    Evo 8 racecar

    So seeing as I never got around to making a thread up for my last car on here I thought I better do one for the new one so you guys can tell me how to build it properly.

    I had a beams powered AE86 which I was using for IPRA and some targa events, but there's only so fast you can go in an old corolla without spending stupid money, so thought i should sell it while it was still worth something and get into something which has a bit more outright potential for both IP and tarmac rally.

    I looked around for a while and after looking at several cars including a 'low km hardly used' evo 9 which was actually 3 cars joined together I found this:


    One ex performance car championship (GTP) evo 8 with some good bits fitted and only 1500km on the clock.

    The car ran in the 2007 championship, came 4th I think and was pretty much parked in a shed since then. I did some hunting around for the history of the car, didn't find much but I did manage to find a video of it running at bathurst which was pretty cool (and explains where some of the dents came from)



    So a mate and I drove over to vic and picked it up, complete with the paint from the wall at bathurst still on the front bumper.

    The plan is to give it a tidy up, (the old owner wasn't really big on cleaning anything, ever) remove as much weight as possible, build a motor for it and go race in IP for a while, with the potential to do targa stuff down the track if I get bored of circuit racing.

    Basic Rundown of the specs are:

    Sparco Chromoly Cage
    MCA Canister Suspension
    Ralliart Supertraction Diffs
    Autronic ECU
    Standard RS evo things like Close ratio gearbox, no deadner and windup windows

    Motor is still standard as per the GTP regs, so will need some rods and pistons asap to avoid ventilating the block with some boost once the restrictor is put in.

    I spent a few weekends cleaning off years of dirt, fitting new brakes and getting everything working on the car so I could get rally rego on it.










    Got it cleared last week so now the fun stuff can begin

    Shame on you for polishing off the genuine Bathurst scuff!

    I got it repainted as the spare I got with the car was in worse shape... I'm hoping to run it at the 12hr support race next year so it might pick up a couple more scuffs then haha

    If you go IPRA, look into gearboxes. They go bang bang bang bang bang bang when these things are pushed.

    God these things look tops all caged up in white

    I figure there's a few street cars putting 3/400kw through them and a lot of torque with strokers, so I should be ok with 250kw even with the extra torque from the restrictor

    All depends on how you drive them. They do transfers before they do boxes, and that's largely due to driver abuse etc.

    Streety certainly has had issued with them trying to pump that much torque so early in the rev range.

    SA is dominated by EMTs isn't it? How do you think you'll go against them?

    His is also the earlier evo box which isn't as strong.

    Should go ok I think, Mallala is very much a stop start track, so the awd grip should be better out of the slower corners provided the car isn't super heavy.

    Have a search for Anthony (Tony) Warren's Evo 7. That tends to run at the slightly pointier end when it is at the IPRA nationals. It also breaks gearboxes and transfer cases accordingly. I've been standing ~50 foot away from it when it dumped drive train all over the track

    IPRA turbo stuff has a totally different torque curve due to the 36mm choke of death. Jump on the IPRA forums and enjoy the reading about the 36mm chock of death Not trying to deter you or anything, just pointing out why a 250kw turbo 4wd car is going to pop bits if pushed in IPRA trim.

    I watched steve knight limiter sidestep his Evo race after race for a few year with only one breakage ( when he had his slicks on) gearbox will be fine.
    Should be a top 3 car around the lala

    Mallala may fade into history if Tailem Bend turns out as promising as it appears.

    true, but racing on a 7km track would sure beat a 2km track with only 8 corners.Worth more $$$ there for a start.

    Got a fair bit to sort out before it's race ready, aiming to have it done mid year.

    I highly doubt any state based race series will run on the full GT track. I even doubt the V8 $upercars will run on the full track.

    I hope it doesn't kill mallala. It's a challenging track.

    late model gearboxes are fine, a cooler is a good idea for long races though

    Yep, temperature is the main problem for Evo boxes under 300kw.

    Car looks great mate

    Got stuck into pulling this apart over the weekend, didn't quite have enough time to get the motor and box out so that will be a job for over easter.



    Need to work out where to mount it on the rotisserie as well because there isn't really any decent mounts at the end of the front rails, only 4 small bolts where the bumper supports hang off... Any suggestions?

    Put a sleeve inside the chassis rails and then use the small bolts to secure the sleeve

    Picked up the Rotisserie over the weekend and got stuck into things yesterday, was easier to mount up than I thought it would be, and it certainly makes wire wheeling seam sealer off the underside a shitload easier.


    Got about half done before I got sick of being covered in crap, will finish it off sometime this week.


    Also cut off some brackets with my new spot weld drill... how much easier do they make things!

    No it's not, I borrowed it off someone, but you can get them locally off ebay for about $600, which is really good value for how well they are made.

    Haven't had a lot of time to do much on this lately, but I managed to get most of the way through the seat mounts for the passenger side seat and cut up an old HRT door trim I had laying around to blank up the unused vent holes in the dash. I'll get the whole thing flocked eventually before it goes back in the car for good.

    Welded some threaded lugs into steel box section




    Seat height is nice and low


    Dash with panels glued into place, just needs flocking now
