How To: R33 Secondary Bonnet Restraint


Recommended Posts

Hey Guys,

I thought this would be relevant to a few people around these traps.

So, you've got a R33 with a stock bonnet, you're doing track days so you need a secondary bonnet restraint.

This is how you do it

Step 1. Buy this junk.


1x Meter of 3mm galvanised chain. = $3.77

1x Snap Hook 60x6mm = $4.18

2x D shackle 5mm = $1.47

I got mine from Roberts Hobart on Collins Street.

I cut my chains so one was 48cm long, and the other was 17cm long.

Loop the long one through the top holes, I used a piece of wire to help pull it through.


Loop the short one around the bracket that holds the stock latch in position. I could poke mine through the radiator shroud because it was already damaged, you might need to be a little more crafty.


Then clip the Snap Hook onto one of the ends and it's all done. :D

I hope this helps a few people.

Made a couple of these a while ago, just be aware that the weakest part of the thing is the snap hook on the end which are not rated that high, so you can go smaller chain, I found all this info on the Bullivants web site

Still got some left from selling them at events for $10.00, if your in Sydney and could be bothered Ill give you one for free.

The D shacles bolts onto a existing hole on the stock bonnet lock mechanism and the spring clip hooks onto the male section on the top of the bonnet, when open it allows about 80mm gap to get a fire extinguisher in.

    • Haha, I’ll just have to do both… I’ll be upgrading the Skoda Kodiaq work car eventually..
    • I'm not sure if this helps or not. I recently upgraded to R34 Vspec2 Brembo's on the S2 Stag. I used this braided kit: https://safebrake.biz/home/292-skyline-gt-r-r34-awd-26tt-brake-upgrade-safebrake-performance-hoses.html Beyond this I got the R33gtr front brake hard lines, that go over axle hub just behind the dust plate and all lined up beautifully.  The braided lines were same length as the stock ones. Needed to buy 2x longer bolts for one of the hard mount points for the braided hoses up the front. Trim rear dust shields so could fit 322mm discs. It's a pretty straight forward job.   ps. the r33gtr hard brake lines have the flare nut so should bolt straight into your callipers.
    • Hi All, Just wondering if anyone has changed their stock front upper /  inner control arm bushes for nolathane and has any advice on doing so? See pic circled in red with the bushes im referring to. Can I do it myself? ie. with an air chisel and a suitable sized/diameter socket on the end. Or is it a hydraulic press job? I've already done the outside bushes, the originals popped of easy with the air chisel as they had a little lip to get some purchase on. Cheers, Pete    
    • Mate, great looking R33!  It's not too late to go European and spend your days talking about how you went from v1.01 to v1.03 of your Stage 1.5 tune and now you can bake off the line holding your chai latte without spillage. 🥲 I feel you're at the point of no return now, brace yourself!  
    • I have a Toyota Estima hybrid AHR20 2013. The diffrential arm bushing need replacing. The OEM differential arm part number is 52380-28050. Please let me know if you know anyone who can supply or supply and install the differential arm bushing. I have asked Febest Auto Parts, Auto-Parts and Auto Plus Parts, without any luck. Thank you in advance for any relevant information.
