Welcome to the slippery slope..., Porsche 6-cylinder conversion Options

[mb911]

Started the teardown and did some much needed garage cleaning.

Have you thought about just doing a tidy up,replace chain case gaskets,check chains and ramps,check rocker shafts for placement,reseal the trio of leaks on the top of the engine,resurface and reseal rocker covers after valve reset relace RMS and front seal etc etc.
I really don't know if you have a core motor or a previous good runner but I bought mine with little history did the above and have a wee jem,the above also is a good indicator of general condition ,anyway you head which ever way suits (IMG:style_emoticons/default/smile.gif)

I was going to do that same thing on mine but found a stray chunk of bearing. Turns out my crank had to be reground .. Be careful if its a core it should all come apart to be sure..

So your friends with Chris, His 911 looks so good since he painted it.

Most engines are removed from the car for a reason. 50% of the "good running engines" we buy have major issues.

Started a little bit of the tear down. Head studs are all solid, doesn't seem like any have pulled but I'll know for sure once a new tool comes in and I can proceed further.

Chains and tensioners look ok-ish, of course they'll get replaced but I'm thinking there wasn't any catastrophic damage.

All matching spark plugs, good sign. Gasket sealant on the chain covers, someone has been in here before. Port matched heads to intake gaskets and presumably the carbs.

Lots of gunk and build up in the cylinder cooling vanes. Overall it's just very dirty. My cup-o-tea.

Been bagging and marking all of the fasteners, should make reassembly a breeze.

So far so good.

I have opted for mechanical tensioners on my build as there is no issues with them possibly failing. You run them a bit loose as the engine grows when it gets hot..

Kris and I go way back, early 2000's we were running around in MK4 VW GTi's, then we each had Mk1 GTi's. The 911 definitely looks great in the original Albert Blue.

[Optimusglen]

After talking with someone who's been building these engines for years, and a close friend who built one recently, they both lean toward non-oil fed tensioners, but with the safety collar. I know everyone has their own reasons, but Aaron is one of the best in the business and really, I mean really knows his stuff.

Waiting to connect with a friend that has the correct 46mm crows foot and cam holding tool so I can move forward with the tear down. In the meantime I got a nice little box from 914rubber yesterday.

That's seals for both trunks including bulkead, and all of the door/window seals. Love it.

[mb911]

Yup I am actually using mechanical adjusters and running a tad loose as the engine grows as it heats up thus the chains will get tighter.

You are nuts! LOL

You had this car on the road driving for what, a month and now you want more power? You definitely have a sickness...

I think you should just find a roller somewhere and start a GT tribute build (IMG:style_emoticons/default/wink.gif)

(by the way, I'm quite jealous!)

[Mark Henry]

There is a way to make the Carrera tensioners no fail called the Jerry Woods mod.
Just an FYI, it's what I did.

[Mark Henry]

I'd seriously take Ben up on his offer, the proper tank is a way better solution on a /6 conversion.

On the engine case I'm also in the camp of a full teardown, you wouldn't build a new house on an old crumbing foundation.
At minimum I'd get the case case savered, not timeserts, proper casesavers.

Haha, no time for a second 914. This one is great because I can drive it and have fun while I prepare the second engine.

Yes. I had planned a full teardown before I even purchased the engine. On the 4 cyl I only brought it down to the shortblock because, well, it's a 4. A 1.7 4 at that.

On the tank front there's also some news. Not sure if I mentioned it but I have access to an end mill, lathe, and pretty much entire machine shop (CNC is off limits). I made an offer on one of those Vellios "kits" on eBay, unfinished 2 halves of a tank. Need final machining and welding. Both areas I'm capable in. So I jumped on it, hard to go wrong for about $150. I will drill and tap for AN fittings. From my research the main complaints on the Vellios tanks are weight, poor welds, poor machining, and porous metal. I can knock all of those out but one and a few extra pounds are fine by me for a sub-$200 tank.

[Larmo63]

I doubt if I will do Carrera tensioners.

Slippery slope........

I'd at least recommend using some tensioner collars (guards) if not going with the pressure fed tensioners. It is easy to be tempted by the 'while I'm in there' disease to continue with modifications.

yes, as I stated that is what I am planning.

Just be aware that the collars can also fail. I'd recommend rebuilding the mechanical tensioners, you can get the kits for this.
Once done you have to bleed them to fill with them with oil.

If they are rattling don't depend on the collars, they're only a temporary safety device, service right away.

[Mark Henry]

BTW and just an FYI Ben would have given you a better deal on the tank than the ebay guy.

And was willing to barter. Oh well.

Glen I currently have one of the vellios tanks that I bought in halves.. It is not as simple as just mill,drill and weld.. The screen, plumbing has to be done or you destroy an engine in short order.

I look forward to seeing the conversion progressing.

And at 800 for a kit crazy money.
