I have an R34 GTR (not v-spec) and I've got a cat back exhaust and am looking at getting the following dump/front pipe kit from nengun:

http://www.nengun.com/trust-greddy/extention-front-pipe

There are two options for the r34's though, one with a flange attachment and one with an exhaust temp sensor attachment. I know that the v-spec's MFD display's exhaust temp so I'm assuming that the one with the exhaust temp sensor attachment is for v-spec's and the flange attachment for non v-spec's. Could someone please confirm whether this is the case or not before I charge up the credit card???

Please don't flame me for the noob question but I've searched and found conflicting results. Some say r34 gtr's come with ceramic turbo's and others say ball bearing. Could someone please clarrify this?

Much Appreciated,

Stick

Cheers for that R31Nismoid.

Is this a good dump/front kit or are there better kits on the market? I guess the answer to that question probably lies with my goals for the car...

I'm after approx 300awkw for my first stage of mods as I can't afford to do internals yet. I've got a cat back exhaust but everything else is stock. I bought a boost controller yesterday and am waiting for that to arrive and am just about to order a power fc and the dumps/front kit but would greatly appreciate any opinions on the quality of dump/front kit. I've done a bit of research and everyone seems to say that split dumps are the way to go and to stay away from the hks dumps as they are just too short.

I had this exact Trust front/dump setup on my R34 GTR. I didn't really like it in the end. The quality is fine but its the logistics of using the Trust items which is the painful part.

It makes the engine a bitch to put back in if you fit them while the engine is out. If you're going to track the car, pulling the engine out to fit baffles in the sump is almost mandatory.

It comes too close to the firewall and you lose your aircon rubber outlet hose because it touches.

They make changing O2 sensors next to impossible on the car.

On my current GTR i've decided to ditch the whole split pipe idea and have got Tomei dumps. The quality on the Tomei items is an order of magnitude better than the Trust pipes. If you're only going for 300kw then split pipes aren't going to make much of a difference in my opinion.

As for your original question - you need the R34 GTR one without the exhaust temp sensor bung (11920301 BNR34) since you have a non-vspec. I bought the wrong ones originally and had to pay $40 to get the sensor bung welded on mine. Oh wells.

If you do buy these - my advice is to exhaust wrap the whole lot. The temps on the track can get really high back there.

they are quite simply the best front and dump combination available for power extraction (up to 470+rwkw with T618z in the past), i have used them alot and they work better than both HKS and TOMEI equivalents... there are a few tricks to living with them but the results are well worth it.

Cheers for the input guys.

I probably should start a new thread but what the hell... To complete my breathing mods I'd like to put in some pods and was looking at the apexi super suction kit but I'm not sure which one to get as there is the standard one and the z32 version. I guess my question is in future when I have more power and I'm required to replace my AFM's can I just buy the standard super suction kit and put nismo AFM's in later or would I have to get the z32 version??? I'm trying to avoid upgrading the AFM's straight away as they're quite expensive and not necessary with the current power output.

BTW I'm going to go ahead and get the trust dump/front kit...

Dont forget to buy exhaust wrap then!

If you only want 300kw then you can leave your standard AFM's and buy the normal Apexi pods. Even if you decide to upgrade later you can buy Nismo AFM's and keep the same Apexi pods.

To be honest though, I had more than 300awkw and used the standard airbox and standard AFM's on my 34 GTR and was not running into problems.

Yes my AFM's maxed out but a competent tuner can work around it. Probably less than ideal but it works.

on a related topic... :D anyone used the hks dumps / front pipe on gtr ?? i was looking at getting them

Lots of people do. It's a fairly common choice.

They are really nicely built and lots of people make good power on them. What else do you want to know?

So is the advantage of getting the super suction kit over the power intake the fact that the super suction uses a hard pipe where as the power intake uses the existing stock pipe??? Sorry bout all the noob questions but I just don't want to get it wrong...

Where could I get some exhaust wrap from. I live in the N.T. and we don't have the facilities and resources that larger cities have.

Be careful when ordering the Apexi super suction kit as i have ordered mine from nengun in August and i still haven't received it!! They said Apexi has gone bankrupt and are taking their sweet arse time

I hope they don't take that long with my power fc cos I just ordered it yesterday! Would greenline have the same issues as nengun as they just order on demand direct from apexi?

      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.

      Skyline v36 350GT sedan hunting on idle

      By Robot · Posted

      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.
