Thunder550...

Will this turbo set-up, make any more power or be more effiecient in some way compared to your old set-up??

 

Should cause he can turn the boost up higer (like he needs that) and the manifold won't crack or warp from the extra heat, plus it looks pretty

and as stated above dangerous things happen from boredom

 

I don't know for sure. The manifold design should be a little more efficient due to the position and location of the runners. I am also going with a 3.5" downpipe as opposed to the original 3" one, so there should be a little bit less restriction after the turbo. Because of the new position of the turbo, I was able to get rid of a 180* bend in the cold side piping too, and removed about 3 silicone couplers in the process. That should prove to be much less restrictive as well. Whether or not those make a noticeable different remains to be seen.

 

LMAO!

 

kinda looks like you too chris

 

Since you all ready have everything apart you might want to look at the passenger side exhaust manifold. I noticed that mine necked down to 2.25 at the flange, and the ports are smaller than the gasket and head opening by 1/8in on the top and bottom. Maybe mine is just a bad casting, but given your cubes and amount of boost potentional it might be worth breaking out the dremel tool and gasket matching the ports and opening up the exit flange to 2.5in...

 

You're talking about the log manifold? Kyle already took care of matching all of the runners to the flange and everything.

If you're talking about the stock driver's side manifold, that's probably a good idea. I'll check it out.

 

I was talking about the stock manifold.. It may or may not make any difference but, on your build I would check it out... See pics below.

All the black stuff is where the manifold is smaller than the port and gasket, I am going to grind it all away...




Sorry for the blurry pic, but as you can see it is smaller than 2.5... see all the black stuff, that shows where it is smaller than the flange...

 

I'm surprised you are still ussing a log manifold type on a 408ci.There will still be alot of pressure on the pass side exhaust valves.

 

Chris, I recommend adding a 1/8 NPT port on the passenger manifold if you are interested in knowing what your exhaust pressures are. I did that to my manifold... but plugged it for future use as my lil ole 5.3 isn't pushing enough air through my for me to be worried about it now.

Manifold looks good
