I have decided to go a different route then most and install two indivual throttle bodies (ITBs) instead of a single throttle body and plenum type system. So far everything is working great based on Speed Density (Maifold pressure reading) which many thought would not be possible. I also have a more agressive cam with no overlap which probably makes the situation easier (278 duration, .288" lift). More information to come as I install EDIS spark control. Until then

Differential Types - 2002 and 320i:
Early 1600's and 2002's came with a long neck differential. These were phased out in early 1969. They were either 4.11:1 (1600) or 3.64:1 (2002). They are very rugged (heavy) and easy to come by, but not rebuildable due to the lack of available replacement parts. If you want to switch to the later short-neck differential, you must replace the entire subframe and rear suspension. This sounds tough but is actually fairly e

Mike taught me a way to bleed the clutch system on a five speed that makes things pretty simple.
Get a pump type oil can from your local hardware,dedicate it to brake fluid. Put a section of tubing on it that fits the spout on the oil can and the bleeder screw.
Fill the can with your favorite brake fluid, connect the tubing to the bleeder screw, crack the bleeder screw open and start pumping.
Have an assistant watch your reservoir to let you know when the reser

How to perform a compression test?
ALUMINUM HEADS? loosen the spark plugs when cold, and snug up to warm up the motor
remove all the plugs
battery must be fully charged and starter motor spinning like mad
disconnect your ignition primary - even more important if you have a HugeBox-o-Transistor mega-spark system
also for all of you with powered fuel pumps and injection systems - de-power yer pumps so the possibility of FIRE is eliminated!!
hold the throttle

Introduction:
This conversion is not recommended for anyone who is not mechanically knowledgeable and ready for a challenge. There are many steps involved and several places where fabrication skills will be required. If you feel that you are not ready for this, it would be best to leave the conversion to a professional.
When considering this conversion, it is advisable to do signi
Tools:
Small Hacksaw (Junior Hacksaw @ Homedepot)
Hammer
Large flat-tip screwdriver or Chisel
Overall this took me about 10 minutes once I finally got started. First remove the blade from the hacksaw and push it through the open section at the bottom of one of the hanger bushings. If you can not get it through on its own, a sharp knife should help. Next reassemble the hacksaw with the blade through the bushing. Now use the hacksaw to make some room by cutting the bottom nub of the bushing ou
I've seen several mentions of plans to use the 320i inner cv joints when installing a limited slip diff from a 320is but didn't find any posts about how it went. Most were aiming to avoid both using spacers and redrilling the diff output flanges. I was only concerned about avoiding the latter. I decided to take a few photos along the way to document what I found. There are lots of articles about other aspects of the swap so I'm just focusing on the dimensions of the axles below to supplement wha
The majority of ‘02’s retain their original factory engines. Each car’s original factory engine was stamped with an engine number that matched that car’s VIN. More specifically, the engine’s block was stamped with this engine number or VIN. Thus, even when the VIN and engine number match, you still might want to do some sleuthing to see, for instance, if the engine’s head might be original to the car. One cannot simply assume that an original block will be accompanied by an original head.
This has taken me a full DECADE of trial-and-error-and-refinement but I have FINALLY cracked this awful nut: how to properly make a good throttle linkage for an EFI conversion! Note that you'll still need to tailor this to your particular manifold/throttle body/mounting points/etc., but I PROMISE this will get you 90% of the way there no matter what setup you are running and I also GUARANTEE that's it's better than what you've already managed to cobble together! So let's get started! As always

Using this Google spreadsheet developed by Grice Mulligan, AKA williamggruff, users and abusers alike can investigate the outcomes of matching various BMW transmissions and differentials, and calculate a variety of RPM and speed values that result.
Inputs are simple: Tire circumference and Redline RPM. Tire circumference can be estimated using the link provided. Redline RPM can be a target RPM, such as a preferred RPM at a cruising speed.

Need to store or transport an M10? Need a way to support it on its side properly? Here you go. I spent a little time today putting together a wood stand that supports and M10 laying on its exhaust side. Then mounted it to a board with tiedowns that lays in the back of a pickup bed.
What you need:
Some 2x3 stud
Some 2x4 stud
3in drywall screws
Saw
Drill
Start with the studs and build this. All the measurements are in the pictures!
note the notches in the 2x4.
It fits against the engi

Tools and parts you will need:
High-lift jack
Medium- to high-lift jack stands
2 wheel chocks
10mm, 13mm socket and box wrench, extension, ratchet, and a swivel makes life easier but is not required.
WD-40 or similar
razorblade (to scrape old gasket)
NEW paper oilpan gasket and ultra grey sealent (Paper gaskets wont seep like the cork ones do). They are available at any independent shop but will have to be orderd. I can get them if you can't.

for those with M2's or E30 M3's. step by step on doing valve lash adjustment.
I will skip the obvious that you have to pull the plug wires, valve cover and spark plugs off..
First you need tools.
Feeler gauges, micrometer, bmw valve bucket depressor tool, magnet-on-a-stick, small pick, air pressure source and bicycle pump nozzle, light, paper/pen and magnifying glass.
For each set of valves..
Rotate engine so that the lobes are pointing away from the valve shims

Had not seen full “how to” for diff swap, so here you go.
Simple job. Well, simple on a car that gets its diff swapped a lot. No promises on a diff that has been in a car for 40 years…
What you need:
A diff
Two 17mm combo wrenches
17mm socket
19mm combo wrench
19mm socket
17mm socket
6mm hex socket (for 2002 cv joints)
8mm hex socket (if you have 320 cv joints)
Jack stands

First, get the car up on jackstands.
Remove muffler
Lock e-brake and put car in gear
Loosen the 4 nut
My son and I completed the installation of an electric fan in our 1970 Chamonix 2002. As with most things with this car, it wasn’t particularly difficult. It did require a little research (on this site), access to a couple of wiring diagrams, a small pile of parts,and a modest level of problem solving skills.
There is an excellent “how to” article by Zenon Holz at this link http://www.zeebuck.com/bimmers/bmvseite/)and a great wiring diagram from Shaun and Zenon at this one: Electric Fan Wiring

Installing Exhaust Manifold or Header Studs
By John Aho
Studs are designed to be fitted only "finger-tight" into their threaded hole in a casting. However, a locking type of nut (PTN, or prevailing torque nut) is often specified to go on the stud. These two facts present an inherent dilemma. The grip of the PTN on the stud can easily turn the stud when you don't want it to (how often have you removed an exhaust manifold nut and
Where do i get the kit
The Warm-Up Regulator kit is now available for pre-order at the 2002 FAQ Store. We expect the new batch to be shipped later this summer
What is a Warm Up Regulator, and how does it work?
The Warm Up Regulator (WUR), Warm Up Runner, or Warm Up Transmitter (depending on which BMW document you read) is an add-on device mounted to the back of the Kugelfischer petrol injection pump. Its purpose is to control the enrichment of injection pulses and supply additiona
Giving a nod to the 70’s Volkswagen repair manual that spawned countless others, my post is a distillation of several other posts on how to construct half shafts that work with the installation of an e21 LSD in your ’02. In all cases, the e21 parts referenced are the “later” e21 parts. In my case, I believe that they came from a 1980 320is. Other posts and reference material cite differences in dimensions of “early” half shafts, CV joint bolts and differential widths. See the end of this artic
Let me guess. You decided to upgrade to a Weber 32/36, got all excited about hearing that new motor roar and then discovered your manual choke cable isn't big enough for her? Well, you are not alone.
You can find several threads on the topic. @Mike Self even has one using piano wire, which if I had a piano I would've tried. But I opted to give more money to the local auto parts store and hack something myself. Sharing my solution and others might share theirs in this thread as well.
