Good to hear that this has worked well for you mate. Now time to dyno it to have a power figure to work with :P

Well, I got it dynoed a week ago, completely stock turbo 5psi, 134rwkw which is pretty basic for a stock rb25det (auto), i was told boost it to 10psi could get another 30rwkw maybe? will have to find out :)

good o hear :yes:

Hypothetically i get an increase of 30RWKW, that will make it 165RWKW, what would be the next best thing to do to this engine to make it say hit the 200RWKW mark and be safe for stock engine and running gear?

just after some informed opinions, the next best mod or change to get it to the 200 RWKW mark :)

high flow turbo or a garrett aftermarket turbo GT3071x

thanks, i was hoping there could be other mods without changing the turbo? or can you get a decent turbo for a few hundred and just straight swap? :) just after 200rwkw :P

If you haven't already:

  • 3" exhaust turbo-back exhaust
  • a front-mount intercooler

That with an ECU tune should see you around 200rwkw

Hell, my R34 was doing 182.7rwkw with just a 3" exhaust, and an intercooler - still on factory boost solenoid (saw peaks out to 8psi).

I've since fitted a 10psi R32 actuator; I would hope mine will do in-excess of 200rwkw once my ECU is tuned (I have an un-tuned nistune fitted)

Unfortunately in your case with an R33, a nistune is a less straight forward exercise, but an ECU (R32/Z33-based nistune, PFC, etc) should be your next step assuming you already have an exhaust, FMIC. This will help get rid of the factory overly-rich AFRs. It might also be worth considering your fuel-pump if this hasn't been replaced already. They do tend to wear, and require replacement.

Hi, yes i have FMIC and CAI and 3inch turbo back+hi flow cat, stock 5psi actuator seen 134rwkw, now i have r32 actuator im hoping at least 30rwkw increase, and then push for another 30 with a tune or something without changing turbos, surely you can reach 200RWKW off a stock rb25det with little mods I have mentioned? thanks

And then for some strange reason, at some point after these mods 200kw just wont satisfy any more. Keep in mind that everything else on the car will need replacing/upgraded sooner or later if the power output is increased significantly.

Once you make the decision to modify your car, there is no turning back.

Just a warning haha

I ran my car with the stock turbo on 12.5psi making roughly 215rwkw. The supporting mods were, Coilpacks, FMIC, Turbo back exhaust, Power FC, 740cc injectors (however you won't need to upgrade injectors or AFM to hit 200 rwkw). So a small list of mods should see that power figure :D

just chuck it on a hub dyno and make 200 as is!?

heey guys, just wondering since changing the actuator to R32 should I get a tune? like the car runs quicker but still average at the 0-60 mark? can i tune my standard ecu at all? will it make much difference? or wat should i, could I do to make the car have more response?

mate, take this advice onboard and run with it coming from sum1 who has spent hundreds of thousands of dollars on cars in the past 5 years...

like a few other members said once u get to that "200kw" mark u NOW want once u acheive it u wil want 250, then 300 n so on, TRUST US, u wil, its a like a drug lol

go straight for a power fc, easy to tune and retune afta other mods r put in place (always pop up for sale on here and ebay)

next would b fuel pump and z32 afm

afta that id go coil packs, and direct replacment injectors

and finally turbo (either garret or precision)

if i were u id save all ur penny and do this at once, yes it may cost arounfd 5grand but if u do 1 thing at a time, retuning it everytime to support the next mod

u wil spend thousands just on tuning when u could b spending that on quality upgrade mods and get a 1 off tune...

beauty of have say 250-300rwkw is if u want that 200kw u want just turn the boost down (high boost switch is fun n convenient :)

i think every1 here wil agree with this post, save time, money and go have fun....

Yep totally agree with the post above. Spend all the cash on buying all the upgrades then save and have them put in or DIY and then get a tune. Otherwise you will end up paying a crazy amount on a mod upgrade and tune.

Most things you won't worry about getting a tune with, for example putting that actuator on, you really don't need a tune but look at getting an aftermarket ecu as the stock ecu's are no good for tuning :D

So you want more and more and more power, and a GTR style body kit .... why don't you just buy the right car = sell your Gtst and buy a GTR. It is the only real answer. As everyone has said above, you will continue spending significant amounts of money to get more power .... start on the right foot and just buy a GTR!

    • Hi,  Just joined the forum so I could share my "fix" of this problem. Might be of use to someone. Had the same hunting at idle issue on my V36 with VQ35HR engine after swapping the engine because the original one got overheated.  While changing the engine I made the mistake of cleaning the throttle bodies and tried all the tricks i could find to do a throttle relearn with no luck. Gave in and took it to a shop and they couldn't sort it. Then took it to my local Nissan dealership and they couldn't get it to idle properly. They said I'd need to replace the throttle bodies and the ecu probably costing more than the car is worth. So I had the idea of replacing the carbon I cleaned out with a thin layer of super glue and it's back to normal idle now. Bit rough but saved the car from the wreckers 🤣
    • After my last update, I went ahead with cleaning and restoring the entire fuel system. This included removing the tank and cleaning it with the Beyond Balistics solution, power washing it multiple times, drying it thoroughly, rinsing with IPA, drying again with heat gun and compressed air. Also, cleaning out the lines, fuel rail, and replacing the fuel pump with an OEM-style one. During the cleaning process, I replaced several hoses - including the breather hose on the fuel tank, which turned out to be the cause of the earlier fuel leak. This is what the old fuel filter looked like: Fuel tank before cleaning: Dirty Fuel Tank.mp4   Fuel tank after cleaning (some staining remains): Clean Fuel Tank.mp4 Both the OEM 270cc and new DeatschWerks 550cc injectors were cleaned professionally by a shop. Before reassembling everything, I tested the fuel flow by running the pump output into a container at the fuel filter location - flow looked good. I then fitted the new fuel filter and reassembled the rest of the system. Fuel Flow Test.mp4 Test 1 - 550cc injectors Ran the new fuel pump with its supplied diagonal strainer (different from OEM’s flat strainer) and my 550cc injectors using the same resized-injector map I had successfully used before. At first, it idled roughly and stalled when I applied throttle. Checked the spark plugs and found that they were fouled with carbon (likely from the earlier overly rich running when the injectors were clogged). After cleaning the plugs, the car started fine. However, it would only idle for 30–60 seconds before stalling, and while driving it would feel like a “fuel cut” after a few seconds - though it wouldn’t fully stall. Test 2 – Strainer swap Suspecting the diagonal strainer might not be reaching the tank bottom, I swapped it for the original flat strainer and filled the tank with ~45L of fuel. The issue persisted exactly the same. Test 3 – OEM injectors To eliminate tuning variables, I reinstalled the OEM 270cc injectors and reverted to the original map. Cleaned the spark plugs again just in-case. The stalling and “fuel cut” still remained.   At this stage, I suspect an intermittent power or connection fault at the fuel pump hanger, caused during the cleaning process. This has led me to look into getting Frenchy’s fuel hanger and replacing the unit entirely. TL;DR: Cleaned and restored the fuel system (tank, lines, rail, pump). Tested 550cc injectors with the same resized-injector map as before, but the car stalls at idle and experiences what feels like “fuel cut” after a few seconds of driving. Swapped back to OEM injectors with original map to rule out tuning, but the issue persists. Now suspecting an intermittent power or connection fault at the fuel pump hanger, possibly cause by the cleaning process.  
    • For race cars, this is one part where I find having the roll cage bar having gone through a hole in the floor better than the build it up on a ledge inside... The Merc I help on, the main hoop ends are marked on the car, and the jack is marked... Jack goes under a few inches and lifts one whole side of the car up... Removes that fight for long slim jacks for race car duties!   My biggest issue for the daily drivers I work on, is my jacks don't go high enough. The jacks start out on a few blocks, jack it up, then start a second jack under it on more blocks, and then I can get an axle stand under it. My axle stands are presently in use, and are nearly fully extended. The car is sitting with barely more than a cm of clearance to get the wheel off the studs! Sarah's Kluger is the same, as it has an ungodly amount of droop available in the suspension and a distinct lack of good jacking points!
    • Happy? Yep, my to do list is getting shorter and shorter. Either this light approaching is the end of the tunnel, or I'm about to be hit by a train... Ha ha ha   Also, Duncan isn't that far out of town that you need to make a multi day drive out of it. 😛
