Blitz KKK Turbo Kit

[FattyMcBaggins]

Hey everybody. I've been planning/budgeting my SR build up, and I'm strongly considering getting the Blitz/KKK Turbo kit. They offer to different turbos, one rated for 450hp and the other rated for 500. I'm not quite as worried about max power as I am spool up. I want somewhere between 425-500hp, but I'd like some reasonable spool. Does anybody have any compressor maps? dyno charts? experience in general with this kit? Thanks!

[HardcorePS13]

What do you consider a decent spool?

KKK series turbochargers typically get changed out for Garretts, just some food for thought.

[FattyMcBaggins]

I don't know what would be considered "acceptable" spool for the power numbers I'm shooting for. I'd like to have full boost around 3500, but I don't know if that's way off or something. As far as the KKK turbo, I figured if it's good enough for OEM Porsche, than it can't be too bad. I may swap turbos somewhere down the road, but for now it will suffice. I like the convenience of a turbo kit, because I'm terrible about forgetting to order certain parts. And since my car is a daily driver, downtime means time off of work, which means less cash. less cash= Anybody have experience with these kits?

[Blown240sx]

Arnt the Triple Ks used in the VWs also?

[spider_slayer]

400rwhp AND fast spool most likely isn't gonna happen unless you have some insane setup.

edit: jsut saw that you consider 3500 accetable. just shop around for something ball bearing and maxs out at 400.

[VitaminT]

A guy was selling a used kit a while back. Think he sold it for like $2200 or something.

I don't know that you will get over 400whp with sub 4k spool times. I think the guy with the kit did make like 376 or 390whp with the smaller kit (k6?) though.

Note that most HP numbers quoted by Garrett or in this case KKK/Blitz are crank HP not whp.

[Dori Dori]

KKK turbos...meh. If you want 400whp w/ quick spool, get any of the good top mount manifolds (full race, love fab, one fab, peak boost, ect) and a t3 flanged GT2871r (GT 3" discharge, not the old style t3) w/ a .63 a/r. You'll also be able to use the extra money on fuel, tune, and maybe some cams and an intake mani.

OEM Porsche doesn't mean much. Porsche is a low budget builder, but they will tend to spend money where it matters. Unfortunately the turbochargers were good in the 80's but turbos like the K27 and K26 are no match for a modern day equivalent. They will make power, but you will find greater efficiency with a Garrett turbocharger.

I think if you find yourself wondering if the lag will be suitable or not for you. Then you need to look at the 400whp number as your goal, and as Dori said go with a GT2871R in a .63.

Don't look past the fact that a larger hotside will open up the low end on the car. Not only that but peak boost is relative. Once the car produces boost you will be accelerating well enough for daily commuting. When you are out racing you rarely should be putting yourself at a point past the boost threashold even on a car where the turbo spools at 4000.

[FattyMcBaggins]

I'm willing to try putting together my own "kit", but I'd really like to pass the 400whp mark. 401whp is fine with me! Every site that's selling the GT2871R quotes around 360whp. I'd really like a little more than that. If I build my own kit, I will be using the Full Race top-mount manifold or using the Peakboost "top mount set up kit". Not sure if the Full Race is worth THAT much extra cash. Will that turbo reach the power goals I'm looking for. I'm hoping for just over 400whp. Sorry if I'm sucking with all the questions. I'm still learning all of this stuff. Also, if I go top mount, what other parts am I going to need? What will need to be fabricated/bought? A complete list of what I'll need would be AMAZINGLY great. Thanks guys

EDIT: motor will be completely built. Crower rods, CP Pistons, Ferrea valvetrain. Cam selection will depend on which turbo I decide on. i've heard mention of GT30 being popular for higher horsepower applications? I'm just trying to get as much info as possible. Thanks

The compressor of a GT2871r is good to over 400whp, that's been proven. Don't confuse .64 a/r t2's with .63 a/r t3's. It should get you to the 400whp mark but not much more.

If you want over 400whp with the fastest possible spool, a 3071r .63 would be your best bet. A 30r with the same turbine will take you over 450whp. Here's a dyno of a 30r @16psi (full race).

[spider_slayer]

does the turbo max out at 16psi? cause 450 to the fly i believe is something like 380 to the wheels.

No, the 71 wheel will push alot of pressure at a moderate flow rate. I would honestly go with a GT3071R in a .63, it has better wheel matching.

[Dori Dori]

No way. A 30r compressor map can be found @ turbobygarrett.com if you want to see it. That's whp btw.

[HardcorePS13]

Same 56 trim wheel used for alot of the GT28 - 30 series turbos.

That's what I have coming. I can't wait.

[HardcorePS13]

It's a sweet turbo.

If I decide to build my engine I will be going for a GT3582R or something around that level. However it will be interesting trying to keep the turbo out of the surge line once it starts to build pressure.

[FattyMcBaggins]

Man...it's hard to decide whether the extra power is worth the loss in spool between the 2871R and the 3071R. Damn you decisions! Since it will be daily driven, I think I'm going to get the Enjuku "Peakboost setup kit" with the Gt2871R. I think that spool will make it a little more fun on the streets. If worst comes to worse, I can always upgrade turbos. Is the Peakboost manifold a good choice? Or should I go with the Full Race?

BTW, you guys are awesome. Thanks for all of the help. That 30R looks like it'd throw you into the seat once it spooled up!

EDIT: Any dyno sheets of the Gt2871R in the .63 trim? I'd like to compare power bands a bit

[Dori Dori]

Unfortunately no dynos of the .63 gt2871r or gt3071r .63. When my car's done, I'll post one up.

As for the manifolds, the peak boost is equal length, lifetime warranty, ss, shorter runners, nice merge collector, and cheap (comparatively speaking). It's what I have and could have afforded the full race. I just think its too expensive (although it is the best). You're really paying for the exotic materials used when you get a full race.

[FattyMcBaggins]

Hm...I'll be arguing with myself for awhile over which I'd like more, the quicker spool or more peak power. That extra power of that 3071R WOULD be fun, but it seems like it'd feel like FOREVER waiting for it to get there. It will be a daily driver though. The nice power band of the 2871R will rock. I'll probably pick that one. Now, what else will I need for all of this stuff to work together correctly?Peakboost top mount manifoldGarrett GT2871R .63 with a T3 flangePeakboost 3" downpipepeakboost dumptubeTIAL 38mm wastegate700cc or 850cc injectorsZ32 MAFstandalone or Enthalpy tuneIs that it?

Spool up is about 400 RPM between the two choices.

I would go with the GT3071R, it's a better turbo and honestly the lag is something you will grow accustomed to. You will notice it is not that bad to drive on.

I would go stainless lines on the turbo.

[FattyMcBaggins]

oh, we're only lookin at a 400rpm difference?. I was under the impression it would be about a 1000 rpm difference. Hell, I'm going for the gt3071r in .63 trim then. No doubt about it. You guys rock. who's a good supplier for stainless turbo lines?

Difference in lag will be minimal. Might even be less than the guesstimated 400. They have the same turbines and better matched compressors.

Don't waste your money on a peakboost downpipe. For the price, you can easily have a custom downpipe made and have enough extra money to get a ss turbo line kit.

700cc injectors will suffice.

As for the tuning...I'm going enthalpy tune. Standalones can be a PITA although the bells and whistles are nice.

[HardcorePS13]

The turbines are not the same. The GT3071R has an 84 trim or 90 trim wheel with a 56.8mm major diameter. The difference in turbine flow is notable.

[FattyMcBaggins]

Yeah, I was planning on going with an enthalpy tune. Then driving to Florida a few months later and having him dyno tune it, really dial it in. The Peakboost downpipe comes with their little kit on Enjuku, so I'll most likely just keep it instead of dealing with the hassle of having one fabricated. We'll see when the time comes though. Thanks for all of the info everybody! NICO ROCKS!

[Dori Dori]

That downpipe is over $400. That's excessive although it is nice...nice flex section and no need to have a test pipe (downpipe extends to the catback exhaust).

Hmph, could have sworn that Enthalpy told me the 4 bolt gt housing on either turbo shares the same turbine. I can't find the info on the Garrett page either...they list the same turbine for both housings w/ certain a/r's and no listing for the GT housing w/ the .63 a/r (unless I'm looking in the worng spot).

[FattyMcBaggins]

I didn't know that it goes all the way to the exhaust. I was planning on running a high flow cat, but I guess not! Is it true that running with out the cat makes your exhaust smell super nasty?

Trace flow rates at 1.5 PR, notice the difference?

GT2871R - 53.8mm / 76 Trim

GT3071R - 56.5mm / 84 - 90 Trim

* Turbine stage is outline interchangeable with GT2554R (471171-3), GT2560R (466541-1), GT2860RS (739548-1)

The actual GT3071R runs a larger turbine. The one sold on ATPTurbo.com and other sites lists the turbocharger with the smaller (albeit optional) turbine wheel which is the same as the GT2871R.

Depends... typically that smell is from catless cars that have poor running conditions or are running on cheap fuels. You can smell a difference between exhaust that has been scrubbed by a cat.
