    Just in case, the thread title and pics on the website have been changes to a single twin scroll turbo. Depending on the design, they can spool early and quickly.

    The turbo setup could be great for sure, but that’s not going to change the main issue you’re having which is your gear ratio. And I’d be willing to bet gears are going to be quite a bit cheaper than a turbo kit.

    But you do you :thumbsup:

    Yeah, I understand the twin scroll set up. BMW's N55 used this which is the motor that came after the N54 in my 1M. The N54 uses two and it's regarded as a better platform that the N55. Not that that is necessarily the reason for that, but two is always better than one, right? ;)

    I doubt it will be cheaper, but I'm not ready to put more money into this right now either way so there will be options when/if I decide to do anything.

    It always depends. :D

    We've only had single turbos. A couple took some light massaging to get good, early spool. This last one spools like a freaking diesel.

    Twin are better, esp if one is a bit bigger.

    Yeah Im with ya, what number are you?? I imagine this leaderboard is going to see some big changes soon (hoping) as there seem to be a lot out at powdercoat. I am #198 and went to powdercoat on Feb 14th.

    That turbocharger is not going to build boost where you want it. You'll be exacerbating the situation. The airflow for that turbo is high up, 3-4k is where it builds boost. Even if you modulate the exhaust pulses, scavenge air to the turbo and keep it a true twin scroll you won't be able to spool up fast enough to achieve what you are talking about. It would be way more effective to use a centrifugal supercharger like magnuson. A centrifugal will make the 3.5L wake up real fast and where you want it; often times it results in better fuel economy because it can keep top gear uphills, etc. A much better use of your money would be going that route.

    Your issue is more the 3.5L to begin with. The Atkinson cycle should have never been used for that truck, the torque request under higher dynamic loads just isn't able to be achieved with that engine due to the torque curve, so it compensates by downshifting to get to the torque. Atkinson cycle uses the power stroke to build piston speed faster, which means that engine was basically built to rev out, not make power down low. Gears would definitely help especially with that much added weight/drag/rolling resistance, but a magnuson will do much better.

    As a note that I would guess that you know, the Atkinson cycle on this motor is simulated by the VVT. Even better, OVT dropped tunes for the MTs that deletes it for the most part. I am finishing up my first full tank on that tune and do like the much improved low end grunt. It is looking like MPGs are holding to pre-tune levels.

    Wasn't aware that they adjusted the cam timing to delete the Atkinson variation. I'd expect less MPG on a flat road with normal loads, but same or more MPG with load if you can actually keep 6th gear going into wind or up a small grade. Either way looking at their dyno graphs the improvement is about 12% down low, but max torque is still far out of reach; gears with a tune will probably get most of normal driveability back. I just highly doubt that that turbo kit will be able to spool below 3k which means you'll be downshifting on the highway to get to the boost. With a 6 speed you will really notice those changes, it'll feel like a roller coaster lol.

    It was a recent, special request that got spammed out as an option for the MT tunes. The MT folks also got the 7k rev limit kicked off. That's just a hoot, where I can finally feel the power dropping off.

    A well designed turbo kit could spool earlier. Our saab had a decent sized turbo for the motor (almost no taper near the rev limit). I could get nice spool below 2k and solid boost right around there. It just depends.

    Right. Not saying a better matched turbo wouldn't produce tq down low, but that specific borg warner they are advertising to be using is just not going to cut it for torque down low. The reason the smaller ecoboost engines get good economy is cause they have 2 separate tiny turbos that make up for the displacement loss. More air down low is what you want especially with this engine. I'd caution a bit to downshifts especially with a manual, super easy to over-rev and float a valve. Either way I expect Toyota to replace this V6 with a inline 4 turbo in the next few years.

    Nice catch!

    That is the great thing about a twin setup and the other possible ways to plumb them.

    A turbo 4 would be a great option. Although, it might not be a good idea to replace the V6. It will be interesting to see how it all develops.

    :cheers:

    See the issue is CAFE and EPA. They are in the business to make money and the way the regulations are set you can go two paths. Path 1: Keep current vehicle wheelbase and size and downsize the engine to get economy up; Path 2: Keep economy the same and increase the wheelbase and overall size. You can't have it both ways and either option costs more money which is why everything costs so much now since the green agenda is being burdened onto the consumer. I think with Ford and GM going with those options now and the future Toyota will have to innovate fast enough and still meet emissions and CAFE targets, but that means 4 cylinder will be an option or replacement. Just depends where you want to make money. Fiat just sells a bunch of muscle cars with poor economy and pays Tesla for ZEV credits and the gvmt for CAFE violations, but they make enough money that way it's feasible. Pick your poison...

    It is difficult, but we are still living in a golden age of power. I remember my parents thinking that V8 were dead 30yrs ago. They're still alive and doing well by playing the rules. The next decade or so is going to be pretty wild for many aspects.

    Interesting. I know that's why BMW had to phase out the N55 in the M2; it just didn't meet the emissions requirements. So they shoved the 'real' M motor from the M3 into it, the S55 and now call it the 'M2 Competition'. Poor owners of the original M2 are going to see their depreciation go through the roof...something we Tacoma owners never see!

    I agree, although I think we are at the end of an era for ICE sports cars with manual transmissions on offer that you can actually drive yourself without interference from all of the mandated safety systems. Grab them while you can.

    That is very true. With that, I lost any enjoyment for the exotics.

    I did my part with the nice basic Taco. Non-Tech / Non-Prem MT pre-TSS-P.

    On the sporty side, I got my bike. That will alway be my speed and cornering fix.

    I should be part of the next 10 frames back from PC.
    Email Feb 1st. - frame welded, panels formed and out to Powder Coat.
    Memory serves correctly someone 10 or more pages back showed that PC was a 4-5 week process (minus setbacks) b4 going to "in assembly" if that sounds right? 4th week was last Fri.:goingcrazy::frusty:
