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.

      Got this r31 silhouette flood car to rebuild.

      By 25RBGT · Posted

      So we have most the interior back in, and for the first time with one OEM speaker hooked up. The 31 is running, driving and now tunes!!! Hahaha yet another step for the sub that sat 10m under for two weeks!!! unbelievable really 👌 lots of love work and not giving up on her. Seen so many youngsters part way less, and in way better condition. I’m stubborn, thinking another problem is just a hurdle to overcome, One at a time. IMG_9277.mov

      That is correct. I'm using a modified ABS ring and a ZF speed sensor on my rear diff for speed input. I'm running a Haltech ecu.

      R32 GTST - 600KW+ RB28/CD009 Build

      By TurboTapin · Posted

      Been busy with the newborn. We originally thought we were going to go for a third, but we're good with two lol. He's starting to actually sleep now so I've had some energy to work on the car. It's been parked away in the garage since late November due to winter.  I went ahead and redid all my head oil drains. I originally had my front and rear head drain going into the same pipe but have since split them up. I also added an Ethanol content sensor to get ready to run E85 this summer. Tossed it on my return line. Sensor sits nicely under my intake manifold.    I also have a lot of parts that came in for my rear end. I'll be swapping over to a 3.3 final drive and doing the GK teck anti squat mod. While the rear subframe is off, I'll also change every bushing. We're planning on buying another house soon with the condition that I get at a minimum a 2 door garage, so I'll wait to have more room for this. Now onto the strange things that recently happened... After changing the lower rad hose (It had been sitting in my cabinet for well over a year and was the last hose I had to replace), I let the car idle in the garage to bleed my coolant. After running for a few minutes, it started missing. Got much worst within a minute or two and then stalled and would not restart. My crank sensor decided to crap itself. No damage, no explanation, just died. I went ahead and replaced it with another ZF sensor but the heavier duty stainless model with a shield. Tossed that in and started right up. Has anyone else seen this? I hate when things fail without cause. Luckily this was a blessing in disguise... This lead me to recheck my timing. It seems I may have had a beer or two the last time I had set my TDC angle as I was off exactly 5 degrees... I miscounted a line haha. I was running 5 degrees less then commanded. It's a little embarrassing but helps explain why my dyno operator seemed to think I should be making more then 478rwkws.

      Nah no bearings, just slip fit.  Would be a reasonably challenging but not impossible job to modify it to run bearings but I'm hoping that's not necessary as I may have well built one myself if I end up spending hours modifying it!
