sr20 coilpack upgrade thread

[inopsey]

Since old engines have old components and the ignition system for the sr20 is aging and causing problems for many wanting to keep thier cars in fine running condition, it would be nice to have a thread about upgrading the ignition system on these cars. i know there is info out there scattered around zilvia and other places about what to do and what works, but it would be nice to have this info all in one place on zilvia



From a financal point, to get a new ignitor, coilpacks and probably a new coilpack harness the cost is going to be more than changing the system all together; just changing out the coils will cost about the same as some of these full-upgrade systems.



While some (most) of these smart coil upgrades require a standalone ecu to maximize performance, others may not.



I want to start by listing known systems sr20 can upgrade too and if people can help by adding their experience with such systems pros and cons, how to make the system work if the car has a stock ecu or aftermarket etc



it should be noted that in each case the ignitor chip needs to be bypassed either with a plug-in option or the rewiring of that part of the harness.



From what i can gather there is the LSX coil pack upgrade pros are they are readily available and not too expensive.


Also the R35, VR37, audi R8, toyota yaris, s15 smart coilpacks have been shown to work with the sr20 engine
