Re: Rear axle retaining nuts

Yup, yup. Thanks sham. Do you know why the factory nuts have that extended flange/lip? Clamping force and also related to 'hardness' of the fastener, ordinary flat washers cannot exert the same force as hardened steel washers. Toyota do stuff right, that's how they roll. Read this book for more inf...

Re: 5spd dogbox transmission T50 for Toyota, AE86 etc. models

I keep considering buying one of these gearboxes but each time I'm put off by the very tall 1st gear ratio. Whilst I realise that a lot of customers will be using the gearbox with different axles my car is an AE86 with a T series axle and final drive ratios lower than 4.778 are expensive, short live...

Self locking is achieved with controlled deformation of part of the thread.
Interestingly they may not be available in the USA

Re: Ignition timing problem

Ok I just read through the whole thread again, firstly turning the distributor clockwise retards the timing and putting the engine in diagnostic mode further retards the timing and that would explain why the engine dies when you put it into diagnostic mode. Once you get the engine idling, use your t...

Re: Ignition timing problem

When you say harder and harder to start can you describe what is happening ?
Does it turn over really slowly as if the battery is flat.. but it isn't ?
Or does it turn over at the same speed but refuse to fire ?

Just look at Jondees photo above ^^ and all will be revealed. The white 10°mark is where you need to be when in diagnostic mode, out of diagnostic mode it should go to the 15°mark or thereabouts.

Re: Ignition timing problem

I suggest that you try advancing the ignition timing. What you currently have is a spark that is happening somewhere around 0° but you need a spark that is happening at 16° before 0° (16°BTDC)

Re: Ignition timing problem

"The only thing that was missing verification was the little dimple on the camshafts.. it was not visible through the oil fill cap. " Don't overlook this important step, your timing could be 180° out.(After market cams generally don't have the notch) Turn over the engine by hand until the ...

Re: Ignition timing problem

Also make sure that the camshaft dimple notch thing is lined up when looking through the oil filler hole. See factory service manual.
I can't remember, maybe someone will, is the camshaft dimple lined up when the engine is on TDC compression ?

Re: Ignition timing problem

First you need to ensure that your distributor is installed correctly and not a tooth out. The way that I do this is to set the engine with cylinder number one piston at 10°btdc on the compression stroke (or where you want the spark to happen) remove the distributor cap and check that the rotor arm ...

Edited away my first response, it was a bit harsh ! When you say 'old engine' I guess you mean he is still using an old Ford engine ? Assuming his is 1600cc then it is nicely developed to produce the quoted numbers, especially torque. Relatively easy to match his hp but the torque in my opinion will...

Re: advice on cam timing?!

Ideally you would know how far you can adjust before the valves hit the pistons so with that in mind... Generally, once armed with the knowledge as above the cam timing would be adjusted whilst the engine is on a dyno. What would I do ? Advance the inlet first (cam timing wheel held still, turn the ...

Re: 20v smallport inlet

Very interesting re. flow figures and it looks like it might be worth the effort.
I wonder what the chances are of the inlet manifold studs lining up are ?
The turbo plenums are very nice but they look 'modified' as far as the scrutineers are concerned.
