Upgrading Tii Starter. 2 Questions.


Recommended Posts

I've read many posts on upgrading from the original .95Kw starter to a variety of others. 

 

I can't conclude:

 

1.  If money is no object which is the best for cranking my tii?

2.  Is there an FAQ (tut) somewhere on installation of the same unit and electrical connection?

 

I'm hoping to unbolt my old starter, and "pop-in" a lighter faster cranking unit that has the same simple electrical connections as my original.

 

Could it be that easy?

 

Thanks for reading and replying.

 

Cheers.

SR441x out of some '80s 7series. Boneyard for $20

There is a post which gives weight and Kw's of the stock starter as well as the 440x and 441x.

Also which vehicles you can scavange hem from

 FYI on a tii .... there is a bracket which attaches to the back of the starter which goes down to the block, to provide support for the starter .... and the bracket also goes up to attach to the throttle body for support up there.

 

 Some folks use the bracket, I guess others don't ..... 

 

Cheers,

Does the SR440x bolt to the bracket, or is an adapter needed?

 

Also, what alterations, if any, are needed for the wiring?

 

Man, I really appreciate this knowledge.  I'm itching to put a better starter in my car.

 

Cheers.

I have no clue about the Tii bracket.

When connecting the 440x and 441x, connect to the correct terminal on the solenoid. It is not neccessarily the same physical terminal as the stock starter, you have to look at the markings or risk frying the solenoid. Also, the 440x and 441x do not have a spade terminal, so either put a ring terminal on your wires or adapt a spade end to the starter.

The later small case starters do not bolt to the support bracket. They are small enough and light enough to not need it, BUT you should still use it to support your Tii's intake! Also be very careful when hooking up the smaller upper connection for your Tii's cold start system. Some of the later starters have different uses for this lug, and can be power all the time, power when cranking (as yours is), or a myriad of other uses like ground! I've seen Tii's with shorted/fried cold start relay boxes due to hooking this wire up to an incorrect starter. DO your research and find a truly compatible starter.

This may help you on wiring.

Use this bolt to make your life easier.

No need to bolt the starter to the bracket for the lighter starters. But leave the bracket to support the throttle body.

My "original" starter on my '73tii finally gave up the ghost last Spring, and I just went through this so it's fresh in my mind. 

 

Personally, I prefer the "original" look, so I took my starter to a local shop and had it rebuilt. 

 

I had one fitment issue because the rear cover bushing was shot and the shop replaced the end piece (which was slightly deeper)....soooooo, believe it or not, this very slight dimensional difference caused me to have to eliminate one washer on a stud at the rear of the starter so I could re-use the throttle body bracket and have things look original.  But, other than that little snafoo, I had no issues.

 

I highly recommend having the starter rebuilt.  I have an E30 M3 starter on my '76 and it's truly a gem, especially for a carburated '02 that sits alot....cannot beat the cranking power of a later model & lighter starter...but, again, if you want originality, I'd stay with rebuilding the old unit.

Guess I should have included this picture in my first response.. Yes that is a piece of electrical tape covering the positive terminal.  I have not fitted the correct boot.

Jim,

 

With the stock tii intake cannister you won't be able to see the starter anyway!

    BMW Neue Klasse - a birth of a Sports Sedan

    Unveiling of the Neue Klasse Unveiled in 1961, BMW 1500 sedan was a revolutionary concept at the outset of the '60s. No tail fins or chrome fountains. Instead, what you got was understated and elegant, in a modern sense, exciting to drive as nearly any sports car, and yet still comfortable for four.   The elegant little sedan was an instant sensation. In the 1500, BMW not only found the long-term solution to its dire business straits but, more importantly, created an entirely new

    History of the BMW 2002 and the 02 Series

    In 1966, BMW was practically unknown in the US unless you were a touring motorcycle enthusiast or had seen an Isetta given away on a quiz show.  BMW’s sales in the US that year were just 1253 cars.  Then BMW 1600-2 came to America’s shores, tripling US sales to 4564 the following year, boosted by favorable articles in the Buff Books. Car and Driver called it “the best $2500 sedan anywhere.”  Road & Track’s road test was equally enthusiastic.  Then, BMW took a cue from American manufacturers,

    The BMW 2002 Production Run

    BMW 02 series are like the original Volkswagen Beetles in one way (besides both being German classic cars)—throughout their long production, they all essentially look alike—at least to the uninitiated:  small, boxy, rear-wheel drive, two-door sedan.  Aficionados know better.   Not only were there three other body styles—none, unfortunately, exported to the US—but there were some significant visual and mechanical changes over their eleven-year production run.   I’ve extracted t
