Hi guys . Have lost a significant amount of low and high end power in my 93 sw20 turbo. Feels like it struggles to get to 3000rpm when it use to put me in my seat when it was fine. Im new to the turbo versions so I could be wrong but I'm heading towards an exhaust leak or boost leak. I still have boost and it spools up but doesn't feel at all like its putting power through.the engine has also started to sound very lumpy and the classic "tractor sound" and when accelerating I can hear a lot more air type noise from behind. I was feeling around my engine bay and felt a lot of air coming from this section of the engine. Not from around the turbo but under that shield(see attached) hopefully someone can help out. If I can supply more info so you can help I will

Thanks Matt

Check along your intercooler piping that one of the couplers hasn’t bursted off or something, or it’s possible you have a crack in your exhaust manifold

Did some tinkering today and found some really loose bolts on the manifold I think. Tightened then right up and the engine sounds like its back to normal. Will give a test run later to see if its boosting well and has the power back. I did however check all the intercooler piping and it seems to be good.no cracks and nice and tight
