what the hell is that dash cyl head?, i've never seen one or even heard of one before, looks awesome!
looks like it had vtec or something, does it work that way?

p.s.
i'll email you the parts list once i sorted out all thats missing, and some pics to figure out, thanks

DASH stands for Dual Action Super Head - it works by increasing the intake charge velocity at lower rpms by opening only the one smaller inlet valve, then at 2500rpm and above the larger inlet valve opens up as well. I guess it is a very primitive form of variable valve control, but instead of controlling valve lift and duration it just controls the number of valves open, giving you the benefits of a torquey 2-valve motor at low rpms but the higher flow of a multi-valve engine at high rpms. The DASH motor runs 12-14psi boost from the factory and has a redline of 7000rpm, fairly impressive for a SOHC motor.

engine's back in the hole! Gave the engine bay a bit of a clean up before hand too.










Unfortunately hit a bit of a snag, because I don't have a wiring loom for the DASH ECU and injection unit that I have, I opted to use the original injection unit - it bolted to the DASH inlet manifold fine but it overhangs a little bit and there happen to be vacuum passages exposed where it overhangs, so it's probably going to run like ass. Also the existing intercooler piping doesn't quite fit over the top of the rocker cover as the DASH injection unit is raised up because the DASH head is taller. Also as it's a FWD inlet manifold the thermostat housing is positioned in an awkward spot and all the coolant lines running off it are just pointing in the wrong direction so need to mock up some other piping to make it work.

I may try making up a wiring loom for the DASH ECU if I could find the correct plugs which go into the ECU, but chances are the injectors will leak as they've been sitting for so long and the DASH injectors are known for leaking anyway.

beautiful motor!

ps

Interesting info on the DASH head - were DASH-equipped cars ever sold here in the States?

Nope, they were a Japanese market engine only. We only got them via the used imports that we got from Japan in the 90s.

How rare are they? What'd they come in?

came in 84-86 A183A and A184A Starion GSR-V (RWD orientation, badged as Sirius DASH) and 84-87 E15A Galant Super Touring and Eterna VR (FWD orientation, badged as both Sirius DASH and Cyclone DASH).

Thanks for the info. I want one of these so badly.

there's a bit of info about the DASH Starions on this page here, will need to be run through a translator if you don't speak Japanese.

Phil I was gonna ask why your rocker cover says CYCLONE instead of SIRIUS, but you answered the question in your last post
