    good old 7age thread ---> http://www.ae86drivingclub.com.au/bo...howtopic=20854

    after reading the entire thread agian.

    i just want to re-confirm that for a basic 7age . with no intentions to rev it beyond 7500rpm ... i can get away with the following setup

    -4age smallport head
    -4age smallport pistons
    -7afe rods
    -7a block
    -4age oil pump
    -4age 100kw ecu to run it ...
    -4age crank pulley along with timing belt part number is bt111 for a peugeot
    -4AC flywheel


    what head gaskt do i use??
    do i haveto modified engine mounts, or x member.??
    is it true that the sump fouls on the x member.??

    it has been said that it can be done but will i need to and how hard is it to modified the rods to take one of the 4a bolts, to stop the bolts from stripping at high revs ?

    this motor only need to last me 2years... motor wil be used for daily driving and weekend track thrasher... so i want to use minimal money for a good power gain over a mildly worked 4age.

    -4age smallport head Yes
    -4age smallport pistons Yes
    -7afe rods Yes
    -7a block Yes
    -4age oil pump No, 7AFE Pump (if you plan on using that timing belt listed below)
    -4age 100kw ecu to run it ... Yes
    -4age crank pulley along with timing belt part number is bt111 for a peugeot Yes
    -4AC flywheel Yes


    what head gaskt do i use?? Std 4AGE head gasket

    is it true that the sump fouls on the x member.?? No

    it has been said that it can be done but will i need to and how hard is it to modified the rods to take one of the 4a bolts, to stop the bolts from stripping at high revs ? I don't think there's any definitive information on the web about what works and what doesn't, but just remember to keep in mind that the rods are very skinny, and aftermarket replacements (that use well-sized ARP bolts) are available for $500

    the porsche belt has flatter teeth as the peogeot has the same teeth as the 4age.
    after spending 2hours looking through a book lols

    can you put a photo up of the porsche belt so people see what i mean?
    this is a peogeot one
