i have a sohc vtech head but how do i tell which one it is?



my bottom end is bad so im trying to find a new one but id like to know what head i have so i can try and match a bottom to it.


so i know what timing belt and alternator etc rto get for it

my block now is a b7

 

D series = D series. The head will work on any d series block and the accessories will be the same. There should be a code stamped on the upper left of the head.

 

ok awesome


so for example my b7 timing belt + alternator etc will all work on a y7/z6/zc block?

 

yes all same block.

 

someoen has a y7 to sell me

i have a p28 ecu, so im pretty sure my head might be z6


would i be able to keep the same ecu wihtout flashing it or does the fuel control and all that go off of the block so id have to get a new ecu? since y7 is obd2?


thx for the help guys :D

 

Yep timing belt is the same for all 1.6l and the alternator belt should be the same for all D series, 1.5l and 1.6l.

 

be sure to use the same timing belt as the head even if you got a different block.

 

All you really need to worry about it the head. you can still run the same ECU since you won't be changing your harness. The y7 has a crank fluctuation sensor on it so you will notice an extra plug I think. Other than that you should be good to go.

 

The 1.5l are different. I said 1.6l

 

awesome ty.

i have a friend that will be doing it for me. i just wasnt sure. guy said he has a fully assembled y7 bottom end

so i should be able to just buy the bottom end and throw the head on it and just keep everything else the same then. great. that way i dont have to buy a bunch of other stuff cause im way tight on money lol



last question. do i keep my p28 that is currently in car since i will not be changing my current head

 

alright awesome. thx for all the help and very quick advice you guys :D

 

Yes. The ONLY thing different will be the bottom end.

 

Please stop. He is only swapping the bottom end. The head is a Z6 so he just needs to swap the block and put it all back in as if nothing has changed.

 

just reuse everything else. its just the block that youre changing and not the entire motor.
