      Many of you have been following along the rags to riches story of a crusty old 914 that Ive been rebuilding

      http://forums.vwvortex.com/showthrea...ntown-barnfind



      Current status is pretty excellent to be honest, drives well and looks good, but it's slow... and the early "tail shifter" transmission leaves a lot to be desired in shifting feel and accuracy.

      This thread is meant to be an extension on the original. Detailing a late "side shifter" transmission and a 2.2liter flat six from a 911T. This will be a longer term project since the 914 is already road worthy and the flat 6 tear down and rebuild will not be cheap. Fortunately I have a few friends that have plenty of six experience and a full machine shop at my disposal, after hours of course. Hope you enjoy!!

      Well, I didn't see that coming!

      You're doing a full rebuild? That's gutsy. I'd absolutely love to be elbows deep into a Porsche flat 6 at some point.

      If you don't mind saying, how much was it? Also, any mods planned or are,you sticking with the stock output? Also, is it 110 or 125 hp?

      Yes, full rebuild. Its just nuts and bolts and a few special tools. I wont spill the beans on how much it was quite yet, but the deal is on par with some of the other deals I've found for this project.

      Picked it up from a friend of mine that runs Flat Six Inc. , it's a 125hp 2.2T motor. Plan is higher compression pistons and E cams, Aaron said it should be around 150hp with that, probably double what the 4 cyl makes. Best part is he said once I get it apart if anything is toast I can get a replacement from him for no charge. He's parted a few 2.2's.

      Looking at the pic I naturally assumed that would be the case, as it looks like it's been sitting a long, long time.

      No bore increase, then? You want one that sings, do you? let's see... A higher compression 2.2, 40 IDA3Cs, bigger cams, possibly a header... yeah, that'd kick ass in a 914.

      Indeed, it turns very easily and you can feel when it comes on to compression, but the internals are an unknown. Should be fun.

      That sounds really good, but don't turn it any more... unless you change the oil. Gotta remove that acid.

      That it still seems to have compression is excellent. As long as the crank and bearing saddles are undamaged it sounds like a great candidate. Especially since you can scrounge parts from your friend's stash.

      Let's see... a 2.2 is a magnesium case, correct? Your buddy will obviously know much more about how this affects 911 cases than I do, but look for signs of overheating. It's far better controlled in a 911, but magnesium gets weaker when heated beyond its limits and the damage is cumulative. 8 main bearings share the load far better than the 4 in a Type IV, but that case is aluminum and very robust. I may be paranoid because my engines are very vulnerable because of additional heat, magnesium cases and 4 main bearings... one of which only supports the nose of the crank, not the pounding from the rods.

      When do you expect to begin teardown?

      Yep, magnesium case. From the sounds of it the 2.0 and 2.2 sixes were pretty under powered for the strength that they built in these, far less instances of pulled head studs. The case will get inspected for sure, full tear down.

      Looking to start on it in a few weeks.

      The robustness of the design is light years ahead of the cheese box that is my engine case, and the magnesium alloy is probably superior, too. Are there steel inserts in the case to hold the head studs or do they go directly into the magnesium?

      I'd imagine that with 8 mains and a far more rigid crank the cases are rarely pounded out on a street car like the center main potentially is on mine.

      Best of luck, my 2.7 got more and more interesting as it was inspected deeper.
      Was previously rebuilt....by someone that didn't know what they were doing.

      Get prepared for a 5-figure project if you have to split the case. Mag cases tweak when you split them, no matter what. Just some more machine work and $ . Then you'll have the 'while you're in there' discussions.

      Having said that, I love that another nice (non stock) /4 will be converted. Welcome to the madness!

      I rebuilt my 2.7 that was "rebuilt previously" (sure it was....) and after springing for S cams and the complete teardown it was damn ugly.
      But man was it a riot after it was back together......
      Sub'd.

      That thing is gonna be nuts after you stuff the 6ix in er

      Yeah, the 2.0, 2.2, and 2.4's were fine. It was when the magnesium cases were pushed out to their maximum limits (2.7, 2.8, 3.0) that the cases started to crack and pull head studs.

      Still....You may want to get that thing X-Rayed for hairlines.

      Don't forget that most of the 2.7s used thermal reactors and were hotter running than earlier cars, so there's that.

      Small update, got it home and into the garage. I decided not to use my old engine yoke and ordered a beefier one which should be here tomorrow.




      Already collecting parts... ugh.

      -carb rebuild kits with all new fasteners
      -bulkhead mount for the engine-chassis connection
      -early 911 flywheel that will bolt to the 901 side-shift transmission

      Aaron wants the heat exchangers back since I have no use for them, at which point I'll pick up the fan housing and shroud.

      Just make sure you check those Webers for excessive shaft play on the throttles. Ha HA! Excessive shaft play.

      911 engines are absolutely beautiful when carbureted and well dressed. Do you have plans for that? Will it be a black fan shroud? What about air cleaners?

      Nah. Go full 911R/906 wafer-thin fiberglass.

      I cant say enough good things about Ollies when it comes to sending P&Cs etc out. At the very least have them do your chainboxes to ensure you are leak free.

      If you are missing a fan I have my old 11 blade that you can run.

      And I also have my old plug wires which were perfectly good if you need em.

      For weird Porsche fasteners in the correct yellow chromate Bel-Metric is awesome.

      These are Zeniths, but yeah too much shaft play is never good.

      hah, yeah. Still no heat. Boxes are there but I don't think they work with the 914-6 tins setup. Also not sure if it's possible to flip them around like that. The car has always been a fair weather driver, something to keep me off my motorcycle. No heat is just fine by me.

      No plans for dress up yet, figured I should sort the big stuff first.
