Best mod yet! S2 ring and pinion
I just put (actually, I had Karl do it since I have been slammed by work) my '86 LSD tranny that had a S2 ring and pinion gear in my '87 951... HOLY SMOKES! What a difference! It's not the best thing to do for gas mileage, but it sure makes the car a LOT more driveable and "nimble". If I had the choice to do this or add 40hp, getting a S2 r&p in my 951 would win hands down.
This is a "must do" modification as far as I am concerned on any future 951's I own. I might limit my top speed to a *paltry* 155mph or so, but its a pretty bad idea to drive that fast on the street and the local tracks won't support those kind of speeds anyway, and the low end quickness you gain more than makes up for it.
I tentatively have a buyer lined up for the 87 LSD tranny that I pulled out of the car to put this one in, so don't ask... lol If the deal falls through, I will be sure to post it here.

Scott, now you need the Stage 2 or 3 and your 951 will be totally transformed. Congratulations.
Few years back I had a 3L 951 with shorter gears AND S2 R&P, it lost top end but acceleration was awesome.

Scott,
Forgive my ignorance, but how difficult is it to change the ring and pinion from an S2 tranny to a 951 tranny. I currently have the S2 transmission in my car with the 951 engine. I have an 86 951 transmission with LSD and an external oil cooler, so I was planning on throwing that in when I had the time.
Will my car feel slower with the 951 transmission? If so, how can I swap the ring and pinion? Thanks,
