Hey guys i have a R33 that has the following mods

Trust catback

3" dump pipe

de cat

blitz pod

boost tee 9psi

walbro fuel pump

Last time its returned 255hp 188KW at 9psi (dont want to go any higher and goes into R&R after10psi)

i have a Power FC, plazaman plenum, front mount and tomei FPR to go on next but turbo choice

Is the 3076R to small with the .63 rear for the 25? and would the internal gate or external gate be better i would love to run external gate but is iit worth the extra money

i want fast response and good midrage to redline pull i want to use the car for daily driving, drift and every now and agian drag and curcuit. power comes second to response and relaiblilty for me i wont be pushing it to the extreme but i want headroom.

Yes i have upgraded all the suspension and braking in preperation for more power :/

IMO the .63 is to small for the GT3076 (given its a 300rwkw(+) turbo).

If you want super response and a .63, then a GT3071 fits into the equation there much better.

It should make around 250rwkw give/take and should still hold nicely to redline. It won't be anywhere near the top end the GT3076 will have (in a .82)... but all comes down to what you want.

More response or more top end. Something always has to give.

External gate is not required either way.

Are you using factory exhaust manifold or not?

3076 .82 is still boring and small

go bigger if u want something that will scare u a little.. maybe 3582r .82 mmm

way to much lag for a 25. I wouldnt go that setup unless it was a 3litre. Even still i think the gt3076r 0.82 in a 3litre would be my first choice.

Id go for an external gate. I regret not getting one on my gt3076r

might be a bit laggy but once it comes on its fun :D

3076r arent exactly the most responsive turbo either. i dont see 20psi until 4100rpm

How would it scare him making 300rwkw?

All it's going to do is be overtly laggy for the power and a silly suggestion really...

If there was intent to make 370-380rwkw then fine, GT35...

Fact is he isn't so getting a turbo that's oversized, for upto 300rwkw, and will make it overall slower - totally against what the OP wants anyway.

cause ive got near 300rwkw with 3076 .82 and its boring only going off proof :D been in 350kw gt3582 and let me say alot more fun and alot f**king faster, but hey thats me

lol already bored with the 3076? should've kept your old turbo and get a set of cam gears :D . Well. I'm making 321rwkws out of it (hypergear build 3582 in .82 housing) at moment. I'm seeing full boost on 4300RPM, not much on 1st and low 2nd. but 4000rpm+ on 2nd, 3rd, 4th it flys. Need to get more traction.

and you need some thing bigger then .63 to work with a GT3076 core. But should be good enough for about 270rwkws mark if you can hold boost.

He has a factory motor mate... come on... use some logic.

Of course a 350rwkw car is going to be more "fun" above 100km/h than a 300rwkw car. On the street however you've gotta argue what's going to actually be faster.

Mine with 280rwkw is virtually perfect, when it had 370rwkw it was just impossible.

Running 350rwkw through a factory motor that is going to see some circuit/drift... It won't last very long at all.

With a 3071 it will cover EVERY single base thing OP wants and still be in the realm of reliability.

yeah i understand nismoid.. just dont want him bolting on a so called balanced turbo that isnt going 2 give him that "wow" factor lol not saying 3076 is completey boring but it just doesnt cut it i dont think even for 300kw range hey.. maybe im fussy?

sell it to me then...pm me if you REALLY want to get away from it.

must be internally gated though

Boring??? Small???

The 3076.82 i had on my car produced 370rwkw and had full boost by 3900rpm. Smashed anything on the rd and IMO a more of a handful than the GT3582.82 i have now.

Light switch power from low RPM compared to the gradual push of power from the 35R.

They are not as laggy as you think, a mate is running one on a stroked 2.4ltr 4cc vr4

    • 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.
