First I'm 52, so I'm not in danger of dying of old age any time soon (knock on wood), but if I don't get it in gear and get this done I'll be too old to enjoy it. My 914 has already been off the road since 2009 and that is just too long. Life has gotten in the way these past 4 years and deciding to homeschool my two kids with me going part time work (so low funds), full time teacher (so no time) didn't help.
But I have been picking away at jobs and collecting parts and I'm pretty well ready to make the push to get it done. Also my boy has decided to go back to regular school (starts next week) and the girl is super easy to teach by herself.

I'm also pushing to get my almost completed '67 VW bug project done as well.
The bug engine is where this started, I a quest for power I began building a type 4 2.6L engine for my 914, then I got sexed up by the /6 wub.gif
I'll start a VW bug thread (later) to keep the 2 projects separate.

So what have I collected so far???

First the foundation of my build, a 1979 3.0 case, this engine began it life in a 911 with an automatic. IMO automatics have the best low wear cases.
This has been cleaned about 3-4 times and it will be cleaned a few more times before I'm happy.
Mark Henry
A job I just tackled was loctite epoxy on all the case plugs.

PanelBilly
So similar, but the kids are grown and I have a few more years on you. I'm motivated!
Mark Henry
One thing this build will have that I've never done before is full DFL (dry film lube) coating treatment on every thing I can coat, plus ceramic barrier coatings on the piston tops. these are both oven cured coatings.
I picked up a cheap mini touch up gun for spraying the coatings

Big snow storm today kids want me to take them skiing, so back to this later....Powder calls my name shades.gif

Who are you going to use for the piston crown thermo process?...never mind I just noticed it in your posting.
Good luck
Ps, I just called the # on your posting and it directed me to a Texas area code. Sorry to ask, but how did you come up with this solution vs sending it out to one of the big mfg to do this?
shuie
awesome. Thanks for sharing.

Do you have any more info on the flywheel setup? Im planning a -6 conversion and may use a later motor with the 901.

Sure.... what do you want to know? Made my own adapter ring, uses a type 4 bus pressure plate. Once bolted together it looks a lot like a stock 914/4 flywheel.

Here's the ring when I was drilling some holes, low tech I don't have an spin index biggrin.gif

I wish we had a ski mountain...we just have a little hill sad.gif

But the bright side is it's only 5 minutes away, has night skiing and we have memberships. Plus I can dump the kids there if I have things to do biggrin.gif

Getting my kit together for the balance work, a couple of questions ....

I stick with the 930 pulley right?
And the big fan pulley is for the 930 crank pulley I assume???

MrHyde
Doesn't sound too bad Mark… Atleast you didn't have to weld the car back together before starting your work.. biggrin.gif

Soooooo Lock youself in the shop, turn on the heat…. turn on the radio… and start assembling the engine.. :-) I know its much more involved than assembling a T4 but its still just measure, place component, gasket/sealant, bolts and torque. poke.gif

I'm taking my car apart again this winter for fun.. :-)

As for the ski hills. We went down to Holliday Valley in NY last weekend to try a new hill.. same drive for us as going up to Blue mountain and its a nice place… but I don't think they got the same snow as us because the hill was just a block of grooved ice.. oh well.. still getting lots of snow to play in this year. :-)

Gimme a shout if you want another pair of hands and I'll see bout coming up.

Mark, thanks for posting this thread, i will enjoy learning from it. ive been wanting to do an engine build at some point, and like others can relate to the difficulty of juggling life, family, job , job changes etc so my 914 had very little done last year + until the past month.
- also a homeschool family, at 48 , 4 kids-my son did it all the way, just turned 21, graduated in spring-had earned a full ride scholarship to USC(gamecocks) and graduated last spring with honors with an engineering degree- we bought the 914 and thought about doing a e-v conversion but found more fun in making it run!, so my 3 girls 17, 14, 9 are also home- one is easy, self learner, one not so much, the oldest now doing dual enrolement of high school/college at the tech school here- dont know it thats an option up there but here it is and is free!! except for books. So anyway just saying i can relate and wanted to get it to the driving point again too, and if we see some delays in postings we can see why, because the kids i can tell you grow up way too fast IMHO!! so enjoy it-

BTW that case looks very clean, who did that for you ?
- thinking about doing either 2056 or 2270 eventually but want to stay F.I., and my D-jet works great so i like to read up on all the variations like Zach's and now your thread.

Awesome. thanks. I just wasn't sure what needed to be done to make the 3.0 work with a 901.

I'm probably going to build an -6 engine for my next project and then decide what car to put it in. I want to wind up with something that could work in my 914 if I didn't find a car for it later. I've been leaning towards the 2.7 and smaller Mg cased engines since the flywheel should work without some kind of adapter for the 901.

mark,
I miss my 3.0 914. I did not go as far as you have with the engine. Still it ran down the Boxster S's at the track. I ran 205/50 15 tires and it could have used more tire.
Great Build

Well....a bit of squirrel progress today smile.gif

Since I'm doing the DFL and ceramic coatings I need a good oven. Last summer my sister in law gave me her old stove, I stripped off the top and everything to do with the burners. Cut off all the wiring except for the oven controls and the oven light switch.
Mark Henry
Checked to make sure it still worked.

I knocked it over and busted the dang handle sad.gif

I took it off and I'm epoxying it.
Mark Henry
I had this old top hanging around. I bent up the back and side splash...no easy feat as it's 14 gauge and I have no brake.
Mark Henry
Then I cut in the control panel smile.gif
r_towle
Ok, how did you bend that with no brake?
Mark Henry
Not quite finished, I still have to mount the top to the wall. I'm also going to mount my grinder to the corner like so and tie it into the top and wall.

I'll take the controls back out and silicone the into the top so dirt cant get in. Then maybe I'll give a quick coat of rust paint and call it done.

Two pieces of heavy 1-1/2" square tube, a vice, a couple of pipe clamps and a big fucking hammer (BFH).
Real big...as in 8lb sledge hammer and a 2lb hammer as well.
My vice is fairly HD as well...oh... and so am I. wink.gif

now you can do some home powder coating too. i can just fit a 15 inch wheel in my oven.

Don't you need to drill a hole for the exhaust flue? Looks like it was under the back left burner

It's not sitting right on the flue it's up at least 1".
I know I'll have a hot spot, but I was hoping I could get away with that. unsure.gif
This is part of my metal working area.
Mark Henry
Fired it up today with my laser thermometer pointed at a scrap piston in the middle rack.
I need to set at 320F for 300F
I need to set at 370F for 350F

The table does have quite a hot spot on the chimney area, 190F (@300) and 225 (@350).
So I'm wondering what to do..... leave it, part block it, cut a hole in the top or redirect it so I don't have to cut the top.
idea.gif
r_towle
leave it and mark it so you dont forget.

Make a sign for the door with a warning also....

nothing bad will happen if you are safe about it...its not like that counter will get damaged....though it may warp when its cold out there.....

Doh....squirrel!!!!
Gots to keep this on the front page!

Collecting more parts, thanks for passing on these Brant, and I love how Rick handled this :
