Advice for all of you considering a custom turbo 540

Its been something huge for someone to turbo a 540i. Unless you have a ton of cash to throw down the drain, a secondary car, and a lot of time, and experience i would not recommend it to anyone. Not gona lie the results are insane and adjustable boost at the touch of a button is something else. But its been one thing after another with this. If you want to really push get a supercharger. As ive seen from a few of you the vf seems to be great. The project will be concluded tomorrow to get it running (perfect). With the amount of money you spend on it you can very easily get an m5 or basically any performance part. About 16k later not including the price of the car and a lot of hell to through trying to get things to work yea its about complete. If you want extra power just get a supercharger unless you want to go crazy with it. These cars are crazy as it is. And supercharged just insane. More then enough to take majority of whats on the road. So yes its been done. But in conclusion I must say its almost not worth doing unless your willing to pour money and time into it. JMO

Aren't there

Several turbo'd 4.4l from BMW right now(essentially the same motor)...seems you'd not have to reinvent the wheel. Yep you'd have to spend some $. But either way you're gonna spend some...IMHO

The 550 and X5 come to mind...

The only thing the the m62(b44) has in common with the newer n63 engine is the displacement. Two entirely different animals.


And Iceman, didn't everyone tell you that already?

Tranny should bolt up...custom mounts? I mean there are hundreds of swaps with LS1's and that would probably be the best way to go for sheer power per $. I am sure with any level of ingenuity this could be pulled off, or do an LS swap easy and cheap power...

Yes I was told. I've seen a few turbo 540s out there. All have different set ups. Tried making mine as sleeper as possible under the hood. Finished product is great. Once everything is cleaned up later this week I'll post pictures. Been hectic but sure is cool at this point just happy with the conclusion.

The hardest part was synchronizing everything and the computer work. But I took it further than that. I now have a built engine. Went and got an engine with 40k miles on it and the shop built everything on it from the inside out to handle the power. Your correct, there could have been an ls1 put in there. Next project is suspension brakes and rims. Not too worried about the transmission at this point. When the time comes and it will come maybe I'll do a conversion on it. Everyone told me it wasn't possible to turbo an e39. I like the way the 540 handles. Couple of you were telling me how the m5 has better power and interior. I don't understand it. I had a navigator that is still used in shows. The entire interior was re done. The car has 19 tvs in it. It isn't that hard to build a show car if your doing it yourself and know how to. Interior isn't a giant factor. At this point I'm just going to keep the 540 classy all around. No crazy colors or anything. Just maybe a couple TVs on the head rests for the people in the back. But does someone want to tell me what their e39 m5s have on my 540? The car is still new to mods other then the speed and speakers. I took it to the next level with the engine but to be honest I didn't have to. H3uunp I think his name was was talking about how the m5 is so much greater then even a modded 540. My question is basically if interior isn't an issue to you, your changing your suspension anyways and a lot more, and you have a car that can blow an m5 all day, why get it? I'm really interested I'm hearing lala rays opinion. Because he's owned both cars and his car was very nicely modded. One of my favorites on the forum. I'm sure there's a few more but I don't know their names. But for lala ray, if your old car would have smashed on your friends m5 even if it was supercharged would you have still purchased an m5? What differences have you noticed on it?

Hey Iceman,

How is your car running? Have you sorted your issues? I read in your other thread that you had issues and had to turn down your boost to 6psi?

Did you do anything to reinforce the cylinders/pistons or is the motor still stock? Wondering because you said you were running 12psi or something.

It doesn't matter if your car has 1000hp, it still won't be an M5. Nobody loves the 540i more then myself, i love my car and i would never get rid of it, its perfect for everything i want and need in a car (minus the cup holders haha). But in all honesty the M5 is an M5, engine designed and tuned a certain way, the suspension, the drivetrain all that stuff. I mean you can replace everything on the 540i to be like an M5 or better but whats the point, just go buy an M5 or be content with your 540i.

540i is a unique beast in its own way and is one of the best cars I have driven and owned and as long as you love it thats all that counts.

^^ The E39 M5 was built in the same Dingolfing factory as the 540i and every other E39.

Well, the 540 is lighter and I guess to each his own. No m5 can stand a chance. Not stock at least. On a road test, I promise you I can take an m5. Yes I've sorted out the issues its been pretty insane. The maf issue was weird, we ended up building a shield around the front and back of it, and running one more line out of the engines crank case. The engines internals weren't completely replaced, its still an e39. However, it was taken apart completely and (improved upon). If you run boost you'll realize how weak the seals are. Those were replaced, hoses as well. Its just about finished theres just a couple things left to do. It runs great but my numbers outweigh each other. For some reason, the car makes over 500 foot pounds of torque on pretty low boost. Gearing is going to be changed to put a little more to the floor.

I completely read your post wrong, I thought it said can't BEAT an m5 lol I was wondering to myself on that one. As you can imagine, I've sunk a lot of money into this project. Its one of a kind. The m5 is cool, if I wanted one I could have easily purchased one even 2 of them with what i've put into this project. But the 540i was the beast chosen.

You could have a supercharges M5, but good work.

Heres the thing, I love the turbo. Its super cool the car drives close to a normal 540i until you give it gas. The second it down shifts it'll rip you back in your seat. Its a completely different feel having it on that specific engine has been much different then any other car I've had. I've had faster cars. But the feel of this one isn't like anything you feel from the m5 or even anything thats supercharged. It just makes more power when that boost kicks in.

So are you saying the engine was just serviced with fresh gaskets, or some of it was upgraded to better/stronger parts?
