Why can't we bolt on 300hp? B5254T3 -> B5254T4

Why does nobody look at S60R parts? 300hp shouldn't be hard. The B5254T3 and B5254T4 are almost identical; both based on the B5254T2. Except the R puts out 300hp.

Open these two PDF's side by side:

http://www.volvoclub.org.uk/te...s.pdf

There were only a few differences that jumped out at me, maybe others can elaborate:

R: ME7.1
S: ME9.0

R: Forged crankshaft
S: Heavy crankshaft due to different motor mounts.

R: Con-rod bearings are lead-bronze
S: Con-rod bearings are copper-lead (i.e. no tin, different alloy)

R: Con-rod big end "cracked" cap
S: Con-rod big end "split" cap

R: 19 gear teeth on coolant pump (faster)
S: 21 gear teeth on coolant pump (slower)

R: Turbo 20% larger than B5254T3, maximum boost 1.1bar (16 psi)
S: Turbo-fold, obviously 20% smaller, maximum boost 0.7 bar (10 psi)

R: Manifold from XC90 - B5254T2
S: Turbo-fold is the manifold

R: Cooling fan has 13 blades and 7 speeds
S: Cooling fan has 7 blades and 6 speeds

R: Dual cat-back exhaust runs
S: Single 60mm exhaust pipe

R: Two intercoolers, one behind the AC condenser and one in front of the radiator in the lower bumper
S: One intercooler in the same place as the S60R intercooler

So, why can't I go to a scrapyard, find a R that's been rear-ended, and grab:
- Exhaust manifold
- Turbo
- Downpipe to cutup for parts

Then order from Volvo:
- R crankshaft
- R pistons
- R conrods
- R coolant pump

Then build/fabricate/buy:
- Better IC, like Evolve or Kyle's
- Mandrel bent intake piping
- 3" turbo-back exhaust

And finally tune to 300hp? It sounds like a lot, but unless I'm

it's under $5K for everything. What am I missing?

From my understanding it's a slightly different block.

I believe the S60R block is a little thicker in the walls and has the ability to go well into the 400hp range before you need to put sleeves in/other engine mods whereas ours could not handle the compression the S60R block could.

If someone can dispute this then please do as my information might not be 100% correct, just going off some convo's w/ Volvo Tech's understanding (and he may be wrong too!)

S60R Cracked sleeve, engine rebuild with B5254T3 block

My engine has been rebuild by swedish auto here in SA, and they gave me a 20 000km/1year warranty. They did however use the B5254T3 block.

Can anyone also correct me here? Are these blocks EXACTLY the same? the bore and stroke seems to be exact but what about the wall thickness, cooling channels etc? These guys wouldn't give me this warranty if they know the engine wont last with the power.

All the other items were replaced with NEW VOLVO parts like mains, big ends, rings, gasket (MLS, R's), etc.

Thanx

5K for that we could do a new turbo setup and put down 300 easy and have left over money to do wheels, tires , suspension ... and a couple other things ...

I've also heard people say this, but I've never seen evidence. Anybody know?

Okay, so what do you propose? I've yet to see a bolt-on turbo option for the S40. Except the S60R...

I'm not talking about one-off's. There's a few of us (myself included) who could order some steel, go out to the garage, and come out 8 hours later with a shiny new exhaust manifold. But that will leave the rest of everyone asking "can you build me one"?

I postulate that not everyone wants the ability to go past 300-350 hp that the R engine can *easily* handle, and that most of those everyones also can't build their own manifolds. If we can work out the kinks in an R conversion, not only can we legitimately use the badges, but we also open up the option to the masses.

Buy an ATP manifold and go nuts.

Sorry, I didn't include AWD.

The size of the turbo you can run and whether or not the turbo will interfere with the transfer case on the all-wheel-drive model is yet to be tested.

Where as the R and the S40 have the same exact AWD transmission (M66C)

Re: (theshadow27)

You are correct, but I would be more inclined to go with ATPs setup. They say our block is good for at least 400hp if not more, its all in the tune or course. The R block has some weaknesses, being hotspots, and thin walls in some places, especially between cylinders. Not sure what the B5254T3 block looks like in terms of cylinder spacing, but I would guess its the same, however the cooling paths are better. With the R components, you are still stuck with the limitations of the stock R turbo, which is not all that great either. If anything, it might be a good idea to go with the R crank, pistons, and forged rods from RSI

As the posts above state we now have a Turbo manifold ready to go!

So really things are coming along alot better for the S40 crew Finally but before we had everything we do now i would have agreed ... I think VERY soon there will be some kit finished and we will be running in the 300's easy. without spending 5k

I think you have a great idea but you are a little late in the game. which is ironic since upgrades are only just starting to get better for our cars.. I would of said last year this was a sweet idea... Now i still thinks its ok but for me ill stick with a turbo upgrade

That works with the T5 AWD M66?

Yeah thats the one, apparently Nautilus will be stocking this "bolt on" kit once the final R&D is complete. Been a long ass project though and still has some missing links.

Oh and the ATP turbo kit should work just fine, however, the downpipe is what will conflict with the bevel gear. Could opt out of the downpipe setup and use their manifold, I believe AJ had messaged them about it or something and they are willing to drop the price some.

I have been under the impression that the turbo manifold flanges are different between the R and S40 heads... need verification of this. Only one I know that would have side by side manifolds would be IPD but have never asked. The R turbo isnt enough of an upgrade from the S40 to make it worth while when an aftermarket kit could be built for roughly the same and make more power.

So far unfortunately no one has PROPERLY pushed the S40 engines so a peak power hasnt been established. I think ATP's statement regarding 400whp is doable is pretty solid. They have been in the industry for quite some time and their tuning is pretty solid so would trust their opinion.

Well, the car that ATP modded and dyno'd was pushing 340whp. I wonder why we can't just ask them if the car is still pushing that power/holding up well. They must know what the test car is up to these days, right?

Engine SWAP!
Image


Okay, now that I have that out of my system... the time that we've all been waiting for is approaching. I couldn't wrap my head around blowing my CPO warranty to do a turbo swap. December is the magic month where I can kiss my free parts goodbye (warranty is up), and say hello to the turbo swap. My plan is to let everyone chime in as to what the best combination from ATP would be for our car and that is what I'll do. The guys at powerchip owe me a custom dyno tune for my car, so the turbo swap map is what I'll use it for. That way, anyone who wants to do the set up will have another choice for a tune. Hopefully it helps everyone out who wants more power!

My S40 is no longer my DD, and therefore we can all go wild at my expense

I emailed ATP and got a quick response. Check this out:

Hi Rush,

One of the reliable engines we've ever come across.

450WHP almost 500 ft/lb of torque.

Only problem we've had is a clutch that can hold the power and we've
contracted a company to build a twindisc clutch to hold the power.
Meanwhile, the car runs around as a daily driver on about 400HP/400
ft/lb of torque with a spec stage 3+ clutch.

20K miles now and not even 1 single loose bolt.

Once the twindisc clutch is in along with a quaiffe lsd, we are going
to shoot for 600HP on the stock block.

Holy hell yes.

Re: (Revolve40)

Well then

I think it's moot at this point.

My only gripe with the ATP is the 90 degree before the turbo. The Nautilus looks like a much better design, but I have a feeling that the price will be higher than the cast one

Didn't heico put the S60R engine on the S40 Odin racecar?
It's feasible at least

Yes they did. However they had to make new engine mounts so the engine could sit back further in order to fit the smaller S40 engine bay.

Bolting a S60R turbo has been done before according to Lucky.
