Rebuilding a 12 valve Dash motor

[WANTSOM]

Be careful about where you place the injectors with the DASH ports as the spray pattern has to cover 2 distinct ports.

510's will be fine. You can buy fuel rail by the length and cut it to suit. Then make up your own lines and regulator (I use an aftermarket Sard item) and a Falcon XF throttle body - 65 mm

The combo makes about 180kw atw with a TC06 on 16lb boost

so what kind of power would the same set up on a normal 4g63 make in comparison to the dash?

[WANTSOM]

about 150-165 give or take

Your engine looks so sweet....but as a reference to other people, would you say this conversion is worth it? I actually love the dash power and mine was excellent, but most of the guys here struggle keeping their basic std cars going.
The balance shafts need to be moved as they chop out the bearings when given a hard time. Not just in the 63 but all the others too!

I thought a Dash would have less potential than a 4g63? Wouldn't the single exhuast valve hold it back?

IMHO and having gone through a fair amount of grief and expense doing this I would have been better off going down the VR4 road from the get go. Yes it would have cost slightly more but the amount of dickin 'round I did would have reaped a much higher output and been able to source a lot more "compatible" parts for about the same effort. The reason i did it was a) I had the DASH head already, b) the original T/Body ended up being rooted and the decision was made to go MPI as I could get a manifold for a semi reasonable price as a custom jobbie.

A better (read cheaper and easier) option is to play with single cam 4G63 -do a little head porting, a Sonata manifold, XF t/b, decent cooler and a freer flowing exhaust with really nice well matched TD05 and you have yourself a ball breaker street car.

I aint sorry I did the DASH MPI setup but man was it a pain in the arse along the way. :o

Its generally not a good idea to rotate the head on the tbi. This will cause fuel distribution problems I have heard as the design was rotated that way initially to make sure that the air and fuel would hit the cylinders as evenly as possible when firing from a central point. Rotate it around and you will screw this up.
