Looks sick...... where did you find the new toy?
It is a well known car and driver on M3Forum.net. I had been looking for a solid E46 chassis with a great rollcage. This one was done by Fall Line Motosports in Chicago and is tied into the subframe connection points and the front strut towers. The chassis also has been seamwelded and reinforced in all the requisite places. Moreover, it started its life as a track car as a 2005 ZHP with 25k on the clock. All of the foregoing makes the car a perfect candidate for an S62 swap, which is what I have always wanted. Equally important, the car is nearly in arrive and drive condition, meaning I can track and even race it until the M5 is done. Then I will track and perhaps even race the M5 while the S62 swap is underway. Ultimately, having both the M5 and the M3 in raceable condition with S62s was the long-term plan. This is a big step towards that goal.

If you plan on going with the same oil system in the e46 chassis as you have on the e39, you will save yourself a lot of headache. There are couple other things one should know who is getting into this swap.

Front Subframe - you can reuse the e46 subframe, but will need to go with a dry sump

Headers - You will need custom headers. This can be done

Clutch work - the engine needs to be lowered do replace the clutch

Plus all other things that are considered when swapping engines.


Let me know when you are ready and ill get you all the contact information.

Thanks. I have been researching this swap for a couple of years and recently helped at least two others do it for their race cars. I will of course use the Dailey dry sump system. I also intend to use all of the experience and expertise I have gleaned from my Motec M190 ECU, dash and PDM installation to run a virtually identical system on the E46.

Motor mounts are my current puzzle. Any advice or guidance you have on those would be greatly appreciated. I am leaning towards asking Bob Kearns to manufacture some custom solid mounts out of 7075 aluminum.

Looks awesome Peter.

I'd be very very interested in some pics regarding the front bumper and front splitter.

Me and a mate are running an e46 330i at the moment as a track toy and want to put a front splitter on as well as making the bumper quick release. All ideas welcome, so if you have any pics, that would be great!!
Thanks, Jamie. Splitter on this car is a Fall Line Motorsports design, coupled with a Bimmerworld standoff.

I'll be more than happy to help out with what I encountered when you're ready!

Congratulations to the both of you. So, when the s62 swap is done will you and Sam be competing against one another? If so, who gets the M5?

Congrats! Looks like the racing bug truly has bitten. :rofl: Would an S62 swap not bump you out of GTS4 class? I imagine everything else is built to the GTS4 spec, it's literally a turn key for w2w racing.

I will be buried in my M5, so it will always be mine. Sam and I will share the M3, but Sam has his own M5 which, when Jed finishes his headers, will be a full blown Dinan S2 with Schrick cams (minus the differential).

True, the S62 puts the M3 into GTS5, where it will require some serious steps to make it fully competitive. But it will be. We may squeeze in a season of GTS4 WTW before the swap. Hitting VIR tomorrow and Thursday! Woohooo!

Hope you've got a cool suit for today. Heat index values here are going to be in the 100F range!

All this S62 talk reminds me of Steve Dinan talking about how much power they found within the S62 by reducing frictional and pumping losses. Wonder how much the S62 DP engines are going for these days? :3:

Two Days at VIR

Just finished two days at VIR in the new M3. Wow, what a thrill. Because it was my first time in the car at VIR, they made me start in the "Touring Lites" class, which is essentially a "lead and follow" format around the track with cars taking turns running right behind the instructor. A great diversity of cars in the group: a 2014 Porsche turbo with a sequential gearbox, a Caterham, an Aerial Atom, a C6 vette, and a smattering of others front time to time. Because I was the only fully prepped race car, I was outpacing (though certainly not out driving) the instructor himself, who was driving a GTR pace car. As a result, the instructor frequently waived me into the pits to allow everyone to pass and essentially let me run by myself. Then in my final session today, it was just my instructor and me, and man did he push me. At one point, I hit 140 on the back straight! What a rush!

I learned a tremendous amount, both about the track and how to drive. What watching videos about the track (we were running the Full Course) does not reveal is the amazing but challenging elevation changes at VIR. They are dramatic, but oh so fun. I also continue to need to be smoother with my heel and toe downshift, which tend to fuse into one jerky movement and every now and then with not enough clutch and hence, a missed shift. That is really my focus area. My lines and speed apparently are good, but dealing with multiple quick heel and toe downshifts followed by sharp turns, well, that is not exactly where I shine. A goal for next time.

Anyway, here is a pic and a video shot by my lovely trooper of a wife, who braved the heat with me the past two days. Onward and upward!

PS: Couldn't get the video to work.

I have a tough time with that too, especially off the back straight and into the rollercoaster. And its SO hard to practice it on the street between track days, because, frankly, if you're braking THAT hard/late on the street going into a turn, you're doing it wrong.

Was that your first time at VIR, or just first time in the M3?

First time other than an HPDE guest lap at VIR. First time in the M3. So my first serious experience there.

My instructor gave me the critical tip for handling rollercoaster: downshift from 5 to 4 in the initial braking zone before the first turn, then downshift from 4 to 3 the moment the car goes straight after the first turn. It's like a miniature straight before the elevation drops, and that is where to downshift while trailbraking. Once I started doing that, rollercoaster became my favorite corner, followed by hogpen and the front straight.

My real bugaboo is the two apex corner of oaktree. I lose SO much speed there, I yelled obscenities every time I went past. The pit guys said they heard me!

I hear you. Everyone says to practice heel and toe on the street, but the braking is nowhere near as hard on the street, so it's not the same. Gotta master it with more and more seat time.

What a hoot!!

I'm guessing your gonna lose that stick with the S62 swap to pick up those extra couple of seconds?

Peter,

Do you have a trick iRacing setup at home yet? :)

Speaking of donteverlift Hogpen, I've never liked that portion of VIR, but perhaps it's a bit better now that the track has been repaved and all.

Heel toeing is one thing I am a complete noob at and have not got the hang of yet. It was the reason we ended up ruining an engine mount which in turn burst the header tank on the radiator at the 'ring this year.




Any tips?

Maybe, but I think it is more likely that I will find a way to mount a ZF five speed to the S62. Those things are light, bullet proof, and you can upgrade the internals. Plus I just love to shift.

Not yet, Chuck, but it is definitely in the cards for next year. Though I DO have a 50th birthday coming up!

Interesting about Hogpen. I find that nipping the inside rumble strip as you sweep into the straight keeps you fast, on the track and leaves you at exit on the far left side of the front straight where you want to be. But I did notice my instructor in a street car on street tires having to be careful right there. I would always catch up to him right at that point and then be on his *** on the entire front straight.
