honestly gee....the only disadvantage i have heard in theory is in relation to excessively high revs....due to the longer rods where a rule of thumb piston/rod speed may be exceeded
but i have not seen this happen to date on our end.....even with standard 5efhe rods some have revved to 7500 rpm .....BUT the 4e is suppose to be more rev friendly due to the shorter rods and theory says its should have a higher rev limits before the rule is broken---and this may well be the case
however, when people buy forged rods , forged pistons, uprated bearings, balanced crank, etc. and properly build the 5e (or 4e)....i think this risk might be reduced somewhat as they should now be well capable of revving into the excesses (above oem rpm)
PS -i'll try to find the extract for u

Whats wrong with the 5E flywheel? We used a 5E Flywheel on one we did here recently. Only problem we have now is no one makes a Twin Disc Clutch for the 5E.
for information the 5EFE ECU will never be better thant the 4EFTE ecu....
i hve already experienced the 5EFE ECU +emanage on a T4with big injectors etc from BYP ...my car on 5efe engine with 5EFE ECU is not equal to my 4EFTE with 4EFTE ECU ...the 4EFTE ECU is the better option to run correctly on a 5e or 4e engine with turbo ...
as far as ik know a 4efte ECU could not cope with the extra displayment.Will the 4efte ecu run a 5e conversion ok on a standard ct9 setup ?

first you need to change some of the 5e sensors as the ignition is different
