heres my ratio's. @4000rpm

1st.. 45kph

2nd.. 70kph

3rd.. 95kph

its quite tall to start with. but you can bang thruthem pretty quick and pull alot of ground on people :)

As a reference,

Trust 6 speed dog box @4000rpm:

1st - 42.0

2nd - 60.2

3rd - 77.4

4th - 99.0

PPG 6 speed dog box is:

1st - 36.4

2nd - 53.3

3rd - 74.8

4th - 97.2

PPG 5 speed dog box is:

1st - 39.1

2nd - 62.6

3rd - 82.7

Yeah it's definitely not a dog box... :P

Well im looking at some gearbox options...its good to see some referrances to the speeds of the PPG gear ratios/speeds up..anyone has the OS giken gear ratios/speeds referrances?

Still trying to work out which gearset yours is Dave. Roughly your ratios are 2.6, 1.7, 1.3

I've already done it on an excel file and also have RPM v Gear ratios for max speeds.

Stock ratios@4000rpm, speeds are:

1st - 36.2kph

2nd - 60.9kph

3rd - 89.6kph

OS Giken@4,000rpm, speeds are:

1st - 43.3

2nd - 68.5

3rd - 94.4

Route 6 ratios@4,000rpm, speeds are:

1st - 44.8

2nd - 68.0

3rd - 93.8

    • Aye, everything is being touched and all the parts that are responsible for the oiling issues are also fixed. (Crank collar, billet prp oil pump, head return to sump, yada yada yada)  Everything used is of reputable brands like greddy, prp etc. My tuner did mention we’d keep the torque on the “lower” side.   glad to read that my engine won’t blow up on me lmao 
    • It's a fuel pump. EFI, high pressure, but specs otherwise unknown. A bodge job.
    • 800 engine horsies is fine. Will need all the obvious upgrades. Rods, pistons, oil pump, big sump, sump breathing mods. Build for revs because revs are power with less stress on the bottom end compared to boost. Keep the torque down in the midrange, either by limiting boost or timing.  
    • Hiya guys,    i’m currently in the process of getting my rb26 built. everything is being replaced with better/upgraded parts or oem when that’s good enough (which isn’t alot lol). someone earlier mentioned to me that i’ll be screwed cause the iron block can’t take 800hp (to the engine, not wheels) which is what it’s being built for.  what do you guys think about this, am I cooked or na? The guy building the engine will also do the mapping as he is “the guru of old nissan engines” here in Belgium. I know the mapping makes a huge deal so i’m not concerned about that.    I honestly he’s talking shit cause he’s that kinda guy but a second opinion never hurt anyone! cheers in advance! 🫶🏻
    • I'm seeing torque specs all over the place for the OUTER tie rod, but none for the INNER tie rod, where it connects to the steering rack. Even in videos, people are just tightening em up as much as they can with a wrench and that's it. Anything tightened down without torque makes me nervous. Anyone know what the spec is for it?
