As asked here is a small list of parts that you could change up to if desired for added performance:

CP Different C/R's : $1049USD - http://store.vacmotorsports.com/cp-p...kit-p2030.aspx

Since I'm waiting for parts I will start on the different mods that are required for the OBD I swap:

OBD I Single Vanos Wire Harness
OBD I Sensors- Cam position sensor, crank position sensor(front of timing cover), Vanos solenoid(can use OBD II solenoid but the harness must be extended), Air intake sensor, Idle control valve (can use OBD II as well), OBD I MAF or HFM.
OBD I or II Ignition Coils - you have to modify the top of the valve cover to allow the coil wires to pass through nicely.
Silver Label 413 DME(EWS) or Red Label 413 DME(non-EWS)
M50 Manifold with throttle body and throttle position sensor.
--Feel free to add anything if you don't see it here.
21.5lb injectors (if you don't have an M3 or 328)

Chip required to run S52 OBD I system:
Red Label 413
TRM - $250 - http://www.racersmarket.net/index.ph...mart&Itemid=93
Turner - $250 - http://www.turnermotorsport.com/p-13...injectors.aspx

For the Silver Label 413 DME you need to buy the Turner chip with the EWS delete.

Upgraded Parts For Swap
--24lb injectors (if you have upgraded cams)
--540 HFM
--Chip to sustain 2 above mods(Turner or TRM Chip can both be custom set)

Or talk to Barrie from Midnight Tuning (PM bmwconnect)! He'll set you up nicely with a custom tune.

Nice build thread. Good job man

[egye30]

Ive got a good 413 red label if you still need one

[matty.dc]

Ive got both a red label and a silver label

[matty.dc]

Today, I bagged and labelled all of the hardware since the block has to be bare bones to go for the bore.

Contents of bags
-Main Bearings, bolts, oil squirter and caps (labelled #1-#7)
-Front timing cover harware
-Oil Pump bolts
-Oil pan and baffle bolts
-Rear main seal housing hardware
-Additional hardware (hoarded from the junk yard)

-When removing the top of the main bearings (block side), make sure to note the direction of the tabs (picture 1) and also make sure that the piston oil squirters don't fall out(picture 4).

-Pictures 2 and 3 are just pictures to remind me at the end of the build where all of the different sized bolts go.

Hey I saw on the cruise thread you were wanting to break in the motor before the spring cruise -- hows the project coming?

Well here you go! The motor is in and now has about 200km on it. With the engine covers, I wanted a little bit of a different look so I did them graphite (same colour as my wheels).

Noob question:

When rebuilding, do you always need to swap to new, larger, pistons?

Can't you just replace bearings, seals, etc?

[kruler]

Did this build thread go from bagging parts to having the motor in and painting engine covers?

Not always. It's really dependant on the wear in the cylinder. In my case it was quite severe so I went as big as I could.
