I still think the main advantage to the OB engine, is the fact that it's non-interference. And if you do end up blowing one up, you can replace the bottom end with another used block for very little money. I'd be a lot more paranoid about pushing an s4 engine to the max, knowing that if I blow it, it's going to be pretty expensive to rebuild. And more complex.

This is where many OB owners fall (including myself). I would rather modify the car that is in my garage, that is all sorted out then start fresh with a new car and who knows what problems.
Not to mention a stock S4 / GT is still underpowered, so even if your "average" OB owner looking for more power swaps models. It will not be long before they want to upgrade that one. So you might as well work with what you've got.
I do not disagree totally with your point of view. I'm just sick and tired of every OB performance thread turing into a bashing party, telling the OP to simply buy a new car.

I mean... comon! If you want a drag car, go buy a drag car!
For a 30 years old car, I can still make most common today's stock car eat dirt.
And mine make one of those sound that everybody look at! (I don't have a rear muffler... I's gone... somewhere)
And once they got their eyes on it, they can't look else where, because a 928 has one hell of a look that no car today has.
I love the sharp edge of the OB versus the smoothed corner of S4.
CIS, no computer, non-interference, just pure mechanical.
If I had to choose between an OB and a S4, I would take the OB.
Ok... I don't need 300+ hp. I admit.

Every now and then a new pony car will invite me to drag at stop lights and I politely refuse. That doesn't stop me from putting my foot in it to pass the general population of much slower cars. I've flirted with upgrading to a much newer MY, but this 86.5 is completely sorted out, minus A/C. No TB, tranny, TT, idling or running issues. Not too excited about starting over.

I think those posted 0-60 figures are off. My GTS is quicker than 6.1 sec
Anyhoo, if you can find the deal, a nice option is to yank out the 4.5L and stuff in a 4.7L ROW engine. I don't know the difficulites of going from L to K, but once the mechanicals of CIS is mastered, it beats electronic.
I purchased an 82 auto ROW back last fall. Did an engine refresh and just recently sorted out the CIS fuel supply issues while raising the fuel pressure.. This car PULLS!!!...what a blast! 300hp stock 16 valver. I just HAD to install a KD by-pass. The ROW's already have the higher stall speed converters. At some point, I will add a better exhaust system which should help the cause. All in all, I am into this car for about $3K...talk about bang for the buck! .BIG difference from my old US 82.
Dump your car while you still can. There are so many 928's available that you can easily get emotionaly tied to another one.

I see them on Ebay every once in a while. I am not sure, but I think Mark Kibort had a refreshed block and heads...just needed the top assembly. Very reasonable pricing too. Finding the top bits shouldn't be that difficult. You can always surf the Euro E bay sites.

0-62 for the auto GTS is listed as 5.9 in the tech spec book from Porsche... Normally that is full of gas at the very least. I have seen reports of 5.6 0-60 for the auto GTS and 5.4 0-60 for the 5 spd GTS...

Every year the British car club comes to town and sets up a little time trials in the parking lot behind the place were I work. Every year I go out to see them- lots of fun to see. And every year they ask me to run my 928, but have always refused( bad ball joints and tie rods-replaced this spring) BUt this year they vertually begged me to run, so I did. Mind you this is the first that I have done any kind of driving like this, and I was also competing against Louts's and tricked out Triumpes I came in second with my bone stock OB only less than 2 sec off pace. I can live with those fig's. So why would I want to get it to go any faster off the line! This lot was only about 200' square with five turns to it! Never came out of first, and held the corners very well!

I guess it's a good thing someone's out there making supercharger kits for the OBs then, huh? Haha!

I think because there are some people who build car projects based on a concept, and have no concern over cost. And exactly as you described, they may pick up a $1000 car, and toss some huge engine in it, just because they like the body style of some particular car. Very common with drag racers... In reality, those people are comfortable buying a $8000 crate engine, a frame, suspension, brakes, and then tossing some random body on it that they think looks cool. But building that race car from scratch was already in their budget.
But some 928 owners seem to be the type of people who see a really beautiful car in the classifieds, or on ebay, and the price is great. So they think they are getting this beautiful exotic car for $5000, or even less. But then they realize they are a bit underpowered off the line, and want to upgrade. But for people who were looking for a "budget exotic", they find out pretty fast that the 928 is not a car you can make fast for cheap.
My guess is that there are a percentage of 928 owners that fall into that "budget exotic" mindset. And they can't afford the mods that would make their car faster. Like rebuilding the engine into a stroker, or adding a supercharger. So for the people who can't afford to do that stuff, nitrous is a cheaper way to get the power up there. Obviously, the people who can afford to build engines from scratch, can afford a nice GT or GTS, will also be able to afford a supercharger kit, and it's no big deal. But there does seem to be some people who get into the 928 game without realizing the costs involved. And more often than not, those people are OB owners... People who can drop $20K for a really good s4 won't have an issue with spending more $ to go fast. But people who pick up a $2000 OB aren't going to have the same levels of disposable income...

After reading all the responses to this topic and others, and talking to other car people, I think I will go for a supercharger after getting the heads/valves done and replacing all of the gaskets and anything else I find in there that needs replacing or can be upgraded. That will happen over the winter. Nothing else, except maybe NOS, seems to add as much power to an OB car.
I had considered putting a 4spd tranny in it, glad I found out that would be a bad idea!
Who besides 928Performance has a website that offers supercharger kits for OB 928s?
Any recommendations on a good engine rebuild kit or gasket kit?

your best option was the very first suggestion and also the x pipe. I dont think putting in a 4 speed tranny is a big deal. I may be wrong. But I think if you have the T-tube also, you will be fine
