If you're lucky enough to have a 14B-T (or 15B-T), you may have noticed that many 14B-T specific parts are out of production. However, there is good news. The 14B-T was adapted into a series of marine engines by Yamaha, such as the ME370. These shares many (but not all) components with the Toyota/Daihatsu 14B-T. The part numbers get a Yamaha prefix and are differently spaced, but where the part is common to the Toyota engine. they are the same numbers.
You can find a part catalogue on the IMPEX website: Marine diesel parts YAMAHA (1993, 00EK) — IMPEX JAPAN - https://en.impex-jp.com/catalogs/marine-diesel/yamaha/me370/6tc-1993-metallic-marine-silver-mms-00ek-europe-general-999-26680.html
Here's what I got today:
Fuel injector nozzles. These are Denso DLLA150P621s (the originals for my 15B-T are -622 but these are long gone). The Toyota 14B-T used DLLA150P75s and are NLA from Toyota and Daihatsu. I have no idea what, if any, the difference is, but the Yamaha engine produced more power (165 HP vs. 140HP) and the Yamaha nozzles (which were also used in some Daihatsu engines) were much cheaper (about EUR 50) than Denso-branded DLLA150P75s (about AUD 200 - 260).
I also got the turbo exhaust manifold gasket, which is NLA from Toyota. It has 'T' stamped on it (like the turbo 14B pistons) but is the same thickness as the NA 14B gasket. The only difference I can see is that it has a different, sprayed-on surface finish on the manifold side of the gasket.
Not specific to the turbo engines, but I also got injector springs (NLA from Toyota)...
...and one of the rocker shaft supports, also NLA from Toyota and Daihatsu.
I ordered from IMPEX. Their prices are very low but they are quite extraordinarily slow. Still, I would recommend them as a source for these Yamaha parts which Amayama does not carry. Megazip also list the parts but are about twice the price.
Hope this helps a 14B-T owner, or a fellow 15B-T owner, if any are out there..
