KKR 280 turbo upgrade on the 6A13TT
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 against the KKR 280
A pair of these should get you close to 280kw atw Each turbo is rated at 180-280hp.
Cost is AU$500 each in Australia trade prices. Come with a 6 month 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, the engine mount is a little close here, its was modified to give more space..
And here's the rear, not much room as you can see.
Further along the line, the rear turbo again.
Front one
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 550cc, I'm using Sard 650cc)
A new ECU to handle the upcoming injector control such as haltech E11
Oh and a boost controller.
(did I miss anything?)
EDIT:
After a few months the work is finally completed. See the attached dyno sheet, the car made 260kw max at all 4 wheels, but with a fuel rail mod, it could potenially make closer to 275-280kw.
Power and Torque, all figures are KW at the wheels
Showing boost pressure relative to RPM.
