For the S38B36, the displacement was increased to 3,535 cc (216 cu in).[5] This was achieved by increasing the stroke by 2 mm (0.1 in) to 86 mm (3.4 in),
S38B36 3,535 cc (215.7 cu in) 232 kW (311 bhp)
@ 6900 rpm 360 N⋅m (266 lb⋅ft)

what a joke
literally now one of the fastest coupes on the road
for me, its not about having one of the fastest coupe ... if i want to go fast on any kind of road i will get in the 911 ... for me a coupe is about style, beauty and the love of an open road with hills + sweeping turns. too much speed / power can be a lot of stress for the old coupe suspension + brake technology ... not to mention 45+ year old body ... with or without rust. but that's just me ... YMMV.

I'm with you Scott! I saw a 04 911 4S 6 speed manual that would be fun to have here in Reno on icy road days like today :)
PS any chance we can have a chart spelling out what YMMV and many others mean for us Old Dudes?

Your Mileage May Vary. not sure what you consider old ... i'm about to hit 61, so i don't consider that to be young.

S38s are awesome! But it seems less hassle to just turbocharge an M30 to get 300+HP? Of course, one would need new pistons, but if needing a rebuild anyways...

Of course, I'd use the banana intake instead of a tarantula:

I have owned an S38B36 and an S38B38 M5 and would give my right arm to get one of these engines into my E9. Preferably the B36 as I felt it drove better and I believe are stronger.

Unless you have a matching numbers car which you're going to keep in cotton wool and take to concours shows, then anything goes. When restomodding mine the only caveat I had is that the parts must be BMW (or Alpina).

this is very similar to previous discussions on the e30 m3 board ... putting a s52 into an e30 m3 in lieu of the wonderful s14. the value of the e30 with the s14 (original or replacement) is so much more than one with a s52. the thing about putting a 5 speed into a coupe, nobody can tell from a general look. the s38 is certainly a cool engine, but it looks out of place with the individual throttle bodies and the plastic bits on a coupe. just my opinion ...

That’s true, I fully agree on the e30 M3.
But shouldn’t the comparison be made by putting a S52 in an e30 318/320/325i instead, since we aren’t discussing e9 CSL motor swaps.
I think 99,8% agrees that swapping engines in a CSL would be a bad idea.

Agreed, that swap would not be on my list although my 74 2002 with the S14 swap is the bomb. My 2800 has value as a nicely restored car and I dont think that a VERY well done S38 swap will hurt it. My S38 doesn't have all the plastic on it with exception of the spark plug wires which I kind of appreciate keeping the top side clean looking. I look at the ITBs as just the next generation of the side draft Webers, but without the finickiness(wd?)
