Early Type 3 Fastback,Type 1 engine conversion
Hello Thanks for reading this post.
I want to help a very long standing and trusted friend convert the problematic type 3 cooling system to type 1. We don't do hack jobs but would like
some pics or ideas on how others have achieved this . Thanks in advance for any assistance than can be provided..
We are going to be using a 2.1 litre Oxy boxer ,and its already had an IRS conversion that retained the swing axle chassis forks..

It is possible but you will need a vented decklid and a custom engine tin adapter tin needs to be fabricated to seal the engine into the type 3 engine
bay.
Should work in theory? but what is the point exactly? the type 3 cooling system is just fine and moves the same volume of air as the type 1 upright
slightly more even I think?
If it were a DTM cooling system then yeah probable a good idea to try.

IMO the DTM is a joke.
The type 3 cooling fan * Problematic
* Fans don't cope they fall to pieces in the rubber centre, it happens real quick with a 2 litre motor
* Fans are no longer available
* They run at crankshaft speed, thats too fast for this application.
thanks for thinking about it .
any input right or wrong is appreciated.
best regards
ps I love type 3's

errrr? ok? 
I think that if you build a tank around the engine and fill it with ice water, then you wont need a fan at all? Anyway thats another idea you can
try.

Why not put a type 4 engine in it?

Just curious why you think the DTM is a joke? I don't have an opinion either way but others seem to love them

The oxy boxer is far superior to an old type 4 rattler.
The DTM where do I start ? Well those that promote them are good salesmen but !!!!!!!
As I have herd someone say , I don't need to rate em, they rate themselves.
nuff said I don't want to cause friction.

This will be interesting....I totally agree with the problems associated with the type 3 fan/cooling system. It was designed to fit the car, not what
was best for the engine, The fans were collapsing 25 years ago and rebuilding isn't easy (what is?). A larger than stock cam and it's a matter of
when not if.
Type 1 cooling in a Notch, I'm sure you could do it, but routing of fresh air and sealing the wasted air out aint too easy! Also clean fresh air to
carbs.....?$%&#
I certainly don't want to start any arguments, but I have 2 DTMs being installed atm at the owners' requests. One a type 1 and the other a type 4 -
upright conversion. They haven't been run yet, but to date I can only say thier build quality is excellent, design looks to be effective and Raby's
theories/testing sound effective. I'm interested in your comment 'they rate themselves', have you seen issues with them? If so what, I may be able
to prevent them happening to my client's.

I have a customer that had one fitted , when I asked why he chose he said Jake told that they are cooler ??
I am still not convinced.

The DTM kits don't run cooler, the big thing with them is they reduce the temp difference between the cylinders more than the stock setup does.

I agree.
His testing was to equalise AND reduce cylinder temps by measuring all cylinders during testing. In his fan housings there are obvious air deflectors
that must force air flow towards otherwise hotter cylinders. His products look good to me.

yeah its a proven system, it had been developed for a long time before Jake got his hand on it and when he did he made it even better.
