242GT If you use all period correct volvo red turbo blocks
Ahhh…. there's a bit of a caveat with that.
All (factory, road-going) 240s had either B19 or B21 turbos with K-Jet - B19ET and B21ET for Europe; B21FT for the USA / Canada, initially with the compressor outlet passing straight over the valve cover. Later on came the intercooler, and Volvo made a big selling point about that in the US, but they were still K-Jet turbos, like all factory 240Ts.
I'm not including the Volvo Turbo Cup cars as 'factory, road-going' 240s here, with their blow-through Stromberg carby.
AFAIK, no turbocharged B23 or B230 engined 240s were available to ordinary customers from factory.
2.3 litre turbos didn't arrive in showrooms before the 760 Turbo in 1984 with its B23ET and Motronic system.
If you're going 'period correct redblock' for a 240, that means using a B21 and K-Jet, and those who are not inherently masochistic would wisely avoid that expense and drama. While the B21 bit is fine, the K-Jet components are hard to find (and expensive, when and if you can) and nowhere near as easy to set up and maintain as an LH 2.4 system. Seems to me like it's way cheaper and easier to swap in a B230 LH 2.4 and pay for the engineer to do the certification.
