So I'm ready to upgrade my turbo and I'm having a hell of a time trying to decide between and 18T and k24, skipping over 19T because of it's bad reputation.
I would REALLY like having the larger turbo that I can make 300ish WHP , without it being maxed out and blowing hot air. I can get a k24 with low mileage for under $500 so cost is pretty equal. Also I'm figuring the larger exhaust side should slow the spool time down making it a little safer, but some have said it spools even faster? So I have a couple questions for people that have installed a K24 on their non RN stock bottom end engines.

(Setup would be same as what's in my sig only new turbo, ARD tune, MBC in parallel to protect against spikes, wideband, and probably a FMIC.)



1.Has anybody here actually bent their stock rods with a k24? I've seen lots of speculation but I can't find a post from anyone saying it's happened to them.
2. What parts exactly are needed to install a k24? I know new oil and coolant lines, but are the s60r parts a direct bolt in? Does anything need to be custom made?
3. Is a k24 on a stock-bottom ended daily driver even a reasonable idea?


Sorry if i'm beating a dead horse here, I'm just really having trouble deciding and I dont want to pull the trigger if it's a bad idea.

Thanks!

i bent 2 rods with a little 16t..

Is almost all about the tune, you chose already to ad as safety the MBC and is a good start. Explain to Lucky (ARD) well your set-up and you will be fine. Others can cime in and say they opinion/ experience or story. I am going in the same direction K24.

I had my Precision Turbo, K24 and a 18T all sittin beside each other and the K24 made the 18T look small. Bottom line is the 18T is a Turbo that you can beat on and it takes it. The K24 is a good modern turbo that also has ETT. But... it isnt as tough as the Mitsu Turbos. BUT.. its going to get you 300whp for sure, has wicked spool, and you can get them fora good price. I actually sold a fresh rebuilt K24 for $600.

And on ANY Volvo turbo, just wait till the car gets to 3K before slamin them when chipped. Loading up a chipped stock motor at 2500rpm - max boost is never really a great idea. Also, its always better to stay on top of the turbo... as in rollin the pwr in vs just slamin it. I use that more than anywhere on the track especially.

why does 19T have a bad reputation...whats wrong with them?

[URO_S60]

^ Hard to control boost a lot of people have trouble preventing spikes and what not.

[JHEIII874T5M]

K24.

18T is just a glorified 16T and hardly at that.

[Fake-R]

I'd go K24 or 19T. With the right tune, your motor will last.

I've been running a 19T for a little over two years now, stock bottom end. I was using an iPd tune, but switched to Lucky's tune. AFR's are great, boost response is perfect, and no issues thus far.

[98t5M]

Thanks everyone! K24 it is.

So what do I need as far as plumbing?

Also, are stock white injectors sufficient? Lucky says they are but I just want as much input as possible.

Cuz If I need to pick up a set of jolly green giants that's kind of a deal breaker.

I'll have a set of greens available with less than 15000 miles on them. Just pm me if you're interested

[Fake-R]

Whites are just fine. Greens are overkill IMO. Been using whites for quite some time and still run a bit rich at WOT.

The first upgrade to consider in the fuel system would be the injectors, which stock are 315cc/min as I recall. A general rule of thumb on our engines with stock fuel pressure is that for each cc/min of injector size, you can achieve about 1 bhp. So with 315cc/min injectors you can achieve about 315 bhp, or 260-280 whp. There are Bosch-made Volvo injectors which are a direct replacement for the 850's stock orange top injectors. The 70-series T5 cars in 1998 received white injectors which flow roughly 350cc/min. In 1999, all 70 series T5 cars received blue 395cc injectors, which were original equipment on those models for quite a few years. In 2000, the V70R AWD received green 468cc/min injectors, which resurfaced again in 2004 when the R AWD V70 and S60 were introduced. A quick and easy way to up effective injector flow is to put in a Dodge 4-bar fuel pressure regulator from a 2.2 liter turbo Dodge (from the late 80s, early 90s). Which gives an increase in flow over our 3 bar.

Given the information here is correct, then shoot for the injector that will suit your power range.

Can anyone confirm this info? I mean it was written about 8 years ago lol.

If Lucky says his tune with whites will work then Im sure it will.

[Johann]

If you go K24 with whites, which is OK, I would personally opt for an 18T install.
Easier install, near similar power. Better known territory.

A good boost controller and good control over your right foot will help as well. My super60 15g outflows a 19t and I was beating the snot out of the car every day with no issues and no worries at 230k something miles.

[550]

I enjoy my K24. Ran whites with it for a long time. Now running greens because the price was right.

I think you will enjoy it. Keep the wastegate not too crazy because this turbo SPOOLS quickly. I can't stress that enough.

[rbodor3]

running 19t for about 50k miles and still going strong. the mitsu turbos are far more dependable then those kkk's

I keep seeing people say this... but I haven't had one fail on me except for my own neglect... and I beat it badly.

Rbodor3, I see in your sig that you are running 19T with 2001 2.4 LPT, is it with stock internals and how is it holding up? I'm planning on a similar combo for a 2000 V70 R.
