i was wonderin if y7 internals would fit into a d15b1 block with no mods involved if so what kinda performance would this bring me???need help lol because i need a motor and was thinknin about buildin it like this its some thing new around where i live and different so....

 

figure out why one is a 1.6 and the other is a 1.5 and there is your answer

 

so ur saying it wont work with out modding it???

 

what was the difference you found out? rod length or piston bore?

 

alright, to make it easier on you i will just tell you that the difference is in the stroke, the 1.5 has a 84.5 stoke where the 1.6 is a 90. so taking those y7 rods and pistons and putting them in then d15 block would ensure a heavy make out session with your pistons and head

 

so good or bad idea????

 

well if u think your piston beating the **** out of the bottom of your head is good then go for it but if u are like some of us here and think metal slapping around is bad u wont.

 

what if i just use the pistons not the rods any difference?? if nothin then rods and not pistons what ever works best????

 

wait better yet lets say i used the rods and pistons but i shave the top of the pistons to fit just perfect so it does not smack the **** outta my head????please say this will work

 

your compression will drop to around 7.9:1. what is the reasoning behind wanting to use the y7 internals? its pretty much a waste of time. what are you lookign to do? raise or lower compression?

 

 

more power and to be different but i guess if it lowers comp whats the point

 

any suggegtions to make decent power with these two blocks i also have a z6 head

 

y7 pistons with b1 rods maybee...?? should work i dont see why not the bore aint different the stroke is so i would just have to change the rods

 

why dont you just put the vtec head on the y7 block?

 

The best thing for you to do man is just to either, buy another single cam OR take the pistons off the y7 rods and put them on the d15b1 rods. because if you think just putting the y7 pistons and rods in a d15b1 block is going to run right then your wrong!, thats going to be valve tap from hell! Then your going to be out of a perfectly good head and bottom end.

 

but the y7 pistons will drop the compression giving him less power
