ive been told by an engine importer that the 5 speed is weaker because its for NA and the innards of the trans are smaller to fit in the same basic housing as the 4 speed

and who knows what ratio 5th runs at?it may run at the same revs as a 4 speed at 100 kph therefore no gain in the 5 speed

probably not the exact same ratio, but it would be close. they usually the case in all cars. final ratio for top gear is usually the same because the cars have enough torque and get the best fuel economy with the gearing at a certain rev range

I imagine the "extra gear ratio" will slot between 3rd and 4th. As I feel there is quite a gap between 3rd and 4th gear in a conventional 4 speed auto box.

I thought all the automatic r33s got 4 speed gear box, but when I listen to my car, its voice drops 4 times after it lauches, I mean I can hear it changing gears four times after when it accelerates from the 1st gear, which means there should be 5 gears in it!! Is there really any 5 speed automatic gear box exist for r33? or my gear box is just wierd? or it changes 4 times just mean it's 4 speed?...

Can any expert give an answer...

Yes, there is a 5 speed auto.

From what I can establish, they were only fitted to 4 door N/A r33

      My thought is if you were just moving it forward and the upstream geometry remained the same, then no difference at all. But because the current one has the filter direct into the AFM inlet, you effectively have the best chance of a completely symmetric air flow profile upstream, and in, the AFM, whilst the aftermarket inlet thingo has a (small, to be sure) bend between the filter and the AFM. That would bias the flow to the outside of the bend (downstream of the bend) which might well reduce the size of the signal seen by the AFM, for the same total flow rate. Having said that: If you're proposing to make your inlet look like a hybrid of your existing one and the aftermarket one, such that there is no bend where the filter is clamped on... then I say it will be just fine. If there is going to be such a bend, then, if you can align the insertion of the AFM blade such that it is at right angles to the plane of the bend, then there is a better than even chance that the centreline velocity where the blade is will remain more or less the same, and the velocity will just be a little faster to the outside of that, and just a little slower to the inside. **This is not professional investment advice and you should consult a suitably qualified ouija board, tea leaves or the intestines of a goat for more accurate prognostication.

      Blue/grey smoke after idle

      By pacman_1219 · Posted

      Hi Tao, Thanks for your reply.  It's been a while and I managed to get the valve stem seals replaced with the head on the car.  Unfortunately this didn't solve my issue, the car still smokes a lot after idling (to be honest during idle you can see a bit of blue smoke from the exhaust), same after deceleration. I will try disconnecting the valve cover breathers, do I leave the PCV valve in? By engine oil drain pipe, do you mean the turbo oil drain?

      My guesstimate, with no real numbers to back it up, is it won't effect it greatly at all.its not a huge change in position, and I can't see the air flow changing from in turbulence that much based on distance, and what's in front of it. Johnny and Brad may have some more numbers to share from experience though.
