any ideas?

Ok so assuming you are running 235/40/17 Dulnop D01Js, and shifting at 7,500rpm

RB20

1st - 3.321 , 60.98km/h

2nd - 1.902 , 106.4km/h

3rd - 1.308 , 154.8km/h

4th - 1.000 , 202.5km/h

5th - 0.759 , 266.8km/h

Final drive - 4.363

RB25

1st - 3.214 , 66.8km/h

2nd - 1.925 , 111.6km/h

3rd - 1.302 , 165.0km/h

4th - 1.000 , 214.9km/h

5th - 0.752 , 285.81km/h

Final drive - 4.11

Obviously if you are running a higher profile tyre, or larger diam wheel then those km/h could be a bti higher, or vice versa for lower profiles or smaller diam tyres.

And even though technically your car may be geared to pull 7,500rpm in top gear and a certain speed, i highly doubt that std engines have enough hp to overcome the drag etc at those speeds to max out the revs in 5th gear

Fark, my 32 gets 170 - 175 in 3rd, then about another 5 - 10k's in 4th before limiter, after that who knows!! will need to take the limiter out and get a better speedo!

Not sure about standard but with 240rwkw my car pulls very hard in 5th and I have no doubt it would hit 7000rpm in 5th with ease.

I never went that fast when it was stock though so no idea. It still pulled pretty well in 5th though.

I think I calculted it out based on 3000rpm at 110km/h that 5th gear at 7000rpm should see 256 km/h

im pretty sure if you calculated it out you would get 270ish. i bet when your cars at 2000 rpm your doin 70 and when your at4000 rpms your doin 150. you have an increase of 40kph per 1000 rpm increase

The stock engine does have enough grunt to pull top rpm in factory trim. :D

Looks to me like htere are different gear ratios going around between these cars, which ties in with a converstion I was having this weekend.

4th tops out at 120mph / 7000rpm for me, others I know of get at least another 10mph on top of that.

      The stock one will outperform any aftermarket standard position exhaust manifold. If you don't believe me, do a back to back test (same turbo, same boost, same timing) and you'll be super surprised.

      Any recommendations on a decent replacement manifold that doesnt break the bank or require additional mods for the stock turbo setup? I figure if I'm going to pull the manifold off anyway to fix the studs might as well replace it.

      So I checked the turbo out today. Very minimum play at all just enough for the oil to take up when it's running. I did find an exhaust leak at the manifold. 1 stud all the way in the front is missing and the one all the way in the back is broken off. Front has visible signs of an exhaust leak. I'll fix that soon but that's not my problem still.  I also found that the nipple coming off the turbo had the hose capped off and a hose ran from the j-pipe by the bov going to the wastegate. I removed that hose and capped that nipple and put the turbo nipple hose back on the wastegate.  There was a ton of oil residue all through the charge side of the intercooler piping going to the throttle bodg. I'm thinking that's from the pcv. Doesn't seem to be coming from the turbo that was all clean on the pipes side.  Haven't had a chance to check fuel pressure yet, haven't had time been having to pull a lot of doubles at work. I did pick up some carb cleaner to clean the iacv but wanted to make sure I had a fresh gasket in case the old one rips when I pull it off.  I'm waiting on a MAF that was supposed to be here today but delayed to Monday. Have a double Monday and Friday and work all of next weekend so going to try to find some time in the middle of the week to try that out. Did about a 10m trip around the block today and towards the end the issues were coming back. Fingers crossed on this MAF but if not just going to throw a fuel pressure gauge in and see where I'm at.  Did notice today that I can definitely hear the injectors pulsing. Very audible clicking coming from them. Assuming that's normal? Should also mean CAS is functioning somewhat properly. After it warmed up when I started it the intermittent misfires came in again. Did start doing that before it was fully warmed up.

      This morning I carefully reinstalled the manifold and started looking at a couple of things I need to do.  Heat wrap arrived sometime today so I popped into the shed with the missus dishwashing gloves and started wrapping the first half of the dump and the screamer/plumb back.  Once I do the second half I'll be able to final fit the turbo and exhaust up.  Also pulled the harness out today and started terminating it at the ECU end. A connector is done, just need to run the remaining wires that arent in the harness - 12v, gnd and couple I/O
