I have personally sat and drove a silvertop 20v dli on a TE27 before and i feel that it has big difference compare to the stock 20v. The VVT is engage by throttle respond.
In my oppinion that the advantages of the dli over the distributor system is in the ecu and the firring order of the coil.
The advantages of dli ecu is 2 of the injection will inject together at the same time compare to 1 injector injecting for the distributors. The injecting order for the distributor is 1,3,4,2 but as for the dli system will be 1&4, 2&3 injecting at the same time. Dli system duty cycle is much shorter, by the distributor finishes one round, the dli system will already have finish 2 rounds. The injectors are giving more fuel by using the dli ecu creating a better fueling efficiency.
The advantages of dli coil is that the twin coil has a longer firring sparks and much brighter sparks( Personally tested). Firring order of dli is also much shorter, 1&4, 2&3. Burning away all the extra gases which is trap in the cylinder by sparking twice.
By combining the dli ecu and the dli twin coil has a perfect combination for each other. I have rev a 20valve silvertop up to 9600 RPM which a normal distributor system cannot do. The dli system have better fuel and spark efficient over the normal distributor system.
Race record:-
Drag distance about 1km to 1.2 km.
20v dli vs 4age twin webber with 304 cams ae86 ( won)
20v dli vs 4g67 wira with no rev cut ecu (won)
20v dli vs 20v stock seg (won)
20v dli vs 6 speed blacktop seg with safc (won)
20v dli vs B20B honda ek (lost)
