Lurch's 240Z Racecar

Recommended Posts

Posted (edited)

I said to a fellow forum member last year (2018), that if a suitable Z race car came up for sale, I'd seriously contemplate purchasing one.
Then late last year, I received a call from said member:
"Lurchos, I just got off the phone from Noel Edwards - he's retired from competition and is looking for a new owner of his 240Z race car. I straight away though of you! You better call him ASAP."
Me: That's REALLY tempting mate. I'll give him a call now...
(Note: I'd had a little bit to do with this Z a number of years ago via Peter Mac of PMC Race Engines).

I manged to contact Noel, had a quick talk, and Noel said it was in storage - he'll get it out and down to his mechanic in a couple of week so I can view it.
A couple of weeks later I went and viewed the Z with Noel, however while the Z checked out, Noel hadn't settled on a price - much to my frustration...
A week later Noel and I came to an agreement on price, and a couple of weeks later I picked it up:

IMG_20190217_112338512.thumb.jpg.56426bedb2d23569e8031cbc79f4a3f0.jpg

It was originally a very basic club car in NSW, before Noel bought it down, and over the next 10 odd years upgraded it a LOT...

Specs are:
'73 HS30 all steel body
Stripped interior
Bolt in full cage
Sparco seats & 5 point harnesses
Racepak Dash
F&R spoilers

Adjustable suspension (konis & coil-overs)
Adjustable suspension arms all round.
AZC Wilwood brakes all around.
Wheels are Simmons FR17's wrapped in Khumo V70a 225/45/17 Semi-slick tyres.

Peter Mac built, injected 2.9ltr
All the good internal parts.
EFi Hardware TB's controlled by a Haltech
E85 fuel
Kamerari gear-set kitted S14 71C gearbox
R200 LSD Diff (still need to confirm ratio)


Punches out 187kw at the rear hubs (approx 315hp @ flywheel)

It was a street car that I used to supersprint. If it's still the original LSD then it's a 3.7. Since your tracking it you can run a 4.1 pretty easily. 

 

I put the coil overs and adjustable suspension in it and put the injection rail on it. 

 

The motor was 2.95 litres when I had it. L14 rods bored out and a ported P90 Head. 

 

Good to see it still kicking around! Will try and find some old photos

I thought it looked familiar I remember it as a street car when you owned it Brett. Didn't you go to Swinburne University around early 2000s?

I remember I would catch the tram in and sometimes see it when waiting for the tram.

I seem to recall it needed rear 1/4 panels at 1 stage?

Ohhhh that's my old car! I could probably still answer a lot of questions about it if you have them.

Ya kidding, Brett?! Jeeze this Z community is small!!!
Yes definitely send me some more photos (I'll PM you my email) I'd love to add them to my album.
It's had a few changes under Noel's ownership, but obviously not as much as I was let to believe...
The diff is supposedly a 4.375 LSD now, but I'm not convinced. I have another 4.375 LSD I've recently had built, so I'll be swapping that in, in due coarse.

4.375 will be great if it is, you'd run out of revs at Philip island and bathurst with it though. 

no probs send it through. i have photos from when she was a bone stock road car as well. 

the differences i can see form when i had it are the cage and interior strip out, plus if it has willwood brakes now then those have changed, plus theres been some work to the injection system. i had 300ZX vented fronts an AU falcon rears on it. 

the spolier and wheels i put on it, though i used lighter 16 inch rims for the track. 

 

Will have to change my profile pic now that the new owner has turned up!

I've actually changed the gearbox to a Nissan 200SX S14 '71C' gearbox with a Kameari Ultra-Close-Ratio gearset - 5th is 0.75, so a 4.375 diff ratio will give it plenty of legs.

The old gearbox (which I still have) I believe is an FJ20t unit - but the shifter knuckle was so worn out, I kept getting 3rd instead of 5th out on the road. 
Wouldn't be desirable situation on the track...

I remember when it had the old brake setup, as I replaced the under-floor chassis rails in it around 2010/2011 for Noel.

So after taking possession of the 240Z from Noel, a few things had to happen:
*New drivers 5-point Harness.
*Move the seat back - I'm 6'4" and Noel is 5'7" wringing wet...
*Change the gearbox - see above or reason why.

So with these items completed, I entered for P.I. on the 27th of April with the MSCA.
It dawned a perfect Autumn day, cool but clear - perfect for good lap times.
Unfortunately it wasn't to be... On only my 3rd lap, getting used to the Z and bringing the tyres up to temperature,  coming up towards Hayshed
the engine dropped onto 5 cylinders.
Upon returning to the pits, we diagnosed a dead coil-pack. Without any spares or any locally available replacements
(a genuine GM LS1 coid pack is required) I packed up and drove home :(

Also during the first couple of laps, I wasn't convinced it was performing 100%, so I felt a dyno tune was in order...

A few weeks ago, after replacing the coil pack (and ordering a spare!) I booked in with my local Haltech tuner, so make sure everything was in order.
Long story short - it wasn't. 

We cleaned the injectors, new fuel filter and spark plugs. Then we strapped it to the hub dyno.
Some fuel and ignition map inaccuracy's were discovered, but thankfully the tuner put it all right.
Peter Mac also stopped by to lend a hand and adjust the cam timing.

At the end of the afternoon, it netted 187kw at the hubs - quite healthy for a 2.9ltr!

Sandown was the next outing as per the thread here: 



Unfortunately failure was rear it's ugly head again, when my best mate Alex, on his 2nd session - came crawling into the pits unable to select gears.
Upon jacking it up we found the slave cylinder was working, but the clutch wasn't releasing. We couldn't do anything else so by late morning we packed up and headed home - defeated.

WTF?! Is this thing cursed?!

We removed the gearbox and clutch this afternoon, and found this:

IMG_20190609_150728622.thumb.jpg.e580d5e1da7ca79fd4d21576cb82ba95.jpg

After speaking to Les Collins I learned some new things about clutch's...
An upgrade is on the cards!

You managed to keep that well quiet mate!

Car is awesome, sounds so good howling down the straight. Bummer for the clutch issue but gearbag should be sweet which is the main thing.

Kudos to you sir.

I think if I get another, it will need to be a dedicated track car. :D

Nice power! Especially given the weight of a Z.

Sorry, got it confused with another orange Z. I do remember seeing it at the Nissan Datsun Nationals in 2005 though!

 

What I find scary is that it was nearly 15 years ago! Yikes..

That car got me into Z's, Brett and his brother are friends of my son and when he turned up at home with the car it rekindled my appreciation of the Z and I bought my first one a 240 in 2000 for $2500! and later i purchased my 260 which i have now.
