Building a 2GR-FKS for max power and reliability

Do you have this in writing? If so, congrats. If not, try to get it in writing.

They fucked up. Contact corporate.

 

A titanium valve train. What does that even mean? Intake valves? Rockers? It would make zero difference on a 2GR engine unless it was revving to some absurd speed.

If you want to increase durability and reliability close or semi close the deck and prevent oil from pooling/getting ingested in any significant way. Those seem to be the two failure modes most common around here anyway.

 

titanium moving valvetrain parts. intakes, exhausts, rockers i think but am not sure as i looked into it maybe 3+ years ago., but when i looked into it i think it was the maker who claimed these percent improvements in response mainly due to the weight reduction in moving parts. i have no experience with it personally so maybe skyking3 will chime in.

 

Titanium exhaust valves are a full blown range engine thing. They do not last long. Maybe some sort of moly/ti alloy works be in like a supercar engine, but even then they would be basically a wear part. Anyway, until you rev high or have huge valve displacement dimensions titanium parts offer no gains because the heavier steel/ss parts are not the limiting factor.

 

Exactly what I told the head of the Service department, to which he responded
“This engine doesn’t work like that, a quart of oil over wouldn’t matter”

 

You would be correct - if these were traditional titanium valves. However, Toyota began development of these powdered metal/sinter forged Ti valves back in the late 80's, and had an exhaust version in a production engine by 1998 with the 3S-GE BEAMS Engine.

The next engine to receive them (that I'm aware of), is the Lexus F car 2UR-GSE engine. 1st gen got Ti intake and high nickel exhaust similar to 21-4N (8N, inconel?), 2nd gen gained the Ti exhaust, too. These are a drop in for the 2GR-FKS as the engines share architecture. Lexus sells them for stupid low prices... so we get to benefit!

@BMcCade these valves should be your go to if you end up building something.

 

These will definitely be something I look into
Thanks for the quality input!

 

Really appreciate the quality info & breakdown. You wouldn’t by chance have a link or part # for these AWSOME valves would you?

 

If it didn't work like that, there wouldn't be a minimum/maximum capacity.. of course we know this, he knows this, and you know this. Your story absolutely sucks, and I hate it for you, because I doubt you'll get any resolve without being the one to pay the price, even if you went the legal route. Considering its out of warranty, I don't think you'll have any luck having them eat the cost of the mistake, even if they did for some magical reason accept fault. I honestly think your best bet is to get their admittance to overfilling in writing, and try your hardest to escalate up the chain of command sternly and respectfully. It won't result in a free engine, but if you're planning on buying it yourself already, it wouldn't hurt to fight it as best you can to hopefully reach some sort of "discounted" agreement. That absolutely sucks.

 

Very much agree with this here. If you can get some sort of documentation and take to a Toyota regional manager and say "Dealer says this can't happen due to them overfilling my oil. I believe it did (foaming, pump gulped air - bearings shot). What can you tell me? Is there any policy coverage help?"

I worked for Peterbilt and dealt with several OEM suppliers in a past career. Often as a dealer we'd go to them with bad situations and ask for help. CAT was amazing in this regard. "Have them pay for the extended warranty and we'll pick up the parts" or "we'll pay 40% of the labor" type of help from the OEM. I'm talking they'd give help on engines that had a head gasket go at 800k miles. Cummins - not so much.

You're not going to get this from the dealer but if Toyota USA's regional guy says "yeah, that's basically what happened, dealer messed up" - you can then ask them to help you with the dealer on such a thing.

 

Ti intake 13711-38050
Ti exhaust 13715-38090
Stainless exhaust 13715-38080

 

Then why is there a 'Maximum' fill line on the dipstick and warnings about not over-filling?

 

They're just telling him that because they are a bunch of weasels. It's no different than when you have a warranty claim and their first response is always "I've never seen that before". Like my white paint oh that never happens! Except for the three we repainted last month of course.

 

Why do dealers need to be so scummy?

 

more money in their pockets.

 

I think they would make more money by being the good guys, and not a place people want to go less than 4 or 5 times in there lives. I don't want to give the dealer a single cent of my money and I'm not alone in that. I might actually want to have service done there if they didn't foster an environment of distrust.

 

Understood... my post was actually written in Sarcastica font!

 

their mistakes cost money. if they can get out of those mistakes and pass the bill to the owner (and most are none the wiser) they will do it.

 

The problem is people are becoming the wiser, this is the information age, the news is out, dealers suck. They need to improve there reputation or they won't last long.
