Hey guys, posted a while ago about my car running rough, hasn’t run well since I bought it.. it stumbles bad at 4000rpm, puffs black smoke and falls completely out of power up top.. however idles fine and runs fine when I stay out of boost with the exception of a slight bog off idle (rpms dip slightly when I crack the throttle)
Thought It was a boost leak so I got a bunch of gaskets and spend the last couple days pulling the engine.. engine is now on a stand and my driver side turbo looks like it may have eaten a nut or something, I’ll post a pic
Question 1: could this damage be causing the stumbling issue? Seems to pull hard up to 4000 rpm but it’s never run right while I’ve had it so I have no comparison
Question 2: where should I go from here.. budget is not endless but keep in mind this is not a daily or a dedicated racecar.. more so a project/ weekend thrasher
Options are to get some new turbo centre sections.. not a fan of having these ones rebuilt as I’ve heard their second life is usually short, maybe you guys have a different opinion? Or, the option I’m leaning to.. some Godspeed turbos off eBay.. ones I’m looking at are comparable to the gt2860, what’s the opinion on those?
