Or this for 62mm+! I have heard only great things form strokedjeep.com, but have never used it myself....

 

I will have to look into that once I have money to spend.

 

What HP gains do you get from a bored TB?

 

Minimal if any but a big boost in throttle response. I stomp on it and its there almost immediately no delay.

 

2 things: 1st, My ex-father in law owns a machine shop. So the engine work, with his help cost next to nothing. (Cost of beer which was prolly just as much as the machine work). I would say for 2000 - 2500 bucks you could build an engine that would last forever with good maintenance. 2nd thing, save money for things you simply cannot do yourself. Here is a picture of an intake I made for less than 5 bucks (besides the cost of the filter) Its an exhaust adapter with some pipe for the hose connections.

 

interesting article... Says the 99+ intake manifold lost power on there dyno lol
"Actual Gains: 5hp loss on Trasborg's '98 XJ (Project Mileage Master)

 

That article has been tossed around a lot and there is some write ups about it. With just the intake manifold yes you probably will see a loss. With all the upgrades I've done there is a gain.

Something to ponder on http://www.jeepforum.com/forum/f11/9...d-lie-1122224/

 

I have 703's and a bored t-body. Think ill notice an improvement with the newer intake manifold? This thing is a dog.
