My two cents; I'm in Calif so boost isn't an option, and I don't get the same kind of fun out a boosted car vs NA. Something about the smoothness of the power from a boosted car leaves me disappointed regardless of how rocket like the acceleration is. OTOH both of the factory turbo cars I've owned have been great on trips, especially through high mountains where NA loses power.
I've been thinking about a "budget" hot rod motor for a LONG time, have two sets of 968 pistons, and some nice cams sitting in boxes waiting for me to make up my mind on the details. I still don't know if its practical, but what fits the budget idea might be finding a rod with a smaller big end and offset grinding a stock crank to get a little added stroke with the increased 104mm bore. Combine that with some nice headers and maybe that would be plenty for a mostly street car. Thinking OB and 16v in keeping with the budget aspects.

... So it's really back to the OP. Do you want to stroke your engine or do you want to SC it?
If so, call Greg and have him help you decide if his strokers are for you or if you should choose a different route.
A bunch of us cutting into each other and going off topic isn't helping the OP

the funny thing is, the easiest way to get power and no one gets hurt, is to just mount a NOS system... easy , clean and safe, you get your 50 or 100hp really easy and and its pretty cheap. put a button on the dead pedal, push it when you want to pass...... done!

Yes for under a $1,000 you can get a 300-500 hp NOS system with 8 injectors even comes with the tap to thread the intake for the injectors....gives you the POWER for those few seconds that a street car can use it !! in less than 14 seconds you are well over 100 MPH . Not as cool as the whine of a blower or the visual aspect unless you like big blue bottles.
You could possibly plumb in three such kits and add 1,500 HP !!! oh right already one such experiment already has been done

based on a 10lb bottle giving 50hp for 8 1/4mile runs, it equated to about the full throttle time during 10 laps of a race. (about 30 miles of racing)
still kind of a hassle i know.. and eventually was illegal for the clubs i was racing with.
Slowly, the light bulb begins to glow... uber-performance-928-crankshafts-are-here
why dull for NOS. it is clean, safe and easy (but a hassle). I know , its a little Ricer...... OK, its a lot ricer!!
But at the time, it helped me beat a competitor i was down about 50hp to.... and i was able to beat him with the NOS being used. so, in the end, mission accomplished
And then goes out again.![banghead](https://rennlist.com/forums/graemlins/banghead.gif)

It's always so nice that I can count on you to be my personal troll.
How about you find a new hobby other than personally bashing on me on every single chance you get?
Try actually adding something valuable to the other people here....for once!
Take a long look....there's probably six active threads where I'm personally trying to help members fix or understand how to fix their cars.
You're doing that where? You done thst in the last six months? How aboit in the last year? Anything? Anywhere?
No, your status tells it all: "Super user", paying nothing, adding nothing.
"Super troll" would be more correct....maybe we can ask and get your status changed to that.
Does anyone, for even an instant, think that if Porsche would have built a turbo charged version of the 928 that it would have had anywhere near the compression ratio of a naturally aspirated 928?
Not hardly. Anything built, with thst kind of compression would have never made it past the first half hour of the first Porsche dyno test.
And that, alone, is what makes the whole concept such a joke.

See here's the thing:
I actually think both you and Tuomo are correct. At the same time. Each in your own context.
Small variations in the context are leading to big disagreements, name calling, troll-ish behavior from ALL parties.
The small variations in context have been forgotten and only the memory of disagreement remains. Kinda like no one remembers that the troubles in the middle east are really about water.
I think Mark Anderson (owner of 928 International) explained it the best: If you are the kind of person that loves to constantly fuss with your car and enjoys having the hood up everyday, buy a supercharger. If you are the kind of guy that wants to drive your car and only open the hood when it is time to change the oil, build a stroker.
The better-engineered F.I. kits are cost-effective within a certain context. And that context is that they will - so far at least - not have the safety features in the engine management system that modern F.I. factory cars do. That means that they will require more preventative maintenance (before it breaks) and the driver acting as the safety system.
On the other hand, a well-engineered all-motor build doesn't have any material issues that the stock engine didn't also have. It is fire-and-forget for an owner/driver that can't be or doesn't want the responsibility of being an active engine management safety algorithm.
I'm not going to try to bring more precision - other than the above - with my own observations, experience or opinions. I really can't spare the time to try to engage in the ensuing back and forth.
It just pisses me off to see folks that know what they are talking about getting into arguments because of tiny bits of missing context that aren't properly communicated or - in some cases - mentally well-formed-enough to communicate.

Mark is right. Mostly. In a broad sense. I've advised folks 'round here in Yankee Land of the same generality.

I think I would get tired of NOx, either just the basic effect or the chore of filling bottles. Drag racing a 928 is a dead end path to me, the suspension isn't made for it, and there are much cheaper better options. I want a faster 928 that still feels like a 928.
The trick to a budget build is to look carefully at what makes HP and what needs to be done and figure out where to cut a corner, like what can I do to the crank to allow cheaper options on rods and pistons, or what rods can I use to allow a stock crank and cheap pistons.
