Well any model GTST that has steel wheels (think r32 might) can run higher boost, the other GTST turbos (33/34) have ceramic turbos which means that it will crack under to much boost... not sure what wheels the t28s have and not sure whats safe on them, generally dont have to many kms on these units so can run higher boost through them anyway :)

Its not to do with the b/b or bush bearing nature of the turbo, its to do with the compressor/exhaust wheels on them :P

Someone feel free to correct me if im wrong?

As usual, I'll correct you.

R32 - R34 GTST/GTT all have Ceramic exhaust wheels.

R33 series II and R34 GTT have a form of plastic Compressor wheel (the wheel on the front on the air filter side of the turbo)

I believe the R32 GTR also has ceramic exhaust wheel. not sure about R33 GTR.

that is why people tend to upgrade to N1 turbo's which are steel wheel.

R32 GTST - R34 GTT (all single turbo skylines) all have Ball Bearing turbo's.

Whitenight - no.. it does not mean you can get 225rwkw out of a T28 from an S15 when on a skyline.

The S15 turbo will be a downgrade to the RB25 stock turbo.

it is smaller and will flow less.

it is also a different bolt pattern which would require more mods to fit.

S15 turbo's are good upgrades for CA18's or SR20's from the S13 range.

and usually also go good for those that Turgo charge their 4agze which is the 1.6L supercharged toyota engine.

You need to get over urself mate :P

I have seen a dyno of 215rwkw on an s15 with a t28 b/b turbo, also did have cams and on an rb25 it may make more power due to the engine... but thats really really at the max of the turbo mate, its not usual to see that kind of figure!

What you believe as a correct fact in regards to a WRX vs R33 could also be regarded as incorrect unless you have both cars in stock standard form to compair?

Do you think you can stop laying into me about trying to help, its not as if i said this is how it is hints y i asked for any1 to correct me which you wanted to do in a smart ass manner... wouldn't of said anything if you would of said 'actually Jazza r32s also have ceramic turbo's' instead of ill correct you again.

Dont think im asking too much to not get attitude do you?

Scathing -  

yeh that would be Brentons right?

I think he had in the region of 225 rwkw with a lot of other mods apart from the turbo.

Scathing, if you are the same scathing on other forums, then you'll know Dale.

and I think that night you were hitting 14 flat in the tree fiddy... if that is you..

Yep, and yep.

Very unimpressed with my ET. There's definitely more in the car, but after I set the 14 flat I just got a little too excited trying to break my NA light-tune barge into the 13's, and ended up screwing up the next couple of launches.

I figured you were talking about Dale before. The other thing about Dale's car is that his suspension is set up for the track. He did soften the dampers out and run lower-than-normal pressures, but the rest of the geometry is still very circuit oriented.

And he was using the D01J's which, with their ultra-stiff sidewalls, aren't the best drag tyre in the world.

the only time I got down there, it was a good day.

Greg (not old man but the other one... Sellby I think it is (the suspension dude)) was there and he helped out a few of us first timers.

anyway, after a few soggy laps in my S14 with S15 stock suspension, I parked it and went for a drive with Dale.

after seeing/feeling the way his car taking the corners with the teins and DJ01's, I didn't take my car back out.. I was quite scared being in his car and the corner speed and late braking that he could do.

Brenton was there and he put on a set of yokahama slicks.

hahahaha

I had asked him to take me for a spin in his at lunch, but after experiencing what Dales car co do with less power (he had his boost controller down to 11psi) and with just semi slicks, I chickened out of a ride with brenton..

hahahahaha

Yeah s14 i would say 170rwkw to 180rwkw and a 1/4 mile in the mid to high 13's...just my 2 cents

My mate has these mods and dynoed 160rwkw but that dyno reads 10% low, so it will also depend on the dyno you get the reading from, gear, tyre psi and dyno mode etc.

      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)

      By Kapr · Posted

      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.
