Is there a Timing Belt on the 2.4

Recommended Posts

Hi all,

as newbie and in the process of shopping for a 07 or 08 Camry I have the question of does the 2.4 , 4 cylinder have a timing belt? I did a search and it appears that tere was on the 2.2 but saw no reference to the 2.4. I looked last night and my best guess is no on the 4 cylinder ans yes on the 6 cylinder.

If yes on either, are these interference engines where a broken belt typically means severe engine damage?

Model most interested in 08 SE with 2.4.

Thanks

I'm pretty sure it's a timing chain, not a belt. That 2.4 is a nice 4 cylinder...very powerful.

Leighcm,

you are correct the 2.4 has a chain.

Also for those shopping the new 3.5 Liter V6 also has a timing chain Vs the belt on the 3.3 Liter. This information is per the dealer I am negotiating with.

Every once in awhile I get to be right! (it's good to get confirmation! :P :lol::rolleyes: )

That 3.5 liter is another fabulous motor. I think it's pretty much the same thing I have in my GS350, just tweaked slightly for every model that it's in...IS350, GS350, ES350, Camry, etc.

It's the same engine (2GR-FE), but the one on GS350 (2GR-FSE) has twin injection system. Satndart multiport + direct injection. On low and medium load ECU uses both incections to make more precise A/F mixture. On high load it uses only the direct injection for maximum power.

Actually I heard rumors, that the new 2008 Supra (which should be released in October 2007) will use 2GR-FSE engine.

Nope...that's the Lexus LF-A, actually LF-1. Coming soon to a Lexus dealer near you in a year or two. Approximately $150-175k. V-10, concept car in Detroit 3 or 4 years ago, pre-production model just shown in Monterey at the Concours d'Elegance a month ago. I'd love to have one, but I think it's a tiny bit outside my budget.

Press release:

Lexus Unveils Two High-Performance Vehicles at the 2007 North American International Auto Show

01/08/2007 Detroit

View Webcast From Lexus Press Conference at NAIAS

January 8, 2007 - Detroit - Lexus unveiled the IS-F high-performance luxury sedan and the LF-A sports-car concept at a press conference today at the 2007 North American International Auto Show (NAIAS) in Detroit.

The all-new 2008 IS-F high-performance luxury sedan will deliver more than 400 horsepower from a 5.0-liter V8 engine when it goes into production. The LF-A supercar concept is equipped with a V10 engine that produces more than 500 horsepower. Together, the two exciting new cars make a dramatic statement of Lexus performance.

The IS-F and LF-A are very different vehicles, yet they share the same DNA, design philosophy, and heritage. Prominent in both vehicles, the "F" designation was first conceived nearly 20 years ago with a project internally coded "Circle-F," with the "F" standing for "flagship." This was the original code for what became the Lexus Division. The Circle-F designation further evolved into the code name Flagship One, or F1, and the first F1 concept developed into Lexus' first vehicle, the LS. Since then, the "F" code has come to signify a special vehicle program within Lexus that falls outside the normal engineering and development process.

"Lexus has long been perceived as the maker of mainstream luxury vehicles, but the unveiling of the IS-F and LF-A not only changes this perception, it also introduces a new Lexus marque," said Bob Carter, Lexus Division group vice president and general manager. "The 'F' shared by both vehicles is the signature for a new high-performance marque conceived by an engineering team that dared to turn their dream of 'a Lexus like no other' into a reality."

IS-F Performance Sedan

Much of the development of the new IS-F took place at Fuji Speedway and the Higashi-Fuji Technical Center in Japan. The IS-F is based on the proven rear-wheel-drive Lexus IS, which is equipped with a double-wishbone front and multi-link rear suspension. As well as the IS performs, Lexus engineers demanded much more of the all-new IS-F. The result is a performance tuned 5.0-liter V8 engine, topped with specially engineered heads fed by a two-stage intake system, that produces 400-plus horsepower and more than 350 ft.-lbs. of torque. The all-new IS-F is equipped with engine-oil and transmission-fluid coolers for high-speed performance and a cylinder head-scavenging oil pump for high g-force driving.

The IS-F engine is mated to the world's first eight-speed direct sport-shift transmission. A new torque-converter lock-up control was developed that allows for a direct, crisp gear change through the constant lock-up of the torque converter in second through eighth gears. In Drive mode, the IS-F transmission performs with great smoothness, and the torque converter allows for great launch ability for fast standing-start acceleration that will register a zero-to-60 time in less than 4.9 seconds.

This unique transmission also features an advanced Manual mode. A pair of paddles located within a fingertip's reach behind the steering wheel enables the driver to make ultra-fast up-shift gear changes within a tenth of a second. Downshifts are accompanied by automated and incredibly precise throttle blips to match engine RPM to vehicle speed.

The impressive acceleration achieved by the IS-F requires it be equipped with heavy-duty Brembo brakes designed to the specifications of the Lexus engineering team. Huge, 14.2-inch cross-drilled front discs are gripped by rigid, powerful six-piston aluminum calipers, while 13.6-inch rear cross-drilled discs feature two-piston calipers. High-friction brake pads are equipped on all four wheels. The brakes are finished with the Lexus name displayed on the calipers, a first for a Lexus production vehicle.

The IS-F features custom-designed 19-inch forged alloy wheels as standard. The wheels were built to Lexus specifications by BBS and are surrounded by high-performance sport tires.

The attention to performance also extends to a modified suspension that lowers the entire car by more than a half-inch when compared to the base IS, and one full inch when compared to IS models equipped with 18-inch wheels. This specially modified suspension allows for an exciting and energetic drive, whether on a race track or the streets.

The IS-F features an all-new three-mode version of Lexus' Vehicle Dynamics Integrated Management (VDIM) system. In addition to the Normal mode, the new VDIM features a Sport mode that allows the driver to push the car even further before its braking-, throttle- and steering-control systems kick in. The third VDIM system mode is Off, which allows the driver to push the IS-F to its ultimate level of handling performance.

The attention to performance is complemented by modified styling cues that differentiate the IS-F from the standard IS. Lexus engineers provided the IS-F with a dual-exhaust system and quad-tail pipes, wider front fenders, and a larger grille and rear spoiler. Both the hood and lower intake were enlarged to accommodate and cool the V8 engine.

Like the exterior, the interior of the IS-F receives unique styling with aluminized composite trim and special surface treatments. The instrument panel includes an oil-temperature gauge and shift indicator-lights, while the "F" logo is showcased on the steering wheel and rear-center console.

In addition to the usual Lexus standards of comfort and convenience, the interior of the IS-F features specially shaped and trimmed seats, which hold the driver comfortably and securely in place. The special sport seats are available in black or a unique high-contrast white and black trim.

"The intent of creating the IS-F was not to be a competitor to other performance-sport sedans," said Carter. "Rather, the goal was to create a true performance sedan in a uniquely Lexus way-one that is totally authentic with a unique interpretation of raw driving thrill at all speeds and provides a whole new definition of 'usable power.'"

The IS-F will arrive at Lexus dealerships in early 2008.

LF-A Sports Car Concept

The LF-A sports-car concept was originally shown at the 2005 NAIAS to express a bold new direction in styling for the Lexus brand. The goals for the new LF-A are no different than they were with the original concept: To build a supercar with world-class performance that is uniquely Lexus.

As with all new Lexus vehicles, the styling of the LF-A is rooted in a design direction called L-finesse. The concept of L-finesse was used to shape and detail the original LF-A, and it was used to reshape, redetail and redefine this latest version. Lexus has further refined the styling of the new LF-A to enhance its exotic nature with a greater use of curved surfaces and interesting details.

The running gear of the LF-A is just as it was with the original, powered by a high-revving 500-plus horsepower V10 engine. Its front mid-engine placement, along with a rear-mounted transaxle and rear-mounted radiators, allows for excellent weight distribution. The horsepower, superior aerodynamics, and revised styling makes a top speed of 200 mph not only possible but probable.

An "F" logo, indicating the vehicle's status as a part of the new "F" marque, is located on each front fender.

"The first LF-A was a pure concept, but one that we went so far as to conduct engineering analysis on," said Carter. "This latest concept is much closer to a vehicle that we would bring to market, and one in which we will be gauging consumer interest."

Not even close. Different platform, different motor, different transmission. Same parent company, that's it. The Supra, the IS300, and the SC300 are very close, but the LF-A is VERY, VERY far away. Take it from a 3 time Supra & 1 time SC300 owner....

Do you want it to be the SAME car?! with SAME engine and SAME transimssion? You know.. They are advacing on that.. ;) Camry has GS350 engine.. so its not a Camry, right? Because it doesnt have an engine from 94 Camry :lol:

I like your way of thinking ;) :lol:

Yes, but saying it's the same car is like saying the Nissan 350Z convertible and the Mercedes SL65 are the same car...

The Camry is still the same basic platform as the 94 Camry, obviously with some major tweaks. Last time I checked, it was still front wheel drive too. The GS350 is closer to the IS.

Regardless of all that, yes I would like them to make another Supra. Here's some of what they need to do:

1.) Better fastening system for the targa roof...should be power or quick release.

2.) More structural integrity when the top is removed.

3.) Some of the little modern niceties would be pleasant: perhaps Nav, back-up camera, XM, CD changer, rain-sensing wipers, lighted vanity mirrors, heated memory seats, passenger power seat, Smartkey, VDIM (with an off switch), significantly better stereo, HIDs, cupholder.

4.) Minimum 100hp and lb/ft torque more (please retain the forced induction).

5.) Better storage space in the hatch.

6.) Better storage for the targa roof.

7.) Lower coefficient of drag.

7.) Price tag under $60k.

8.) All of this without a significant weight increase.

I'd like it in dark blue or dark charcoal with a black interior, please. Maybe black/tan.

Why da hell you you want more cargo space in a sports car? :lol:

Actually Toyota mentioned something about "filling the sports car's gap in its line-up". With some kind of hybrid crap. Now that's really NOT a Supra :lol:

I just want enough space to put a couple of CDs, maybe an MP3 player...I'm not asking for much. (Seriously, have you seen the cargo space in a 1993-1998 Supra?)

I'm conflicted on the hybrid bit. I like hybrids...they're fun to drive, torquey, smooth, quiet, and get decent mileage, but I really like some of the old school sports car characteristics: rumbling engine, obvious shift points if automatic, etc.!

Yeah, but unfortunately I only have a 2 car garage, so I need to make sure my car choices are a little versatile...right now, we're still unpacking the garage (having moved from a house with a basement into a house without a basement), so the three cars and two bikes we currently have leave no room for another car...
