Hey guys

have 201rwkw on a r33 series 1 gtst

power fc

Hiflow cat

AVCR

FMIC

CES Racing 3" split dump

Set on 12psi at the moment

I have purchased a hiflow turbo ( plain bearing)

at the moment gettin new bearings put in it ( not ball bearing)

I'm going to be uppin the boost abit to a safe level.

Should i consider getting other things at the same time

like

Walboro fuel pump ( I did buy a bosch pump 040 but, i want to put it in myself and im not goin to bugger around with making a bracket for it.)

Injectors

Z32 AFM

Any help would be much appreciated

I would like to get close to 230rwkw

Thanks

gtr pump will be cheaper and direct fit and run at 12v instead of the walbro needing to run at 15volts. z32 is direct swap powerfc (needs AFR check) and get some s15 manual injectors (480cc) and it should all be fine

just the standard r33 series 1 turbo im guessing

plain bearing

Steel wheels

it is at turbo australia at the moment, getting new bearings put in it and rebalanced

as it did have a lil bit of movement in the shaft

Not sure of the specs and whateva, soon will find out when i get it back.

You will be a little dissapointed with that turbo bazr33, I know, I`ve been there.Read a couple of posts up on hi-flowed injectors and it may give you some idea where your headed.I did try the cheap hi-flow turbo and didn`t like it.To slow.Not painful but got a gcg hi-flow and it was much better.I would certainly spend the money and go ball bearing.Anyhow, if you get the z32 afm and some injectors try 14LB boost and you will be happy, very happy. :wavey:

You shouldn't need injectors to get to 230rwkw at all. You can save hundreds here. A new fuel pump and a fuel pressure regulator should be plenty to get that power.

Speaking with my personal experience where I've made 240rwkw with pump and fpr. However, I'm limited to 16psi where my turbo wants to run 20. Injectors are next but for 230rwkw I wouldn't bother.

  • 5 months later...

have 230rwkw

with walbro fuel pump and the hiflow plain bearing turbo set on 12psi

(also the mods i have listed at the start of course)

next is 555cc injectors, z32afm and fuel reg and goin to 18psi

also have just purchased a aerospeed exhaust side cam gear

so i'll see if that makes any difference

240rwkw would be acheivable on standard injectors and running a fuel reg, as on standard injectors im only 10kw away from it.

with the 555cc injectors that im going to put in, with the z32 afm aswell

we are hoping to hit 260rwkw, and cant see why that wouldnt be possible

Yes the plain bearing will get hotter and take longer to spool up, but aslong as theres sufficient oil flow, and not sitting on 18psi everyday,every minute, i think it will be fine.

But if the turbo does decide to shit itself, it will be a rebuild or new one.

Obviously im just wanting a safe tune, 260rwkw is going to be my limit, with still having a standard engine.

Will let you guys know if she blows or if she goes and hits the mark.

    • 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. 😛
