gtst,

on the subject of computers, am I able to get my computer chipped or retuned? Its a rb25det 95'. Ive heard not, but stuffed if I can afford a power fc after replacing a blown motor.

Nice work on the 32 Warren, thats pretty impressivie power for the mods. My mate has my old 25 turbo in his 32, a bosch pump, cooler, pod, cat back exhaust, oil cooler, injectors, and it seems to be making a lot less than yours.

Well done Waz, glad that turbo is finally been put to good use, hey!!

Nice work.

Oi; I recommend going the SAFC & SITC route, so you get 2 ecu's, one to do the air/fuel ratio's and the other to do the ignition timing. Im sure you'd pick up a lazy 20-odd kw with those two added, and probably save a few dollars via better fuel economy as well.

Either way a nice result, as stated a decent ecu-mod (for the auto) would be the go (I use safc & sitc on my auto Rb25det), although I admit knowing less than nothing about this Dr.Drift you fella's are on about!

ross - I only know of TOSHI from these forums as having chipped an R33 GTST.

costs more than the r32 though as they can't be remapped on to the chip where as the same chip can be over writen on the R32 or something.

send him a PM and see what he has to say.

however, If I had an R33 gtst, for $950 or so, I would just save till I got that power FC.

if it was the same on the R32's then I'd do pfc for that too.

but it's closer to $1400 for R32's...

JAYCAR DFA is Cheaper than safc yes - Better? I doubt it is actually any better.

I'm sure SK posted that it doesn't actually do anything more or less than an SAFC.

and since SAFC second hand is under $300, I wouldn't bother trying to put the JAYCAR kit together myself...

gtst, I didnt realize a pfc could be had for my car that cheap.

Once I had one of those I wouldnt need a safc any other controller if I got the optional boost controller would I?

I was thinking of biting the bullet and getting some of those bosch coils and mounting them on firewall near igniter and running leads. What's your thought s on that? Do you think they are just as good as splitfires? I know that they are a hell of a lot cheaper!($300 plus install).

Cheers

Waz,

In regards to the cam gears,

I have a 33 with a rb25det with a front mount, pod, cat back 3inch. I will run a it more boost through it soon maybye 12-13 pound. Is there any benifit for cam gears for me with my setup? Ive thought about them before as its a mod that doesnt break the bank

cheers

Don't do the external coils. You will only save yourself a couple of hundred dollars for something that is a bit of a punt. Splitfires can be had for well under $600 lately if you buy from perfect run. The aussie dollar is above 85 yen atm so you will save a mint.

yes.. PFC replaces factory computer and is completely programable so no need for SAFC or ITC.. just a boost contoller to go with it. which one you use is up to you and your budget.

coils? do you have problems with your current coils?

it seems you are on a budget so I would FIRST try to tape them up with electrical tape. if it still fails, I would then replace them with Splitfire ones.

but I am a tightarse so it might be different for you.

exhaust cam gear on my car picked up more than 10kw broadly across the range. seems like a no-brainer when you do your timing belt.

thanks gtst and wolverine,

gtst, Im not sure if it was a problem with the coils or not but I aroldited and taped them allready and that didnt fix the problem. I am certain there is no vacum leaks or exhaust leaks as i had that thoroughly checked.

I am going to do the acc valve clean and adjust the timing on weekend and check airflow meter. Timing is to high (idle 9000rpm). It just boosts up fine to 5000 and then feels like it is hitting a boost cut or something and car just wont gain powere above that rpm. It will if I accelarate gradually.

The car is pretty standard bar a cooler, pod, and exhaust.

Any ideas of what to check on wknd apart from what I said would be appreciated.

If I remember rightly the auto is 15 kph per 1,000 rpm at the engine. So it has achieved a 40% power increase (50 rwkw to 70 rkw) at ~3,500 rpm. That's substantial gain in anyone's language.

Too late/tired to do an average power comparison, but I bet that is just as impressive.

:) Cheers :)

If the boost has increased above standard, then it is ECU rich and retard mapping based on the increased airflow as sensed by the AFM.

:) cheers :)

  • 2 weeks later...

shiny purple :) - see attachments

will be replacing the timing cover soon, but its off for the photos...

ross80 - i have no experience with the rb25, but based on my results i can definately recommend cam gears on the R33 - i believe you can only do the exhaust gear, however due to the VCT on the inlet side

cheers,

Warren

    • Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!
    • To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules
    • So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket
    • As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year. 
    • I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
