Has anyone ever made a twin or bi-turbo A-Series possibly on a 7 or 8 port (that's the only thing I could see it working on) before, even maybe a twincam K-series?

I could only ever see it working in a clubman and anything is possible nowadays, everyone knows a bloke with a tig welder and too much time on their hands

pointless really. Just use a modern turbo well suited to your application.

Yeh but two, TWO! It's more that it's possible to rather than practical

You wouldn't benefit unless you were running a large CC and mega power. Otherwise its totally pointless and probably more restrictive.

A pair of early smart car petrol turbos would do the job, gt12 garrett type, the compresser maps look OK, they should spool up ok, and with a decent ecu should be quite a grin

The problem is small turbos are not very good and don't make much boost, once you get up above about a gt30 that's when you start to be able to make lots of boost.

The best way for dual charging is to use a big turbo blowing through a super charger. That way, you can make a 1.3 engine flow like a 2 litre, with the charger, then use a turbo sized for a 2 litre.

Dare I use the N word? I would imagine a 1293 with a GT1752/GT20 running N would be jolly quick.
