Back in the day you your required a highflow to push over 200rwkw.

These days the dyno's push 200rwkw on stock turbo's so I believe its just the dyno's reading a little happy.

The dyno I run on typically 190rwkw is what a stock turbo'd r33 can achieve with the usual boost - 12psi, tune, exhaust & fmic. Throw an adj cam gear on and you can squeeze it a little over 200rwkw.

As R31Nismoid says the power figures 'these days' just don't add up with the MPH.

yeah mine was done by someone in melb and on 10psi and im making just shy of 185 (on a spazz tune that has huge flat spot) only wished Toshi would come to melb so mine can be fixed up!

I dont know about "safely" on the std turbs, some shit themselves at minimal boost my concern is how it drives, mines a shit bastard to drive afterwards as fark all light throttle and cruising adjustments are made, mine feels like I have lag as soon as the air gets cooler...although I like the extra 20 odd kw, I really dont think its worth the headache if your car is in standard form.

to answer your questions you cannot compare the "drive" of my setup now and before. before it felt like shit. rough, flat spots, not a very smooth band of power at all. now it feels much more refined but at the same time injecting more power with each gear. even at low rpm on low boost feels so much smoother.

so rb20's will just make 200rwkw with rb25 turbos but rb25's wont?!?

depends if your from WA or not i think mainly.

Generally you see RB20s make around 170-185rwkw on 14psi or so with the RB25 turbo (going by the results in the RB20 dyno thread)

i think he meant R32s with full RB25DET conversion. no way a RB20 with RB25 turbo can make 200kw.

If you want a remap. Sam AKA Dr Drift does them and is conveniently located in Melbourne ...

i don't think he does the R33 Remaps, he installs a daughter board on the R33 ecu making it live tuneable... and that costs over 1k plus tune costs..

or else id be happy to go to him for a remap..

All figures aside as i believe that you can go to 3 different dyno's and get 3 different readings... how confident is anyone about how much power they are putting out... 1/4 mile times also is not all about power i think set up and driver ability come into it as well. ..... I am very happy with the way my car performs now after a remap from Toshi.... I am not going to modify my car any further and it did seem to have a flat spot in the mid range before ... after the ecu was changed over i noticed a big difference in the way the car pulls under heavy acceleration was much better than before and appears to do it through out rev range, car seems much quicker, smoother and power is more linear (i did up the boost a little as well)...

i just got 509kms out of 52.7 ltrs was mainly open road driving with occasional squirts thrown in as i was wanting to see how good my economy was as well (did change O2 sensor) but all in all DRIVABILITY , power and fuel economy is all good and im very happy for the money I spent. I dont have the fastest car on the road but it is quick and it runs well :-) was a good option for me........my 2 cents worth.....

its wierd how wa dynos make so much power, but then when you send over "eastern spec" mainline dynos over for autosalon we still make more power than you... maybe the air is just more oxygenated over here?!? haha

ooooooooooooooooo really

i agree with you. its easily not the fastest on the road but damn i feel it is definitely quick enough now. and quick enough to put a lot of cars to shame too. before i dunno i just didnt have the confidence that the car was running as well or was as quick as it should be. this remap was all it needed.

You theory is flawed.

By what you're saying, I should be making 220rwkw because I have an RB25 turbo on an RB30..

A turbo will make the same power on whatever motor it is on because it can only flow "so" much air. Smaller or larger capacity will just make the power later or sooner.

I also resent the WA reference, not all of us are dyno fiddling dodgy brothers :D

I second that.

I am running a RB20 with normal bolt on mods, GTR injectors, GTR fuel pump, R34 RB25 turbo and a Nistune Remap and I am making 195kw.

Next thing needs to be AFM.

nice curve impressive. i didnt think R32s with RB25 turbos could make so much power

Cheers, unfortunately I don't know what the before and after was for the JUST the remap, as I installed the turbo and injectors, towed it to the shop and got it tuned.

So i noticed a huge difference, but it wasn't all from the tune obviously :blink:

    • Back again. I returned to Japan in Jul/Aug to spend time with the car on my birthday and remind myself what all the sacrifice and compromise is for. It happened to line up with the monthly morning meet in Okutama, which I have been wanting to go to for a long time. It's a unique event at a unique spot with really rare, interesting, and quirky cars. It's where all the oldheads and OGs gather. The nighttime scene at DKF certainly has its place and should be experienced if you're into cars, but there's too much bad attention and negativity around it now. IMO the better time is Sunday morning at DKF or Okutama; it's more chill and relaxed. I'm glad I was finally able to go, but not sure it's worth the drive from all the way from Nagoya immediately the day before, unless I was already staying in Tokyo for the days right before the meet, because you have to wake up quite early to make it in time. Funnily enough though I didn't drive the car all that much this trip because it was just too damn hot. While there were zero issues and running temps were nominal and the A/C was strong, RBs already run crazy hot as it is. Sure, it took it all like a champ but something about driving these cars in the ridiculous heat/humidity bothers me and makes me feel like I'm asking too much of it. I'm just me being weird and treating the car like a living thing with feelings; I'm mechanically sympathetic to a fault. Instead I was mainly driving something else around - a KX4(silver) 2001 X-Trail GT, that I acquired in May. There's a few different flavors to choose from with Xs, but visually it's the Nissan version of the Honda CR-V. Mechanically it's a whole different story as this, being the top-trim GT, has an SR20VET mated to a four-speed auto and full-time AWD! It was a very affordable buy in exceptional condition inside and out, with very low mileage...only 48k kms. Most likely it was owned by an older person who kept it garaged and well-maintained, so I'm really happy with how it all worked out. It literally needs zero attention at the moment, albeit except for some minor visual touch-ups. I wanted something quirky, interesting, and practical and for sure it handily delivers on all three of those aspects. I was immediately able to utilize the cargo and passenger capacity to its full extent. It's a lot of fun to drive and is quite punchy through 1st and 2nd. It's very unassuming -in the twisty bits it's a lot more composed than one would think at a glance- and it'll be even better once I get better tires on it(yes, it's an SUV but still a little boat-y for my liking). So...now I have two golden-era Nissans in silver. One sports car and one that does everything else; the perfect two-car solution I think👍 The rest of the trip...I was able to turn my stressed brain off and enjoy it, although I didn't quite get to do as much as I thought. I did some interesting things, met some interesting people, and happened into some interesting situations however, that's all for another post though only if people really want to know. Project-wise, I went back to Mine's again to discuss more plans and am hoping to wrap that up real soon; keep watching this space if that interests you. Additionally, while working in the tormenting sweatbox that is the warehouse, I was able to organize most of the myriad of parts that my friend is storing for me along with the cars, and the 34 has a nice little spot carved out for it: And since it can get so stupid hot in there, that made it all the more easy -after I was standing there looking at the car and said 'f**k it'- to finally remove all the damn gauges that have mostly been an eyesore all this time. Huzzah. The heat basically makes the adhesive backing on the gauge mounts more pliable to work with, so it was far less stressful getting this done. I didn't fully clean it up or chase the wiring though; that will happen once I have the car in closer possession. Another major reason to remove all that stuff is to give people less reasons to get in my car and steal s**t while it's being exported/imported when/if the time comes, which leads us to my next point... ...and that is even though it's time in Japan is technically almost up since it's a November car and the X would be coming in March, I'm still not entirely sure where my life and career is headed; I don't really know what the future looks like and where I'm going to end up. I feel there's a great deal of uncertainty with me and as a result of that, it feels like I'm at a crossroads moreso now than any point in my life thus far and there are some choices I need to make. Yes, I've had some years to consider things and prepare myself, however too much has happened in that time to maintain confidence and everything feels so up in the air; tenuous one might say. Simply put, there's just too much nonsense going on right now from multiple vectors. Admittedly, I'm struggling to stay in the game and keep my eyes on the prize. So much so in fact, that very recently I came the closest I ever have before to calling it quits outright; selling everything and moving on and not looking back. The astute among you will pick up on key subtext within this paragraph. In the meantime I've still managed to slowly acquire some final bits for the car, but it feels nice knowing there's not much left to get and I'm almost across that finish line; I have almost everything I'll ever want for my interpretation and expression on what it is I think an R34 should be. 'til later.
    • Thanks for that, hadn’t used my brain enough to think about that. 
    • Also playing with fire if they start to flow more air down low than what the stock twins can. It's not even up top you need to worry, it can be at 3000rpm and part throttle and it's getting way more flow than it should.
    • Any G40/1000 or G40/1250 results out there?  
    • You still want a proper tune on the stock ECU though. Stock tune + stock ECU with GT-SS/-9s is probably playing with fire if you're running more than stock airflow/power.
