Guys,

Got my car tuned today after having -9 turbos fit in on stock engine with power FC, exhaust and bleed valve....

was a bit disappointed by getting only 286kW.

It did 265kW before that....only 21kW difference after changing stock turbos to -9?

Does that figure sounds right?? just a bit curious....

Its on a GTR33, stock motor...

Help me guys, after spending that money, i was aiming for at least 300kW....

Do you think there is a problem or should i have supporting mods? If i need supporting mods, what minor mods can i have??

thanks guys :)

most obvious question, how much boost?

were those figures on the same dyno, same settings

The previous figures was on the same dyno as well....

I was thinking of getting an opinion for another tuner....

i was been told that if i had smaller wheels, i could get upto 300kW ???

Sounds right, for safe tune.

Changing timing to bit aggressive top end may get you 300rwkw. I did this after wanting 300rwkw and told tuner to make me happy so he did it.

EBC - Electronic Boost Controller. If you've got heavy duty Garrett or HKS actuators, EBC may not be required. You've also got bleed valve so was told it's fine.

I do have bleed valve, so i may not need EBC....i have the standard HKS actuators....

i was thinking of fuel pump and changing the injectors....

OR

get it fully retuned by someone else as well.......

At this point, I'd talk to few tuners and see what they say about your setup and your power goal, and go from there.

Changing fuel pump and injectors wouldn't yield more power BUT will give you extra fuel to feed into motor so you can raise the boost to achieve 300rwkw (I achieved 302rwkw at 90-96% injector duty - not recommended), you'll need Nismo AFM for better resolution (again, talk to tuner they should explain you better).

      Here is a recipe. Sonic blocks till you get one that has a good enough bore. Get a torque plate and block brace, use your choice of fasteners (arp ect) bolt the thing together empty, half fill it and let it cure. Release it when it has, go to a REPUTABLE RB Builder and get the thing line bored/honed and cylinder honed to size, then wash. Once its all clean and dandy, wash and blow it out again. Then again.  Assemble said engine to your desired clearances with oil control mods, gasket to suit desired CR/Squish ect. Attach your extended sump with proper trap door oil baffles and head drain plumbed to sump with a SUMP BREATHER SYSTEM. Build your front diff with a decent LSD, rebuild your transfer case with a few extra plates, more than likely replace your tailshaft centre bearing and tighten up the rear diff. Tune to minimise excessive midrange cylinder pressure (timing unless you like to split bores and rebuild engines) Enjoy your engine, but hate the fact you are now destroying engine mounts, gearboxes, gearbox mounts, diff output flanges and driveshafts, diff mounts, tailshafts and front CV's.   Disclaimer.... Ive never done any of the aforementioned stuff.......

      440s will support well over 400HP on petrol, which is a decent place to be for an RB20. 230+rwkW. Will be a safer bet for idle/low load. 550s would be nice for the extra headroom. I've made the same decision with mine (Neo25). 1000s are probably too big for the Nistuned ECU, so I have some smaller ones.

      Did tie rods. Steering now not "springing" back.

      Appreciate everything guys. I did go ahead and get an alignment... most of my complains are solved. Car is not perfect, but it's good enough. If I notice uneven tire wear or anything I'll just take everything back to stock.  Thanks again!

      They still have not shipped the 550cc injectors as they weren't in stock, so in theory I could ask to get the 440cc ones instead, if those work better in my scenario. They're the same price so really shouldn't be an issue. Unfortunately I am not so knowledgeable in most parts of tuning so I wasn't sure what's best to choose between the two. 440cc ones are the lowest they have (not in stock, but available to buy nonetheless).
