I think one is a double roller timing chain and one is not

I did see a company in China that offers to make the tensioners

also you might be able to make some using a 3D printer

You need to make this a group buy ...

can you even do that?
the 6cyl firing order is 1-5-3-6-2-4
so cutting the cams it would be 1-3-2-4 ??
does that sound right ??

Doesn't seem right.
On a six cylinder, 1 goes together with 6, 2 with 5 and 3 with 4, 120 degrees apart.
On a four cylinder 1&4 and 2&3 goes in pair 180 degrees apart.

So with a cut down 6 cylinder camshaft you should only be able to get the crank/cam to sync for cylinder 1.
Unless you cut it in pieces and weld it back together in the correct configuration.

Which still maybe cheaper than the billet cams..

It does. When i was in Germany, I had a discussion with a guy about this. He said cams from a supplier in England were available for the cut-down head. Piper Cams maybe?

Wonder if cams from the 16v 20XE will fit in the 24v?

 

[P.J. Romano (R.I.P.)]

Risse Motorsport is supplying cams for 24V 4-cyl engines. Not cheap though. Risse Motorsport: Aktive Erfahrung aus dem Motorsport für Ihren Opel! - Stahl-Nockenwellen mit Sonderprofilen Stahl-Nockenwellen mit Sonderprofilen A610501

I haven't gotten anywhere with Risse
I seem to remember contacting them many years ago and nothing

found at least 3 companies that sell cams (of course anytime you buy billet cams the price will be pretty high)

1)KM Cams https://translate.google.com/translate?hl=en&sl=no&u=https://kmcams.com/&prev=search

2)Cat Cams ENGINE SELECTION | CAT CAMS performance camshafts

3)Dbilas Neue Nockenwellen - dbilas dynamic

haven't found any adj Cam gears

Try these guys in London

https://www.larkspeed.com/

I bought a Kent Cams adjustable cam gear model S14 for Opel 1.6/1.9/2.0 engines (maybe more?) from them about 18 months ago. Easy to deal with at the time. I dealt with Rob Watkins at the sales@larkspeed.com email address.

No chance, cylinderspacing 93mm instead of 105mm at CIH

Cams for 16v CIH

I got cams, double valve springs, retainers and mechanical lifters from KM Cams for my 2.5l 16v build. This is a Norwegian producer, delivery time was approximately 4 weeks, the price was better than from Risse Motorsport.
I am interested in the adjustable cam gears, where did you find the pictures?

I got the pictures off pinterest (its a picture web site I guess)

I saved the pic because you never know when something will just vanish off the net

also these guys seem to say they can make some for any car

We are building special cam drives for adjustable drives on request. Send your request by email.

another thing I found out

I contacted these guys and asked them if they still supplied parts and they said yes even gave me a price for that cool looking header and the plate that seals the back of the head

crazy question does the water pump belt look like a multi groove belt?

If you mean like a moden serpentine belt, yes it does

 

[Gary]

The water pump, crank pulley and alternator all run off of a serpentine belt. I moved the alternator to the drivers side. I'll see if I can find what alternator and belt size I used.

 

[davegt27]

Gary do you plan to use AC?

this is a project I was working on for my Toyota MR2

on the left is a SC14 super charger from a Toyota Previa van (they go for around $250)

 

[Gary]

Gary do you plan to use AC?

No room for the condenser with an oil cooler there.

Here's a pic of the alternator bracket taken from my build blog.

 

[Gary]

The belt (on my pollen coated motor) is NAPA Micro VAT 25-060365

And a pic of the alternator mounted.
