KKR 280 turbo upgrade on the 6A13TT

[Madhav]

I posted this thread on ozvr4, but I thought it would be nice to share it.

If you're like me, once you get to the 15psi or so limit of our standard turbos, you may want to upgrade. The standards are tiny and will get you max 180-220kw atw, depending on tuning, transmission type and a few other things.



Here's a photo of one of the standard turbos




A pair of these should get you to 300kw atw (we will find out soon). They can flow 280hp each according to their website. They have 360 degree thrust bearing, so not quite as good as garretts, but they come with a warranty (that includes drift applications) and are a lot lot cheaper.


Cost is from US$200 each on ebay, AU$500-700 each in Australia. Come with a 1 year warranty. Popular with Aussie drift boys.



They are not suited for our manifolds (4 bolt), but with an adapter plate fit fine. No need to change manifold. here's one fitted to the front.


And here's the rear, not much room as you can see.




Mods needed to fit KKR 280s are as follows:
Manifold adapter plates
Oil filter relocated
Front engine mount modified (see photo above)
Thermo fan slightly modified, needs a little trimming.
Rear firewall massaged a little
Custom dump pipes
Custom oil and water lines

Mods recommended before doing the turbos:
Brakes upgraded (either new pads and rotors or brembos)
Trans cooler or better clutch if manual
Custom 3" exhaust and front pipe
New plugs and leads
Better BOV
Decent panel filter and battery in the boot for more space
Decent fuel pump (walbro)
Custom intercooler piping and new core (at least 600 X 210 X 76, you could do this at the same time as fitting the turbos to save a few bucks)
Bigger injectors (at least 450cc, I'm using nipondenso, fit straight in)
A new ECU to handle the upcoming injector control
Oh and a boost controller.

(did I miss anything?)

Now as you can see they definitely fit, but how much power they can actually make on our engines is yet to be discovered. As is when they hit full boost, whether the auto can take the power. Ohh and the other thing is whether the engine internals can safely handle 300kw atw....

Stay tuned.

EDIT: Can't get any of my pics showing on here? Dunno what has changed? Gonna have to post links instead... if anyone can edit it and fix it feel free? got the attached thumbnails working.

And it comes with Gym membership?


This is really interesting! Are you fabbing your own manifolds, then?

[Madhav]

Lol... no it's just to give u an idea of size mate.

No like I said it fits with a adaptor plate, u can keep the standard manifolds.

Should be good for 550hp at the flywheel, or around 400hp atw.

Hi Mad,

This is very interesting. I have been looking at these turbos too, but wasn't sure of their actual dimensions as they're very rare in the UK - looks like they fit then!

I am the same as you, I have made all the supporting mods including the intercooler, uprated ECU to Autronic and fuel pump etc - I am just deciding on the turbo route.

Would you be interested in selling an additional pair of adapter plates and turbo elbows? Did you get a pattern made when they were fabricated? Anything you can share to enable others to do the same would be great.

Many thanks,

Mart.

Yeah they fit, it took the engineer in Australia a bit of thought.... but he managed it, hats off to him, without him I'd be nowhere.

I would recommend waiting until I get them up and running first, i.e. see at what RPM they spool up and how much power they actually make etc, and we can all see the dyno charts. Also I'd let u know a total cost of all the hidden extras... If from there u still like what u see, then of course I'd be more than happy to offer it to everyone, but yeah.... first let me be the guinea pig, and also see if my engine and transmission survives.

[Caveman]

Good man!

When do you realistically expect to have it finished?

Mart.

[Madhav]

I reckon I'll be driving it in no less than a week, hopefully by Friday afternoon.. by then we'll be able to see the spool up time.

On the 19th I'm booked in for the ECU and injector installation, from there Dave at RPW will turn up the boost and go nuts with the tuning.

[Caveman]

This is VERY exciting, I wait with baited breath!

Please keep us posted on progress.

Good luck

Mart.

get amsoil ATF in there and a transmission cooler for starters! (thats if you haven't already )

[Oblivion]

I'll be keeping an eye on this for sure!

[scott.mohekey]

VERY interesting! I wonder if there is an importer of these in NZ?

Cool! I actually know the guy that owns/runs JDM Performance.

Discounts??

[scott.mohekey]

Lol, I could ask him next time I see him. He's given me discounts on some things in the past. I don't see him often though, and I don't think I have his number at the moment.

[Goku]

Hmmm..... I was told about these turbo's about a year ago, but didn't have the cash to look too much into it....

If smohekey here can get us some sort of discount... might be an option

[Madhav]

Yeah mate have done 2 x ATF flushes, last one was with amsoil. Cooler is installed already also, from here there's not much more I can do.

[Madhav]

That price is pretty high? I got mine for AU$500 each from a licensed distributor, so I know for sure the warranty is good and the turbos are genuine...

[scott.mohekey]

Does it make a difference that that price is for the 330 rather than the 280?

[Madhav]

Well turbo wise, the 330 flows more hp, but has a slower spool up time, so I'd go for the 280 personally unless you're looking for crazy hp... price wise I think they are pretty similar for all the 'kompact' series, i.e. the 280, 300, 330 or 280.
