Can anyone reccomend somewhere in Sydney to modify an ally bonnet? Basically cut a vent in and smooth it out etc so that the lines flow nicely... I'd imagine the ally would need to be cut and then some massaging done...

Any suggestions welcome.

Nepean Valley Smash Repairs fitted the NACA Duct to my aluminium bonnet > resprayed.

They used a resin between the duct and the aluminium so that no expansion/contraction cracks would eventuate.

Long way from Berowra though.

Hi guys just FYI I am going to have the mods done at TNT in Girraween. They have quoted about $600 (allowing a little more) to cut vents, reinforce with tig weld (rather than glass over like alot of DIY jobs I've seen on the 'net).

At the moment I have a Border style bonnet in carbon fibre as pictured below.

It's nice but like most aftermarket body parts doesn't fit 100% like stock -in this case the bonnet does not reach all the way to the top of the fender so there is like a 1mm gap either side. Splitting hairs I know but when you spend top $$ on something you want it to be "right" (as I'm sure some of you know!). The Z32 ally bonnet is about the same weight as c/f (due to fibreglass frame being used on the c/f hood), but I like the vents in the border hood. Solution? User Border style c/f hood as a template and cut up a stock bonnet...

I'll let you know how it goes

For anyone interested in this little project my first attempt didn't go so well.

One of these was supplied as a template from which to modify the standard bonnet.

Shop says sure we can do that. Won't be able to get such an agressive ridge but we can do the vents no probs. I'm thinking this sounds pretty good, exactly what I'm after.

This is what was waiting for me when I arrived to collect it.

Can ANYONE see the similarity? Neither can I. Didn't bother arguing with the guys, paid them and left, and prompely on sold attempt number 1. Not very impressed though; the shop responsible for the work above came reccomended from a mate in the industry and gave every impression of being able to do the job. I suppose I could have argued the point and asked them to redo it etc but with the damage done sometimes it's easier to bite your tongue, move on, and not send the car there for a respray as you had planned to later in the year... anyway....

I've since spoken to a couple of classic/restoration style body shops and found one who's happy to take on the job (Gladesville Auto Body Works http://www.gladesvil...dyworks.com.au/). Owner Nat seems to have a fair bit of experience in panel fabrication and seems very much interested in making sure I get what I want. Will keep you all posted.

So here's how things are moving along

I managed to score another OEM bonnet in exchange for some spanner work, and dropped that off with Nat at Gladesville Auto Bodyworks.

Here's how it sat back in Feb. Just the centre vent and louvre done. Nat cut the vent in and made up an alloy frame to support the opening. At this stage it's riveted together but will be TIG welded once we know it all fits etc. Rear vents are yet to be done but you can see it's starting to take shape.

Fast forward to today and the rears have been done and it's ready for a test fit. I'm very happy with the work so far but unfortunately as you can see the bonnet doesn't quite close. The centre louvre is fouling on the front of the motor, so will need to be reshaped. At this stage the plan is to keep the opening/vent the same depth, but lift the louvre in and have it dovetail into the vent with a little more of a curve rather than in a straight line as it does now.

So yeah slow going at the moment but I'm happy with the progress. Once we get a suitable fit everything can get welded up and "finished" ready for paint.

Little bit more progress, again this is really just for anyone who is interested

Taking aaaaaaaages but as I think I've mentioned it's a fairly small job for the shop and I told them not rush, so I'm not disappointed with the timeframe.

Anyways here we have the vent modified to fit and the bonnet under primer. The louvered section is curved more than it was in the pics above so as to clear the front of the motor.

Nat (owner of the panel shop) measuring from the cross member to the bonnet. It wasn't quite sitting flush behind driver side headlight, wasn't fouling on anything so trying to work out where the problem is.

Everything checked out so some gentle massaging in order. No idea why, I suppose these things happen when you're dealing with second hand bonnnet going on a 20yr old car... The sheet alloy is very thin too so may have warped slightly when the frame for the duct was being welded in.

Ok and one last shot with everything lined up nicely.

Still far from finished, still gotta chop & fill a fair bit, then get some mesh in behind the ducts. Hoping to get it to the stage where the bottom is painted and the mesh is in, high fill, install (and adjust anything needed), then block it back a final time with it on the car. I've got different front and rear bars to go on too so will aim to get the lot painted at once and blended through the guards and doors nicely.

Long project but paying off and hands down the nicest bonnet I've seen on a Z32 to date.

Nice looking bonnet, glad you found someone competent. How much will it end up costing for the vents and respray if you don't mind me asking? I am keen to get some vents for mine cut into the bonnet, completely different to yours, but don't want the dramas you had first time round.

Fordy short answer is a lot...

This was done completely from scratch so there's a lot of time measuring/checking/fitting/checking/measuring.... You get the idea. It would have been much cheaper to buy a glass bonnet, or two or three glass bonnets haha.

I'd rather not put a figure on it, and the cost is always going to vary car to car anyway. If you're interested in doing something similar give Nay at Gladesville Auto Body a call and organise to bring the car in. I'm sure he'll do his best to give you an honest estimate.

Fair enough. Thanks for the contact details. I don't think my idea for my bonnet would be quite as time consuming as yours. Definitely something I want to do for something a little unique. There isnt much of an after market range for 31's.

Cheers

      After market rear camber arm adjustment

      By GTSBoy · Posted

      Wheel alignment immediately. Not "when I get around to it". And further to what Duncan said - you cannot just put camber arms on and shorten them. You will introduce bump steer far in excess of what the car had with stock arms. You need adjustable tension arms and they need to be shortened also. The simplest approach is to shorten them the same % as the stock ones. This will not be correct or optimal, but it will be better than any other guess. The correct way to set the lengths of both arms is to use a properly built/set up bump steer gauge and trial and error the adjustments until you hit the camber you need and want and have minimum bump steer in the range of motion that the wheel is expected to travel. And what Duncan said about toe is also very true. And you cannot change the camber arm without also affecting toe. So when you have adjustable arms on the back of a Skyline, the car either needs to go to a talented wheel aligner (not your local tyre shop dropout), or you need to be able to do this stuff yourself at home. Guess which approach I have taken? I have built my own gear for camber, toe and bump steer measurement and I do all this on the flattest bit of concrete I have, with some shims under the tyres on one side to level the car.

      R33 Fuel Pump & Brakes after alarm swap

      By Jarsky · Posted

      Thought I would get some advice from others on this situation.    Relevant info: R33 GTS25t Link G4x ECU Walbro 255LPH w/ OEM FP Relay (No relay mod) Scenario: I accidentally messed up my old AVS S5 (rev.1) at the start of the year and the cars been immobilised. Also the siren BBU has completely failed; so I decided to upgrade it.  I got a newer AVS S5 (rev.2?) installed on Friday. The guy removed the old one and its immobilisers. Tried to start it; the car cranks but doesnt start.  The new one was installed and all the alarm functions seem to be working as they should; still wouldn't start Went to bed; got up on Friday morning and decided to have a look into the no start problem. Found the car completely dead.  Charged the battery; plugged it back in and found the brake lights were stuck on.  Unplugging the brake pedal switch the lights turn off. Plug it back in and theyre stuck on again. I tested the switch (continuity test and resistance); all looks good (0-1kohm).  On talking to AVS; found its because of the rubber stopper on the brake pedal; sure enough the middle of it is missing so have ordered a new one. One of those wear items; which was confusing what was going on However when I try unplugging the STOP Light fuses (under the dash and under the hood) the brake light still stays on. Should those fuses not cut the brake light circuit?  I then checked the ECU; FP Speed Error.  Testing the pump again; I can hear the relay clicking every time I switch it to ON. I unplugged the pump and put the multimeter across the plug. No continuity; im seeing 0.6V (ECU signal?) and when it switches the relay I think its like 20mA or 200mA). Not seeing 12.4V / 7-9A. As far as I know; the Fuel Pump was wired through one of the immobiliser relays on the old alarm.  He pulled some thick gauged harness out with the old alarm wiring; which looks to me like it was to bridge connections into the immobilisers? Before it got immobilised it was running just fine.  Im at a loss to why the FP is getting no voltage; I thought maybe the FP was faulty (even though I havent even done 50km on the new pump) but no voltage at the harness plug.  Questions: Could it be he didnt reconnect the fuel pump when testing it after the old alarm removal (before installing the new alarm)?  Is this a case of bridging to the brake lights instead of the fuel pump circuit? It's a bit beyond me as I dont do a lot with electrical; so have tried my best to diagnose what I think seems to make sense.  Seeking advice if theres for sure an issue with the alarm install to get him back here; or if I do infact, need an auto electrician to diagnose it.

      Then, shorten them by 1cm, drop the car back down and have a visual look (or even better, use a spirit level across the wheel to see if you have less camber than before. You still want something like 1.5 for road use. Alternatively, if you have adjustable rear ride height (I assume you do if you have extreme camber wear), raise the suspension back to standard height until you can get it all aligned properly. Finally, keep in mind that wear on the inside of the tyre can be for incorrect toe, not just camber

      I know I have to get a wheel alignment but until then I just need to bring the rear tyres in a bit they're wearing to the belt on the inside and brand new on the outside edge. I did shorten the arms a bit but got it wrong now after a few klms the Slip and VDC lights come on. I'd just like to get it to a point where I can drive for another week or two before getting an alignment. I've had to pay a lot of other stuff recently so doing it myself is my only option

      You just need a wheel alignment after, so just set them to the same as current and drive to the shop. As there are 2 upper links it may also be worth adding adjustable upper front links at the same time; these reduce bump steer when you move the camber (note that setting those correctly takes a lot longer as you have to recheck the camber at each length of the toe arm, through a range of movement, so you could just ignore that unless the handling becomes unpredictable)
