Sorry but we need BS detectors, thats to stop many dreaming into the wrong direction. Ive misquoted figures in the past and accepted being wrong and duly apologised. Misquoting is fine but encouraging something that is a waste of time is not respectful and destructive to datsuns such as the rare K.
Critique is healthy to encourage constructive modifications and reduce wasting resources such as time, money and rare cars.

There are a number of late 2ltr light alloy engines available now and the SR is not in that category as discussed and surely will be asked by many noobs to come.

Those that love, respect this forum and datsuns should try to not slander incorrect advice.

As mentioned anything is possible with modifying cars
....but its least the case for logic and common sense.
