i had a 1995 V8 Grand Cherokee years ago and still miss the truck. Not a single problem with starting the engine (even in -22F/-30C weather), never stalled, not a single serious problem while we had it for 4 years and used it 7 days a week.
That time i was living and studying in US though and gas prices were 2-3 times lower than in Northern Europe where i'm living at the moment.
So lately i've been thinking about getting another V8 ZJ and perform a auto to manual conversion and build the engine abit (and driveline, suspension and the rest) to have a nice sleeper to hunt down those slow diesel X5-s and Land Cruisers and even fast looking but 2.5turbodiesel European sedans
Don't get me wrong, we are having also a 330hp BMW in a family but love the idea of a oldlookin American ultimate sleeper you can use yeararound and on every surface.
I prefer manual tranny over auto and also manual should give better fuel economy when using it as a daily driver i quess (lot of highway driving).
Told my gf about the budget i'm planning to spend in coming summer and she gave me a green light, so this post is kinda the next step
I have done a lot research on building the engine, so there are no more questions about it now, only Jeep related stuff, hope you guys can help.
Engines, gearing and manual transmission regarding gas mleage:
and got engine rpm-s like those for 55mph:
Tranny: Gear: RPM: Speed: R&P ratio:
46RE 4th - 1596rpm - 55mph - 3.54 gears
t56 6th - 1318rpm - 55mph - 3.54 gears
t56 6th - 1389rpm - 55mph - 3.73 gears
t56 6th - 1527rpm - 55mph - 4.10 gears
So there would be significant drop in rpm-s using t56 or similar 6speed unit over auto.
Got 20+ on highway with 46RE and 5.2 V8 but can you guys give any estimates regarding those calculated rpm-s and 300hp 318, 350hp 360 and 350+hp 390 stroker engines? So i could choose which route to take after seeing some sobering estimates on mpg, as i said fuel here is expensive :S and would like to use the truck pretty often on highway.
The other question i had was about transfer cases, should i prefer NV249 QuadraTrac or NV242 SelecTrac for that project? Any pros and cons? And what would be good overall gearing for good off the line and not too bad high end?
Whoa, thats kinda it for now, hope you can give some advice on that topic.
Thans a lot.
