URD supercharger (2.7) long term reliability?

I’ve been looking into the URD kit, but don’t want to compromise the reliability of my truck a whole lot. It’s only got 83k miles and I plan on taking it to 250k+

anyone have long term experience with a boosted 2.7?

also, I read some stuff about people having issues with the URD base-map running too lean. The only tuner local to me doesn’t tune these trucks... is there anything off the shelf that would be good to run? Im in south FL, if anyone knows of a tuner who’d work on a taco let me know.

 

I don’t have the experience but I have the same question. I asked LCE about it and they told me that they have seen many running 8-15 pounds of boost and still getting long engine life.

And when I asked, they weren’t selling a 2TR kit.

 

I'm pretty sure URD gives you a warranty for your engine for 3 yrs. Magnuson does so too.

 

If you're talking about the kit with the Rotrex supercharger, the supercharger will probably break the main shaft long before your engine would be hurt from being supercharged. That head unit is not rebuildable so it the shaft breaks, it ruins the supercharger since they have such tight tolerances. The older ones broke pretty often, but it sounds like they have a newer shaft that might last longer. Do some searches on the Rotrex C30-94 and you should get some good results.

if you don't want to compromise reliability, sell it and buy a 4.0

 

If reliability is your main concern, i would not supercharge it. I just replaced the original 2TR-FE in my truck that had 272k miles on it. The head gasket was starting to go and it was naturally aspirated until i hit 260k. With that being said though, i love the way the truck drives now that it's supercharged. The drivability is leaps and bounds above what it was n/a. Throwing a blower on is a game of give and take though. The extra power will be nice but you can be sure that you wont get as many miles out of the motor as if you'd have left it n/a. Hope this helps some, if you do go the S/C'd route, i would buy an AFR gauge immediately to make sure things are running good after install.

 

They blow up too. My friend lost his 4.0 probably from the oil issue Toyota knows about.

 

if they werent reliable people wouldnt run them.

 

Yeah ive decided to not supercharge for that reason. Id rather have the truck struggle. Its only really and issue on interstate anyways. Around town and up to about 50-60 truck drives fine with 5.29's

 

not true. people turbo and supercharge cars/trucks all the time knowing that it drastically can reduce reliability.

 

that is also true, but those guys aren't running conservative builds. theres tons of high mileage boosted tacos.

 

unless you run a rotrex, those sound like a nightmare

I would like to ask you a question regd his build @Torspd if I may.
I saw that he had upgraded his rear differential gears to 5.29's.
And also has an S/c kit from the info on above link.
I have a v6 3rd gen tacoma, with Bigger tires and I upgraded my rear diff gears to 5.29's few years back too.
After changing my gears to 5.29s' from stock, while I love the drivability, it has limited my truck's ability to go more than 78mph.
My max speed is now at 78mph at 2900 rpms.
Even if I stand on my gas pedal and try to push it to 79, my rpms would shoot past 5000 but truck won't go any faster than 79mph even going downhill.
78mph is my safe upper max speed. 79mph is my final max speed.
This is coming from my true speed indicator, I have re-calibrated my speedometer to compensate for tire size and gear ratios.
Everybody knows by now, that 3rd gen taco's have very poor low end torque and pickup and sloppy gears.
Our terrible transmission are mated with our poor atkinson cycle engine too.
Even gear's shift responses are slow in sport mode, it actually one complete second after you shift gears to engage.
The 278hp Toyota claims for 3rd gen, is only at 5900 rpms. No one drives at such a high rpms.
Between 0 to 60, in automatic drive mode, our truck instantly shifts to 6th gear as soon as the truck reaches 15mph or less.
I also want to add that my truck is at stock height and has no armor or any added weight except the unsprung weight from bigger tires.
If any, I have only reduced weight on my truck (removed heavy factory bed cover, air dam, mud guards and other ground effects).
After complaints from so many new tacoma buyers, toyota came up with a few software patches.
Upgrading our gears to 4.88s or 5.29s are not seen as an option for many of us, it's a necessity. Especially so with bigger tires.
I know some from 3rd gen forum will argue on this.
Many of us folks in the 3rd gen forum have been waiting almost 5years for aftermarket companies to build a S/c kit for our engines.
Some folks have gotten the very expensive ECU update from OV Tune to address their pickup and torque more effectively to get maximum out of this weak engine *(which again in my opinion is the safer option than adding an S/c kit).
But unlike the 4.0, where 2nd gen engine was made with a super-charger in mind with higher engine pressure and temps, our 2GR-FKS 3rd gen engine is not built with such a consideration for higher intake pressures and temps.
Harrop, Magnuson and URD actually pulled back their marketing/sales due to fuel pump issues already.
Before I changed my gears to 5.29s, I didn't realize how often I have went over 78mph.
This was a learning experience.
Especially on open freeways here in So Cal and I genuinely miss that. But going back to stock gears would mean losing the better gear ratios/drivability I now get for my lower speeds.
I'm always rushing and people often give me angry looks it I take the left lane.
I know that objective of an S/c is not always more speed, and that is more about umpf, torque and hp and 0 to 60 times.

Having said the above, (especially my point on my max speed), I have a question:

If the max speed the rear axle/gears could spin the wheels is mechanically limited to only 79mph, what's the point of slapping an S/c kit?
If I get an S/c now, I'd just reach 78 sooner and stay there no matter how much gas I give.

 

Is there a speed cut defeat/speed unlimiter available for 3rd gens? that would allow you to have your cake and eat it too

 

Sounds like your only ways around this, are revert to stock gears (at a minimal cost), change to a different numerically lower gear set, but ultimately get the OVTune. Tuning is pretty much the main way around the nannies.

You'll get better shifting, better throttle response, more accurate fueling, and better timing. Likely even the ability to get past your speed related issue.

 

I debated putting the URD kit on my 2.7. Im local to them, they set me up with a shop to install. I went back and forth and decided to trade my truck in for a v6. The kit plus install would have be around 7k. The power on 2016+ 2.7 is less for some reason... Just didn't seem worth it.

 

I'm waiting for a kit that uses a roots style supercharger for the 2nd Gen 2.7 motors. I'm not interested in a Rotrex.

 

So you said 78 mph at 2900 rpm? Can’t you manually downshift to get the revs up into the sweet spot? I guess I don’t understand.
