Okay guys as promised here are the before/after results of some cheap maintenance + the different between a cat-back and a full exhaust. The graph is shown at the bottom.

Spec's:

BEFORE - Green line on the graph

1995 GTS-T Series II

FMIC (Micks Metalcrafts)

2 Stage Boost Controller (7/12 psi)

HKS Pod filter

3" Nismo cat-back

Stock ECU

Stock Turbo

96 RON Fuel

Motul Turbo Oil done 8,000km (Ouch!)

Results:

7psi = 168 rwkw

12psi = 192 rwkw

AFTER (3mths later) - Red line on the graph

FMIC (Micks Metalcrafts)

2 Stage Boost Controller (7/12 psi)

HKS Pod filter

3" Nismo cat-back

Stock ECU

Stock Turbo

* 3" Custom 1 piece Front+Dump Pipe

* 3" Custom Hiflowed Cat

* 98 RON Fuel

* New Ryco Oil Filter

* New Ryco Fuel Filter

* Castrol Magnatec Oil done 2,000km

(Car has not been serviced by a mechanic for atleast 15,000km, Just been doing fluid changes and sheee purrrs)

Results:

7psi = 185 rwkw (Up 17rwkw)

12psi = 203 rwkw (Up 11rwkw)

Conclusion

Well as you can see some cheap maintenance and a proper full exhaust system can make quite abit of difference. The midrange power in my car is 500% better now that I have a proper full 3" exhaust. Some of the benefits I (as a driver) noticed after fitting the exhaust:

* Heaps better midrange power it almost feels like the Turbo is cutting in earlier

* Much more free flowing when you back off the gas it literally just rolls for ever, none of the sudden jerky-ness it just keels going

* No difference in the note/sound of the exhaust from the inside the car

I don't know how my car drove with just the stock standard Nissan exhaust as the previous owner had already fitted the 3" Nismo Cat-Back, but basically from a novice drivers point of view your exhaust is only as good as the weakest link and if you only have a standard front + dump pipe your absolutely kidding yourself. Go and spend the extra $750 like I did and you'll love it to bits.  

I have no idea if the ECU has been re-mapped or has an addon-card. I've taken the kick panel off and everything appears to be stock, oem nissan stamp, no extra doobie-whackys etc. If you see me out and about ask me if you can see my ECU as no doubt you'll know what your looking for to work out if its stock or not coz I really have no idea.

I'm gonna keep throwing small amounts of money at this car (when I workout a new bank I can rob that isn't local) but keeping the Stock Turbo + ECU and really see what I can get out of it. Their have been HEAPS of people say that 200rwkw isn't possible from a stock ECU/Turbo well im going to get more out of this bitch you just watch me. (Hoping 210+)

I plan on changing the HKS Pod to an Apexi filter and also install the f/glass box I have and create an airduct from down on my front bar to feed the engine some much needed cold air. Maybe also 1 of those oil catch can thingy's and urmmm well I dunno i'll keep reading SAU to workout what else can be done.  

If you have any suggestions throw em hear as i'd love to hear your comments.

dyno-203rwkw.jpg

well done!

try a cold air feed down low up to your filter if it makes that power with 12psi of

hot air you will notice the diff str8 away being able to push 13psi max n no pingn,

havent followed ur progress but have u thought of using 98 octane and

advancing your base timing couple degrees? cheaper then a power fc too. lol

what about?

water spray mist on cooler when pressure rises above 10psi? all ads up.

:P

This thread is 2yrs old and alot has changed since then the main thing being that the dyno used for this run appeared to record slightly higher than normal power.

    • Hey guys, Just want some advice on r34 GTT ac system. Since I’ve owned it, the ac compressor, doesn’t matter the set temperature or ambient temperature, runs for around 10 seconds then disengages the clutch, then re-engages everywhere 30 seconds or so and keeps repeating this.    is this normal?   I had it recharged today as it was slightly low and thought it would fix it but still does it. it cools fine in summer even prior to the recharge, except for the usual warmup when stopped or in traffic (still yet to wire overheat fan to on with ac)   any thoughts would be much appreciated 
    • To plug the hole. The engine plant may not have known whether the car it was going into had a gauge or not. It was a long time ago and the integrations might not have been fully modern. Or they might not have cared because the extra inventory and processes to save a few cents on the sender might have cost more anyway. But please tell me you are not still confusing the idea of a pressure gauge sender, and an oil pressure light switch. The switch will be out there. In a separate hole. Probably with only one wire running to it. Running the light.
    • Blower needs to go low on the exhaust side, displacing the AC and PS, which you have to decide whether you want to keep and how and where to relocate if you do. Electric option for PS is, at least, helpful. Sadly, there is no workable 12V electric AC of any value. Whilst the blower is the last compression step before the throttle, and so it might seem a good idea to have it near the inlet manifold (as mentioned above), you probably want it to go through an intercooler first, so, having it on the opposite side of the car facilitates that air flow path. The turbo discharges into the blower, so proximity of the turbo's compressor outlet to the blower's inlet is nice. But then you might want to intercool that too, before boosting it again....which would probably be a ball ache. Routing pipes out to the front and back could be a bit shit. If there was room for (at least) a small (but preferably larger) water to air core on that side, then that would probably be the best approach. I guess a reasonable alternative would be to locate the blower where the alternator is (more or less, associated with the inlet manifold, per Matt's thought), and somehow incorporate a water to air core into the manifold, sort of like they do for modern blown V8s. The big difference here though is that those V8s have only the one throttle (upstream the blower) and only the one compression step (the blower) and no need for too much in the way of bypass/blowoff valves. Whereas in a twin charged 6, you do need to think about one or two bypass valves associated with the 2 compressors and you would prefer to have the intercooling done before the air has to pass through the throttle. You'd like the throttle to work approx the same no matter what the compression is doing. But if it is located in hot air stream before a cooler, then sometimes the air will be real hot, sometimes it will be quite cool, and the throttle mapping/response will be quite different between those two cases. The throttle, if sized for hot air, would be too large for cold conditions. It's all a ball ache.
    • Package SC on exhaust side. Remote mount turbo. Still a fair bit of room when you get creative on the inlet side of the motor too. Especially if you can get really creative with the welding, and effectively build it into the bottom of the inlet manifold. Would definitely take some design work, and some trial and error, to make sure flow works well still! Might be easier to just start with the Nissan March though... All the work is already done for you...
