Car Just Got Tunes Rb20det

[ashr32]

I’d just like to say a big thanks to Paul at Chasers in Melbourne for his hard work in getting 215kw out of my rb20 r32. He actually got a run of 230kw but the injectors couldn’t cope.

Quick specs

Unopened rb20det with unknown Km’s

· Hks25/30

· yellow jacket coil packs

· STANDARD Injectors

· Power FC

· Walbro fuel pump

· Greddy cooler

· Hks adjustable actuator 16psi

· Arc airbox

· 3” full exhaust

I tried the gtr injectors with a resistor pack but it was nothing but dramas so went back to stock and put a FPR on at 85psi

Feel of the car

Fantastic full boost at 3800rpm, second gear is all wheel spin and the noise is unbelievable.

If you don’t believe my ask the VE SS driver last night who got the shock of his life when a 20 year old skyline passed him on low boost like he was nothing.

Absolute magic.

HAHA sounds like your really enjoying yourself Post up your results in the Dyno Results thread if you already havent Whats your idea of low boost?

lucky bugger!

Wheel spin with that power and sort of response, time for some decent street tyres & wider than stock rims, then thin thing will be way more enjoyable

Good work, I like the mods, nice and neat! Just get those injectors sorted, 85psi base pressure on the reg = f**king band if anything goes wrong.

MORE FUEL!!!! MORE BOOST!!!!

Yeh well maybe some like the wheel spin but you will definately have much more useable power with the wider wheels, better suspension etc

Not that im one to talk I still have stock suspension and 9inch wide wheels and Im hoping to make 360kw.

Yeah hear is a longer list of parts currently on the car

lmgt2 rays 9" 17" wheels

235 federal tires

whiteline rear swaybar

isc coilovers

isc cam gears

But at 4000rpm in second gear the car just takes off. i can't even look at my gauges or hand controller, its hectic.

Will be ordering 550cc injectors and raising the boost to 19ish psi

yeh the adrenalin just kicks in and you just cant concentrate. All I can usually think is "f**k yeh!!"

I have the same turbo on an RB20 but with GTR injectors and its great. 210kw at 16psi and only about 65-70% injector duty. My timing had to be held back massively as well, only running 8 degrees on the 'full load' area points on the map as above that it knocks(carbon hot spots or something, its an 185,000k engine). Still feels good, felt very fast when running proper timing as well. Out of interest are you able to look at your ignition map and let me know what kind of timing your running on the high load, high RPM points?

Cheers,

Adrian

yeah no problems at all, the injectors hit 90% duty cycle at full boost from memory. but I'll get the details for you later

245/40 R17's will fit mint on a 9" wheel

245/40 R17's will fit mint on a 9" wheel

yeah the wheels came with 225's on the front and 255 on the rear but with 15% tread so i just put the federal 995 on.

guys what do you think my 1/4 mile would be at this stage? 13's ?

[JonnoHR31]

just keep an eye on your injector duty on cold night/mornings

[bloodsword27]

should hit 13's easy. good stuff on the progress too

[boostn0199]

got to love the feeling of shifting gears with the wheels frying up ahhaha makes me excited for how my 33 will be this week after the tune after a long wait of building it up shame I wont be able to drive it for another 6months. Definatily get the 555cc injectors there really good

[SimonR32]

if you set up suspension and tyres right, 12's should be no problems
