fuel Posted October 15, 2006 Share Posted October 15, 2006 Hey Eliot yeah the extra valves are controlled by the oil solenoid. It's basically like a primitive MIVEC/VTEC. I would say you can use an aftermarket computer to control the extra valves just like MIVEC/VTEC. And Dicey, you could use the non turbo block as long as you use the DASH internals (such as a crank, cradle, pistons, rods, oil pump cover, sump etc). I'm not entirely sure if the turbo block has oil squirters in the block itself. Quote Link to comment Share on other sites More sharing options...
Dicey Posted October 15, 2006 Author Share Posted October 15, 2006 yea dont think the non turb block would be the best option know any 1 wiv and turb block 4 sale lol maybe free?? Quote Link to comment Share on other sites More sharing options...

Blueex Posted October 23, 2006 Share Posted October 23, 2006 Is the 12v dash block the same as vr4? Quote Link to comment Share on other sites More sharing options...
lowlancer Posted October 24, 2006 Share Posted October 24, 2006 Yupp, sure is, bar it's wide vs VR4 which is narrow Found that I can just leave the oil control valve disconnected and have the extra valves working non stop. They DON'T work when 12V is applied to them... Quote Link to comment Share on other sites More sharing options...
Blueex Posted October 24, 2006 Share Posted October 24, 2006 But what about 12v fwd narrow? Quote Link to comment Share on other sites More sharing options...
fuel Posted October 24, 2006 Share Posted October 24, 2006 The actual DASH core block (and other SOHC turbo 4G63s) is the same as the VR-4, but there are lots of differences like the crankshaft, the oil pump assembly and cover, water pump etc. The rods and pistons of the DASH are the same as a VR-4, but the crankshaft is different, along with the front oil cover on the engine and crank pulley itself.

Blueex Posted October 24, 2006 Share Posted October 24, 2006 Wicked, That means that i have more parts 4 my vr4 engine than i thought. Quote Link to comment Share on other sites More sharing options...

They DON'T work when 12V is applied to them... Microtecs have atleast one aux out that you could use for this. Would be super simple to hook up and program, just make it put out 12v from idle to 4 grand or so then drop off after that. Will probably add abit of torque and help wind up a little easier. Might aswell aye..? Quote Link to comment Share on other sites More sharing options...
Dicey Posted October 24, 2006 Author Share Posted October 24, 2006 hey just wondering wat the dash motor sounds like when the secondary valves open?coz i don't wat 2 sound like sum gay honda shown off. plus i was thinking of runing a td05 turb would it be 2 big for the dash 2 handle?

fuel Posted October 24, 2006 Share Posted October 24, 2006 the valves open at 2500rpm so I doubt it will sound like a roaring vtec or anything. It's basically the same principle as the cyclone butterflies on the intake runners on a VR-4 engine. At low rpm the intake is restricted (set of valves shut on the DASH, half the runners blocked off on a VR-4) to promote turbulance and better atomisation of fuel at low rpm, and at higher rpm there is less restriction so there is more flow. Either system is results in more torque in the lower rev range. Quote Link to comment Share on other sites More sharing options...
