I have a 1997 series 1 Stagea RS4. i have been using the search buttons but cant see anything recent for tuning a series 1 but plenty for a series 2. i have the standard car with just a HKS panel filter (not installed yet) and am wanting to get the power up to around 200 awkw and was wondering what parts would do the job?

More than you might think! How much money do you want to spend?

Firstly an 80mm (three inch) exhaust from the turbo back - I prefer the split dump over the bellmouth.

Second an upgraded intercooler. A series 2 or GTT smic will do it but if you think you are going to want more power later you might as well get a return pipe front mount.

Thirdly to make a genuine 200awkw with an automatic awd Stagea you will need a better turbo -e.g. your stocker rebuilt by Hypergear or GCG

The most difficult part with an S1 is finding a way to tune it. I would suggest a Greddy E-manage.

A decent electronic boost controller would be nice .

This should get you 200 -220awkw

And finally you should probably invest in a new fuel pump (e.g. Walbro) as although the stocker may do it is quite old by now and you don't want to be caught out when it packs up.

Also change your brake fluid to say Motul RBF600 get some decent pads and a 24mm solid rear sway bar!

(I'm assuming you already have some decent tyres)

The above post is spot on

Once you start spending money the power goal of a SAFE 200awkw is the same for 250awkw

Set your goal higher, because 200awkw is not enough

hahaha niether is 250kw hey darrin :/ i also agree with kiwi except i wouldn't bother with a S2/R34 side mount intercooler, i don't think they are as good as some people say they are. i noticed heaps of heat soak with mine after a bit of spirited driving. go for a front mount, you can get them in different sizes so you will easily find something that fits the nose of a stagea. you can also get them in turnflow style so all the pipes meet up with your stock ones. the only other thing i'd add to what has already been said is get the auto looked at, a shift kit is a must when running more than stock power.

Sorry Shetlander to steal a bit of your post,but it's a good chance to ask...

So,you can get 200 awkw on stock injectors and pump?(apart for the issue of the age of the last)What about Z32 AFM,is it necesary ?or the stock could be ok ,let's say up to 220?

Edited by southern_tango

Freddy, 220-230kw is the max (safety wise) that you will get out of the stock AFM and injectors. Of course, there will be slight variances as per usual with different dyno's. Pushing injector duty cycle % combined with tuning past the AFM is not what you really want.

It would also be a good idea to replace your fuel pump if you're thinking about mods. The stocker would be a bit tired after over a decade of use.

    • Put a fuel pressure gauge on it. Replace the turbos. Probably completely separate issues.
    • What copper washer do you guys use on the bleeder bolts? The existing one I have I had no idea where to find it in a local store, I did buy some online but that are only 1mm thick whereas my old one is 2mm+ thick and when I put the new washer out and squeeze the top radiator hose I can hear a bit of air but not with the old one. Does this matter? The new one doesn't leak, but the inner diameter is a bit loose whereas the old one threads on the bolt.
    • Howdy all, after being out a few weeks ago on a spirited drive in my GTR I have 2 issues that oddly have appeared at the same time. Whilst accelerating quickly through the gears all of a sudden i’ve lost power at the top of third gear (below redline around 6000rpm) for no obvious reason.    From that point onwards the car has been running rich on idle, won’t really rev under load without a ton of black smoke and the odd backfire, and dying as a pull up to a set of lights unless I keep the revs up around 1500rpm. In addition when shutting down the car that same night (I was 10 minutes from home) I noticed one of the turbos was significantly noisy on wind down when shutting off the engine. After letting the car cool down overnight it starts up fine, although once it gets to temp the revs start to creep up and down, the exhaust is darker than it should be and it also sounds like it’s running rich (fat note) I’ve put a new set of plugs in it - no change, the old plugs all seemed OK with two of them being somewhat richer/fueled up than the other 3 with 1 being borderline. I’ve smoked tested the intake system via the front of the Turbos, found a split vacuum hose going to the factory boost gauge sender, which I have since replaced.  Also found another leak on the gasket coming off the rear turbo outlet, have also replaced this. After fixing both of these leaks - still have the running rich issue. I’ve also tried another pair of AFM’s - no change here After pulling off the front turbo intake pipes, there is obvious shaft play in the front turbo, which now hisses loudly on light revvs although I can’t see why this would make the car run funny even under idle. I’m curious to know why it’s running rich before I potentially replace/rebuild turbos. The car is completely stock <50,000kms  other than an exhaust. Oil and coolant are all clear. I haven’t bothered with coil packs as it looks like they won’t be the issue due to condition of the plugs. Any help appreciated as I cry myself to sleep!
    • No probs at all. I used to love trying to dig up obscure info for those in need where possible going back 20+ years on SAU.  I did have another look and couldn't come up with any closer match. I'm leaning towards those skirts in your first pic are custom fitments, cut down/extended or from another car entirely and modded to fit an R34 sedan. I would've thought someone in Japan had them and taken a photo at some stage over the last 2 decades but there's nothing. Someone out there must know surely.
