2.7L Turbo or S/C? Bad idea for a commuter?

Yeah, it's always fun to vicariously spend other people's money .

 

Haha!!! Now THAT'S The response I was looking for

 

Well, im in the process of turboing my truck. With around 7 psi I will be making a couple more hp than a 1st gen v6....But you have a 2nd, big jump from the 2nd gen 2.7. Hopefully around 12 psi I can be at or a bit above a 4.0

Only reason I am looking towards a turbo... keep the size of my 1st gen but power without an engine swap

 

I recently went from driving a 1st gen 2.7 in my built 3rd gen 4runner (which I love, but is now my wifes commuter, for reasons...) to an '11 AC with the 4.0. Honestly the truck feels like a rocket compared to my old 2.7. I had no idea what I was missing. I still love that old 4runner and she does just fine scooting around (slowly), but the v6 has almost 100 more hp, and should be just as reliable as my old 4banger has been.

The idea of Forced Induction is something I toyed with on the 2.7 (and came very close to risking my wifes enduring wrath over), but all of the hidden costs are what made me rethink that plan for a daily driver. When the 4runner becomes our 3rd car here in a year or two, hells yes I'm gonna build her a FI engine!

 

You guys are seriously making me consider upgrading to the V6...

 

Long story short is that with good tuning, either a turbo OR a supercharger can be done well, and will make your daily driver perform and drive better. That being said, you will have to pay somebody to do GOOD tuning. A turbo will get you more power if you like to wind the engine out and get into the high rpms, and also it MAY provide a slight boost in efficiency if it is tuned right. A supercharger, on the other hand, is always on so from a dig you will have more torque, and will likely have a much better driving experience if you DONT like to rev out during daily driving. Supercharger comes on hard from a dig but loses effectiveness the more you rev the engine out, where a turbo is the opposite. Turbo will have to spin up first, especially on a 4 banger, so you will have some appreciable lag until that happens. Depending on the size of turbo you choose that could be less lag, or could be more lag. You trade the off the line performance for making more overall power in the top end. If you know how to drive it, a turbo is going to be a little 'faster' than a supercharger, but theres a good chance that fact alone means a supercharger would be more reliable in the long run, since you dont have to wind out to get that power, which means less strain on the engine to make power, and the fact that it runs out of steam at high RPM means that it wont overstrain the engine on the top end the way a turbo can

 

Thank you for the breakdown of the two! I'm only just now learning about the differences between the two, and this was very helpful.

 

No problem man! You probably would also want to know that all told, youre likely talking about the price difference between your 4 banger and a V6 to get the 4 banger force-inducted and tuned right, no matter which route you take. That being said, you would have about the same power as a V6, with better fuel mileage, and probably even more fun to drive. Its a decent option. In the long run, you might be better off running the 4 banger till she dies and then finding a wrecked camaro, corvette, SUV, etc that has an LS and do a full LS motor and T56 tranny swap. Youd probably be talking the same sort of price range. Id expect 7-7500 between parts, labor, and tuning on a forced induction build where an LS swap will only run you a couple Gs more for WAY more power and much more usable power. Youd also likely see a big jump in MPGs during daily driving since that motor wouldnt have to do shit to get your truck moving normally haha

 

You guys know the URD kit is bolt on and comes with an Ecu plugin with the tune pre programmed right

 

Didn't know they made it THAT easy, but thats awesome. They should work on one for the third gens now

 

Just resentley talk to LCE they are working on affordable low boost Supercharger and bigger valves and port and polish heads and pistons on the 2.7 TR FE 4 cly motors coming out spring 2019!! Stay tune

 

DOA will be also offering bigger valves and cams and awesome port work on the heads and bigger pistons for 2TR FE 2.7 4cly Taco motors this spring summer time 2019.

 

I am in the same boat I also got a cummute 2.7 TR FE truck I am building don’t know about the Superchager right away but will be doing bigger valves port work and maybe a cam to get me close to 200hp!! All ready got all the bolt on stuff truck is ok but looking for spank power.

 

Do you know if they said it'll be a roots or centrifugal s/c? hopefully roots

 

Does he have any 4.0s?

 

For RJ Biii not shure about LCE up coming Supcharger design only thing they mention it wil be a Eaton supercharger low boost plug and play and no need for piggy back ECU the current ECU will adjust it self like the old low boost 2.7 RZ motors.

 

ECU is only good til about 8psi. Mostly because you run out of fueling. Once you add the larger injectors/pump, the stock ECU can't trim enough fuel out at idle to not throw a CEL.

 

Cold air intake, headers & exhaust, and pedal commander. Has done the trick for me, in the same boat of love my 4 cylinder, but wanting just a little extra power, at first was tunnel vision on the URD supercharger, but with the mods I've done, all in about $1200 total for intake,headers,exhaust and pedal commander, it's a satisfactory improvement, still not a racecar by any means, but gets up and goes now, when " I " want it to!! basically eliminated the sluggishness on a much cheaper level than the supercharger. Although I still want the supercharger,maybe one day when I hit the lotto!

 

curious, it wouldnt be too hard to add a 3psi turbo on the 2.7 right? I think you can find an exhaust manifold from another toyota from japan. the rest would be pretty straight forward. no tuning because its only 3 psi?
