Type IV in 1970 Bus.

[soissisc]

In my experience, the T4 engine into early bay bus fit when converted to upright cooling (and it is cool!). If you leave the stock cooling in place then yes you would have some clearing out to do for sure.

I'll just throw my $.02 in..

IMHO, the best thing you could do to your early Bus, if you want to put a lot of miles on, is do type 4.
(OK, or maybe Subaru)

The Joe Cali method is cheap, and easier if you buy some of the parts vs. making.
The DTM is expensive, super easy, and cools best.


A couple of small things, like was mentioned, a conversion flywheel,
And, in your case, an exhaust.

They even make a hanger bar just for the conversion:

FWIW, the type 4 motor is actually narrower than the type 1.
You could do the conversion with very little hackage to the bus itself.

No matter what you do to try and soup-up a type 1,
It will never have the designed-in strength and reliability of the type 4.

Thanks for all the info. Just to clarify I have the engine but not the bus. I had a good lead on a cheap 1970 roller but that just fell through. Talk about cart before the horse.
Spike, you mentioned you wouldn't use a 914 engine for a transplant. I'm starting to think so as well. My engine is a 2056 with a webcam 86 and 9.1 compression and 44 Webers. Maybe not ideal for a heavy bus even though it makes good power and torque, it may not make the torque down low. This engine is from Eric Shea at PMB performance.

Surprised you guys never see the madness...split guys use the t4 now and then, not very far off from early bay engine size...

I don't see a problem in using a 914 type4 engine in early bay. Already have it some time in my 67 bay.

I did myself a good favor in installing a motorhatch from T3 bus.

Spent quite some time to get the crossbeam customized.

914 2.0 heads are prone to cracking around the plug boss.
Even in a 914.. Especially with the 5-speed, because they got lugged.
High throttle plate angle, and fan not turning fast enough..

96 cylinders aren’t ideal for bus use either,
But many have used them.

You could run a 2056 with 2.0 heads and a Web 86 @ 9:1,
And it would really be fun, actually.

But you would have to be a ninja with tune and care.
You couldn’t be your typical lazy slob bus driver;
Out of tune, loaded to the gills, left lane, foot on the floor, no gauges, leaky exhaust, cheap gas, etc...

The trick for making 914 heads last is the Thermal Coating which really stops the plug boss from cracking to a valve seat. Otherwise yes, they crack. People have also welded in the plug boss to use smaller sparkplugs.

Mine at final install.

Clatter, awesome Bus motor build.

Here are some pics of the engine and exhaust. It currently has 1976 912E engine tin on right now. This motor was supposed to go in a 1969 912 but I may want to stick with the numbers matching engine, who knows?

Does this exhaust look like it will clear under a bus? I know it exits the other side. I can do some rear apron mods if necessary. If I do go through with this I would just look for a 1972 or later bus to simplify things.

the dilemma has never been about making HP and torque in a bus. It has to do with cooling when one is pushing a sheet of plywood down the highway at 65 MPH into a headwind - or climbing a long grade in summer fully loaded with the family, dog and all the camping gear. A 411, 412, 914-4 or 912E doesn't get this abuse. It is easier to build an engine made to scream around the track than build an engine that lasts forever in a bus. Really.

SGKent I have to agree. I have read threads over on 914World about 914's head temps near 400* from long inclines. It still amazes me that these buses can get around with single carbed 1600cc type 1's.
