Whats the difference? I know that one has more HP but why what makes the extra HP?

 

from the more than you probably want to know about the CL thread.



HIGH PERFORMANCE POWERTRAIN

Driving the all-new CL are two variations of Acura’s 3.2-liter
24-valve VTEC V-6 engine. The 3.2CL’s powerplant creates 225
hp, a 12.5-percent increase from the previous generation 3.0CL
coupe (200 hp). The high performance 3.2CL Type S produces
30-percent more horsepower than the previous 3.0CL with a class
leading 260 hp. This is achieved through an all-new, dual-stage air induction system as well as numerous other performance
enhancements, resulting in increased power and torque without
increased engine displacement.

 

Ok its says "This is achieved through an all-new, dual-stage air induction system as well as numerous other performance
enhancements." What are the OTHER performance enhancements? Also whats the all-new, dual stage air induction system?

 

it's basically in the heads. Look for heads to bolt up.

 

check the thread for more details, you might be able to find your answer somewhere in there.

 

The Type S has a freer flowing exhaust as well.

 

i believe the cl-s has freer flowing exhaust, dual air induced intake or something, and two level vtec, higher compression, head is diff, and the tranny is diff, and it has a higher redline. but i'm not sure about the two level vtec, i could be wrong.

 

no two stage/level VTEC... but the VTEC on the Type-S kicks in lower (4800 RPM).

Also, tranny is the same....

Other then that, everything else looks right

 

true, but the headers are the same

 

the j30 has a two stage vtec I believe

 

Really? Never felt any VTEC difference between the P and the S. Maybe I just didn't notice....

 

no it's only in the J30. The j30 has a vtec system that isn't used in anything else. I've been trying to find the post that explains it but I can't find it anywhere

 

Ahh, OK.. so only that engine. Makes sense then that it felt the same.. b/c there's no difference

 

it's about time someone asked that question.

i have been thinking about that question ever since year 2000

 

Only DOHC VTEC has two stage VTEC.

 

j30 use a VTEC-E

dual stage induction? can someone please explain that?

 

This system uses a large, two-chamber intake plenum separated by a butterfly valve, which is opened by an electric servomotor above 3800 rpm.

HUH?

 

Roddy, below 3800rpm only one valve is open which supposedly increases torque at low revs. After 3800 the second valve opens to allow more air into the engine, because at higher revs the engine needs MORE air to produce more torque (if I understand it correctly)

F23A4, DOHC is not really dual stage VTEC .. there is only one stage of VTEC but the separate intake AND exhaust cams use VTEC, instead of just varying the intake side of the cams like on our CLS motors. Thats why our intakes sound sick in VTEC but our exhaust note doesnt change much, but on my buddies H22 DOHC VTEC prelude, the whole car (intake and exhaust) just sounds like its been posessed in VTEC. There are other kinds of vtec that ARE two stage though .. can't remember which ones but some of the other kinds of vtec are VTEC-E, iVTEC, and 3stage VTEC.

 

Yeah the VTEC-E is teh suck. I swapped out my cams for Type S cams. Once I tune it, I'll yield more power. Without tuning, VTEC hits harder but torque is at a loss.

I know the cams are different, the heads are different, pistons(higher compression on S), intake manifold dual stage, free flowing exhaust b-pipe and mufflers, higher redline, lower vtec engagment. Stiffer springs and shocks, bigger wheels, preforated and sportier seats, bowling ball and silver trim, and maybe a few other things, but thats all i can remember.

 

Could TL-P have VTEC-e cams also? I guess they got the 15 extra hp from the .2 liters and maybe TB or head?

 

So what all has to change in the 1st gen 3.0 to get it pushing out the power of the 3.2 without using bolt-ons.

 

unless u supercharge, u wont be close without bolt ons. With all the bolt ons, u may come close to a tl or cl-p and maybe exceed it, but to get to the type s level, u will need all the bolt ons plus supercharger.

 

I'm sayin what all in the engine has to be changed, like boring out 3.0 to a 3.2, head work ect...

 

not sure about that, there is a fellow 3.0 owner who is dynoing over 200 to the wheels w/ bolt ons and type S cams. That's on about avg w/ type S stock cars.

 

heads, intake manifold, boring out the block, ecu

 

Yeah we got a couple 195+ NA guys with j30a1's. It's pretty much intake/header/exhaust/UR pullies/plugs/VAFC tuned and maybe a helix tower.

 

the clp wont kill the cls if we were talking turbos. Due to lower compresion ratio, so if you are really serious and dont mind spending the money i'd suggest doing it.

Personally i own a cl-p, the only thing i like better are the seats, bought it used so no choice really

 

maybe this is a dumb question but whats a helix tower

 

I wish that could be tested but the tranny will blow before you find out.

Helix power tower is a throttle body spacer. Good for like 1-2 hp and ft-lbs.

 

i know of a couple of guys using cams and getting decent power, but #1 cams arent exactly bolt on, and #2 in order to take full advantage of the cams u would need a vafc and dyno tune it.

If i had a 3.0 i would do cams then get a vafc and a type s intake manifold with throttle body. I would have the manifold put on and dyno tune everything. You can have the IMRC hooked to an rpm switch that will open up the second stage intake in the new manifold. I bet a 2.0 will see some good gains from that. I myself am doing the cam swap, and intake manifold this summer.

 

Let us know how the manifold swap goes over at www.v6p.net. We got a guy who did it but couldn't get the intake manifold to work. His name is SoCalV6. Maybe you can bounce some ideas off him, he's pretty tech savvy.

 

if you do get the manifold swaped i would like to know, i have seriously considered what it would take to gain the power lossed to the the part differences, then i just decided to get headers and intake. I guess i'm gonna try and get the cls exhausts.

 

So whats different about the exhausts and where can you get the cams and manifold with throttle body
