Hey guys, I purchased my N/A R33gts25 over the weekend and i'm firstly looking to change the stock exhaust/muffler... I've done a bit of searching around the forums and reading... But still a little unclear on some things...

I'm not interested in power modifications ( but don't want to lose power ) as I'm on my P's and it isn't worth the hassle with the new restrictions... i'm just after a nice drive with a nice sound output. That being, nothing too loud that gives you a head ache... just something quiet that kicks in a bit when you give it a nudge...

Specifically on sound, something that has the stock sound of the twins im using at the moment ( that ferrari'ish sound lol ) with a little bit more depth would be awesome... Pretty sure most of you know the sound i'm talking about.. i'll try get a sound file of my current exhaust..

So, should i be searching around for something like this http://www.autobarn.com.au/default.asp ( a complete system )

Or should i just look around for mufflers?

Any help is greatly appreciated :P

if you want a really nice sounding exhaust that is not loud, get a "remus" or a "hi-tech" system. be prepared to pay for it though

They probably wont fit a skyline mate, unless they are specifically for your model dont bother. go order some king springs, or k macs like i did, and then i got pedders shocks to go with it. Do it right, do it once.

just took a pic anyway ( what size are your springs? )

Bit hard to tell if they would fit by pictures, you actually need the code number and ring up king springs and ask what car theyre designed to fit... most likly if they arn't skyline they wont fit as they wont sit in the bottom and top of the strut properly.

Mine are 3.75" lowered kmac's.... they are a much wire and thicker spring by the looks of it. Though bit hard to tell by the picture

I'm also looking around for some new wheels n rims.. should i be looking for a certain size? offset etc?

Also...I've been looking around some of the links on here at places that sell some wheels etc like garage 13.. do yuo guys know of any other places that stock a lot of new and used wheels n rims?

not that I know of. cheapest way to get one is to convince someone who has an N/A who's turboing their car and has aftermarket extractors to sell em to you :)

(and no, I'm not turboing my car)

here's the webpage for it:

http://www.fujitsubo.co.jp/mc-prod/psrs-v.php3?id=00000086

here's one at yahoo for an R33 GTS25

http://page13.auctions.yahoo.co.jp/jp/auction/r19118868

only $1300 :D The reason they're exxy is because their custom made items, ie you place the order and they make one for you.

I've got some pics of it on my car, I'll see if I can dig em up.

If its too big, yes, you will lose power as you still need some decent backpressure on N/A's. However there's also no point fitting a high flow cat back exhaust when your extractors don't flow for shit. Your system's only as good as its smallest bottleneck.

extractors are worth doing. if you do them with a cat back exhuast then you get the best gains. pipe sizing for N/As are pretty much rb20e/de 2.25" and rb25de is 2.5" that is mandrel bent.

when i put my rb30de in i will keep my current 2.5" mandrel bent exhuast that i currently have on my rb20e. its far to big to be good for any low down power

    • I was using the wiring diagram I have So 12.74V is coming into the rear Fuel Pump relay as I measured.  When I turn the key to ON im getting 0.6V to the Fuel Pump plug; which i assume is backfeed voltage and doesnt include the 12V from ignition power.  The rear relay is working and being triggered.  From the diagram I clearly see the rear relay 80 = Rear Relay going into the Body/H loom (R-27) 27 = Fuel Pump plug going into the Body/H loom (T-20) 40 = Short Connector (R-27) I'm reading 12.74V on the blue/black wire which is the power for the Fuel Pump   From this diagram I can see the Ignition relay goes into the front and up to the ignition  2 = Fuel Pump Relay <1M> (R-27) 37 = ING Relay <1M> I started from the pump using this reference Which the way I read it (referencing Nissan wiring color codes) is: Pin Wire Color Function 1 B/P (Black/Pink) Ground 2 L/W (Blue/White)        ECU Trigger 3 SB (Sky Blue) Fuel Pump 5 L/B (Blue/Black) 12V Constant Tested SB to SB on Fuel Pump for continuity - confirmed Tested negative on Fuel Pump to 12V battery and L/B - confirmed 12V Pulled the relay putting 12V between Pin 1 & 2 and testing continuity on Pin 3 & 4 - confirmed relay   So that has me looking at this part of the circuit to understand whats happening here...and im still confused. From best I can tell; the disconnect is back to my previous diagram; between Ignition Relay and Fuel Pump Relay...which yet again; afaik is where the immobiliser should.    Thats what I was trying to explain to GTSboy; im not trying to fix it myself; yet I seem to have to get a Masters in Electrical Engineering (while im busy doing my actual job of DevOps & Cloud Engineering) somehow.  I just wanted more expert opinions; or more so that what I tested is correct and proves it to something around that area; to go back to the alarm tech (for a 3rd time) that he needs to fix it. He keeps telling me its not the alarm. He lives on the complete other side of the city so i understand not wanting to make a trip but as I said before if its the alarm it should be up to him to fix it. But he's adament its not; even though I pointed out the FP was immobilised through the original alarm. To my mind; it seems that the ECU is sending the signal; but the ignition is not getting 12V down the line.       
    • Maybe also really stiffly sprung track cars. Get the inside wheel up in a corner and all the fun stops. Also me sometimes (rarely) when I have to stand on the brake to convince the diff to drive the wheel that is still on the ground when I'm trying to diagonally get over severe driveway entrance, etc.
    • I feel like I'm missing something. You had an authorised installer come out and install a new alarm. Post install the car doesn't start, and you aren't getting the installer back to fix what they did wrong?
    • So either way it is gearbox out and look what is wrong?  I know about the input shaft bearing. Even before swap/new clutch the it sounded exactly like this: So is that inout shaft bearing or the other was installed backwards?  And can some please tell me the part number for that input shaft bearing? The gearbox is small box from R34 N/A and number is FS5W71C. Thank you  
    • I am yet to see anyone ever regret a quaife or helical. ...other than drifting/skidpan duties. I kind of want to upgrade my factory helical with a Quaife (but really it's not ultimately that different, and is a MASSIVE UNDERTAKING), that's how good the hype is about them, that I want to try them 'just to see'
