Hey
I know a fair bit about these civics and theres is a few things wrong in this post.
The canadian motors are the same as ours except some have FI and the us ones are the same with a different head (only the inlet ports).
The si ones from japan came with a d16a3 engine like in 86-89 tegs but its engine code was ZC.
All the civics in the states are the same as ours, there was no HF civic only a base one wich is equal to our base one an 1500s which is like a GL and a SI which is just fule injected and has a sunroof but otherwise the same as the 1500s
Teg torsion bars will go in if you also put the tube in but are actually softer than stock bars, the wagon civic bars are slightly stiffer and go in if you use the tubes from the wagon.
The year tegs which are simalar is 86-89 tegs. they have pop up headlights. rover 416i are the same as these tegs but have 4 doors.
In the pics the first circle should be a clock.
The centre console looks like it is out of a teg and the sensor you cut is your windscreenwiper motor.
The difference between base and GL civics is no rear swaybar on base, no boot popper next too the driver and non adjustable (up and down) steering column.
The recessed headlights came on 84-85 civics and flush ones came on 86-87 civics, no mater what specification level.
If you have any questons feel free to PM me.
