Rb26 Turbo Upgrade, All Dyno Results

[SiR_RB]

Forged rebuilt rb26

Precision 6266 t4 divided .84

GFB EX50 wastegate

Adaptronic

Greddy 264 cams

BC valve springs

2000cc injectors

Walbro e85 450lph pump

Plazmaman front mount

448kw @ 24.5psi - caltex e72

[just_racing]

Standard RB26

Twin RB25 afms

Ebay intercooler

3" pretty much straight through exhaust

6 Boost exhaust manifold

GT35R

Twin 044 pumps

880cc injectors

E85

Lightened flywheel

485hp @ 7300rpm

So the RB26 has just had a birthday! my aim was for a strong reliable motor with more response and extra power if possible without losing response.

Cams 264 10.0 Inlet, 272 10.0 Exhaust

40 thou over forged CP pistons and Eagle rods

Ported head with 1mm oversize Brian Crower valves

Supertech double 90lb springs

8.9:1 compression

adjustable cam gears (which have been set)

Externally everything is the same pretty much.

Green lines on the dyno sheet are last tune and the blue line was after the build.

Hi, I am starting to rebuild mine for response, in the Dyno charts, the BROWN is with the new PT6262 Turbo and Poncams B.260 9.15 and tune, 333.9 AWKW, BLUE is with the old T78 337.9 AWKW. Lost top power but low end is much better, good response

They said the car was getting modified for track and was a work in progress, I want a DD with grunt

1999 R34GTR

PT6262 turbo

HKS EVO 6 Boost Controller

Tomei poncams B 260 9.15

ATI balancer + damper

nitto h beam connecting rods

je/nitto forged pistons

nitto drag head gasket

ARP head stud/main stud kit

Head work

nitto high volume oil pump

9Lt sump conversion

Ni water pump

splifire pack

Exhaust mods,HKS dump pipe

Os Giken quad clutch

Nismo 2-way LSD

Having a stainless custom Exhaust system made for a more free flowing system, Walbro 460Lt fuel pump and Haltech Pro R34GTR ECU installed with Tune, hoping for more response and with the fuel upgrade can be tuned up for more overall power, but will give top end up for response.
