Thinking of installing jb 3 plug and play on my e93 6mt. Will this increase my chances of turbo going bad or other engine issues. Currently I have about 50000 miles and the original hpfp. I would love another 80 horsepower. Is this my simplest and safest upgrade?

Well you are raising the boost, so yes there will be more ware.

i probably wouldn't really worry about engine failure. I'm positive the N54 can handle another 80 hp without any problems.

yeah the block can, not to sure about the turbos, fuel pump etc.

I have it on but i keep it in map 0 and turn it on only when im feeling naughty (lol) as long as you dont beat the crap out of the car every day, you should be fine.

There are quite a few people with >50k miles on their heavily tuned N54s. Shiv's car i'm sure has seen better days from all the hard testing he does, and I know MR.5 is pushing north of 70k miles and I haven't heard of any chronic issues out of him either other than some broken vacuum lines.

I know clap135 has almost 40k miles on his 135, and he's not exactly gentle on his car. I have about 29k miles on my 135i in less than two years and it's fully modded, seeing upwards of 19psi some days. My car still runs like a champ.

[cu_north]

I'm about to hit 50k with 43K Tuned, so far so good! I pretty much drive it like I stole it all the time. No hpfp problems or turbo problems, fingers crossed!

[dzenno]

Close to 50k miles here and no engine issues to report...had 1 fuel injector replaced ever...i did however manage to break one of my halfshafts due to wheelhop on a hard launch with sticky tires on...you'll be fine with it..

[Mike@N54Tuning.com]

There are millions of tuned miles out there and no real issues. JB3 on map3 is a great and reliable tune! Just grab an intake as well and then you can go up to map5 as long as you have 93 octane. The tune will definitely put a smile on your face every-time you get into the car.

As long as you maintain your care properly you'll be fine. Just don't be a JB user who starts creeping up the maps as time goes on. I don't want to hear about you trying to figure out why your car is throwing codes when you're running map 9 with 93 octane (basically what Mike said above).

[techlogik]

Of course the biased vendors are going to come on here and say it is all cool, sure, just boost the turbos past their designed limits...nothing wrong with that!!! That is how they make money...they don't care about your warranty and engine, if they do, it is only to a very limited point...but you are on your own.

Anytime you start running a tune on a stock FI setup, the chances are increased of issues related to such....so don't be surprised if something happens.

Any vendor that says there is no risk and you can run your car like that 100K and expect zero problems are liars...that simple.

This same kind of "reassurance" used to be done in the Audi/VW world with K03 turbos. Ohhh..it is fine..sure running 19psi on K03 turbos are cool.

Well, come to find out the hard way...the K03 turbos all started letting go, it was just a matter of time before they went kaboom, guaranteed. Anybody that was boosting Audi S4s back in '00-'02.5 knows that story and line. I know these are different turbos, but the limits they were designed to operate were not at 16-19psi. Of course, it was a great opportunity to put K04 turbos on those cars relatively inexpensive that blew, then run 22psi!!! If you don't care about that, and when there are vendors offering single or upgraded turbos for few grand, Great!!!! Have at it.


Cliff notes:
Run tunes at your own risk. When something goes wrong, they tuners aren't going to be there for you.

Engine shouldnt be too much of concern on a tune only car.

But your are pushing your turbo's more, and things like fuel pump and injectors coilpacks ETC (any of the weakest links this car is known for) on this car will be tested. So be ready.

Well said, +1. Basic bolts ons will help alleviate stress on these "weakest links" that jpslick mentioned above.

[kennejp]

Like many others have said, yes it will put some more wear on your car/turbos but nothing that the car cant handle. I cant tell you how many people have tuned cars that have been that way for years that get beat on and the cars are fine. Do it and enjoy your new power-you wont regret it!!! I like you thought about all this and was weary of doing it now I couldnt imagine the car without out tune and mods.

Wow... I don't think any vendor, myself included will tell you there are any guarantees. I can't guarantee a stock car driven by my mother will last 100K, so I don't think thats a reasonable statement.

I think every tuner will agree that 13-15PSI is the sweet spot in terms of power/reliability ratio. Just for perspective we have guys running 20+ PSI on the track as an extreme example.

I think it would be interesting to know if there have been any chasiss issues with widely tuned cars which have seen higher mileage while being tuned.

[GarageKeptE92]

If you walk on carpet, more and more, its going to wear out. Everything in life wears out with more use. Now, take a car with more power and more heat produced, eventually things will wear it exponentially. Not saying over-night, but its certainly not healthier for a car too push turbo's and add more power the vehicle and assume its going to last longer.
The question will be how long do you plan on keeping the car and are you ready for the consequences if any ever. There is a strong suggestion that these cars can handle it.

[themyst]

downpipes ease the biggest point of backpressure, an upgraded FMIC will lower the amount of effort necessary for the turbos to hit their target, and an intake will help the car breath easier, especially at high boost levels.

I honestly do believe bolt-ons will actually extend the life of the engine due to the lower stress components are put through. boost level equal of course.

[Jeff@TopGearSolutions]

I would be inclined to agree.

...which absolute boggles the mind because the stock turbos loose a major portion of their efficiency at 16 psi and over..

Yea on pump gas stock intercooler.....

Not methanol, Race Gas, Intercooler and full bolt ons.

Numerous dyno charts prove otherwise.

Those do nothing to improve the natural efficiency of a turbo. Well, maybe the bolt-ons designed to help it breathe (a little).

Those other add-ons only serve to adjust for the increased IATs of a turbo pushed past its sweet spot.

N54 stockers pushed to 20 psi in the high RPM range are SCREAMING... for help.
