Has anyone tried to convert a B14,4 To a b20f ? And what is there To know about a conversion like this ?

You will need all the parts as per converting to B172 so sump, engine mounts, alternator and brackets, starter motor, Bellhousing, clutch cable and throttle cable. You can then use the B20F engine.

The only other problem is that the B172 exhaust does not flow well enough for the increased capacity. The B18U exhaust manifold can be used in combination with the B172 inlet and carb. The other option is to convert to fuel injection system the B20F system and then keep the B20F exhaust manifold and use a early 400 series inlet manifold like this one




this is my old B20F converted 340 running on LPG only with a bodge inlet manifold.



And here with the early fuel injection manifold and B18U exhaust

what is causing problems with using the stock manifold and fuel injection ?? The donor car i got is a 464 from -94.

The air intake would be in the heater box with the standard B20F inlet manifold. The other option would be to cut the manifold and move the throttle housing to the other side so that it faces forwards.

I see ur point there. hmm something 2 think about. how to solwe that little issue

is there something more i can use from the donor car 2 my 340 -85 btw. power steering ?? Brakes ??

The engine and wheels are about all that are of any use.
