hi my brother has a 93 civic vx and his engine finally died after 170k miles. he took it to a shop to get a new engine put in. the put instead of a d15z1 a d15b. but only the long block. they used the vx ecu ,intake mani, exhaust mani, tranny.
from what i researched, i called the guy that did the work and told him that these parts needed to be replaced. he said that it didnt....
we bought a p08 ecu and installed an a d16y8 intake mani. soon to be installed.
my question is
1. the engine didnt come with the 1 wire d15b 02 sensor so the 5 wire d15z1 o2 sensor is being used.
is this ok?? or will it cause harm..
2. is there nething else that needs to be replaced.

i have been doing research and i could use ne help.
i am not too familiar with civics. i own an S2000
so any help with this problem is greatly appreciated
thanks in advance
justin

oh and it is boging at low rpms but once above 4-5 k it runs smooth.. could this be fuel injectors or the fuel pump????
i dont think they have been replaced ever...
thanks

TTT

 

Bump .... NEONE?????

 

if he reused your vx ecu then you will need to run the corresponding o2 sensor which is the 5 wire o2 sensor.

all the parts are interchangeable on the longblocks so he reused all the parts off the vx. check the timing on the bogging issue and plug wires/sparkplugs

 

hey i got a jdm d15b swap in my car too. but im runnin a p28. im just wonderin if the p08 ecu is supposd to be the correct ecu for the 3stagevtec, is ur d15b vtec? if so ur ecu must be jdm also. where did u get it at?

 

yeah its the d15b.
he used the vx ecu.
but we replaced it with the P08 ecu...

 

from what i read, a d16 y8 intake mani will bolt up to d15b... but is there any modifications needed??????
i read posts that say 2 different things..
i am confused
