redline make the best of everything. also, when you order it from perth or where ever they are it gets here overnight. I rang up one afternoon 4-5pm and it was at my front door when I woke up at 9am the next day.

Mate, She's the ducks guts...or the Smurf's gut's. Better give you a call.

Yeh Redline rocks and the water lines thing will be piss easy, but remember to bleed it...

I had a run at my first hillclimb yesterday.  It was the first round of the Tasmanian Hillclimb Championship and was held at Baskerville.  I wasn't expecting to go too well cause there was a bunch of Evo's and GTR's entered and it's pretty hard to make up the advantage they get off the line.  I didn't get a dry run all morning cause a shower would come through just as I got to the front of the line each time.  I still had fun playing in the wet though 

 

After lunch I had another wet run then the track started to dry out.  The next run I got a bit excited through the first corner and it was still damp which resulted in me going backwards while still at 6,000 rpm in 3rd    once the smoke cleared I'd done a complete 360 and was pointing in the right direction again so that gave everybody a bit of entertainment.

 

After that the rain stayed away and I got a few dry runs.  I soon worked out that 17x8.5 and 17x9 hard compound semi-slicks aren't the way to go for hillclimbs.  I couldn't get any grip at all and was suffering from massive understeer.  Still managed to get a couple of decent runs in but a long way from what I know the car is capable of. 

 

In the end I was very surprised to win my class and finish 2nd outright, a long way behind a very quick GTR and just 0.01 seconds ahead of a Cosworth powered Escort.  It's left me thinking I should run the rest of the rounds of the series but I've heard the next one is very bumpy so i'm not sure if I want to put the car through that.

 

Results from the day can be found here in the event results section:

There should be some photos up later in the week and I'll post the link.  There were 2 other Z's running.  A yellow & blue one and a very tidy original maroon one.  It even had a perfect interior and a dash with no cracks!

good result given your car is not setup as a hillclimb car - now imagine if it was 

[sco_aus]

Well done mate

[Scando]

I like my car soft so it's not too far off a hillclimb set-up.  I only run 200lb rear springs and a 16mm rear bar.  I reckon with some super soft tyres it would be a decent thing.

[bluerat]

Bloody engine machinists.....well done Bondy...the second track cant be any worse than some of the Targa Wrest Point roads, just wind her up a little?? I've got some long springs here as well if needed. You've been spoilt driving on tracks, welcome to the real world. You will enjoy round three, it's a ripper, but you will need a 'little man' tune up before hand, horse power rules at Highcleare. When are you posting the in car video evidence??

[Scando]

Pitty you couldn't make it Hodgo.  You've got a bit of work to do now if you're going to win the under 2L class again!

 

You're right, some of those Targa Wrest Point roads were pretty rough!  We didn't have the steam roller wheels on it then though, haven't got as much clearance now.  Like you say, I could always wind the ride height up a bit and make it look like a monster truck   If I do make it up to Highcleare it should have the new hair dryer on it by then.

 

The video from the weekend is still pretty average, more refinement of my camera positioning needed    I'll have a look at it and maybe put something up in the next couple of weeks.

Then under the Baskerville hillclimb heading click on "Click for photos by Paul Rice"

 

Check out the Maroon Z.  The photos really don't do it justice.  It's a very very tidy car.

Nice jigger!! It's amazing what comes out of the wood work, there were two different Zeds there last year as well, Mighty Mick's Yellow beast and the silver one. They are FAR from a rare car as many people seem to think. I live out in the sticks and theres two 260Z's, with different owners, less than 5 minutes drive from my place. Anyway...good luck next weekend champ, I'll pop up for the  day. How are you looking for a series win? What you need is a Chev powered, space framed 300zx, that would sort 'um out!!

You're not talking about Kerry Bailey's are you?!?!?!?!?

 

There was one better than that, Keith Carlings 300ZX, which may or may not be the same car, I'm not too sure. Keith ran the VG30DETT motor and in qualifying could dial up 1200hp to get pole. :o

 

The first tme the sports sedans ran at Bathurst in the late 90's it was a lot quicker up mountain straight than down Conrod as teh aerodynamics was unknown, the second year it was just quick everywhere once they worked out it wouldn't leave the road.

 

The Carling 300ZX would have to be in my top 5 of modern sports sedans, along with Ricciardello's GTV, The Saabs that Darren Hossak and Mike Imrie have built, Tony Scotts XJ jag.

I take it the rat sill isn't quite ready to go yet then?  Rumor is Cannan is real keen for the series win so if the supercar isn't fixed he'll pull the 930 out of the shed.  I reckon I should be able to beat him in the 930 but it won't give me much of a points buffer for when he gets the Supercar going again.  I'm not too concerned about the series this year.  More looking forward to getting the new snail and lumpy stick in and seeing what sort of lap times the old girl will do.

Sums it all up pretty well 

 

Kerry Baily is my dad's boss.  He's always been really good to me and sponsored me since I started racing karts when I was 8

He's been promising me a drive of the 300ZX for a few years now.  I had a couple of drinks with him friday night and he bought it up again so hopefully it'll happen.  1000kg and over 700hp on big fat slicks =  ;D ;D

 

It is the old Carling car.  It went like crazy with the VG30 but it was a hand grenade so that's why when Kerry rebuilt it he put the chev in it.

That and CAMS also made a ruling banning the VG30 from use because of the grunt of the turboed motor and how, when it didn't brake a 20 cent part, it just dominated the field and category.

 

The Chev has cetainly made the car more reliable, but the VG made it something special. Even so, a drive would be an unbelievable experience, especially on a power circuit like Eastern Creek, or as much as I don't like it, the paper clip up here in Brissie.

 

 

[Scando]

How did they change the rules to ban it?  I thought Voigt was still running a VG30 last season?  I reckon a twin turbo 350Z engine would be the way to go.  Just creeps in under 6 litres with the 1.7 multiplication.  Or have they banned turbos altogether?

 

He wants to bring it back to tas to have a crack at the Baskerville outright lap record set by John Bowe in a Ralt RT4.  So that's where I'll get a drive of it if he decides to do it 

 

 

 

 

[sco_aus]

Good work mate.  You seem to keep surprising yourself, so maybe this season is for you? lol

 

The next engine to watch will be the TRD 3.5 V6. They are the next 2J, totally off tap.  A friend is putting the non turbo 3.5 in his AE86, 200kw standard from the NA, so imagine the SC one with a little work... 

[garvice]

Off topic here, but 200kW is not a lot from a 3.5ltr N/A engine.

My 88 corolla had a 100kW out of a 1.6ltr engine, the 20V versions got up to around 120 odd kW

Honda got 184kW out of a 2ltr engine. Not trying to say that the TRD 3.5ltr engine isn't impressive, but those numbers don't seem real big for a 3.5ltr engine.

[bluerat]

Your a sharp man PZG!! It sure is a weapon!!  Didn't they ban multicam turbo's over 3 litres? hold it.....here we go...the 2008 CAMs manual...Max engine capacities are-Forced induction, multi valve 2520cc, two valve forced induction is 3529cc and multi valve N/A is 4615cc, two valve N/A 6000cc

 

The buggers!!

 

 

Hopefully we'll see Tassie's fastest bean counter in Tassie's fastest race car? (and Australia's fastest Datsun....)

Yeah, I reckon those supercharged Aurion's would be a ripper of a production car except they keep making them so they drive the wrong bloody wheels!  Hopefully one day they'll wake up and make them rear wheel drive.

The 4AGE is a great engine, especially for their time.  Get the supercharged version, get rid of the supercharger and add a turbo and they're an awesome little power house.  Don't take too much notice of power figures though.  On paper the S2000 should be super quick with 184kw in a light car.  But the problem is they have no torque and only produce power through a very narrow rev range, much like the Corolla Sportivo.  They're still very quick for a n/a 2 litre but not as quick as you might think.  And I'm sure Toyota could make oodles of power from the 3.5 litre 6 but you don't get a reputation for reliability like Toyota has by building cars that throw a leg out of bed after 20,000K's

Ah, makes sense, so you could still run the VG30ET out of the Z31's then.  Maybe that's what Voigt was running last year?  I wonder what you could get out of a 1JZ?  You really need a V6 rather than a straight 6 though to get the weight where you want it and still be within the parameters of how far you can move the engine from the original position.

 

lol, I guess KB's car would be the fastest 'new model' Datsun in Aus, which would also make it the quickest Z car in Aus.  Can't think of anything that would be quicker, not around a circuit anyway.

 

[Scando]

Just need to correct some wrong information on my behalf.  I just checked with the old boy and KB's car isn't Carling's old car.  He bought Carling's car, made moulds of all the panels, etc and copied some of the parts from the car.  But his car was built from scratch from a 300ZX (I remember him saying there's about 20KG of original 300ZX in it). When he was done with it he sold Carling's car to Voigt so that explains a few things.  I'll have to try to find out what engine Voigt is running in it now.

[sco_aus]

See there is the thing.  The 4AGZ/TE is a tough 4 cyl, but you will strugle to make more than 200rwkw after turbo.  The Aurion V6 is restricted a lot more due to much higher emission laws since the 4AGs.  People have already been pulling 400 fwkw out of the V6 without changing the internals, but here is the best bit, the engine ways about 20kgs more than a 4agze...  So imagine this thing with the SC motor (only about 10kg more on top)...    They rev and they a bucket load of torque. 

 

The other engine that should become more popular for conversions is the XR6 turbo motor.

Sorry to go off topic.

I know for sports sedans quite a few years ago the rules where changed that the any new 300ZX and one of the MR2 models could only run in Sports Sedans with retrictions on motor types. From memory the 300 could not run the VG30DETT, hence the going to a V8. I'm not sure whether Keith Carling's car can still use the VG or not. I think that would be up to an individual ruling from CAMS and what has happened to it, unless we wait for about 15 years and then it will be eligible to tun as a Group U car

[waxhead]

Interesting watching you guys talk about sport sedans

I help out on the yellow rx7 with the sr20 in it

the ervin car , we have just done alot of extensive work to it , its racing this weekend so we will see how it goes

[Scando]

People have already been pulling 400 fwkw out of the V6 without changing the internals

 

400kw@wheels in a front wheel drive.............Yuk!  I'm alergic to front wheel drives

I've heard historic sports sedans are becoming popular.  The other thing is, do they currently run under the sports sedan rules as per the CAMS rule book?  For the shannons nationals aren't they running under different rules with the Transam class cars from NZ?

Will be interesting to hear how it goes.  Wouldn't be easy to get the necessary power reliably out of an SR!
