The problem with the motors other than the B5254T4 and the B5244T5 is that they dont have forged internals (correct me if im wrong). They cant take power like the R and T5 ones do. Not sure if the 2.3Ls need special tuning but generaly the 4T4 and 4T5 swaps dont. Id say keep looking. The 4T5 is worth it. Check with Re-Volv, Carpart.com, and other online junkers and Volvo junkers.

 

The R engine comes with forgd rods but the pistons are cast. Wiring harness, ECM, And ECM software may be a problem. I'm sure it's possible with enough thought, And work.

 

Not that hard to find an R engine... Why not just put another one in?

The 2.4 T5 has the same bore as the 2.3, only the stroke is longer.

Swedish do high performance 'Frankenstein' builds ;

2.3 engine
Crank of the 2.5R
Original 2.4 pistons
Head of the 2.5R with VVT

Even the 2.3 pistons have proven to withstand +400hp, there is no absolute need for forged pistons, stories that you need Wiseco pistons are hear-say-nonsense

So if you are in a hurry, get a 2.3, use the crank of your 2.5R and build the engine as desired.
if not, have patience and wait/look for a 2.4T5 and dont open it

 

This is how I've configured my build for my 850, 2.4 LPT engine which has a higher not lower CR, longer rod and shorter piston to pin height and a lighter crank to boot. 2.4 LPT engines should be abundant and with a proper tune, you'll be much happier than any other option with the lowest cost.

 

I dont really want to put an R engine because its kinda crappy. From what ive read people have nothing but problems with them, either headgaskets or worn cylinder walls.

So it’s a no-go for the 2.3T5 as a drop in replacement?

Never head gaskets. Shim block and you'll have no problem with cracked sleeves on a stock motor. I've never heard of cyl wall wear either.

As far as a drop in, yes. Meaning no a 2.3 T5 will not work out of the box.

Your car has dual VVT, a 2.4T5 also has, but the 2.3T5 doesnt, so you would have to switch heads.

Rebuilding with a 2.3T5 would be the most time consuming of the 2, but cheapest and strongest option though.

 

The time and effort to put in a different engine would probably be worth the price of 2 replacement R engines.

 

With all the people tuning T5 and LPT engines to same power levels as the R I don't think it would be much of an issue to swap one of those engines in.

 

Engine costs more, and you need a tune. All that work to get to the same power as a stock R is a bit silly. Unless you're building for a lot more power... I would just stick to a good used R motor with shims.

I know that the LPT engines would run the car, but they have a lower CR.

No they actually have a higher compression ratio. the LPT B5254t2 has a 9.0:1 CR. The lpt would work for awhile till it cracks a cyl. I love how the lpt feels, and am looking forward to getting my k24 on my s80.
I just picked up a 05 T5 engine for my R but it wasn't cheap lol. Could just pick up another R engine for it I see them for sale usually cheaper than the 05-09 t5 engines.

 

damn, ya I messed that up. My main question now is, would a lpt engine plug and play in my R? What lpt is better a 2.5 out of a 2003 XC70 or a 2.4 out of a 2001 XC? Both are available, and confirmed running engines at my local junk yard. Otherwise I can be patient and wait for a 05 + T5.

If for example it died in a couple years, Ill be cool with that. Would give me time to build up a nice 2.4, in the meantime I want to sell my beater Civic, and drive the R.

 

You must be reading things pertaining to “school-boy” racers pumping them up to a point that makes them unreliable. There are bunches of 04-07 R’s with 200k+ and trouble free, other than standard maintenance. And there are more and more in the junk yard due to the cost to repair that avaerage fender-bender on any Volvo today in the eyes of the insurance companies.
In stock OEM configuration other than an exhaust/intake and maybe a mild tune, I have a friend with over 230k on his.
It will cost you more to reinvent the wheel in swapping another Volvo engine into your new V70r wagon than buying a junk yard more.....

 

Hmmm, yes there are a bunch of trouble free ones out there, both stock configuration and tuned.
But also stock engines who went bust, so that doesn't say anything.

The easy road may not be the most sensible, there are members out here who did a 2.5 swap 3 times, could be bad luck, but in the end you are always taking a risk with a (unopenend) junkyard engine.

Bottomline, 2.5's are fragile, if you want a reliable S60/V70R you have to invest time and money, part of driving such a car, otherwise you better pick another model/brand.

Cheap, fast and reliable...pick 2

 

Hey guys, Im an old member, but Im back in the Volvo game. I bought a V70R with a bad engine, and I need a replacement. From what I've read I know that the 2.4 T5 engine from a 05-09 S60 T5 or a 05-07 V70 T5 would be the best plug and play choice. However Im looking for one and losing my patience.

Have you called Erie Vo-vo, Strandberg Auto, and V&S auto dismantlers? If not, google them and call. I think they all warranty the motors and they all ship.

 

Im located in Canada, would probably cost me the price of a motor at a Junkyard just to ship an engine here.

 

If this is a money issue, why drive an expensive car as an R?

 

Hell, might as well go to Volvo and order it all brand new! It is an R after all which I have 0 intention of modding, so why no be stupid with my money and pay more for the engine than I paid the whole car!!

 

LOL

dude, best answer was given in the first reply by Khalil_y

every other post is obsolete....

 

They're over complicating things for OP.

¯\_(ツ)_/¯

I don't understand why people are saying you have to swap it out in the future. You're not going for power upgrades on it. It'll be fine as long as you put premium fuel in it and not romp on it in very hot weather.

Exactly, if you're doing all that you might as well shim it. If it's shimmed, you can mash on it all day and it'll take it. Good luck!

There's a bunch of 2.4 T motors on ebay for 600-700 each. Some include free shipping.
