Really quick one -

HOw fast would I be going, doing 5,500rpm in 5th gear? (top gear)

All of the drive train is standard bar the clutch.

I can't reply till this afternoon, but I will be checking email replies.

Thanks guys

About 230/235

I have hit 251 at 6300rpm

nismo speedo and greddy full auto timer to verify they are very accurate

easiest way to work out what speed it would be is drive along in 5th at 2750 rpm. double the speed that you are doing and that is what speed you would be doing at 5500rpm.

i had a 180sx and it had pretty much the same ratios as the skyline, but had 400rpm extra to redline. it would hit the speed limiter at about 7200rpm in 4th which was 190kmh on the clock, and it hit it at about 5000 in 5th

just went out for a spin and according to my speedo and tacho i was doing 90kmh at 2500 rpm, so that means 5500rpm would be 200kmh (approx 35-36km/h per 1000rpm). but if someone with an accurate pfc or something similar could do the same thing and get an accurate km/h per 1000rpm would make all the calculations easy.

      Wow the colour matched hard top completely transforms the car. Are there any nice front lip options for the car or is that off the table?

      Generally yes but for some reason I've been ruthless this time around!  I might even need to do another tip run after the way I've finally been able to hit the delete button on shit I've stepped over, stepped around and tripped over for the past 10 years!

      I just quote the Rolling Stones. Paint it black.

      It just depends if you're like me with a high level of OCD for doing something like hardlines, and highly critical of the little things, and then bugger all patience to get it how my brain pictures it

      More than happy with the colour match Talking to the painter he recommended to give the top a few weeks for the paint to 100% cure prior to sealing it with the ceramic stuff Also, because why not..... I have a fancy pants Fluidampr harmonic balancer on order, the 2.5 engine uses the OEM 2.0 balancer off the old motor as the 2.5 balancer is a larger unit and doesn't fit clearance wise, which, because the two engines have different harmonics, isn't optimal, the OEM balancer does the job, but as the gear driven balancer in the bottom end is removed to fit a RWD application there is slightly more vibration, the Fluidampr helps with the harmonics that the gear driven balancer once took care of,  basically makes life easier on the oil pump and bearings when thrashing it around Hopefully the weather gets better soon because I'm keen for some cruising around, and currently, with the winds and storms we are getting, the amount of detritus being blown around from trees on the road isn't something I want to be driving around in
