a few q's about d15z1 turbo setup
 

Okay first of all i have a d15z1 in my civic and i am turboing it ,the turbo is a hybrid of the ihi rhb5 vf8 ,with the smaller rhb5 vj6 exhaust housing with the bigger vf8 wheel ,I did this because i already had turbo'd the car and blew the seals in the vj6,So i didnt want to make a new adapter plate and down pipe for the vf8.I am deciding if i should go 440cc injectors or a extra 750cc what whould be cheaper ?And easyier to tune?The extra injector will be controlled by a pressure switch.Also the 02 sensor has died and im not willing to pay $350 for a oem 02 sensor !,Will the Safc be able to work proply with a faulty 02 sensor???Also i found this product which seems to be ideal has anybody used this before??

my little brother has a 94 vx hatch, first and second gear it scoots pretty nice, but i totally dies is 3rd. i doubt youll run a itr with that motor and tranny setup. the gearing is too tall.

never seen a vtec-e under boost.. I guess it should work, I am sure nobody has done a setup like what you are doing, so with that said, stop worrying and do it. Bolt that ---- on and see what happens, more than likly it will work just fine.

I would get another o2 sensor, go to a junkyard and get one.

Should you keep up with ITR's? No problem... (if their stock heh)

yeah they have really tall gearing 60km first 110 second 140 third.And u really feel the small displacement up top .Because of that and it's redline of 6200 i chose to put a small turbo hybrid so it will still be on full boost throu gear changes.Also I live in australia and our vx model is named VEI which is in sedan and hatch form,mine is a sedan but lighter than normal sedans,Also vei was a limited model here and didnt sell to well .Ive rang every honda wrecker in my state and none have wrecked a vei before.So it's imposssible to get second hand parts for it ,thats why i was looking at getting the o2 simulator.If any1 has a 5 wire heated oxygen sensor or can get me one then il buy it .I might do a d15b or d16z6 conversion later on when i get a bit more cash,but not for a while

thanks for your help
