Hi guys just wondering how people are modifying their bonnet hinges on a s13 so the bonnet sits upright by itself?
Any advice would be greatly appreciated, I would post a photo but Im not sure how.

Just lift the bonnet and you will notice tab on the hinge that hits and stops it from going any further. cut this tab off. and you will be able to put the bonnet all the way back to the window.

Do it it comes in so handy if you spend alot of time chilling in your engine bay, saves you having to the bonnet on and off constantly, I will be doing mine before the motor goes back in

As xris says but file tab back. U still want friction and tension on it when vertical makes it less resistant to be blown back over

Vertical bonnet has finally made it big in aus. Just be careful working with bonnet all the way up as they have a prepensity to blow shut as Simon mentions

Yeh don't leave tools on the side of the engine bay. My bonnet blew shut and bent the hinges, cos I left stuff there.

Ive heard tales of the bonet (standard, not carbon or fibre glass) cracking the windscreen from being tilted that far back?

Thanks heaps for all the info guys, I was wondering about the possibility of it blowing shut
also wondering if people get rid of their bonnet holding up stick thing and if so do they get rid of the bracket it attaches to?
This is on a track only car

being that far vertical = wind catch soooooooo easy

I'd put a lock or a secondary bonnet restraint so even with a quick gust of wind it cant go back further and smash the windscreen.

bonnet came open whilst doing 100kmh on my silvia didnt smash windscreen, it takes alot of force to smash the winscreen. Does anyone have some kind of way of stopping bonnet from blowing shut or back into windscreen?

I know of 2 windscreens that are cracked now after doing this mod.. it does increase chance of it cracking, windscreens are not meant to have shit resting against them.

Are you going to use the engine bay constantly?
If not there's no point, I'd only do it if I'm pulling/dropping engines/boxes in and out constantly. Apart from getting a crane in there easy there's no need.
Unless you want it for autosalon.
