Are they gonna call it the TSX 335i?

 

I just want turbo boost in the next TSX and call it a day.

 

If they put out a Type S option, I would pay for it, depending on the gains. I hate the Type S TL, just cause I dont care fo TLs, but if they get 250-300HP range, I wouldnt have an issue with an increase in cost of $4-8K. 33K would be great, but I think thats too low to expect. After all, its not going to be for everyone, just ones that want to pay for more power.

 

toss it and get the new one.

 

 

LOL, if you want to stick to a piston speed of about 4500 ft/min, then you NEED to destroke it to 86mm. At 99mm, 7000rpm, the piston speed is 4547 ft/min. When destroked to 86mm, 8000rpm, the piston speed is 4514 ft/min. Fine, you can have 87mm, which gives 4567 ft/min. But that's about it for a mass-produced engine. If you want to go any higher, you'll looking at FRM/Nikasil liners, not cheap on a mass-produced engine. 90mm stroke @ 8000rpm, isn't going to happen on a mass-produced engine. You'll need lightweight and coated parts for that which means the cost will go up. Since you guys don't want to pay 10k more over the current price of the TSX, I don't think Acura will go this route of a new block or use reinforced internals.

 

in any case, a vehicle that drops in mid-to-late 2008 would be considered a 2009 model

 

Acura Dealers are saying 09, so was the press release that can be found on MSN auto from the detroit auto show

 

I haven't been here in a while.. Still enjoyin my TL-S.. but my next car will be the Turbo TSX coupe.. and here it is with it's Honda concept name.. the " Sports 4 *concept* "..

Whoa tiger... Why are you fixated on an 8000 RPM redline? And more importantly, why do you use that as a vehicle for rebuttal? I've never requested something so lofty. "LOL" is correct.

 

I think it's because I have a fetish for 8000rpm.

 

I-4's are inherently unbalanced. This can be addressed to some degree with balance shafts, but 2.5L is about the limit. A boxer 4 (horizontally opposed banks of 2 pistons each) is inherently balanced without any additionaly balance shafts, but it requires 2 cylinder heads so they are comparatively rare.

The 1.8T was smooth mainly because it was small (and the dual mass flywheel also helped).

 

I think porsche did make a 3.0L I4... but they only got 200hp from it because it couldn't spin at high rpms while still being stable.

 

236 hp for the Porsche 968 -- http://www.968.net/images/images/968...al_data_01.jpg

 

Acura really should tier their products. They now have the TL & TSX as 2004-2008 & the RDX & MDX as 2007-2011. 1 per year would keep the public interested in their product line. Since TL sales are on the decline while TSX is still going up, I would change the TL 1st but if they go w/ the European Accord schedule, the TSX would be due next year {altho I have heard rumblings that the next TSX is not going to be the European Accord}.

The TL is due for some major improvements especially since even the Lexus ES350 has more HP. This gives the TSX @ least room for optional power like a turbo, hybrid, diesel or 6 cylinder. Hopefully this will silence all the complainers of Acura offering sub-entry level luxury cars.

 

Haha... Fair enough!

 

They did 236bhp out of the box. The factory redline was 6800 RPM I think. A friend of mine at the Audi/Porsche dealership had a 968 that he modified. The engine itself was stock but he replaced the PROM, exhaust, etc. The new rev limit was 7600 RPM and the engine seemed to like it--it produced volumes of power up there and sounded awesome to boot.

Piston speeds aren't as much of a limiting factor like they are in a Honda-centric world because the Porsche engine's displacement comes from a vastly oversquare design (104mm bore, 87mm stroke). The careful design of the pistons, cylinder head, and balance shafts all kept the ginormous 3.0 liter 4 cylinder very smooth at high RPM. It is probably still the best large displacement 4 cylinder engine ever made. You get what you pay for.

If the balance shaft belt jumps a cog... then it isn't so smooth anymore. Feeling a deliberately unbalanced 3.0 liter 4 cylinder is quite a experience.

 

Too bad the next TSX will still be built to a price... If they gave the "type R" treatment to the engine, it would be so much better.

I still prefer the E30 M3 EVO's engine though.... 238hp from a 2.5L inline4 with no lack of low end. That was a beauty.

 

oh you heard that too?

 

From an OZ article:
http://www.goauto.com.au/mellor/mell...2572A300813123

NOOOO! where is my 2.3T engine, aarrghhh!!!

at least they ain't putting a V6

 

booo.....definitely not the news I was hoping/waiting to hear.

 

More rumours of a 2.5L engine. I have no problems if thats a 'base' engine but they better be offering more than that IMO. Although a 2.5 with 225 HP would be great.

 

I think Acura should offer more engine choices and let the public decide on what they want. You don’t get any engine choices with none of the current brands except for the TL and the Type-S TL.

Hey Mr. Acura, gives at least 2, 3 or maybe 4 choices from the list below, with or without sh-awd:
- 2.2L-2.5L turbo diesel engine
- 2.4L I-4 High output (current engine)
- 2.4L + Hybrid
- 2.3L Turbo
- 3.0L V-6 High output
- 3.2L V-6 High output (upgrade all TLs engines to 3.5L and 3.7L for Type-S)

The TSX would have out sold the TL if it had a 3.0L V-6 option since 04.

 

for some reason, I believe the next innovation is going to be in transmissions. while horsepower may remain pretty close to the base models of other entry level sports sedans, I think Honda is going to introduce some interesting transmission technology, first with the incoming Accord and TL, and then the TSX. Of course, the differentiation with Acura and Honda will be SH-AWD.

Temple of Vtec had an interview on the new accord design with some head honcho, and one of the things he couldn't discuss was the transmission when asked specifically about it. Its a typical signal from honda that something is up.

 

Found this over at TOV

So the 08's will be in early to make room for an all new 09 TSX in the spring of 08

As far as an innovative transmission goes, I don't know. We haven't heard a peep about it. I imagine some from of DSG style transmission from Honda at some point but thats not really innovative. The beans were spilled on their new A-VTEC so you'd think we'd have heard something about an all new tranny by now as well. We'll see.

 

Interesting. Usually Honda is later than many makes to move to the next model year without a model change, but this may account for some of the current deals being offered on 07 models.

 

 

Ya, I should disclaim my own observation only as a hunch, and not true fact, so as not to mislead anyone. The fact that the person interviewed made it clear he didnt want to discuss something as established as transmission choices just made my spider-sense tingle. the fact that we haven't heard anything about it is just the way honda typically operates, and the A-VTEC revelation is more the excpetion than the norm....

But again, we can only speculate.

 

A turbo would be the kiss of death for the next generation TSX. Hopefully, Acura has learned from their mistakes like the RDX. The TSX really needs a small (2.5 - 3.0) liter V6.

 

Evidently, Honda already sells a DSG type transmission in Europe. The Honda I-Drive.

Also, it's evidently quite heavy.

The mistake was putting a small-block, high boost turbo motor in a 4000 lb vehicle and charging $33000 for it, and getting predictably lousy fuel economy since the smallish engine has to run on boost all the time to power such a large vehicle.

Drop the compression ratio in the TSX to 9.5:1 or so, add a lower boost turbo (although I'd vote for supercharger actually -- much simpler mechanically and more emissions friendly), and weeeeeeeeeeeeee!!! The TSX motor is easily capable of 225 lb-ft of torque (or more, but watch torque steer) and 250+ hp with just mild boost.

 

700 lbs TF?

 

Audi, VW, Volvo, Saab and Subaru do just fine using Turbo's in their mid size sedans.

 

like you said, i hardly see acura offering 2 engine configs (unless they did a type s) on the tsx w/ the way their model structure goes.

 

pretty sure thats 700 pounds as in the currency, not weight.

 

I would trade my tsx in for a new 1 if they would come out with a V6 TSX

 

Oops.

Mea culpa-- you're almost certainly correct. A traditional automatic is somewhat heavier (100ish lbs), so I should have realized this wasn't right.

 

That is not a DSG-type. That one is a single computer controlled clutch, ala SMG. DSG has 2 clutches with gears 1-3-5 and 2-4-6 on 2 separate shafts.

 

I am an Acura dealer and have had confirmation from our rep that the TSX re-design will be for the 2009 model year. AWD is definite and so is the turbo (not sure if that will only be on Type S or not). RSX will come back same time as TSX Coupe. I have also been told this release will happen earlier than Fall 08, and more along the lines of the original TSX release (Spring 08)

This will also coincide with the TL re-design (Fall 08) for 09 model year with AWD as definite and 3.5L and a mid-model re-design on the RL.

 

EDIT: AWD definite, no confirmation on Turbo yet........
