Get the cams changed, to the suited ones for a R33 CAS.

 

Time wasting and a pain in the A$$ but its the only other option if the FC doesnt work with the R34 cas.

 

Have you done a sensor check on your FC ?

Hi cameron, How do you do a sensor check on the Power FC? What we did do is connect up the R34 CAS to the loom and with the ignition on, spun the spindle and nothing. We did the same with my original CAS and the fuel pump started whirring. So we think maybe something might be wrong with the CAS and it is faulty cause it gets no signal.

Thanks cameron

I thought all the non-neo RB25 had half circle drive?

well they do from what I can see.. inside the actual "drive" (which is actually a star shape) is a half crescent that hooks up to the cam in the correct position, which I assume is the "key".. i think maybe that is where the confusion is?

For the time you will end up wasting on mucking around with, cams, cas, computers. to trying and get it to work. It would be quicker if you pulled out the cams, contact your supplier and get them to send you the correct cams ASAP and then you send back the R34 ones when they arrive.

For the sake of pulling off the timing belt and water pump, its really not that much hassle, compared to messing around with the wrong CAS, which could give you the wrong IGN reading, which could potentially damage your motor.

That is if your certian they are the wrong cams first.

The cams will work fine in the motor,

The R34 crank angle will work fine as well you just need to rewire it probably needs a pullup resistor inbetween your 2 signals . Grab a multimeter and test your voltage signals and rewire accordingly.. I will call you with regards to this anyway Bullant Im home tomorrow and can do it for you. no point in changing the cams took you long enough to get them from Japan.

Br,

Well if they are the wrong cams, hes going to have to unistall them and send them back and get the correct ones.

You can't run a car with the wrong cams.

The R32 and early R33 models run the 8-point star drive and the half moon that comes out from that locates the CAS in the right position. Like Predator said

Late R33s and R34 cams run what looks like a single strip of metal deep down inside the cam which I think is offset to prevent 180 degree mis-alignment.

Also R32s are hydraulic cams and R34s are mechanical.

I know early R33s are hydraulic cams but I would not be surprised if the late R33s are mechanical cams. Unsure.

But I'm guessing you're getting no zap zap at all out fo your motor

I have never seen an R33 GTST RB25DET (non Neo) with solid followers, they have all been hydraulic. The only solid follower equiped RB25DET's I have seen have been the R34 GTT Neo versions.:D

Well thanks all for the advise, the R34 NEO cam is on its way back to the land of the rising sun. The correct cam is on its way to the land downunder which will allow us to use the R33 CAS and hopefully will be be installed on Tuesday.

Thanks again for all the expert advise and we can all learn from this experience.

Good to see you worked it out,

The moral of the story, All ways check your cams before installing, cause its a b!tch when you have to pull it all out again and put the correct ones back in.

      Duncan's V37.......race car?

      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.
