hahahaha, thanks guys. was looking at a GTST with a 25/30 in it but i had a chat with my mates and would rather put 5k into a stock rb20. 240rwkw sound alright to me for a daily driver....

People often comment on the poor performance of the RB20, mostly its lack of torque. BUT, consider the R32 has less weight, shorter gearing also helps mask any lack of row rpm torque. Also the lack of stump pulling torque helps traction onto boost, where you can still make big hp through the mid range and up top.

LOL, though i am a scratched record...some copy and pastes from other posts...

And my parting comment will be have a look at this....

STD RB20 with a turbo and ECU upgrade

Compared to a std turbo RB26 with Poncams, and same dyno and same tuner

As you would expect the Rb26 spanks the RB20 down low, but in the rev range that you use at the track the RB20 punches well above its weight!!!!!!!!!!!!!!!

And...

Here is an R34 GTT on the same dyno, same tuner with Poncams and GCG high Flow, and then a very similar car out of NSW (though it had different tuner and dyno)

So, dont discount the performance of an intelligently modded RB20, all with std internals.

Sure there are better engines around, though for the money??? Well the only cars quicker then me at the track are 330-360rwkws well modified GTRs. My little std RB20 with a turbo upgrade manages to go quicker then all the SR20s and RB25s etc, some built, some with just turbos, even many of the lesser modified GTRs makign under 300kws. So if the RB20 was that far behind in performance then this would not be possible. Spend the money on getting some more poke out of the RB20 and what money you can on suspension, clutch and brakes to ensure that the all round performance of the car makes it a quick package :P

      What brakes on R34 GTT(Europe)

      By Duncan · Posted

      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

      What brakes on R34 GTT(Europe)

      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.

      Place the new daughterboard in the case and mount it using the 3 small black rivets provided, and reconnect the 3 factory ribbon cables to the new board Then, use the 3 piggyback cables from the daughterboard into the factory board on top (there are stand offs in the case to keep them apart. and remember to reconnect the antenna and rear cover fan wires. 1 screw to hold the motherboard in place. Before closing the case, make a hole in the sticker covering a hole in the case and run the cable for the android unit into the plug there. The video forgot this step, so did I, so will you probably. Then redo the 4 screws on back, 2 each top and bottom, 3 each side and put the 2 brackets back on.....all ready to go and not that tricky really.
