Throttle body with twin injectors?

As the title really, does such a thing exist, I'm thinking of fuel injecting the Mrs classic mini, and what I need is a throttle body around 45/50mm diameter with 2 injector bosses. There is such a beast available but it's not exactly locost .
I know that rover did inject the mini but the system is a bit on the crappy side.

Why two injectors?

I've seen a Renault 5gt converted to injection using one big injector in a throttle body which was done by Dale from Bailey Performance,ran big power

Might be worth reading Dave Walkers book on injection systems? It covers the classic Mini and the problems injecting it

Can you do what the 8 injector boys do, one in the throttle body and one pointing into the body entry?

This is why I need the twin injectors body, it seems the only way to stop the charge robbing problem of the siamese port head.

Don't fancy doing the 16 valve BMW bike engine head swap then? Or just stick an R1 engine in it, kits available, you know you want to.

The 16v does get the old juices running but I have to be honest with myself regards available time, long term I think I will do a 16v but due to other projects in the pipeline we are talking years .

You could try Specialist Components. May not be the cheapest but will work.
