Eric's "Budget" 3.0L Build

[Geronimo]

lol, I have 3 broken head studs and a desire for much more power. Life would so much easier if I had a Vette... But alas I have a love of the fancy beetles.

[detroit]

Right!... But then I'd have to trade my Ducatis for a Harley.

See you guys at Dream Cruise in August!

[mikedsilva]

I like the vibe of this thread. Following.

[detroit]

Stanglife, I live a stone's throw from Woodie, so the Dream Cruise is honestly more an inconvenience than anything else! That said I love and unequivocally support it. For all of you out there that have never experienced it, the Woodward Ave Dream Cruise is a true spectacle. It's not really a Eurotrash type of event, but that's not to say sports cars don't have a presence. I've seen just about everything. Gullwings, Ferraris, Lamborghinis... You name it. But it is truly the domain of muscle cars and cruisers. I don't know how many cars actually show up, but it's basically a car show that goes on for ten (or more) miles. At the north end they run drag races. And I don't mean 90's mustangs and the like. They've had honest to god top fuelers running down Woodward. The start line is literally about fifteen feet from an active railroad crossing. The finish line is effectively the McDonald's and gas station at the corner... That's not something you see at your average cars and coffee.

Mikedsilva, I appreciate the sentiment. I just wish the guy who started the thread would move it along a little!...
I hope to make some progress this weekend. That being pulling the head studs, and splitting the case. We'll see though. Apparently, I've been dating my girlfriend for two years this weekend. That fact may limit my garage time.

[stanglife]

We come up from Florida every year. I brought a car friend of mine last year and he loved it...his wife isn't a car person and she called it "watching traffic" lol. Debbie Downer!

We always stay in Ferndale but end up parking around Royal Oak and walking to Birmingham. You really do see a little of everything. I was into Audi at one point so my wife pointed out the "Audi lot" where there were about 5 cars, haha. Mostly domestic there.

Favorite car of all time? Camrino. Someone turned a Toyota Camry into an El Camino and had the plate, Camrino haha..

Unsurprisingly, I did not get as much done this weekend as I'd have liked. This balancing hobbies and relationship thing is tricky...
Anyway, I got all the head studs removed with no real drama. A few of those blighters did not want to let go, but they all eventually yielded. And none broke.

I did attempt to get the the crank balancer bolt out, but that thing ain't moving. My impact wrench and 160psi would not get it turning. Any input from y'all on the subject? Could a crank stop on the flywheel and an enormous breaker bar damage the crankshaft? I would think not, but better asking the question now than searching the want ads for a crankshaft later...

Here's a pic of the engine in its current state. I know; it looks pretty much looks the same as the last pictures, but I did warn that I work slow... And I have at least been spending some time cleaning parts and whatnot.

[detroit]

I did also pick up a set of Webers a couple of weeks back! Disappointingly, I'm going to have to rebuild them to some degree. Sold "rebuilt as new", the vender didn't bother to re-plate some of the smaller bits. You get what you pay for.

[detroit]

Well, it's taken awhile, but I've finally got the case split. The crank journals all look about as perfect as I could hope. As do the crank and intermediate shaft gears. So, I'm pretty chuffed about that... I hope to get a couple of solid days on the job this weekend as the girlie is going out of town. Fingers crossed, by the end of the weekend I'll have the whole thing disassembled, and the various bits and bobs ready to ship out for refurbishment.

[runner4fun]

I admire your initiative! What a great project.

[Cairo94507]

Wow, those journals look great.

[changedriven]

following your build!

[icarp]

Eric, nice project you have going here . Have you thought about the camshaft that you are going to use ? I'll post a link here from Pelican , https://forums.pelicanparts.com/porsche-911-technical-forum/1073886-3-0-rebuild-performance-advice.html
From post 10 and on there is a lot of info on CIS cam and power .
Keep at it , and you will love where you end up.

Well, it's been a few weeks since my last post. They say if you want to get something done, ask a busy person. I'm sure as hell busy, but still struggle to find time to work on this engine... I have, however managed to get the head assemblies disassembled. I've also got some bits and pieces like the intake manifolds stripped of studs, etc. and ready for ceramic/powder coating. Not to mention some fence posts dug in, a bar built and installed outside my kitchen, and various other house projects...

So, I guess I've now just about reached the point where I'll be sending the various components out for cleaning, refurbishment, plating, powder coating, and the like. I've started on a spread sheet to keep track of everything, because... there's a lot of stuff.

That said, I'd be grateful for any supplier recommendations. Ideally, I'd like to deal with suppliers local to the Detroit area, but I'm not averse to shipping. And by suppliers, I mean for everything. Parts cleaning, ceramic coating, crankshaft magnaflux/polishing... You get the idea. Please, don't hold back.

icarp,
I don't know yet what I'm doing for a cam grind, apart from NOT using my current CIS grind. I'm ditching the injection in lieu of Webers, and intend to take advantage of that. This will primarily be a street car, with hopefully the occasional track day, so it's got to be tractable. And lets face it, a 914 only weighs a bit over two thousand pounds. It'll be plenty entertaining even without a race motor.

So, I guess I'm open for suggestions. Especially from those who've walked this path before.

Also, am I best off having my current cams reground, or buying new ones and selling these? I'm guessing the former, but it's worth asking the question. These appear to be in excellent condition with the exception of one lobe (see image).

[jpnovak]

Craig Garr is in Grand Rapids. His user name is Cgarr. Does great work.

Cams... I would go with a DC40 (ModS) cam. Not sure if these can still be ground on SC cores or if you have to get new billets. Plenty of torque for your light car. Plenty of high rpm zing. Not all high rpm where you need significant oil modes. If you go with more cam the weber (40mm?) may not be large enough to support the airflow.

If you want to regrind the cams... Talk to any of the cam builders to see what is the most profile you can put on them. That one lobe has pitting. This will need to be repaired/welded or the cams replaced.

Pistons. Looks like you have Nikasil cylinders. A set of JE/CP or other pistons with larger valve pockets would be required for the cam listed above. Step to 9.5:1 Compression while you are in there.

Crank. I would cross-drill the center mains to improve oil feed to 2-5 rod bearings. This is pretty standard on a performance build.

Case. The 3.0 case should not need any machine work but should complete the usual cleaning and measuring.

Heads. The 82 SC has the smaller port heads. Open them up to 38mm for more airflow. I would port the manifolds to 37mm. The slight step (lip) will help with anti-reversion to the carbs.

[detroit]

JP,
Thanks for the input. I have heard of Craig before, but have yet to contact him. My brother is in GR, so he'd work out well.
I am indeed using Weber 40's, and do plan to bump the comp ratio to 9.5:1. I had a nice long chat with Henry Schmidt several weeks back, and that is exactly what he suggested also.
I had not heard the crank could use cross drilling, so I appreciate that little tidbit.
And I was hoping to hear that additional case machining should be unnecessary.

[Geronimo]

Awe man another Metro Detroiter, I would love to "observe" the assembly of the engine as prep for when I need to fix mine.

[ToySnakePMC]

Good thread here. Keep us informed on your upcoming suppliers and details. I have a 912E-3.0 someone else swapped a dozen yrs ago, and (sorta) look forward to hot rodding the power plant similar to your plans except for a desire for EFI TBI. Good job and beautiful 914.

[detroit]

Geronimo, it's going to be some time before I'm putting this thing back together, but when that time comes a second set of hands will likely be damned useful. Get a hold of me...
