depends how rough you intend to be on it mike, no diff in the world will stand up to being mistreated, conversely, most diffs will handle more power than you think if you treat them right.

What do you mean by track? There is no class where this car would be competitive. If you mean the occasional sprint day, then a 1.8 diff will be plenty. Unless you're drag racing, you're wasting your money.

I have done that too....

last month after I got the car retuned we decided to dee how it came up on the transbrake.... on the street.

Launched at 6000rpm and the car wheelspun for about 200m, hitting the limiter at 10000rpm..... car was going crazing, hit the brakes and slid towards the gutter, LUCKILY when I did hit the gutter, it was a driveway :) just missed the drain.

now check what time i bought the car........hmmmmm, that would be about the 8th of february wasnt it? strange, this was posted up at the end of february wasnt it? wow, that must be a coincedence that i was doing burnouts in adelaide when my car was supposed to be on a transport truck coming here???? strange indeed.......

whats also strange is the fact that the plates in the movie are different from the plates on my car? hmmmm, there's a lot that doesnt add up right now isnt there? i dont think i need to use any emoticons to show that i am really pissed off right now!

Dude calm down... Breath in, breath out...

I don't know if this is your car or not, but I can assure you that first video was taken well before you bought the car...

I remeber seeing it last year - IIRC it was actually posted here some time ago, and I may be mistken but I think that car is the old 13bt one that got chopped up a while back... I could be wrong about it being the 13bt one, but the vid is certainly much older than feb this year....

Mate I am not assuming it was up before feb, I can garauntee you that first video was taken at least last year, maybe earlier...

And it looks liek it had steel wheels on the back too...

Yep, that movie is really old Mike. I saw it at least a year ago too.

You know that a car like that is going to be built for people to drive hard. Some people just take driving hard a little too far...

PM or ring Duj and find out, there's no one better to explain it than him.

if it's the video i'm thinking of, it's not yours. it's another rotor MX-5, has a 13BT & featured in FastFours. when it was torn down Duj bought some of it's parts for his.

You are worried about loosing tyre tread??????

and you are surprised to see your car being spanked????

what did you think when you bought this car.....dríven by lady on weekends only?

I think you are wasting way too much energy on these vids. Keep your energy for getting it right.

Like boagsy said. It was a car built for doing crap like that. & that you are having issues is no real surprise.
It is a highly modded car & it takes guts & determination to get it right and see it through.....plus a sh*t load of money.


Please don't let this deter your project.

just get it out of your mind & focus on what you want with the car. Forget its history.....as such.


good luck.

Hmmm... Your wondering why the plates are different...
BECAUSE ITS NOT YOUR CAR!!
I ended up wrecking that car and selling most of the bits off Mike,
It was double defected and under finance so it was stripped and chopped up.The wheels are different for a start they're Work VS wheels.
The video is a few years old as well

Jeez why wouldnt you just ring me and question me about it...?

lil_kim wrote:yes, the previous diff was a 1.6 with a viscous centre. YES DUJON IT WAS VISCOUS NOT CLUTCH PACK!!!!! :evil:


Which makes no difference since neither would hold up to being dríven like a cock. Which Duj's (your) car wasn't.




Dude, that one in the video is a completely different car, that was owned by Jay who now has that blue Cressida with the 2JZ thats been all over the net and has gone to a few interstate drag and burnout meets and gave my cousin's Hayabusa a good run on Anzac Highway. There are numerous stories going around about the 13B MX5 he had (ie WDM-354) Managed to blow a bloody starter motor at the Mount Lofty carpark one freeeeeeeezing night after arriving and trying to impress people with a massive burnout, then everyone left. Drove it down Jetty Road with no bonnet while on defect.

It was a very well known car, both to people around Adelaide and the 5-0. But it wasn't your car, and was dríven about a million times harder than Duj drove his (your) car. Also, the bloke Duj bought yours from is about a million years old and would have been lucky to get it on boost let alone go and rip hektik burnouts like it sounds like you tried to do when you smashed the diff so well that your mechanic was scared to pull it apart.

You've met Duj, and you know how small the cabin of a MX5 is, especially with a hardtop on. Do you REALLY think he'd fit and have his head as low as Jay's is on that video you put up of "Duj" driving "your" car. Tread loss between you seeing the car and getting it off the truck as evidenced by the video of "your" car doing a massive burnout? Man it must be as fully hektik as your old worlds fastest rocket powered GTiR that actually handled fully good to have killed the tread on the wheels that were ON THE FRONT, on a different car, a couple of years ago.

I've bought stuff from Dujon and he's been awesome to deal with. In fact, I don't know a single person apart from you who has a bad thing to say about him, and since you can't even tell the difference between a chrome 18 and what looks to be a 14 inch stockie painted black, I'm not going to count your opinion.


Like I said months ago, and like others have also said to you, you're not going to be able to run it in a decent class so stop going on about being a hektik circuit driver and rally driver. Get a 1.8 diff and stick it in yourself, don't run big boost, don't drive like a dick and just enjoy it on the road and maybe do some hillclimbs and sprints. It will be fast, make the right noises and impress all the kiddies at Maccas. If you want to have some fun on the track and really test your skills behind the wheel, take the two grand you'll save on not grafting a RX7 rear end into the car, put it together with another couple of grand you'll save by actually getting your hands dirty doing the relatively simple stuff that you've been shelling out to have done by guys that you end up slamming on the internet afterwards, and buy a kart.

All the "I'm gonna do this and this and this" stuff that you go on about for the MX5 is going to cost you an absolute fortune, make the car worse to drive, pretty much make it useless for the street and make it even harder to sell when you decide its crap and you want a new Barina instead because you're so sick of the constant problems with the MX5. Drop a few grand on a kart and all the associated bits for racing it, and just go and have some FUN, and keep the MX5 pretty much as is where its still fun to drive and own. It might not sound as impressive to tell your friends that you have a kart instead of a fully sik widebody rotary MX5 with a RX7 rear end and all that, but hey, you'll still have a nice 12AT MX5 and I'd hazard a guess that none of your friends do.

The other point to consider is that if you continue to pour money into the car, not only are you never going to recover most of it if you sell it (which you definitely won't), you'll also lose out big time if something happens to the car. You could crash it (probably doing something stupid in which case insurance will tell you to take a long walk off a short pier), or someone could hit you (like that kid that put a kit on his car and painted it, then put the photos up on here and got hit by a truck the next day, pretty much not his fault at all but the car was stuffed), or it could get stolen (heaps of Skylines have been stolen in Adelaide this week, possibly to be rebirthed as repaired flood damaged Newcastle cars or for parts, and your car would have a few parts that would make it worth stealing). You won't get much back compared to what you'd have spent on the car, all that time you spent slaving away vacuuming rental Getz's to earn the money to pay someone $60 an hour to do stuff to the car and for parts, all for nothing. A bit of cred among your friends maybe, but once the car is gone, the cred disapeers aswell, and Young & Cool Insurance will give you a cheque for $7000. And you'll cry. Seriously.

In the end, it's your money and nothing I say will change that (except you might manage to keep a bunch of it if you listen to me), so if you want to spend it on your car, do it. Just don't go bitching about people (or workshops) on a public forum when you don't have your facts straight.

Oh and you might want to go and apply for a job with Nissan, your awesome mods that made your GTiR handle better than a MX5 would have been very valuable to them in '92 since the GTiR's awful weight distribution and renowned propensity for understeer forced Nissan to drop their WRC aspirations. They'd probably value your input on their upcoming models
