Engine Transplant -- Base engine from 2006 V70 into 1999 base S70 -- doable? Topic is solved

Post by **E Showell** » 09 Oct 2018, 05:34

So, I have two dead Volvos now. One committed Hare Krishna and the other was exterminated by a Nissan Rogue. Insurance buy back for the totaled 2006 wagon is reasonable. The 1999 S70 has a seized engine, but it is otherwise quite nice. Can I do a straight swap of the 2006 engine into the 1999?

Mike? Jimmy? Others?

Coincidentally I was going through my old thread tonight from about 6 years ago when I modified an 850 block to go into a '99 NA

Yes but a few items may not be a straight swap. The un-cooled sump from the '99 will have to be moved to the 2006 unless you just leave the sump cooler open and disconnected as well as to swap all the coolant pipes from the rear of the block as I'm pretty sure they differ but jimmy may recall better than me. Best practice is to remove sump and clean the oil pickup screen anyway.

I think that the 2006 VVT solenoids can stay disconnected and they should be fine. The 1999 NA should have no VVT at all. With no changes in oil pressure they won't move around and change timing angle.

There may be changes to engine mounts so best to use '99 ones.

Pretty certain that a '99 block has only one knock sensor but the '06 will have 2 points

As far as the cam sensors I think the 2006 use Denso on both crank and cams so some swapping needed there. Also you need to run only one cam sensor on a '99.

I may have left some things out. I know that later coils use a shorter boot and you may need to use '99 coils with the shorter '06 boots so electrically everything stays OK for the ECM

My recollection is that 99 has intake vvt and the 2006 with regular NA engine has intake vvt. If you have the SULEV B5244S6 then you have dual vvt and that would be a problem. The 99 has AACV idle valve device and injectors and that will have to be switched over. The coolant sensor may have a different connector and require the new style be removed from 06 engine and the 99 unit moved over.

Hi jimmy
My 99 NA had no VVT at all and hydraulic lifters. I also have a customer with a '99 NA with no VVT that I service regularly.

My 2000 NA had intake VVT with solid lifters

Of course the earlier thermostat will need to be swapped as well otherwise you'll need 2006 upper radiator hose.
You could just swap to the earlier sensor as jimmy mentioned as the thread size is the same.

I just worked in a 2004 B5244S with dual VVT

I wtook AN EXHAUST CVVT of a 99 NA and put it on my T5

I’ve got to stop spreading lies on the internet

This sure seems random...

a 2004 with dual is the sulev/pzev motor with a foam pad in air cleaner housing for hydrocarbon absorption, a steel fuel tank, and the bigger catalyst.

In Australia you were likely the different market code and likely had Bosch engine management or at least the market code 28 Denso or whatever with no CVVT. I have never seen hydraulics on 2000 or solids on 99 as built even though the S80 motors had much of the RN changes at intro.

My recollection, haven't worked on one in years, is that NA 5 cyl in s/v70 were intake CVVT too (and NA 6 cylinder in S80). Exhaust on turbos with spring for 99-2001 and unsprung intake on NA. I looked it up in VIDA and Intake is what they show.

Precopster, I'm not doubting that you have a 99 w/o cvvt but it is not a US certified model. Does that car w/o CVVT have an ETM or a conventional throttle with cable? Does it have the intake manifold with an air control valve controlling air to the rectangular air manifold that the area from injector electrical connector down to the tip of injector just above the intake hole for injector? The 99 NA 5 cylinder US models do.

Hi jimmy On Vida look up B5254S under AME profile (USA) and you'll see two identical cam pulleys part number 3531523 QTY 2.00 for the 1999MY.... Which indicates NO CVVT

The pulley part numbers change for the 2000-2001 MY with unique pulleys for intake and exhaust indicating CVVT on one cam.

All the 1999 V70s I worked on were B5254S with ETMs (I've worked on at least 5 or 6 of them)

In Australia you were likely the different market code and likely had Bosch engine management or at least the market code 28 Denso or whatever with no CVVT. I have never seen hydraulics on 2000 or solids on 99 as built even though the S80 motors had much of the RN changes at intro.

Above I stated solids on our 2000s and hydraulic on 99s......not the other way around

Our NA S70/V70/S60 99-02 are Denso

I'm not doubting you've seen what you've seen but Vida confirms what I'm saying on my 2012B version

I don't think our market has the air control valve though......

No question that solids are 2000 and hydraulics are 99 and back. I had a 99 VIN car that had CVVT and I can find parts listed both with and without intake CVVT pieces in current VIDA. VIDA has mistakes so that makes that not reliable. I agree that no CVVT versions are the norm. What we don't know yet is what the OP has on his engine.
