Finally read about our engines....

clearly you need to remove your head from your rectum. just because it's a pushrod engine doesnt mean it's not high tech. Pushrod motors make torque quicker, and flatter, than overhead cam engines. The whole aftermarket world is turned on its head the last few years because the LS motor is *so* good, they are putting it in all kinds of crazy shit - like miatas and S2000s. It's a simple motor that's built to perfection. It's light, makes a shit ton of HP, has a torque curve that is unreal, and it's cheap. The Z28 *camaro* ...yes... a camaro.... is beating the pants off the bmw M4 ...that has all sorts of high tech gadgets and overhead cams and turbos and bells and whistles. Not just 1/4 mile. or 0-60. In slalom, road courses, etc etc etc etc. It costs half as much *and* the interior is nicer.

I'm by no means a chevy guy - but the LS motor is a work of art - it's cheap, its powerful, it's light, it's compact and you can put it anywhere. Oh....and it runs *forever*. I work in the marine world. I routinely see these latest generation GM blocks running into diesel territory of lifespan and fuel efficiency. 8000+ hours of hard marine usage and still going.

Just because it has pushrods doesnt mean it's crap. It just means theyve had 80 years to perfect it.

 

Sorry did you Wiki something and consider yourself an expert? I'm sure this 10 minutes of research is well valued in comparison to the thousands of hours spent engineering this power train combo. Thanks for tip.

I'm going to go hang myself now since I made such a big mistake.

Edit: and I also hate how I average 16 mpg towing 3500 lbs. Especially since my new 12' Taco averaged 17 mpg with nothing more than a big gulp riding shot gun. Terrible - just terrible

 

It's actually powerful for its size. Lots of tech in the motor which increased efficiency. Kind of the best of both world in a sense. Of course you'll never make everyone happy

 

Are you talking to me? Listen, punk, scroll back and show me where I said I was an expert? Did I just not step forward and volunteer that i did not know exactly what I'm talking about and only had a simple point to make?

Are u the kind of doggie that barks through the screen door all day?

 

You scroll back and look at every one of the 300+ messages I've written and you'll see not one is as blaitenly sarcastic and asshole - ish as the one you recieved for your highly misguided point.
I've seen a lot of stupid shit on here but starting off a thread with wiki is just plain neive bro. Don't take it the wrong way

 

How could I have forgotten the Supra?! That thing is a fucking beast even when stock

 

Don't take being called naive the wrong way? Look, we all know what wiki is. I was trying to make things simple. What i linked to is the list of modern cars using the atkinson technology... which happened to be on wiki. And which, still, is true. Whether it's on wiki or not (which often IS wrong, I agree).

But deconstructing this engine was not my intention. I work for Hollywood. I'm no mechanical engineer. I know my place in the world.

But I stand by my super simple point. Folks I've seen on this forum - that are looking for more power in their 3.5 V6 Tacoma engines - are barking up the wrong tree. They're talking about F150s and Tundras and V8s galore etc. They want everything in their little toy truck... but that's not what this truck is. Is an efficient little guy with - yes - impressive hp for its size - but still not engineered to be a full size pickup. They're not gonna get full size power.

Such a simple point. And such simple little links I put up. I'm sorry they hurt your head.

 

The motor is a great compromise of power and efficiency. We need to note: this truck is heavy. Imagine this motor in a 1987 pickup. It would flat out fly and tow the moon.

 

Idk if it depends on speed but I've offroad a few times where I had to hold the brakes and give it gas at the same time to climb a pretty aggressive rock hill, forward and in reverse going up hill.

 

I'm sure speed is rolled into the equation

 

You don't know turbo. I wouldn't touch one with a 9 feet pole

 

The GM LSx series engines come in all kinds of flavors and powers up to well over 600 HP in production cars. They are powerful and efficient. Almost everyone else builds a OHC engine these days and nobody is really trumping the LSx series engine in capability. Additionally, the pushrod engine is more compact as you don't have to have giant cylinder heads to mount all the cam gear on.

The GM LSx is a seriously good engine.

Yup. The original GM small block was essentially built and used for about 50 years. It was a great little engine with lots of capability and only had some relatively minor changes in it's lifespan. The LSx was a redesign that greatly improved on the old small block Chevrolet.

 

Honestly, I think the 3.5 and the auto are really quite fine for the application. It makes plenty of power for a mid sized pickup. I'd love an LSx in one, but I'm never going to bother to make it happen because what's in my truck is really just fine.

 

Oh, I say no to a turbo. I think oversized hair dryers are great for some applications, I don't really want one for long term reliability purposes. They end up adding extra heat in the engine bay; since they are exhaust components, they rust up making work under the hood harder; more junk under the hood; expensive to fix; can really break stuff when they go bad.... I want a truck I can no problem put 200,000 miles on with minimal maintenance.... Turbos just make that harder to do.

Turbos are fine for hot rods..... not for a utility vehicle like a truck.

Yes, they put them on diesels..... because diesels need them to make horse power. It gets really expensive when they break. If I'm on gas, no turbo.

 

.
...^^^... Not a "turbo guy" here for a truck either ... maybe I am too old school.
.

 

NA motor, 6MT, 4.3 gears, it's why some of us are here in the first place. buy one while you can if you hate AT's and turbos, they may not be long for this world.

 

Oh, I like turbos.... they are pretty awesome... just not for this application.

 

Not saying I dont like that cheap power. But I have enough dealing with a rebuilt every 80K miles or oil will leak and burn out of every fucking pores, and then the HPFP seized twice. I had three cars with German KO4 crap. No thanks. Natural aspirated from here on in.

Yeah and like everyone else said, Turbo lag. you can go smaller turbo for quick spooling but how much air can that push?

 

I think that a nice 4.6 liter v-8 from the Tundra would work. Moved my 2010 Tundra just fine, getting 18.5 mpgs in thst big truck, imagine it would do well in the Tacoma.

 

Agree, also dealt with KO4's and seized HPFPs. As far as turbo lag, some European cars use twin scroll turbos or combine small superchargers with a turbo to be rid of that problem, but to me that's just more stuff to go wrong.
