Thanks for the responses.

1.There never was a fj20 that had a single cam head.

2. I already own a fj20e non turbo motor, I chose that over a SR because the non turbo fj's are really hard rev'ers, and i'd put money on one lasting longer than a Sr20de.

3. I've got a S12 inlet manifold with the shorter runners so that would help slightly with clearance of clutch master + brake master.

4. Wouldnt be to worried about gbox bolt clearances, as i've found that its usually easy to pull the whole motor / box out if anything needs changing (clutch etc).

I've already had a look at the 1200 feature cars on fj20.com, but none really specify whats involved in regards to the conversion itself.

Thanks for the input

Cheers

Martin
