Potential engine swaps?

Post by F4kus » 22 Aug 2013 02:04 am

I have an old volvo 340 1.4 lying around with a dead engine and today me and my mechanic friend were wondering what sort of 4/6/8 cylinder engine we could chuck in it (relativly easily and cheaply) for some cheap laughs? I was wondering if anyone had any experience, info or suggestions?
Also on a side note was every 340 produced with a rear mounted gearbox?

Have a search around, lots of options - probably best for some sort of Renault 16v using parts from a 1.7 340 - lots of info dotted about the forum on this. Yep, they all have rear mounted gearboxes.

Ye i have put a bit of thought into the valver but they seem to be quite pricey can pick up rv8s and essex motors for under 100 , the thought of a nice lumpy 6 or 8 cylinder motor makes me happy haha, but then i guess you gotta start swaping axels and gearboxes and such...

The rear gearbox was done for weight distribution and handling. Anything is possible but putting something like an essex up front is like using a boat anchor.
The renault F series engines will bolt in on 1.7 340 parts meaning they make more sense to use. so a volvo 440 2.0 8v on carbs is an easy swap and cheap engine to get hold of.

The 340 drive shaft is a bit special, so any mods need to keep the clutch housing preferably, or at least the clutch shaft section (cone shaped bit attached to the bell housing). Mainly you are stuck with Renault engines, which are light and powerful, but not so reliable. Make sure the 8 gearbox+diff + Engine mounting bushes are in top condition, otherwise you will just tear the driveshaft out.

You'd have to widen the bulkhead to fit a front gearbox engine and traditional prop shaft. This give the highest power options as you can fit a high power driveshaft, but is a big job.

If you can get a 360 torque tube+other 360 donor parts you can fit a 940 turbo engine and boost it up and max out the drive shaft to 250 or 300BHP.

I made a bell housing adaptor to take Suzuki Swift Gti G13B 1300cc 16v engine. I know people thinks what 1.3!? But it has over 100bhp as std and you can 8psi turbo it to kick out 180bhp. It will be with a chipped std ECU for £60. So, I can do this conversion for less than £200 as I have all of what I need... But this will be in Midas kitcar.

I think fuel economy will be good for daily driver!
