Nope, can't use 3rd because it will kick down to 2nd at low rpm and big throttle openings.

Aside from giving inconsistent readings, that's rather dangerous as well.

Auto's are nearly always done in 2nd gear for that reason.

It's an auto anyway, so there is no such thing as 1 to 1 in any gear.

The torque converter won't lock up under full power, so there is always "slip".

:O cheers :(

fair call. when I had an auto S14 years ago,I did my dyno runs with the shifter in D,with the OD off,and had a graph that went through both gears.

the S2 stags don't have this problem,as they can be put into the tiptronic mode,and do the whole run in 3rd,regardless of load,it won't kick down. that's how my 154kw atw graph above was done. in third,in tiptronic mode.

As i have stated previously in this thread i had my car dynoed today!

And well all i can say is i am very very happy with the outcome, i have got the print outs from the day which i will post up tommorow cause i dont have time right now and a pic from it.

Anyway it made 162 at all 4 wheels :) very very happy as i was only expecting around 115-120.

So im stoked

on stock boost? 7psi you made 162awkw?

with the same mods as you bar the sitc (which doesnt really do anything on its own anyway) and i had a fuel pump, i made 140awkw on 7psi and then 160awkw on 13psi.

BTW, the 040 is an easy fit into the stagea because of its craddle design, its a good pump to use in them.

Alex: i have the sitc but its not fitted, the only mods that were on the car yesterday when it was dynoed were: Full exhaust, FMIC and Hi-Flow.

The print outs said the car was on 13psi at peak power however i do not have a boost controller *confused*

As in, your sig says

1997 Stagea RS4

Mods: BOS SS Split Dump/Front Pipe, BOS SS High Flow Cat, Fujitsubo Cat Back, ARC Crossflow Cooler Kit, Z32 AFM, Apexi Panel Filter, Apexi SITC.

I dont see anywhere where it says TURBO UPGRADE...

Of all the mods I did, the turbo was the only one I really felt and you leaving it out made me doubt the 160awkw.

Putting a bigger exhaust on will raise the stock boost level due to a change in pressure or something like that...

On a stock S13 Silvia turbo I put a full turbo-back 3" exhaust on and the boost went from 6psi to 10.5psi.

On a stock S13 Silvia turbo I put a full turbo-back 3" exhaust on and the boost went from 6psi to 10.5psi.

My exhaust is 3" turbo back on both my cars, and both have the standard stock boost of 7/8psi.

Little surprised bout your results simon, l thought you may get more than that due to the turbo, as l've got a few less mods than u and got 150.4 on that dyno.

Only thing l can think is that the SAFC2 makes a big difference!!!

SAFC does make a big difference.

See, me and simon are compensating for tune by just flowing more air via the high flow (higher... flow...:P)

A stock turbo is good for ~180-190awkw in stageas so with a proper tune it really gets up there.

Put it this way. I could make 200awkw+ with only the following engine mods. R34 GTT cooler, GCG high flow, full exhaust, SAFC and SITC. Thats all.

    • And finally, the front lower mount. It was doubly weird. Firstly, the lower mount is held in with a bracket that has 3 bolts (it also acts as the steering lock stop), and then a nut on the shock lower mount itself. So, remove the 3x 14mm head bolts , then the 17mm nut that holds the shock in. From there, you can't actually remove the shock from the lower mount bolt (took me a while to work that out....) Sadly I don't have a pic of the other side, but the swaybar mounts to the same bolt that holds the shock in. You need to push that swaybar mount/bolt back so the shock can be pulled out past the lower control arm.  In this pic you can see the bolt partly pushed back, but it had to go further than that to release the shock. Once the shock is out, putting the new one in is "reverse of disassembly". Put the top of the shock through at least one hole and put a nut on loosely to hold it in place. Put the lower end in place and push the swaybar mount / shock bolt back in place, then loosely attach the other 2 top nuts. Bolt the bracket back in place with the 14mm head bolts and finally put the nut onto the lower bolt. Done....you have new suspension on your v37!
    • And now to the front.  No pics of the 3 nuts holding the front struts on, they are easy to spot. Undo 2 and leave the closest one on loosely. Underneath we have to deal with the wiring again, but this time its worse because the plug is behind the guard liner. You'll have to decide how much of the guard liner to remove, I undid the lower liner's top, inside and lower clips, but didn't pull it full off the guard. Same issue undoing the plug as at the rear, you need to firmly push the release clip from below while equally firmly gripping the plug body and pulling it out of  the socket. I used my fancy electrical disconnect pliers to get in there There is also one clip for the wiring, unlike at the rear I could not get behind it so just had to lever it up and out.....not in great condition to re-use in future.
    • Onto the rear lower shock mount. It's worth starting with a decent degrease to remove 10+ years of road grime, and perhaps also spray a penetrating oil on the shock lower nut. Don't forget to include the shock wiring and plug in the clean.... Deal with the wiring first; you need to release 2 clips where the wiring goes into the bracket (use long nose pliers behind the bracket to compress the clip so you can reuse it), and the rubber mount slides out, then release the plug.  I found it very hard to unplug, from underneath you can compress the tab with a screwdriver or similar, and gently but firmly pull the plug out of the socket (regular pliers may help but don't put too much pressure on the plastic. The lower mount is straightforward, 17mm nut and you can pull the shock out. As I wasn't putting a standard shock back in, I gave the car side wiring socket a generous gob of dialectric grease to keep crap out in the future. Putting the new shock in is straightforward, feed it into at least 1 of the bolt holes at the top and reach around to put a nut on it to hold it up. Then put on the other 2 top nuts loosely and put the shock onto the lower mounting bolt (you may need to lift the hub a little if the new shock is shorter). Tighten the lower nut and 3 upper nuts and you are done. In my case the BC Racing shocks came assembled for the fronts, but the rears needed to re-use the factory strut tops. For that you need spring compressors to take the pressure off the top nut (they are compressed enough when the spring can move between the top and bottom spring seats. Then a 17mm ring spanner to undo the nut while using an 8mm open spanner to stop the shaft turning (or, if you are really lucky you might get it off with a rattle gun).
    • You will now be able to lift the parcel shelf trim enough to get to the shock cover bolts; if you need to full remove the parcel shelf trim for some reason you also remove the escutcheons around the rear seat release and you will have to unplug the high stop light wiring from the boot. Next up is removal of the bracket; 6 nuts and a bolt Good news, you've finally got to the strut top! Remove the dust cover and the 3 shock mount nuts (perhaps leave 1 on lightly for now....) Same on the other side, but easier now you've done it all before
    • OK, so a bunch of trim needs to come off to get to the rear shock top mounts. Once the seat is out of the way, the plastic trim needs to come off. Remove 2 clips at the top then slide the trim towards the centre of the car to clear the lower clip Next you need to be able to lift the parcel shelf, which means you need to remove the mid dark trim around the door, and then the upper light trim above the parcel shelf. The mid trim has a clip in the middle to remove first, then lift the lowest trim off the top of the mid trim (unclips). At the top there is a hidden clip on the inner side to release first by pulling inwards, then the main clip releases by pulling the top towards the front of the car. The door seal comes off with the trim, just put them aside. The the lighter upper trim, this is easy to break to top clips so take it carefully. There is a hidden clip towards the bottom and another in the middle to release first by pulling inwards. Once they are out, there are 3 clips along the rear windscreen side of the panel that are hard to get under. This is what the rear of the panel looks like to assist:
