They're just individual coils bolted on the valve cover.
ign1a smart coils.
Curious as to why you went T3 .81AR. That thing looks tiny compared to the compressor and will make the car surge more at low RPMS in 3rd or 4th gear. Also how much boost do you run now? Estimated power level near what you had on the HX40 with more tq? Your clutch doesnt like it but it sounds fun XD
It's still a T4 so no surge
borg just likes to make the compressor housing crazy big
wastegate was like 17 maybe high 18.
it's hard to compare both turbs because of the boost ramp but at least
i know that borg is like a train pulling vs a 2 stroke dirt bike that falls on it's face with holset.
Holset now feels like homeless persons turbo. laggy and it was too small for my goals.
engine is now apart and waiting for twin disc. imo after 19psi the holset wouldn't feel any faster up to 28psi (Where it broke)
power i can't really say but the borg made the car funner and faster at a slightly lower psi
