Type 1 VW motor (New Case)

If you had a chance to redesign the Type 1 motor, What yould you change? Of course it has to fit.

I wish it came with larger bolt pattern so it can take 4" bore! Laughing

The lifter bores could use more material for larger or roller lifters.

The cam could have been lower from the crank axis line so you can stick any rods you feel like.

Other than these, it is perfect.

Thanks Nick.
4" bore is no problem but need to relocate the oil cooler return line that is between the cylinders.

I already thought of lowering the cam 1/2" and the addition of a removable oil pan so cam and lifters could be changed without teardown.
Also it can be changed to accept a 100mm stroke and still fit.

Oil filter mount?

What about the heads?

How much thicker on the lifter bores?

If the oil passages are relocated it can be cross bolted too. Very Happy

Add 2-3 inches to the bottom of the case to make the sump bigger so the oil just falls to the pick up instead of having to find that small hole to get back to the sump. (no sump needed)

Yes. A full 5 quarts with internal baffeling on the pan for cooling and antislosh.

a waterpump. Very Happy

Cross bolts will be nice.

If you are talking re-working the original case for this, you are nuts. That is just too much machine work and welding and machining. Laughing

You are better off raising the crankshaft up from the cam than lowering the cam bore. Not only cam bore but also lifter bores.

Believe me, I have looked into this also.

A good candidate for doing large bolt pattern is the non-deep stud cases...10mm. IT has the potential of getting some welding and getting reworked. The 8mm deepstuds cases is just too much work to re-do for something like this.

Heads are everywhere. It is not hard to re-weld head bolt holes. At least they are easy to get to. The case is something else though.

One thing for sure, you gotta have a full machine shop for something like this. Razz

More cooling for heads, more fins?

Dual Plug heads?

Dual intake valves

Exhaust out of bottom of head as T4 & 911

Oil squirtsers for pistons and in heads to cool exhaust valves?

Real Oil Filter

More bearing supports for Crank?

Better sealing on case for vapor recovery?

Stock CW Crank & Harmonic balancer front pulley?

Crank Trigger Ignition

Fuel injection :0)

Machine shop?
I have a machine shop.. I have a Foundry too.
Im going to cast some new WE-43 Mag cases.
I made some a few years ago and I think it is about time to make some more.

Isn't this a lot of work for nothing? I mean, the T4 already has an oil filter, great heads, and the ability to run some pretty big pistons and strokes.

Bolt on flywheel...Type 4 style

Jimmy111 · Posted: Thu Mar 20, 2008 2:48 pm Post subject:

Minniman. It is not really a lot of work. I already have the molds and patterns from a similar project. I just need to narrow the cross section a few mm.
My plan is to sell them to the builders and cast their names into the cases and heads. This way when someone says their motor was built by so and so, there is some proof. Ill sell them for the price of a new stock Mag case. Many people I talk to want to be able to change cams or service lifters. Not something you can do in either a type 1 or 4.
The type 4 is very heavy. It is a good motor but needs a lot of work. There are many more parts available for the type 1 platform and you dont need to spend a lot of money like y6ou will need to do for a type 4 installation.

I thought you were asking the question for more theoretical reasons…

Something that would be nice to have and possibly easy to add to a mold:

Extra material at the standard Full flow return spot so that one could tap in a fitting without using a 90 degree, this may also help to make sure no modifications need to be done to the front pulley tin.

In the same vane, a good place to tap in an oil temperature sensor in a main oil galley?

Beefier bottom engine tin mounts on the four corners (they seem to be striped out in many old mag cases)

A tang to bolt on an EDIS trigger near the pulley.

Still would like to have pistons oil squirters built in, any reason that would be a bad idea?

Hope those are more practical suggestions :0)

I'm going to be different. I'd change Nothing.

Jimmy111 · Posted: Thu Mar 20, 2008 7:33 pm Post subject:

I was thinking about putting the oil return on the bottom near the flywheel. That way the hoses dont need to pass by the headers.

Oil temp sender is no problem.

Piston squirters are no problem. I have them on one of my cases.

The triger mount is no problem. You have a drawing?

$ tag?

$500 or so.

millerje78 · Posted: Thu Mar 20, 2008 8:05 pm Post subject:

how would this compare with other aftermarket blocks that are available...other than the high price tag on the existing options? (eg Pauter)

do these aftermarket blocks have any of the characteristics that have been suggested in this thread?
