true- too retarded will drop the idle speed and stall it... Maybe a general tuneup AXTX.

Strip an clean everything would be best. It may not need a kit if its just a random bit of dirt that's got in there, but it means your fuel filter is suspect. ..or just pull out the idle jet, look for dirt in it and blow through it.

Dirt in the idle jet, or an air leak that makes in too lean at idle.

RB20, tell me about the Jaycar unit- Did it work OK? What sensor did you use with it? Did it need anything else apart from wideband 4wire?? probe and that Jaycar module? Was the AEM unit worth twice the price??

OK, I'm looking at making an incar mixture guage for tuning with the twin SUs- I want to be able to optimise the needle shape without spending a fortune at the local dyno shop having him read the mixtures for me every time. So I assume I can build a Jaycar LED display for $20, which hooks up to an oxygen sensor and flashes different coloured LEDs depending on the A/F ratio. Now, can I hit the wreckers and buy a pair of oxygen sensors from two cars down there?? ..and will narrow-band do it or do I need to go to wideband? It will be the sort of thing that gets used for a month until I'm happy with the carbs and then thrown under the stairs, so if anyone wants to borrow it after that it would be OK. has anyone built one??

They will regrind yours, I don't think anyone has access to blanks anymore. I pulled the motor out, lifted the head off and took the crank out, but left the pistons in. I had the crank cleaned & fitted new bearings, (they were a bit worn from a poor oil filter years ago) & took the valves out and had them and the seats machined, and had the head skimmed 15thou. The cam I sent off to Crow and had it ground, and when I put it back together I fitted twin SUs and extractors. It took a while but all went together nicely in the end. I didn't touch pistons/rings or water pump or cam chain/tensioners, just cleaned everything up. The flywheel I'd had skimmed a year back with a new clutch so I didn't touch the clutch setup. oh- and I fitted the spacer under the oil pump spring! :P

Isn't that an east/west engine?? So you would have the hassles of turning it 90deg? How about the 3SGE from an Altezza, already north/south and will almost drop straight in.... get the whole engine & 6speed as a package.

lol! Put this straight into the Wiki!! This is the sort of info that we need for real work!! Some of these things I've never heard of, and they are so clever!

I've got a brand-new race harness that's never been used... I never got around to putting it in the rally car before I sold that, and just never advertised it. I'm sure there are lots of rally/race cars get written off and generate 2nd-hand gear. Grab some 2nd-hand tyres that are still usable. There's a big market in rally tyres where top guys have done two stages then they can afford to put fresh ones on, so I assume racing is similar. If not, there are some great sports road tyres that will do weekend warrior work, like the R888 Toyos http://www.thelotuscentreonline.co.uk/ecomms/item633.htm ..and you're right- you become a better driver learning in an underpowered car rather than an overpowered one!

yep- same as a head gasket job really. You do the strip and clean, a machine shop takes care of the head/valves, then you do the reassembly. You'll need a set of spanners, some WD40, a torque wrench and lots of patience, but you will learn a lot! Go check the tappet gaps and see how they are. I'd lean towards a head gasket rather than a bent valve.

haha! you're my sort of mechanic!! An imperial socket might just jam on there... How about a small plumber's wrench, the sort that lock up on pipes when you put force on them. I have one 6" long, but they probably come smaller. ..or smaller vicegrips? Kimby I was wondering how that project was going.. You should invite anyone on here to come around for a beer and give a hand, there is a lot of expertise in Sydney. I'm a bit far away unfortunately.

Brakes and handling!! Especially if you can swap 2nd-hand bits in from bigger cars... Nothing better than outbraking some big, powerful car that just overtook you down the straight and sliding down the inside into the corner! Unfortunately finish lines are on a straight...!! Bloody 911 Porsche pulled out of a country driveway in front of my Datsun 1200 (well, 1500!) one day, on a downhill twiisty bit. I blasted past him into the next corner with all the speed I already had and it really upset the dude! He had it all over me a few hundred metres further on when we had to go uphill, but it was fun at the time!

What year is your car? You'll need someone to measure the same car over here. Do they get both models over there? Flat nose and slanty? I know there are quite a few different versions of KE70 nose furniture around the world. Mine's a slanty so I'm of no help I'm afraid.

Ok, so you have swapped the lead over, and the plug over and the miss stayed on number 2? Check the tappet gaps and if you have a compression guage do a comp test. A bent valve or bent pushrod will show as a bigger tappet gap, and a burnt valve will show as low compression in that cyl. Is the misfire constant from startup to warmup?? No problems with water vanishing or condensation under the oil cap?? Bubbles in the radiator when cold?? The dyno run may have blown the head gasket slightly between 2 and 3 and you have water getting into #2, which will make the plug misfire when cold or until you change the plug.

Ah- nice, Raven. That's the sort of info that is always handy to have stuck in a reference somewhere... I had mine apart apart a few days back as I chased a wiring problem, but I only took the electrical side of it off. Turned out one fusible link had broken inside its insulation down on the starter motor, so it wasn't supplying the ignition system all the time.

That's a damm nice car! Don't f@$k it up with matt black paint or ripping out the interior or anything stupid. You'd need to decide what you want out of the car first... daily driver, weekend warrior, serious grunt but hopeless in traffic... That will set the cam you get and the compression. Plenty on here about it, 280deg cam and 20thou off the head does most people. ...and yeah, that's a big exhaust! What's the muffler setup and the noise like? Now someone was selling a 'new' electronic dizzy on here a week or so back, a KP61 I think it was. Same dizzy anyway, one of the site sponsors. If not, you can get reco ones from the USA for $100.

Tappet gap will tell you... big gap for bent valve or pushrod. But if it ran fine with a new plug for a while it won't be either of those. You'd have more chance of a broken oil ring shitting up that particular cylinder. The lead shouldn't give you a shock either, so they aren't much good. I occasionally look at night, especially a foggy or wet night and check for green sparks jumping around the leads in the dark. If you're lucky, the water destroyed the lead's insulation on number 2, a new plug had lower resistance so it fired for a while, but now that plug is harder to work so the lead can't hack it anymore. Swap leads and see if the miss moves. It may sort itself out when it dries out completely.

Muck around with rental houses most the time, although currently I'm extending this pole verandah I rebuilt for a mate. I enjoy working on houses, having been a scientist for my early years and just a self-taught builder.

Dead right, but don't leave town! I tool around in 4th all day in the 50-60kph zones, but try and cruise at 100k and it revs its ring off in 4th. The 5speed is just a 4spd with an extra overdrive gear, the other 4 are the same ratios.

Come up to Orange in the weekend, there are several in the local wreckers. I can go and make sure they have axles if you like.

Have you got an oil light as well? Does it come on at idle? I think the oil light switch works at about 6psi, but you might be looking at slight differences between guages for that. Are the tappets noisy Evan? I took mine back to 14thou and they are quieter, but it depends how you set them... cheers Keith

A crew! Hardest thing to organise and keep together for a year or two, just like a rock band! You're the lead singer and will get famous, but behind you will be the guys who do all the work for no thanks. You'll need a hard-working serious guy as navigator/manager and a couple of dependable guys to run a service wagon and hopefully be able to fix what you break! and lots of dedication and money! oh yeah.. and the licence.. cabbage needs one too!

That's even high at idle from what I'd expect. I'd expect a range of 60psi cold and driving down to 10psi at hot idle. Running hot at 40psi is fine.

We had an underbench filter unit at the last house I owned, so there was no chlorine in the water between the filter and the tap. I never used it, but my son did and one day we were doing the dishes and chatting about it, so I pulled the bit of slime from just inside the tap out, and he nearly choked! Didn't worry me, I'm a microbiologist and I knew what happens when you take the chlorine out of the water, bit it did look pretty gross. Funny, he never drank it after that....
