Are the turbo downpipes for the T3 and k24 the same? Also, are they interchangeable between the mk1 and mk2 chassis?
im not sure whether the two are interchangable between turbo's.. But i would assume they would have to be car generation specific.. due to that they have to over come the same obstacles of the steering rack difference on the two.. but i could be wayyy off

Free bump anyhow.. lol
AFAIK the only thing required when changing between the two turbo's is the oil return line. i would also assume them to be interchangeable between mk1 & 2.
I think they might be different length mk1-mk2.Both the cast pipe and downpipe.MK2 k24 and T3 pipes are all the same.
