Recirc valve goes from plumbed in just before the throttle body, and returns to between the AFM and turbo. You'll want a vacuum source too for it from the inlet manifold. -
Thank you. Can you please check where should I add hose in intake pipes? From recirc valve back to intake? I upload photos on imgur. In front of turbo inlet, after maf/ right after turbo outlet / or it doesn’t matter? https://imgur.com/a/wC4y8ro -

I'll go ahead and replace it then just for peace of mind. I've never seen my coolant temps go over 82C, so like you said, should be fine. Cheers! -

Wrapped up my catback modifications this morning. I'm loving the pie cut turn down and oval muffler. -

Stock ECU with no recirc valve is a bad, bad combination. Hot wire MAFs cannot deal with reversion, even if you don't vent to atmosphere it will shoot back out when the throttle snaps closed all the way out the compressor inlet and MAF before getting sucked back into the engine. It double-counts the air, the engine runs way too lean and stumbles if it doesn't die outright.
