Nice work, I intend on making on of these, my question is ; What else from around the house can I use to heat the perspex

$15 heat gun from bunnings, otherwise blowtorch & wrap the perspex in tinfoil to stop it burning

toddlls idea isnt bad, but I found it was much easier seeing where the perspex was that I was melting.

BTW, I tried a normal hair drier and it didnt work :)

honestly, at bunnings I bought a cheapy heatgun for $12-15 bucks and it worked a charm. within 30 seconds it was almost like honey.

Gl with it.

your welcome guys,

also turael, i'll try to get some pics up over the next few days, cant believe its been in there for almost 2 years! But i can tell u now, run over it with a wet cloth and dry... still looks like the day i made it.... and I will prove very soon.... Not to mention i have taken it out to work on things and rested tools on it heaps of times!

Not a bad idea, the Perspex looks good. I made my own also, although I went a different way. Is yours actually fastened to the body? or just sort of slots into place?.

either way looks good, Top job.

I must say after 2 years it still looks great!

I was thinking of making a hole in the top and make a fibreglass tube from the snorkel into the top.

Will post pics when I'm done!

OK first up i gotta say that the heatshield looks awesome.

BUT... I have to ask...

You used perspex to make it from (I guess it's good coz you can still see the pod somewhat), and you used a "heat gun" to shape the "heatshield"....in other words since perspex changes shape with heat, how hot does the engine bay have to get before it melts??

very hot dude, like yeh if u placed the pespex on the exhaust manifold it would melt... but if you look it up on wiki:

http://en.wikipedia.org/wiki/Poly(methyl_methacrylate) its melting point is 130-140 degs celcius

and the heat gun was direct heat, whereas you'll find the heatsheilds normally just suffer from indirect heat like heatsoak from a hot motor...

Im keen on doing something like this for summer, oh and wicked job btw.

Does anyone know of a more heat resistant material to use? maybe some aluminium sheet metal with heat sinks around lol.. a little over the top?

Also have you had any problems with police? or is it perfectly legal?

thanks.

If anyone has some air temperature sensing equipment I could borrow to give some results, or if someone can point me in the direction of where to buy one within the $200ish mark i'll get some results.

I bought a fairly cheap 'automotive' multimeter from dick smith ot radio parts a while back which also came with a K type thermocouple or what ever they are called. You can plug it in and run the wire to the air box etc. Unfortunately you don't get two sensors two compare at one time but you do get a multimeter out of it too. Maybe one of your mates wants one too and then you'd have two readings?

    • There's no way they left the factory like that. In R chassis there is nothing stopping the steering wheel being put on one spline out from straight, and then adjusting the steering arms to "correct" it (sort of). As well as the indicator cancelling there would also be an issue with how tight you can turn in one direction to the other. The other (less likely) possibility is that the "clock spring" (the circular electronic part that allows the wheel to turn while still having an electrical connection for horn and any other buttons like cruise) might not be in place correctly. I don't have any pics of the R33 (or Stagea) setup but there would be a circular locating tab which sits in the steering column to have it straight...if that is not seated properly then the indicators may not cancel at the right point (and, you might also get a HICAS error since it would think you are driving in circles)
    • It will mostly be bad scoring on the bores, which you can almost certainly fix by machining for oversize pistons. I have to say, I am super surprised that any standard turbos made it 35 years down the track before exploding!
    • Thanks for the info mate was thinking 255/35 rears and 235/40 fronts
    • What's the difference? I would have said that between the front and rear axle lines, there's no noticeable diff between a GTR and an NA 2-door.
    • It will be salvageable. It really doesn't matter what is damaged. Opening up a 30+ year old motor for a rebuild immediately means a complete rebuild of the head anyway. Damaged valves just means an opportunity to put in some nice new ones. And in the modern day, why would you not throw at least a nice set of pistons at something. And if you're doing that, why not rods, and ARP fasteners, and so on.
