Hp help

I'm new to tweaking juice out of my vehicle. I just bought a 01 tj and would like to get as much performance out of it as I can without major mods. I just bought a throttle body spacer and will be looking into the k&n fipk and possibly borla headers & catback system. Any comments or suggestions will be appreciated.

I just installed the Borla Headers and I love them. I got much better response on the pedle as well as a better sound. What's a throttle body spacer? Did it do you any good?

evilpsych - sure they have throttle bodies on the TJ's. thats why your gas pedal works i personally wouldnt buy one until someone handed me a dyno sheet showing hard evidence, but thats only my opinion

on performance - since you have modified your intake and exhaust, how about your ignition? while you arent going to see any drastic performance gains, hotter spark to you plugs allows better combustion (a big part of getting this to work is your plug gaps so check into this if you go that route).

as far as the supercharger goes, i would see that as a waste of money. for that price you could easily build a naturally aspirated small block chevy to produce more horsepower. not that the 4 liter is a bad motor, it is an excellent motor with a broad flat torque curve. it just seems like some time put into headwork, quality pistons,a cam, and maybe a stoker crank could blow that supercharged motor away. Not to mention even the best supercharger suffers from large amounts of frictional loss. A correctly set up turbo system would be much more efficient, reliable, while producing the same results. Thats just my 2 cents. Good Luck

I agree with my new best friend Bill there. If youwant that much power, a nicely done small block would make that thing haul major booty, and nice torue for anything u could dish out. And a turbo would give u sweet smooth bursts of acceleration. Don't go too big on the turbo or u may not have too much power when needing to rev real real low.

I didn't get a chance to put the throttle body spacer on yet. Hopefully this weekend will be nice enough to work on it. I know it won't be a dramatic performance gain but eventually it adds up. Thanks for all the comments.

Hey evil spike, you should go back to smoking white ricks....every fuel system has a throttle body except carbs, where in that case the carb is the "throttle bdoy" a bored throttle body will make a bit of a diff on a post 91 (3hp) pre 91's git 8hp! throttle body spacers space out the plenium to make the mixture of fuel/air better some more mods are: highflow cat, catback exhaust, turbo city intake, better wires/plugs, relocate your iat, get an electric fan, ah eader/downpipe and then the almighty blower, turbo, stroker, and nitrous express kit, however you can also port/polish your head, get a new cam, and get roller rockers

Evil I think you are confusing a throttle body with "throttle body injection" the "TBI" uses injectors in the throttle body. The throttle bodies on the port injection systems mostly just house the butterfly plate(s),and other gizmos to make it rune better,(like the TPS)
