My buddy is planning on putting a turbo on his '91 integra, it has the B18A1. He has about everything he needs to put the turbo on, but I was wondering what you do about the 02 sensor? Do you use the stock one or what when you turbo it?

 

You can use the stock O2 sensor. You only need a Wideband if you plan on doing some major tuning. Is your friend using an FMU & Missing Link setup? If you had more info on the setup, we (the community) can answer your question a little better.

 

Well I don't think he's planning on doing any major tuning, he's only aiming for about 215 h.p. I'm just kind of helping him do this, I have messed with SR20's a lot, but not Honda engines. He has 450cc injectors that he is going to use from a DSM and I was reading on one website and it said that you could use the 450cc injectors and use a piggyback like an Apexi unit to tune with. I don't think he's real worried about the check engine light or anything because here in NC you don't have to get a exhaust test done on cars made before '96. And what are we going to have to do about the fuel pressure regulator?

 

Any suggestions?
