I know the question has been asked several times what the 2.5T turbo could be direct bolt on upgraded to. The discussions usually die off with no solid answer except this should work...and it seems like there has been no real application of this

Sooo....has anyone ever ventured into this territory and ACTUALLY upgraded to a 16T/other turbo or uprated the 14T stock turbo?

If I ever got the time/money to get this far it would be good info to know if this upgrade has been done successfully on a 2.5T, or if a S60 T5/K24 motor swap would be easier/less time comsuming. I know the one guy in Sweden (i think) with the Evolve kit, swapped in a T5 motor for his 2.4 NA motor.

Yea definitely 19T, you could probably push close to if not more than 300hp with that. Definitely more than 300 tq though.

AND MORE THAN 300 BENT RODS! Get a K24 off of a junked R, injectors, downpipe and a super good tune from MTE.

I've def thought of that too...makes me feel like a wannabe R though instead of a tuned Vanilla S60. It would be a good setup though.

I'm guessing that with the higher compression engine the 2.5T has...I would need to run lower boost on a K24 than on an R.

isn't an R just a tuned vanilla S60?

People have run high boost (22psi) on stock LPT blocks (ifnt420) and made pretty good numbers like 270 awhp (300+ at crank) with a tune by Marco at MTE. It's all in the tune. these are his mods :VST REV, Aquamist, UR pulley, ITG, TME 3" DP & Cat-Back, R Exhaust Mani, Green 465cc, KKK K24, SvR FMIC. you already have the R manifold and catback

Is there a certain year of S60 that runs the R manifold? I was pretty sure I saw that the early years ran a lame manifold then they all switched to the R manifold on the Turbo model.

05+ all manifolds are the same.

That's what I thought I saw...

Re: (stealthS60AWD)

Definately if your even going to spend the money on it go with Borg Werner products. The K24 is a much better turbo than any mitsu style Td04 even the 19t. In a perfect world you could cough up the coin for a K26/27 hybrid and a strong bottom end (rods), green tops, walbro 255, front mount ic, good tune youd have pretty reliable power. Thats the setup id go for if i had the loot if you care haha http://********************/smile/emthup.gif

ive been reasearching this for some time now and i really want to do some sort of turbo upgrade but people here dont exactly help on where you can get these things and really get into it. please someone send me a link about whatever rods are necasary to do a 2.5t turbo upgrade and what turbos would work best and also comparasons on them. please help so we can do this

if you just throw on a 19t w/o ( or any turbo with a much larger compressor wheel) a tune you run the risk of developing too much boost too early. i just swapped over a 16t onto my 2.4t w/o a tune and it works fine without it, however i would not go any larger without getting a custom map or you could be looking for a new motor

Are you sure about that?

2005+ P2 T5's shared the R's manifold (along w/ strengthened internals - and turbo?). I'm pretty darned sure that the other 'vanilla' P2's don't.

low pressure turbos, t5s and Rs all started to get R manifolds in 2004. they really shouldnt even be called R manifolds.. but its the best/simplest name i guess you could say.

Call up Erie vovo, and they will tell you the same.

a 16t would be a very safe upgrade i would say.. there are quite a few people that do this more than successfully on 850s/s70s. I would go ahead and splurge for the k24 and run it at 10-12 lbs the intake temps would be MUCH lower than a 16t at 16-18 psi. You would also have a higher ceiling for mods. The determining factor however may be the availability of tunes.

do 2.5t awds? have the same transmission at Rs?

Mine has the 5spd GT...M55...98% sure on that. Think thats the same 5spd GT the 04?05 Rs had. Could be wrong but I thought it was the same 5spd.

interesting..

also the newer cars control boost a little bit better than the 850/x70s do.. and to be honest, i havent heard of anyone with a newer car bending rods yet.

I know they are kinda weak, but still, its not an epidemic like it was on 850s(have heard of bending rods on stock turbos), but i do know i have seen a ~320 whp dyno from a guy with a fwd v70t5... stock block.

But they do crack blocks all the time

You sire are correct

01-04 tranny / are the same tranny minus some internal items that make the 03-04 stronger .

but all the connections are all the same

he dyno'd 180whp, im sure he'd be stoked with 10-12psi on a k24

Agreed. I am stuck with three scenarios:
1) Get a DP and tune on the 14t...see if that is good enough power for me
2) Source K24 and Injectors from an R, w/ DP, and Tune
3) 16T upgrade or go for the meatier 2.3 T5 engine swap

Thanks for the advice and opinions seems like 1 and 2 are the cheapest and easiest but 3 might be sweet

How many miles have you put on this 16T? Still on stock tune?

Has or would anyone else really suggest this swap especially with stock tune?

why don't you do a 16T with a tune, and DP? It'd be so much dough to swap in a 2.3 motor or to put in a k24.....Do a 16T with DP, tune, and that will be plenty of power. Honestly, if you wanted more
power you should just buy an R or a t5...

16T w/ DP and tune prob sounds good. I'm not looking for crazy power but maybe more along the lines of a T5/T5 tuned power. Going to a 16T I would probably need the bigger OTE pipe too, right?

I did not get into this car initially with tuning in mind at all. T5 would be nice but FWD...meh not sure if i can go back to FWD from AWD (especially in New England)...and going to an R, I think I might have a better chance in my AWD S60 and avoiding some of the more well known R problems. Yes angle gear stuff can be a problem on mine as well, but it seems on the newer and non R, looks like less failures. And I have one thing R owners dont have KW Coilovers

. Plus it would cost me too much to get out of this car unfortunatelly...I'm in this one for the long haul
