I have carried out a quick search but not really found an answer to my question.
Apart from the shorter inter cooler pipework, at what power level does the reverse inlet mod become worth it? And i'm referring to the 2.0 classic engine here.

 

its not worth the work involved fella,

 

Even whilst I have the engine out for forged re build and accompanying mods to take it to roughly 400-450 bhp? Maybe more in the future. Would you still leave it? Cheers.

 

Honestly the only gain is a cosmetic one fella

 

To be honest with you mate if you also flip the intercooler then the shorter pipework overall might aid in slightly quicker spool up, But mainly I say looks nice, Also If you was to run a bigger turbo on rotated pipework then it will help as you will have clearance round the back.

 

Always makes me laugh this
As its a mod I want to do .....
Ask all the tuners etc "na no point"
The the next race meet etc there working on their cars bonnet up and low and behold reverse inlet

 

How is it even done?

 

Been told very simple on let's call it sti 8 /9 blobeye
Bracket for altinator remove a/c and simply spin round
Then cut pipework to suit

 

From what I understand also, it's not that much work either, alternator being the main work.
Air con has already gone, flipping the front mount is already on the list at the same time. So whilst doing the other work I may well give this ago along with some 10mm thermel spacers.
I think this mod also allows a neater looking IC pipework route.
