i have a d16y7 the injectors are 180cc stock. ny friend gave me the injectors out his d16y8 and the stock injecters in there are 240cc. if i put them in my motor will i have a problem or will i blow out my ecu please help me out

 

You're going to run rich because the ecu thinks the injectors are only 180s but you have bigger ones in. The ECU should compensate to some extent in open loop, but in closed loop I believe it will just run the base map and won't compensate at all. Unless you get a VTEC head and the Y8's ECU, don't mess with it.

Just dumping extra fuel in won't give you more power. Hondas already run rich, if anything you should think about tuning and pulling a tiny bit of fuel out. Then you can put the 240cc injectors in and set it up to run those if you really want to.

 

itll run a little richer but i was thinking all d's had 180's?

 

nope. almost all b and d-series injectors are 240cc. very few are 180's. the only ones that have the smaller injectors are the 88-91 d15b6, 92-95 d15b8, and 96-00 d16y7.

 

ecu may blow out, make sure you have a jack and lug wrench in case it does.


no, not really. nothing catastrophically bad will happen. but i am curious as to why you want these injectors?

 

i did full exhust work headers intake mani etc and wanted those injectors since mines were going bad
