Let's see how much m20 heads suck.

That’s not my point, this is: How many of those engines go into E30s per year?

I don’t know but I was quoted 5.5k usd to digitise a m20 head that was hand ported and it was 1200 to machine each subsequent head so it’s not a huge initial investment so you don’t need to sell that many to recover costs

. If I was in the USA I would have done it by now, not to get rich as you won’t get rich doing product development but to bring good products to market

it’s not really any different to Rama bringing the RHD itb kit to market

Roughly looking at the serial numbers, I've done about ~2 dozen in the ~3yr they have been getting stamped.
