    i have a 90 civic si (d16a6) and i found a d16y8 complete motor with a spun bearing for cheap. problems i want to put the head off the y8 on to my a6 block. i dont know the history of my car and the odometer says 313xxx km its a lot. it doesn't burn a drop of oil but will the higher compression be ok on the old block if it hasent been rebuilt?and could i expect about 135 horses?

    If it is anywhere near 300,000 miles I would definately rebuild that whole motor and the head, I don't know your power goals but the y8/a6 mini me would be a decent turbo steup if you decide to go that way.

    i know my a6 was getting pretty old the valves were out of ajustment and things like that. i think i may use the whole y8 motor and just replace the bearing and rebuild my a6 for a high pefromance set up. i dono yet.

    do you really get that much of a hp increase?!?cuz my stock d16a6 had like 102 and i put a z6 head,thatd be pretty sick

    you cant just replace the bearing,,you should replace all of the bearings,which would lead to lower end bolts,gaskets and seals..so save some time and money and rebuild the a6

    i used a calculator and it says 300,000 km is 186,411 miles so my 90 civic si as its standing has about 186,411 miles

    the d16y8 with the spun bearing has about 78,914 miles

    so why cant i send the y8 crank and get it checked over at a machine shop and put new bearings in and call it a done deal?:confused:

    So my best bet is to rebuild my a6 block and put the y8 head on? Should I rebuild the y8 head with 78,914 miles on it?

    I'll probally not rebuild the y8 head because i'm on a sort of tight budget.
    When I buy head studs do all d16 engines use the same studs or do I have to buy them for the a6 or y8?
    And head gaskets, do I buy a y8 or z6 because its thicker than the y8 I think.

    start your own thread,use the cam for the head,or go aftermarket
