General Jeep Questions
I'm back in the market for my 3rd Jeep. I've owned an '88 YJ 6cyl and an '85
CJ 4cyl. The CJ was crap (bad engine, among other things) and the YJ wasn't too bad except for that dreaded carb. Anywho, I'd like to spend up to around $6500 CDN for one but I'd like to do it right this time. Hence, I have a few questions: 1. I know the 87 to 90 carbs are crap on the YJ's. What are some advantages and disadvantages to the following: - 87-90 with a swapped in Weber - 91-95 with fuel injection - pre 87 CJ ...do I keep it stock? rip out computer? swap in something? 2. I hear a lot of bad about the Puegot trannies in the YJ line. Is this just for the 87-90 ones or does it continue up to 95? What about the CJ trannies? I've heard the 3speed autos are good for off-roading. For some reason I'm hesitant to buy an auto ...is this unjustified? 3. I bought one 4cyl 2.5L and everyone told me afterwards that it's a mistake to buy any 4cyl Jeeps. I've noticed anything with a 4 is pretty cheap compared to a 6 or 8. Is this because the 4 doesn't have enough power for a modified Jeep? What engines are the best? 4.0L hi output, 4.2L, old CJ 6cyl, CJ 304 V8? 4. Are fiberglass tubs good for offroad, especially strength-wise? I live in the salt belt of Canada and so anything with a metal body rusts to hell but I've heard some horror stories of the glass tubs offroad. 5. Are there any particular lift kits/body kits or other mods that I should watch out for? Any brand names or styles of doing them that will cause problems? 6. Anything else? Thanks!!! |

(it is based off the old 232/258 block like 4.0 is) I have one in a 2000 Cherokee that I bought new that wife dirves to work and such and it has over 80K miles on it now and it has been very reliable and never failed to start and run well be it 20 below and near 100 out. It has stock sized tires and stock 4.10 gears and it does fine. It does not have the power to cruise 80 all day on hills but at lower speed and around twon the engine is very torquey and pulls very well for its size especail at lower RPM's. Where these engine "fail" as poor power plants off road is that people lift them up and put big tires on them and never bother to regear the axles. (they "think" they can tune fix this with exhaust and intake but they cannot) If you had a Jeep with 35's and a 2.5 with some 4.88 or 5.13 gears it it, it would surprize you how well it would do off road. It would not be a good high speed highway cruiser (not because of RPM from gears but because of increased drag from lift and tires vs power avaible) but it would be a fine off road machine that would be lighter up front, easier to keep cool and use less fuel off road extending the "fun time". I have been off roading and driving 4x4 for over 35 years now and some on the most fun vehcile I have had off road were smaller ones that were lighter and geared deep. One exception to this was back in the later 70's I had a friend in NC that had a old 52 Dodge miltary truck that looked like a jeep on steriods. It was 100% original complete and in very fine order. It had a flat head 6 banger that was good for about 70 HP or 80 HP so in this 3 ton "jeep" with a engine driven winch on front of it. It hand a total of 8 speeds did not care to go much over 40 MPH or so but it was a TANK off road (max speed in first low was just a few MPH) and would go anywhere you pointed it and if the hill was too steep to drive up, you could use engine driven winch to pull you up with no worries of winch overheating. I had a change to buy that thing back then and I regret not doing it and storing it and bringing it out to play with from time to time. ----------------- TheSnoMan.com |

General Jeep Questions
Hmm ok, so as long as I change the gears to match any mods I do, then this
engine is good enough? I will only be using it as a "for fun" daily driver in the summer just for light inner-city cruising around with the top half off. The rest of the time it'll be used for mud offroading - nothing TOO serious but I do need some power to get out of the thicker stuff. Are there any differences between the 4's of the CJ/YJ/TJ line? The 4cyl TJ's from '97 to '99 seem to go pretty cheap relatively speaking. I've seen some around 100 to 120km for 8-9000.

The carb from 1982 to 90 is pretty much the same one. It 'is' a Weber-Carter BBD according to the cast on the float bowl. I don't find 'any' trouble at all making any of these year's carbs just purr. I can go vertical up sand pit walls and hold 400 rpm as I chug to the top, so can any others I have tuned. We also get over 20 mpg highway 'and' pass Canadian emissions. The big trick is to follow the tune up schedule. The carb is supposed to get a kit every time the engine gets new or refreshed spark plugs. No one does this then they can't understand why a 20 year old carb runs like crap. For all these years, it is easy to get rid of the computer which you have to do if you swap the carb out anyway or it will run like a pig and drink gas. That is the 'Nutter' bypass. > > 2.

The clutch has been sometimes leaking fluid out for years and sometime not, but it still goes fine. The CJ's had solid trannys, mine has the Borg Warner T5. > > 3.

Yup, a 4 is lacking for modified vehicles if the gears aren't changed, other than that I have wheeled with a bunch of 4 bangers and didn't notice it at all. > > 4.

I live in > the salt belt of Canada and so anything with a metal body rusts to hell but > I've heard some horror stories of the glass tubs offroad. Well, I have some some serious off roading here in Canada including having the rubber side up a couple times and my 'glass body is doing pretty good. I did manage to crack the glued seam where the firewall meets the floor in one roll over and crack the door post in an argument with a tree. Easily fixed. I got a sweet body made from a gent near Kingston Ontario. Sucker has diamond plate in the firewall and a 1" waterproof plywood core in the floorboards sandwiched between the double shell. I got the one piece front flip clip for it. Everything fit on perfect too including the hard doors and top and I fit my 'Laredo' chrome grill insert into the front clip no problem. > > 5.

I had a local truck spring shop order in a new set of CJ springs. The took the pack apart and arched them for a 2.5" lift while replacing the top free leaf with a pre-arched 'keeper' spring. The took my old front spring pack apart, arched that with another keeper spring to match the new backs. This was in 2000 and it had held perfectly. > > 6. Anything else? > Good luck!

I don't need any *crazy* mods but I'd like to put a 2.5" skyjacker spring lift and throw some 33" BFG MT's on. Should I change the gears for this? Is this a bad lift idea? Anything you'd recommend? |

I can still use 5th, but it costs gas, about 5 mpg better without it. Off road we have low range so never have issues. As mentioned, 'I' had a big truck spring shop do my lift.

In other news, I had a transmission fluid leak on the '93 GC, it was up front where the transmission cooler lines connect to the transmission cooler. I took it to a shop that I trust and they tightened the hose clamps so I'm guilty of the same failure to contribute to the economy, I should have taken it to the dealer who would have replaced the transmission, radiator, cooler and then sold me a 2007 GC Limited. Just think, if I'd done the right thing, I'd have a brand new GC with a 30 year mortgage..... you can't imagine how guilty I feel! <GD&R> -- XS11E, Killing all posts from Google Groups The Usenet Improvement Project: http://blinkynet.net/comp/uip5.html |

He thinks 3.31 gear with a 33's is a GREAT combo and he does not even know how to change a diff cover gasket let along a gear set or what it can do. DO NOT take his advise and ham string your on and off road performance. People like Mike are why some complain about needing bigger motors because they fail to understand the importance of gear ratio. I will not even get into the effect the tall gears have on wheel traction due to torque inpout into a tall ratio with bi tires because this completely escapes Mike because he beilieve ina magic force that keep both wheel planted the same regardless of drive shaft input torque. He does not even like know what Newton Law is let alone how it applies here >Off road we have low range so never have issues. Another stupid answer, 33's without regear reducing power about 15 to 20% in a ALL gears and ranges if you do not regear. > >As mentioned, 'I' had a big truck spring shop do my lift.

YOue may call this a attack but when some one is looking for advise starting out they do not need your "foorget 5th gear and use low range" as the right way to do things. You give Jeep owners a bad name. ----------------- TheSnoMan.com |

You are a brain dead idiot which you have proven over and over and over. You have also proven beyond any reasonable doubt that you are totally insane and give out advise that will kill people. Yes, I compromise unneeded things like lower gears due to funds and use my gears. I still get 11L/100km or 23 mpg using only 4th as a top gear foole! And I can think of 'much' better ways to blow 2 grand than for unneeded gears. No I cannot fix my Jeep much anymore because I got smashed up in a car accident. Yes I farm out 'specialized' work like gear setups and springs to 'professionals' with the right tools 'even when I could work on them'. Now as to how many Jeep engines I have helped folks from this newsgroup rebuild in a snowbank in the driveway, well... They 'all' are still on the road going strong... No I am 'not' stupid enough to use a shop that has platinum tools or sells gold plated parts, which you seem to advocate. Yes, I 'use' my shift into 4 high at any legal speed option that my Jeep came with in the winter rather than stop in the middle of a highway in a snowstorm to shift gears like 'YOU' advocate. (That proves beyond any reasonable doubt that you are totally insane with no regard to anyone's safety!) Yes I goose my tires a little in reverse to unwind the drivetrain if it binds up rather that stopping on the highway in a storm to jack up a tire and let the stress off 'easy' as you advocate and actually suckered someone into. (more Deadly advise) 'My' Jeep can take that with no problems, I don't drive wrecked 'snoplows' that can't spin a tire without exploding like 'you' have stated yours will do. Now once again screw off! Mike 86/00 CJ7 Laredo, 33x9.5 BFG Muds, 'glass nose to tail in '00 88 Cherokee 235 BFG AT's - Gone to the rust pile...
