oh dear lol

Well it was my fault, seems like 88k turbos don't like being remaped, no idea how close it was to death before the remap however, only lasted 5k after i got it done, first i got lots of oil in the exhaust then no more boost, it had some interesting compressor play and either a very worn bearing or a snapped shaft.

ok...

It does serve a purpose unlike some stupid spoiler on a corsa/nova etc.

Not in a 1.8T it doesn't, seen as the engine won't run correctly with one fitted.

I hope you got a deep wallet.

It has one as standard.

I meant it needs a recirc as opposed to a dump valve

It goes pssshhhht when you change gear and takes the engine out of manufacturers spec.

Be very careful !

So old school jap cars use them but modern turbos don't?

Depends on how the car monitors air intake / pressurised air after turbo and re accounts for pressurised air not used.

Running a vent to atmosphere dump valve on a 1.8T will cause a mismatched amount of air to pass through the MAF, causing the engine to not run correctly at all.

So what's the alternatives. Can only leave it standard with a recirc?

I would assume you can buy an aftermarket recirc, but I dont know if it would offer any advantage if the rest of the engine was stock

For the case of the 1.8T?

The standard recirc valve is plastic, and prone to failing on remapped (and sometimes stock) cars. The Forge 007p is a very VERY common upgrade for stock and modified cars alike. These also have the bonus of interchangable valve springs, so you can tweak it to match the boost threshold of your map/turbo.
