Thinking about making a street beast

[rjstiles]

Howdy,

I am thinking about turning my XJ into a street machine to try some racing kinda like the X games Rally course. Some street and some dirt elements to the course.
I want to add a bunch of horsepower/ torque and make it handle better.

I have a 2000 XJ 4dr 4x4 4.0 auto.

Any ideas?

Thank you in advance for you input

Buy a corvette ;) There is not really alot to be gained from the 4.0L so please clarify what you mean by "a bunch".:D

Stroker and/or turbo for the power, lower it w/ some stiffer springs and good shocks, bigger swaybars, poly suspension bushings, limited slip, better brakes, lower profile tires, weight reductions, and the list could go on. . .

Ditch the idea on the 4wd pick up a 2wd and use it... that said follow Gradons plan and you would be good to go.Bump stop it correctly and trim fenders a bit. Check out jeepspeed section or just google it. You can hall butt in a 2wd set up well even in the dirt.

Build a 4.6 stroker, swap in a manual tranny, and lighten it as much as possible for starters.

I was reading somewhere that you can add 150+ horsepower to a 4.0 with the right additions.

E3 sparkplugs 8 hp
Nology plug wires 6 hp
MSD box 15 hp
K&N filter 12 hp
Aftermarket air tube 24 hp
Headers 20 hp
Catback exhaust 15 hp

There's 100 extra HP! ;)

Except he doesn't have wires nor a distributor.. so that is at least minus 11 hp + 20 for the missing stickers. Nor can he use hearers... so another 10 there.

[JJacobs]

To use the Nology wires you have to put in an old style distributor.

Seriously though 150HP worth of mods? Not going to happen without boost or n20. Sounds like a magazine pimping their advertisers.

You can't just drop in a distributor in a dis less system. Have to change the PCM and harness as well.

psst, Talyn:

I was being sarcastic.

Ya that would require an entire rebuild forged this and that, most would havto be custom and some serious boost so it would be a drag car basicly, and that will do you no good on the street or when talking to the smog police, BUT just FYI a stroker, or even some basic upgrades will give more power, and for some reason it is very noticeable in the 4.0s...

[wolfpackjeeper]

I bet a 4.0 would take 3, maybe even 4 200hp shots of nitrous before it was completely unusable...

[Sherman_thetank]

I took me about 1200 for a mostly stock build, and a 200 :shocked:.....wait that would be alot of fun.......:rolleyes:

Just build a prerunner.
