Hi guys,

As I wrote in my previous post, my mechanic told me that my cam actuator in my car is stuff, and to fix it, I can either replace the part with a standard part or I can get adjustable cams and it will fix the problem as well.

Anyway, I am not very knowledgable regarding cams, I go not idea about size, angle etc etc.

Basically, this is what my mechanic proposed: "The price for the 260 pon cam's $1200.00 and the gears are $600.00 for the pair"

I was reading in another thread that the size and or what ever it is may be too agreesize for my car and I wont get much power increase.

I currently push out 273 rwkw with a GT2835 Pro s turbo. I wanted to hit the 280 rwkw mark with these cams but I am not sure if what I am getting is what I should be.

Also, does the price sound right for those cams?

What brand are pon cams, are they tomei?

Any help would be greatly appreciated as these are getting installed in my car on Tuesday so I need to know if they are the correct application for my car or if there is something else you guys suggest>???

Thanks guys!

Adj cam gears to purchase are like $150. $650 is a very... interesting price... even including labour.

As for 273 vs 280rwkw, who cares? You wont notice 7rwkw on the street and aiming for a 'number' is just that... its a number.

You could play with a dyno setting and get 7rwkw if you really want the number to pin to your wall.

Getting hung on numbers is a silly game to get into

IMO the cams, cam gears etc is a waste of money for what you want.

Bigger turbo/manifold/forged bottom end all come first as a stock R33 head is fine under 300rwkw.

But everyone has thier own view as you'll see with the replies that come out.

Hey mate, I just bought a set of tomei poncams for my car. There 256's and I payed about $800 for them on ebay. You can get them even cheaper from nengun.com if you don't mind waiting for ages. I'm still waiting to get my car back from having it's topend rebuilt so im not sure what the power increase is going to be like. My mechanic told me not to bother with adjustable cam gears atm.either. The cams are meant to be real good though they shouldn't stop you getting the power your after.

i was always told that 256 duration cams were the LARGEST u could go, without headwork being done.

is your head still stock?

Yeah my head is still stock.

I didn't want to get cams, but I may as well since it will fix my problem of the 'cam actuator' being faulty.....

Mechanic said that the adjustable cams would fix my problem (i only have 220 rwkw now as opposed to 273, and the mechanic believes its my cams actuator)

      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.
