Swap 1999 S70 NA engine into a 2000 V70 XC

Post by **bskeels** » 12 Apr 2012, 19:07

I was wondering if there would be any differences to swap a 1999 S70 NA engine into a 2000 V70 XC car? Would there be any electrical sensor issues? Are there any engine differences that I should take into consideration? The head is bad on the V70, has been machined once, I have access to a wrecked S70 with a NA engine. Thanks

Too much work and too much money to make it work, not to mention you'll be taking a step backward.

Nor will the head from the NA work on the XC engine.

The turbo to NA engine swap is a major undertaking, large investments of time, money and expertise to make it work. Just to make the car slower! Pretty sure I have never heard of anyone making an XC into a non-turbo, FWIW.

I'd try to find a turbo engine or head from a 99 or 00 (or likely other years will work too, I am not expert on the 99+ cars).

I think they sold a non turbo version of the XC70 in europe at one point. You'll have to sort out a lot of engine management issues. Its not worth the effort. At least find another LPT engine.

How valuable is time and money? And how much is the NA engine worth to you? Even a free engine with this much work can cost more than getting the right replacement. You can almost guarantee needing to at least reprogram if not replace the ECUs because neither one is likely to work. I would say swap out the ECU and harness from the NA but I doubt the other modules will play fair. Besides, you don't know what problems you are inheriting from the wrecked car. It would take a lot more than dropping in the right engine, which in itself is a lot more than dropping in the right head.

I'm not sure if it was offered here in Europe at all, but if it was, it was the B5244S-engine with 170 hp, that's the new NA engine from 2000 onwards with ETM etc., not the old wire-throttled engines.

can this engine still be hooked up to the turbo since the car it is going in has all that equipment?

No. The compression ratio for an N/A motor is 10.3:1, for a GLT it's 9:1. See the difference? Your first application of boost=catastrophe. Not to mention the problems you will have hooking everything up.
Find a 99+ GLT engine and use your turbo and manifolds; that way you won't spend a fortune. By doing that you're much better off and on the road sooner than you would be trying to fit an N/A.

Yes it can, everything will bolt up but you will have to run a strict diet of 91+ octane at all times. I've seen turbo engines live long happy lives at 11:1 CR and since this is an LPT engine you're not running that much boost anyway.

Will a vin code 58 engine fit inplace of a 56 engine?
