Dyno Graph Of Bnr 32 With Gt2560s In

[DVSGOD]

I got an r 33 GTR with a built motor and same turbos and im pushing 366 kw at all fours on 22 psi and pump fuel. My car makes 308 kw at 5600 rpm id post the dyno sheet but dont know how

What cams are you running GTR97 ?

On a more advanced engine e.g Fully rebuilt , cams/head work and tune the lagg can be taken care of through playing with cam timing , while still not loosing any of the mid range top end punch these puppies deliver.Just take it to a tuner who knows the fine tuning insides and outs of the RB26 and you will be very rewarded.Should be able to see full boost 22 -24 psi at 4500 rpm or just under but they will start pulling hard much lower than this so are still a very streetable turbo set up.

Alot of the gtr forums I visit from around the world rate these huffers above 2530s for there response and big delivery of power in the top end.

On a fairly stock engine Id put a gtss or the 2860R -7 turbo upgrade ahead of these unless of course you are taking it further down the track,these are purfect for a hard tuned street machine.

On a fully worked engine these turbs are good for 380 - 410 awkws

Just my opinion though.

Exactly my thoughts there, ive got a full engine rebuild in mind for the near future and im hoping to achieve just what u mentioned.

There 260 Tomei Pon Cams with adjustable cam gears. The turbos are out of puff but its good for street use.

Just my opinion though.

Have a compare & contrast between the compressor maps for the -5 & the -7. Given the small difference in size & the marked difference in efficiencies why would you choose the -7? Admittedly at 30#'s airflow on the -5's you will be looking at a 600+hp engine, but this isn't off the planet surely?
