New to gassers (twin turbo lq4 S30) I'm building a twin T61 MP LQ4 77' 280Z and im trying to figure this whole O2 non O2 wide band non sense out.. I come from the diesel world and 600 RWHP is as simple as big *** injectors and nice turbo.
Ive heard of people running no O2's and people who swear by them. closed loop, open loop.. Dual A/R yadda yadda. The car came with a innovative LC-1 and two O2 sensors. I'm not going to get into tuning this thing as i will leave that to the professionals. I will build it, they can tune it.
The question i have is this:
What is the best way to set this car up so that it will run like a TOP? how should i place everything so that when my tuners put it on the dyno he can blow and go?
Any and all advice and opinions will be listened to.
take in mind the details of the car:
lq4
twin master power t61
injector size TBD
3" pipes W/ x pipe
truck PCM

Keep the pre-cat O2s in place and remove the post-cat rear O2s. Install wideband bung on driver side close to the other O2 sensor about 6" downstream of it I like the narrowbands to maintain stoich while in closed loop. Helps for those hot days. Just my unprofessional opinion.
Nice blue skirt and car. Always loved both of those body styles
