OK. All speeds and ratios are based off using a 265/35X18 tyre, an RPM limit of 8000 RPM and the use of 4.11 diff gears.

OS GIKEN Sequential - the stock ratios given when ordering one it looks like

1st 2.609 = 90 km/h
2nd 1.934 = 121 km/h
3rd 1.521 = 154 km/h
4th 1.210 = 194 km/h
5th 1.000 = 234 km/h (stock ratio)
6th 0.852 = 275 km/h - 3158 RPM at 110 km/h

I personally like this option. Its a tad shorter in 1st and still can cruise on the freeway without spinning its head off

1st 2.890 = 81 km/h

2nd 1.891 = 124 km/h

3rd 1.468 = 160 km/h

4th 1.174 = 200 km./h

5th 1.000 = 234 km/h (stock ratio)

6th 0.757 = 310 km/h (stock ratio) - 2806 RPM at 110 km/h

Stock ratios on a 32/33 are;

1st = 75 km/h

2nd = 120 km/h

3rd = 180 km/h

4th = 234 km/h (stock ratio)

5th = 310 km/h (stock ratio)

OS GiKEN 5 speed is

1st = 87 km/h

2nd = 138 km/h

3rd = 190 km/h

4th = 234 km/h (stock ratio)

5th = 310 km/h (or 290 km/h if you get the OS giken 5th option IIRC)

PPG sets:

5 Speed (1-4 helical dog set)

1st = 89 km/h

2nd = 143 km/h (farken mega tall)

3rd = 189 km/h

4th = 234 km/h (stock ratio)

5th = 310 km/h (stock ratio)

For the sake of it ill throw in the Getrag PPG 6 speed. These are mad! This is with 3.545 diff ratios.

1st = 85 km/h

2nd = 124 km/h

3rd = 174 km/h

4th = 226 km/h

5th = 272 km/h

6 th = 327 km/h - 2653 RPM at 110 km/h

Argh, number crunching. Time for a beer :D

Don't have to use the R3C clutch...other options out there.

Good comparison, Paul. (Similar to what I had/have on a spreadsheet).

I also like the option 2 OS88 ratios. However, the "UK-spec" ratios are even better:

2.9966 (92kph)

2.05 0 (114kph)

1.521 (135kph)

1.210 (183kph)

1.000 (229kph)

0.784 (278kph)

:cheers:

I can't remember the number of times I have hit 300 or had the space to do that

I'll never get there, but it's the cruising rpm. We still drive to Vic for DECA's. I ain't sitting in the car for 7 hours at 3500 rpm.

pussy...

in all fairness, when I removed my clutch I was informed that the thrust bearing was undersized which made it very hard to drive...pretty much every mechanic and tuner that drove my car stalled it, was that bad.

thrust bearing or not, I put it equal to that dog shit JB whatever he wants to call it.

Junk. Shu boy, shu!

    • Depending on how long the car sat it is very possible for injectors to be stuck open or closed, I'd get them cleaned and flow tested. Other than that, obviously when the loom changes and the car doesn't start any more....the loom is suspect so some tracing / comparing may be required
    • Harness is for a s1 Rb25det, and it is engine and lower harness.  the old harness had broken off plugs and was in very rough condition/exposed wires and splices etc. it is not able to be put back on the car, I could visually inspect to see if they had rewired any pins on the ecu plug. The fuel pump definitly isn’t turning off it’s an external pump and very loud you can hear it. Will look at the other harness tonight, am also going to pull the fuel rail and watch the injectors spray, will update here with what I find. Pretty sure at this point it has to be something to do with injectors because car will fire up on starting fluid and cas is clicking the Injectors. Fuel pressure is steady 43psi 
    • Check the injectors flow evenly, and are actually flowing what you and the ECU think they should be flowing. If it's starting up on starter fluid, you have a fuel issue. Is it possible under cranking your fuel pump is turning off?   The harness you replaced, is that the whole engine harness? Do yourself a test, and drop the old harness on and plug it into the Z32 ECU. It's possible they've wired things different. From memory S1 to S2 is different in RB25 and you may have a wrong loom
    • I haven’t pulled the injectors to watch them spray yet but they are clicking from the cas and all of the spark plugs are wet with fuel. I’ve thought the cylinders were being flooded from the beginning and was hoping fuel pressure would fix it. Tonight I am going to pull the rail and watch the injectors spray. Don’t know how to test/diagnose if the plugs are firing in correct sequence but that should be a timing thing and as far as timing goes my car still has the half moon for the cas can only install it 1 way. And my mechanical timing is 100% correct I posted photos above. Confirmed with the balancer on and off.
