@Lucasabt

Have you had a look in the Fabia Project section at some of the members Fabia Twinchargers that have upgraded engines installed.

Ok, im just worry about i have different engine than CAVE CTHE 132Kw, when i put 211hp from APR, im worry about engine broken, because i read that 132kw have diferent and stronger parts becose more power than 140ho etc. thats why i asking

So don't modify the engine, just leave it alone, you've already blown one up, why risk it with another.

If that ETKA says that i will believe her, so u think that CTHE and CAVE (132kw) have same parts like ctha, bmy blg etc?

 

The engines I've looked at and linked you to on ETKA are CTHD and CTHE. Are you viewing this on a phone? Sometimes that results in some missing columns of information, important ones like the part codes!

My previous engine gone because, peace of spark plug fall into cylinder, and valve broke, Now my new engine have 20 000km, its like brend new, my previous have stage 1 too

In my experience it's far more common for a dropped valve head to break off and damage the sparkplug than the other way around!

 

A dropped valve generally happens if the engine is over-revved, usually during an accidental down shift.

it happened to me when I was going uphill, 3000rpm+- piece of spark plug stuck under valve and then valve broke, engine goes on 3 cyl

 

@Lucasabt Commonly the fail happens when under 3,500 rpm when under acceleration and on Supercharger & Turbo which is from 2,800-3,500 rpm.

 

the APR Stage 1 is no issue with a CAVE or CTHE. 

It is actually better than the standard VW Group / Skoda map.   That is when it is with a sound engine obviously.

It was not a remap of the CAVE engines that killed them. Plenty were done and were less prone to failure than the standard from the factory with the first spark plugs they came with then the 2nd ones they went to.

The early CTHE's were not problem free, the failure rate was the same as the CAVE's they had just replaced. Then there was an improvement.

We know with the 1.4 TSI Twinchargers about the one plug that gets burned out, so we can forget what happens with other engines commonly and stick with these ones.

But i dont know which code i have, :/ i know just CTH and 20-3-2015, but as someone wrote, CTHE. And skoda fabia   end of production is 2014, so maybe i have engine from tiguan or something like that, so u think is apr stage 1 save for my engine?

I cant english too good, so i understand just something😬😁 so sorry for repeating my questions etc. 😄

All the cranks are forged steel, nobody uses cast cranks any more and I would expect the cams to have different part numbers to denote different lift and ramp geometry.

However it is possible the pistons and conrods are different, many modern engines use sintered rods with cracked bearing caps and cast pistons.

 

I think you may be traumatised by the expense of the engine failure but as wino says the same part numbers should convince you.

Here is just steel crankshaft, not forged, so mine can be just forged too

I really don't think we can take this much further.

In the old days cranks were often cast, nowadays they're all forged, these are the only two ways of making a crank.

You seem to be having a lockdown meltdown, go and have a lie down and stop thinking these pointless negative thoughts.
