them and run a 5w40 or 5w50 weight oil. Do both of those and I don't see why it wouldn't hold up for many drift miles. You may also want the GT500 valve covers for better baffling.

Thanks! I ended up picking up a 17 with 30k. I'm guessing I should only run the 5w40 for the duration of events and switch back for daily use? I'll grab the gears and have them done

Ahh didn't see this till now, otherwise I would have brought a GoPro

Ended up going to our local event yesterday to see how the car feels in stock form. Only things on the car are a Magnaflow that came with it and I deleted the rack limiters, so suspension and angle near totally stock. My brother took a couple videos on his phone, the last in car one was his first time in any sort of aggressive driving so he was quite animated lol, that run was also in the morning while I was still driving conservatively to feel out the car.

I'm honestly kinda surprised how well it performed in stock form, can't wait to throw suspension at it. Only casualty was the ebrake cable underneath on the driver's side broke, ordered a replacement already only a $30 fix thankfully
