mines an 89 renix. either way if it does interfer with the smog i will still run one i just need to know if i should keep the stock one on the shelf or not.
What does something like this do to gas milage? Good mod for a DD?
Bored TB from strokedjeep.com here. Probably one of the best 90$ you will spend on your XJ. Only had mine installed for about a month, throttle response is better and seen a slight increase in mileage. I am also running some of the Ford Orange top 19lb injectors.
When you install make sure you adjust your TPS.
I put my stock one on a lathe and it's at 60mm and it works well with the K&N FIPK
Stock is only 59mm tapered down to 55. So if you just did the bottom portion your not getting a full 60 out of it. I'm having mine redone by a friend with a lathe, we're bringing it out to 62 and making the new throttle plate as well should be pretty sweet and a lot cheaper than the $90 the Jeepstrokers guy is charging. He must be making a killing of these and that's cheap, a lot of places are charging at least double that for one.That does help.
But, when you get one from www.stroked jeep.com , it comes with a 60mm butterfly as it is bored all the way through. 60mm flows alot more air than 52mm.
