2.7 vs 3.5

You're correct, it's not. ECT changes throttle mapping as well as tranny habits.

 

I've been wondering how much difference the PC would make on a 2.7L DCSB. What size cab do you have?

 

Its long bed access cab. With the PC and the ECT on I can chirp the tires making right turns lol

 

I had the V6 and now the 4 cylinder.

I was shocked how much slower the 4 banger is. But I've gotten used to it and its manageable.

The great thing about the 4 banger is how much cheaper and easier it is to work on.

 

Be even better if toyota went back to the size of the gen1 taco.

 

The newer Ranger is only available in a 4 banger but it's got turbo. It's got considerably more power and better MPG than the 2.7l taco. I wish Toyota would do this.

 

The next-gen Tacoma is rumored to get the 2.4T from the Lexus NX350 with 275 hp — and, more importantly, 317 lb-ft at 1700 RPM — though power might drop slightly if they tune it to run on 87.

I would rather have that than either existing Tacoma engine. Give it a little gas, it spools the turbo and powers up a hill without downshifting.

 

should be interesting. Every small turbo car engine I have ever driven has had a ton of turbo lag. Turbo lag is not good when you try to meter power in an offroading situation. But maybe this one is different and spools better.

 

It's great to go up a hill without the RPMs even changing. All you hear is a little more whistle from the turbo and you're up the hill. Would be awesome to see a small turbo 6 in the next gen (like the Ford 2.7/3.0) but don't see that happening.

 

Never had turbo lag with my GTi and the 2.0. On my Subi, yeah...

 

I had tons of it with my F pace and my old WRX

 

I’ve owned several Audis with very little lag. Zero in sport mode. The Wrangler has a turbo 4 available, don’t know how it does off road, though. A turbo 4 can have gobs of torque with a flat curve.

 

If the turbo is small compared to engine displacement, it should be fine I would guess. Audi, has lots of experience with Turbos. Everything they do is turbo, pretty much. I drove the jeep wrangler turbo 4 and it felt laggy to me. It's pretty easy to tell if you have a boost gauge. All turbo cars have lag, that's expected. If a turbo starts boosting in the low 2k rpm range, that's good. If it starts boosting in the high 2k rpm range thats not good unless you are using a huge turbo for racing reasons. Like a supra.

 

Things are really different than even 10 years ago with turbo engines - there's definitely not 2 or 3 seconds of lag and then whoooOOSH like you get with an old 300ZX twin-turbo.

Most of the new mass-market turbo 4-cylinders in the 2-liter range have really strong low-end torque but don't really rev out (perfect in a truck, and great for how most people drive cars). The Wrangler 2.0T is a little torque monster, very relaxed and just wafts along on a big wave of torque, shifting at 5000 RPM, even lower than the Toyota 2.7. They almost have a turbodiesel-like powerband, totally fine with an 8-speed transmission.

Personally I really like a smooth, revvy engine like a Honda K20 in a car, but I think many people agree that the Toyota 3.5 isn't the greatest choice for the Tacoma. Some of the more performance oriented engines like BMWs and Honda's 2.0T will willingly rev out to 6800-7000.

 

Correct me if I'm wrong, but the Ranger is not available with a manual transmission; some of us never learned how to drive cars with automatics.

 

Apparently you've never driven a VW GTI, Audi A3, or anything else with one of VW's EA888 engine.

 

Turbos don't make boost based on rpm. It's based on engine load.

 

I can imagine that higher RPM not equal to higher turbo boost because in the case of engine braking, the RPM can be quite high, but the throttle body is closed and no fuel is sprayed and no combustion to produce exhaust gas, thus no boost.

Other than that, shouldn't higher RPM produce more exhaust gas and thus more boost? Or I'm missing something here?

 

That's very strange for a truck. It used to be that manual = cheaper (that's why we got a manual when we bought our `97 Civic brand new) but now it looks like to get manual on a Taco you have to get one of the TRD versions. SR5 and SR don't look like they come with the manual.

Also, kudos for proper use of the rarely seen semicolon.

 

No, I have not. I have driven lots of turbos.

It's more than just engine load. Take a 2 liter engine and stick a garret gt42 on it and tell me you can start making boost at 2200 rpm. All the load in the world will not make that rurbo spool at lower rpm. So it's not just load. It's a combination of where you want your power range to be and how much you are willing to sacrifice. Ever seen the power curve on a 1600hp supra? Show me the boost at 2200 rpm, lmao

no you are not missing anything and this is correct
