Not sure about the scrub radius... I lengthened the control arms by 25mm to get 2 1/2 degrees of Negative Camber, I guess it would have widened the track by about 60mm... normally you would want the rear track to be wider than the front, so ideally would swap the rear wheels to something with a deeper dish, but I won't bother...

Since the ball joint remains in the same location relative to the strut, wouldn't scrub radius remain the same???

I went 2 1/2 degrees because of the locked diff, 2 degrees would be plenty without that... it has helped enormously with turn in... At the same time I went to R31 Steering arms to quicken the rack up (effectively shortening the steering arms by about 12mm), so with the effect of that on the Ackerman, I can't be sure of what would have driven any change of feeling...

Instead of lengthening the control arms, the ideal would be using 240Z tops, and smaller springs, and relocating the bolt holes at the top, so you could get the Neg Camber without widening the track... but that is a lot more money than the car is worth...

I was going to use R31 Lower Control Arms so I could replace ball joints, but I would have needed to lengthen them by about 75mm, and there didn't seem to be an easy way to do that...

One day, I will probably get the caster rods machined up to be adjustable so I can adjust the caster...

well the scrub radius is the line from the top pivot point ie the strut top mount and the bottom pivot point ie bottom ball joint and where that line will meet the road compared to a line through the centre of the tire to the ground, this is to give you steering feel, if the top mount is standard and the bottom ball joint has moved out it will effect this, however it could be a good effect so thats why i ask? if you have plenty of road feel through the wheel it must be working well.

I think the scrub radius will be the same... The distance from the line through the ball joint to the strut top to the centre of the wheel is the same... to change the scrub radius you would need to change the line...

I think 240K/180B Steering arms have the ball join centered in the middle of the strut... R30/R31 Steering arms have the ball join set outwards in the strut... changing from a 240K to R31 Steering arm would change the scrub radius... but that offset is the same for R30/R31 that is swapped between...

Is that right???

Just a bit of an update...

Our club is running our Wakefield Park Supersprint on June 20th. They won't let me run the white car because of the 'excess body damage' so I am going to try and get the green car ready... this is a car that has only been driven in the driveway since I bought it, so I have no idea what I am going to find...

I have disassembled and reassembled the gearbox with help from my mate Warwick... only ended up replacing a couple of bearings, and the front housings... didn't put the Zed first gear in, 'cause I decided it wasn't worth the hassle, and with a 4.8:1 diff, the gap between 1st and second gears is less apparent anyway...

I bought a ceramic button clutch for it, and have installed the clutch pedals, but that is about it... At the moment the car is on jackstands without lwer control arms, rear suspension, geabox, or diff

The list of things to do;

A Has to be done

B Should be done

C Would be nice

D If you have time

E Must be bored

A Buy & Fit Fire Extinguisher

A Fit 2nd Throttle Return Spring

A Fit Clutch and Gearbox

Hi Daewoo,

Just wondering... you've converted an auto to manual, does a manual R30 have the same ECU as an auto or are they different?

JH

Hope it is the same, or I am screwed - don't think I kept the ECU from the manual car I had before I sent it to the big scrapyard in the sky...

hey daewoo

do any of your cars have grey interiors?

i need some door handles and door handle surrounds ?????

cheers

Hopefully someone here will know for sure.

Also, I read somewhere that the auto flywheel is different to the manual. Didn't see flywheel in your list.

Sorry, both were brown...

Auto's have a flex plate that the torque converter bolts to... I have the flywheel from the car I pulled the gearbox from... needs a bit of a clean up, as it got a bit wet in the shed when I had it stored... but it will do...

Cheers,

Daewoo

how do you get into this stuff? barely looks legal haha

Neither car will be road registered... the locked diff and welded lower control arms put paid to that... the number plates are old ones that I never handed in... I just had them on the car when it was parked on the street to stop the council sticking a 'Tow Away' sticker on it...

The white car is barely legal for competition - I always check with the organiser that they will let me run without a grill and headlight... other than that it is OK, no sharp edges which is something they are always obsessed with...

The green car is a good car, and could be registered if I hadn't started doing mods that exclude it... but who wants to pay $1,000 per year for a car that is never driven on the road... you don't want to drive it to events, because you never know if you won't be able to drive it home :lol:

For $500 each, I reckon they are bargains... :) definately had more fun with them than the $30K Pulsar sitting in my mates chook shed...

Cheers,

Daewoo

Sounds like fun, As Wakey is only an hour a way i will come say gday...

maybe add perspex rear hatch to the list? have you felt how heavey they are!!!! i cant lift it on my own (almost)

my red parts car is about 1m in the air right now getting GUTTED. so I'll have a few years worth of spares.

the auto ecu will work with the manual, and so on. main differences between the 2 engines is the distributor. one has a different advance curve to the other.

also I have a 3 inch exhasut here you may be interested, its got surface rust, mild steel . but I wont be useing it as I have a 3 to 2.75 inch mandrel bent stainless system going on.

as I have a 3 to 2.75 inch mandrel bent stainless system going on.

Where you dig this up from?????

Though you might want to rethink this as I think a 3" system on your L24et will be detrimental to an 2" or 2.5". You have to have free flow in any turbo system and very nearly zero back pressure and restrictions, but 3", I don't know about?

The next Khanacross I was aiming for is the State round on May30th at Awaba near Toronto near Newcastle... but... I am also trying to get my other, undammaged MR30 ready for a Wakefield Park Supersprint on June 20th... so it very much depends how that is going whether I will go to Awaba...

I missed the first 2 rounds of the State Championship already (Overseas for the first, and had trailer problems for the second) so I am pretty much out of the running for the Champs, and I want to see how one of these will go on the track... They are good fun in a Khanacross, despite being fat and underpowered... if you get them singing they are good value...

This knancross and what not is something I'm really keen to have a crack at one of these days, I have enough cars around the place I can use, I just always seem to be too busy. Building cars then fixing them all for mates none of my own cars.

Gonna have to look into it

    • The average previous owner for these cars were basically S-chassis owners in the US. Teenagers or teenager-adjacent. I often tell people that neglect is easier to fix than something that was actively "repaired" by previous owners.
    • Update 3: Hi all It's been a while. Quite a lot of things happened in the meantime, among other things the car is (almost) back together and ready to be started again. Things that I fixed or changed: Full turbo removal, fitting back the OEM turbo oil hardlines. Had to do quite a bit of research and parts shopping to get every last piece that I need and make it work with the GT2860 turbos, but it does work and is not hard to do. Proves that the previous owner(s) just did not want to. While I was there I set the preload for the wastegates to 0,9bar to hopefully make it easier for the tuner to hit the 370hp I need for the legal inspections that will follow later on. Boost can always go up if necessary. Fitted a AN10 line from the catch can to the intake hose to make the catchcan and hopefully the cam covers a slight vacuum to have less restrictive oil returns from the head and not have mud build up as harshly in the lines and catch can. Removed the entire front interior just shy of the dashboard itself to clean up some of the absolutely horrendous wiring, (hopefully) fix the bumpy tacho and put in LED bulbs while I was there. Also put in bulbs where there was none before, like the airbag one. I also used that chance to remove the LED rpm gauge on the steering column, which was also wired in absolute horror show fashion. Moved the 4in1 Prosport gauge from sitting in front of the OEM oil pressure gauge to the center console vents, I used a 3D printed vent piece to hold that gauge there. The HKB steering wheel boss was likely on incorrectly as I sometimes noticed the indicator reset being uneven for left vs. right. In the meantime also installed an airbag delete resistor, as one should. Installed Cube Speed premium short shifter. Feels pretty nice, hope it'll work great too when I actually get to drive. Also put on a fancy Dragon Ball shift knob, cause why not. My buddy was kind enough to weld the rust hole in the back, it was basically rusted through in the lowermost corner of the passenger side trunk area where the wheel arch, trunk panel and rear quarter all meet. Obviously there is still a lot of crustiness in various areas but as long as it's not rusted out I'll just treat and isolate the corrosion and pretend it's not there. Also had to put down a new ground wire for the rear subframe as the original one was BARELY there. Probably a bit controversial depending on who you ask about this... but I ended up just covering the crack in the side of the engine block, the one above the oil feed, with JB Weld. I used a generous amount and roughed up the whole area with a Dremel before, so I hope this will hold the coolant where it should be for the foreseeable future. Did a cam cover gasket job as the half moons were a bit leaky, and there too one could see the people who worked on this car before me were absolute tools. The same half moons were probably used like 3 times without even cleaning the old RTV off. Dremeled out the inside of the flange where the turbine housing mates onto the exhaust manifolds so the diameter matches, as the OEM exhaust manifolds are even narrower than the turbine housings as we all know. Even if this doesn't do much, I had them out anyways, so can't harm. Ideally one would port-match both the turbo and the manifold to the gasket size but I really didn't feel up to disassembling the turbine housings. Wrapped turbo outlet dumps in heat wrap band. Will do the frontpipe again as well as now the oil leak which promted me to tear apart half the engine in the first place is hopefully fixed. Fitted an ATI super damper to get rid of the worn old harmonic balancer. Surely one of the easiest and most worth to do mods. But torquing that ARP bolt to spec was a bitch without being able to lock the flywheel. Did some minor adjustments in the ECU tables to change some things I didn't like, like the launch control that was ALWAYS active. Treated rusty spots and surface corrosion on places I could get to and on many spots under the car, not pretty or ideal but good enough for now. Removed the N1 rear spats and the carbon surrounding for the tailpipe to put them back on with new adhesive as the old one was lifting in many spots, not pretty. Took out the passenger rear lamp housing... what do you know. Amateur work screwed me again here as they were glued in hard and removing it took a lot of force, so I broke one of the housing bolts off. And when removing the adhesive from the chassis the paint came right off too. Thankfully all the damaged area won't be visible later, but whoever did the very limited bodywork on this car needs to have their limbs chopped off piece by piece.   Quite a list if I do say so myself, but a lot of time was spent just discovering new shit that is wrong with the car and finding a solution or parts to fix it. My last problem that I now have the headache of dealing with is that the exhaust studs on the turbo outlets are M10x1.25 threaded, but the previous owner already put on regular M10 nuts so the threads are... weird. I only found this out the hard way. So now I will just try if I can in any way fit the front pipe regardless, if not I'll have to redo the studs with the turbos installed. Lesson learned for the future: Redo ALL studs you put your hands on, especially if they are old and the previous owners were inept maniacs. Thanks for reading if you did, will update when the engine runs again. Hope nothing breaks or leaks and I can do a test drive.
    • No those pads are DBA too  but they have colors too. I look at the and imo the green "street" are the best.
    • I’m not sure what happened I told them about sonic tunes free OTS tune and the next the I know .. I was booted..   To funny
