Ok so im doing a ls vtec setup both the head and the block are gonna be obd2 i actually have 2 different questions

1 is and obd1 gsr head any different than a obd2 gsr head?
2 If i get a 00 si harness will i be able to pull it in inside the car or is the d series dx harness a one peice design? Can i use the d series harness will it just plug right up to the b series?

 

99-00 si harness is OBD2b so its 2 piece..

i think any 96-98 ex harness would be your best bet, since you're going ls/vtec.. one piece harness since its OBD2a

it depends on what year your hatch is though.. if yours is 96-98, get a 96-98 harness, or 99-00 get a 99-00. just to make it easier for yourself.

 

Anyone know about the gsr head

 

bro the only diff btw the obd1 and obd2 gsr head are the injectors...... all obd0 obd1 obd2 heads are the same

 

o damn
