My new turbo...Is it worth it???

[DrFtKiNg180sx]

Well after searching for the right turbo for me I heard I can use a turbo out of any Volvo from a junkyard....So this is what I got.

now my problem is, Does anyone make a manifold for this? What kind of turbo is this and would it be worth the trouble to put it on my Sohc? O yea, this will be used as a daily driver

[fiznat]

Looks like a pretty teensy turbo. What model/year did you get it out of? I doubt it would be good for anything beyond very low boost.

[DrFtKiNg180sx]

I wasnt planning on a lot of boost anyways but I got it out of a 740, not too sure about the year but Im guessing 1990?

[scarboroughdub]

that looks to be a .42 comp side and a .48 turbine side standard shaft t3.

its a good turbo to build from you can add a bigger turbine housing and change the compressor wheel and housing and make a decent turbo out of it for the KA but in its present shape its too small for a KA unless your running small boost.

if its a .60 comp then disregard this statement but i dont remember volvo turbos being .60 comps.

[Craving4Boost]

the compressor is .52AR.......if you look under the wheel of the comp. there is a little square that says it.

[scarboroughdub]

^^^^ good eye i wasnt even looking

either way its soo small for the KA on both the turbine and comp side to make any repectable power but either way you can use it and upgrade in the future as it is a t3 flange.

[Craving4Boost]

yeah drftking, hope this is more of a budget set up. i see your from socal, as am i, so let me know if you need help. i know my profile says san francisco but i live in ucsd now

[DrFtKiNg180sx]

I was planning on using the JGS manifold cause it has the T3 inlet pattern like you guys said my turbo had, but when I saw the manifold it looks like it wont fit cause if you look at the bottom of my turbo its has circular indent on it. Can I still use this manifold or would I have to get it machined down for it to work. Thanks guys for all your help..

[DrFtKiNg180sx]

O yea, this is a low budget set up so Im not planning on major horsepower either, so I guess Ill just stick with the turbo till I get used it.

[Craving4Boost]

yes it still works because as you can see the bolts on the turbo housing are in a square shape so dont worry about the circular part. but since you mentioned that, you should get that ported out for more flow.

[Kenrik]

I have the same turbo i'm planning on getting 200hp or so out of it . it's a budget setup to give my car some more spunk.

I don't know what you paid but I got mine for $75

[Nismo_Freak]

Thats a KKK flange, not a T3.

[scarboroughdub]

whatever you wanna call it but the bolt holes line up perfectly to the t3 flange.

Actually, I'm pretty sure it's a Volvo-specific flange. I know many Swedish Brick enthusiasts manage to get a turbo with a standard T3 flange to fit on their weird manifolds.

I was just reading a bit about that turbo on a Volvo forum, and apparently a T3 .52a/r is fairly rare.

Who knows where you can find a compressor map for it. Maybe on a Volvo forum, maybe nowhere. At any rate, I do know that the Volvo engine it came off of was a fairly low compression 2.4L motor.

I gotta get me one of those funny Swedish turbo cars some day. They look fun.

No, thats a typical KKK exhaust housing, and it will leak horribly if you use it with a T3 flange because the gasket will be extruding into the housing, which will dissentegrate and strike the turbine.

I would suggest selling that turbo for a Garrett one, or ordering a KKK flange to use with a log manifold. The latter route would allow you to use the larger K26 #6 and K26 #8 which are typical turbos on Porsche 944's. The #8 being the larger exhaust side variant found on the Turbo S models.

Volvo used several different makers for their turbos throughout the years.

[DrFtKiNg180sx]

would I be able to machine the turbo flange down so it gets rid of the circle indentation and make it flush with a T3 manifold.orMaybe Ill sell it. Make me an offer, any takers? haha

[BadMojo]

Hmmm, my mistake. I didn't think Volvo used any KKK turbos on their older cars (I know they use 'em now). I knew they used Mitsu and Garrett turbos on the 700-series, but I didn't think that flange looked like a KKK.

As for using the KKK flange, it would just be cheaper to stick with a T3, wouldn't it? I would imagine that plain old T3 turbos are much cheaper and plentiful than a K26. What cars typically use KKK turbos these days? Audi, Porsche and Volvo?

[DrFtKiNg180sx]

**** thanks for all the info guys, but now I dont know what to do now I think im just going to sell it and wait for the right turbo for me?

first 60 bucks takes it..

It's not that bad a turbo what are your power goals? that should be good upto 250hp Also I think you can machine the flange to make it work, I was looking at mine with that same flange today and it's only a 1/4th of an inch that needs to be taken off.

Hmmm, its good for 250hp, another good reason to keep it. Where would I be able to get it machined down?

[Nismo_Freak]

Why don't you just buy a KKK flange and build yourself a log style exhaust manifold?

Save yourself the trouble, AND you can upgrade to larger Porsche KKK turbos at a later date if you so choose.

OR

Make a simple plate flange, with the T3 bolt pattern.



Fit's both styles, and just run the K26 flange gasket.

[pr240sx]

I was using a turbo just like that8psi full stock engine and 370cc injectorsQuite fast (did not dyno it)Was a 42 compressor 48 exhaust, was boosting at 2500 rpms strong up to redline.As for the flange, you have 2 options, expand the manifold falge to seal the little humps or machine the flage down to the grove.that turbo is cheap, easy available for a startup boost proyect.

[wild_maxx]

so did you use that turbo on a t3 flange or a kkk flange on your manifold? cause i have a t3 flange on my manifold and the turbo i got from you, does not seal to the t3 flange.

[pr240sx]

My JGS manifold flange (T3, T4) was big enough to cover the humps. No need to touch the housing.Also, try a Volvo turbo gasket. It have a small asbestos ring that covers the identation.Glad you have receive it.

[ghostchild316]

My first turbo was out of a 760.had the same flange also.I just took it to a machine shop and had it machined completely flat for 25 bucks.Walla I had a turbo that bolted to any T3 flange.I just drilled out the threads since the flange on my manifold was already threaded.

[naed240sx]

Ok sorry for the threadjack...

This is an unrelated question, but it at least applies to turbos. My friend just bought a bb garret turbo (I believe a gt30r), for his vr6 jetta. He swapped out the turbine housing for a larger one to adjust the properties of the turbo. Notice how the turbine in that turbo is very flush with the housing? The blades look to be only around 2 millimeters away from the housing at the tips. Well with the new housing bolted on his turbo, the turbine looks very small compared to the bore of the housing. Will this affect the turbo's ability to create boost? I saw it, and it looks like it will not spool nearly as well, but then again I know next to nothing about turbos.

[wild_maxx]

the gap kinda look like this? I was told not to run the turbo like that cause it will hinder performance.

[cesar240sx]

hi ,i am new to this forum, i have the same set up on my 93/ka24det.i did shave the flange and seals good,and i left the outlet the same, the exhaust shop found me 3 bolts flange for the down pipe its perfect

[naed240sx]

Yeah it looks very similar to that. He seems to think it won't matter, but taking physics into account, I think that the turbine should fit closer to the housing.

[K240]

That will definitely hinder performance. If i am thinking correctly, your friend that owns the vr6 will have to swap out the wheel to a bigger one.
