New engine build

Nov 16, 2004 13 Replies

Hi Poeple



I am quite new to this group so please be kind !



I am planning on building my first engine. I have read loads on the net on how to ... performance this ... lightened fly wheel etc etc.



A few times I have come across the statement " but dont do this if its going in a bus" !



So my question is this - what would be a good design, from carb though to exhaust for my new engine.



I want not so much power/speed but tough reliable cruising at 70 - 80 MPH. Good MPG would be high on my list to.



I have read that a "square engine" ( stroke equal to bore ) is good for fuel econ. Small inlet is good for busses ? Keep your flyweel heavy (180) etc.



I will be using a spare 1300 dual port as my donar.



Any good sites I might have missed ( for bus engines ). I would prefer type 1 as there doesnt seem to be that much info on type 4 )

64 1600 split bus daily driver , 68 1300 bay bus, 78 2000 bay bus, 70
1200-70 1300 71 1300 and 72 1300 bugs.

This is going in the '68 Bus ???

Yes the 68 for now, but if its good I will do one for the 64 too. The 68 has a twin port beetle engine in that pulls better than the 1600 single port in the 64 !

Thats the other thing ! I dont want to spend to much !

Thanks for that - I will have a read.

70-80 MPH in a 64 Bus? Hope you live where there is absolutely no wind!

I used to drive my 2000 78 bay at these speeds easily. Has anyone out there got a stock or mild built type 1 engine they are happy with ( or not! ) they would like to tell me about. I was thinking 1641 pistons and barrels, 1.4:1 rockers, but not sure wether to use a longer stroke crank.

Some body must have a real life (ie not theory) view on the ideal engine for a bus !!!

2 liter T4 with a mild cam and dual 40mm carbs.

Loving it every day I drive it. perfect for a daily driver bus, and reasonably easy and cheap power that will last 3 times longer than any T1.

You don't *need* to go through the "longer stroke, larger cylinders, a plethora of aftermarket parts" -route. It's all there from the factory. (Except for the cam and carbs.. the stock carbs are crap)

OK so a couple of you think T4 is the way to go.

I am very happy with my 78 t4 2000, but the reson I was going to rebuild a type1 was , that is all that is advertised over here in the uk !

Anyone know of any UK supplyers of type 4 parts to build an engine ?

.............There's your problem. The type 4 engine was never sold in large quantities in Europe. Available engines for rebuilding and parts vendors selling affordable parts are a bigger problem compared to North America. Americans think that type 4's are common place and they're right but it isn't always true elsewhere.

tim.....where do you think most of our type 4 knowlege/adaptation(I.E. upright conversion)/many parts come from?...folks in Europe have been using the type4 in beetles, buses, etc for many years...we are *WAY* behind them....that is where people like Jake Raby, etc, have gotten the "bug" over the type 4....

.........You're right but there is still an availability and affordability problem in Europe and other parts of the world where type 4 engines were never sold in large numbers compared to here.

Hello all , again !

I have been in touch with a supplyer of type 4 engines ( there aren't many in the uk and most only sell long blocks complete )

I was advised to stick with type 1 !!! I was told it was loads of trouble - different gear box ( tranny) different input shaft, different mounting points .

Anyone had any hands on experience of puting a type 4 in a 68-71 bus ?

some sites suggest it would be quite easy ??

Rich,

That advice is correct. If you want my experiences then email me, or goggle the archives for the story.
