240 turbo

I've been pondering this. I have the turbo K-Jet fuel system from a 242 Turbo, allegedly the only 242 Turbo ever to reach Australia (Volvo press car). The way they set it up in that application is they have the fuel metering flap pre-turbo, then run long injector lines over to the injectors. The intake manifold is different, you could probably just use the manifold from an EFI 240, and the injectors have extra brackets over them to stop them popping out of the head under boost. You also have a different control pressure regulator.

I don't think I've seen any +T K-Jet cars to be honest. Most people probably would swap to EFI these days.

Back in the day, an Australian company made turbo kits for the 244. I guesstimate say 10. I had a similar kit with a big Rajay turbo and K-Jet. Boost was just 5 psi.
The turbo was on the LH side close to the airflow sensor plate. The std engine exhaust manifold was used and then exh pipework went under the engine and up into the Rajay. Turbo lag was bad as the once hot energetic gases had too far to travel to spin the turbo up efficiently.
The turbo exhaust out then went down the left firewall of the engine bay as there was room before crossing to the std exh pipe. So no steering shaft issues at all.
The airflow sensor plate / fuel metering was at the left front of engine bay. Compressed air from the turbo was pushed straight up into the k-jet manifold.
On the road with a manual gearbox and O’Drive, once the turbo eventually became efficient it was a real smooth push in the back that only a turbo can achieve.
I have a bit more info on the above, deep in the archives.

Years ago at a Volvo multi club event I got talking to some of the Victorian people and the subject of Volvo Australia importing 6 x early 1980's 240 4 door turbo sedans into Australia , I remember seeing a photo of a brown or burgundy one under a tree.
Does anyone know anything or heard about these cars ?

242GT Does anyone know anything or heard about these cars ?

Yeah, Heino Nowatzky from the Volvo Club of VIC knows the story about them, or rather it - the only known RHD factory 240 Turbo in OZ.

The story is that a dealer imported 6 turbo kits and fitted them to 240s then sold them. one is known to still exist, i have seen it, it looks like a normal 240, nothing very special. where it is special is that it means a 240 had a turbo 'new' (even if dealer fit) so they can be registered in Victoria.

Do you know what year the dealer brought the 6 turbo kits in , I've just put my 242GT Turbo on historic plates and had a bit of push back about it being turboed , I showed ghe a chart I've got listing all cou tries models etc and mention the 6 240's in Victoria but as I've lost the photos I had it all came back to hear say , in NSW historic plates are 30yrs

Oddly this came up a couple of days ago and there is a story of another of the 6 being in another workshop under a cover. I will ask around about them and attempt to get some photos and permission to share them. More to come (ideally).

Free The Victorian 6 !!.

This is an interesting discussion, I've been considering registering my GT on club plates but the idea hasn't been received as well as I thought. This surprised me a bit because I have a couple of classic bikes on club rego and neither are completely standard. If I can establish that there were turbo 240s here then it might just sway the discussion in my favour.

Which state?

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.

Paul_Roodenrys just put it on the Classic Vehicle Scheme instead of historic. A standard looking turbo setup is unlikely to generate any questions when trying to get a blue slip without am engineers certificate

Can confirm. My 77 245L runs a B23ET with LH2.4 and I was able to blue slip it back in 2018 with next to no drama. Explained to the certifier that 240 turbos existed in other markets, he went over the car and printed off the slip with the updated engine number. Has been pink slipped every year since then without drama. It looks mostly stock so that helps.
