OK.
![](./images/smilies/spacer.gif)
now i have been through all the documents online.
![](./images/smilies/spacer.gif)
listened to everyone about these engines.
![](./images/smilies/spacer.gif)
yet im finding differences between the engines.
![](./images/smilies/spacer.gif)
and not just the odd bracket here and there.
![](./images/smilies/spacer.gif)
Timing belt.
![](./images/smilies/spacer.gif)
thats the first one.
![](./images/smilies/spacer.gif)
the JDM has a Sprung tensioner, the UK has the Oil Pressure fed one.
![](./images/smilies/spacer.gif)
, the rocker cover is different, well more the oil breather system.
![](./images/smilies/spacer.gif)
the JDM one is a longer drawn out affair.
![](./images/smilies/spacer.gif)
it seems to make the gases condensate before allowing it to reach the inlet manifold.
![](./images/smilies/spacer.gif)
the UK spec one is just a plate with a hole in it.
![](./images/smilies/spacer.gif)
all i can see that JDM one doing is making the emissions slightly better.

Cam shafts dont look the same in design.
![](./images/smilies/spacer.gif)
the UK spec ones are like the 3S-GTE versions.
![](./images/smilies/spacer.gif)
they have notches inside the cam cover area that align with notches on the cam clamps.
![](./images/smilies/spacer.gif)
the JDM doesn't have these.
![](./images/smilies/spacer.gif)
it also has multiple holes on the Cam pulley ends to put the Knock pins in.
![](./images/smilies/spacer.gif)
the JDM ones only have 1 pin hole.
![](./images/smilies/spacer.gif)
Sump on the UK spec has the Oil Level sensor.
![](./images/smilies/spacer.gif)
JDM doesn't have this.
![](./images/smilies/spacer.gif)
Inlet manifold, the UK spec has a 5th Cold start injector.
![](./images/smilies/spacer.gif)
the JDM doesn't.
![](./images/smilies/spacer.gif)
also the JDM has a Lambda sensor, the UK doesn't.
![](./images/smilies/spacer.gif)
what this all means though im not quite sure.
![](./images/smilies/spacer.gif)
which is the more reliable? which would be better power wise? I like my MR2.
![](./images/smilies/spacer.gif)
but its beginning to be a bit of an annoying headache.
![](./images/smilies/spacer.gif)
and i haven't even driven it yet.
![](./images/smilies/spacer.gif)
.
![](./images/smilies/spacer.gif)
still at least i got the locking wheel nuts off.
