Chasing a cam belt

[Billzilla]

Okay whoever wrote that Bosch catalogue was the product of eight generations of cousins marrying.
I looked in the Dayco on-line catalogue (www.dayco.com.au) and found that a 4G91 Lancer cam belt is a little better than what I've got here with 153 teeth, 29 mm wide, and the right tooth profile.
So I looked in the Bosch catalogue to see what they reckoned the tooth profile was on those and it was slightly different to the one they reckon the 3SGE's use. So I went searching again and found that a Hyundai something-or-other cam belt should be close .... popped back to Cheapa just then and they had one of those belts there to try.
And of course the tooth profile is quite different.
Goddamn German wankers.

I've got the guys at Cheapa to get a 4G91 belt for me to try, see how that goes and if it's not close to working I'll try Dale's suggestion.

thats where my oil pump spacer comes in handy use my dry sump pan and front spacer and feed motor into the side where the oil cooler is

Yeah.
The standard cam belt is huge at 177 teeth long.

Sat in front of the engine earlier today and had a good look at it with the old 154 tooth belt.
Set it all up and then took one tooth out of the crank pulley, I reckon it'll work so that 153 tooth belt that's 5 mm wider should work fine. I'll just have to make a new tensioner base and job done.

Best compromise was the belt from a Mitsubishi Lancer import with a 4G91 engine.

Still could lose a tooth or two but it's just not an option so this is how it'll look. I'm about the draw-up in CAD the piece of alloy that holds the pulley on the slack side of the belt to it'll work as a tensioner.
Anyway problem solved, thanks for helping blokes.

All the bits sorted and together now.
Got a piece of 12 mm alloy plate water-cut then I heli-coiled the hole where the pulley bolt goes in to make sure it won't move.
The belt is still too long as such but as I mentioned there's no real way out of it.
