whos the dude on here who just got a GTRS tuned on a 33? he got i think just over 250rwkw on 1bar, so i think there should definitly be more in it with more boost, which would put it quite ahead of the 2530- which is a good solid street turbo, which can only be faulted for running out of a bit of puff at the very top end.

For the price of the GTRS's at the moment they are a steal.

There seems to be lots of support for the 30xx series, looking at dyno runs the power looks like a light switch (i even think the 2835 looks to come on pretty hard) are these really good for the street? surely 3rd gear would bag street tyres just coming onto boost, let alone trying to accelerate hard in 1st or 2nd? Sounds like fun, but frustrating when lesser powered cars beat you to 100!

I have a 2835proS on the way at the moment. Going to have to run R-compounds full time, as the 2530 already fries tyres with its paltry 220rwkw! :)

building a RB25DET with a TD06-25G, nice laggy turbo with good topend power, and a misfiring system to keep the turbo spooling while I'm off the throttle. The one that I've bought is a metal sleeve thingamajiggy (can't remember the name) so its not steel bearing or ceramic, and can withstand a lil bit more punishment than a standard turbo.

As a standard swap/upgrade for a R33 RB25DET i'd say get a 2530, but I dunno how they react to RB25DET Neo's.

Funky you have been talking about this setup for about 1 year now, when the hell will you get all these antilag thingamergiggies done?

Is the 2835pro s going to fit on the stock manifold without modifications?

As for traction, good tyres and decent suspension setup helps alot!!!

i hope so! i think it all bolts up. Kit comes with its own dump and all the lines. I think the one thing ill need is a new intake pipe as the compressor inlet mouth looks big, but im fairly sure its a blot on kit.

can someone with ~280rwkw comment on drivability? are these cars still fast at speeds below 100 or is it just wheelspin city?

While i love power, it makes you slower if you cant get it down!

Damn impressive resutls...are you sure it was only 13psi:confused: I have read of those sorts of power figures at 1.3bar. Is it a std RB25:

No its not standard. I dont know what has been done other than bigger cams, injectors, external wastegate, it was a import this is how it came. It was dynoed by Brad Sherriff in Tassie.

      Possible swap on R34 RB20DE NEO?

      By Kapr · Posted

      Hi. A little bit of an update. It maybe(hope not) looks like i would need a new tranny(it would be "maybe" a cheaper or better option anyway) So i need some info. I know i need a different propshaft(i can make custom one) LSD is not a problem cuz the engine will be still(for now) N/A RB20. So if i buy RB25DET NEO tranny...is there something else i need? I read something about push/pull type but i do not know if i need to "change" something or i can just plug n play onto my engine a go? Thanks for the advice

      Turn signal wiring question

      By OakvilleGTR · Posted

      Good morning all, Bit of a random question but figured I’d finally throw it out after wondering for a long while. Before I start, I'm hoping to do this purely out of personal preference. I think it would look better at night, and don't mind at all spending a few hours and dollars to get it done. I've copied this from a non-Skyline specific forum, so I apologize for the explanation of our headlight switch setup that we all know. Here we go: Zero lights (switch off) Parking lights (switch position 1) being a rectangular marker on the outside of the housing, my low beam being the projector in the centre (position 2), and a high beam triggered by my turn signal stalk. Most North American cars I’ve owned of this era have power to the amber corner (turning indicator) light as part of the first switch (parking lights). I’d love to have these amber corners receive power when the headlights and parking lights are on (headlight switch), yet still blink when using the turn signal which is of course a separate switch. Hopefully I’ve explained my question correctly. Is anyone aware of a way in which I might be able to achieve this? Thanks in advance

      Mistakes were made, my R34 Story

      My heads are cathedral port! It's likely possible, but I don't want to add any extra moving parts (I know they don't move) between the heads, manifolds, etc. It will also affect how injectors/fuel rails etc sit and I don't really know if it would change how the FAST manifold goes/sits/fits. I have the LS6 steam pipes already as I have a very late LS1 block so it should be fine. I couldn't find anyone who had ever actually used one for this purpose, it seems 100% of people grind the water pump. The thermal spacers are 12mm and are half way to the cost of the newer water pump anyhow... so if it comes to that I suppose I'd rather buy a new pump. The bearing in the pump I do have is a little.. clunky, but it hasn't done that much time and I never noticed it when the car was together in the past few years, so..

      Lower A arm Skyline v35

      By sonicii · Posted

      The bushing has failed, not all that uncommon for a car of this age.  Any mechanic should be able to push in a new bushing for you, or you can probably buy the entire lower control arm, complete with bushes.

      Could you not use "thermal" spacers to give the clearance, like the ones I used between the blower and head? That raised the manifold height by around 10-15mm Albeit the ones I used were for cathedral ports, but I assume they have similar for rectangular ports????
