joostvdw Posted December 12, 2007 Share Posted December 12, 2007 the heads are almost the same, combustion chambers, valvetrain and all that is the same (cams may be different, depens on donor vehicle) the PS turbo heads have an extra oil passage for the turbo on the backside which can easily be plugged if on a NA engine, the other way around is a bit harder since you need to drill the port or get your oil from somewhere else.

Gloyale Posted December 12, 2007 Share Posted December 12, 2007 The major difference is between MPFI and SPFI/Carb. Not nessecarilly whether it was turbo or not. All turbo ea82s are MPFI, but not all MPFI are turbo (XTs and early GL-10s had MPFI non turbo) MPFI heads have dual intake ports, and use a completely different intake. Won't bolt up to a non MPFI. All other EA82 SPFI and Carbed used a single ort for intake, adn can swap intakes easily(carbed or SPFI) but again won't bolt up to the MPFI manifold Quote Link to comment Share on other sites More sharing options...
subiemech85 Posted December 13, 2007 Share Posted December 13, 2007 was thinking of the EA81T Not always. They are for EA's.... GD Quote Link to comment Share on other sites More sharing options...
GeneralDisorder Posted December 13, 2007 Share Posted December 13, 2007 was thinking of the EA81T Right, but on all the rest the injectors are in the manifold. So that really only applies to those weird EA81T heads.... GD Quote Link to comment Share on other sites More sharing options...
