M-Tech ti undergoing S52 swap! 332ti in the making!

[318teeeye]

I dropped my car off today with Marc (Mdpowered) at MoonLite MotorWerks In Gilbertsville Pa to start the S52 swap process. There will be pictures of the swap as soon as he starts. While I was there, my eyes could not stop wondering to look at all of the nice rides in the making there at his shop. I can hardly wait to see the outcome!

I am also doing a M50 intake swap onto this motor once I get the feeling of the balls the surgery has given it. I am sure I will be happy with the enlarged testicular sack this car will have in the end!

Do the intake before the engine is installed....

Pics asap!

Here is my M50/S52 "Project 332ti" as it sits now.

hey how much are you going to pay for the swap? Is $5000 too much for a swap?

That price sounds just about right. The motor, trans, wiring harness, ECU, install, 6cyl. cluster and key alignment is around $4,000. Then you have to figure in the cost of a rear to be fabricated. So around $5,000 sounds about right.

The ti rear is not strong enough to handle the added ponies for a prolonged period of time. The rear has to be taken from a M series 6cyl. or whatever else you want depending on the gear ratio, then the shafts have to be split so you can take the inner from the "upgraded" rear and outter from your ti. If you just leave the stock ti rear in it will not hold up to much abuse and fail sooner than later.

yes and no...

Yes the differential will need to be replaced with a medium case diff. The stock ti diff is a small case and will not hold up long to the added torque of the 6cyl swap. No you can't use a differential off any M series or 6cyl. e36 diffs WILL NOT FIT ON THE TI. They have a completely different mounting setup. The Ti uses the same mounting points and diff hanger as e30's and Z3's. e24's and e28's have the same mounting points, however the diff hangers are a different style. If you use an e24 or e28 diff, you'll need a cover off of a 6cyl e30 diff or a 6cyl z3, MZ3 or Mcoupe(not an M3 2dr, but a MZ3 Hardtop). 4cyl BMW's came with small case diffs, 6cyl BMW's came with medium case diffs and 8cyl+ came with large case diffs. You can use a diff out of a 6cyl e30, 6cyl Z3, 6cyl Mcoupe(NOT an M3), e24 or e28. Again, if you use an e24 or e28 diff, you'll need to swap the cover and output flanges.

As for the halfshafts, no you don't "split" the ti shafts or anything of the sort. The ti shafts are too long since the medium case diff is wider than the stock small case diffs, the halfshafts won't fit right between the wheel hubs and the differential output flanges. Use 6cyl e30 or 6cyl Z3 halfshafts since they're shorter and are designed to work with the medium case diffs. The differential output flanges will have to match whatever halfshafts you get. The flanges pop right out of the sides of the diff, with a big ass screwdriver or prybar.

Ok, thanks for the info. I was not sure what had to be done as I new to this.

[318_mzk2]

that doesn't require any fabrication tho....maybe just swap diffs and axels..
i got a friend that has a fully built s50 pushing a lil less than 400hp..and has a complete mcoupe rear to hold..

Yeah, there is a lot of swap info on this site. The only fabrication I can think of is the exhaust and making little spacers for the rear abs sensors if you swap in a medium case diff and E30 axles. Jesse made some beautiful spacers but I think you could also just stick a washer in there.

I also think the stock small case rear end is more stout than people give it credit for. Now, if you are going for big power, that's a different story.

+1, i beat the living snot out of my small case before it died. It had around 202k of autox, track, and drifting on top of my 2.5, track, drift, hard launches.
