Hi all,

Had my 1997 RSFour on the rollers last week. Just thought Id post up the graph with a list of mods so we could maybe start a cross referance or something to see how eachothers cars are running and with what mods.

As said above mines a 1997 RSFour Mods are as follows:

  • Splitfire Coilpacks
  • HDI Frount Mount
  • Profec B spec II EBC High boost set at about 11psi
  • SAFC2

Was dynoed in RWD (front tailshaft removed)

I had my 98 RS Four S :thumbsup: on the Dyno a week ago for a couple of power runs. It has a GCG Hi flow, CES Racing split dump, high flow cat and a 3in cat back exhaust. According to the guy doing the Dyno it was hitting Boost cut at 14psi.

Good for a starting point I think. At least now I can go from here.. Forgot to mention it was done on an all-wheel drive Dyno.

hey guys here be mine at all 4s and a empty bank account.

tomei cams and gears

forged pistons and rods

n1 oil pump

flowed and balanced

greddy intake

90mm throttle body

gt35r turbo garret

40mm gate to small and restricting my power going bigger soon

front mount

going full 4 inch zorst old zorst to small

tomei 740 injectors sard reg 044 pump

studded block as old block cracked

arp bolts in every thing

tomei head gasket

many other mods to much to list .once i change the gate and zorst wil pay with timing and more of a tune will go 300awk give or take .advan built and tuned .

sorry my pics wont up load will keep trying

Edited by bernardshorty

I do need to post up my graph, and I saw nick post his today too. will update this thread when i post it elsewhere

mine was done on a 4wd dyno, 155kw

power mods are

power fc

12psi boost

turbo back 3" exhaust

splitfires

walbro fuel pump

standard intake, intercooler, injectors, afms etc etc. oh and manual conversion that probably gives me a couple of kw without the slushbox.

sssstagea you need to get a computer and tune asap. the standard computer responds very poorly to mods - 130awkw is not right for a highflow turbo running 14psi....your setup should be good for 170awkw+

looks like all the stageas have good midrange but poor top end compared to a skyline motor - fits with mark's theory that they have small cams compared to 33 gtst. we are going to do some back to back test with r33 series 2 cams shortly.

Comes back to the same 'rich retards' idea that I was getting with mine, I could feel the car pushing against the 'glass wall' because all the timing had been pulled out by the ECU and as soon as the engine neared the redline it was like a switch was flicked somewhere and all the timing came back for a last minute 'kick' before going back into slug mode again. :huh:

pics wont work since site update(lost my old avatar & gallery) added new pics to my gallery inc. dyno but cant upload.

ces s/s split f/dump ces exhaust.

greddy fmic.

mbc 10 psi.

safc neo.

k&n panel filter.

185.4kw front shaft removed.

I can't see your graph. Could you post up the KW please?

I had my 98 RS Four S :3some: on the Dyno a week ago for a couple of power runs. It has a GCG Hi flow, CES Racing split dump, high flow cat and a 3in cat back exhaust. According to the guy doing the Dyno it was hitting Boost cut at 14psi.

How are you regulating your boost? I guess you are on a budget like most of us or else you would have a Power FC or suchlike already but I would recommend getting a Jaycar Independent Electtronic Boost Controller or if you are just bypassing the solenoid reduce the size of the restrictor to lower boost. Mr car made 155AWKW (200bhp) with the stock turbo on 10.5 psi and i would expect to do quite a better with a GCG highflow. Have you still got the standard side mounted intercooler? If you car is a series II then maybe you already have the GTT SMIC otherwise that would be a worthwhile cheap and simple upgrade. There are two or three aftermarket options for the SMIC and I was luck enough to find a cheap second hand Trust one. But maybe first upgrade your fuel supply (pump and regulator) if you haven't already.

hi guys im just wondering if you guys who have put up dyno results of your stags are you running autos or manuals?? and are they s1 engines because the power figures seem to be a bit low for a neo . my 99 S2 RS4 stag with just a 2 1/2 inch exhaust turbosmart boost control , BOV and 5 speed manual with 10 psi ran this post-50654-1220741966_thumb.jpg

Yep your neo has a slightly bigger turbo and possibly different cam timing from my Series I auto which made 155AWKW (see above for chart). But when I install my IEBC etc and give it a tune I expect to get quite close to your figure.

Perhaps someone with access to FAST could compare the part numbers.

Sorry I can't tell you much about my setup due to only owning the car for about 2 months and not knowing anything about Turbo setups. The guy running the Dyno said that it hit boost cut at 14PSI, not sure if this is what it is running at all times. As far as I know it hasn't had anything done to change boost but looking at everything on this site it must have. I need to find someone that can point out any changes to my setup cause I don't know what looks normal and what doesn't. After reading through this site and getting myself confused on aftermaket engine management I ill also need to go to a workshop or speak to someone who can point me in the right directions. Would really love to find out more about if anything else has been done.

Going to the Gympie skidpan day so will talk to some people there and see what they say.

    • Could be. Could also be that they sit around broken more. To be fair, you almost never see one driving around. I see more R chassis GTRs than the Renault ones.
    • Yeah. Nah. This is why I said My bold for my double emphasis. We're not talking about cars tuned to the edge of det here. We're talking about normal cars. Flame propagation speed and the amount of energy required to ignite the fuel are not significant factors when running at 1500-4000 rpm, and medium to light loads, like nearly every car on the road (except twin cab utes which are driven at 6k and 100% load all the time). There is no shortage of ignition energy available in any petrol engine. If there was, we'd all be in deep shit. The calorific value, on a volume basis, is significantly different, between 98 and 91, and that turns up immediately in consumption numbers. You can see the signal easily if you control for the other variables well enough, and/or collect enough stats. As to not seeing any benefit - we had a couple of EF and EL Falcons in the company fleet back in the late 90s and early 2000s. The EEC IV ECU in those things was particularly good at adding in timing as soon as knock headroom improved, which typically came from putting in some 95 or 98. The responsiveness and power improved noticeably, and the fuel consumption dropped considerably, just from going to 95. Less delta from there to 98 - almost not noticeable, compared to the big differences seen between 91 and 95. Way back in the day, when supermarkets first started selling fuel from their own stations, I did thousands of km in FNQ in a small Toyota. I can't remember if it was a Starlet or an early Yaris. Anyway - the supermarket servos were bringing in cheap fuel from Indonesia, and the other servos were still using locally refined gear. The fuel consumption was typically at least 5%, often as much as 8% worse on the Indo shit, presumably because they had a lot more oxygenated component in the brew, and were probably barely meeting the octane spec. Around the same time or maybe a bit later (like 25 years ago), I could tell the difference between Shell 98 and BP 98, and typically preferred to only use Shell then because the Skyline ran so much better on it. Years later I found the realtionship between them had swapped, as a consequence of yet more refinery closures. So I've only used BP 98 since. Although, I must say that I could not fault the odd tank of United 98 that I've run. It's probably the same stuff. It is also very important to remember that these findings are often dependent on region. With most of the refineries in Oz now dead, there's less variability in local stuff, and he majority of our fuels are not even refined here any more anyway. It probably depends more on which SE Asian refinery is currently cheapest to operate.
    • You don't have an R34 service manual for the body do you? Have found plenty for the engine and drivetrain but nothing else
    • If they can dyno them, get them dyno'd, make sure they're not leaking, and if they look okay on the dyno and are performing relatively well, put them in the car.   If they're leaking oil etc, and you feel so inclined, open them up yourself and see what you can do to fix it. The main thing you're trying to do is replace the parts that perish, like seals. You're not attempting to change the valving. You might even be able to find somewhere that has the Tein parts/rebuild kit if you dig hard.
    • Can you also make sure the invoices on the box (And none exist in the boxes) are below our import duty limits... I jest, there's nothing I need to actually purchase and order in. (Unless you can find me a rear diff carrier, brand new, for stupidly cheap, that is for a Toyota Landcruiser, HZJ105R GXL, 2000 year model...)
