turbocharging a 4 litre

Does any company make a turbocharger setup for the 4 litre V6? Or is the supercharger made by toyota for this engine the preferred way to go to get more from the engine?

 

TRD supercharger is around 2g's and it will get a lot out of it
turbo chargers work with a turbine which generates more air
to your engine more air to your engine mean there has to be
more fuel and superchargers work as another belt to your truck
not just will your engine last long but you wont be forcing it

 

Sorry if I sound blunt, but you have absolutely no idea what you're talking about do you...

Superchargers are actually more parasitic to engines than turbos. Both push "more air"...

 

no he doesn't

 

I wonder how much that hurt pulling it from his ass?

 

Good points. I think it boils down to what a person really needs from their truck. I was thinking about a turbocharger setup to get more low-end torque for trailer towing since the 4 litre is underpowered for this truck (IMHO). Others may not agree with that. Then one has to consider the whole truck and remember the weak brakes that should be dealt with if towing at rated capacity. Now if not towing anything or only really light loads, all this would not matter.

I think I will just leave my truck stock. It is running great the way it is. If I really want to tow heavy I will obviously need to go to a bigger truck with the wheelbase, brakes, and engine power to do that safely. I just don't think the tacoma has the brakes to safely tow at or near the rated 6500 lbs. The taco is good for general running around, general offroad trail use (IFS limitations) and light towing use. Nothing wrong with that, the truck is a light-duty vehicle and as long as that is known up-front all is OK. Probably could be said that if many thousands of dollars need to be spent to structurally change the truck to perform as desired, then you don't have the right truck to start with and the money should be spent to trade for the truck that is actually capable of doing what is needed. This would include solid axle swaps, superchargers, complete brake redo, etc. Reason is that the money spent doing these things will never be recouped on vehicle sale so it just does not make sense.

 

Agreed. Words of wisdom there.

 

I wouldn't think a turbo would increase low end torque anyway, turbos don't typically produce power down low, they have to wind up and work at higher revs. Of course it depends on turbo size and design but I can't imagine turbocharging would be well suited to the Tacoma unless you're talking a 2wd pure street model.

commtrd, you make good points about not trying to make the truck something it's not, just fine tune what it is and you'll be happy with it. I enjoy my mods but just went with TRD bolt on stuff (short shift, intake and exhaust) and basic suspension upgrades. I tow a 6x10 enclosed motorcycle trailer easily, could certainly pull a boat or larger trailer. I offroad mine occasionally, very competent through muddy roads and fields. It's a great all around truck other than less than stellar fuel economy, but that's no different than any other 4x4 out there.

 

My truck is really a nice truck and works great for what I am using it for. I may need to tow a larger travel trailer (would like a 25' fifth wheel) and this access cab truck clearly will not do that. I would like to keep this truck AND get a 3/4 or 1 ton diesel to tow with...not sure the boss [wife] is going to be OK with that though. My taco does tow my 19' flats fishing boat OK it's not a ball of fire but it does it. The brakes suck I really wish I could do something about that. The truck goes through deep sand like nobody's business so great for going to the beach. I love this truck it just has some fundamental issues that should have been done right from the factory especially for what the truck cost. For general use it is just fine...when starting to push it the truck starts to show its limitations.

 

Depends on the size of the turbo, fueling and engine load. Beign a diesel guy I prefer turbo's

 

Actually the more fuel you add to a diesel the hotter it gets, whereas it is the opposite with a gas application. This is why you can slap a big turbo on a diesel that flows a lot without necessarily needing fuel upgrades. On a gas engine the more air you have the hotter it runs and this is why you need those fuel upgrades with adding a turbo or S/C

 

I think some one on here has a turbo kit forsale on craigs in FortWorth. I think it's everything except the injectors and programming.

 

i wish!!!!!!!!!!!!

 

Skip the turbo and S/C and just trade it for a Tundra or a vehicle with the power you need. IMHO I think both they hurt your resale and you waste your money. I would never buy a vehicle that has aftermarket engine modifications. I am just saying.

 

If you need more low end torque you'd need a supercharger, not a turbo. Turbo's turbines are powered by exhaust, which only start spooling enough to boost after you get into the higher RPM band (especially a single larger turbo, smaller twins can spool faster). However for towing on a petrol engine... a supercharger is really the only solution I'd recommend. It will run cooler and be more robust, you can shut it off like normal instead of waiting for a turbo cool down time (remember turbo's get up to around 14,000F).

Also, if the TRD supercharger isn't your cup of tea, URD offers a great package in Mark I, II, and III packages. Mark III with supporting mods (including a valve body upgrade for the auto transmissions) will throw down 400hp+.... Gadget's X was running about 420 with it last I checked.

Also note, personally down the line I intend to supercharge mine. (that will be awhile though, $ is a bit tight haha). I couldn't really see running turbo's on here... doesnt' really fit a 4x4 truck's nature imo. It really should have more immediate power on demand instead of waiting for spool, especially in off road or towing situations.

Something else to consider, if you get the TRD Supercharger with stock stuff and let the dealer do the install... your full warranty on the truck is still in effect. Seriously you can't ask for more on that front. the 2009-2010 TRD Supercharger fit kit was just recently released too. Check out trdparts4u.com

 

Upgrade the pads, get stainless brake lines and possibly change the tires. These are a few things I could think of to improve braking performance. Your system may need a flush as well.

 

Yeah if it was 2k i would have one along with everyone else on here.

That STS turbo kit looks like a china made pile of shit.

 

Custom made rear mount.. not the STS. Would be plenty of fun
