Just finished of the dyno with my 200sx S14a Z-Edition RB20DET. I made 449,8hp@1,45kg (8160RPM) boost at the crank.

Quite pleased with that on a stock bottem end. just replased all bearings and ARP bolts all over.

297KW @the hubs.

How did you arrive at the figure of 449.8hp at the crank?

That dyno sheet shows 275.7kw (372hp) at the wheels (hubs).

Corrected power (engine) is 297.1kw (401hp).

Still some very nice power, but quite similar to what AD4M is making here (383hp at the wheels) on a stock RB20.

I'd say his quoted figure is a bit more realistic. To only lose 20kw through the drive train (whilst revving the crap out of it, max power at 8160rpm) isn't very realistic at all.

What turbo is that running? Looks pretty laggy, bit too laggy considering the power it makes.

fark yeah nice effort. But my question is why an rb20 into an s14? Never heard of Z-Edition??? They dont come stock rb20det im guessing as its an older engine

Hi, The 200sx S14a Z-Edition was sold in europe. Only 200 made. They came with Eibach lowering springs, Remus sports exhaust, 19" BBS rims and fully leather interiour. It came with SR20DET but I have done a rebuild with a RB20DET from a R32GTS-T

Lose the GTR badge mate. If I saw your car on the street with that I would just laugh and think you were another knob who didn't know the first thing about what he was doing.

Hi, thanks for youre taughts. But we have called it Sky-Lite :P

I run a Turbonetics 60-1 with a A\R .63 exhaust housing. I will achive boost about 5-600rpms earlier by setting up my wastegate with vakum in bottem, and boost line fro boostsolonoid on top.

Hi, I run a 3.6diff and a S13 CA18DET tranny. Therefore the loss in drivetrain. It does well over 300KM`h with that gear ratio.

Good work :P

RB20's rev well and sound sooo nice

got to love RB's 297 rwKw and a mear 369.9 nM of torque, rev the ring out of them and go nowhere. Dam impresive result mate.

HUB and RWKW are a fair bit different, rwkw is less again

^^^ Yeah, rwkw is about ~15-20kw less than measured at the hubs.

If you've got a 3.6 final gear, you should probably look into getting the stock 4.363 in there, much better match for the RB20, covers up its lack of bottom end a bit and keeps it in top end more. Unless of course you regularly need to go over 300km/hr?

      I would just put EBC back on the "I would not use their stuff" pile and move on.

      Can I suggest you try EBC directly again and link them to as many competitor catalogues as you can to show their listing is incorrect, eg https://dba.com.au/product/front-4000-series-hd-brake-rotor-dba42304/ If you have access to an R33 GTST VIN and your VIN, you could also use a Nissan Parts lookup like Amayama to show them the part number is different between 33 GTST and 34 GTT which may get their attention

      So i got reply from EBC and they just this site where you can clearly see those 296mm fronts on R34 GTT. I send them photos and "quotes" that 296mm are not for 34 GTT and they are too small. But it will be very hard to return them cuz nobody here knows 100% and they just copy those EBC catalogue :-D https://ebcbrakesdirect.com/automotive/nissan/skyline-r34

      From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.
