it goes between cyl 2 and 3, however i think the hole on the vtec block is smaller so the jet may not fit. not 100 percent on that one, maybe someone here has tried. did you think about using a y7 head? no need for adding a oil jet, and you can just use a 1.6 belt. also you wont lose any compression either

 

Were can I buy one?
Or it's not really needed

 

buy what? a oil jet?
honda dealer

 

ORIFICE ASSY., OIL PASSAGE #15140-PM3-000 is this what i need

 

Yup, thats it. There is a DIY on here somewhere. You'll need to shave down the oil jet slightly and find an o ring to use in the nonvtec block.

 

Get the oil jet installed, install an a6 cam if you can find one and I think that would be a pretty good turbo motor. Compression will be around 8.6:1 which should give you a good amount of room to play with the turbo.

 

what would the point in dropping the compression on this set up assuming stock z6 rods and pistons. dropping the compression would only lose power and the stock z6 bottom end is still limited to around a 250 hp mark . meaning you would have to run more boost to get the same results as just boosting a full z6.
