Lightning conversion questions

[BLUE20004X4]

Next question: Exhaust. Probably might ask in that section but in keeping with my conversion questions I'll go here too. I am gonna build the bottom end of the engine to take the boost (basically a stock rebuild with good parts) and maybe trick flow heads or just new cams but for sure Long tube headers. Behind that I was planning on a custom y-pipe, 2.5" with hi-flows going into a single 3" catback, SI/SO JBA system. Do you think that's ok, or is it basically needed to be a true dual setup. That or go 3" from the headers back still merging into a single 3" pipe. Basically from supercharger experiences, how much exhaust is needed realistically?

I remembered another question, the idler pulleys for the supercharger, would this kit: http://cgi.ebay.com/ebaymotors/99-04...Q5fAccessories be what I'd need? Usually I don't get a clear pic, as in this case but the description is alright. Anybody have these Metco setups in theirs?

No that is not a stand alone idler system, it augments the factory system. So if you go that rought you would need to have the factory systme first. And unless your running high boost applications, its not needed. As far as exhaust. I would go duals all the way. OBX makes a nice front half system and for the rear there are a lot of options. I'm currently changing over. I will remove y pipe from long tube headers and go dual pipes back to rear with a Magnaflow X pipe and 2 Magnaflow 18x4x9 mufflers. All 2.5in. Some like 3in for sound. 2.5in probably more than enough to exhaust exhaust gases and not restrict power. my 2 cents.

[BLUE20004X4]

I keep trying to save my existing exhaust because it has been a sweet system but nothing compares to duals. I got an exhaust guy who can do the mid section with hi-flows but thinking I need that done because I have the transfer case etc. I want the Lightning muffler setup with Bassani's.

So Phil, that kit looks like it is everything I need or like cobrakit says it is a bit of extra adding to the idler pulley bracket which my purchase didn't have included. No big deal, mad enterprises has it and the other things I'll need.

Like Cobrakit said you don't even need that kit(it's an extra) if you needed better belt wrap.Like if you put a smaller pulley up top you might need it.
Other then that it's a wast of money.

looking at wanting to goto either the 3 or 4 valve heads on a basic stock build up.

do some more research, the answer is NO besides trick flow heads will work just fine for a 2 valve

I had a stock y-pipe feeding a 3" SI/SO Flowmaster after I supercharged my truck, I was seeing 14+lbs of boost. I wanted to be around 12, so I had to switch out to an x-pipe and dual stingers, still 3". No problem now, and dual exhaust sounds sweet

Alright, you guys convinced me, twisted my arm, true duals it is. So, next question I have is concerning fuel rails. Mine on my truck now, stock 5.4, is this the same as a stock Lightning one or are there differences? Reason I ask is that there is a used one I found, low miles for cheap but do I need a Lightning specific fuel rail, mine now looks and works fine. Any differences or would it be worth 25 bux to put a newer one on?

As a side note, I took the blower apart last night from the lower intake, looks very clean so I was happy.

your fuel rails will be fine
