i was wondering what would be better a 62mm tb and 62mm tbs or a stage 2 jet chip and the 180 degree thermostat do any of these make a different on mpg and horsepower and torque??? thanks for the help

well first off do u have an exhaust and cold air intake on it yet?

xjhoup

yea

honestly the biggest gain u would see is a header and a 1999 intake manifold u would see probably 40hp and 5 mpg

xjhoup

really any kind of header and do i have to mod anything for the 99 intake manifold to fit does the 99 flow better or something??

i would like header with the pipe that goes to the cat so i dont have to bend any pipe thanks

93xj

um the ones i listed are direct bolt on's u unbolt the one on ur jeep and bolt that one in place... tho the flange that holds the bottom to the pipe that goes to the cat is sometimes a bear to unbolt its not that hard i would give it a 3 out of 6 beer job

one more question will a 96 after market tb and tbs fit on a 99 manifold

93xj

are u asking this because u have one or know of one cheap or are u just curious because u can just order one for the 99 but as for the sizes i am not sure

xjhoup

i can get them for cheap

i consulted a vendor friend of mine and he said u can use the same throttle body from 91-01 so theres ur awnser lol
