[SOLD] M52TUB28 alloy-block 48k miles

[samurai7]

pull the head, add timeserts, swap a single vanos head on and we can start a club of badass lightweight 24v motors

Just curious: why?

[GG///M3]

I'm semi interested . How much without the dual vanos head?

bump. Had two interested buyers this week who flaked on me.

Come on people, this is a good deal!

In the US, the M52B28 used an iron block (except for the M52B28 in the Z3 which was an aluminum block), while the M52TU used an aluminium cylinder block. The US M52TU had cast iron cylinder liners in the aluminum block.

Really? could swear I've seen motor weight breakdowns that list m52tu iron and m52tu alloy...

I can't find any evidence of an m52tu iron block being made. I have been looking into it a bit because I would like to turbo my z3.

Every m52tu was alloy, so any e46 328 or e39 528 would have this same engine. It's really more like an m54 than an m52(single vanos).
I believe m54 and m52tu cyl head and maybe engine block have the same part numbers.
So swapping would be more like an m54 swap, at least as oil pan mods are concerned. This engine does have a cable driven throttle though.

Than being said, it is a nice smooth motor, my z3 2.8 seems to have about as much power as my s52 e30, at least until 4000 rpm.

Bump was *this* close to selling it a couple days ago but the buyer backed out. Still FS

bump. Everyone that wants this motor lives too far away... :/

This came out of a 98 or 99 z3. these were the years before they moved to the m54.

I don't know if the m52tu in an early e46 would have the alloy block or not, but there is a possibility it would have the heavier iron block.

As far as I know only late production z3s had the alloy block m52tus.
