Technical T-Jet Exhaust Manifolds, what ones fit?

[TurboP]

As we are seeing a lot of the old Tjet 120/150 manifolds cracking and reading a lot about the later manifolds being reinforced and with the flange cut outs to prevent cracking I’m looking to get one.

However there is so many different numbers I have seen, ones to fit the Garrett and others for IHI turbos. Want to know if these other numbers bolt straight on and turbo is positioned correctly or is there a slight difference?

Numbers I have found are:

55217497
55213777
55221553
55282011
55236503

I'd cut the existing (old style) manifold as is the (improved?) one, just to kinda release temperature stress as it seems to have fixed the crakings issue ...

BRs, Bernie.
