Yeah, well sorta, its called a 912E...

You may have better luck searching if you look for Type 4 engine. Thats whats its commonly refered to in the VW and 914 world (same engine as a 914-4 also).

Getting the right sheet metal could be a big problem

I have a 2.0 with a Raby DTM in my 68'. From a 76 914...and its a whole new car.
Seriously, the stock engines are fun and great runners, but they just cant make the same power for the same money as a T4.
It totally rocks.

I have a Raby-spec 2056 in my '69 and it is an absolute screamer. Seriously. It's faster in a straight line than my friend's '67 911S and should soon be faster on the track (updating suspension, tires, etc.)

The only problem I've found is that I severely outcorner the oil sump now and decided to take drastic measures. I pulled the engine and am converting to dry-sump, just finishing up the clean-up work on the 911 oil tank I got and it should be back together very shortly. Going to a deep-sump system or tuna-can on a lowered 912 is a bad idea when it comes to pulling into driveways and speed bumps so the dry-sump system was my only real option.

Griznant,

modify the windage tray and that should cure your problem...the Accusump alone did not do it for me...

[Griznant]

Modify the windage tray in what way?

I wasn't about to take that sucker back apart again, and I'm almost completely done with the dry sump setup. Pump is installed, lines are run, tank is getting cleaned up, holes are all drilled in the car and everything is cleaned up and ready to rock. The stock oil filter mount is gone, the case is modified for that, and since I'm using the filter on the 911 tank, I didn't need it anyway. Besides, I'm convinced that rinky-dink stock setup reduces pressure too much. The new system doesn't pressurize the filter anymore, so that's handy too.

I'll see if an extra 2 gallons of oil capacity will fix my problem. I hate oil issues.

[COLDBASS]

So do I...I put too much faith in the Accusump. The green light came on, I ignored (it will go off, it will go off, it will go off...) it, lost a crank.

Second rebuild, drilled holes in the windage tray...no problems.

The irony is that aside from a new rebuild $$$$, the simple mod seems to do the trick...no more issues thru the twistys....actually part of the problem was that that the 30 mm melling is too effecient at moving oil...

COLDBASS, can you give more info on the windage tray mod? How many holes? Where? How big? I'm restoring a 912 and have a couple type IVs and might use one of those instead of the 912 engine.

Dave,

Let me search for the jpeg, it may take a day or 2 since the wife has assigned a few chores for me this evening...

[COLDBASS]

Duh - Amazing what one finds when I search my word files under
"windage tray"....I guess I can blame it on the heat...

Dave, pm me with an email address and I shall send a pic with a sentence or 2...

Ya gots mail...

The issue I see with only fixing the windage tray is that on large sweeping turns all the oil ends up out in the heads anyway. There have been a few people who even created valve covers with "windows" in them out of plexiglass and then strapped a camera under the rear of the car to film the phenomena. Adding holes to the windage tray, would help on flatter turns, or general driving, but on the long sweeping ones, I'd think the oil would never have the chance to even get back down into the sump.

That's why the dry sump system works so well. The oil tank is always feeding the oil to the bearings, so even if the sump pickup is dry, you are still stuffing oil into the engine. It's almost as if you have the ability to overfill the engine when it's necessary, and then suck it back out when the car flattens back out.

I have no idea how well my system will work until it's all back together. *soon*

Clearly the dry sump system is a great solution. For me, the windage drain mod and the accusump together addressed my oil starvation issue. I lost a motor due to a long right hand sweeper...so the accusump by itself wasnt a complete solution.
On this second rebuild with the windage tray mod, same right hand sweep, same speed, no green light...for me, problem solved.

Type 4 conversions into 912's are easy. Check my site at http://Gumby912.servebeer.com If you have been there before but it's been a while, be sure to check the new exhaust system designed by A1 Performance. They used my car for the template.

TB,

You have mail (PM actually)
