I need to replace one of my heat exchangers on my 1975 1.8. Will earlier 1.8 or 2.0 heat exchangers fit? Thinking the earlier exhaust would improve performance. Are they compatible, improve performance and is it worth doing?
Thank you for the help! Cheers UPDATED |

Yes, as Brant says. But you need the full kit from the copper rings in the heads to the muffler. Given that the heat exchangers differ considerably from 1.7/1.8 to 2.0 you need the correct sided copper seals in the heads, the heat exchangers, the muffler hanger, the muffler & gaskets and probably the tin ducting under the heads. That is a full swap of the entire exhaust system.
