let me start off by saying i have read the tech write ups, as well as several of the topics in the 2.9l section before coming to the conclusion that a new thread was warranted. i feel that there is contradicting information that has been given, making my decision on how to gain more power difficult. i also feel that my situation is different than the other guys who asked "How do i get more power."
Ok, my situation. My 88 B2 is the rig i am looking to make more powerful. the only thing i use the rig for is mud racing, so i relay don't care what will happen to my MPG's, as a result of adding power. i dont care if it idles ruff, or how "smooth" the power is, or if it is road friendly. i am currently running the 2.9l, all stock except a K&N cone. the FM146 5 speed trans, and 4.56 gears in my axles. so i am looking at adding some power. in the "Kunz Korner" in the tech library's it seems to suggest that there are things that can be done to the 2.9l to see significant power gains. (yes i understand significant, is a relative term.) mainly by working with the intake, throttle body, and using low temp thermostat. in my case i would, if i go this rout use the 160. Then i go into the 2.9l topics hear in the forums, and any time a guy asks about adding power everyone says "you cant get more power out of a 2.9, do a 4.0 swap." iv seen guys ask about the Tom Morana stuff, and get the same answer, but then other guys will say that anything Tom Morana makes is top notch, and that he is a reputable builder. So if he is a reputable builder, and he says that one of his parts adds 20hp, shouldn't one assume it will. i realize a lot of company's will claim there $200 computer chip will add 20 hp, and i know that is BS. but again when a reputable builder makes that claim about there $800 part, it seems a lot more believable. Now as for doing a 4.0 swap as an option, please excuse my ignorance to the subject. it seems to be relatively easy, except the wiring, and the need for the dash out of the donor vehicle. i see that Morana also offers a conversion intake manifold, to switch the 4.0 from fuel injected to a carb'd engine. would this eliminate the need for all this wiring and new dash? Ok i think that about covers my question, sorry i did not know which topic to put this thread in sense it deals with more than one type of 6 cyl motor.
