you probably need to be more specific, but I suspect jetwreck can just go and check up on any questions by looking in the garage. bastard.

ahk, im basically just interested on what was done to it to get it to the level it was at, so really just everything.

I always had a feeling that the Group A cars were being underdriven a tad as the owners are not always gun professional drivers + their cars are expensive and often of significant historical value. But...

Wow, Seto jumps behind the wheel and blitzes them :P So glad to see one of the old Grp A cars turn a bit of genuine speed. I was starting to get concerned by the fact that my lil GTSt can do similar times

Give us a couple of thousand laps around there like Seto and we will get a bit closer. Some of us have only done about 15 laps. I also think that 5 seconds off Seto's pace in the wet is pretty good for non professions.....and bringing them home straight on top of that. Good weekend had by all.

Well done to David Towe(BMW) who won & Bill Cutler(BMW) for third in the last race in the wet.

I was not having a dig at all. The std of driving thru the field is better then i could ever do. Anyway, if i had any one of the cars out there i doubt i would be able to race it becuase of the cars value and the expense to source parts and repair. So massive wraps for both punting the cars in the first place and doing it as well as you all do.

But, there are street cars in the car club that are quicker and it has always left me wondering, has car development come that far in the past 20years? Are semi slicks that much better then the tyres that were run 20years ago. Or does the old power vs weight with good grip will bag you better time? So for me it was good to see the M3 show the turn of speed it did :/

Any truth to the talk late last year that Richo, Seton and Bowe could be regulars this season? Be great to see, and i imagine as a competitor awesome to be racing against drivers of that calibre

I just re-read my response.....sorry my response reads a little different to how I had it in my head.....I know what you were saying and it's pretty clear you weren't having a shot at us.

There are some pretty quick street cars out there I agree.....but can they do 1,000k's at 9/10's or even 40 laps at Eastern Creek at that. On top of that do they get better the longer they go? I have driven some pretty well prepaired street registered race cars in the past and non of them really do the race thing as well as the Group A's or a purpose build race car. Power to weight with good balance and grip should always pay off. I find if you have to much power it is very easy to overdrive the car, or make tyres go off. This is OK for short races or sprints but not for long races. Just to be clear I am talking about Circuit cars not Targa/Hillclimb/Sprint cars.

Richo is still racing his Falcon, Bowe his Mustang and Seton his Capri. What I can tell you is Seton may be driving MCM this year with us. Wether it's a BMW or Sierra I don't know. Unfortunately I wont be racing at MCM but Dad will.

P.S. Payback will be sweet if it rains at MCM....I'll see how Dad likes semi slicks it the rain!!!! :down:

thanks mate.

I just wanted something better than the pissy little one i found.

If i ever get to the stage where i have more money than sense, i would love to build a complete replica in that colour scheme.

Hehe - I have same vague plans for a track R31 in Group A guise. This PDF scan may help for a 32 replica.

From memory powerplay imports have the GIO R32 for sale... POA of course

      So, version 4 intake is on its way I was looking at these a while ago but at around $200 or more it was a little pricey for something that might not work, but, I had it in my watch list, but, I got a message saying it was on special, and I had a code thingie to use, it eventually came in at $120 delivered, so BAM, BUY NOW.....LOL I'll need to have a look when it arrives but I feel it will "look" better than what I currently have, as it comes with a PCV fitting, so I will be able to get rid of the alloy pipe that goes to the throttle body with the PCV fitting  Well, that's what the voices in my head are telling me  Oh, and this happened today Yeap, it was a Trojan, and it was cheap, so I headed back to the hardware store and actually spent a little bit more on a heavy duty,  one that was actually recommended by a plumber mate, a Cyclone one with a fibreglass handle that is actually rated for clay The broken shovel will eventually be "modified" into a short handle shovel

      What should I do next to hold the head on

      By MBS206 · Posted

      When you pulled it off, there is no signs of blown head gasket? Is it possible you have some other issues going on? Possible cracked blocked? Or do you think it's straight up lifting the head? Did you check what the head was torqued to before pulling it down (To see if possibly they're stretching, or starting to break threads out etc)?

      Chris' Toyota Mark ii JZX110

      By Rezz · Posted

      Seems like a decent result for a modded JZX110. They are bulky in comparison to the 100 and 90 models (which I'd prefer myself) but they are getting very few and far between here in JP these days. Thanks for the detailed review and the import process into the UK. I also have a car which I'm hoping to export from Japan at some stage so it's good to know if someone from the UK was interested in it. By the way the corrosion underneath is par for the course for cars which were located in/near the mountains or along the Japan sea coastline. They get huge amounts of snow every winter and the sodium chloride is used on the roads. Many cars have some kind of rubber like treatment underneath but they tend to limit it to the wheel arches underbody and fuel tank. Suspension arms and sub-frames will have similar corrosion to your JZX110 which is a common sight. See it all the time and car dealers here generally don't even mention it unless asked.

      new 1.5 LSD issues/concerns

      By Kinkstaah · Posted

      If the sound goes away when you clutch in, the 1.5/2 way diffs are just shit, and you are a normal person. The diff is likely "fine" but driving at anything under 30kmh is a violent horrible experience. It would be exaggerated with solid diff bushings and subframe bushings if you have those.
