will a d15z1 head work on a jdm d15b? and if it will, will it increas my gas mileage? because isnt the Z1 the more econimical 1.5?

 

anyone?

 

yes, and yes

 

thanks. hope you are right. ha.

 

how about the ecu though? will i need to get a z1 ecu?

 

believe so, get a po7 ecu, otherwise i dont think the lean burn mode would work the way as used for the stock z1.

 

read on a post in the del sol section that you can use a p28 also, can anyone confirm or disprove that?

 

both the p28 and the p07 will work, but i would use the p07 since the p07 is the ecu vtec and the correct fuel curve and such

 

well i already have a p28 lying around is the thing. this head is manely just a replacement so i can slowly rebuild the original jdm head i have and still have my daily driver, its gonna be a learning experience too. the thing i am worried most about is getting the timing right, cause i have never had to time anything other than my chevy small block. any forums you know of on timing basics so i dont [freak] my **** up? the timing belt i have will work with the z1 head right?
