alright i have a 1996 850 glt wagon runs and drives great, for the exception of misfiring terribly from a cold start? any who, i found a great donor car that has the turbo engine completely stock, blown head gasket. i would i like to swap everything over into my car while doing a few light modifications to the turbo engine. Ok having said that, the engine will be out of a '99 s70. will this give me any trouble going into my car? also will it bolt up properly to my 5 speed tranny? any help/suggestions/advice would be awesome! thanks guys, this forum seems pretty neat. Devin.

 

Hi Devin, that will not work.

 

why is that?

 

Given enough time and money you can make anything work. The 1999 engine is completely different than your '96 including the ignition system (Denso vs Bosch Motronic) and all of the accessories (AC, power steering, and alternator) mount differently and work differently.

It would be cheaper to buy a nice S70 T5M than to try to make the swap.

ohh ok thats what i was looking for lol.. hmm.. none of the p.s. lines match up or anything? well that stinks..

 

and the guy told me i could have everthing that had to do with the engine, would it not be worth it or just not logical?

 

Would what be worth it?

 

First off, from the sounds of your mechanical experience, this will be WAY over your head. You're talking about swapping in an RN turbo engine into your NA. I mean, let's just start with a list of the jobs you will have to take care of:

exhaust is different
fueling is different
ignition is different
accessories are different
timing a VVT engine. What are you going to do with the VVT? Do you plug it in? Leave it unplugged?
drill out the cams for the cams for the cap and rotor
drill out the cams for the CPS
Do you know how to time a VVT engine that doesn't utilize VVT?
intercooler system
engine harnesses are different
do you know what to do with the engine mounts going from an N engine to an RN engine?
etc
etc
etc
etc

research it.

 

.....I feel like throwing up

The list of potential problems and issues is endless going from an NA N block to a turbo RN block.

 

Heck, lot simplier to fix the hg and keep the other turbo car.

 

You guys are way too harsh !!

It's just a matter of money and time. I've got a '83 Madza RX-7 with a chevy 454 in it. No one believes it till they see it.

If you have a couple of months, do a lot of the work yourself and spend a few thousand dollars on the parts you need and the custom work you'll need to hire to convert and fit the S70 engine in there you'll have a nice turbo 850.

But it's likely cheaper and easier to sell yours and just buy a turbo 850. Or pass on the 70s engine and find a wrecked turbo 850 to swap in. But that's just me.

 

a few thousand dollars really? if both of the engines have the same mounts i do not see any real difficulty in this job at all. especially since id be swapping entire wire harnesses and not hacking into the 850's original one trying to get it to work. and as i stated before id be getting pretty much everything to do it except the chassy and trans so i do not see the fuel system being an issue either. Excuse me if im coming off rude but i dont quite understand why you guys are being asses about this. it was just a simple question, and ive been ridiculed and my automotive knowledge insulted.
what gave me the idea to do this was i just did a motor and trans swap in a little honda crx, where an entirely different engine and transmission were installed in it. i see that job to have more hickups than the volvo swap.
And im not being a crybaby bitching about you guyes making fun of me lmao, i just didnt think the tiny volvo community were honestly going to shove a person away lol. But again, thanks to the gentlemen who were semi-supportive and had a little bit of help to offer because i believe thats why this website was established.

 

Nobody its insulting you or your mechanical ability...they're just trying to save you a lot of work on something that we have seen tried before. If you're still bound and determined to do it, i wish you luck.

 

Oh, the tranny is different. Have fun getting that to work and be drivable.

Man, if you have nothing else to do with your time, by all means waste 100+ hours messing with it. These cars are so cheap, I don't know why anyone would put themselves through the trial with errors. It's hard enough swapping a manual into a auto car but what the heck, like Kiss does, if it can squeeze in there go for it. And after you're done, if it all work good, you'll have a $800 Volvo 850. Let me ask, was your favorite son born in that car?

 

thanks.. and it was just a thought lol this mod is getting all huffy and puffy trying to ruffle my feathers.. but anyway, thanks you guys. really helpful. no sarcasm intended.

 

OK...I'm locking this thread before stuff gets said that shouldn't be. There's two schools of thought being put forth. Can it be done? Sure! Is it time and cost effective? Heck no. The thing to consider is, realistically, whether you have the time, money and skill set to make it happen. All too many folks end up butchering two cars for a project that never completes.
