Hello,

I have owned a bone stock 96' 4 door ECR33 with LESS THAN 20K miles for about a year now and I have finally decided to give it some upgrades. I bought a super clean set of R33 GTR wheels for a steal and I have decided to follow a stage 1 guide I have seen floating around on this forum and others. I have found everything I want EXCEPT an exhaust. I want to know what I should run from the trubo allllll the way back. I havent really worked on a car in this manner before so please be specific. Any suggestions? I also want to know what measures I should take to avoid common problems with my engine. I have heard the rb25det has an oil issue but i dont know much about it or other problems. 

Thank you from Okinawa, Japan

Ideally you want a full exhaust.  So you want a nice big dump pipe (off the turbo), big 4" or 5" cat with 200cpi (if you want it to do anything at all) or 100 cpi (if you want it to do almost nothing at all but look pretty legal) or no cat at all if you give no fark and don't mind cleaning the soot off the bumper.  The exhaust should then be 3" or 3.5" with a straight through centre muffler and a big rear muffler.  3" if you future power goals are not super high, 3.5" if you're aiming for lots of power.

There is an entire thread on here (search for "oil control") with hundreds of pages.  Start reading at the beginning, then you can actually skip a lot of it and only read the last 20 pages or so.  You will see posts towards the end guiding you to where the useful summary info starts.

Awesome! Thanks for the advice. Any recommended manufacturers? If you're running this setup what do you have?

And watch out for Japanese brand name exhausts - many of them have 3in inlets and outlets but narrow down to 2 1/2 in just before the outlet.

Thanks for the tip. I'll keep an eye out

I'm only making ~190rwkW, so don't need a super exhaust.  I just have a no-name 3" Jap exhaust (that doesn't have the 2.5" restriction).  If I was to put a new exhaust on my car, to meet some enhanced power making desires, I would not buy an off the shelf "brand name" exhaust.  I would get it made locally to my specs with mufflers of my choosing.

Unlike APR you can go from Stage 1 to Stage 3.5 without the need to retune between stages.

Invest a Link or Haltech or ECU Master get your car running really well, setup closed loop o2 feedback and boost control via  3-port MAC valve.

The stock ECU is the restriction in most cases.

    • I used to hate R31s, and any of the other Nissans that led up to it, and any of the Toyotas with similar styling, because of the boxiness. They were, and remain, childish, simplistic, and generally awful. I appreciate R31s a lot more now, but only the JDM 2 door. The ADM 4 door (and any other 4 door, even if they are unique compared to our local one) can eat a bowl of dicks. The Aussie R31 is also forever tarnished by their association with stereotypical bong clutching Aussie R31 owners of the 90s and early 2000s. I think the Nissans of the 70s (other than 120Y/180B/200B) are far superior looking to the 80s cars. The 240K era Skylines are boss. The same is broadly true of Toyotas. Hondas don't ever register in my thinking, from any era. Mitsus are all horrid shitboxen in any era, and so also don't register. Subarus are always awful, ditto. Daihatsus and Suzukis also don't generally register. They are all invisible. I think the SW20 MR2 looks fiddly. The 3000GT/GTO is like that but way worse. Too many silly plastic barnacles and fiddly gimmicks ruined what could have been a really nice base shape. Kinda-sorta looks like a big heavy ST165 Celica coupe (and I'm not sure if that's a good thing or a bad thing). I think the 180SX is dreadfully bland. It's not bad looking. But it has no excitement to it at all. It's just a liftback coupe thing with no interest in its lines, and bad graphical elements (ie wide expanses of taillight plastic on the rear garnish). The S13 Silvia is a little better - getting closer to R32 shapes. But still....bland. S14? Nope. Don't love it. S15...a little better. Probably a lot better, actually. Benefits from not being like a shrunk in the wash R34 (where the S13 was a shrunk in the wash R32 and the S14 looked like a Pulsar or something else from the stable on Nissan mid 90s horrors). The Z32 was hot as f**k when it came out but hasn't aged as well as the A80. Keep in mind that I think the R33 is the most disgusting looking thing - and out of all the previous cars mentioned is objectively closest to my precious R32. It's just....real bad, almost everywhere you look. And that is down to the majority of what was designed in the 90s being shit. All Nissans from that era look like shit. Most other brands ditto. In that context, the FD absolutely stands out as being by far the best looking car, for reasons already discussed. Going behind the aesthetics, the suspension alone makes it better than almost any other car.  
    • If they just called it the "Mazda Tiffany", it would have been spot on.
    • Yup but for me its the HR ! Cut my teeth on the old holden 6s in the day ! And here's me thinking in the day it was also the 300ZX and the Mitsubishi GT3000 ! All, as well had good lines, but always seemed to need finishing off, style wise.
    • A 180SX has a much better look than a FD. The roofline is far superior being a fastback. It's popups look better. In a world where we all subconsciously add a little bit of low, and wheels of our preference, it's just more handsome than the FD is. The FD just looks 'bubbly' in comparison. It can come down to preference, sure. But "The FD is the BEST looking (on appearances alone) 90's JDM car without question?" Nah. Plenty of questions lol. I could think of 8 cars I think look fundamentally better, and probably a handful of ones that look about on par with a FD. (like say a SW20 MR2) I feel people like/overrate the FD because of it's mythicality/rarity, its rotary and it's unpredictable nature. It probably drives great, you can stuff a ton of tyre under there, has a unique sound, light as hell. I feel that people reading this thinking "YOU CANT RATE A 180 ABOVE A FD BECAUSE A 180 IS A CHEAP DRIFT BUCKET" prove the point about bias as to what the car represents, moreso than how it actually looks.. I feel the 80's boxy/squared off look is becoming better looking due to time, and 90's melted soap bar aesthetics have not aged well. (yet?) And this thread is purely about looks :p
    • A red or yellow S15 wins my vote, Ack that it just scraps in with the 90's cars theme, but they are great looking little sports car Next would be a A80 Supra (pre face lift), whilst the A80 has its own issues, I feel is the best looking larger GT car As for the FD, "I" feel that the reason it triggers me in a non-positve way when looking at one, is like looking at a high maintenance pretty girl who you know is mentally unstable and likely to explode for no apparent reason
