Sohc astina to gtx fwd
 

Hey I have a 92 astina 1.6 sohc. I'm looking at doing the bpt conversion to it. I'll most likely be purchasing a sedan gtx, whole car that has been written off. (T-bone damage)

My question is- how straight forward is it? I'd be looking to do it over a 4 day weekend as I'd need the car to get to work on the Tuesday.
I've done engine swaps before, rebuilt engines all that sort of thing. But never done a sohc to doc conversion.
Is it likely to be a 3-4 day job?

Thanks for any input!
