How did they do it?? Just heat them up and increase the pitch of the spring?? Does it feel the same to drive with? Just as comfortable?

Spend the weekend reading the build threads on here and Toymods... Its the fastest way to get an education in modifying Toyotas. hmm... 63 pages, starting at this link- http://www.rollaclub.com/board/forum/54-rollaclub-rides/page__prune_day__100__sort_by__Z-A__sort_key__last_post__topicfilter__all

What carb are you chasing to go with this setup?? Can you find a 32/36 Weber downdraught, or even better a single DCOE Weber?? That will make a big difference once you have the exhaust and cam in.

Pick the motor, gearbox and diff to use, then worry about suspension I'd say. Use a motor that fits a good close-ratio box and one you are familiar with (and can access parts easily after blow-ups!) I'd start with a good gearbox and grab whatever motor fits. Check 2nd and 3rd ratios and find what has the closest. In the end, that will determine what cams you run and how fast you go. Currently we are using a W53 or similar, can't remember exactly which it is, but it has the highest 2nd of all the Toyota W boxes. The best upgrade for us is an Altezza 6speed, unless we go up another couple of thousand dollars for something that is a factory close-ratio box. Take a look at the Steerfast Corolla build and aim for that!. http://www.rollaclub.com/board/topic/64392-steerfast-rally-ke30-2-door/

I don't think they are the same height. I thought the 5K was the same as a 4K, which is different to the 3K. Someone will now for sure. Ah, no- Wiki says- Now you might not get the rocker geometry working. Your 5K is running hydrasulic tappets and the 3K will be solid. The setup is quite different. The 5K head would ahve to be used for compression ratio. The 4K can be bored to 5K size if the walls are OK, but there might not be anything left of your 3K by then. I don't think its going to work at all.

You reckon it will still rev OK with a stroker kit?? I don't suppose it matters unless you're on the track at 7500rpm all the time.

Love it! I want a driveway like that! Love the aircon on the dash top too!

Oh no, you're dead right with that example, that's all shock work. I'm thinking of 75-100mm deep subsidences in the road surface, the 'potholes with slopes' that trucks leave, enough for the suspension to relax down into. When you hit the far side of it a stiff spring will push the body up harder than one of half the rate. ..and above that, a stiff shock will resist the strut compressing enough to give you a jolt. The whole movement in manufacturing has been to soften springs, stiffen sway bars and make the shocks work harder over the last 30years. Modern cars combine handling with comfort in a way old cars can never match.

...wait 'til you see my plans for a Woolshed Spec dry-sump system!.... :ninja:

Within the usual limits I'd agree. If you have a constant ride height between two springs but one is twice as stiff, the car will only go down half as far on a bump using the stiff ones. So that bump will feel more noticeable as the accelration is twice as much over half the distance travelled. But generally springs set the ride height and shocks set the ride comfort. I do know you can see some horrible cars bouncing down the road on rockhard springs while the V8Supercars look amazingly pliant considering how low they are. That 130mm of bump travel is pretty good, you must have had that well sorted.

Hey- you're not meant to have time to get on Rollaclub! Get back to work! Propshaft balance isn't 100%. There's a resonance starts around 50kph to 60kph, not really a noise, just a vibration in air pressure, and it seems to vanish or dissappear into the general noise by 80kph. Some vibration in the outside mirror at higher speeds too, but overall its not much. I wondered if it was part of the motor working harder to haul the tall diff, but I'll chat to the driveshaft man about it. I'm pretty sure the speedo under-reads, it was 5% over with the 4.3 diff, and we've changed that by 10%, so 95 on the speedo is probably 100kph now. I'll check it over the 5Km odo check on the way up next week.

The problem is that Aussie roads are quite 3rd-world, not nice smooth tarmac like V8Supercar tracks.. at least that's what I've found. Maybe living East of the Sandstone Curtain is different. You need suspension travel to drive up the backbone of the Great Dividing Range, and there's no fun in driving along the flat coastline.

That IS a surprise! Did you fit the supercharger yourself?? Is the sound stunning?? A banshee howl as it comes on boost?? The only one I've driven was on an electric clutch so it only kicked in when you booted the throttle. Wonderful to drive!

Cheers!- I assume they look like this, one end flattened and one end open. Usually the flat end (the top) closes right up and maybe touches the body mount 15 or 20mm past the spring end, and the open (diff) end might touch 1/3 of a turn, then instead of 7coils working we have about 5.5 active coils when loaded. You can see where they touch by just looking at the dirt marks in the coils. Using Pontiac Racing's rate calculator here- http://www.pontiacracing.net/js_coil_spring_rate.htm We can put in 5.5 active coils, wire diameter 10mm, OD of spring 115mm, press enter and get a rate of 87lb/in, or 1.55kg/mm. So they are quite soft springs and I am definately going to hunt a pair down! The RA40 had a kerb weight of 1000kg when new, we gutted it completely then put in a cge, so I reckon the front weighs 600kg and the back 400kg. The diff weighs 70kg, the wheels 30kg and the Bilsteins have a gas pressure of 40kg each. Subtract that from the 400kg and the springs are holding up 110kg each. They should compress from 320mm down to 150mm. 70mm of that is wire (7coils at 10mm) so we get 80mm of travel in the rear suspension that the shocks & bump stops have to control. That's not bad, a little less than we have, but worth trying to get more squat under acceleration. Thanks for that!

haha! It may look cool, but having chased this one down some winding roads, don't expect handling or ride comfort from cars like that-

Then check the compressions and see if one cylinder is down. That would be a burnt valve. All cyls low would be old rings. Have you checked the points with a dwell meter and checked the timing?? Have you checked the leads with a multmeter?? Any of those components could give low-speed misfires. Did you check-tighten the manifold nuts & spray for inlet leaks??

$180 is good- I think I paid $1400 for the Altezza's.... back in the dayz when I wuz rich! The adjustability of Konis is what makes them so useful, and the fact they can be stripped and re-valved makes them great for racing.

hmm... they look strange. Too much chin.

That is true, but Konis are serious shocks at a serious price. On the Altezza you can get the Konis grooved for several perch positions, so you can alter the ride height as well as the usual stiffness adjustments they have, but without coilovers that is not an option for the KE70. You can also change the valving on the stock wet shock in the front strut, that's not hard to do and you can build whatever shock rates you want. However if you are into rallying or khanacross then having the gas function will be more use.

Nah- the Govt doesn't pick up the rubbish now, a private contractor does. In typical Govt fashion they demand the money off us, pay a handful of bureaucrats to sit on their bums and pass the rest to a private contracor to actually do the work. The private sector would solve the infrastructure problems, the free market always finds the way. AND monopolies are usually the result of big companies pushing Govts to grant them special status like import restrictions and startup barriers. Without the heavy hand of Govt the competition would be stronger, so prices lower. If the Govt stopped at the law that said "you can't force another citizen to do something" then the whole place would grow faster. That is all the umpire does, not write so many rules that no one person can every know them all in his lifetime. Most of those 3rd-world places have a corrupt ruling class propped up by some Western country while the country gets ripped off for any resources. They mainly suffer from a lack of private ownership of land, the great downfall of tribalism. Without private ownership you have no captital and no way to borrow money to develop anything. We need to move into the next stage of civilisatiuon, where the rest of the power is spread downwards to the people, not just a vote once in a while.. ....and well well, suddenly we DON'T get any tax relief as promised, but we DO get to keep paying the carbon tax! What a surprise! Just another grab at private people's money by a Govt....

Often the rules only apply to cars, not vans, utes, trucks, SUVs etc. That's why there has been such growth in those markets as manfacturers tried to dodge regulations over the last 20years. Can we squeeze on some better-looking plastic ones off the FWDs that followed us??

Ah- why do we need a Govt... well, to hold you up and steal your money, then buy themselves power and jobs for mates with it of course! The parasites in South Aussie were sold a pup when deperate for water in the last drought, and raided the cash drawer for a desalination plant. Naturally they asked the rest of Aussie to pay for it through Canberra, who said 'no, its just a small local bit of hardware, do it yourself'. So SA doubles the size of it to something completely not needed, then goes back to Canberra, and now that there are elections coming up Canberra says "fine, look how wonderful we are, vote for us!' The extra kick in the guts for the taxpayer comes when the plant has to use heavily subsidised green energy, so not only do we get screwed to build these useless wind farms, we get screwed again to pay extra for the power to run the water plant. Water bills going from $300 to $900 !! All this would be typcally corrupt and ironically laughable, but to top it off the plant is not needed and will be mothballed!! Just like the motorway bridges that led to nowhere in the 1970s! Expensive election bribes that never added a dollar to anyone's wealth except those cronys involved in building them. Auckland had them, Cape Town had them, and I'm sure they were here too. Now, if you've ever bought a car that has been sitting in a shed for years you will understand what "mothballed" really means... it means ruined and useless, and needing massive rebuilds before ever being used in the future. AND of course technology races ahead while the car sits there and it is completely out-of-date and not worth using when you go to get it. The only value of the desalination plant will be as a monument to Govt stupidity. If the private sector won't tackle it, then it will never work efficiently. http://www.theaustralian.com.au/news/federal-auditor-general-blasts-decision-to-double-size-of-adelaides-desalination-plant/story-e6frg6n6-1226636757321 http://www.adelaidenow.com.au/news/south-australia/water-customers-pay-for-mothballed-desalination-plants-costly-green-electricity-deal/story-e6frea83-1226537887265

Go for it- I asked Ironkin if it should be anywhere in particular, I've managed to spread writeups all over the place and they are only linked through the build thread. Half of them, including the RA60 diff swap, are in KE70.com ..and the really really good news is that today I found out one slave cylinder is leaking, so I'll have them all apart again tomorrow! :bash:

$2500-$3000. no-one is going to appreciate the new interior, the new paint job will make it look nice, but its still an old old car with a 1300cc pushrod motor. You know someone will buy it, paint it matt black with a rattle-can and gut out the inside while they chop the springs to nothing... Keep it and enjoy it.

Ah- So it was unused but definately not superb when you got it! Nice work.
