E46 M3 S65 swap updates

[e92Mjunky]

hey guys, few updates since I have put 4,000 miles on the swap
CSL boot lid on the way
trying out Ground Control Bump steer adjustable tie rods to offset the angle/geometry of the lower rack, should help with some tramline issues i have had
exhaust is being upgraded to 2.5" and will be retuned, hoping for 390-400 wheel
back in August put a carbon fiber intake system made here in Austin, lowered IAT by 30 celsius
rear diff R&P changed out for 3:85's out of a low miles E9x M3
cant think of much else, here are some pics of her recently

thanks man, will be once the final tuning and CSL deck lid is installed, really is a fun car to drive

[Scrippy]

So cool! I love the E46 & E92 so an E46 with the S65 is freging awesome IMO!

[roastbeef]

this is cool as hell. looks factory. its like a factory m3 gtr.... but with a s65. how is the balance? if i remember correctly, this motor weighs slightly less than the I6, but how is it with all the other crap in there it needs to function?

So awesome. Got any vids?

yes weighs less, but the 6 speed out of the E9x weighs more than E46 M3 6 speed because it has an trans cooler system which was retained. So it is a wash. The engine sits low and back, balance is not effected, few issues with added steering links to get around the bank 2/driver side header, but found some things that will help

thats badass. how does the dash look? did you swap over the tach or is it all franken3?

I hate to be that guy that brings this up - but whats something like this cost to replicate? I can't imagine its cheap but holy hell is it awesome! I'd love me a s65 powered e46 M3.

Whats the ECU setup like?

I've had the good fortune of taking a ride in this car and it's a hoot!! Raw power and very well balanced. Even though is as close to perfection as it gets I know the owner will continue tweaking this beast to no end, well done indeed!

[buddalun]

Epic. Great work e92Mjunky

Motec M150, car, drivetrain, Motec, basic stuff to get car running/tuned all in about $50K other mods, like CSL roof, coil overs etc..that is extra of course. Cheaper than a new M2..

fine tuning man, hoping it picks up another 20hp with opening the exhaust up more

The s65 short block (no heads, cams, vanos, etc) is lighter than the s54 short block.

The s65 long block (complete engine-- includes heads/cams/vanos/etc) is ~30 lbs heavier than the s54 long block. You can verify this on realoem or any number of people who have weighted both engines, fully dressed.

It was a very tricky (to put is nicely) word manipulation by BMW, claiming the s65 V8 was lighter than the s54 I6 :P

That said, being 2 cylinders shorter, I wouldn't expect the weight distribution to be meaningfully changed.

I figured there was some trickery with the words... makes sense.

Nice build!!! This is definitely a sleeper e46.

I still think that's very impressive: a larger, higher displacement engine with more sophisticated valvetrain + components is only 30 pounds heavier than the one it replaces.

It is, but a large part of that is also that a V block is inherently a more compact form than an inline block.

That, and the S54 block being made of iron
