Ok so I'm building an engine with a t3/t4 swap I have 2 questions 1 about the exhaust and one about the coolant pipes. So I have a full 3 inch stainless catless exhaust I had an 02 housing made I'm using the t3/t4 log manifold and I believe it makes the turbo sit a few inches higher than stock I'm not sure just yet but I'm curious if my exhaust setup will work or if I'll need length added to the downpipe or not. Next question is the coolant pipes that run from the water pump inlet to the turbo and heater core and I'm assuming the 3rd line is a return of sorts but I'm curious since the turbo is just oil cooled if I can just run N/A pipes and water pump inlet or not?

All the coolant lines that would have run to the stock turbo get capped off or plugged. no need to replace the hard lines.

every exhaust manifold brand is going to be slightly different than the others. Its very possible the down pipe or exhaust will need to be tweaked to line up properly.

Well I ask about the coolant lines cause mine are rusted and leaking bad the hard lines that is so I was seeing if rather than capping lines and spending 350 on the turbo lines if I could just run the N/A lines that are like 50 bucks lol
