So,

This would seem to be a fair comparison... Certainly a cost effective car and quality vehicle...

Opinion: It could be a contender.

So, in the the comparison the CRX has a shorter wheel base, more Cubic inches, and less height and width...

What matters is how much better or worse the brakes are, how much more advanced or not the suspension is and whether the motor will respond the chiping and "normal" legal IT mods.. And of course whether or not they let it race at the same or similar weight.

In a direct comparison using Starbase Corp.'s VisDiff I see very minor differences, and if the brakes are as good or better and the weight can be kept low and the engine responds to tuning, then this is a potential CRX chaser.

But I need to know the braking "scores" and details of swept area and force applied etc. etc.

This sounds better than ITS for the EX... Maybe we'll build this and have a good time in ITA!

And just like "NoRaceCarYet" said... And of course whether or not they let it race at the same or similar weight.

I'm not sure I should let this out of the bag, but... Those 1.5L DX's were notoriously underrated from the factory. Most were much stronger in HP and Torque than the numbers suggest.

After reading this post I almost gave up the idea of prepping my EX for ITS and started searching the classifieds for DX cars. But then I remembered that EVERY single ITA race I've ever seen has had a bunch of M2M with cars banging into each other and everything else... I'll stick with ITS.

Yes, but the M2M I've seen happens back in the pack. Hopefully we won't need to worry about being back there http://Forums.ImprovedTouring.com/it/biggrin.gif

I'm wondering what it would take to convert an EX to a DX? I know that open a can of worms, but I've seen many IT cars "bump" up or down by simply changing engines. Then there is the whole VIN issue... Any thoughts?

Matt-

The VW guys have been running posts about this consistently... of course, theirs is a unique situation.

The Comp. Board will not allow you to "switch" a car's spec. The VIN number will usually tell you which model and trim level the car was from the factory, as well as some option codes.

VW GTI's seem to be a special case. In some cases there were no VIN codes to differentiate the GTI's from regular Golfs, or even 8v vs. 16v cars (ITB vs ITA, I think). In these cases it's not uncommon for people to "manufacture" a GTI racer from a Golf shell (See recent GrassRoots Motorsports for a perfect example).

I'm not implicitly familiar with the Honda codes, but I believe the EX and DX are not interchangeable.

Tom,

What about changing the VIN plates? How many plates do you need for IT?

If it takes purchasing a DX, then so be it. But if I can find a way to convert mine, "good for me"!

not a rant:::

The issue of manufacturing a car model is really only a concern if your competitors are a*s*o*e's I mean, who cares really...

I know a certain SSB Mazda protested a certain SSB Toyota a couple of years back for "manufacturing" the specific model after the car was totaled. This forced the second driver to rebuild his car again... but I can't imagine joe IT Driver would stoop to such a level - it's not legal per the letter of the law - but sheesh!

Sometimes a little comon sense would be nice..

I'm thinking DX Hatchback, painted just like Woo's! (my new hero)

;P

"NoRaceCarYet; I'm thinking DX Hatchback, painted just like Woo's! (my new hero)"

I like the idea, but, it's just yellow!

My question is that, are they (SCCA) going to class all Hatchback, Coupe and Sedan in ITA or just the Coupe?

Matt, it's pretty obvious what the rulemakers meant if you read ITCS p.6-7. I don't see any advantage to working around them. There are particular disadvantages.

You'll spend more money: sell your streetworthy car and buy a salvage or beat up model of the one you want. You can use the difference in price to buy more race parts. Okay, say money is no object to you...

The biggest disadvantage (IMHO) to "building" a different model then delivered from the factory is that if you're ever called on it, it's back to square one. The officials will put it in the car's logbook and then you're pretty much done with the car. You can take your race parts off and build another car but that's really not a lot of fun.

If you ever end up running at the front of the field you can bet your competitors will look long and hard at your car. Some people will call them a*s*o*e's but that doesn't help win the argument with the guys in the tech shed.

You have the maturity to sign your real name to your posts. I doubt you want it to be smeared with doubts as to whether or not you drive a legal car.

Cheers.

Thanks! I was just curious since I know the VW guys "create" cars and noone seems to care. I have an SSC EX and just wanted some member thoughts about a conversion. Picking up a DX should be no problem and the parts for them are EVERYWHERE! I'm going to start converting the EX to ITS and we'll see if any DX's fall in my lap.

For the record: My car is 99% legal. (I'm missing a few trim pieces that made it 1% illegal in SS.) It will be 100% legal next year for IT or LP Prod.

Thanks for the input!

94 Civic DX in ITA. That was my request for classifacation into IT. Competative? Not with my skills and budget http://Forums.ImprovedTouring.com/it/smile.gif I have a few things to do, like the window net and oil catch can then I'll get car tech'd. I'll enter SFR's drivers school in Feb.

This car is my only shot at racing. Long story, but here I am chasing a dream.

I've done the all of the IT legal suspension mods. It handles much better than stock. There is a large "import revoloution" world of suspension parts for this car. That's a great thing. But, there are't any chip mods that I can find for this car. I sent in the engine code and ECU numbers to many chip companies and they all said they have nothing for me.

As for HP and torque, the car kinda slugs and chugs uphill towards the corckscrew at Laguna. A new airbox/intake and some advice from a Speedvision driver made me and the car faster. Like I said, I have no talent. Maybe I'm staying in 3rd to long for no real gains. I am working on a program to data gather the usable RPM range.

My biggest problem is the gear ratios. I do most of Laguna in 3rd gear. When I start to shift the breaking markers appear. finding some light weight 13x7 wheels is tough. Panasport is all out until the next shipment from Japan. The car came with 13in wheels so I gotta stick to 13.

OK I gotta go now.

I sure hope they allow us to run the HB - I'm not a fan of the Sedan..

I have not personally used them for any work but they have a very good reputation among Honda Hybriders. In particular I have spoken or emailed with many 88-91 CRX owners who have Zdyne equipment in ther turbo, s/c, nos injected, LS/Vtec, B18, or B16 equiped cars and are very happy with the products.

With the Gold model I belive you have the ability to program your own setup for the ECU. There are even boards where users post their particular programs for certain setups and swap with other people.

Later,

Looking at www.kbb.com (http://www.kbb.com), it seems like the DX might have the advantage of being a cheaper donor car (for a 1990+ model) than the other ITA options. However, this pretty much spells the end of ANY hope that the EX could be classified in A.

I still think there is a performance gap between "real" S-cars and the 2-litre 16v cars. Maybe we should start a new class--IT2.016v! They can run in GT4 in Nationals and at the Run-offs! Yeah, that's the ticket...
