modified 164
hi all bit of a lurker,i have the chance to buy a very tidy 164 straight 6...
i love the shape,but was wondering is there an engine swop kit as such...for sat fitting the newer 5 cylinder 20v turbo or something else...cant seem to find many modified ones...there must be some around...thanks...

The obvious is a 6 cylinder 960 engine much lighter and more powerful ... but the original 164 engine is so silky smooth .. once you have the gearbox you could then fit any volvo alloy 4 , 5 or 6 cylinder engine from the 1990's

Reason there are few modified ones is that the B30 is an excellent and powerful engine. With a few mods it can be made more so.
Don't exchange engines you will only devalue the car and achieve nothing.

difficult one , i assumed there was some problem with the original engine , its not that powerful at 145 bhp and going to one extreme , a volvo T4 4 cylinder turbo engine weighs half as much and can have nearly double the power with reasonable economy .
On the other hand keep the original all cast iron engine , The marine version with 3 stromberg carbs is 175 bhp ( same as the 164E injection version ) Or you could fit 3 x 45 dcoe weber carbs and tubular exhaust ...If you can find a 6 cylinder performance camshaft and a few minor head mods you could make over 200 bhp .( same power as the 960 6 cylinder ) however expect drastic fuel consumption!

has anyone heard of a 5 pot 20v turbo engine being fitted...

Better to buy a Subaru Impreza.....

How much power are you aiming for? Unless you want huge power, don't assume you have to dump the b30. This one has triple weber 45 carbs and I think I remember reading it has circa 200bhp.

Mine is having a supercharger and mapped fuel injection.... but it's in peices at the moment!

There is no reason why it couldn't be done, I have seen pics of 140's with 20v turbos so the principle is roughly the same, assuming you are handy with electronics. Tuning the existing B30 or the swap would both be interesting upgrades, Its nice to see a different spin on the older models, particularly if it means a vehicle otherwise unused is put back in the road again. The Retro Rides forum can be a good source of inspiration. Good luck & keep us posted whichever option you choose.

Chevvy V8 anyone?

On a similar vein, what would be the most cost effective way to get a bit more power out of a standard B20b without compromising its driveability
