When you were looking for your motor, what did you check for besides mileage? What are some tips in finding a good used motor? Check for leaks etc...?

it'll fit no problem, but the swap is going to be a lot tougher than an M52/M54 swap

There was a guy on here a while back who made a s54 work in a 323. Can it be done? Yes but look at what all he had to do

ToddInLou - Its guys like you that make me want to post this info. You need NO electronics from the 330 thats right NONE. Even a BMW tech told me im going to have to flash my DME and all kinda crap. I didnt do any of that. They are the same motor I had no plugs left over or anything. But like I said more details to come tomorrow...


-Ray

it has been tomorow for a long time . tell us a bit more, i have a m54 3.0 in my garage with 30000km's. this is verry intresting and i woud like to do this swap. you did not flasch other software on your dme or anything?

Hey guys sorry it took so long. Working on the car last week put me behind and I just didn't get a chance to come on here.

The main thing here when you use a 323 as your base you switch the intake manifolds around. So the 323 goes on the 330, and that's the main part other then that its a straight swap. Only hard part i ran into was the SAC(Self adjusting clutch) as I had never dealt with one before. But with the right tools its easy to swap it around. All of the sensors are the same everything plugs right back into place. If you do that right you shouldn't have any check engine lights either. Only problem I ran into now is vacuum leaks. That is due to the brittle plastic lines that they use. I was swapping the motor at 2 in the morning so I didn't have access to the nearest parts place to replace them all. Over all though its well worth the swap as its quite easy. I guess i should right a better DIY for the DIY section but that will come in time! Anymore questions feel free to ask!


Anyways here is a bunch of crappy pics...at the time I wasn't to worried about taking them more at getting my car back on the road!

Here are some more pics...as you can see the check engine light is on...because i have the MAF disconnected. This is because im getting random misfires...due to bad vacuum lines... but if you clear it on idle its fine...i gotta fix it but im lazy also i threw in some springs a cone and the 330 exhaust while i was workin on the car...ps and yes i need to wash my car

thanks djnekkon!
The extra hp over the stock 170hp M52b25 is well worth it when you throw in a m54b30 which has 228hp!
even more when i spent less then 750cnd on it!

Thanks bro...hmm taking the motor out of mine the first time 6 hours...the 330 was 4 hours and putting in mine was probably 10 hours as i was getting tired by 4-5 in the morning...so progress was moving slowly lol

Thanks again...
yeah well i had to drop the motor my self otherwise he wanted 1100 or something plus i dropped the diff for him...i found quite a few m52's in that range locally but only one 330..hence why i grabbed it...

Id do a compression test...also check the oil...and mainly find out why the motor is out of the car/coming out crashed cars are usually your best bet. if they didn't roll no damage really will be done to them...

Hmm very interesting. Good job! I wonder what a GT1 would think of this swap? Now you are really making wish I had picked up a 323i that was real cheap and local.

***edit*** Let us know if you have a chance to put it on a dyno. I'm wondering something about the DME tune on these cars. If you read up on it the 323 and 325 have a pretty conservative DME tuning to them this is why you get more power out of the Shark Injector. Maybee the DME is preloaded with all 3 maps or maybee you could gain performance by flashing to the more aggressive factory DME settings. I'm just hoping you see the full advantage of the swap. I'm sure some wizard of smart can chime in on this one.

This is a good. If my car's engine gives up on me, then I have an option which provides more performance that isn't much more expensive than just swapping with the same type of engine. Good job. I'm looking forward to reading the full DIY sometime. Thanks for sharing your experience.

the wireing is for when you use the 330 intake manifold, throttle body and maf, which are all significantly larger

what intake manifold did you use??

The Intake is NOT significantly bigger...putting them beside each other you couldn't tell which is which...But yes the different plugs are for the electronic throttle control...and the intake boots are almost identical its the end part which attaches to the MAF which is larger then the m52tu25 MAF...but i just put the m54b30 intake on the m52tu25 throttle body!
