I should be receiving my very first stagea mid to end of this week hopefully if all works out well. a 1997 rs four v dayz (my guessing from what i've read on this forum) with leather interior rb25det. The car is 100% stock and was wondering what is the first thing I should do to increase the power/appeal/feel of the car would be? I've been looking around and was thinking of a few possibilities

1) a whole exhaust, going with a low mount exhaust manifold, 3" dump pipe, 3" highflow cat, twin front pipe, and 3" back from there with 2 mufflers of some sort. My brother is a stainless steel welder so most likely will be done by him (from the front pipe back).

2) a set of g4 stagea coilovers from justjap.com , Haven't been able to find any other stagea coilover parts in australia (not really willing to buy over seas)

3) some 18's haven't really decided on what look I want or what goes with the car really yet though

4) Fmic and bov for that mean look (it's more of a last choice at the moment no real point with a stock turbo and such)

Apart from those I am looking for a r32 gtst waste gate actuator so I can run 10psi constant (do I need a boost controller of any sort for this mod?) I've been looking around and was wondering when the stock fuel/boost cut occurs on the stock ecu of a stock stagea?

Thanks if any of you's read my ramblings

1) Please dont take this as a personal attack, but before posting up a thread like this please do a search there are numerous threads exactly like this with all the same questions asked and answered.

2) what state do you live in?

3) By going for coil overs i think you will end up finding that you will have a very harsh ride (what i mean by this is that it really will feel more like a track car rather than a well set up street car.

Try the SydneyKid suspension setup:http://www.skylinesaustralia.com/forums/index.php?showtopic=85592

4) With the exhaust i can only recommend the BOS Stainless Steel Split dump and front which lucky for us is exactly the same as an R33 and for a high flow cat i could only recommend the Catco cat 4" body, both of these items can be found in this link: http://www.skylinesaustralia.com/forums/in...howtopic=152367

For the cat back im not really sure what you are after i have a fujitsubo cat back at the moment very very nice and quiet exhaust and flows really well, its not my cup of tea though cause its not loud enough for me, so i just purchased a Trust PE 2 cat back from japan, but i cant comment on it yet as i have not recieved it yet.

5) In my personal opinion FMIC is one of the most important mods for performance wether you have a stock turbo or not it creates a hell of a lott more power. I have an ARC crossflow cooler which can handle around 250kw at wheels, i cannot recommend this high enough because you dont have to cut any holes in your chassis as it retains the stock cooler pipes and also retains stock air box, which makes it a fully leagal setup perfect for more than 200 all wheel kw.

Sorry I should of thought about what I was posting before I did, searched a little but couldn't really work out what I was searching for at that second.

With the exaust i've been driving a subaru liberty 2.2 litre with a straight 2.5" exhaust with only a barely muffled cannon (loudest most drowny thing ever) I love the sound of the rb series motor but how well does it hold up with an automatic (longer gear ratios) does it drown?

Would it be a better idea to leave the fmic until I get into some actually ecu tuning (read some not so good stories of small problems arrising from fmic's)? As this will be a pretty slow project as i'm only an apprentice. I'll deffinately have a look at the arc cooler, I was thinking of going with a front facing intake though as the idea of the intake pipe going straight over the valve cover just seems stupid to me (mightn't do anything performance wise but was hoping would reduce turbo lag from fmic.)

Yeah I know coilovers may give a much harsher ride but I was hoping to get onto the track with it a bit when I come into some money to fix it if things go astray. The g4's are rebuildable and come with different rated springs apon request at no extra cost.

The Fuji exhaust i have at the moment does not drone at all, you cant even hear it from inside the car, at and does still sound quit nice but you have to be farly close to the exhaust to hear it as it is super quiet.

I have had my front mount on for a long time now and never had a problem with it and i still have not had it tuned.

My personal opinion is that a front facing plenum is an absolute waste of money, all fmic kits you buy will be made with all the pipes designed to be fitted with a standard plenum, so it will cost you to have these pipes adjusted to suite and it will cost money to have the plenum fitted plus the cost of the plenum itself.

The sydneykid suspesion setup would also be fine for the odd track day, in my opinion it is a much better setup rather than the G4 coilovers.

Im not in anyway trying to push in any direction just giving my opinion.

What sort of apprentice are you?

Simon and Harold. Leave the PE2 well enough alone. Its nice for the fit but the rear can is a massive power robber. I picked up 20rwkw by changing the rear can to a "drift" item. Hard to believe but true.

      Pops when backing off throttle, rough-ish sound through rev range.

      By GTSBoy · Posted

      Keeping in mind that I am currently getting flat 10 L/100km on my RB25DET, which means >>500km/tank. I would test this car for vacuum leaks, check codes and AFM signal with NissDataScan as D says, check plugs, do a compression check while they are out.

      By Duncan · Posted

      It is hard to be specific half way across the world...but it *seems* like it might have a minor issue. Is the idle stable and does it rev smoothly? I would not expect any pops out of what I am assuming is a standard ECU, standard tune, standard exhaust. You can use Nissan Data Scan to find out exactly what is happening when it runs, the cable/software is reasonably affordable if you are not planning on changing the ECU (which hopefully you are not with an NA skyline) BTW your mileage may not be that far off, these are heavy old tech cars, and being NA might mean you use a heavy foot to keep up with traffic....

      Hey guys! Y'all are the masters so figured I'd check in on a few items here. - My engine sounds ever-so-slightly more raspy than the other NA RB25s I've listened to. It's barely noticeable but definitely a slightly different sound. - When I back off the throttle at high RPM, I will sometimes get a pop out of the exhaust, assuming this can be diagnosed as misfire. Some history on the car: - Had an exhaust leak in auction sheet but was claimed to be fixed by seller (bought from USA importer).  - Car's coil packs and sparks were replaced when it was sold to me, but unsure on what the gap is and whether the coil packs are correct.  - A prior mechanic had misdiagnosed a pilot or throwout bearing sound as LSPI/detonation. Had played with timing a bit, pops/raspy sound of engine just got worse. Got timing reset. - Had failed emissions a few times. First time went in as is, failed. Second time, replaced cat, still failed, running rich as hell. Third time replaced o2 sensor, passed. Car still smells gassy though. - Timing belt and valve cover gasket also replaced.  - Gas mileage is... low. about 350-400K per tank.  Any idea if I'm having any serious issues here or does this all sound like normal old NA RB stuff and I'm fine to drive it with the pops/slightly raspy engine? If it'll help, I can get drop a video of the sound of the engine.

      Looking for a part number for this part here

      By Duncan · Posted

      So....to find any R chassis part number, get your VIN (will be something like ER33-xxxxxx for you) and go to: https://www.amayama.com/en/genuine-catalogs/nissan and enter it. From there you have access to a web version of Nissan's part system, FAST. It is a bit tricky to get used to, so maybe have a shot and post up what you think.  You can also search by general model but note in some cases your car might have different options so VIN is safest.  On diagram 211 I got 14075-75T16 for Connector, Water Hose If I search for part 14053‑21U10 that you posted, that is also a water hose but not the one bolted to the plenum and 14075‑04U00 is the fitting where the water hose goes into the block.

      Duncan's V37.......race car?

      By Duncan · Posted

      Yeah now we are talking I much prefer coolers in the front middle because it lessens the chance of a small bump to a corner stopping the whole event. I was thinking the AT cooler can move out of the radiator, delete the AT/engine coolant interwarmer and mount a separate cooler with a thermoswitch somewhere further back as is common in racing, that would be one thing. Beyond that, the engine oil cooler is an obvious one to move to the wheel arch, potentially one on each side, but unused space is an issue. I did have a earlier pic with the bumper off but it doesn't show how busy the corners are: DS is full of the auto driving sensors and PS is totally fully of windscreen washer fluid reservoir But ultimately I was hoping to keep the AC, and the water/air heat exchanger is fundamental so it is not just the radiator that needs to be in front BTW here's airflow to the rad as it ran at the track (one horn is gone now and I'll remove the lights next time):
