Official 3 Liter 944/968 Turbo Registry (Congrats to Darwin!)
 

This is the place to post about your 3 liter (or otherwise big) 944/968 turbo motor, and to keep a list of the running motors/projects as a reference for aspiring 3 liter builders. Feel free to ask questions and include details about your motor in your post -- with extra points for pictures . If you have a running motor or project for the lists below, be sure to post or PM me a one-line entry I can copy into the list below.

Back by popular demand (well, demand anyway), below is the full list of running motors, starting in 2008, with the latest additions added and hopefully growing at the bottom:

Mine is under building process

3.2 Liter 968. Just working out the final details, should be on the Dyno in a couple of weeks for a final tune.

Does a 3.2L Turbo count or am I too big ;)

2 builds. One 3L 8v awaiting final parts before re-assembly/dyno work. Larger 16v project half done. Waiting on the world's economy to change....:crying:
Bore:106 (3.1?)
Stroke:88
Rods: Arrow
Block: 2.5 Darton dry sleeves
Mgmt: Link G4
Head: 2.5 CEP racespec w big Cam
Turbo: Borg Warner ETT 362 hybrid
E85 map.
Other stuff etc.....

Seems to be a growing group -- and yes post up all 2.8 and up motors! Would be interesting to hear basic specs. I'll start:

Bore: 104.5 (no sleeve)
Stroke: 88
Pistons: Mahle/Andial 104.5 turbo pistons
Rods: Carrillo
Block: 89 2.7
Head: 89 2.7
Turbo: VR5
Engine Management: VR
Other: Gomes cam

Bore: 108 (Sleeved, Nikasil coated)
Stroke: 88
Pistons: JE
Rods: Carrillo
Block: 89 2.7
Head: 89 2.7
Turbo: Garret/KKK hybrid
Engine Management: VR
Other:

2.8 needs rebuild this winter (some stuff already in works):

Bore: 101 (likely - stock bores are scored and still need machined, staying Alusil)
Stroke: S2 crank (is this the 88 as mentioned in other posts here?)
Pistons: Wossner (to be ordered for alusil use)
Rods: Carrillo
Block: 87 2.5
Head: 87 2.5, 944S 16v
Turbo: VR stage 4
Engine Management: VR (93oct mostly, want 100oct tune and may try e85 down the road)
Other: probably add the Saiko-michi oil catchcan, need a Tial 38mm, need a new muffler, need venturi-delete

OK, I'm in / 3ltr @7psi until it breaks in
 

Running 7psi for now. Will get back with a dyno in the near future...

Be interested to know the details on this one?

Bore: 104.5 Stroke: 88
Pistons: Mahle/Andial 104.5 turbo pistons
Rods: Pauter
Block: 91 3.0
Head: 89 2.7
Turbo: VR5
Engine Management: VR
Other: JME CAM

I have one (and its running!!) I will have to do a write up some time. 8V head, machined 968 pistons, TO4E maf,3" turbo back.

john

A bunch, many flavors! 8v, 16v, 104mm, 105mm, 106mm and one 108mm.
2.5 blocks, S2 blocks, 968 blocks.
Mostly Electromotive management

BTW - here is my 'Black Friday' picture - lots of stuff showed up on Friday. 4 TecGTs (2 going to 3.1 engines), 2 sets of pistons (one set is for 8v 3.1), a Vitesse turbo, a rather fancy dry sumpump and some other odd and ends.

Hmmm....might be able to make a '12 days of christmas' song out of that!

My build will be done by Christmas.
