Anyone have a Porsche 903 / 5 speed trans in their Speedser?
I am looking for upgrade to replace the stock Porche shifter..
which has a rather long throw.

Alan, I am not sure with the 903, but you could maybe go with a Gene Berg shifter. It doesn't look "stock", but they make them with 40% and 60% less throw. I have a Type 1 tranny wth one and it is great. It makes a huge difference and there is a thumb button on the side for reverse.

Alan, I think you mean a 901 transaxle, and yes, there are several different short-shift kits if you have a standard 911 shifter assembly. I have a "Weltmeister" short shift kit (about $100) but haven't installed it yet; quality looks very good.
George and ? ? ? ...... The engine in this IM Speedster I am mentioning is from a 1980 Porsche 911
Anyone have accurate info as to what trans was mated to the factory 1980 Porsche 911 engine ?

Could be anything Alan. What's the shift pattern like? Is 1st down and to the left with reverse up and to the left? If so its probably a 901. The 901 had 2-3-4-5 in the H with 1st outside. If 1-2-3-4 is in the H with 5th outside then you probably have a 915. I doubt if a G50 was put in there.

Forgot to mention...
I've got a 901 in my IM and I put a Weltmeister short shift in it. I had to make some changes as usually the 901 shifter is held on with 3 bolts but on my car there were three studs welded to the frame. I had to cut the studs off then drill and tap new holes for the three longer bolts that came with the kit. The kit is basically a 1/2 spacer (and longer bolts) that lifts the shift mechanism up then the shifter is about 1/2 longer from the ball down and a bit shorter in overall height.
I really like the positive, short throws now. Its like "click" into first, then "click" into 2nd, etc. I also took the opportunity to change the bushes in the mechanism. They wear out easily on a 901 trans set up and lead to very sloppy shifts.
If you have a 915 then there are other kits but they usually start about $315 and up as the 915 had some inherant problems...namely when downshifting it was way too easy to pick 2nd instead of 4th. These other kits try to deal with that problem. Remember when the IROC championship was 911's? I read once that this was even a big problem with those cars when driven by professionals!

The shift pattern for 1-2-3-4 is the H pattern and 5th is far right and up ....Reverse is far right and down- so it must be a 915.
Thanks for the information !

Pick up a copy of Excellance and you'll notice a lot of vendors selling kits for the 915. I think that Velos (spelling??) is a popular kit.
A few months ago there was a article where a guy was building an early 911S with 3.2litre and was installing a 915. He detailed all the work and parts that went into upgrading the trans for shorter throws and to lock out the downshift from 5th to 2nd.
If you're interested I can look up back issues and let you know which one???
