And it begins... the start of the 3.2SS

[Walko]

Jamie,

In building your 3.2SS are you going to use MFI so that it is period correct with the ST

Put a blower on it Jamie...a big honking chrome blower sticking out the deck lid (just poking fun at Jamie and the "period correctness" comment directed at a GruppeB'er, Michael..smile )

[Walko]

Souk,

Didn't know i belonged to GruppeB or any other gruppe.

I know from reading jamie's previous posts on his ST build up that he went to great lengths to mak ethe car look Period correct (ie flare shapes) whilst I dont have a problem with a 3.6 in the back I am a big fan of MFI in view of the fun factor.



I look forward to all the informative discussions we have

Micheal, I was refering to Jamie's GruppeB affiliation..but we'll take you as a member too

[Walko]

What you mean to say I can join even though i am down under

I accept as long as i don't have top attend meetings on a regular basis the commute could be a bit long with the car.

I always thought Jp's car was b!tchin. I like the 3.2ss idea, thats what I am going to start building as soon as my car is painted and starting to go back together, oh and then I have to wait for dad to get his 3.6 so I can have his 3.0.

Good luck!

[Walko]

Porsche Kid,

I had a 3.2SS MFI and I wish I hadn't sold it. But hey I think the next motor will be bigger and better.

Looking forward to JPs build.

Jamie, you may wish to mention to people that may not know and get a little confused that even though the stock and larger bore is identical for the 3.0L SC and 3.2L Carrera, the 98mm pistons for the 3.0L 70.4mm crank use a 22mm pin while the 98's for the longer stroke 3.2L 74.4mm crank use a 23mm pin. Obviously, the 3.2L rods would also be needed to make an SC based motor into a 3.4L.

If one really wanted to be different, you can even machine the 98mm pistons (w/ 23mm pin) for use with the 3.6L 76.4mm crank (and 3.2L/3.3L rods) and make a long stroke 3.5L if one desires. Andial did a few 930 motors in this configuration yesteryear, but I haven't heard or seen a normally aspirated version in this configuration.

Anyway, back to your discussions and build...

Looks like fun BTW.

The madness never ends does it Ralph Don't forget the 100 mm cylinders too with a bored out case....and if you get really crazy LN Engineering will make you 102 mm jugs for a 3.0/3.2 head stud pattern

BTW, your jugs are close to being hogged out! I'm using a hand drill and a 98mm hole saw on those puppies and them I'm baking the coating on to them in the kitchen... (no really...they will be handled by some of the best in the industry)

Back to the build....Jamie....

[jpnovak]

Good points to eliminate confusion Ralph. Its still amazing how many different engine combinations are possible with a 911 case. Those engineers really did their homework.

Michael, I would love to do MFI. The throttle response is unmatched. I won't even begin to describe the sound and look in the engine bay. That being said I do have a philosophy about this engine.

I am custom building my own ITB setup. It will have a high butterfly and injector placement. I am also planning to have a 12 plug distributor that will be electronically triggered and controlled. This will give the best of both worlds. Vintage look with modern state-of-the-art performance. I will post with all the mods as the project progresses.

Now, back to my build... Oh wait, I am at work. I did mix the trashcan of TSP last night to start degreasing some of these parts. My donor motor was the dirtiest, grimiest, nastiest 911 motor I have ever come across. I scraped crud for 2 hours before I found the through bolts on top of the case last night. EEEWWW!

Don't worry, I haven't forgotten about the 100's, I am reminded every day when I turn the key. I just figured let's just leave it at 98's because that was where the discussion was at the time.

Put the damn thing together will you? You got those from me what, 4-5 months ago? What did you end up doing with the pistons? Paperweights for your desk?

Sorry to temporarily hijack Jamie, need some filler material until you post with the latest update. Think of it as a free bump.

You guys and your MFI, EFI and turbocharging. I really need to move from California.

Jamie, you should really try and find a local shop with a good parts dishwasher. I was fortunate (and grateful) to have free reign at Andial, and let me tell you packing the thing with dirty/greasy parts and coming back 20-30 minutes later and the case, cam towers, heads, transaxle, etc 95% clean was a godsend. All you need to do then is the final cleaning which will save you a TON of time.

Ralph, I agree about hte parts washer. This motor had 1/4" of muck covering most of it. No wonder this thing overheated. The tops and sides of the cylinder fins were nearly plugged. I bet no air went through these at all. The heads were much cleaner. Just a reminder to check your thermostat and breather cover gaskets.

I am just precleaning to find the necessary fasteners and to make sure I don't strip them trying to wrench through the muck.

I took out the cylinders last night. The are nearly clean. The muck just dropped off with a nylon scrub brush.

I hope to split the case this weekend. Time to find out how much damage occured on the bottom end.

Any body ever build a 98mm unit w/ 66mm crank? Would the early crank even mate to the later case?

It can be done. You could use an early 3.0 turbo case and a 66mm crank for a short stroke 2.8 (95mm pistons), 3.0 (98mm), or even a 3.1 (100mm).

[jpnovak]

HMM 3.0SS. This would be very cool!

[kenikh]

Ultra oversquare motors get my F1 jones on. How enticing is that!

[Alan.UK]

I am building a SS3.2 on a 79 SC motor with Andial S cams, 46 pmos, crank fire ignition and full SSI exhuast. I have collected all the parts over the last year. The problem is I now know of a euro 3.0 ltr motor for sale quite cheap and the thoughts of that exact engine have entered my mind.

66 crank with 98mm = a very rev happy SS 3.0ltr

[Shuie]

Alan, you would more than likely need custom pistons. Im almost positive there would be a compression drop if you used a 66mm crank & rods with those pistons. Check out Waynes original response in the engine config thread I linked earlier.

sorry for the hijack, Jamie

[Alan.UK]

Hi Shuie,

I don't actually have the pistons for my motor yet so that would not be a problem. I am selling my 98mm MM set up due to having the S cams and buying custom J&E with new 98 cylinders direct from a company over here in the UK.

Thanks

Alan
