DirtyComanche Posted August 16, 2006 Share Posted August 16, 2006 CD players are an amazing mod. It cured my whiney peugeot, rough 4.0 and the rattling of all the loose parts trying to fall off. Link to comment Share on other sites More sharing options...

ORCA Posted August 17, 2006 Share Posted August 17, 2006 CD players are an amazing mod. It cured my whiney peugeot, rough 4.0 and the rattling of all the loose parts trying to fall off. Playing the right music (SLAYER?) it'll add HP too. Link to comment Share on other sites More sharing options...

mjeff87 Posted August 17, 2006 Share Posted August 17, 2006 anywhere between 18-20 mpg in my 2.5, depending on which way the wind is blowing :D 4.10's turning 235/75's, and 171K miles Stepping up to 31's soon, and regearing to 4.56's...hopefully it'll be a wash mileage-wise, although I don't see me commuting in it much at that point.

Pete M Posted August 17, 2006 Share Posted August 17, 2006 If you're spending all that money on regearing, I highly recommend 4.88s. :D Your 2.5 will thank you. Link to comment Share on other sites More sharing options...
mjeff87 Posted August 17, 2006 Share Posted August 17, 2006 Yeah, I know they'd be better, but I'm doing this on the cheap :D I scored a D30 with stock 4.56's in it out of the 'yard (from a 2.5/AW4 XJ) for $80....it's been sitting in the garage in PA for almost a year now. I traded 2 XJ D44's for an MJ D44 (3.07, open :cry: )and a brand new set of 4.56's with install kit. All I need is either an open carrier (and drop in a quick loc later) or a detriot now....I can't decide which to do. Add $100 or so for a gear setup, do a disc conversion on the '44 and slap them in. I oughta go full locker now, but funds are kinda lacking at the moment :( Oh, and I want to add an inertia ring when I swap trannies out. ^^^fall project^^^ Jeff Link to comment Share on other sites More sharing options...
JOMJ87 Posted August 17, 2006 Share Posted August 17, 2006 Oh, and I want to add an inertia ring when I swap trannies out. Do these things really help or what. You think someone with resources could make one on the cheap? I haver heard some things about them and its been mostly good and i have thought to do it.

mjeff87 Posted August 17, 2006 Share Posted August 17, 2006 I've never run one, so I can't speak from experience. But a couple of reputable guys over on NAXJA have, and say they really help (and the 2.5 needs all the help it can get). The way they work is that they add rotational mass to the end of the crank to keep it spinning between ignition (power) pulses..which on a 4 cyl is only 1 every 90 degrees. They don't do so much for top end, rather it keeps the engine running when you lug it down to low rpm's, which is where I have problems. If I keep the wheelspeed/rpm's up either by pedal or using 4LO it does fine, but if I'm in sticky mud or stall on a hill in 4HI I have problems :headpop: There's times I'm in 4LO when I shouldn't have to be, and I don't like crazy wheelspin :driving: I figure between it and deeper gears I can avoid both situations (crosses fingers) I feel it's a worthwhile mod for what it costs if you wheel a 2.5 I'll do a writeup with pics and post in the projects forum when the time comes.

feerocknok Posted August 17, 2006 Share Posted August 17, 2006 I'd be weary of a 2.5 on 4.88s and 31s if 31s'd be as big as one would go. Seems like highway speeds would be a lost memory. Link to comment Share on other sites More sharing options...
Pete M Posted August 17, 2006 Share Posted August 17, 2006 Should be less than 200 rpm difference on the freeway. Link to comment Share on other sites More sharing options...
