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 |

In the early 90's I needed a replacement for the rusted out second muffler on my 76 car. NLA (no longer available). None of the usual Porsche mail order places had one. So, I bit the bullet and ordered a complete 74 2-liter style exhaust conversion kit from PB Tweeks. Remember them? It included two SS heat exchangers, copper sealing rings, 74 exhaust hanger, Bursch quiet exhaust, exhaust gaskets, and J-tubes. The kit price was about $1200, a shocking amount at the time, but now that might buy a single SS heat exchanger.
