im running a kkr560 on my rb30 single cam motor, plenum, exhaust top mount manifold and i have the internal gate flap blocked off . its making 5psi at 2500rpm and 13psi at 3500rpm

Dyno graph?

I assume you have an external gate?

guys we dont have any dyno here and car is tuned in my garage by me, here is GTECH RR graph

RB480det.jpg

modifications are:

FMIC 600x300x75

APEXI FC absolutely not tuned because i dont know what to do and how todo with that:)

KKR480 on 13 PSI boost

front mount plenum

and thats all fuel pump is sdandart and exhaust is not changes still using factory setting:)

265 HP on rear

ful boost on 5000 till 7500 RPM

guricha dude, you need to get that power fc tuned. If there's no dyno's over there then road tuning is the next best thing......which you already seem to be doing.

To tune the Power FC properly you'll need on of these http://www.fc-datalogit.co.nz/datalogit.html.

And also a wideband O2 sensor if you don't have one already http://www.plxdevices.com/products/dm200/smafrcombo/

And you'll also need a laptop.

Then once you have that, you'll need someone who knows what they're doing to tune it. Unless you want to try your hand at it and do some experimenting.

Thanks dude, is there any chance to lern how to tune it, because actualy there is no person who can tune it here i know that funy but Georgia is the one of the country who likes more BMW than Japanese:) so am expecting wideband for next week but still its problem how to tune FC, and what should be wideband air fuel ratio?

guys i have read the entire thread and i still don't know is this a good turbo or a bad turbo?

my mods so far:

FMIC 600x300x75

Cat back 3" exaust

HKS BOV

Apexi Pod

But if i get the kkr480 i'll have a otomoto dump and Nismo front pipe to join up.

Everything else is standard atm including ECU, the kkr480 has the race actulator spring (=1-2bar)

idea's? Hame

ok with a microtech lt10 mine makes 240rwkw @ 18psi, starts hitting boost at ~2500rpm

how you make it to flow early? do you still use internal weisgeit? because mine is going to boost near 4000 but have 15 PSI

aparently the turbo i am after is set at 15psi, i dont have any other modifications apart from what u listed above, so still have stock fuel set-up etc think mine will boost late? also have stock ECU...but what u 2 just posted..they are some serious numbers. hame

so the question i am asking, is one are they easy to fit to the r33 gts-t..

and two..even if they run 15psi-22psi on the standard engine with the modifications i have already specified, will this be a problem

and three should i get my ECU remapped, and who can do it around brisbane?

they aren't hard to fit, there is a bit of modifcation 2 the water lines, cooler piping,silicon 90 degree elbow,intake piping and fab up a dump pipe

pretty simple stuff if ur mechanically minded.

buy an after market ecu powerfc or link or haltech or something along those lines.

you will find the kkr turbo wont hold boost very well, it will spike and prob end up runing around the 16-20psi mark like all of them.

and if u run this on stock ecu ur gonna blow ya car in no time:)

Seriously? Blow it? Not even if i have the ECU re-mapped? I have the otomoto dump pipe for easy fitment, already have the intake pipe for it, cant afforad the aftermarket ecu atm, but will be able to eventually, if i drive around off boost alot you still think i will have problems, untill of course i buy an aftermarket ecu. I will also be putting on a Greddy intake manifold at the same time. This kkr480 is only oil cooled i'm asured of that. it is currently on a rb20 s13 with stock ecu..u think this is bad? :cool:

    • As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year. 
    • I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
    • 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.
