Hi all i im in the process of building my 4g64 / evo 7 head , the block i sourced did not have a crank pulley so i have looked around to see what was available O.E.M and aftermarket but i cant seem to find an aftermarket one for the 4g64 7 bolt ? ATI , fluidamnper etc... only for 4g63

I will be running 100mm crank Manley TT , magnus 156mm rods , Mahle stroker pistons and will run 100 octane fuel with aquamist HFS3 , Map EF3 and stock manifold ...
It will be a weekend warrior with the occasional track / drag meet .

Also i know its probably been mentioned or i should have researched it but the EVO 7 gearbox is strong but at what level or HP rating should i consider upgrading it ? and Transfer case has issues but would 500WHp cause problems or should i upgrade ?
im in Australia , Melb and we dont have a great deal of places or people to talk to so any advice is welcome thanks

 

The standard Evo 4g63 crank dampers will work for you sir
