I'm running 272deg 9mm lift camtech cams with a GTX3076r. 300rwkw on 15psi. High quality parts, no complaints here what soever. No VCT here. Can't recall if the 268degs were out with VCT support when I bought mine or not.

bottom to mid is what will be affected by vct. interested to know...

Reflector: post up a dyno graph if you have one

This is without the cams degree'd (currently doing it now - Cars off the road).

Running 14-15psi through an Apexi-AVCR however we're ditching that as the boost controller in the future and using the Link G4 to control the boost. Going to put 18psi through mid range and bleed off to 15psi. Once I get some spare dollars I'll rebuild the bottom end and then the fun begins. In regards to driveability, it's a kitten down low, drives perfectly, put your foot down and it's a lot of fun - need some stickier tyres haha ;). This set up was built with 1/4 mile in mind as well. We had to put limitations (cuts) at redline (7500rpm) as it wanted to keep making power above and beyond but with a stock bottom end, there's not point pushing it.

Thats a nice linear power curve. Looks like mine. We hadto put limitations aswell on my car (7650) for some reason the power doesnt taper off. Never opened up my engine after buying it off a member here so im unsure if the heads had some sexying up or what. I can drive mine all day when cruising but when she's open everybody hears it

Thanks man. I copped a lot of negative responses when stating I wanted to ditch VCT. In all honesty, I'd be interested to see the difference with the same set up with VCT enabled (guess smaller inlet cam with VCT support) but these RB engines really perform beautifully from 3000rpm onwards. It all depends on what your goals are.

Question is, what are you hoping to achieve? More response, more low down torque, more top end power? What other supporting mods do you currently have?

Camtech are a good choice regardless, great customer service and their products are high quality.

Well currently im making 300kw. Tomei fuel pump greddy plenum 3076 .82 with a tial 44mm gate straight through 3 inch exhaust power fc. The usual stuff. Im putting hks 256/264 cams with a hks ex cam gear. Tomei springs. Nismo 740cc injectors. Nismo thermostat. Nismo reg. Iv recently just finished my 044 and surge tank setup. Just spoke to the guy who's tuning it. Im upping the boost to 20 to 22psi. Aiming for 330 plus kw. I use the car for drift and street driving. But I want to break into the 11s and run a 120mph pass. So basically my car will be an all rounder.

      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.

      R32 GTS (RB20DE) Injectors Replacement

      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.
