Default Volvo LSx swap

Has anyone messed or know how hard it is to put a LSx in a 89 Volvo 740GL? It has a 4 banger in it now and it is also rear wheel drive. I like to get a idea of how much a swap would run me... I tried the search button but came up with no luck.

Take measurements to see if the motor/tranny physicaly fits in the engine bay. If it does it can be done but you would be the first one AFAIK.

check out www.jagsthatrun.com they have a list of parts and make some of the parts for this swap. it should fit, it's been done.
costs depend on how you want to do it:
engine/trans w/ PCM: $1500- $$$$$$ (all depends on what you want to put in)
mount kit $???
average fuel system:~$100-300
cooling system: ~200-400
intake: $100-300
exhaust: $400-800
wiring: $50-500
misc hoses, brackets, raw materials, ~$100-500
blood, sweat, tears, busted knuckles, etc....

satisfaction of pulling it off- priceless

edit: my estimates are on the low end, my findings are that it will cost more.

Paul Newman did SBC transplants into Volvos back in the 70s. With a MIG welder and a plasma cutter anything can be done pretty cheap. Just takes time and some planning.

Default Link to LS in a 780

I know it's not a 740, but it will show you some of the detail work.

See that would be no problem if I had those items, but I don't. I don't know how to weld so thats out of the question. I also have short temper if it don't go smoothly then I get fustrated. i'd rather pay someone sometimes....lol

There's no reason it can't be done, the LS1 will fit anywhere a SBC will, and the SBC fits the 240 and 740 like a glove

Trust me, I've thought about this swap more often than I should...my daily beater is a 1988 240DL. Then I remember that I need to buy a house, and then buy a GTO so that I can have a "daily beater" that has such luxuries as "windows that don't stick", "working HVAC", and "horsepower"!

There was a twin turbo wagon thread somewhere on here. It is the same year as you are asking about. Looked like it was going to be a really nice car. Not sure if it is done, but should be able to find the thread somewhere.....

EDIT: Found them! Enjoy!

we have a p1800 at our shop right now...the engine compartment is very small. i'd say some serious cutting would be needed for a lsx swap.

Good luck. This swap is probably not for you

The estimate above is conservative. I've got ~$6k sunk into my truck and it's been pretty much bolt-up on everything except the clutch and tranny crossmember. I didn't go overboard either. If you go with an actual LS1 w/tranny, it's not cheap once you buy all the things to install it.

No matter what you do, you're gonna get frustrated when things don't fit/go/work right or you buy the wrong parts or parts aren't fitting properly, things are not going to go right, and you will need to find workarounds and a prerequisite is having a cool temper when those things come up, or you're going to pay even more when you break something in a fit of rage.
