just to start, I did search, and didn't find what I need.

I am picking up the K27 turbo, I'm putting it on a s5 turbo II motor, and its going in my vert Engine will be huge streetport or half bridge to help spool the turbo a little quicker.

What I need to know is, if I want to run 13lbs boost on the street, and about 20 on the track, what injectors should I get, primaries and secondaries. I'm looking for about 450hp street and 500+ with the boost cranked up.

Also, is there a manifold that bolts to the turbo II's block, that will hold the k27, and let it fit in the engine bay without work? or am I gonna have to get a machine shop to make me one, so far its looking like machine shop.

Also, what rpm will boost probably kick in? I am going to keep the car "streetable" but since I'm in south Mississippi, I don't have emissions, or noise ordinances so I can run nearly straight exhaust.

Please remember that there are many different Triple K turbos. However, I am going to assume you are talking about the blitz, Triple K MOJ3470.

Check the little blue tab on the compressor side to see what model you have exactly.

now the other stuff. At 13PSI with this turbo I get 360 to the rear wheel's. At 15PSI close to to 400. I do not believe you will be able to efficently hit 500 to the wheels with this turbo.

It is a small turbo, and you will not need a bridge to spool it. With a regular streetport you can expect spool to hit at about 2500RPM.

for fuel considerations check out www.maxcooper.com
he has a nice fuel calculator.

Hope this helps

holy ****. are those numbers accurate? 2500rpm spool, 360@13psi??

venomrx7

check the title!! HKS KKK K27

I do know one thing, this is no small turbo, it is the one on the right, the one on the left is a to4, for comparison

venomrx7

bump

anyone? anything?

Yes the turbo is physically big. Doesn't mean jack ****. Look at the inlet for the T4, and the KKK. Notice anything?

By the way. A T4 is a turbo series, not actual turbo spec. Big difference there.

Read that blue label that is on the KKK turbo. It will give you the specs. Do some research on those specs to find out what you have.

As I said. I have this turbo on my car. So, I know to an extent, what it can do. I have Dyno verified numbers for this turbo on my car. 360RWHP at 13PSI. Approx. 400RWHP at 15PSI.

Post the numbers that are on the blue metal label of the turbo.

One more thing. Are you sure it is an HKS?

$150FC

yes, i was wondering if HKS even sold KKK turbos.

I don't know a whole lot about KKK turbos, though. is a K27 a specific turbo or is a family of turbos, like saying T04?

do you have any dyno charts, jesuscookies? not calling BS, heh, just interested in the powerband.

GarageBoy

HKS uses garett only. Unless it actually says so on the blue label. Ask SR Motorsports.

The SR Motorsports 'custom spec' turbo's aren't really true KKK's. Not that they aren't great turbo's, but they are really Holset.

$150FC, yes the K27 is a family of turbos, like the T4. Here is a sheet I grabbed off of the web, that gives a little bit of info.

http://home.att.ne.jp/omega/hipogtr/...t3/TboComp.jpg

The kkk turbo is a german made turbo that is used on Porsche's and Audi's. There construction is very nice.

Blitz makes a kit around this turbo for the RX 7. Basically, rebadging the k27 turbo with the Blitz name. My guess is that this is what venomrx7 has. However, I could be wrong. In any event, he could solve the mystery by making that little blue label on his turbo readable.

One thing to note, all Blitz flanges, snails, wastegates, etc.... use proprietary flange designs. This can be a pain in the *** if you just have the turbo. You will have to have someone custom make you the flanges you need.

And finally ,yes I do have a dyno chart. I can scan it if you want , but I do not think it will prove anything. If I remember correctly, it just shows the line, and the power. Trust me though, I layed down 358.6RWHP at 13PSI. I had all the accompying bolts on as well. I will see if I can find it, and post.

$150FC

well i said i believed you (why lie?) but i just wanted to see it. if it's a big deal, don't worry about it.

also, is that to say that Blitz flanges/etc are different than the OEM KKK flanges?

Jesuscookies

iTrader: (1)

Not a big deal. I just have to get my lazy *** out to the garage to dig it up. The powerband is beautiful by the way

No the Blitz flanges are the same as KKK flanges. Sorry I did not explain that so well. KKK flanges are big offset circles.

Here is the Dyno graph.

Had to shrink it to get it on here, but you get the picture.

I know that t04 is a family and not the actual turbo, but the only difference between the different to4's is the turbine so either way, the housing serves for good comparison.

venomrx7

heh, true, this isn't that one, I don't think. but even if it was, it wouldin't matter

both the holsten and the kkk are made by borg warner and are basically the same.

Your turbo is a straight KKK turbo (no rebadging). It was used on the 80 to 81 4.5L BMW 745I.

If you search the net you should be able to find some more specs on it. Good luck with your swap

venomrx7

is this bigger or smaller than yours? Is it capable of 500 ponies?

venomrx7

oh, and the reason that the inlet on eht to4 looks similar is because there is a flange on it, the actual turbine is much smaller, look close.

Jesuscookies

iTrader: (1)

I do not think it will. Do some research to find out the specs on the turbo. Then compare those specs to what is being used on the 500RWHP cars. E.G. SPL51, T88, T78.

venomrx7

well, check the other k27 thread, the guy, Ernie, pulled a 520hp dyno run with this same turbo, I found that, so I guess it is possible

uhhh... no.

there are a lot more differences in to4's then the turbine. The to4 in that picture is a to4b btw. one of the smallest to4's.

Are you sure ErnieT was running this exact turbo? I thought he was running a SR motorsports holset?

88fc3sw/HX83

Jesuscookies is right, ErnieT was using a SR "stageII" turbo.

venomrx7

yea, he was, just noticed that. damn, well.....

thats still not much different, both turbos are borg warner made, and have very similar chaeracteristics.

and i thought that the to4 was the housing and then the letter following was to designate what turbine it has?
