OK.
now i have been through all the documents online.
listened to everyone about these engines.
yet im finding differences between the engines.
and not just the odd bracket here and there.
Timing belt.
thats the first one.
the JDM has a Sprung tensioner, the UK has the Oil Pressure fed one.
, the rocker cover is different, well more the oil breather system.
the JDM one is a longer drawn out affair.
it seems to make the gases condensate before allowing it to reach the inlet manifold.
the UK spec one is just a plate with a hole in it.
all i can see that JDM one doing is making the emissions slightly better.
.
Cam shafts dont look the same in design.
the UK spec ones are like the 3S-GTE versions.
they have notches inside the cam cover area that align with notches on the cam clamps.
the JDM doesn't have these.
it also has multiple holes on the Cam pulley ends to put the Knock pins in.
the JDM ones only have 1 pin hole.
Sump on the UK spec has the Oil Level sensor.
JDM doesn't have this.
Inlet manifold, the UK spec has a 5th Cold start injector.
the JDM doesn't.
also the JDM has a Lambda sensor, the UK doesn't.
what this all means though im not quite sure.
which is the more reliable? which would be better power wise? I like my MR2.
but its beginning to be a bit of an annoying headache.
and i haven't even driven it yet.
.
still at least i got the locking wheel nuts off.
