tls260

The nsx and tls have the same engines, at least there the same size 3.2 liters, how does the nsx engine get 290 horsepower, i want my tls to have 290, whats the deal.

typeR

comptech headers

The NSX engine is also built with exotic materials like titanium connecting rods. I'm guessing it's much lighter than the TL engine in addition to other "magic" that's worked into it.

You might get close, but short of adding a supercharger/turbo or rebuilding the engine, I'm not sure you'll equal the NSX numbers.

what's really cool is when you stroke the 3.2 to 3.5 AND use headers, there's a stroked CL-S in SoFla with 315hp at the wheels!

I hope you know that the NSX is a 3.2L DOHC VTEC Motor. Ours is a SOHC and it isn't the same engine. Ours is a J block..the NSX is a C series.

Yes they are both 3.2 liters, but they are very different engines apart from V6. Second the NSX is DOHC and our engines are SOHC. The NSX revs up to 8k rpms. They might have the same block, which I'll be suprise if they do, but almost every other component is different.

Enjoy.

Sorry to correct you, but not at the wheels. 315hp at the flywheel.

Someone also have a TL-S with 335hp again at the flywheel. It was measured at the wheels and then by math came out with that number. I'm guessing 22-28 % lost.

or go here for plenty of information on Honda's exotic car. www.nsxprime.com keep in mind...I'm a NSX FREAK, I know as much as I can without even owning the car.

TL/CL - J32A1/Type S - J32A2

NSX - 91-96 - C30B/97-02 - C32B

Ray you're just a freak in general hahaa j/p mang

newbie question!!

as they have mentioned...it's different design and layout...

our 3.2 SOHC was carried over from the old TL...

the 3.2 DOHC is only available in NSX only....and it's a mid mounted engine...

they might have similar displacement and 30hp difference...but they are just like apple and orange...

vr-tls

My friend and I were just talking about this subject tonite. We were at his shop and he had a 94 NSX motor on the side and it wasn't pretty. Well it only needed some cleaning up. We were thinking bout a hybrid untill we match the blocks and they were a little bit different. Well i'm not sure who's quote the is but with money anythings possible.

More hp for the NSX with it's 3.2L DOHC V6 but if you notice the CL-S/TL-S 3.2L SOHC V6 had more torque...

RAdams

The NSX and TL/CL engines are quite different despite having the same displacement.

The NSX, at 3.66" and 3.07", has a larger bore and shorter stroke. Piston speeds generally dictate the extreme upper limit of an engine's RPM range, so the NSX uses a shorter stroke to keep the piston speeds in check. However, longer strokes generally provide more torque which is evident when comapring the TL and NSX engines as the TL has a longer stroke (3.39") but a smaller bore (3.50"). The NSX uses Titanium connecting rods to lighten the reciprocating assembly and allow for the engine to rev quicker (and ultimately, higher)

Another classic example of piston speeds dictating an engine's redline is the 3rd generation Integra. The GS-R/Type R and the RS/LS/GS/SE both had 1.8 liter motors, but that was due to rounding. The GS-R/Type R actually displaces 1797cc (or 1.797 liters) while the others displace 1834cc (1.834 liters) due to a difference in stroke. The GS-R's stroke, at 87.2mm, actually gave it the title of production car with the fastest average pistons speeds in the world. Since it revved to 8100rpm and had a relatively long stroke, Honda went to great lengths (which I will not discuss here as this post is already too damned long) to ensure it would survive at such speeds.

Bottom line: The displacement of the two motors is the same, but they are quite different in design, mission, and operation.

systek

great info guys, i definitley learned something new...

jbrown

Thanks for the correction, misinformation is the thing I hate most on these forums.

SpoiledMan

Just to add a little something. The last generation TL had the 3.2 from the defunct Legend and shares NOTHING other than similar displacement with the current 3.2 that is an evolution of the Accord 3.0.

ElegantTL-S

Yep Yep. And the Accord 3.0 V6 came from the first gen CL.

systek

thats what i was about to add...that 3.0 in the accord was in my 97 cl..which is the first time that 3.0 came out.

ElegantTL-S

beat you to the punch! :p :p haha..our engines originally came from a 97 CL...

systek

YEP, my cl was fun, but not nearly as fast as the tls

one quibble, the cl had a plastic dressing on the strut bar that covered all the wires, hoses and even the master cylinder w/plastic that really tidied up the engine bay when detailed. i really hate how they short changed us on this engine bay by taking that out.

now i know some ppl hate plastic in the engine bay, but if you've seen the 97-99 cl, you know what i mean.

ElegantTL-S

oh reallly?! can you post a pic? I never knew that. haha..can we yank it from the CL and put it in our TL-S? :p

systek

im not sure, but its worth trying... heres a pic of my old cl:






here is the url to the whole car: http://members.cardomain.com/systek

ElegantTL-S

I think it makes it look much cleaner. I think the people with the Accords can do it. hehe...oh yeah...man..the whole right side of the engine bay still resembles the 95-97 Accord V6's! haha. but then again..the whole car is a 5th Gen Accord.... :p

systek

yep, sure does...trickle down effect...first it was on the cls, now its on the accords

ElegantTL-S

hehe..yeah. trickle down effect! honda/acura has no creativity.. :p

Jaydef

and what makes the Type Ss different from the Ps. how do yall TlSs get that extra 35 HP??

systek

its definitely not that...think about the money they save and pocket doing this...add to this the premium $$$ they ask for their products

that is one thing that makes me :yack:

but at least it also means that i can service my own car cause the parts are all pretty much the same:
1. dropped my car myself
2. helped austin519 w/his ss brake lines
3. installed cai myself
4. on the cl, changed alt myself
5. on austin's tls, gave advice how to remove tls alternator
6. and the list goes on and on....

ElegantTL-S

Very true......I agree totally. Only us car nuts will actually realize these things. the other people who buys these cars...don't have a single clue! ah well...at least Honda is making money....sort of...haha. The lawsuit against them right now on the tranny issue..
