Re: Type1 v Type4 engines – differences/benefits between them?

If you look back through this thread, there is a pic of a shortened heat exchanger. If doing it yourself, you would need to cut through the casing (and internal fins, if any) to expose the actual header pipe. Then you would cut the header pipe to the right length for positioning the muffler mounting...

Re: Type1 v Type4 engines – differences/benefits between them?

Hi Gemmas, Well it was an old post but it seems to have come back to life recently, so no problem. If like me you use a Vintage Speed muffler (although there are one or two others that might be suitable), you won't have to modify the rear valance at all - but you will need to use short headers (J-tu...

Re: Type1 v Type4 engines – differences/benefits between them?

Haha! Oh well, it's only money - but when do we call a halt to these things? There's always something else that would be 'nice to have'!!

You won't regret it.

I was quite happy before, but now I'm jealous of your power steering!

Re: Type1 v Type4 engines – differences/benefits between them?

Nice steering setup you have there! I've done something similar myself, using the same type of rack but non-powered (see pics). Interesting to see that you have managed to retain the anti-roll bar - I couldn't achieve that with mine. However, it's all bolt-on, with no welded brackets anywhere to all...

Re: Type1 v Type4 engines – differences/benefits between them?

Yes, the Type4 has plenty of that. The Bay I fitted with the AN series 1800 engine went from a snail to a flying machine. What hills? Although I'm sure you are well aware, a Split with a more powerful and torquey motor needs a bit of tweaking in the braking, suspension and steering departments to ke...

Re: Type1 v Type4 engines – differences/benefits between them?

Well, unless you are craving more speed, staying as you are would certainly be the cheapest option. I suspect the next cheapest (and easiest) option would be to modify your 1600 to say 1835, then you would get better performance without the additional effort of having to make it fit your bus. My bus...

Re: Type1 v Type4 engines – differences/benefits between them?

You can use the shallow heat exchangers as fitted to the 411/412 cars or the deeper Bus ones, but in either case they have to be shortened at the rear end to allow the muffler to fit inside the rear valance of the bus. (I'm not sure what is fitted to a Porsche 914 - it might be worth further investi...

Re: Type1 v Type4 engines – differences/benefits between them?

A 914 2l engine with DTM cooling would be perfect. Outwardly the 914 engine is the same lump as any other Type4 unit, only the internals are different, eg. cam, valves, etc. The issues involved in fitting one into a Split are the same for all variants of this engine. The DTM arrangement gives a more...

Re: Type1 v Type4 engines – differences/benefits between them?

I can't tell you what mpg I get with the Split (as I've never measured it) but the Bay I fitted with the stock 1800 Type4 motor years ago returned around 30mpg, which was better than the stock 1600TP that had been in it. On that basis, with it being a lighter vehicle, a stock Type4 Split should retu...

Re: Type1 v Type4 engines – differences/benefits between them?

Thank you - it took a while but it turned out OK in the end. I think the main issues in the Type1/Type4 discussion revolve around ease of fitting and cost. Type4 engines cost quite a lot more to rebuild than the Type1 and good quality new parts are hard to find. The replacement cooling system is als...

Re: Type1 v Type4 engines – differences/benefits between them?

The tinware for a Type4 is quite different to the normal Type1 stuff, but could no doubt be modified to suit. However, I decided to use sheet ally. You need a piece along each side, shaped around the inlet manifolds plus the large rear piece around the pulley. Jake Raby used to supply ready made sec...
