I guess I'll be the first one to say it.
Search.
I am not being mean or anything, just do some research.
R32- Most 89-92s had bad oil pump drive collars, resulting in faulty oil pump, resulting in engine failure. Ceramic wheel turbos. Ran about 9-10 pounds boost. All engines came HICAS equipped.
R33- Physically about the same as the R32. Oil pump drive collar problem fixed. Ceramic wheel turbos. Different wiring harness near FPR, different oil fill cap. Ran about 10-11 pounds of boost stock. Don't know if they had HICAS or not.
R34- The popular Red valve cover came into play. Steel wheel ball bearing turbos replaced older ceramic wheel turbos. Ran about 1.0 bar of boost (14ish psi). And many other changes.
