R33 Gtr Rb30 Fitting Vented Bonnet?

[leeroy_25]

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

Generally they wont fit

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.

Well mine is not a Top Secret or Jun bonnet, but it has all the cooling vents, in the right places and easily clears my rb25/30, with a high mounted single.

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...

I'm running a 25/30, has the 26 cam covers, It fitted with not too much drama. I'm not running the timing cover though.

One topic is more than enough - threads merged.

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

a friend of mine had a 2630 in his gtr with a high mounted to4z and he has a vented bonted on his but he has cut another vent in it to clear the front of the engine.
