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 ...

Re: What's needed?

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.

Re: Weird Radiator Problem

Possibly nothing more serious than an air lock in the cooling system. Make sure that the radiator is filled with the heater on 'hot'. Pour some coolant in and then run the engine on idle when filling to the top.

Re: 4AGE 20V MANIFOLD GLOWING! HELP

At this point be very careful about putting the engine under load as the high idle suggests that the ecu initial timing is out, it is crucial that the ecu sees the same ignition timing as the engine is actually running. Refer to the ecu owners manual for help on how to set initial ignition timing.

Re: 4AGE 20V MANIFOLD GLOWING! HELP

To be honest I can't remember if the engine is at compression TDC when the cams are aligned.
Ignoring the cam / crank relationship for a minute it is possible by using the ecu to advance the ignition timing by say 10°as a test.

Re: 4AGE 20V MANIFOLD GLOWING! HELP

Ok so TDC happens twice in the cycle, once when the valves overlap, exhaust closing and inlet opening and the second time on the compression stroke. The compression stroke timing event is the one you are interested in for ignition timing. I'm not familiar with camshaft markings on the 20v engine so ...

Re: 4AGE 20V MANIFOLD GLOWING! HELP

Most likely retarded ignition timing.
Possibly a cam timing issue, too much overlap at TDC and some of the inlet charge is going straight into the exhaust. If the actual engine timing (not ignition timing) is correct have a look at VVT settings.

Re: Need suspension advice! Figuring out what springs would go with Tokico Illumina shocks

Damper length will dictate spring length to some degree. If your dampers are 'full length' then fitting a lowered spring will mean that the spring will come loose at full extension, maybe not too much of a problem. Another bigger issue will be that the damper is likely to bottom out and when this ha...
