Need Advice on 4.7 Stroker Build

[shawnbstrokin]

I purchased my first Jeep Wrangler 2004 4.0 and I am looking to stroke to a 4.7. It currently has 68,000 miles on it. I know what I definitely want with some things regardless of price but I need some assistance with other things so please share advice. Thanks.

Jeep 4.0 (Stock 190 HP)

1) I definitely plan to purchase a Hesco 4.7 stroker kit (Raise to 260 to 270 HP?)
2) I definitely plan to purchase a Hesco aluminum head (Raise an additional 30 HP?)
3) I definitely plan to purchase Borla Headers due to higher grade of steel (Raise additional 10 HP?)
4) I definitely plan to purchase a Borla Cat Back system (Raise additional 10 HP?)

5) I want a cool air intake system (Raise additional 10 HP?) Which one or ones should I consider and why?
6) I want a larger throttle body. Which size? 62mm or 68mm? Different suggestion?
7) Would a throttle body spacer help with this set up?
8) What else do I need to do this right?

Thanks for any other additional feedback or comments!

To get 260-270hp you'd also need items 2-4 as well as item no.1.

Look for the CAI system that has the biggest filter, a heatshield, and smooth pipework from filter to TB.
Enlarge the plenum inlet of your intake manifold to 68mm and go for a 68mm TB. A spacer won't help you.
You'll need a set of oversize injectors (27lb'ers) and a custom tune by FlyinRyan to optimize your set-up.

Save your money on the head purchase for a few months.

You could port your existing head instead.

It is a 2004 Jeep Wrangler 4.0 with 68,000 miles and Hesco seems to be the best way to go for me because I want high quality parts. I plan to keep it for years to come as a every day driver and eventually a pure weekend vehicle for trails. I plan to do some light trails for now but eventually do more advanced trails down the road. I would like to stay between $7000 to $7500 if possible but here is what it looks like so far:

1) Purchase a 4.7 Hesco stroker kit ($2570.00) plus cam shaft ($267.00) and timing set ($169.00) plus aluminum head ($1995.00) in addition to having work completed (Labor Cost to do all work?)

2) Purchase a brand new 4.7 Hesco stroker engine ($8999.99) in addition to having it installed (Labor cost to do it?)

I don't have the skills or time to do the work myself and want it done right so I have to decide to go for the stroker kit in the near future or hold off and buy a new engine but I am interested in knowing what the difference would be total cost wise with labor factored in for both.

Blimey, $9000 just for the engine itself and 270hp? Maybe you should consider the popular (for the Wrangler) 6.1 Hemi V8 swap instead and you'd have 420hp.

While Hesco has a top nothc product there are other companies that are good as well but far cheaper. Or put together your own kit. I wouldn't pay 9k for a stroker.

Rather then the parts how about having Hesco simply build you an engine ? Bet it would be cheaper.

It would be cheaper if you opted out of buying their $2000 aluminum head but since Shawn's engine still has a fairly low mileage (68k), I'd be inclined to leave it alone and build a stroker out of a tired (but still running) junkyard long block instead.
