Sounds good :thumb :thumb
i've got plans for a set of extractors and some engines mod's.
Extractors are a good start but no heat
😢 You will also need to ditch the stock muffler.
Later down the track i may look into changing the
carbs (or is fuel injec pretty sim in price).
If you've got fuel inj I'd stick with it but IMHO it's too hard/expensive to retrofit compared with carbs.
What sort of head work ?
I'll let someone more qualified answer this one, but it's a matter of how big is your wallet.
What type of cam?
Jake Raby has something like 23 cams for the Type4 engine so that's not a bad place to start! Check out his store

and the
shoptalkforums
If you change the cam you need to ensure that the rocker geometry is correct with the new cam. Search for rocker geometry on the shop talk forums and you'll find out how to do it.
(As always) i want to keep it reliable and fuel friendly and
cost down. If u know of any good engine combo's and the best place to go for these please tell.
I'm sorry if this has been asked a shit load of times.
cheers. field.
A couple of other things to consider:
- stroker crank. Longer stroke than stock but can require clearancing so the crank doesn't hit inside the case and different pistons.
- bigger pistons and cylinders. 96mm is as big as you can go with stock cylinders and heads. Larger p's and c's require the heads and case to be opened up and can have problems with sealing and overheating.
- increased compression. VW engines tend to be low compression. Increasing the compression increases the power but increases the engine wear. A related topic is deck height (distance between the top of the piston and the top of the cylinder at TDC). Too little and the valves and pistons can hit, too much and you don't get the squish effect and more efficient burning.

PS. The above is largely what I've gleaned through reading what other people have done so take it with a grain of salt.
