Type I vs Type IV
Does anyone know where i can view information about a type I vs type IV engine? i want to know difference in weight to power output and torque at revs
and so on..
i understand that you get greater capacity for less dough from a tIV but im not so worried... i just want to keep the weight down and the BHP/nM
up...
ANY help greatly appreciated, even humorous anecdotes..

type 4 are about 20? kg's heavier are more reliable and make more power stock
but to fit it to a beetle you need an upright kit (about $650+) then custom exhaust also performance parts are harder to get and cost a lot more?
check out this site heaps of info on type4's

OK.. wel then thats confused me because i had my vw mechanic tell me that i should not put a type iv in if i could afford it because they are heavier
and have less torque.....
anyone else have a link to a comparison page?

type 4 air cooled engine vrs 2L type 1...
They have more Horsepower & Torque as they are a modern air cooled engine compared to the very early designed VW Beetle type 1 engine... they are
more reliable than a 2L+ type 1 engine.
Parts are $$$$$ and the oil pump is NLA.
A type 1 engine oil pump has to be modified to fit...

I have not yet got my type IV running (to go into my 63 bug project) so can't comment on personal experience re. performance. However they are
reported to have a lot more torque than a comparable type I however will not be able to achieve the same outright HP figures (according to the
type4rum on shop talk forums). They will be more reliable due to the case material used and will need less line bores. Not sure about the weight, but
probably a bit heavier.
Having almost completed the rebuild, yes they are a little more expensive, especially when you have to convert to upright, as well as new exhaust
etc...and bearings are a pain in the arse to find. So far my approx costs for the rebuild are:
2nd hand 2L $250
Machining and balancing $800
Adaptor collar for gearbox to convert to later throwout bearing $50
Headwork (convert to 1800 valves, 3 angle valve grind etc) plus lifter resurface $560
Cam regrind $110
Dual dells (40mm) inc linkage $800
Upright conversion including oil lines $700 approx
Gasket kit $90
Assembly $440
215mm flywheel and clutch/pressure plate $150 I think? can't remember
plus new alternator, dizzy etc stuff you may already have.
So basically it would be cheaper to build a type I but then again you can spend a fortune on them. I didn't have to have head work, or balancing,
or lightened flywheel etc etc. You could just bolt in a healthy 2L and away you go - just have to pay for the upright kit and exhaust. Hope this info
helps. Definitely check out http://www.shoptalkforums.com - type4rum though.

You're dreaming. GO find yourself a porshe and rebuild it.
You can do budget rebuilds on a type 4 if you only want it stock and your base is reasonable. The bottom ends are good. You'll need a set of
heads most likely. But then all you need is a set of bearings, and rings and cam. hone the barrels. reuse the pistons. Reface the lifters. That might
bump you up to around $2K. Add labour of course.
I'm in the process of doing mine right now, hoping to come away with a $1500 bill.
I dont think its worth the effort to put one in a beetle though.

chris at mick motors showed me a lightened crank case for a type 1 made from what i can only describe as an alloy (very bloody descriptive i know) it
was going to be the thing that convinced me into getting a type 1 because i was told it would provide me with abundant torque in comparison to a type
4 equivelant..
i will read the type4rums before i make any more comments/assumptions tho
cheers guys keep the help coming

Sorry Marcel, you're right, pistons and cylinders around $600 new for slightly oversize (I think 94.5mm).
Exhaust is yet to come but will be getting a custom made system so there goes another few weeks wages 
Aftermarket exhausts are available from O/S but shipping etc starts to make them out of reach. Supposedly Jake Raby (a renowed type IV builder) says
that exhaust design is critical for the type IV engine.
I'm sure there are other costs that I have forgotten though (I have spread it over quite a while to lessen the impact on the wallet). The prices
are just to help people, don't quote me on any of them!
