hay guys i need some advice,

im looking at getting a new turbo for my r33gtst, The car has already a avo intercooler, full turbo exhorst, pod filter, full Link ECU running low boost and im making around 200rwkw on avos dyno.

i want a turbo that has stuff all lag and will give good low down power to mid range no to warried about top end due to, where are you able to use that top end power

so what do people think i will need to get in the power range of 220rwkw.

and will i need to get anything else other then a turbo.

hi flow the stocker i say. best response, cop and epa friendly. 100% bolt on. All the aforementioned turbos may bolt on to the manifold but most will require oil/water fittings. If its a stocker high flow, u can get any mechanic to do it or do it urself. Ie u don't have to take it to a "specialist" workshop that would charge thru the roof.

hey scott

if you want 220rwkw then go for a highflowed of your current turbo, should go same response as the stock turbo

if you want a bit more say 250rwkw then go hks gt-rs (its a gts-t turbo despite the name). it will be a little bit more laggier than your stocker but certainly the most suited to a mild rb25, theres stacks of dyno graphs with rb25 and hks gt-rs

however either way youll need to upgrade the following if you are still using the stock rb25 items:

airflow meter (youll be maxing the afm out)

injectors (youll be running dead on 100% duty or like 5% below at the moment)

fuel pump (it will be running out and can lean the car out, mine leaned out at 172rwkw)

clutch (youll be slipping with 220ish, definetly with 250)

again those arent 100% guaranteed but im maxing everything out at 172rwkw, youd certianly be maxing it out just as much if not a bit more at 200rwkw

      I also just ordered some Frankenstein bolts and side mounts to fit a hard top Just in case I do find one, basically so it doesn't need to be fixed to the car with only the front latch.......and then gaffa tape to keep it in place for the RTN journey from wherever I get it

      If your temps are fine now, you probably won't have any issues with where your vents are as they don't look right up at the windscreens high pressure area, so any differences when giving it the beans for extended happy laps would be minimal, but, they should vent heaps when stuck in traffic  Much like how that reverse cowl on my SS let "visible" heat out when stationary, but, because it was basically at the windscreen my coolant temps on the Hwy actually raised because air was being fed into it at speed (110kph), to only come back down to around 90° when I got off the Hwy And your 100% correct about the NC currently not needing vents, but, if I was to add a turbo, and a oil cooler and intercooler in front of the condenserand radiator, and then take it to the track???? It is apparently a recommend requirement if I don't want to worry about coolant or oil temp issues, but, any of the above are possible scenarios, over time As it sits now, with the triple pass radiator and stock air conditioning system, I have absolutely no issues with either temps or air conditioning efficiency, I've been basically daily driving thie car for the last month, both on the Hwy, and peak hour, bumper to bumper traffic, but, that's pretty much expected from basically a standard engine  Talking about no issues daily driving, it was 39° the other day and I was sitting in bumper to bumper traffic on the M5 and then M7, with the top down, and with the air conditioning blowing nice cold air on my feet, balls, and face, well, there was one issue, my head and arms got pretty sun burnt Note to self: leave a hat and sunscreen in the car for such days 🤣

      I would agree, unless you need something specific to the HV motor/battery side repaired or investigated, any mechanic will be able to perform normal services, but if you prefer, maybe look for a mechanic who regularly services/repairs Nissans, the VQ engines are pretty common in the Nissan lineup.  Sorry, I can't make any suggestions, I don't live in Vic.

      Some of them keep working fine. 9 out of 10 of them end up causing an absolute misery bleeding the system and get thrown on the workshop floor in a tantrum and never thought about again because they were never really needed and just added crap to the car that we could have done without. Same-same with HICAS, A-LSD, and various other stupidities that over eager 10x engineers thought we had to have.

      Not required but appreciated. Super Coppermix Twin even the non-competition model feels like the pedal is noticeably heavier than stock which was pretty well judged IMO. I'll be swapping in the Nismo operating cylinder soon to see how that feels.  Personally I haven't felt anything that justifies replacing the damping loop, at least compared to more modern stuff where the clutch delay valve is actually quite noticeable.
