What about the spigot bearing? A very good question indeed! No spigot would lead to a lot of vibration as the g'box input shaft hammered the end of the crankshaft to bits! Even if you fitted a spigot bearing it could be out of balance as that flywheel was not on that crank before. Maybe its just a bad combination... that shouldn't be much of a vibration tho' You didn't take the box out did you?? Fitting the driveshaft in a different orientation can upset the balance too. ..and I assume the clutch is slipping if it takes off slowly when you think it should take off fast. Does the cable pressure come right off the thrust brg? You should be able to pull the outer cable back 5 to 10mm away from the gearbox arm before the thrust bearing hits the pressure plate. Pop the box out and go over it all carefully. Mark the driveshaft so it goes back on the diff in the same place.

Sounds odd to me... is there oil in the diff?? I assume your mechanic checked that first.. Ok, when you turn a corner, the spider gears rotate, any corner at all. They rotate faster as you turn tighter. So from that point of view they should make the same noise left or right. However, the motor does drive one wheel more than the other, driver's side) so it may be that the spider gears are making a noise on "drive only", when you're turning left, and not on "anti-drive" when you're turning right. I've only run across wear-mark noises from the crown and pinion, and bearing noises. These vary with acceleration or cruise & speed. so they might get noisier as you go faster, or noisy speeding up compared to slowing down... but not turning corners. No chance that the backing plate is scouring the drum under load or some odd thing inside the brakes? I checked up rebuilding a noisy diff but it was going to cost too much, up around a grand as it had to be sent out of town. In the end we kept the quiet auto diff. The 5speed is a vital addition, every 4K should've had one!

Really hot suggests shorting staight to earth.. If you take the negative lead off the coil then touch it back on, does it spark?? If it does that means the coil is going to earth somewhere. Then make sure the points are open and do the same again. If it still sparks on that coil spade with the points open there is a short somewhere that shouldn't be.

Second that! Pick the top speed you want to do and work backards to the ratio that will do it at peak useable revs. 4.1 to 4.5 is much more likely. We rallied with 4.6, some guys using 5.1.

Yeah I wondered about that Jono. Bit hard without photos! Anyway- how did it turn out Chillin??

Well, it has an 'emissions ECU' that needs the O2 sensor. http://www.toyotanation.com/forum/archive/index.php/t-327656.html here's a wiring diagram for it- http://home.insightbb.com/~jmengel4/wiring2.2.jpg That's from http://home.insightbb.com/~jmengel4/auto.html#enginespecs

Are you going to bolt the bracket onto the clutch pedal so it can be moved if needed?? That means it is a "U" shape, not an "L". It all sounds good, but I know working in that cramped space upside down at wierd angles is direct line to swearing and apoplexy!! I can see the cutout in the black insulation beside the clutch pedal on mine and the ridiculous shape of the pedal shaft. Any civilised manufacturer would have mounted the steering column between the clutch and brake pedals, not wound the clutch pedal shaft around the steering! It will have some strange leverages. Anyway- theory sounds fine- Good luck with it.

sooo.... that is running the dizzy as usual, but with the HT lead earthing out?? I usually put a spare spark plug in the main coil HT lead and lay it on something metal. You need the points working properly for the coil to spark.

Electronic dizzy or points?? Is there spark when you put a screwdriver in the points with the "ignition" on and wiggle it? or take off the dizzy cap and turn it over and watch the points- you should see a spark across them every now and then. No spark=problem at coil end or broken wire or condensor shot.

So its still on carbs, not fuel injection? What did the O2 sensor do with carbs? I haven't come across an ECU with carbs but I suppose some of the realy tricky emission valves could be computer controlled. Have you tried these guys? http://www.3tcgarage.com/

270deg Crow cam, twin inch & 1/4 SUs, 4-1 extractors.... more or less stock... :laff: The dude did a great job with the exhaust, I told him I wanted the 2" stepped down to 1 & 3/4 after the resonator, and he said he picked a muffler that had an old-school MG-B sound to it, so it gets crackly if I boot it hard. http://www.rollaclub.com/board/topic/42407-the-girls-ke70/page__st__15

So, are you converting from the USA's carbs to Japanese fuel injection shooter? Did you get all the bits you needed? That's the bit that worries me!

The answer to- surely is..... "Why" is the real question... there is enough oil to run the place without everyone rushing off to grow corn and turn it into fuel. Within 20years solar will be far more efficient than it is, nuclear reactors will be being built again and if we are really lucky there will be a breakthough in cold fusion. So why the hell would they want us to use so much of a second-rate fuel?? Keeping the good stuff for the military are they??

Are EFi swaps really like that?? I figure that they needs all sorts of sensors and computers and wiring that won't be in an older car so you spend months hunting down odd problems that may not have occurred in the original EFi car. Seems that way with the Altezzas, but they're trying to keep the climate control running and the other peripherals and end up blending two computers. I wouldn't really know, having never fitted EFi. Any ideas from you guys that have done it??

Well, the white whale needs 4tyres, 2 rear shocks and a mighty engine clean until oil leaks are un-noticeable, then another rego inspection. I don't know if your rear shocks go up through the body with a vertical pin like any decently designed shock would, but the wagon's are held in a little cupboard by a horizontal bolt right beside the spring. What a dog to get out!! No room for a socket, 1/8 turn at a time, only one hand's room... If you're planning a shock change, allow for lots of time and swearing! Skidz, when you're under the bonnet could you take the oil cap off and let me know if that changes the idle speed?? Pulling the rubber tube off the tappet cover does, it nearly dies unless you block it with your hand, so I thought 'well there must be a valve in the cover that stops that'. But when I put the tube back on and took the oil cap off it changed it too, which is quite odd. Actually, now I think about it there is no PCV that I could see, so maybe it keeps the whole engine under vacuum... Which means my oil leaks are fighting against vacuum to get out! It does blow enough oil vapour to fill the plasic airway that contains the airflow sensor with oil!! :laff:

This was taken in the boot- So I reversed up the drive, then out into the toad, then drove through a few T-junctions we have close to home. http://img715.imageshack.us/my.php?image=6yjj.mp4 and this was incar, just driving down the road. Now I realsie there is a lot more background noise inside the car than exhaust noise! http://img156.imageshack.us/img156/4098/a2h.mp4

If it does run well we would like to know what venturis are in there and what jets you are using. Somewhere along the way we will get a library of carb jetting set up so people can buy carbs off other cars and easily jet them to 4Ks.

Do you want to drive it or are you happy for it to languish in the garage for a few years in pieces? Like my Datsun 1600 that was last registered in 2001 !! Do the manual conversion and the Holley, & drive it for the rest of the year while you get the 4AGE fully sorted and ready to drop in. When you have holidays you hit the 4AGE conversion.

Calorific value must be lower as it already has an oxygen taking up the place of a carbon or hydrogen, so yes, you need more of it to get the same power. The guys who run on methanol use giant jets to feed enough fuel in. here- Wiki.. Ethanol is particularly pathetic. Fuel↓ kJ/g↓ Hydrogen 141.9 Gasoline 47.0 Diesel 45.0 Ethanol 29.7 Propane 49.9 Butane 49.2

I use the E10 becasue its 95octane and as cheap as everyone else's 91. It doesn't seem to have any ill effects. I'd worry about E15 though, which will be the next step. That's too much alcohol and water liabilities. Not to mention what it does to a breath test.. adds an alcohol background that fails you easier! :laff: Of course you do have Brent crude at $107/barrel tonight when it was $75 a short time ago, plus Libya's problems of Govt PLUS the fact that last month world demand exceeded supply for the first time in years, so you can expect to see petrol rocketing up and less and less real oil in it! I thought Aussie's alcohol came from fermenting sugar cane waste, a much better idea than using corn. Without the poor fking American taxpayer subsidising the hell out of their corn industry for 50years this would never have got off the ground.

Philbey do you use a head gasket sealant when you're assembling high-comp engines?? Hylomar or Permatex or something?

Nah- repair it. What broke? Almost anything can be fixed...

Wrap the headers Andy. Atrocious piece of design putting the starter and alty under the exhaust, but you can keep them cooler.

Even 2" is bigger than you need. Get the extractors, which end in a 2" pipe, run it 2" to a 2" resonator, the longest you can buy, then run inch & 3/4 to the back with a tri-chamber muffler not a straight-through. The resonator takes out the harsh crackle and stops it backfiring. Sounds great, a little louder that sotck, breathes well and never attracts the cops. Maybe we should start posting up some sound tracks!

Weber, cam and quiet exhaust. & a 5speed! The Weber looks enough like the stock carb, the cam doesn't want to be more than 270deg, and if you keep the exhaust quiet no-one will notice it. Best way to fail... matt black, or more than one colour, chopped springs, wide wheels, no bumpers, 2" exhaust and cannon, no air filter for wild induction noise... and drive it like you stole it! :laff:
