'99 S70 Base -- Rescue Candidate?

Post by **E Showell** » 04 Aug 2018, 10:02

Mechanic advises engine on '99 S70, FWD, Base, Auto, has seized. There is oil in the crankcase. He hasn't had time to fully diagnose, nor have I.

Car has approx. 154 K miles. It is a good candidate for an engine swap, but I don't have the time to do it.

I say good candidate because:. 1). Xemodex throttle body; 2) rebuilt steering rack, 3) Koni FSD suspension (really nice ride), 4) clean, straight rust free body, 5) all coil packs replaced, 6) center speaker dash, under seat amp and SC-901 head unit with wiring harness and 3 CD magazine.

It would make a nice daily driver if you have the time to do a swap. Alternatively, I may sell parts, but that's a less desirable option. If I go that route, I will keep the suspension.

P.M. or respond here if you might be interested.

Car is in North Western NJ and would need to be towed.

Seems like there are always "bastards" waiting to be saved...

Is it possible to drop a 98 S70 engine in? (Our car could certainly use a newer/nicer body!) Is it just a swap of computers, installation of throttle cable, and other stuff? Or is it completely impossible?

It should be possible, if they are both NA or both turbo. AME S70s, both years used the B5254T & B5234T3 for turbo charged cars. "98 NA used the B5254FS, '99 used the B5254S.

Edit: Read too fast, corrected engine ids.

B5234FS? I think the NA uses B5244FS/B5244S. NA cars are 2.4 liter.

If it's a '99 it shouldn't have VVT, so there is no need to worry about that. ETM/intake manifold will swap right over, among other things. You should be able to just "delete" the distributor and put the black cap in the back of the cam. It should be swappable.
I'd definitely swap over the M56 too! Very direct swap on FWD cars. I had the bright idea to swap an AWD...

Hopefully somebody buys this car and fixes it up, NAs aren't all destined for scrap/part out just because they're missing a turbo!

Read and wrote too fast. Edited above to correct engine ids.

The B5254FS & B5254S are the same displacement as the 2.4 (2,435 cc). I think they rounded down for the European market to save the customer on taxes. Rounded up for the AME market so we could believe ours are bigger.

The B5234T3 is a 2.3 L (2,319 cc)
The B5254T is a 2.4 L (2,435 cc)

Yes, they are the same engine. Just keep the ETM, manifolds and accessories from the 99, delete the distro as per above. Drop it in.

Front seats are rough, but I have the Greek seat covers on 'em.

Same idea as BMW calling a 2.5 a 2.3 in the Z3. Just playing mind game to get people to pay for the 2.8. Or just about ANY car company's naming strategies today!

I believe MY 2000 used the B5244S once the VVT was added, but those seem to be correct.

The !999 base I parted out had exhaust CVVT, so this one might be CVVT too.
