Correct they won't fine you, last year I made the mistake of taking my car over the pits with the cat replacement pipe fitted instead of a cat. I didn't get fined, just had it noted on my work order that a cat converter needed to be fitted.

it all depends how much power you want... spec-m intercooler and the hi-flow cats from just jap are good, but you won't be preparing yourself for huge power.. if you just after a reasonable increase without chasing huge numbers then these are cheap and excellent options.

That is what I'm thinking, for now my immediate target is for around 230/240rwkw, give or take. My ultimate target is up around the 300 mark..

For the exhaust though, don't get the front dump custom. Kermit will even tell you that. Get one of the stainless front dumps Just Jap make. They are pretty cheap and top quality.

Muffler choice is a bit more important than I first thought when I got a muffler for my R33. You need to decide how you want it to sound and how loud you want it to be too. This will determine the shape of the muffler. Important things are that it is a straight through muffler so there is less restriction. If you want it quieter and deeper, get an oval shape muffler. If you want it loud and proud get a cannon.

Hmmm, where did you get your cannon? I've gone around to KYP and I haven't heard back, looking at getting myself either a trust/greddy muffler or a kaki if I can... I'm looking at any importer/workshop that can at least get back to me within a week...

On the front/dump, that is what I was thinking anyways, I remember Kermit telling me that himself..

I have a few mates into 4WDing and they all had this same issue. 3 of them went to "high flow" air filters and they were fine in the city, but caused problems letting crap into the wrong side of the inlet due to the bigger flow rate (coarser mesh) in the pods. Keep the airbox and use a K&N or equivalent panel filter, and ckeep an eye on the "clean" side of your airbox on long runs. You may be very suprised at what they actually let through (especially on the albany and great southern hwys)

Hmmm, maybe a custom airbox could be possible, I've seen the odd few in HPI and the likes... Who would stock them in WA? or could get them in at least??

Couldn't you make an air box? Aluminium, welded into a box, allow the pod filter in, and seal it all up. Or allow put a cover on the bonnet so that it seals when the bonnet it closed, but is open and easily accessed (and visable) when its open?

Might be worth looking at an ARC airbox, much, much better than stock box... as good or better than a pod+airbox setup.

Think there around $450 and are a bolt in replacement.

For the muffler, I got mine from ebay for the R33. For the R34 I've decided to spend a bit more and I have a muffler from a company called SMB. The specialise in exhausts. This one should sound awesome. Its not a cannon, but rather an oval shape. This will keep it slightly quieter with a deeper note :D

Make the custom air box yourself. Thats what I'm doing after I get my front mount. Its pretty easy. There is even a tute on here with a pictures and a drawing with measurements to suit the R34. It looks really good, and its the way I'm going :cool:

Is that an airbox for panel-filter/stock replacement or a box for pod setup???

Can anybody here read Japanese???

Saw this on Nengun corresponding to their latest edition to their intercooler lineup, the LS Spec (Which has succeeded the Spec-M).

Well the difference between no cat and the x-force 3" lo-flow POS, is chalk and cheese. Made my engine doughy and less responsive and the seat of the pants dyno told me it lost a good 30-50hp.

Hey bubba i have full xforce 3"tbe with xforce cat obviously. I noticed that even when i took resonator and silencer off it still sounds f**k all. I am going to put a de cat pipe on there. Do you reckon that will up the performance much and sound wise what would it do?

other mods fmic, ebc, pod, apexi pfc

cheers dude

Well this is what I've decided on thus far..

kakimoto10zmuffler.jpgkakimoto10zmuffler2.jpg

Kakimoto Muffler.

- 3.5" Inlet

- 3.75" Tip

- Stainless

- Canon Type

xfmetalcat.jpg

Catco 3.5 inch cat.

- Stainless

- 3.5" Flanged

- Flows Up To 886CFM

- Gaskets Included

With Kermit to do the zorst for $650 custom...

Now to decide on a suitible Split/Front dump pipe... JJR don't provide these for the R34 GTT.. What are some other options???

As above, I'm also looking into an Spec-LS Trust-Greddy intercooler... Anybody know of someone in Perth that already has them or can get them in by around Chrissie/New years??? Maybe sooner??

Yeah I think losing that xforce cat will increase your performance a bit in terms of responsiveness (made a big difference in my car but I was trying to push 3L exhaust gasses through that shitty cat), with a decat pipe it will sound awesome at revs but maybe a little truck like at idle. More than welcome to have a listen to mine if you want :D

we will be stocking the new greddy cheap fmics when stocks of the mspecs wind up . there really is no difference in quality , there still made in the same china factory , although quality if very good for china.

the catco metal cat is a bit expensive for the minimal gains you get with your proposed setup . my 33 4 door had a full xforce setup , including their cheap hiflow cats and the car made an extra 15hp with the whole exhaust removed . thats really not that bad for a cheap exhaust to only drop 15hp. remember you have to run some sort of exhaust , so what do you stand to gain from a better expensive exhaust system, 7-10 hp maybe ? you could spend the extra 1k your going to pay in much better places

that was with a hks gtrs pulling 330rwhp , perhaps with a massive turbo things would have been more restrictive but thats the same sort of setup your aiming for anyway

Mark... there are not really any options for a split dump for the R34's :(

I've looked into this quite a bit. HKS make some split dumps, but then you also have to buy the front pipe. Being HKS, you pay big money, and its just a damn pipe. I'm just going the bell mouth front dump. The gains to be had with a split dump over a bell mouth setup is not worth the many extra dollars imo. If just jap made a split dump, I would get it as they do a good price, but I spoke to them and they have no plans to make one for the R34 :(

The just jap front dump is about $200 from memory, which is really good. I'm basically doing the same as you. 3" all the way. I've got a different muffler though. It arrived yesterday :D

1: Please Alastair, give us a hoy when the new ones come in, I'm keen as (also, likewise let me know when the R34 Vi-pecs also come in). :D

2: China? I thought all Trust-GReddy stuff was made in Japan??? I thought X-force and the likes were China?? :D

Hmm, so the HKS one isn't a split front dump???

I was thinking of getting one as I'm entertaining he idea of getting a HKS turbo at some stage in the future...

No... HKS is one of the few that do make a split dump, but its rather expensive. Most HKS turbo's require a different dump anyway, so its probably worth just getting a just jap pipe while you're running the stock turbo and then getting the HKS one when you upgrade turbos :huh:

Is the item on Nengun??

    • This. As for your options - I suggest remote mounting the Nissan sensor further away on a length of steel tube. That tube to have a loop in it to handle vibration, etc etc. You will need to either put a tee and a bleed fitting near the sensor, or crack the fitting at the sensor to bleed it full of oil when you first set it up, otherwise you won't get the line filled. But this is a small problem. Just needs enough access to get it done.
    • The time is always correct. Only the date is wrong. It currently thinks it is January 19. Tomorrow it will say it is January 20. The date and time are ( should be ! ) retrieved from the GPS navigation system.
    • Buy yourself a set of easy outs. See if they will get a good bite in and unthread it.   Very very lucky the whole sender didn't let go while on the track and cost you a motor!
    • Well GTSBoy, prepare yourself further. I did a track day with 1/2 a day prep on Friday, inpromptu. The good news is that I got home, and didn't drive the car into a wall. Everything seemed mostly okay. The car was even a little faster than it was last time. I also got to get some good datalog data too. I also noticed a tiny bit of knock which was (luckily?) recorded. All I know is the knock sensors got recalibrated.... and are notorious for false knock. So I don't know if they are too sensitive, not sensitive enough... or some other third option. But I reduced timing anyway. It wasn't every pull through the session either. Think along the lines of -1 degree of timing for say, three instances while at the top of 4th in a 20 minute all-hot-lap session. Unfortunately at the end of session 2... I noticed a little oil. I borrowed some jack stands and a jack and took a look under there, but as is often the case, messing around with it kinda half cleaned it up, it was not conclusive where it was coming from. I decided to give it another go and see how it was. The amount of oil was maybe one/two small drops. I did another 20 minute session and car went well, and I was just starting to get into it and not be terrified of driving on track. I pulled over and checked in the pits and saw this: This is where I called it, packed up and went home as I live ~20 min from the track with a VERY VERY CLOSE EYE on Oil Pressure on the way home. The volume wasn't much but you never know. I checked it today when I had my own space/tools/time to find out what was going on, wanted to clean it up, run the car and see if any of the fittings from around the oil filter were causing it. I have like.. 5 fittings there, so I suspected one was (hopefully?) the culprit. It became immediately apparent as soon as I looked around more closely. 795d266d-a034-4b8c-89c9-d83860f5d00a.mp4       This is the R34 GTT oil sender connected via an adapter to an oil cooler block I have installed which runs AN lines to my cooler (and back). There's also an oil temp sensor on top.  Just after that video, I attempted to unthread the sensor to see if it's loose/worn and it disintegrated in my hand. So yes. I am glad I noticed that oil because it would appear that complete and utter catastrophic engine failure was about 1 second of engine runtime away. I did try to drill the fitting out, and only succeeded in drilling the middle hole much larger and now there's a... smooth hole in there with what looks like a damn sleeve still incredibly tight in there. Not really sure how to proceed from here. My options: 1) Find someone who can remove the stuck fitting, and use a steel adapter so it won't fatigue? (Female BSPT for the R34 sender to 1/8NPT male - HARD to find). IF it isn't possible to remove - Buy a new block ($320) and have someone tap a new 1/8NPT in the top of it ($????) and hope the steel adapter works better. 2) Buy a new block and give up on the OEM pressure sender for the dash entirely, and use the supplied 1/8 NPT for the oil temp sender. Having the oil pressure read 0 in the dash with the warning lamp will give me a lot of anxiety driving around. I do have the actual GM sensor/sender working, but it needs OBD2 as a gauge. If I'm datalogging I don't actually have a readout of what the gauge is currently displaying. 3) Other? Find a new location for the OEM sender? Though I don't know of anywhere that will work. I also don't know if a steel adapter is actually functionally smart here. It's clearly leveraged itself through vibration of the motor and snapped in half. This doesn't seem like a setup a smart person would replicate given the weight of the OEM sender. Still pretty happy being lucky for once and seeing this at the absolute last moment before bye bye motor in a big way, even if an adapter is apparently 6 weeks+ delivery and I have no way to free the current stuck/potentially destroyed threads in the current oil block.
