Guy's dones anyone know if fitting a vented bonnet like the Top Secret or Jun style ones will be a problem with an RB30 conversion? Just had the thought as I know the bonnet it quite tight on the timing belt cover with the stock bonnet and these drop down in the middle where the main centre venting is? Help please! If some can reccommend a suitable bonnet to run with the RB30 if these are no good that would be great as I have some serious underbonnet temp issues wth the downpipe and top mount all in a very small enclosed space!

Cheers

Lee

I think you'll find some can fit, the 33 rb30 from my experience has more clearance cause of the shape of the stock bonnet in comparison to a 32 (which we all know has a terrible time fitting the engine in and bonnet closing).

Best bet will be to go to a shop with the bonnet you want, do a trial fit on site.

Hey mate,

I have a friend with an RB30 with a similar bonnet to Top Secret style (one vent at the front that dips down) and had to remove it due to it fouling out on the cam cover. An adequate solution would be to get the Nismo Z Tune style bonnet, it doesn't dip down near the front of the engine. Only problem is trying to find one. I bought mine about 5 years ago but the company that made them in QLD have discontinued them.

Hope that helps...

Thanks for the replies guy's Al, That is a possible solutoin I could either customise my stock one or maybe do a custom bonnet complete. Will see what comes up!

Sorry for the double post. Was not sure where this was best placed.

Thank you

Lee

    • I know this one’s the BB one. My tuner did make mention about the actuator. I am curious about the VCT as well
    • Might also needs a stronger actuator with the right preloading. With older 2019 built bush G3 units, BB upgrade or 21U housing down size makes a pretty decent gain in response as well. 
    • Hey lads  so im finally putting together my rb30 forged bottom end and ran into an issue. I measured my main bearing clearance with arp main studs torqued to 60 ft-lbs using ACL H series STD size bearings and standard, un-ground crank shaft journals and got an oil clearance reading of about 1.3 thou measuring straight up and down and about 2.8 thou measuring at a 45 degree angle (just above and below the parting line). My machine shop said they measured the main tunnel and it was all within spec (they didnt say the actual measurement) and to go with a standard size bearing, which i have done and the clearance is too tight, I'm guessing because of the extra clamping force from the arp studs distorting the main tunnel. I was wanting to run about 2.5 thou main bearing clearance.  My questions are: 1. could i just use the HX extra 1 thou clearance ACL bearings? that would fix my straight up and down clearance making it about 2.3 thou, but then would the side to side clearance be too big at around 3.8 thou? 2. what actually is the recommended main bearing clearance for measuring near the parting line / side to side. i know its supposed to be bigger as the bearing has some eccentricity built into it but how much more clearance should there be compared to the straight up and down measurement? at the moment there is about 1.5thou difference, is that acceptable or should it be less? 3. If i took the engine block + girdle back to the machine shop and got them to line bore the main tunnel (like i told them to do the first time, but they said it didnt need it) what bearing size would i buy? the STD size bearing shells already slide in fairly easily with no real resistance, some even falling out if i tip the girdle up-side-down. If im taking material out of the main tunnel would i need a bearing with extra material on the back side to make up for it? this is probably confusing af to read so if something doesn't make sense let me know and ill try explaining in a different way. My machine shop doesn't come back from christmas break until mid January, hence why i'm asking these questions here. TIA for any help or info 
    • I bought the model back in Japan in Feb. I realised I could never build it, looked around for people who could build it, turns out there's some very skilled people out there that will make copies of 1:1 cars or near enough. I'm not really a photo guy... but people were dragging me in a group chat for the choice of bumper as someone else saw the car before it was finished as they are also a customer of that shop. I took the photo in the above post because I was pretty confident that the lip would work wonders for it. Here's some more in-progress and almost-done pics. It gives a good enough idea as to what the rear looks like!   I have also booked in a track day at the end of January. Lets all hope that is nothing but pure fun and games. If it's not pure fun and games, well, I've already got half an engine spare in the cupboard 
    • Well, do ya, punk? Seriously though, let's fu<king go! The colour and kit looks amazing on the car. Do you have any shots from the rear? I don't quite follow how the model came around. You bought the white kit and he modified it to match your car? Looks nuts either way!
