Hey everybody, I've lurked for a long time but this is my first post.

Shout out to to RSPI for answering many of my questions before they were asked in the forums and helping me wrench on stuff with his Youtube tutorials, great contributor to the community.

After reading the "Modding your 2.3L FWD Turbo Volvo 850, 70-series" post which floats around on a couple different forums, it seems I have the 15G turbo with the conical outlet flange on my '95 850 Turbo.

I recently found a 2004 v70r parts car on craigslist here: Volvo V70R part out

I'm almost positive this has the angled outlet flange and (hopefully?) a 19T turbo. I'm wondering if it would bolt right on to my 1995 850 Turbo since 19Ts are supposedly easier to install than the 20 on the 2000 v70r. I want to make sure it is a feasible swap before I get too involved.

If a swap is possible, what (if anything) would need to be adjusted to compensate for a bigger turbo? I plan on using the angled outlet flange if I can since I know it has a tad more breathing room. I'm sure a 3" pipe from the turbo back would be better than my stock 2.25 but I won't be replacing my exhaust anytime soon (I hope).

Thanks for your help.

 

Update: I've been told it is probably a K24 turbo with an angled outlet flange in the '04 v70r. Apparently the K24 has different oil and coolant ports than the turbo in my 95' 850 T5, but with extra effort I could make it work. However, if I wanted to use the angled flange I would need a different down pipe than the current stock down pipe on my 850's conical flange. Also I was told that new 19t & 20t drop in turbos are available for the P80 platform cars (850/70 series '99 and back?). One of those turbos seems like an easier option compared to working around the K24 oil and coolant porting issue. Thanks to rspi for the above info. Does anyone have any suggestions or experience regarding turbo preference? I would consider doing a little extra work for the K24 if it would be a better turbo in the long run. When choosing my turbo, I'll be biased towards all purpose and longevity vs. highest performance; though it would be nice to know if a K24 or 20t is stronger.

 

Look at it this way. The turbos you are looking at (minus the K24) are all TD04 Mitsubishi's. this means that the CHRA cartridge (the middle section) is the same for all TD04 turbos. What does this mean? The exhause housing will accept all TD04's. You can take the 15G out and direct bolt in the 19T into the 15G exhaust housing. You dont have to change the down pipe and can keep it all stock. You will lose out on some HP though. When the time is right you can swap out the conical for the angled and add a down pipe.

BUT, you dont just change out a 15G to a 19T and take off down the road. Your engine management needs to be updated. You need a tune to support the 19T and if your doing that you might as well up the injector size to add more fuel. The stock ECU has a fuel cut off right before 15psi so no matter what turbo you put on there if you hit that boost the car will fall on its face, you must get a tune to remove the fuel cut off.

 

That is all very good info, thanks a lot. I am leaning towards a 19T because my engine will most likely remain stock and I want to be gentle on it (180k). Do you think it would be worth it to pull the green R injectors and angled flange from the V70R, or would my time and money be better spent trying to buy bigger injectors online? I do not have much background with tuning, any specific tunes you would avoid or recommend from your experience?

 

The 19T has been nick named the rod bender. Green injectors are a nice fit. Get the tune done professionally so you dont have any issues.

 

I guess I'll be looking for the 18T, some green injectors, and a mild tune done right. Nice YT vids by the way.

 

I loved the 18T. Smooth daily driver and crazy when you want it.

 

That sounds like exactly what I want.

Do old injectors hold up pretty well? I've heard something about replacing the seals if you buy them used. Feels like I should just buy them new, I found a pack of 5 Bosch green giant injectors part# 0280155968 brand new for $115 free shipping. Not sure if they fit. Worth it? or should I get used ones for 50-60?

 

I dont know where you found them but years back I bought some knock off on Aliexpress and I could not even get the car to start. So be wise with what you buy.

 

I've enjoyed reading this discussion, as I am in the midst of preparing an B5234T9 out of a 2004 C70 to go in my 97 854R that I picked up as a project car. I'm doing a lot of reading, and taking my time as this will be my first complete engine swap, and to do it right on a 250k mile car means I need to replace a LOT of things - and that gets expensive. I can't dump a couple grand into the car all at once, but a few hundred a month over the winter to get ready is doable.

One thing I wanted to comment, after reading this thread is, that injector price is too good to be true. Those are surely some sort of knock off injectors and I just wouldn't go that route. You probably aren't going to get quality injectors with the spray or flow that you would if you had the real deal.

You can buy a new set of Greens from a guy on Facebook named Nick Gregory Bernstein for about $250 from my reading - or get a decent set of OEM used ones for about $100.

My project car has a 240k mile B5234T5 that the previous owner slapped a 16T on, and went out and bent a rod. You don't have to have a 19T to bend rods But I bet you could do it a lot quicker with a 19T.

I'm planning on porting a stock 850 intake to match the ports on the RN block, either going with a japanifold or something a little more exotic, a downpipe of some sort, and a good tune. The 850R engine is quick enough for my taste, and it's not that I need more, but rather that I feel if I'm going to the level of work to swap it all out, I should put a little more work and $$ into it on the front end.

I think I'm even gonna put those Bilsteins I bought from boxpin on it

 

After further review, the aforementioned new $115 injectors are aftermarket. The manufacturer threw Bosch into the name because they fit the same as a Bosch FI would. I think Bosch might be the OEM for green injectors.

The set from the '04 V70R should have at least 4 OEM injectors; the guy said it looked as if the fifth injector was a replacement so its OEM status is questionable.

I'm not sure how relevant it is, but I would be driving 1.5 - 2 hours round trip for the used injectors if I decided they were my best option. $250 for new ones seems like a lot, but I'm not as familiar as I'd like to be with injector pricing.

I'm jealous of your Bilsteins, still gradually going through my basic stuff before I shell out for good suspension components. My springs and struts aren't too terrible yet. Upper strut braces, all 4 shock mounts, subframe bushings, and a poly motor mount are next on my to do list at this point.

 

Woohoo! Fast lane talk. lol

UNYVolvo, thanks for the kind words.

I would suggest that you map a end plan for the performance of your 850 T5. What power do you want to end up with or what 1/4 mile time do you want to hit.

The '99 V70R has the 18T and the '00 V70R has the 19T. As Boxpin stated, you will need a custom tune for your projected mods. I currently have a 16T on my '95 850 T-5R. I only swapped it out because my 15G had 293,000 miles on it and I had a 3" downpipe to install. So I installed the 16T, straight flange, 3" downpipe and replaced the under sized cat. Now my car has the boost and power that it likely had new.

The biggest mistake I think people make is tossing on a manual boost controller and tinkering with their wastegate actuator. If you install upgrades, and get a custom tune, you should have more fun with it. A good tune will not let the boost kick in to soon, which can bend a rod quicker that you can finish your Wow expression.

I recently had some serious questions about tuning and Boxpin is who I went to, no one else. From what I know, he's been through most of this tuning stuff one step at a time and he's down to earth enough to shoot straight.

 

rspi, thanks for the kind words.

I dont want anyone thinking I can tune, I cant, but I have been through just about every TD04 turbo and have run IPD, ARD and Beust Tuning tunes so I can answer questions.
