Ok guys finally for motivated and welded the holes in the boot of the 32 and now I need to do my gtr are Bonnet

These are my options and I'll explain why

Option one is to tig the holes up before anyone says anything yes I'm a qualified sheety and I know how to weld ally

The only thing is I've never welded any that thin it looks to be about .7mm thick and for any one that knows ally knows that at the rate that ally heats up it won't take much to warp the shit outta my bonnet

Now my idea is to put a backing plate behind the holes and to get a nicer finish on the inside

I also am thinking of getting some preety solid Dolly's an brass blocks to put around the weld area to soak some of the heat due to the tig welding and te amount of heat i will putting in there hopefully aiding in preventing distortion .

Any one welded one before or the Same thickness or thinner material ?

Other option is to sikaflex a plate on the isinde and fill them with filler but Is a lil dodgey

Any help appreciated

Cheers

Bejay

Tried to repair a few GTR bonnets and I can tell you don't even bother trying.

The material they used is rubbish to weld,

If you've ever tried to weld a recycled alloy street sign a GTR bonnet is verging on the same material.

      R32 GTR clutch master cylinder adapters

      I replaced the whole clutch line with the chase bays braided hose, I think it removes that loop, is it the short hose that comes immediately off the slave or is there a drawing in the manual to find what you’re referring to? It was just re-bled when I upgraded to the nismo slave, old slave worked fine but I thought that might help, didn’t change a thing. It’s like the first half of the pedal is pushing air and then when it finally actuates the master the friction zone is tiny. Makes it practically impossible to launch the car

      Yep, that was one of the things we learned fast in the past with our MX5. When you drive with the top down, you are effectively standing out in the sun, 100% of the time, and not getting in any shade (because roads aren't shaded generally!). Just like standing out in the middle of a field on a sunny 27C day is a bit of a bad plan, so is sitting in a MX5 without sun protection.

      I also just ordered some Frankenstein bolts and side mounts to fit a hard top Just in case I do find one, basically so it doesn't need to be fixed to the car with only the front latch.......and then gaffa tape to keep it in place for the RTN journey from wherever I get it

      If your temps are fine now, you probably won't have any issues with where your vents are as they don't look right up at the windscreens high pressure area, so any differences when giving it the beans for extended happy laps would be minimal, but, they should vent heaps when stuck in traffic  Much like how that reverse cowl on my SS let "visible" heat out when stationary, but, because it was basically at the windscreen my coolant temps on the Hwy actually raised because air was being fed into it at speed (110kph), to only come back down to around 90° when I got off the Hwy And your 100% correct about the NC currently not needing vents, but, if I was to add a turbo, and a oil cooler and intercooler in front of the condenserand radiator, and then take it to the track???? It is apparently a recommend requirement if I don't want to worry about coolant or oil temp issues, but, any of the above are possible scenarios, over time As it sits now, with the triple pass radiator and stock air conditioning system, I have absolutely no issues with either temps or air conditioning efficiency, I've been basically daily driving thie car for the last month, both on the Hwy, and peak hour, bumper to bumper traffic, but, that's pretty much expected from basically a standard engine  Talking about no issues daily driving, it was 39° the other day and I was sitting in bumper to bumper traffic on the M5 and then M7, with the top down, and with the air conditioning blowing nice cold air on my feet, balls, and face, well, there was one issue, my head and arms got pretty sun burnt Note to self: leave a hat and sunscreen in the car for such days 🤣

      I would agree, unless you need something specific to the HV motor/battery side repaired or investigated, any mechanic will be able to perform normal services, but if you prefer, maybe look for a mechanic who regularly services/repairs Nissans, the VQ engines are pretty common in the Nissan lineup.  Sorry, I can't make any suggestions, I don't live in Vic.
