Just bought a N/A r33 manual and have some questions.

Regarding the 4 stud wheels.. what wheels fit?

what is the offset and information I need?

what are some other cars with the same pattern?

will s13 and 200sx wheels fit?

Where is the best place to look for second hand wheels?

Could multistud wheels fit?

Also the car has a stock exhaust which i want to make much louder, something like a 2.5 or 3inch exhaust, what will I need?

how much do I need to spend?

Where can i find good second hand exhausts?

Do any other cars/models fit an r33 N/a?

Will a turbo exhaust fit?

When they say cat back does that mean it is including the cat?

Any information will be highly appreciated.

Also yes i have tryed to search and failed to find the info that I need

Thanks,

Nathan

First off, welcome!

As for the 4-stud wheels... my N/A 33 had the 5-stud conversion when I got it, so I can't help you there.

The exhaust however... I can :)

The previous owner of mine put a JASMA 3" mandrel-bent exhaust designed for a high-flowing turbo 33 on there... had just a single resonator and then into two straight-through cannons. It was *very* loud (I loved the note it had!)... certainly well over the legal 90dB. Anyway, eventually I got EPA'd for noise pollution and had to get it replaced. I got a 2.5" system made up from the cat-back, two resonators and no milo-tin exhaust, and that's bang on 90dB. Still roars when you give it some stick, but now I can come home late at night and not wake up all the neighbours! The major difference (apart from the volume of course) however was the power delivery. With the 3" system on, there was not enough backpressure or something... the power (what little power you have on an RB25DE) started to be delivered from around 4000RPM and would pull ll the way to the red-line (about 6800RPM). This meant you really did have to do a fair bit of clutch slipping for sedate city driving, as there just wasn't enough low-down torque. With the 2.5" system now, the power is there much lower... say 1800-2000 RPM, and tapers off around the 6000RPM mark. This certainly makes it much more driveable for a daily.

The 2.5" system, I got made up for a couple of hundred (was about $250-300, but that included the actual EPA testing...), and as much as I loved that deafening roar that would set off car-alarms jsut from driving past, the 2.5" system is much, much better.

Oh, and cat-back generally doesn't include the cat. :)

Thanks for the reply Samon.. is your Jasma exhaust for sale?? :)

anyway I am not to worried about the performance side I'm only interested in the noise, as the N/A is certainly no performance car. Although i definatley do not want to loose any power.

When you say 250-300 is that a full exhaust system? where could i get it done for that price

I dont want to spend more than 300-350, thats why i'm looking at second hand.

If i found a catback exhaust for a r33 turbo, or r32,34 silvia or some other nissans would it be a straight fit?

Also does anyone know rough 1/4mile times or 0-100 times for a r33coupe na manual?

Not from personal exp, but from reading another thread on here some time ago.. 0-100 for na manual was about 4.5 seconds

Ummm... I think you'll find that was for a turbo... my N/A when completely stockers was getting around the 6.0-6.5 sec 0-100, and around 15 sec 1/4 mile. (Measured with a G-Tech Pro... not 100% accurate but pretty damn good!)

Sorry, the old exhaust is sitting in the garage for when I do my turbo conversion :)

Pretty much any exhaust shop should be able to make one up... that was just a mild-steel one with pressed-bends... if you want stainless or mandrel-bends (really overkill for N/A though...) you're gonna have to pay more. Oh, and that's just with a crappy looking piece of 2.5" black pipe coming out of the rear muffler, no tip or anything. I was only interested in a pass on the EPA test!

Any exhaust from an R33 will fit, be it turbo or non-turbo, but liek I said, too big and you will really loose the low-down torque and driveability. And remember... 2.5" pipe through two mufflers is still damn loud! The N/A is much louder as the turbo on the GTSt acts as an extra muffler, filtering and chopping up the sound that leaves the block... everyone I know says that yeah, it's better (i.e. quieter) than the old exhaust, but still damn loud. I can still set off car alarms occasionally :) Get it inside a multistory carpark (i.e. at my work) and people can hear me coming a few levels away... and that's not me giving it stick either! The other advantage is that it doesn't 'drone' like it used to. At 100ks on the freeway there was this horrible drone that would drive you crazy... now, gone.

Seriously, put a 3" exhaust on an N/A 2.5L engine, and you'll regret it.

hey nathan... im kinda on the same boat as you... but i done the turbo conversion so im trying to find 4 stud wheels as well and there isn't much out there... the 3 spoke Advan wheels are pretty nyc if you can find some second hand ones.. there are also LENSO multi stud wheels which also look pretty nice.. i think they are the GF7...

as for exhaust... i have goten my hands on two catback exhaust systems... one is a kakimoto 3-3.5 inch exhaust and the other is a Fujitsubo i think 2.5 inch with a twin outlet.. looks similar to stock but bigger and better flow.. i think i might put the kakimoto one on my car so the Fujitsubo exhaust will be up for sale... if your interested i can take some pics and we can discuss a price... are u in melbourne by any chance? as postage can be a pain... thanks :P

Thanks for all the replies so far guys!

few more questions

So basically i need a 2.5inch exhaust from cat back? when people say 2.5in catback is that including a cannon?

also with the wheels.. what other cars wheels fit??

What do i need to look for when looking for wheels?

all catbacks come with the muffler at the end.. some have a cannon.. if you just want the look of a big cannon sticking out the end of ur car then jst go to any exhaust shop and they will weld you a cannon onto a piece of steel and onto your cat... cheap around 300 buks but they can be loud and drony...

here are pics of the exact same exhaust i will have for sale.. found these pics from an old for sale thread... my exhaust is the same as this...Fujitsubo, a quality japanese brand.. twin 2.5 inch outlets.. and two mufflers...

thanks

      Next on the to-do list was an oil and filter change. Nothing exciting to add here except the oil filter is in a really stupid place (facing the engine mount/subframe/steering rack). GReddy do a relocation kit which puts it towards the gearbox, I would have preferred towards the front but there's obviously a lot more stuff there. Something I'll have to look at for the next service perhaps. First time using Valvoline oil, although I can't see it being any different to most other brands Nice... The oil filter location... At least the subframe wont rust any time soon I picked up a genuine fuel filter, this is part of the fuel pump assembly inside the fuel tank. Access can be found underneath the rear seat, you'll see this triangular cover Remove the 3x plastic 10mm nuts and lift the cover up, pushing the rubber grommet through The yellow fuel line clips push out in opposite directions, remove these completely. The two moulded fuel lines can now pull upwards to disconnect, along with the wire electrical plug. There's 8x 8mm bolts that secure the black retaining ring. The fuel pump assembly is now ready to lift out. Be mindful of the fuel hose on the side, the hose clamp on mine was catching the hose preventing it from lifting up The fuel pump/filter has an upper and lower section held on by 4 pressure clips. These did take a little bit of force, it sounded like the plastic tabs were going to break but they didn't (don't worry!) The lower section helps mount the fuel pump, there's a circular rubber gasket/grommet/seal thing on the bottom where the sock is. Undo the hose clip on the short fuel hose on the side to disconnect it from the 3 way distribution pipe to be able to lift the upper half away. Don't forget to unplug the fuel pump too! There's a few rubber O rings that will need transferring to the new filter housing, I show these in the video at the bottom of this write up. Reassembly is the reverse Here's a photo of the new filter installed, you'll be able to see where the tabs are more clearing against the yellow OEM plastic Once the assembly is re-installed, I turned the engine over a few times to help build up fuel pressure. I did panic when the car stopped turning over but I could hear the fuel pump making a noise. It eventually started and has been fine since. Found my 'lucky' coin underneath the rear seat too The Youtube video can be seen here: https://www.youtube.com/watch?v=uLJ65pmQt44&t=6s

      It was picked up on the MOT/Inspection that the offside front wheel bearing had excessive play along with the ball joint. It made sense to do both sides so I sourced a pair of spare IS200 hubs to do the swap. Unfortunately I don't have any photos of the strip down but here's a quick run down. On the back of the hub is a large circular dust cover, using a flat head screw driver and a mallet I prised it off. Underneath will reveal a 32mm hub nut (impact gun recommended). With the hub nut removed the ABS ring can be removed (I ended up using a magnetic pick up tool to help). Next up is to remove the stub axle, this was a little trickier due to limited tools. I tried a 3 leg puller but the gap between the hub and stub axle wasn't enough for the legs to get in and under. Next option was a lump hammer and someone pulling the stub axle at the same time. After a few heavy hits it released. The lower bearing race had seized itself onto the stub axle, which was fine because I was replacing them anyway. With the upper bearing race removed and the grease cleaned off they looked like this The left one looked pristine inside but gave us the most trouble. The right one had some surface rust but came apart in a single hit, figure that out?! I got a local garage to press the new wheel bearings in, reassemble was the opposite and didn't take long at all. Removing the hub itself was simple. Starting with removing the brake caliper, 2x 14mm bolts for the caliper slider and 2x 19mm? for the carrier > hub bolts. I used a cable tie to secure the caliper to the upper arm so it was out of the way, there's a 10mm bolt securing the ABS sensor on. With the brake disc removed from the hub next are the three castle nuts for the upper and lower ball joints and track rod end. Two of these had their own R clip and one split pin. A few hits with the hammer and they're released (I left the castle nuts on by a couple of turns), the track rod ends gave me the most grief and I may have nipped the boots (oops). Fitting is the reversal and is very quick and easy to do. The lower ball joints are held onto the hub by 2x 17mm bolts. The castle nut did increase in socket size to 22mm from memory (this may vary from supplier) The two front tyres weren't in great condition, so I had those replaced with some budget tyres for the time being. I'll be replacing the wheels and tyres in the future, this was to get me on the road without the worry of the police hassling me.

      RB25DE NEO with Haltech ECU

      By Haggerty · Posted

      Yep, the closest base tune available was for the GTT, I went with that and made all the logical changes I could find to convert it to Naturally Aspirated. It will rev fine in Neutral to redline but it will be cutting nearly 50% fuel the whole way.  If I let it tune the fuel map to start with that much less fuel it wont run right and has a hard time applying corrections.  These 50% cuts are with a fuel map already about half of what the GTT tune had.  I was having a whole lot of bogging when applying any throttle but seem to have fixed that for no load situations with very aggressive transient throttle settings. I made the corrections to my injectors with data I found for them online, FBCJC100 flowing 306cc.  I'll have to look to see if I can find the Cam section. I have the Bosch 4.9 from Haltech. My manifold pressure when watching it live is always in -5.9 psi/inHg

      Leak from Tokico BM50 Brake Master Cylinder

      By brillo · Posted

      Hi My Tokico BM50 Brake master cylinder has a leak from the hole between the two outlets (M10x1) for brake pipes, I have attached a photo. Can anyone tell me what that hole is and what has failed to allow brake fluid to escape from it, I have looked on line and asked questions on UK forums but can not find the answer, if anyone can enlighten me I would be most grateful.

      Cas issue

      It will be a software setting. I don't believe many on here ever used AEM. And they're now a discontinued product,that's really hard to find any easy answers on. If it were Link or Haltech, someone would be able to just send you a ECU file though.
