not sure if this will q be beating a dead horse or not but here goes:

any of you experts consider using the 300zx (z32) rods ? please share your thoughts on this.

If my memory serves me correctly, they are way too long, and with the price and availability of the rb30 stuff, there would really be no need

gotcha!

i should do the math first. the 300zx rods is 1.8mm longer than the rb30 (6") rod.

even with the combination of the 300zx rods w/ the rb25det pistons it still protrude above the deck.

hmm...a thick headgasket may solve it. the availability of the 300zx here in he States are abundant and so cheap.

the GM SBC rods option is also dirt cheap: 250.00USD (266.010 AUD); make this also a nice option i'm itching to dive into.

hey im buildin my rb30det atm and im tryin to sort an intake setup 4 it. Using a rb25de head i was considering using a factory intake but have the plenum modified to front facing. But recently i heard that this mod can lean out the 6th piston or something. Any opinions or advice would be great.

Thanks for those pics fellas, ive been tossin up which way my piping will go.

Either way looks good with dan's having slightly more bends?

also what ex manifolds are you guys using (dan and sir racer)

cheers

If you are after a quality exhaust manifold i highly recommend 6boost or Extreme Turbo Manifolds (ETM). I am using an ETM item and my mate is using 6boost; both work of arts :teehee:

Did you cut a hole where the battery used to sit?

My previous skylines have been defected for cutting holes, DOT inspectors said it weakens the crush zone of the body and all piping should go through factory holes or be plumbed around the body.

My current rb20 piping is done this way.

I wish the service was the same quality. ;)

For some reason Leigh (ETM) quoted me higher through these forums, and $150 lower (same car, same manifold) on CLT forums under a VLT orientated username.

They both take months to reply to pm's and email, thats if they do...

The prices these days are a bit steep for a street car.... I'll be making my own. :bunny:

hi guys, not posted for a while.. right section now, :D after some advice as usual.. my rb26/30 has now done 2500 miles no problem whatsoever, but is under turbo,ed.

Nah R33 has battery in the boot from standard, But I had to remove the windscreen washer bottle that I will replace with a alloy surge/washer bottle when the wallet permits

There is a region below the washer bottle where the GTR piping is run through as standard and the rail is exactly the same in a 33 GTSt. It even has the shape stamped. Cutting the hole and finishing with a little reinforcing is generally fine. Do a good job, tell them it is factory and if they want proof get a mate with a GTR and show them or take photos.

Was wondering if many have used the rb30 gearboxes? I bought mine with the block im using for my 30 build and iv heard heaps about the gtr and 25t g/boxes bein really strong but not so much is said about the rb30 boxes. So any advice or opinions on their strength? also what are the ratios like? Cheers.

    • 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.
