Building our 3.8
Has anyone tried building our 3.8L ?
I mean is there a stroker kit or any way to build up this gutless V-6 our JK's come with.
I haven't found anything. I'm not looking to get the power of a hemi out of it, just a bit more ponies. I figure it should be cheaper than dropping 20k on a Hemi swap.

You find a way to make a stroker kit, I'll buy one.
It's a matter of having a 3.8L short block sitting around to play with and have some patience with specifications. I don't think anyone has hardly looked into stroking the 3.8L, but it'd pickup the MUCH needed torque the 3.8L lacks

I was hoping some one had already heard of this being done. Maybe a company I haven't found. I'm in the same boat you are, I'll buy the kit ASAP if it come out.

Cost to install would be pricey, but I know I would DIY and not hesitate. Maybe an upgraded bumpstick would be nice too!
Ah, some day

This motor is probably fine the way it is, the real problem is the restrictive intake, throttle body and exhaust plus the way the electronic throttle functions. Bottom line is this motor is seriously plugged up and detuned on purpose.
There is a fix to make throttle more crisp and responsive and you can get headers now but I'd like to see someone create a high flow intake manifold and throttle body. There are V-6 race motors that create 300-400 horsepower with an equal amount of torque so it can be done.

It's a shame what Chrysler gave us to work with but, in my opinion there are wiser ways to improve your JK's performance besides our "macro-van" engines, look for gears that match your tire size/trail goal. Power?!?! I've seen RIPP'ed JKs (a band aid to get a "WTF" engine to make power) with tranny issues so, in my opinion if you want more power (depending on your needs and/or driving style!) get a 5.7L HEMI engine/"TRANS" swap, I'm sure it'll be cheaper and more reliable on the long run. JMHO.
