So water injection sounds like a better and safer deal?

Wouldn't really say better or safer. Just different and in some ways slightly simpler.

Iam thinking about just sticking with the gtm tune and just turning he boost down a bit and things should be fine.. Looking forward to hearing how easy this new twin turbo install is going to be from you guys...

For reliability, go get a custom tune and explain your concerns to the tuner. Leave it a little richer and don't add so much timing. You can still get plenty of power. The Garrett setup can make far more power than the stock block can handle without meth.

I had a "in-the-shower" kinda thought this morning: Has anyone discussed doing ceramic coating on the manifolds or downpipes for their kits? I was wondering if that was a cost-effective modification, and the associated benefits with ceramic coating.

Chuck33079 · 07-10-2013, 10:56 AM

I had the manifolds, downpipes and hot sides of the turbo ceramic coated. I couldn't tell you how effective it is, since these cars run hot anyway and I have nothing to compare it to. It wasn't too expensive. I'd do it if you have the choice.

SPOHN · 07-10-2013, 01:30 PM

I'm just going to wrap the down pipes and wastegate down pipes. I'm also working on a plan direct air at the turbo manifolds.

Dzel · 07-10-2013, 06:47 PM

I was going to coat all hot side parts and wrap the CBE UP to the mufflers

I don't see no need in wrapping the CBE. It's well beneath or back from the engine compartment where additional heat wouldn't be added.

Chuck33079 · 07-10-2013, 07:41 PM

I'd stop worrying about it after the downpipes end. By then you're out of the engine compartment.

Dzel · 07-10-2013, 08:29 PM

Well here's my reason for that. I heard if you completely wrap everything you have more potential for flames to shoot out I know it sounds stupid but I wanted to try it. I figured since I'll be under there anyway I wanted to bust this myth.

I ordered the IWG and I have a 7AT, any downside to that?

elperuano · 07-10-2013, 09:20 PM

The 7at lol
