Hey all you in the Volvo world. I woke up from a dream that I had put a 5 cylinder 2.5 turbo in my 144 1967 Volvo with a 5 speed trans. Does any one know of an adapter plate for such a potential monster. The engine needs to be inline front to back. What a wonderful sound a 3 inch exhaust would make, with the load pedal on the floor.

67, 68 & 69 have a very tight transmission tunnel, you need a later model 140, that way you might have some chance of not having to cut the entire floor out from firewall to back seat.

The 2" prop shaft from the later cars does not fit in to the early car at all & it does not quite fit in to the later model properly either, I have had one hit the floor & bend. For those that don't know, the rubber diff bump stops bolted to the floor don't actually do anything. 3 pieces you can delete.

There's a guy doing a 5'er into an Amazon race car. His Youtube channel is "Throttle Stop Garage".

M90 from a 960. Cut and shut a 960 sump to match the 5 cylinder engine.

You'll probably need more than an adaptor plate, but judging from a photo I just googled, your dream could become reality (turbo):



Looks like it can even be made to fit inside an Amazon's engine bay (NA):

Thanks to all for the in put. Now I need to search the wrecking yards ro a potential car engine and get a trans to fit.

It would be a nightmare.😵

While it's fun to fantasize about engine swaps -- with enough time and money almost anything can be done but one need not be so radical to liven up the performance of the B18/20. A 1967 140 has a B18 (109 cu. in.) rated at 115 hp. and is no slouch if you are willing to use the revs it is capable of. A 140 is not a particularly heavy car - my '69 tipped the scales at Watkins Glen at 2700 lbs. With relatively modest mods a lot of performance can be squeezed from the engine already planted in the engine bay. My 144S is an example. With a later cylinder head with 44mm intake valves (my cylinder head must have come from a Canada car as it had the intake rings for a carbed engine), some minor porting and exhaust port matching, a "K" cam, compression ratio bumped to 11 to 1, and a B20E exhaust manifold. With SU's feeding it I've clocked 115 mph on Watkins Glen's back straight (from 103mph as the top speed according to a Road & Track road test of a '69 140 -- and I know that's accurate as I was ticketed at that speed before the mods - stupid me). It's perfectly docile for street driving and still gets good gas mileage (on High Test, of course). That's not to say an engine swap is a bad thing -- I've put 175,000 miles on my VolvOlds -- a 245 with a 1963 Oldsmobile 215 cu. in. aluminum V8 -- but it was a swap that seemed to make sense. The engine and trans (T5 gearbox) lightened the front enough to require lowering the front springs. But to each his own - so dream away. -- Dave
