if i recall correctly the biggest diplacement you can go with the m52 aluminum is 3.1. I don't think you can bore it out because the block is sleaved with something. If you are going to boost the engine i think you'd want to use the 2.9 variation. not 100 percent on this but i am pretty sure.

hummm.... ill have to look into this.... if that engine could indeed go bigger that would make me very happy..... i also wonder if you could indeed put the TU head on it

and yes the m52tu had double vanos and was in the 5-series

[SpencerM3]

Ah, 5 series.

For some reason, I always associate the M50/52's with 3 series, which I think only had single vanos.

[DrMcDave]

what does the tu designation mean, i am not familiar with it.

What are the benefits/drawbacks of double vanos vs. a regular vanos engine.

uhh...well with the E46 ('99) came the dual vanos engine 2.8 in the 3 series. I am not sure who is saying otherwise.

Thats an M54.

E36's had the M50/M52.

the 99 e46 had the m52tu, I believe the tu signifies a change in the VANOS system.

DIdn't see it mentioned, but the new Euro Tuner has a RMS Supercharged 3.3L in it. 454 hp, 389ft-lbs @ the wheels

yes, 99-00 e46's had M52TU (Technical Update) engines, 2001-04 are the M54's, and whenever the e90 comes out it will have a new I-6 dubbed the R6 for now.

[kylebes1]

In the Z3 they used 2 different aluminum block 2.8L motors in '99. They had the M52 and M52TU. I bought a disassembled engine thinking it was an M52, but ended up being an M52TU. I believe they switched with the Z3 around September of that year. Tricky bastards.

On that note, if anyone needs any M52TU parts, I'm your man. :)
