    What's better with a turbo....longer or shorter gears? and why? GS-R vs. ITR gearbox.

    Llonger = better (generally speaking). It really only comes into play (in my opinon) on larger turbos though. For a small turbo w/ quick spool, stick w/ what you got. And cost/availability is why the GSR gears are chosen over the ITR.

    For drag racing....with all things being equal... itr 1-3 and gsr 4th.

    Look at chuck seitsinger...he runs B16/ITR 1-3 and GSR 4th and runs low 8's.

    you also want to look at what rpm you will fall into when u upshift and if its within ur powerband.

    i would say stock GSR final drive.

    Gear ShiftRPM Speed @ 11000 RPM
    1st N/A 59.9
    2nd 6471 101.8
    3rd 7874 142.2
    4th 8363 187.0
    5th 8372 245.7
    RPM in top gear at 70 mph: 3134

    Thats what he usually traps in 4th so stock gsr final drive

    Chuck won it ALL against mofos w/ the XTRAC ($10,000 tranny) too. But he was rebuilding after EVERY event. When I was stationed in Oklahoma City (97 - 00) He was a nobody... he worked at the Honda dealership in the parts department!! LOL
