Turbos shot on my ‘70 335. While I have it apart I’m going to upgrade the exhaust manifold also. So best aftermarket turbo/manifold setup? Couple mm bigger on the turbos A-OK

If you can find someone that still stocks the Schwitzer (BorgWarner) 4LHR Turbo then p/n 197916 works really well on 335's with no Jake Brake mods needed or for a slightly larger turbine A/R use the 196390.
If you can't find those turbo's then a BorgWarner 167050 BHT3B single entry will do the job, again no Jake mods needed.

If you don't have a Jacobs Brake then use p/n 196441 HT3B with divided exhaust .

Hope that all helps,
