Good man, just been doing what i can on it. not much more to do, but it does need to go in for a check up tune before i drive it. so, maybe 1 month

Ive been busy trying to pull more weight out of the car as im allowed to go to 1,113kg.

Bought a lovely FPR boot off Fatz that saved 6kg
Passengers door has been gutted with Lexan window, saved 10kg. im leaving the driver’s door intact until I have better side intrusion in the cage.

Partycat has hooked me up with some of his plastic headlight covers, which I am just going to mount in place of the headlights all together. Another 7kg
I needed a new battery for my rover so I stole the dry cell out of the this car and replaced with a 300cca li-ion bike battery. I think it’ll be enough to start it, but I’ll test it tonight. This saves 20kg… (dry cell = 20kg, li-ion =1kg and I can move the battery under the dash and remove some cable too)

I have pulled out the thermo fans and all wiring (and headlight wiring) 5kg and the hydro h/b is now gone too

I chopped up my old exhaust and made it into a side dumper. I cut out some of the rail and welded in some plate (I will also be making a strengthining member in the car) used some 4”x2” oval pipe about 40cm long to get as much ground clearance as I can, i will need to cut a hole in the skirt for it. 10kg save here too

New engine belts are on too, so I should be able to give it a kick in the guts tonight and see if ive connected everything up right.


So, that’s nearly 60kg gone this time around J just need to get my fat ass to the gym and save even more!

Next weekend I will be modding the rear subframe so I’ll actually be able to change the static camber, rather than adjusting ride height to get what I need. Semi trailing arm IRS sucks….modify_inline.gif

basically you need to put a vertical slot in the outer subframe mounts where the trailing arm bolts up, then you can use and eccentric bolt for adjustment.

its the same as what the factory did with the inner mounts, except they were horizontal, for toe adjustment. i have no idea why they didnt do it in the first place!

haha thanks.

i think weight will be my only advantage as I think i will be lower on the power side to most other cars. that, and the suspension and geometry isnt that great either lol

Didnt get much done this weekend, or pics for that matter.

The new battery is in, and starts the car just as well as the old one. just not sure how many starts i get smiley.gif Also removed 3kg of battery cable, 23kg total!

dad made a bit of extra chassis inside the cabin to support where the rail was chopped for the exhaust. he went a bit overkill but thats dads for ya lol

filled in the hole in the boot where the spare wheel well was.

"headlights" are fitted up, just need to be wraped.

Looks pretty good i reckon

  • Like 1

thanks guys. yep anth, ty hooked me up. i did need to do quite a bit of work to get them to fit, as he could only pull them down so far with his mold. came up well though i think.

Moar done this weekend smiley.gif im only really able do stuff on the weekends as I have to put some time in with the family during the week lol


Had a go a vinyling the headlights, looked quite shite as it was old stuff and didn’t want to go on.
Ended up just spraying with some rc shell paint, came up pretty good

Cut off the old standard tow point and relocated the tow hook to the chassis to make room for the diffuser


2013-08-19073751_zps83a0618d.jpg




New harness is in as I needed 2in webbing for the HANS. Also the old belt was out of date.


2013-08-19073911_zpsdd408804.jpg



Annnnddd finally got the nerve up to mod the subframe for camber and am very happy with the result, all done for zero dollars J
I followed this guide ( for z31)http://www.az-zbum.com/modification.adjustable.camber.shtmlwith a couple of variations.


2013-08-18111912_zps2848df74.jpg



We (Dad and I) didn’t like how much ‘meat’ was left after slotting the pickup point and so added some more metal


2013-08-18115013_zps3bf134f6.jpg



I couldn’t find any toe adjuster bolts to buy so we just made some cam washers and keyed the existing bolts to suit.


2013-08-18111931_zpsbdc3fd25.jpg




The overhang at the top are the blocks to hold the cams in place, not pretty but they work.



2013-08-18130110_zps9a3323a8.jpg


I set it to max camber and toe out to see how much adjustment there will be, Hard to see in this pic but they are currently sitting at -1deg camber and 0mm toe uncelebrated eye measurement. Camber was around -4 -5deg. hopefully should translate into more rear grip.

I want to set the rear to (static) -1.5 deg camber and 1mm total toe in and go from there.

Im going to try and finish the little bits during the week and also book it in for the retune. Next wend i'll be making the rear diffuser.
I dont know it this shows well enough but you can see the difference of the rear camber/tow to the front. there is a full inch on both rear tyres that never get dirty... will still be shite trailing arm irs but a little less "oh your comfortable? well let just mix things up and BAM!, sidways" lol

Thanks Mungy :)

More progress

One piston on the rear right calliper has seized at some point and has been pushing the rotor into the calliper, So I rebuilt the rear callipers during last week and bled the system on the weekend. Very happy as I made my own line from the bias adjuster to the rears after I removed the hydro. Pedal is a lot firmer than it has been in some time smiley.gif Also gave them a paint to match the fronts.

Rolled out the car to bleed the coolant, bought a cool vacuum purge kit to do it but my air compressor is piss weak. Ended up doing it the old fashioned way, by raising the front and running the car. This led to another issue, ive have to rev the car to 2500rpm to get the alternator to kick in, now with the underdriven pulley its has to go to around 3500. Didn’t know this and ran it off the tiny battery. lasted about 10 min and wouldn’t restart, lol… quick jump start and rev and the battery charged itself enough in a couple of minutes to be able to restart again.

Made the rear diffuser, out of a scrap - 31life, but I think it’ll work well. Goes from the subframe, sticks out about 50mm past the bumper and has a 9deg upswept angle. just needs the rear mounts to be made. Again not many pictures as I only have so much time to get everything done on the wend. I'll get a pic tonight of it on the ground.

Well yesterday was a mix of good and bad. (above is just a bad taste pic as they were visiting the neighbours)


First up was a wheel alignment, Camber mod is a success, the rears are sitting at -1.5 deg camber and 1mm toe in. Front is -4 camber, -5 castor and 1mm total toe out. I’ll probably dial out some more front camber at the track, but is fine for slicks atm.


2013-08-27111515_zpscfe4264d.jpg


Then off to ESP for a check-up/tune. Quick reset of the timing and roll up on the dyno, and the wastegate failed. Leaking boost again and over boosted too 21psi before the boost cut, cut in. looks like the valve shaft has worn and is leaking there.

Mate took a video of it running, i think it sounds awesome. as soon as he sends it to me i'll post it up smiley.gif

The guys at ESP have also recommended that the gate is too small for what im doing with it now, so ive bit the bullet and bought a new Turbosmart 45mm HyperGate.
now i need to either mod the new manifold to suit or sell it and buy another.




2013-08-27152602_zps7c3ba306.jpg



Hopefully it’ll control the boost better now and be the end of my wastegate issues. Silver lining here is at least ive found out now rather then at a trackday or wtac.




quick snap of the diffueser in place

Basiclly the washer is just a 4mm bit of metal, cut round with the hole drilled offset to match the OEM ones. then you have to mill/grind/file a flat section on the the thread of the bolt and put a weld in the hole of the bolt and file flat to match the bolt. will look like a 'D' shape. this is done to 'lock' the washer to the bolt.

good progress on this am liking it

with the eccentric bolts did u just drill and tap a thread into the washer?

was wonder how to make up my on eccentric bolts without getting the bolt and washer milled

    • Seat of the pants assessment of the new intake: The car is way less "doughy" when hitting the loud pedal, especially off idle when stopped or in traffic, I did use a cheapo lazer thermal thingo to measure the temp around where the pod filter got its air, it was between 55 - 60°C, in saying this the car was shut off and not moving, so the OEM intake pipe was not supplying any fresh air to where the pod was when the car was at least moving A weird bonus was induction noise on the throttle in the cabin increased a bit,  I was worried that I was actually going to lose some of that induction noise I love so much, outside though, when I got the daughter to do a WOT drive by pass for me, the induction noise has increased alot when on the throttle, not quite ITB doort, but well up there I'm extremely happy with the results and have been exploring the country roads in the region  As for house mods: 1.New front fence is up and is awesome, it really upgraded how the joint looks from the street, and the added security is nice 2. Electricians have replace some interior lights, and with more lighting in the garage, a few new motion detecting lights out the front above the garage, front room, and at the front door, which I have already found heaps helpful coming and going, also now has fancy pants CCTV all round the house The only hold point for power though is the solar and batteries due to supply issues, although this will happen over the next few weeks 3. I have done a heap of landscaping out the front and I'm almost ready to do a new small retaining wall with some nice blocks to replace the brick and cemented in rocks around the raised garden beds cemented in river stone "was the fashion at the time" the house was built. I currently have a pallet of retaining wall blocks and 2 bulka bags of 20mm blue metal to replace the wood chip that is in the raised garden beds around the house 4. I now have 3 big raised garden beds for out the back to grow some vegetables, about 70cm high, 200cm long and 100cm wide 5. My 2 compost bins are already pretty full with brown, green and kitchen waste from the landscaping I'vedone so far, but they will probably take a few months to break down, so anything else that gets chopped, trimmed, and kitchen waste will just start filling the base of the raised garden beds to about 30cm before I start throwing 40cm of good compost, and stuff, for the vegetables to grow in, I'll need a few ton of compost and soil, but the local supplier can sent me bulka bags of the stuff Basically the logs, wood chips and a few strategically placed rocks for drainage, will give the beds some good organic materials down low to break down over time, and they will hold moisture during the warmer months to save the water in my big arse water tank if we don't get alot of rain So, all in all, the car and house mods are going well, and I'm really enjoying being retired, I sleep in too 0700 and slowly plod around inside until I feel like actually doing anything, and only work in the yard for as long as want, which has actually been alot over the last few weeks,  although when you look at it, it seems that not a huge amount of work has been done,  until I look at the before I started the work pics Happy days and good times indeed 
    • hahaha yeah. Plan is to get side skirts and probably just rear pods. But going to do them one-by-one. I've got a set that I really like from RHDJapen, but that one isn't shipped to AU. So need to find someone who can get it for me
    • Here's an idea, answer the questions I asked you as they are trying to work out WHY the LSD will be binding up in a straight line.
    • You haven't driven many modern cars then have you? Most of them have sfa steering feel with their stupid electric bullshit steering systems.
