Mitch's R33 Ls Track Car Rebuild

Recommended Posts

  • Topic Author
  • New diff and fuel system were fine but alternator has died on me. Picked up some slicks ready to mount on my now vacant 18x10s

    I’ve ordered a new alternator and a flat Nardi style steering wheel so I can use a quick release adaptor. I’ll put my old one in my dirt track 92’ corolla.
    Next big purchase will have to be a roll cage, hopefully in the next month. I want to stick with bolt in because I’m convinced I’m gonna put this thing in a wall at some point, just need to do some homework.
    Next race is 6 weeks away, enough time to make some new lca’s, get a wheel alignment and mount up the slicks

  • Got the slicks mounted up
    Shorter lcas made and fitted
    And a few other little jobs ticked off, replaced wheel bearing, tie rod boot. In for a full alignment Thursday and then BP sprint at Winton on Sunday

  • Alignment done just in time to load up for Winton
    Weather was threatening showers and storms possible all day but we had a pretty good day. In the top class Modified, turbo awd because of the slicks, the BP sprint runs a standing lap and three flyers and scored by adding you best of each for the day. Last time out here was a year ago on old semis and a heap of camber and I managed a 1:39. After the first session I was stoked to be P1 overall with a 1:33.4 flyer and a 1:40 standing. Obviously knew the car had a bunch more in it, taking it relatively easy on the first lap in particular.
    The car was basically faultless all day which was good because I managed to forget basically all my tools. I focused and learning how to get the best out of the new set up which I couldn’t fully master. If I remember some tool for the final sprint of the season next week I might check and play with tyre pressures also.
    I finished the day with a 1:32.0 flyer and managed to hook up and fluke a 1:36 standing lap which I’m stoked with. It was enough for 3rd overall behind two fellow club members in a 32gtr and SR20 Datsun. I’ll definitely be doing more of those days next year.
    The new wheels and tyres with a bigger overall diameter means some of the gear changes for this track have changed for my rig. Most notably, I wasn’t getting into 5th on the main straight but I think the engine may be slightly down on power from the last one. I’ll have to get it in for a tune in the off season and get a touch up. Despite being over 7 seconds quicker, coming onto the straight carrying a lot more speed and breaking deeper, the top speed was only 8km/h faster than last year.

    Great work. 

    What's up with the rear camber? 

    What's the format of these days like? How many stints did you get?

  • Cheers man, yeh i forgot to mention what rear camber i wanted but assumed he'd do what he thought was best. I guess he just didn't touch it. There'll be a couple more tweaks ill want done so it'll be back. It was occasionally breaking traction in the rear on some exits but it kinda chirped then gripping up again. May be a 'slick' thing coz they dont really squeal to let you know you're about to break traction like semis do or it may be a little too much rear toe in. 

    Format is excellent though, I'm thinking ill do all 5 next year if i can. Six groups according to previous lap times, grid up on the second straight and take off in pairs, drag to the first corner (or if you're smart, line up next to a mate and one takes off 3 seconds later) for 1 standing, three flying. Four sessions for points and there was time for a 5th so it was as much track time as the test and tune but apparently the numbers were usually higher.

    Rear traction may be locker + slicks? 

    As much track time but only 4 laps total in each session? That's only a 10min session or so max? I thought test and tune was like 20? 

    Will have to come along and just do one to see.

  • Yeh good point, still running a shimmed diff. Maybe it just felt like similar track time because there wasn't many wasted laps with traffic or having to do cool down laps to give the brakes a rest.

  • Had one last local track day for the year. Weather was bad but was due to clear up as the day went on. Only got one session and then had a severe fuel leak. The way we’d mounted the fuel cell had fouled and cracked the cell.
    Roll call turned up from agi, I went with a bit of a custom design, less crossbars and weight, x side bars, stretched front arms and side intrusion for clearance with no dash or door cards. I’ve gutted the car, will get some dry ice when I finally get a day off. One benefit of working crazy busy and not being able to work on the car is being cashed up for car parts
    Winton now requires race suits for all proper events so I’ll order one soon.
    Theres an event in two weeks that I could probably make it to in some capacity but I won’t commit until I get the cell back. Was promised end of this week but I don’t have much faith. Not too worried as the to do list is long;
    Must do -
    Fuel cell
    Then race
    Want to do -
    Sound deadening
    Roll cage
    Quick release wheel (need to find a slim hub?)
    Fit new front bar/look at aero
    Paint two black flares
    New brake pads or big brake kit
    Paint boot lid
    Mount wing better/stronger/higher
    Lexan 1/4 windows with naca
    Weight reduction
    Better driver
    Between this car an a vl beater I’d like to do 12 - 15 events this year

    Fuel cell welded up and modified
    New pads, the best money can buy
    What a shit job that was. Some of it came away so easy and some I just beat with a hammer
    Before the cage makes the job harder I’ve stripped out a bunch of unused ‘commodore meets Nissan’ wiring loom. Could still shed about half again but I want to race in about 10 days so it can wait.
    I’ve also removed the two black flares to be painted. Removed the boot to be painted. Sprayed the interior all black for now. Made new mounts for the fuel cell, bought a short steering wheel hub so I can run a quick release. Bought a race suit and sent it back because it didn’t fit.

  • So I’ve remounted the fuel cell. Car fired up and runs fine. Finished stripping the wiring loom and bolted in the cage.
    A little worried about the rear stay mounting bolts fouling the tyres. I’ll cut off the excess just in case
    Just a few little jobs to finish off before Winton BP sprint round 1 on Sunday.
    Oil change, new pads, change wheels. I’ll go back to semi slicks which puts me in class D, save getting my arse kicked by built 32 gtr track car on full slicks
