I'm about to order a few hundred dollars worth of maintenance parts, have questions..

[Joey Link]

Here's my list so far:

Valve Cover Seal
Valve Cover Paint
Exhaust Stud
Exhaust Gaskets (Manifold to Collector)
Thermostat
Water Pump
Camshaft Seal & O-Ring
Coolant Hoses
Throttle Body Heater Gasket
Coolant
Timing Belt & Tensioner
Engine Oil & Filter
LSD Oil
Fuel Filter
Flex Disc
Flex Disc Nuts
Rear Transmission Seals
Transmission Oil
Center Support Bearing
Rubber Shift Lever Gasket
Shift Linkage Refreshment Parts (SSK?)
UUC Delrin Bushings
Antenna Grommet

That should cover the engine and transmission, as well as a few other little things.

My first question, how much do you guys think this is going to cost me for all these things?

Second, for things like the thermostat, water pump, and other parts that have multiple manufacturers, is there one brand that's better than the others or are they all the same?

Third, where's the best place to order from? Discount Import Parts is close and I could get the parts right away, but their prices are a little bit higher (only around 10% I'd say). The other nice thing is I could return them easily. The downside is I won't be able to select the manufacturer of the parts, if that matters, since they don't carry multiple brands of the same part.

Fourth, while I'm doing all this is there anything I'm forgetting that I should do?

Thanks guys.

Just talk to Patrick at BMA Parts. He'll hook you up with everything you need.
With a long list of parts like that, I'd recommend emailing him instead of calling though.

I was headed up to PDX a couple of weeks ago. Similar list, too.

I ordered from BMA while on the road, since every price I checked was about 15% cheaper.

[Joey Link]

Nice Luke. Sounds like BMA it is. Anyone have an answer to the other questions? Especially #2, there's like 4 different brands of water pumps. And what thermostat temperature is better for the Northwest?

[87-325ic]

get like an 80 degree C t-stat, better heater operation, lets the car warm up faster.


and i only use patrick too, he is also good at reccomending brands..

call and talk to him,

[StereoInstaller1]

What is your plan on the SSK? I just did the Z3 dealy-o and am unhappy because I half-assed it. I only did the shifter and pivot. It is still better than it was, but it eats dick IMO. PLUS the shifter is forward from where it is supposed to be, because it is straight (unlike its dick-eating linkage).

So, UUC, AKG, OE, whoever, get the whole package, be prepared to drop whatever parts necessary to replace ALL of the parts...or don't bother.

I wanna try the "raised cup" deal too. I hate the extreme notchiness.

Go with the Z4 2.5i shifter.

Then get new yellow spacers, get a new shifter knuckle, replace the uuc delrin bushings, The way you do everything right the first time.

Coolant Hoses
Buy BMW branded hoses for the large diameters -- aftermarket hoses are not
molded with sharp-enough turns and will rub on the fan or pulleys!

Throttle Body Heater Gasket
About $1.20, at the dealer only

Coolant
Unlike a few years ago, you can now easily get good aftermarket coolant.
Make certain it says "Global Lifetime" or "Global Extended Life". I use
Peak but other major brands have specific products that work well.
Timing Belt & Tensioner
Contitech only, and buy the kit! About $25

Interal relief: minimum diameter of 14mm to 45mm deep
ST Tools BMW3025 socket is 39.04mm OD, 16mm deep flats, 66mm deep

Center Support Bearing
Rubber Shift Lever Gasket
Not the shift boot, but the rubber bellows? Boneyard part.
Unplug reverse wires from the transmission side to feed through.
Shift Linkage Refreshment Parts (SSK?)
This depends on which linkage you have. Look before buying. I have
some extra parts because I trusted someone elses list the first time.
UUC Delrin Bushings
Perhaps replace sloppy parts w/ OEM before deciding that you need this
25-11-1-220-832, Shift arm to transmission bearing sleeve 26mm, 8.00/6.80
Superceded by 25-11-7-519-669
Antenna Grommet

Fourth, while I'm doing all this is there anything I'm forgetting that I should do?

yeah, ask yourself "why am i spending all this money on a stock m20, when a m50 is another few hundred away?"

[Jand3rson]

You 24V guys all think alike. I swear, you're like Zombies. :D

If you installed it the opposite way, it would be in the middle :). That's what my friend did for me.

weve all seen the light! and harnessed the POWER:hitler:!!! lmao

[bddog]

I always buy the thermostat that stays open, as opposed to closed, when it fails.- Steve

Wow, thanks for taking the time to post all that. It helped :)

How much did your swap cost?
