This is an upgrade I will be doing when I go for bigger power.

I will have to sit down and put together the price for the new pipe kit package. Will post it in the original post once I have it all figured out.

I also just ordered a bunch of the extruded elbows used to make these new manifolds.

Sweeeeeet

Hypothetically is I switched to the new turbo cover and piping would I require a re tune? Or will the s-cover not fit? I assume the s-cover will flow more air, would this screw up my tune? I am fine with my setup, but I like the idea of reducing the amount of oil lines just to simplify things.

If I go this way I am definitely retuning but it should just be a quick touch up and nothing like the initial turbo tune.

I just did some light reading and most say the s-cover helps more in higher boost situations, which I do not consider 10 psi high boost. In my mind I would switch to new IC piping and to the thermostatic plate, eliminating filter relocation and 2 oil lines. If the piping length is about the same and stick with an e-cover I cant imagine a re-tune would be needed, this is the route I think I would go.

The only reasons I would consider it would be to run a bigger air filter and get down to only four oil lines (I currently have 6 oil lines instead of 5 like the standard kit because of the GReddy thermostat).

My tuner is like 10 miles from my house and a quick retune would probably only cost me an hr of dyno time. When it's that little I'm more than willing to get it retuned.

Im think the way Sasha worded things the s cover will not fit with the turbo location with the v1 manifold, at that point I think it will get too expensive to justify, I think I would stick with the e-cover and the new piping.

Now that I reread that I agree. It still might be worth it for the oil lines depending on the cost he comes back with but not for 10-15k miles when its time for a filter change

Very nice! great work as always

who is next??? ;)

It amazes me that the best turbo kit for the 370 (IMO of course) can get better. Props to Sasha!

Thats correct. I am running what you could call the V1.5 kit right now. And right out of the gate I am building 0.5PSI more boost with no changes to my boost controller. So the kit is able to push that air more effectively than it has done in the past.

Are you still running the original PT6266 or was the new turbo housing part of the V1.5?

You need a whole new turbo manifold to be able to fit the new turbo housing. I am running the original turbo, its just clocked different and the elbow that was welded to the outlet of it is now removed.

Cool. Just wasn't sure if Sasha sent you home with a new manifold or not for your efforts. Nice to have real results that the changes do indeed increase efficiency.
