through lie after lie from people and me pretty much learning as i go along. ive seem to have aquired the most random setup i have seen. after researching codes i found out i have a d15z1 vtec e head with a y7 block and a really short geared tranny i was told was ex.

ive researched but ive never seen this set up and the z1 is the least talked about head


any info you can give me on the head? its stamped p07-1 i thought it was a jdm vtec head cus it was originally on a block only stamped as d15b

research says its from a vx 92-95 vtec e d15z1

is the head good? roller rockers say to reduce friction so can i rev higher? what should i set my rev limit to, a stock y7 or a stock z1? does rev limit consist of the head or blocks capabilities?

i just wanna know more about this setup in general.
wether i should set vtec at 3k like vtec e or 5k like regular vtec?

for more info on the car, it is on boost and e85 with quality parts all around but stock head block and tranny until i put lsd. its my daily driver

any info is appreciated thank you in advance

 

VTEC-E and boost? Ew.

 

beleive me it was not my intention to get this head, since it was on a d15b block i thought it was a p08 head, i found out the hard way that it was a p07, i opened it up to do a headgasket change and blahh roller rockers. then i looked up the stamp and yupp vtec e .

 

Frankenstein. Get something else to match. Like the correct head to mate with the Y7 block?

 

it matches and runs. id like to make this work while i build another block.

 

Get a Y8/Z6 block.

 

i have the d15b block, i was gonna drop in forged rods and pistons

 

Got to hate those Frankeboxes.
You never know if their going to act up.

 

not too much help there but nice clip lol
