Evo tuners i need help i am still not satisfied with so called "hp" of my car , i decided to go for a turbo upgrade to around 500 to 560 bhp help me decide please on which kit to go for i have listed below the major mods done to the car so far, which i will not need in the kit, i hope not so i will not end up with same parts again.

Motech ecu,
JUN 264/264 cams and cam gears,
High tension replacement belt,
Metal Head Gasket 1.2,
ARP head studs,
Trust Big intercooler upgrade,
Buschur racing upper intercooler replacement pipe,
Hks racing suction kit,
Buschur racing mass air pipe,
Walbro 225 fuel pump,
Blitz SBC I-D III Boost controller,
Blitz turbo timer,
Blitz Nur spec R exhaust,
Fuel pressure regulator,
Hks down pipe,
Exedy single plate + flywheel.

I think thats it so what turbo kit do you think..........

 

buschur 500.

 

And get rid of that HKS down pipe. Get a full 3" all the way through. YOu may also want to look into what automotosports has to offer along with the ATP kits.

 

What kind of fuel (pump or race) will you be using? Do you go to the track? If so which kind of track, drag, road course, auto X, ect? Or is this a street driven car where quick spool up might be desired. Are you considering stand alone fuel management? You should answer these kinds of questions first, because they are important in figuring out the turbo that fits your needs.

 

ok its a 98 octane fuel, its to be used for weekend crusing, racing and drag.

 

Yeah, I'd have to say the AMS kit, RnR Kit, or the Buschur 580 kit.. If you want overkill, keep in mind that you'll have a bit of lag with any of these kits, but with the right gas and tuning, you should see the power gains your looking for.. Your definitely going to need other upgrades to increase air flow.. maybe some head work too..

Oh, and the other post that suggested engine management.. He's running a Motec standalone.. Likely he's already ditched the MAF sensor for Speed Density..
