2.0L Turbo I-4

so agree. I am ready to look at the new Z71 Chevy and would drop my 30k on that unless Toyota reveals the plan soon. and I mean before the Chevy comes out in <6months . (2015 Chevrolet Colorado, that is... )

 

You can't just "tune" an engine for power... Will def need some heavy upgrades to get 900 hp.

Not exactly. Lots of engines operate at a reduced power for better MPG's and to maintain emission standards. I think the older mustang 4.6 (300hp off the lot) got 30-60 hp with an "chip" as ppl call it.

The ford eco boost V6 is a great engine so yes, but it was specifically designed for low end power. The mentioned 2.0 is probably not designed for low end power...

Also for everyone's education, HP will almost always peak high. If you want to measure towing potential, stick with the torque curve.

 

You seriously just compared a 4.6 V8 to a 2.5L 4 banger? There is no way in hell the 4 banger gets an extra 60ft/lbs of torque from a chip, or reflash of the ecu. Let's compare apples to apples.

 

Turbo engine technology has come a LONG way guys...

BMW now has engines that provide full torque from 1500rpm all the way up to over 5000rpm as the rev to 7K+.

That said, I know this isn't a BMW, but it's very possible to optimize the setup on this 4-cylinder turbo such that it has superior power characteristics to even our 4 liter V6's in every way. Turbo engines generally have a very flat torque curve which is very desirable in a truck, typically.

However, the downside is that the throttle response won't be as nice, so it will not be as good for off-roading. A nice example of this is that Dodge doesn't offer the Cummins in the Power Wagon.

Even though I much prefer naturally aspirated engines (and we have 5 cars at home now and not a single one has a turbo), turbocharging is the way of the future. More power and better mpgs...

 

How about a 2.0L 4cyl that gains 58hp and 76lbft with just an off the shelf reflash? believe it http://www.goapr.com/products/ecu_upgrade_20tsi_trans.html

 

i had not seen the release info on this yet, it looks pretty promising. a turbo in a lexus, especially an IS would be sick! i had a sport cross IS (GITA) for a little while way back when. (ugly as sin but ran like batt outa hell, took only couple miles on interstate, SOLD!) i think back in 2003 or so, i forget. those little cars with awd ran awesome with no turbo! i have been into lexus for years, a super good thing is the warranty is AWESOME! to be honest toyota warranty sux! lol, i blew my first lexus motor running at 136mph when i dropped a gear while racing a camero and they picked it up, fixed it, no probs, lol!

here is the real point of the post i found this...

as kick a$$ as i think this is and cant wait for it, fact is there was/is already an IS200 ITS CALLED ALTEZZA by most peeps, and in fact the Altezza is the WHOLE reason people started wanting the chrome looking tail lights with the colored bulbs.

lol, google "tacoma altezza'


still cant wait to get hold of one though!


cheers,
disco



---- edit ----

for old time sake i started looking through old IS forum posts, ALOT of peep's state AWD was never in an IS200 or IS300 only IS250+ thats crap! sport cross AKA X-cross (euro/asian name GITA), did have AWD! i owned one!

 

No.

Not hard if it comes factory turbo'd

 

Hope this link works for you, Golf R stage 1. +57hp/58tq on 93 octane.

Depends on what you're doing with it too..

Heavy duty towing, maybe not the best. If you're like me and just daily driver with the occasional haul in the bed, that could be another story.

I have a 2.7 2 wheel drive and it does what I need it to do for now. If my needs change of course I'll have to get another truck.

 

Lots of out of date info on small displacement turbos in this thread. Small displacement turbos are the future of gasoline engines. Efficiency of a small displacement engine and power on tap when needed.

I have a 2012 Sonata 2.0t and it's simply amazing. Little turbo lag and pulls strong from the low RPMs through the the redline. 274 hp and 269 ft/lbs. Tq.

I average right at 30 MPG mixed. I've gotten as high as 36 MPG when trying really hard to get there. It might hit 40 MPG on a highway trip if you kept it at the speed limit.

Embrace the 2.0t. It's here and it's not going anywhere soon.

 

I meant "this 2.0T can be a great replacement for the current I-4". It also could be replaced the current V6 with different tuning.

Torque is between 1650 and 4000rpm.... max hp is between 4800 and 5600... Now, we need to see How much Torques at 1650 RPM. Lots of people who own trucks DON'T TOW (like myself) and this can be a great engine.

 

this is a most interesting discussion. Imagine if these HP and torque numbers are at the same RPM as the V6 is now. that would blow some minds. I would LOVE the same power and torque with 30mpg. I'd get an erection over that.

This is all cool and stuff as long as you can run 87 octane. And not so cool and stuff when the turbo breaks, and it will break...

 

True. Ecoboost is cool and everything, but there is a reason Ford has been at the very bottom of the consumer reports reliability rankings ever since they've been releasing more and more turbocharged vehicles.

 

Gotta run 93 octain with FI, but if its set up right u can run e85, which is like 105 octain, and usually runs $1.00 or more less than premium around here, but mileage will go down roughly 30%. So ur. 30 mpg would be more like 21 still, however price per mile would be about the same. $ 2.89 was e85 last i saw and 87 is 3.59 here today (gas just went up $.20 last week, e85 is prolly close to $3.00 now just havent noticed)

 

Since when do you have to run 91 octane with an off the lot FI engine? There are numerous vehicle out there running turbo's using 87.

 

I worked with a guy that had a newer gto (ls2 or whatever gm junk v8 6.0 they come with) his car went in limp mod when he accidently put 87 in it and it was n/a i assumed as proned to knock higher performance motors were all FI would require premium. Great news if not.

 

Never ran anything but 87 in the wife's 2012 Genesis coupe & it had a 2.0T. Wouldn't it depend on the compression ratio whether you actually need higher octane? Hell, I'd almost rather get a low mileage salvage V6 truck and put the motor & all the harnesses/ecu and stuff in my regular cab and just stay NA.

 

Yes, but compressors typically add compression and i didnt think about manufacturers lowering the compression enough to compensate from the factory, seems like that would hurt performance and be an extra step in making them that would be solved by higher octain

 

Many Turbos and SCs do not need premium fuel but they're leaving power on the table so to speak. Many times you can run either and get a bit more power w/ the premium. The ECM can adjust accordingly.

Turbos and SCs are far from unreliable. That's a common misconception that has carried over from the late 70s and early 80s. I'm surprised to hear it today. Most diesels run turbos w/o problems for 100s of thousands of miles on heavy duty 250/2500s, 350/3500s, 450s etc. and also on the Big Rigs. Auto trannys and clutches are the problem points with those super torquey motors. But most of that has been resolved. Issues come when you start modding these diesels for more power which is very easy to do.

Just because it's a small displacement motor does not mean it only gets torque and HP at higher RPMs. That's really based on the intake valve timing and duration. Also, you can account for high RPMs power/torque w/ gearing. Just gear it so the motor is in the higher RPMs w/ lower gears.

It's the future and it's not a bad thing. I think you'll be surprised when you get the chance to try out some of these smaller, turbo'd engines.

 

The 2.0 turbo would be pretty weak for towing stock, but check out this dyno of the Cadillac ats 2.0t, their factory numbers were pretty inflated, I'd guess the 2.0 in the new Lexus puts down similar numbers at the wheels. The gains are insane as you can see, that's with a ecu tune to run e85. The 2.0 in the frs has shown to not mind e85. With 250ftlbs at the wheels at 2700rpm you do some work
