i would not suggest spending that cash. there are far more viable options.
the bump inside the GTX/R heads was introduced to improve spool time & combustion A major benifit when in vacum still.
due to the flow design & the tumble effect into the combustion chamber better fuel atomization & a more complete combustion were achieved.
the FE3 is always a very easy & effective option as well. you need not open the motor for the power levels you would see otherwise with a GTR.
in short to diss the GTR motor.
the rods are behind today's technology & reciprocating mass is not a good thing.
forged rods can now be had for under $300 which are lighter & far stronger.
the VJ23 turbo- non rebuildable CHRA cartridge.- also lagging behind the times with turbo technology.
evo turbo's are proven to provide better all around power/spool-characteristics/ response vs a VJ23.
I.E. there are better turbo options.
that leaves you with the intake manifold/valves.
i believe the 2nd generation BP (NA) intake manifold has a more equal tuned intake plenum then the 1st generation. & comes close to matching that of the GTR. combine that with VICS & you retain/improve low end while improving top end over a GTR manifold.
sodium filled valves-(awesome technology- great for shedding heat)
^ this was added to assess burned out stock exhaust valves which under extremes tend to let go in the BP.
SS valves are now available options as well as more expensive alternatives if you have the wallet.
so again. you decide
