Looks like it has a sequential gearbox, droooool.....

how the hell do you build a 2.9?

probably he mod the crank journals, cut and re weld more high the journals, in that way you geyt more stroke....was going to do that in my 4.0L Jeep to stroke I found one stroker crnk already... :P

Did you use the 258ci crank in your 4liter?

That method might work on a cast crank, but not on a nitride hardened, forged crank. ;)

yup! but there are some variations in the 258CID crank, I got one that has less counterweights than my 4.0L crank and other 258 cranks, compared with the 4.0L heavy crank, this one weights 4 Kg less that the 4.0L, that's a lot of difference.

The stock 258 crnk, the late models, has arround 3.85" or so of stroke, the earlier has a bit more like 3.93" or so...my engine went to 4.6L using Eagle Rods for the 258 cid application too with a nice set of Forged Venolias Pistons in 0.30", with 0.60" goes upt o 4.7L

What do you mean with nitride hardened crank? what is the difference?? :?:

Awesome setup for your Jeep. We were going to build a similar motor to put in my brothers old XJ that was setup for the rocks. (Ford 8.8 rear, ARB air's f/r, 4.56 crawlers, beadlocks with 35" Swamps, custom lift, etc...thing was pretty crazy for a Cherokee!!)

Some forged crankshafts have a nitride-hardening to facilitate high-RPM's. This isn't needed on a motor that doesn't turn over about 6000, or has a very short stroke. This is why the 325e and 325i (M20 and M50) both use cast crankshafts.

Note that S14, S38, and S50 engines use this process on the crank because of their long-stroke, high-rpm characteristics.

I got Factory Dana 44 in the rear, both axles are with ARBs too, 4.11 Ratio, skid plates and all the stuff...very equipment my Jeep, I will post pics before and after my overhualled of it soon...

Didn't know that Stu, thanks for the explanation.. :D

[Stu]

Getting way off topic here.... :D

Diego, I just spotted an enormous 2-door XJ while walking back from class. I went to check it out, had Skyjacker shocks with some sort of tall front springs, but a block lift in the rear-leafs. SS brake lines, a really cool track-bar, and some sort of tubular control arms. 33" BFG M/T's, quick-disconnects on the front swaybar. The rear axle had a sticker that said "3.55"......not enough gear to be turning 33's.

[diegom6]

Mmm, Skyjacker, enormous XJ...sounds like he has 5-6" Suspension Kit, SkyJacker are the best suspension with TerraFlex, if those tubular control arms aren't SkyJacker are probably RUbiconExpress if they are not custom . When you get the chance bring your tollbox and bring me that Regulable Track Bar plz...I need it... :P lol.

3.55" with 33"?? nono, that's almost impossible,I mean what Jeep will move byitself with that combo... maybe inside has a larger gear....

If you didn't see my Jeep Pics before my ROll Over is here..you can see the crank and piston/rods comparing in the 2 page, and many pics in the 4th page.

BTW...do you know how can I recover my ID and Password, sent many times mails to Cardomain and didn't get a reply never..??? :?

Dammit, stop it with all the jeep talk.

You're gonna make me go and buy another one.

We went mudbogging sunday and the driver who rambled the hardest was my friend in a bone stock wrangler :P

[YAN-3]

sickness

dude i can only imagine what it feels like when u mash the throttle.. ohhhhhhhhhhhhh :shock:

[grapedrink]

i love it how everyone wants a short shiffter and yet you look at every race car and they are no where near short. more like a nice sex toy to shift around ;0

[Stu]

Killer Jeep Diego.

Sweet pics too. 8)


Yea, the guy must have had a hell of a time turning the 33's with stock gears!!!

[shahe]

HAHAHAHHAHA, you tool when they say SSK they mean the distance that you must move the shifter to get into gear. plus, this car has a siquential box, so the stick never moves anywhere except up and down, and the only reason racecars have such tall shifters is so you dont have to move your hand tooo far from the steering wheel, but the actually shifting distance is short...
