  1. Excellent tip, many thanks!
  2. Hi there, Looking to start (eventually) my engine restoration, i wonder if anyone has any tips or links for the the restoration of the fibreglass air duct? It's a red 3.0 item, 600 quid to replace... I guess gelcoat and cracks are reasonably straight forward to repair but what about the colour? Any tips or links gratefully received! Steve

    3.1L factory option?

    Hey Paul, For the 3.2ss i spoke at length with the guy at EBS in the states. He can supply second hand 3.2 cylinders, re-plated with matched pistons of your choice. Stretching your 3.0 cylinders isn't really a great idea. More expensive is the Mahle kit or the Nickie's kit. EBS supply all of them. 964 cams are available easily as an affordable upgrade Quote from Don Weaver at EBS Note european fuel is higher quality so doesn't need twin plugging unless you go mad on the compressio
  4. found some good gen on my hunt !! This from Porsche stuttgart classic dept hi i found this: we spook to an old master craftsmann who is retired now. He told us that the following modifications were done on these engines: -12 upper studs for cylinders changed against Dilavar-studs - cylinders and pistons changed from 95mm to 97mm (serial from 3,3 Turbo 930 103 973 00) - baffle plates from Turbo - compression ratio 9,8:1 with cylinder gasket 0,25 9,6:1 with cylinder gasket 0,5 - camshaft adjustment 0,9-1,1 - spark plugs changed from platin 260 to 265 - di
  5. Hi again, So i've been in contact with Porsche Belgium who confirm that the car and engine are matching!! It was delivered from the final assembly line as a 3.0 and the 3.1 kit was fitted in post delivery. Sadly there are no records and the dealer in Koblenz is out of business. P's and C's have been measured and are in spec so its looking good, I've been told the rings are the same as the 3.3 turbo so i'm going to order 1 set to check. Now i need to hunt down a good engineering shop to return the heads and bottom end. There was a nut missing of the oil pump and some

    3.1L factory option?

    Hi All, I just discover one.......in my garage!! I thought i had a parts bin engine but it turns out its another 3.1SC !!
  7. Wow, holy ****.........hahaha Now i started reading your comment with a bit of yeah yeah yeah...... Then i read it again...... Brain ticked slowly......It's been a long day Then i read this interesting article, https://www.excellence-mag.com/issues/180/articles/point-one#.XA_xlC2ZORs Then i went downstairs and found this !!! Block stamped as a 3.1 , uprated Bosch fuel distributer and a quick check of the original documents has it as 154KW @ 5800 and 3083cc but still calls it a 911 3.0!! Now that kind of changes the landscape!! Thanks jehatwhitland ,
  8. OK so i've been in touch with EBS in the states again.... They recommend to junk the 97mm P&C's as they are not suitable for reboring. They've offered me a secondhand set of 3.2 barrels that they will rebore, plate and match to pistons! Half the price of a new set of 98mm nickies or the 98mm Mahle Thanks very much!! One issue sorted, next heads!
  9. So this gets more interesting!! I have discovered its fitted with 97mm turbo cylinders from a 3.3!! I'm not really sure if this is the way to go!!! This is turning into a real franken-motor!
  10. Hi Phil, Ive been following your thread with great interest, almost certainly going to follow you!! Thanks!
  11. Thanks for your comments, i agree with all of that, but JE make a 98mm piston for the 3.0 with the 22mm gudgeon and the correct deck height, which, combined with a rebored (98mm) and replated 3.2 barrel should give you a tidy 3.2ss with no head sealing issues no? Anyway I'm wondering if the capacity increase is really worth the hassle, just hone, replate and fit 10.5:1 pistons with some nice cams..... I'm thinking that this is probably the way to go !!
  12. Is that right? I understood taking the 3.0 barrels to 98mm was not practical to machine due to the sealing ring issues and using 3.2 barrels at 98mm with JE pistons could be fitted directly to 3.0 conrods reusing the 3.0 heads... Anyone have experience here?
  13. latest prices from EBS in the states.... Anyone have any old 3.2 barrels for sale? Hello Steve, For a 3.0 liter based engine, our "off the shelf" pistons are available at 9.5, 10.5 or 11.5:1 compression. 9.5:1 work well with premium pump gas where 10.5:1 and up will require race fuel and/or twin plug ignition. Piston sets start at $1050 with pins, clips and rings and come with coated skirts and under crown milling to reduce weight. Cylinder reconditioning at 95mm is $1050/set. To bore and plate 95mm 3.2 Carrera cylinders to 98mm is $1100/set.
  14. Thanks, I'll measure them up next week after I get them clean!
