ITR Cars

Here is the list of ITR cars at the moment that are in the ITR proposal. Bear in mind the formatting might be a little off, and, some of the years are wrong (we know which ones) but the final draft/edit has not been done. Personally, I think there are a lot of cars to choose from and don't see any that stand out as perfect class winners, but I do know a few I'd be interested in building!

Acura Integra Type R (98-01) DOHC I4
Acura Legend (91-95) SOHC V6
Acura RXS-S (02-04) DOHC I4
Acura TSX (04-06) DOHC I4
BMW 325i/is (92-95) DOHC I6
BMW 328i/328is (96-99) DOHC I6
BMW 330i (00-04) DOHC I6
BMW 635 (83-84) DOHC I6
BMW M3 (88-91) DOHC I4
BMW Z3 (97-00) DOHC I6
Chevy/Pontiac Camaro/Firebird (97-99) OHV V6
Ford Contour SVT (98-00) DOHC V6
Ford Mustang (99-04) SOHC V6
Ford Taurus SHO (89-95) DOHC V6
Honda Prelude (93-96) DOHC I4
Honda Prelude (97-01) DOHC I4
Honda S2000 (00-03) DOHC I4
Lexus IS300 (01-05) DOHC I6
Lexus SC300 (92-00) DOHCI6
Mazda 6 (02-04) DOHC V6
Mercedes SLK (00-03) SOHC V6
Mitsubishi 3000GT (non-turbo FWD) (91-93) DOHC V6
Nissan 300ZX (89-96) DOHC V6
Nissan Maxima (00-01) DOHC V6
Porsche 911SC (78-83) SOHC F6
Porsche 944S2 (89-91) DOHC I4
Porsche 968 (93-97) DOHC I4
Porsche Boxer (97-99) DOHC F6
Toyota Celica GTS (00-02) DOHC I4
Toyota Supra (87.5-92) DOHC I6
Toyota Supra (93-97) DOHC I6

I also think there will be room for a few other cars (notably the 94-95 Mustang GT, others too) in here but we wanted to be conservative on the first round through.

Best,
Ron
 
Note that you'll see some years here that cheat on the "5 year rule" for eligibility. It is NOT the intention to change that rule for ITR. Those years are included only for planning purposes, where the make/model is known to not change across them.

In a T2 configuration a Boxter turned a 1:12.9 @ Nelson Ledges, that's a 2mile track w/ 13 turns. FYI I see cars with really big brakes.
 
Wow I see some cars that in IT trim will be seriously fast!! 968 911 Boxter Supra S2K...nice!!!!!

My '06 GCR says that a T2 Boxster is a Boxster S. That's not what's being considered for ITR.

Woops I forgot the S. From the car list I see, the should be as fast as National AS times, maybe faster, if were allowed 17 x 8.5" Wheels.
 
Of course different cars will do different lap times on different courses, but, we think that the top cars will be in the EP range.

The 911 is my sentimental fave, although it's a pricey choice, and the process doesn't account for the air cooled cars properly. Sad....

Another fave, the RX8 didn't make the cut, for fear of huge rotary gains, but I think the engine is much further along in the development curve, and electronics have vastly improved, which helps eliminate compromises, so we won't see the gains we have in the past. But, as of now, it's not an R car, as we chose the cars to be clear "fits" without setting off alarms.

I envision certain cars left of the list being 2nd round shoe ins, and others getting solid discussion.

But for now, it's a great list with lots of great choices!

I don't doubt that - we've got top drawer (Chet Whittel and others) S cars surpassing some AS times here and there. I'm sure R will beat that.

Considering S cars go around there in the 14's and A cars in the 15's...should be in line [/b]

Check again, AS cars run 1:13- 14 @ Ledges (1:13.1 track record) and 1:38's Mid O.

Isn't that okay? New cars have much bigger brakes than cars of old. Yep, and the S was in there but had to be removed due to power and weight concerns. It couldn't wear enough weight and it was far higher than the class hp ceiling.

E46 BMW 328, the first year or two before the 330ci and 330i... I don't know exactly which years but I want to say 99-00

You are correct with the years. I have a 2000 328i for a road car.
 
Jake,

I think you're going to see the top ITR cars 1-3 seconds faster than the top EP cars.

Maybe, but I doubt that it'll be faster than either B or D Production :D

I wrote my e-mail to the CRB :cavallo: Have you? :024:

The Mustangs and Camaro's listed in the proposal would have a hard time being competitive in ITA, much less ITR. There needs to be more thought given to domestic models. I hope there will be at a later date.

I agree to a point - you have not seen weights. I am an advocate for a couple of domestic V8 models that I think will indeed fit quite well in this bunch, but they were left out on the first round. See the ITR Mustang (SN95 model, Jeff made a mistake with Fox platform and the drum brake cars) thread here, but let's not turn this thread into "in or out" because this is definitely a second round process.

Regardless, there is a fine selection of cars on the list and I think the class will draw some folks interested in running there!

Nissan Maxima (00-01) DOHC V6

I'm curious... why only the 2000-2001 Maxima? The '89-'94, and '95-'99 versions out there are fairly potent as well...

the '89-'94 were a SOHC Cast Iron 3.0L V6, about 195hp stock... (might be better in ITS at the weight these things are...) I think the '95+ versions got a DOHC aluminum 3.0L V6 and had closer to 225hp or so...

I know the earlier cars are plentiful and donor cars are CHEAP (< $2500 in many cases...)

Just curious...
