Ok so here it is guys and gals,

I have a near factory condition 1994 R33 series 1 2dr GTS Skyline. Now it is different from all my past cars, but i am thinking not quite different enough . . . . . I wanna chop the top and get some air in my hair before it all falls out in my midlife crisis.

i am trying to figure out some way to cut it back and find someone to make either a carbon fiber or fiberglass detachable roof. Now i know that alot of the structural integrity of the car is held in the roof so there will need to be some major engineering to be done to the rest of the chassis.

So what i need to know if anyone can tell me is, what is needed to be done in the way of engineering? and is there anywhere good in southern QLD to go for this preferably in the toowoomba area?

Any advice is great guys

Thanks in advance :)

You'll never be able to get it engineered and road legal and I think you are underestimating how much something like that would cost to do properly.

I am aware that the cost will be more than substantial, heck i have 20k put aside for this project so far. I am not worried about the hanndling as i only use it as a cruiser not a high performance beast anway

I didnt ask to be told that it cant be done, because in my eyes nothing is impossible, i asked because this is one of the few site i have found where some people know what they are talking about and might have some useful advice.

Didn't say it couldn't physically be done. I said to get it approved/engineered in QLD to make it road legal would be next to impossible.

The handling is the least of your worries. The roof/windscreen make up the main structural rigidity of the vehicle. There is a reason why convertibles weigh 30-60kg more than the equivelent coupe/sedan as they have to make up for the structural loss. Hell drive a factory aero-top Supra with the roof off and feel the whole car twist and vibrate; and that's a car that was engineered properly by the manufacturer.

You wanted advice, we are giving it to you. If you want people to blow some smoke up your ass by saying "Yeah man do it, piece of piss, just chop the roof" then go on Boostcruising.

As said above. You want a nice Nissan convertible cruiser buy a Varietta and drop a turbo motor into it. Will also look a hell of a lot better.

For starters; Double your budget. At least.

How much are you planning to do yourself?

A custom made Carbon fibre roof and attendant mounting structure? I'd say that would be all of your original budget right there.

You are right; nothing is impossible. The question is; can you afford it?

I would suggest you go and talk to a race engineer or a rod shop that does a lot of custom steel fabrication. If you are serious (and they'll be able to tell :whistling: ) they'll be able to outline the issues that will cause problems, and also the costs.

Go from there.

And when you start; do a build thread for everyone to follow.:thumbsup:

    • Hey guys,  Way back when (about 15yrs plus), I picked up a beautiful set of Tein 'Super Racing Spec Circuit Master RE' coilovers from Russman. I have legit never fitted them to my car, as it was garaged indefinitely while i bought a house Yada Yada. They look brand new! Anyway its time to pick up where I left off, and have started doing some khanacross and am booked in for a hill climb next month. The car has some hard af Nismo shocks in ATM, which has me wanting to upgrade again, and now I am left wondering if it's worth having these teins rebuilt? I think they where an ok shock back then, but how do they compare to what's on the market now?  Shockworks/mca are 2800+, and I am sure they are great. But if I can have these rebuilt and be better than, say, a set of bc's for around the cost of bc's, I would be happy with the performance v cost trade off.  If they are considered outdated and rubbish these days, so be it, I'll put them on the shelf and be happy to look at the pretty green colour while I save for the SW/MCA option. Grateful for your thoughts on the matter, and suggestions on who could do the rebuild if it's a worthwhile pursuit.  cheers, Rowdy. 
    • I can't speak for the US, but for Canada as I mentioned above, all fuel gases contain ethanol. We have regulations for E5/E10/E15. Each province handles it differently but basically any fuel gases sold must be E10 and slowly increasing to E15 by a certain year. 
    • Hey guys, Purchased and drove up new wheels from Vic last weekend. Car never been registered in Aus before. Only thing was aware of was pod filter which reverted back to stock. Went to get blue slip in western sydney. Everything with car fine (compliance etc) and knocked back for coilovers. Was told illegal and need engineering cert. Called the certifier they recommended and was told at min $1000 to certify them. I was then told HP can STILL defect you even with them certified. All this was news to me. Is this just a case of deal with pay the $1000 and run the risk? Kind of nuts given the amount of people running with coils I know of. No one I know has OEMs to use to pass, either.
    • Welcome mate. Best Stagea is best Stagea. How is it driving a correct hand drive vehicle driving on the right? The Japanese do the opposite here and they've made parking boom gate ticket things on both sides to cater for LHD and RHD cars, as there's so many of them (mostly German but there are quite a few American cars too).
    • So of these and these, which ones have ethanol in them?
