My 3.0 is at 275,000, been god knows where and back, and is going strong.
I thought that you had a rod knock. <img src="/forums/images/graemlins/bird.gif" alt="" />
Get a larger motor, spread out the stress, enjoy longer life, enjoy better performance.
So using this rational he should get the largest displacement motor on his list, right? That definitely would not be the 3.0L V6. America builds four cylinder motors that big. <img src="/forums/images/graemlins/notooth.gif" alt="" />
Now that I think of it, I really can't think of one good reason to sink dough into that little motor. Oh well, your truck.
My motor only made 7 less ft-lbs of torque than your motor when stock and the peak was 600 RPM lower. And my 4 cylinder motor is lighter, easier to work on (or add dual batteries, on board air, etc under the hood), and comes backed with a gear driven transfer case that I just added 5:1 gears to. <img src="/forums/images/graemlins/smile.gif" alt="" />
Plus I have to wonder why there is virtually NO aftermarket support for the 3VZE if it is such a gem and there are so many of them out there. <img src="/forums/images/graemlins/confused.gif" alt="" />
I seem to have a rod knock... she still seems to run really good despite! Actually, she's hauling butt right now 'cause the truck is so darn light. <img src="/forums/images/graemlins/smile.gif" alt="" />
Harry, come awwwwnn! A bigger motor does not mean THE biggest motor, I said I'd personally stay with Toyota just because. But A bigger motor will solve the problem which really boils down to the 2.4 being too small for the truck.
I'm confused on your specs, last time someone posted torque Vs RPM curvers here, the 3.0, being an undersquare longer stroke motor, made more torque at lower revs. In fact it has more torque at idle than the 2.4 did at peak. It sure drives like it does.
If the 2.4 is so darn great, you tell me why it ain't under the hood anymore??????? It's for the same reason the 3.0 isn't.. NOT ENOUGH PONIES!!!!!!!!! When you figure the Exporers and Blazers had 4.0 and 4.3 liter engines respectively with their smaller engine optoins in the 3 liter range, Toyota was just too darn slow.
BTW, I do not recommend swapping a 3.0, not enough aftermarket support or bang for the buck. I recommend either the 3.4 or the 2.7, depending on what you want out of the truck.
Here's some food for your 4 cylinder thoughts. Toys of old are from Japan..duh.. .which does not have miles and miles of autobahn style open roads. It is a small densely packed island where only the privileged few own cars and speeds are kept down. The market our trucks were sold into was at the time one where the national speed limit was 55mph. Now in Cali it's 65-70 and average speeds in the 65 areas are 75mph, 80+ in the 70mph zones. The 3.0 can handle that, though it does work, the 2.4 is swamped in a stampeed that once moved a LOT slower.
Anyway, I don't care what you all really do, as I said it's your trucks, but my advice is to upgrade to a larger newer motor. I think it would be money better spent.
Frank.
