Turbo,,, reliable? If you've had an engine failure post here.

So now we have :-

Rev 1 = Three bottom end failures, 1 on number 3 piston, 2 unknown

Rev 2 = Two Number 3 piston failures

Rev 3 = Seven failures

including Brys mate who had number 4 go on his rev3

rev 3 low comp on cyl 4
same owner for 7 years meticulously maintained, yearly dyno runs showing 270 whp, been running Blitz ecu and 1.2 bar of boost all those years with no prob but now low comp on cyl 4 (110 psi)

Rev 3:
Engine 1 - Piston 3 obliterated & rod through block from running lean (had diode mod in it for FCD which rev3's don't like!!)
Engine 2 - Forged engine. Knackered crank, bearings, cams, head, turbo from powder coated rocker cover
Engine 3 - ok so far (touch wood!)

Engine 2 - Forged engine. Knackered crank, bearings, cams, head, turbo from powder coated rocker cover

I don't think that one can be allowed It broke because a load of sand got in the engine

FCD problem,... is that it ran lean as you demanded more fuel than the system could provide or it actually bu88ered with what got injected?

I think that could be added to the list as not many people would think a FCD is a big risk or any risk really.

Rev 1 = Three bottom end failures, 1 on number 3 piston, 2 unknown

Rev 2 = Two Number 3 piston failures

Rev 3 = Eight failures

looks like rev 1 and 2s are tougher.

[steve]

rev3 - low compression on no.3 (4bar) doh! - engine didnt enjoy 1.2bar like my last rev3 did - forged rebuild shortly

rev 3 low comp on cyl 4
same owner for 7 years meticulously maintained, yearly dyno runs showing 270 whp, been running Blitz ecu and 1.2 bar of boost all those years with no prob but now low comp on cyl 4 (110 psi)

not Mel's one aswell?

There's still not enough replies to make any judgement yet about which rev is stronger, however there's no doubt that piston no.3 seems to be the weak link in all the engines.

Rev 1 = Three bottom end failures, 1 on number 3 piston, 2 unknown

Rev 2 = Two Number 3 piston failures

Rev 3 = Nine failures

isnt rev3 and rev1 equal in faliures?
