Having recently sorted out three tiis that had sat for varying lengths of time, this is now the recipe I would advise for either sorting out a fuel delivery problem or resurrecting a long-dormant tii. I just did it with Old Blue, the '73tii I just bought that had been sitting for ten years.
Pull the pickup tube from the gas tank.
If, as soon as you open the tank up, it smells like varnish, you already know that you're going to need to systematically clean everything -- at a bare m

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
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.
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.
Pretty straightforward but figured I'd take a few photos and post. More good info here.
This is for a 1976 BMW 2002 with manual 4-speed transmission.
You will need
2 Quarts Red Line MTL
A Fluid Quart Pump
17mm Hex Driver
Tools to get a plug removed that is probably pretty stuck.

Breaker Bar
Pipe to turn a ratchet into a breaker bar.

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
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
While there is quite a lot of information on EFI conversions for our cars (some of which I will directly reference here), my goal with this article is to help anyone embarking on this type of project with a modular approach, so that one may go at his own pace, and deviate for personal preferences at any point along the way. My own project has been done on a 1975 base 2002 using Megasquirt 2, Ford EDIS, and B&G firmware, so this will be the basis referenced here. All standard disclaimers ap

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

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

Valve Adjustment for BMW 1602-2002 M10 Motor
The process of adjusting the valves needs to be done at every major service. This service happens every 15,000 miles or so. Failure to properly adjust the valves will cause increased wear and rob your engine of power.
Tools:
10-mm wrench
10-mm socket (optional)
0.008" feeler gauge
Small allen wrench or piece of bent coathanger

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
This is the story of the swap of a later transmission and front part of the propshaft into a 1967 car, to replace the broken and bent ones resulting from an exploded flexdisk/giubo.
The problems I was facing at this point included:
-shifter platform destroyed (but bent back into shape)
-front part of the propshaft bent and flange distorted
-transmission flange distorted
-mounting point for shift platform broken off the transmission
-shift rod into the transmission w
This is the continuation of the Megasquirt/EDIS installation article found here (which I apparently ran out of article room in):
This article will focus specifically on how to tune an EFI installation on your 2002. It will focus on Megasquirt as the example (since that is what I installed on my car and thus am most familiar with), but the general process is still applicable to other type of EFI setups.
Note: Before you ask, no, I will NOT share my actual *.msq files. That's a great
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.

There are basically two different types of mechanical fuel pumps that were used on '02s. The '02 fuel pumps have 8mm inlet with 6mm outlet hose fittings, and one that has 8mm in and out hose fittings that is a performance upgrade......
#13 31 1 252 506 Pump is defined by its lever type operating mechanism that is below the mounting surface and the 8mm inlet and 6mm outlet hose fittings. This pump was used on single barrel and 2002 TI's before mid '72.

I start by saying always liked "stock look” under the hood and never cared for appearance of Weber 32/36 air filter on my 76 ’02. On the technical side, Weber set up is such that air drawn into intake manifold is always warm/hot (from engine compartment surroundings). So it is opposite of air induction system was originally designed for base model. On original setup for most parts selection of warm and/ or cold air determined by air regulator housing. The original system always let outside ambie

If your shifter is a bit looser then you'd like, and you want it to feel like new again (do you know how it felt when it was new?) here are a few simple and very inexpensive things you can do to get the like-new effect. This article is based on a late 2002 style shifter. Please look at what yours looks like before ordering parts.

Some basic information about the Solex 36 - 40 PDSI or PDSIT. Jets, parts and tuning. Most of the parts are no longer available, but the rebuild kits can be found all over ebay plus many 2002 parts vendors.
Solex 36 - 40 PDSI and PDSIT were available on the early 1600, 1800 and 2002 models. PDSIT is an automatic (water) choke version and is hard to find. The venturi and jet differences are listed bellow.

After you remove all the SMOG krap , fit a new mechanical advance distributor, adjust valves, test compression, new plug wires, plugs, ignition timing set using a TIMING LIGHT , change all the fluids, wash and detail the car (that's good for a few more HP's!), and my WEBER 32/36 Jetting Prescription (actually over the counter and CHEEP!)your MPG and performance should improve.
Please purchase ANY How To Tune WEBER carburetor book, many are found right on the Automoti
Many are referred to the "stance thread" for tire and wheel fitment questions (lots has been tried), but if you are like me you may be craving more.
For those looking to get a bit more technical, i have begun to compile some resources. Feel free to post more or critique and i will add it. Eventually i may even combine all of this into a FAQ article.
