My mate rally's a 240K Coupe (and does very well)... back when he first started we were ribbing him about his choice of whale, and he stated "It's a Materpiece" and started to be called The Masterpiece.

Another mate then bought a 4 door K, that, because it had four doors was practical, and became known as The Practical Masterpiece...

10 years later I found myself owning the white MR30 Hatch for a khanacross weapon... It was smashed in at the front, but had the TI wheels, which are the only thing of value... I got a new guard and and bonnet for free, inserted a welded 4.9:1 Diff, and it is now The Pratical Materpiece EVOI...

I have the lower control arms out to get them lengthened...

I wanted a manual, and because of the panel damage am not allowed onto race circuits, so when another 2 MR30s came up on fleaBay for $500 I grabbed them... one was a front end damaged sedan (unfortunately the same side) that had all the wiring and interior eaten by Mice, but had a good engine and manual gearbox... the other a good hatch with a blown headgasket... This is Now the Practical Materpiece EVOII

I stripped the sedan of all the bits I wanted, and sent it to the scrapper... I stripped that back half of the interior from the hatch, lengthened the lower control arms by an inch to get more camber (and turn in required because of the locked diff)...

The idea is to keep competing in the EVOI until the EVOII is ready and then the EVOI will become a loaner thrasher, or donor car...

The springs are heavy but too low for a dirt circuit car, so I will get some new ones from all springs... I have a Cresida AFM to fit up, and a 4.9:1 crown wheel and pinnion I need to pick up... next step is to convert it to a manual, probably using a 240K box, because I can get one for nothing...

Just had the cars at home in the driveway, so thought I would post up a couple of happy snaps...

Cheers,

Daewoo

love your projects! we need some race pics and results

Next race is on April 11, I will try to get some photos or video...

As for results, there are a few other guys who have the same idea as me, have lots of fun without spending any real money... they have mostly chosen R31 Skylines, and the car is as fast as theirs... I have the traction advantage of IRS, and slightly less weight... they have a big horsepower advantage...

I am also limited because the Auto trans in my car will not go back to first if I kick it up to 2nd, so I spend a lot of time bouncing off the rev limiter in 1st, because I need the power to keep the tail out on the slower corners that Khanacrosses are mostly about...

HAH!!

I like the naming convention!!! I might adopt a similar one?

What would you call a MR30 Ti Hatch, soon to be boosted?

and can you post up the lokation for the Arpil 11 event? i have a bit of time off then, never been to a gravel event (to spectate)

Hopefully mine. I want to RB25/30DET one of them one of these days...

I'll PM you the details, it is our club only event, and the site is a bit confidential, less 'hoons' get out there and f^ck it up... if you have a car that you want to play in, it is only $40 to join the club (9 months) and $55 for a 12 Month CAMS Licence available on the day. Once you have paid that, each entry fee is either $25 or $35 I think...

Did you say auto? You're 'racing' a 3 speed auto MR30?

Yeah... Auto :D ... it is still good fun tho... but hopefully I will get around to the conversion as soon as I can find a 240K box for free or near to...

man thats awesome, i have an R31 im about to mod for rally, only prob is thats its a 4door... oh well
What's wrong with that? There's a very quick 4 door R31 doing the club rounds up here in QLD. It was built on a very tight budget too
where do u get ur 15" rally tires from?
Everywhere. All the big players use them once then sell them off cheap-ish. These days most of the competitors run 15's, so that's the biggest choice in tyres out there. In fact, I have a set of used A035 195x65 15" rally tyres I might be selling off in the near future (depending on how well they fit in the car).

I guess your problem is that you build up a four door, and then will always be wishing you started with a 2 door for the looks, which is valid enough... make sure you read up on the rules for whatever sort of rallying you would like to do, because unlike drifting the rules are quite specific, and limiting to what mods you can and must do...

oh well where do u get ur 15" rally tires from?

I just buy them from the Motorsport Tyre suppliers, Dunlop - Gary's Motorsport Tyres... they sell limited numbers of second hand tyres... but you can also buy them directly from a number of teams...

Pretty much everyone uses 15's...

Also, I find 4 doors more practical for rallying, specially if you mount battery, spare tyre, tools etc, in the cabin (as opposed to the boot). If you have a 2 door, the rear passenger area is pretty much useless with fixed back rally seats. You'll be surprised how much gear you store in rally cars.

Great pics and looks like fun. Is the sedan also an auto? The sedan should have a weight advantage over the hatch.

JH

No - Buggsy is a cheat - he has a manual gb - cheater

I have a weight advantage, cause I don't have a grille or headlights :P and I'm not a fat bastard :happy:

That said, I am on my way to Karella Gearbox Factory (what we call my mate Warwick who is pretty good with gearboxes), with my MR30 box with a f^cked front housing, and a 240Z box with good housings and good ratio gears but f^cked synchros to see what magic he can weave for me...

I have some DVD Footage from the weekend, but it is in .VOB format (video) and I think I need to convert it to post on YouTube...

Hey Daewoo,

about lengthening your bottom arms.. i saw this in a previous post as well and wanted to ask how much by and with the track change what effect did it have on steering feel? i assume it would effect scrub radius?

Marc

Hey Daewoo,

about lengthening your bottom arms.. i saw this in a previous post as well and wanted to ask how much by and with the track change what effect did it have on steering feel? i assume it would effect scrub radius?

Marc

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...

Cheers,

Daewoo

    • Hi, is the HKS  Tower Bar still available ? negotiable ? 🤔
    • From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.
    • Place the new daughterboard in the case and mount it using the 3 small black rivets provided, and reconnect the 3 factory ribbon cables to the new board Then, use the 3 piggyback cables from the daughterboard into the factory board on top (there are stand offs in the case to keep them apart. and remember to reconnect the antenna and rear cover fan wires. 1 screw to hold the motherboard in place. Before closing the case, make a hole in the sticker covering a hole in the case and run the cable for the android unit into the plug there. The video forgot this step, so did I, so will you probably. Then redo the 4 screws on back, 2 each top and bottom, 3 each side and put the 2 brackets back on.....all ready to go and not that tricky really.      
    • Onto the android unit. You need to remove the top screen because there is a daughterboard to put inside the case. Each side vent pops out from clips; start at the bottom and carefully remove upwards (use a trim remover tool to avoid breaking anything). Then the lower screen and controls come out, 4 screws, a couple of clips (including 3 flimsy ones at the top) and 3 plugs on the rear. Then the upper screen, 4 screws and a bunch of plugs and she is out. From there, remove the mounting brackets (2 screws each), 4 screws on the rear, 2 screws top and bottom and 3 screws holding in the small plates on each side. When you remove the back cover (tight fit), watch out for the power cable for the fan, I removed it so I could put the back aside. The mainboard is held in by 1 screw in the middle, 1 aerial at the top and 3 ribbon cables. If you've ever done any laptop stuff the ribbon cables are OK to work with, just pop up the retainer and they slide out. If you are not familiar just grab a 12 year old from an iphone factory, they will know how it works The case should now look like this:
    • Switching the console was tricky. First there were 6 screws to remove, and also the little adapter loom and its screws had to come out. Also don't forget to remove the 2 screws holding the central locking receiver. Then there are 4 clips on either side....these were very tight in this case and needed careful persuading with a long flat screw driver....some force required but not enough to break them...this was probably the fiddliest part of the whole job. In my case I needed both the wiring loom and the central locking receiver module to swap across to the new one. That was it for the console, so "assembly is the reverse of disassembly"
