1991 Opel Kadett GSi Superboss

[pas-chill]

That's a very desirable car and very sought after in the Opel community. Strangely enough, every detail that distinguishes the SB from the milder Big Boss can be added or deleted. The only detail that cannot be faked is the VIN number which begins with 20XES. The "S" is extra for the Superboss. Other cars are just 20XE. The VIN number appears on various parts of the body, including, on the body under the the drivers seat.
Just peel back the carpet and you can see it.
One item that you did not mention was the LSA1 air box. It was available on the SB and is larger than the LSA2 box. So it creates a larger plenum.
As for the camshaft settings, you should really leave it on the street setting. The Race settings leaves no low-down power. It is a pain to drive in traffic.

I used to buy and sell a lot of Superboss parts, back in the day. It was the good old days, when parts were freely available. I actually took a genuine original SB motor out of a genuine SB as the owner, who had two, was doing a V6 conversion on the car.
That motor was used the in the first 20XE (20XES, to be precise) conversion in a Corsa C utility. I even ran the motor on the standard Ute management. Opel management systems are very versatile. Make sure that the management in your car emails standard.

An acceptable upgrade is the 200iE management. You will get the rock solid AFM and newer, stronger wiring.

Have fun with the new car. It will put a smile on your face and get you a lot of new friends.

Yup Is also on the car

I am intending to have some fun with the car, therefore I put the cams in race setting ... I have other cars to drive in traffic

Friends you make with every respected classic car, even with my Corona lots of people want to talk to me and talk about my car...and just look at the great bunch of guys that are here on the forum.

C'mon guys...that is not true!

I so wish people would refrain from spreading false hearsay nonsense about these and other homologation specials, dreamt up by I don't know who!

This rumour has been thrashed out in the SuperBoss group many times now and wish it would be put to bed!

The "S" in the tag simply means that the car was assembled in South Africa, nothing more!

Here is a pic of a SuperBoss VIN tag (with some of the unique numbering blanked out), and one showing a full explanation of what the details of an Opel VIN tag from Delta Motor Corporation means.

The tag does also not show "20XE" either.

The example in the document is for one of an early 2 door Kadett 1.8 GLX, and those are certainly NOT SuperBosses!

Atta boy...after all, the cams were set in the race position when they were sold to the public when new. Buy yourself a standard GSi 16V if you don't want a slightly lumpy idle and don't want it to lurch in traffic at around 1000rpm

I only just saw the latest pics that you posted now, Barry...car coming along nicely and starting to look like a real Supie, you must be itching to get it out on the road

I purposely did not comment on the VIN issues, the debate is has no end same as the 115kw and 125kw numbers on the tags.
By buying the original Supie I am now part of the Superboss owners group and I am in contact with all the guys who own an original Supie and all cars in the group have been confirmed by GM.
Just on the vin number under the seat, it is actually under the passenger seat and not the drivers seat.

Good choice...after all, the cams were set in the race position when they were sold to the public.

Ouch!! I guess that misconception has been put to bed. I am definitely out of SA for too long as that was how I remembered it. Thanks for clearing that up.

Oops, apologies if I came across too strong in pointing out your misinterpretation of the tag information.

There are just SO many untruths being bandied about concerning these limited-production cars that were developed for production car racing that I get annoyed when I see it being perpetuated on forums, thus misleading many to thinking it is true.

This myth probably originated from some sucker being conned into believing that the SuperBoss-lookalike Big Boss 16V that he was buying is a genuine SuperBoss!

Its like the common tale of the Can-Am that does 160km/h in 1st gear!!!!

Looking very nice. If I had more space I'd definitely have one of these. Relatively speaking they are still fairly affordable when compared to some other homologation cars.

An exercise....try finding a mint condition Kadette TS.
