POSSIBILITY OF STANDARD INJECTOR???

Still standard injector!??

Standard 444cc/min 2.55bar of f/p


May be you can guess??
What this graph for??

How much power can factory RB26 injector handle???........We know standard injector is just enough for boost up level, also airflow meter is using 80% of their capacity.
In this case, we changed fuel pump to NISMO and try(this is the point!)........... engine has GT-ss class turbo and tomei poncam.
At 1.18 to 1.2bar, around 7500~8000rev injector and airflow meters are reach to almost 100%, however air flow ratio is in safe zone................ made over 300kw at wheel.
And try 1.3 bar......................up to 6500 rev A/F ratio in safe zone but.....no more than that...start to lean out..
Made over 310kw at 4 wheel........................but this is only try, better change to bigger one soon.(**_**)' Turn the boost down please.......................

EVOLUTION AND ACHIVEMENT OF 260RS

New look!!!!

TO4Z Hairdryer. try 2bar this time!!

Good progress !!

When I saw this car at first time in 2005, engine mod was just basic. Started from 280 kw at wheel with steel shaft turbo, Tomei poncam, piston, power Fc etc...................And next time, engine's got TO4 z turbo, still running with two air flowmeter power fc, 360kw at wheel.........And next time, change exhaust system....370kw,..........And next time change computer to F-con V pro, take two air flow meter out.........over 400kw at four wheel............... use for a while ............. And engine screamed(cracked block).......

And this time.........everything is new internal and block motor with old set up(To4z), how much more than before?? Result..........................464kw at four wheel!!.....over500kw at rear wheel ! 2bar of boost with pump gas!??(Yes clanked B**** up) But turbo is running out of puff (*_*)'

Evolution still continue....

So ............What's next???

R34GTR BOOST UP!!

Looks familiar??


Standard!! Airbox too!!?


Power & Torque


Boost (little bit too much)??

How much power can R34GTR make from just boost up? The car has air filter replacement, front pipe, cat back exhaust with catalytic converter, spark plugs, and power FC.(use 4th gear today, 5th is too high for this engine I think)

Start tune with no boost controller,...........No power!! And boost up to 0.9, 1.0, 1.1, 1.2,1.3.....................smell??....something??....................Oh clutch is starting to slip.
So, result is just over 250kw at wheel 1.3bar of boost(drop to 1.18bar),..........
240kw at 1.15 bar.... is best power to use on the street I recon. Not too bad at all!!!
