"fairly competitive"? gee thanks mate...

my suspension is a bit of a junkyard special.

FRONT: stanza struts, cut Gemini springs, redrilled lower control arm mounts, slotted strut towers, 120Y sway bar, Monroe shocks, urethane sway bar bushes

REAR: reversed short leaf, urethane bushes, 2nd hand Pedders shocks (were on my 1000 coupe when I bought it), 18mm sway bar.

it's nothing tricky, but it works together pretty well. I spent alot of time trying different springs, swaybar combinations, and leaf spring configurations (with wrecker/junkyard parts) before setling on what I have now. You should see some of the looks you get from competitors when they get a look under the car while you're changing wheels or whatever...

Every other front runner in my class uses adjustable platforms, race springs (I don't even know what rate mine are), adjustable and/or custom valved name brand shocks (Koni, Bilstein etc), adjustable camber. And they all have welded in cages as well, which most people will tell you gives some handling advantage by making the chassis more rigid.

The wider wheels and track promise alot of improvement. I only have the front flares on at the moment - ran out of time to do the rears before this event. I couldn't believe the difference it made, it was so tailly (loose/oversteer/whatever) I had to ge back to my old front wheels! Turn-in response was fantastic though. Can't wait to get the flares on the back so I can use the new 13*7 Superlites, but I will need stiffer springs all round I reckon, because the car is a little too soft even now - with the extra grip and corner speed it will need significantly stiffer springs and/or shocks to keep body roll under control. So I am looking at actually getting some proper shocks and stuff at the moment.

my brakes are a bit of a joke as well - 9.5" discs, and drums on the rear... I'll get to them one day too... then a rollcage would be nice...and then I could do Targa NZ or something. well, if I had the money!

Harry
I was wondering what type of suspension set up you use,,,,I have see you compete and find that you're fairly competitive but what are you up against in opposition??? Whats your view on this..??

Allan

Hehehe. Ok dude I will buy your old stuff first, see how I go.

Craig

Craig, how about I sell you my hand-me-down bits when I get the new stuff? gotta keep ahead of the competition

D, yeah the L16 block is the same height as an L18. no clearance mods required for the crank. the x-flow, twin spark NAPS (Nissan antipollution system) head has low and relatively small inlet ports, the included angle of the valves limits the cam selection etc. They are simply not used in Australia for naturally aspirated performance applications.

My engine only cost about $1400 to build, including buying the L18 bottom end, cyl head, manifold, carbs, machine work, clutch, rings brg and gskt. That was the main reason for going with the L series motor - cheap bhp.

that's the gearbox alright, tall 1st (i think 2.7 or 2.8) and 2nd (around 1.9) which also closes the jump to 3rd.

Anyone who wants to help save lakeside should keep an eye on this link for details of upcoming meetings etc

Hi Harry
Allan here I missed the event again due to work holding an outing on Saturday night and I didn't recover very well.....anyways good to hear you're still giving people a run will see you sometime another thing on 1st of April Nissan Datsun Club of Queensland are hlding a meeting at Albany Creek Library and I will be there on discussions about the future of the club and Lakeside.....anyone want to join its in the Yellow Pages under Clubs

Stevo keep up the good work mate I think you're gonna embarrass many more turbo friends of yours.
When last was your a series refreshed and what comp and fuel do you run?
Harry, the L16 is it the same height as l18? did you make room for the crank or did it fit straight in? have you considered the crossflow twin spark conversion for your L or is it not suitable?
Your right on the money about power and I prefer torque and a good mid range. Its great to hear of your feats it keeps me smiling to think that although cheap to buy dattos are getting expensive to do up. Well pricey for an a-series anyway.
The 1975 260z box I once had, had a long first and second which proved nice off the line and moved ahead of the pack easily.
Is that the kind of box the 240z has or is it all close in ratios?

Harry, good to hear you clocked some good times. Can't wait to get started on my little beasty so I can perhaps make the odd supersprint meet.

Oh yeah.....get friendly with fulcrum. Because whatever you get try that works I will have a crack at doing on mine.

Gotta keep up with the competition.

Craig

D

The red 260z with the 'sprint car' v8 beat cam by .200 of a second, but cam would have got him overall because they take your best daylight and best night time lap and add them to get your total time.

The 260z didn't do a night run

Just looking at the state round times from last year and i think it's time to enter up. I should be very competitive in my class.

by the way cam had 225/50/15 Dunlop Advans.......a long way from street rubber..........excuses excuses, but i beat him by 2 secs a lap at winton remember and hae only lapped 3 secs quicker on the power track. 84kw at rear wheels vs 190kw at rear wheels.

cheers

Stevo

I had a look at all the entrants on the running list last night, and it's probably more like somewhere between 13th and 16th outright out of the 85 entrants. Some of the fastest cars were dual entered...

my L series is 1770cc (L16 block with L18 crank and pistons) and makes around 120bhp at the wheels ~ approx 160bhp at the flywheel (estimated). But it consistently beats cars that claim to have much more bhp, and more highly developed suspensions. Even with the heavier L series, my coupe is still relatively light compared to the cars in my class. As I've said before dyno readings are really only useful as a tuning tool, or comparing cars run on the same dyno. I would like to do a serious cylinder head, and get a bigger lift cam sometime down the track, but only after I get a closer ratio gearset (240Z) for my box which should be in a month or two.

In May we will be running on the full State Championship circuit at Morgan Park, and I'll be able to compare my lap times to the Improved Production Circuit racers - that will be interesting

Harry out of 60 cars sh*t man thats a great result! I hate those clubmans bastards. They did the same to Stevo but he'll get there with some more hp in the straights. He told me it understeered a bit which is what Ive always heard of them doing cause of the little movement on the transverse leaf front.
Stevos mates 1600 sr20 is a brute and he ran with narrow steel rims and what looked like road tyres. Even my gal who knows little was surprised at how frightening fast that thing went and lapped some of the same group!. The straights favored the more powerful cars rather than the better drivers but it was fun to see stevos 1000 do so well with about 40hp less than Steve Newings old injected a15 1200.
harry how much is you l-series making? youre making me interested in that heavy donk
Stevo who got the fastest lap that night? I would have liked to have seen the your mates 1600 vs the lancia and the red 260z.
That Avanti lancia delta intregale passed us like I was accelerating backwards in my #### box work van on the Tullamarine freeway that night.
