DieSekte's S54 swap

[diesekte]

Thank you...couldn't have gotten it running without all your help. Appreciate you letting me ask 5000 questions lol

Good job man! all that hard work pays off eh? The power and sound of the s54 is very addicting :)

I don't think it's necessary to change it that much, personally I'd do it once at 100 miles and then do a regular oil change interval after that.

I'm still breaking in the clutch as well so I haven't been above 4k.
I went 30 miles on first change. Plan for 500 on second, then 500 again, then will switch to synthetic

30 miles??
Damn, now you have me concerned.
I've done around 75 miles so far.
Was going to do a couple hundred before an oil change.

uhm, the M3 came with a 3.64. lots of people with E46s upgrade to 4.10s.. I'm sure it's fine, it's not like it's an N54 or an eta that has the powerband of a diesel.

Uhm, their tires are also 2" taller than e30's tires. :)
That makes a huge difference.
My 3,46 in an e30 is equivalent to a 4,10 in a m3

3,73 must be ridiculous.
I have a 3,46 in mine and I feel like 1st gear is almost useless.

Oops yes I meant csb...original post edited, thanks
Yeah the 3.73 makes 1st pretty much unnecessary

Haha yeah.
6 speed e30's are hella fun.
Still being gentle with mine until I break in the clutch and rod bearings.

How many miles are you going g on the the first oil change?

Our builds are almost identical, except you spend a lot more rebuilding your engine than I did. Haha.

You mean you used an e30 center support bearing, not guibo.

I figured out a lot of the stuff you mentioned.
Nice write up.

3.73 LSD, modified with 3 clutches

[Sirrrrred]

What diff are you using

[diesekte]

Dave, I ended up having a shop in dallas for it. I wanted to be able to physically appear at the shop if there was an issue or I needed to retune

I mostly didn't change them because I was over budget at that point and the ones I wanted would've been another 1k

[superleggeram3]

Any particular reason why you didnt change the rods while you were at it ?
