i have 160k on mine, runs like a champ. It's all in the care the 3.5 would be a task because it's DOHC and if you decided to go 3.5 SOHC you'd have to figure out a timing belt to use because of the raised deck height. I'm not aware of any 3.5 SOHC engines.. but i could be mistaken.

im not sure what i will do....is there much to putting a 3.5L in where i have a 3.0.......and just for the asking how much would it cost me to get a new motor or trans. i got a lot of miles on mine and with my luck u never kmow when i might need a new one. You'd also have to include an ECU and the full wiring harness. Best bet is to buy a trashed doner rig and swap everything over. Also I believe the 3.5L uses the larger 9+" rear diff.

i would go to the junk yard but then again i would rather spend more and get a new motor. where is a good place to get a crate motor in the 3.0 and get a good deal?

Probably the only place you'll find a crate motor for a mitsu is.... Mitsu. Good deal?? These aren't American cars so unlikely you'll find a good deal anywhere. Possibility is greater that you'd have better luck locating and having tea with the Loch Ness Monster than finding a "good" deal on a crate mitsu motor. Also, it will probably be cheaper to find a decent used motor and have it properly rebuilt by a qualified engine builder.

I would reccomend getting a good used short block, throwing in some higher compression pistons and going to town. Its the same bottom end as the nonturbo 3000GT's and stealths so high compression pistons are very readily available. Toss in a FPR and some 93 octane and it should be good to go on some 11:1 pistons! (im doing 10:1 on stock fuel system with 93octane)

I covered this once in my SASing an MS thread... The 3.0 Liter MSs have a 9 inch, 28 Spline rear axle and the 3.5s have a 9.5 Inch, 31 Spline rear axle. The front IFS's are the same for both. ARB is what I used to get this info. They ,ake a locker for the 9 inch, but none for the 9.5. I do remember someone saying that the 9.5 comes with 4.90 gears or something. Here is a good thread on it: msport97.proboards6.com/index.cgi?board=off&action=display&n=1&thread=5241

3.5s have a 9.5 Inch, 31 Spline rear axle. The front IFS's are the same for both. ARB is what I used to get this info. They ,ake a locker for the 9 inch, but none for the 9.5. I do remember someone saying that the 9.5 comes with 4.90 gears or something. Yes. With the larger diff for the 3.5L engines do have the "availability" of a 4.90:1 r&p gearset from MMSA but they never came with montero's or sports from the factory so you have to buy them from the dealer and have them installed... but they are available. Unfortunately the 5.29:1 gears aren't available for the larger rear that comes with the 3.5's so that's not an option. Also, assuming the Xcase is the same as the 3.5L Montero's, then you can also get a 3:1 gearset for it from down under. I've done an install of one of these w/ my buddy who has the 94SR and he's had exceptionally desirable results. Of course this was a full sized 94SR Montero, and not a sport. If the drivetrain is the same though there's no reason you couldn't also do it. Oh and you'll need to consider a bigger lift at that point because you'll have enough grunt to pull 37s and you know you'd love to if you could. ;D My friend runs 37" Goodyear MTR's on 15x10 steelies under his SR where he upgraded the gears in both his xcase (3:1) and diff/r&p (4.90:1).

the 3.5 monteros have DOHC heads... the 3.0's have SOHC IIRC, later 3.5's ('97+) came with SOHC heads due to the complexity of the DOHC design. Power came down slightly but not much.

My 2001 Sport with the 3.0L engine has the 4.90 gears stock from the factory.

My 2001 Sport with the 3.0L engine has the 4.90 gears stock from the factory. Are you sure? From what I can find, the only way to get 4.90s is to have the 9.5 Rear axle. That only comes on the 3.5 MSs. The 3.0 come with a 9.0 Inch rear axle with 4.63s. But that is just the research I've done.

that is what is in the 3.5 montero sport (sohc). did u type it backwards? the 3.5 monteros have DOHC heads... the 3.0's have SOHC just wanted to put out there that there r 3.5 sohc cause u said u wern't aware. so no probs with belt routing either clay
