You guys are a great help, I expected this to turn out much worse for some reason

What did you need to fit the 951 tranny into your car? Speedo/tach/etc. work?

 

Nothing, it's a direct bolt in. Your speedo is in the front left wheel.

Check out https://rennlist.com/forums/showthre...ighlight=924s3 it has photos detailing my install, plus all the great tips and help that this list provided.

 

To be honest, I was never a big fan of the 6 speed. You basically get taller first two gears -- similar to the turbo's first two gears -- and you get an extra gear in between 4th and 5th. In fact, I like the short gearing of the NA tranny -- very different feel from the 968. Unfortunately, you're much more likely to grenade an NA tranny (I grenaded the original after only 5000 miles). If I could have any tranny I want, my choice would actually to be an S2 tranny with LSD. IIRC, don't you also have to replace the bell housing to make it easier? And I'm not sure if that would fit....

 

why don't you want a turbo?
I would love to have a turbo (or supercharger) on mine
but I want a suspension more.
I need a lsd too

what all did you have to tear out to get down to 2,300 lemming?
fiberglass panels? lexan windows? dash removed?


anyway porcho, GO FOR IT!

edit: HOLY MOLY 944968.com is schweet!

edit 2: that car sounds INSANE in the first video!!! (d/l other 2 right now)

 

I'm an N/A guy, for now, I'm one of those guys who would slap on some ITBs before he builds a turbo kit for his car.

Is the S2 tranny comparably strong to the 951 tranny? I'm sure it's not 100% as strong, but much more than the N/A right?

 

The S2 trans will handle the 3.0's output with plenty of room to spare. I think that is a better choice than the 951 trans anyway, you will appreciate the lower gearing off the line. 5th gear will be a little higher in rev's on the highway compared to the 951 trans, but it is nice becauce you can be lazy with the big 3.0 and just mash the pedal to pass, no need to downshift.

The S2 trans R&P is indeed stronger than the N/A R&P. The N/A trans won't last long in a car with a 3.0 motor. Best bet is to sell it while it is still good and not full of shrapnel, then roll that money into an S2 trans.

 

I have the stock NA tranny from an 89 944. Ask anyone who knows me and they will tell you that while in normal driving I shift as if the tranny is made of glass... I have been known to get down to bidness once in a while... the old na tranny has held up well.

I think I'd go for the S2 if it's closer to the gearing of the regular na. Saying that never having driving one with a 6 speed though, so it may be just as fun. Roberto on Rennlist (do a search) has a 3.0 944 with a 6 speed, email him he'll help you.

Matt, I know you are the exception to the rule and had that in the back of my mind when I posted above. I still think that you are on borrowed time with that trans, but you knew that from the outset so that is all good. Something to consider here is the fact that you have an 89 trans. For 88 and 89 the N/A trans got the same R&P as the ROW cars and considered to be the strongest of the production 8V N/A transaxles. I think the original poster of this thread has an early (83?) car and that means he would be more likely to have steel granola if he left the stock trans in the car after a 3.0 swap.....

 

I wasn't posting that to contradict you, just to add my 2 cents from a practical (as opposed to theoretical) standpoint. My tranny had 127,000 miles on it when I did the swap. I suppose it could go any day but what on these cars can't go any day?

I agree, in that I suggest he go with the S2 or the 968 tranny if he wants the 6 speed. Although after doing this swap I would imagine a tranny swap would be a walk in the park. *Looking forward* to doing mine, swapping to an S2 when the time comes. At that point I'll go with all the LW clutch/flywheel crap.

 

Yeah, I know , just adding my 2 cents (so now we have 4? LOL).


LOL, well if you are looking forward to it, I seem to be pretty handy at grenading 944 transmissions. Just let me know when you want me to help you out by driving your car........................................

 

Yes, in order to use the 986 tranny, you must use the 968 bellhousing and t-tube.

 

Everything that is non-essentiall including drivers and passenger windows. See my thread on "924S3 Update".

No lexan or f-glass yet, but that's coming

 

If it is possible to use the 944 clutch housing on the 968 engine, (I'm not sure that it is or isn't. . .) then you would be able to keep the 944 TT and bolt the 6spd up to that.

 

You have to use either an S2 or 968 clutch on a 968 engine, unless there was a way to match an NA clutch up with an S2/968 flywheel that I don't know about. You have to use the S2/968 flywheel for the teeth to work with the computer properly (although I suppose if you used a standalone EMS you could get around that....)

Most likely, anything is possible.

 

I did the swap into my '83. I put the 6 speed in as well. If your going with the 6 speed, be sure to get the LSD.

Its a fun project
