i thought the middle two cylinder lean out was due to the center feed manifold, hence the prob was still there in a way for gen3's but maybe because of the better ecu and perhaps stronger pistons/lower compression and rings it didn't destroy itself as easy as the gen2's?

so, how far you gonna go with the rebuild?

No not running any individual cylinder trims.
I thought it was more of a manifold problem as well.
At the moment im thinking of
Pauter rods (5s size)
cp pistons
264 hks cams, springs and gears
w2a intercooler
engine oil cooler
maybe a caldina intake manifold
unsure of what clutch

Any recommendations?

Gen3's have roughly the same problem as Gen2's in regards to the lean out, but maybe not as severe. Looks like the tuner went a bit too far looking at that. He probably should've stayed on the lower side of 11:1 C/R to compensate or made use of the Autronic's individual cylinder abilities.

A different intake manifold would be good in the future.

Andy sorry to see all this mess man but i guess you can now get the bigger engine done
need a hand let me know iil come down and help even if its just handing over tools

cheers

clutch. OS twin plate. Forget those single plate clutches.

Dasic1...what power/boost were you running when the stock internals failed? It's Gen 3 right?
I'm interested to know because my engine is coming out soon to make it easier to change the clutch, timing belt and cams, and I'm wondering whether to spend the extra $ to rebuild it while it's out, in anticipation of if breaking on stock internals when the power is increased to around 240kW atw.

Ive been doing some research and looks like a twin plate will be the way I go
What options is there for intake manifolds?

robk Yeah its a gen3. It made 187.8rwkw @20 psi.
I was also planning on removing the engine for clutch, cams and timing belt and was considering if I should go that step further as well. When stripping the motor I also noted that the timing belt was starting to brake up after 117km

Maybe someone else can recommend what sort of power a good condition gen3 could make. It wasn't from the power that damaged this engine

purple5ive Thanks. Most of the hard work is done till I put the motor back in.

Decided im going to weld up all the unused hols and remove all the nut on the firewall and respray the bay while the engine is out

caldina suits Melbourne:)

custom suits every other state imo.

so your going for a reasonably priced engine or full on priced engine? i think the pauters would be the expensive option.

if i were you id be doing eagles with cp off the shelf pistons for the 5sgte. means its all off the shelf and cheaper.

twin plate for sure too. singles are crap......

I just got a quote from WTF and its wow
The only reason I was thinking pauters was they come in the 5s size. but lots of people do run 3s rods without problems.

How much better would the caldina intake be than the gen3? Id be screwed anyway I think if they looked with or without a std manifold.

Thanks for the info mate, mine's actually a Gen 2 though.
When you say the power didn't do the damage, do you mean that the tuning was simply too careless and therefore too harmful to the engine?
