Hi guys;

Been reading the power thread and seems like all of the R32s with r33 turbo upgrades are getting 190-210 rwkw, I got a tune done today at Sam (Dr Drift), first run we got 116kw after fixing a few small boost leaks etc. After that we found the fuel pump was rooted so replaced that with a Walbro, had a dr drift chip which got retuned. Turned the boost on 15 pounds, played with timing and final figure came out at 159kw. Car mods include 3 inch exhaust (stock dump / CAT). R33 turbo, boost controller and yellow jackets coil pack (and now walbro fuel pump).

Just wondering where the power loss could be? Or am I confusing between normal kw and rwkw? Do all dyno's measure rwkw? Sam said skyline's normally make around 100 rwkw? Are those 200ish figures with minimal mods the same figure as rwkw (100 stock?)

Sorry if some of the questions are noobish, just thought I'd clarify :D

btw - not like Sam doesn't already have enough plugs, he's the best mechanic I've dealt with so far - and I've gone to a few. Well worth the 1.5 hours each way I travelled :D

My car with the same mods as made just over 190 rwkw

Stock with exhaust and cooler and 12psi and stock turbo it made 150rwkw mate .

U may have a restriction somewhere

Try dropping the cat and see if it's still good and not collapsed ?

Do a compression test ur motor may just be worn out

Is ur car automatic?

Autos will have less power due to power loss through more transmission

If its manual how old is the clutch

There are a few places to start

So you picked up nearly 50rwkw from a tune and some boost...

And you still have a stock cat/dump as you've stated. If you swap those out you might make another 10-15rwkw.

Sounds about right to me. Results in the dyno thread will have proper dumps and hiflow cats etc.

Hmm ok - I might just be expecting too much also :D clutch is fairly new and CAT was put in 2 months ago so that will be fine. Next on my list is the dump and a bigger CAT though - guess different dyno's make different figures also though. Motor is in tip top condition!

P.S: Car is Manual

Does FMIC really show gains? I thought it was more for the wank factor unless you're running numbers over 220 (from what i read on the forums). I don't have one. I haven't driven it properly yet thanks to Melbourne weather (you know what I mean if you're here :D) but it drives a LOT smoother in the lower revs and power delivery is much smoother.

Not wank factor more fact. Bigger intercooler has more area to cool the charged air witch in turn gains slight power overall, due to been 10 times the size of a factory side mount. Buy a cooler kit of just jap.

They are cheap and that will have you on your way to be making more power.

From what I have seen on just jap they have some fair priced coolers.

Im sure your turner will be able to push a little more out of it once you get one.

I would also suggest getting rid of the stock front/dump pipe.

Just get a nice bellmouth pipe made up or purchase one.

Also don't buy a split pipe they seem to be a hit and miss

just so you know - getting a GTR cooler then getting someone to make up custom pipes to fit a GTST will cost same or maybe more than getting a kit of the likes of just jap.

And you are in melbourne so will be arse fisted if you cut a hole in your chassis to get the FMIC piping to go through.

If you want a FMIC, you will need a "return flow" type cooler which uses the stock piping and holes - Just jap have these, Blitz also makes them.

I have an ARC return flow which will go up for sale in th enext couple of months.

Another thing to consider is an R34 GTT side mount intercooler - but this also requires mods to one of the end tanks to fit an R32 GTST.

Out of the 2 RB20 cars I've had on the dyno over the year my results were..

152rwkw - untuned RB20 with RB25 turbo + 12psi

162rwkw - Nistune, stock turbo, 16psi

Some people will tell you you need a tune if you put new oil in.

The truth is that any performance mod will benefit from a tune, but changing exhaust and cooler and filter will give you more power but generally the car will run rich so a tune will give you MORE power and better fuel economy.

Personally I wouldn't bother with a tune a with those mods.

    • Thought I would get some advice from others on this situation.    Relevant info: R33 GTS25t Link G4x ECU Walbro 255LPH w/ OEM FP Relay (No relay mod) Scenario: I accidentally messed up my old AVS S5 (rev.1) at the start of the year and the cars been immobilised. Also the siren BBU has completely failed; so I decided to upgrade it.  I got a newer AVS S5 (rev.2?) installed on Friday. The guy removed the old one and its immobilisers. Tried to start it; the car cranks but doesnt start.  The new one was installed and all the alarm functions seem to be working as they should; still wouldn't start Went to bed; got up on Friday morning and decided to have a look into the no start problem. Found the car completely dead.  Charged the battery; plugged it back in and found the brake lights were stuck on.  Unplugging the brake pedal switch the lights turn off. Plug it back in and theyre stuck on again. I tested the switch (continuity test and resistance); all looks good (0-1kohm).  On talking to AVS; found its because of the rubber stopper on the brake pedal; sure enough the middle of it is missing so have ordered a new one. One of those wear items; which was confusing what was going on However when I try unplugging the STOP Light fuses (under the dash and under the hood) the brake light still stays on. Should those fuses not cut the brake light circuit?  I then checked the ECU; FP Speed Error.  Testing the pump again; I can hear the relay clicking every time I switch it to ON. I unplugged the pump and put the multimeter across the plug. No continuity; im seeing 0.6V (ECU signal?) and when it switches the relay I think its like 20mA or 200mA). Not seeing 12.4V / 7-9A. As far as I know; the Fuel Pump was wired through one of the immobiliser relays on the old alarm.  He pulled some thick gauged harness out with the old alarm wiring; which looks to me like it was to bridge connections into the immobilisers? Before it got immobilised it was running just fine.  Im at a loss to why the FP is getting no voltage; I thought maybe the FP was faulty (even though I havent even done 50km on the new pump) but no voltage at the harness plug.  Questions: Could it be he didnt reconnect the fuel pump when testing it after the old alarm removal (before installing the new alarm)?  Is this a case of bridging to the brake lights instead of the fuel pump circuit? It's a bit beyond me as I dont do a lot with electrical; so have tried my best to diagnose what I think seems to make sense.  Seeking advice if theres for sure an issue with the alarm install to get him back here; or if I do infact, need an auto electrician to diagnose it. 
    • Then, shorten them by 1cm, drop the car back down and have a visual look (or even better, use a spirit level across the wheel to see if you have less camber than before. You still want something like 1.5 for road use. Alternatively, if you have adjustable rear ride height (I assume you do if you have extreme camber wear), raise the suspension back to standard height until you can get it all aligned properly. Finally, keep in mind that wear on the inside of the tyre can be for incorrect toe, not just camber
    • I know I have to get a wheel alignment but until then I just need to bring the rear tyres in a bit they're wearing to the belt on the inside and brand new on the outside edge. I did shorten the arms a bit but got it wrong now after a few klms the Slip and VDC lights come on. I'd just like to get it to a point where I can drive for another week or two before getting an alignment. I've had to pay a lot of other stuff recently so doing it myself is my only option 
    • You just need a wheel alignment after, so just set them to the same as current and drive to the shop. As there are 2 upper links it may also be worth adding adjustable upper front links at the same time; these reduce bump steer when you move the camber (note that setting those correctly takes a lot longer as you have to recheck the camber at each length of the toe arm, through a range of movement, so you could just ignore that unless the handling becomes unpredictable)
    • I got adjustable after market rear camber arm to replace the stock one's because got sick of having to buy new rear tyres every few months. Can anyone please let me know what the best adjustment length would be. I don't have the old ones anymore to get measurements. I'm guessing the stock measurement minus a few mm would do it. Please any help on replacing them would be fantastic I've watched the YouTube clips but no-one talks about how long to set the camber arm to.
