Did it draw through both throats of the Weber, or just one?
A friend built a Holden van showcar back when they were all the go. [1970's] It had a 202 six with this same setup & it sucked through one throat only. Went quite well too.

Both throats worked all the time - on a cold night during a quick fang up to Mount Lofty, I'd pop the bonnet and the whole manifold would be glowing red hot and the weber adaptor would be covered in ice...

I miss that car...

Yes, I saw the other photo's & I can now see how you had it setup.

With a turbo, you get a nice steady, pulse free flow on the suction side & carbs will flow, & mix, much better this way than with pulse flow that you get with one throat per cylinder. No spitback, just a constant stream of air & all of it flowing in one direction all the time.

mmmm very nice, what boost were you running and howd the l20b hold up, stock internals or fancy? very interested!

I remember... I reckon this was the first turbo datto I ever rode in... Twas quite quick from memory!

Cheers. Adam.

Ya - and standard brakes made for brown undies You might remember that Adam or was that Charles?

Boost was 7psi and the L20 was stock as a rock but strong - it came with a copper head gasket but when I rebuilt the motor (was DOA when I bought it) I didn't put it back in...

I regret sekking the car to this day - I sold it for $3000 (interior was smick and body was above average) with a rebuilt motor 5000k old, rebuilt turbo.... and bought a bog stock RX3 sedan


About a year later it was in the Trading Post again for $2900 but I didn't have the cash then (just put a 12A turbo in the RX3)
