3L 16valve turbo - list of ready-made parts?

[Tom]

944T with 3.0L 968 block, 8V with 944T parts behind it all the way to the transmission.
Evenything bolts up, BUT, the flywheel doesn't sit in the bellhousing in the same position. It's about 1/4 inch back, so the speed and ref sensors will never line up. I googled this a dozen different ways and it seems that bolting a 944T (SPEC Performance) flywheel to a 968 crank will result in the flywheel being set back a bit. I checked for TDC and the flywheel does not sit directly above the inspection slot at the bottom of the bellhousing, It's hard to find, but with an angled mirror, I could see the timing mark, so TDC is accomplished. But that doesn't help the sensor alignment. Someone else must have built a 944T with a 3.0 block with 8V head and 944T parts behind it. How'd you solve this problem? Do I have to use a 968 bellhousing and torquetube? Thanks

I have a 104mm block, 88mm crank, 8V head, and and everything lines up just fine with the factory 951 flywheel and bellhousing. As 3 liter turbos go, it's as close to standard as it gets. Have you compared that flywheel to stock?

OK here goes. Granted AI has a lot of goofy info out there, but the following AI description makes sense given my situation.

OK, there you have it. Makes sense. The only other explaination is that the Spec flywheel mounting causes everything to sit back 1/4 inch. But I only know one way to bolt the flywheel to the crank.

Ouch. Any thoughts?

Did you see my post above? Using a 104mm block ('89 2.7/S2/968) with 951 flywheel, 951 clutch, 951 bell housing, 951 torque tube, and 951 transaxle has been used by many without issue, myself included. I think that's a swing and a miss by that AI engine -- probably inferring the 1/4" misalignment from your prompt and the fact that the 968 bell housing is indeed different. However, if you use all 951 parts behind the block/crank, you should be good to go. If yours doesn't line up, I'd suspect the flywheel. Which flywheel is it exactly? Try a genuine 951 flywheel...

Please dont listen to AI, Im using a 968 block with a 944T flywheel/bellhousing with no issues. You definately wont be able to use a 944T flywheel with the 968 bellhousing and the 968 flywheel has the wrong tooth count for the 944 DME

...Like a lot of folks, I'm learning, asking questions. Looking for answers where ever I can find them. Looking for solutions that hopefully don't involve tearing apart all the work I've done. Have a nice 4th.

Hi guys, I cleaned up this thread to redact the AI-generated miscue and associated commentary -- to maintain the overall carpokes way and prevent the spread of wrong info. In fairness to cp99, it's probably better to start a new thread to discuss unrelated issues on other builds -- Johns944Turbo, I'm sure a lot of people would be interested to hear about your motor!

Based on my research, stock 951 rods should be plug and play and they are forged.

Most stock 951 rods after 86 aren't forged.

Hey Tom, Thanks for your reply.
Regarding my 3.0 turbo build, I started this project many years ago. Too many to admit. As many DIY Project folks know, Family, Kids, Job, Other Priorities, Money, Health etc get in the way. I installed my ill fated clutch 7 years ago and I'm sure I compared it to the original. I was also very careful to align the sensor bracket. So, how could I have missed the FW not aligning correctly? Dunno, too long ago to remember. Anyway, it appears that I will have to undo my under car work: exhaust, halfshafts, drop trans, pull torque tube, stater, slave, yoke, just to get to the bellhousing. FYI, I moved in the interim and can't find the clutch receipt, so I don't know the FW/clutch part #s or who I even bought it from (purchsed over 7 years ago) . That would have made diagnosis a bit easier. Anyway, if anyone can offer a shortcut to disassembly mentioned above, I would appreciate. Crawling around under the car isn't as easy as it used to be. Thanks all.
