HPF Turbo Odometers - What is the Highest Mileage HPF Turbo M3?

[HPF Chris]

We get the question "I have a high mileage M3... Is it safe to turbocharge my car?" a lot, so I thought I would share some information about our experiences with turbocharging higher mileage M3's. The M3's we've turbocharged have ranged in mileage from 9,400 miles to 102,484 miles. It is likely that there are HPF M3's outside of this range because many of our turbo kits are being installed by shops, customers, and the ones shown below are just a sampling of all of the cars we've done.

There have been "No" differences in power output, reliability or driveability on any of the higher mileage M3's as opposed to the lower mileage M3's. What we have found is that the higher mileage M3's are more likely to need a new battery, new starter, and some of the bolts are harder to get off. The 2001's require a little more attention installing the intercooler because the front bumper is different. Those that have switched to a single pipe mid-pipe will lose about 20rwhp on our turbo kits. Those that have switched to several different exhaust systems will also lose power depending on the exhaust system they bought. There are a few exhaust systems that will increase power and I can talk about that on another thread. Typically when the car doesn't make the power, we put back in the factory midpipe and factory exhaust and the power returns to the same level as we advertise (typically 600rwhp on race and 620rwhp on race+meth)

As far as long term reliability and engines, it is important that everyone changes their oil and oil filters regularly and uses the correct 60W oil. This doesn't change whether your car is brand new or has over 100,000 miles on it. If your car runs good now (without a turbo), and the compression is even across all cylinders, then there shouldn't be any problems running forced induction no matter how many miles are on your vehicle.

If your car does have a cylinder or two that is low on compression, you can send it here anyway. It is relatively inexpensive for us to rebuild your motor and we can install the turbo kit while it is here. Just coordinate that with us prior to shipping your vehicle.

Here are some odometers from a sampling of M3's we've put turbo's on ranging from 9,400 to 102,484 miles.

you've made my day Chris :excited:

Only M3 I could afford (without withdrawing $$$ from my HPF Stage 2 account) has a little over 60k miles. Good to hear the power output should be similar to, one with lower mileage.

Good info Chris...

I was wondering the same thing for awhile now. Good to know the S54 can withstand F/I after a few laps around the globe.

btw I love you guys, HPF :bow:
My hpf slush fund is growing...see ya at B-fest

Very nice Chris.

Could you make a new thread talking about your experience with various aftermarket midpipes and exhausts installed. I would like to know which showed improvement over stock and which didn't.

Hey Chris, you guys noticed the motors start to pressurise the sump a bit with boost after a while and push oil out the rocker cover breather. Couple of them here in Oz are doing that on 10psi (one turboed 75,000miles one blown 20,000miles). Definately having to run catch cans and return them to the sumps so the motors not sucking it back in.

None of ours have had that issue, but we let the turbo scavenge the excess crank case pressure through the PCV that is already there.

Yes, I will at some point.

Absolutely. See you there.

Yeah that's how these are set up. Just seems to be pushing oil out as well so your sucking oil back into the intake.

Would be interesting to see if you get one back for a service that has had it on for a bit (not a built motor of course) and see if all the inlet plumbing has oil in it.

I can't remember the correct figures to work it out but 11.5:1 comp with 10psi boost would be up around 15-16:1 comp when your on it. So it's no suprise it's pressurising the sump a bit under boost. Just something we have found anyway.

i wish i could afford something crazy like this

No oil in the intake on any of the M3's we've done. You may be running into turbo failure issues. Turbo failures will often send oil into the intake and exhaust. Good luck.

Nope that's not it. Remember one is an AA blower and it's doing it as well. Both are only doing it on boost, not cruising. The turbo one has a catch can and you can see it only does it on boost, not cruising. So it's definately pressurising the sumps on boost.

Maybe us Aussies just drive harder than you guys ;)

Will be interesting to see how they all go on stock motors anyway. But I guess it depends on how often people are running the higher boost as well. We are running 10psi all day everyday on pump due to our fuel being a lot better.

We have 20 customers running on these kits in all different climates and all different parts of the world. All of them except for 2 are running on stock motors up to 13psi. The other two are running 23psi. None of them have the crank-case pressurization issues that you're talking about. I'm sure you are just joking about Aussies driving their forced induced M3's harder than the Canadian and US drivers. Even if it were true, it would have very little to do with the crankcase pressurization you are experiencing at 10psi.

Let's talk about the crankcase pressurization issues you're having on another thread as it's unrelated to our turbo systems. I would be more than happy to help you over there.

Chris.

[m3 lover]

hey chris was wondering is stage 3 the last stage on will there be a stage 4

[nolocontendere]

Which exhausts make more power? How is the magnaflow?

[HPF Chris]

Yes, stage 4 is already in the works. We're going to run a triple disk clutch and a slightly larger turbo (76GTS). :)

I don't believe we've done a car yet with the magnaflow, so I can't be certain.

Yeah dude I was just crackin jokes:thumbsup:

[Disco_Monkey]

You mentioned a loss of power with aftermarket midpipes but I thought that section 2 X-pipes (single larger non-resonated pipe) flows much better than the stock H-pipes (dual pipe with resonator) . How come the car makes more power with a stock H-pipe rather than a single larger X-pipe?

What if one were to have an electronically controlled dump valve in the single X-pipe to bypass the muffler in race fuel mode?

This is very interesting. Can you elaborate please?
