Requirements for Honda VX in ITA ?

[Buitrex]

I have a civic Vx which I prepped to race with NASA H1, but I am not longer in the US and the only race class available near me is ITA class. This means that I need to convert my car to ITA specs.

I have read the rules, but still have a few questions that maybe experienced drivers related to this class and to honda may be able to answer.

-Can I use Coilovers? I am currently using PIC coilovers

- I have rear disc brake swap. Is this legal?

- Can I update my front brakes to Si ones 9in to 10 in or do they have to be the stock oem ones?

- Which are the weight limits? Are these with driver or without. Will the weight vary if I swap from the d15 to a d16 or d16 vtec? Can I swap the engine?

- What engine mods are legal besides I/H/E and the 1in porting to IM?

- Can I change the windows for lexan?

-Are fuel cells mandatory? From what I read they are not required.

-What tire sizes do people with hondas usually use? 13,14 or 15 and what width 205 or 225?

Any suggestions and other comments are welcome.

Thanks

If you read the GCR, you didn't read it very well. Almost al of this is spelled out pretty clearly.

I have a civic Vx which I prepped to race with NASA H1, but I am not longer in the US and the only race class available near me is ITA class. This means that I need to convert my car to ITA specs.

That is fine, but it means you will have to convert everything on your VX hatch to EXACTLY the specifications of a Si (only EG hatch classified in ITA). Everything, exactly Si. Luckily that's not too difficult. However, the biggest problem you're going to run into is your lack (I assume) of power steering. Racing in ITA as an Si will require it, so you'll need to install it.

-Can I use Coilovers? I am currently using PIC coilovers

Yes, that is legal.

- I have rear disc brake swap. Is this legal?

If the rear disc swap is from an Si (or an EX, which are the same), than that's actually something you'd need to do anyways. Should be a 201mm disc.

- Can I update my front brakes to Si ones 9in to 10 in or do they have to be the stock oem ones?

Like your rear brakes, you will need to have whatever an Si came with originally. Should be a 262mm disc.

- Which are the weight limits? Are these with driver or without. Will the weight vary if I swap from the d15 to a d16 or d16 vtec? Can I swap the engine?

Weight for an Si is 2330lbs, which is measured with the driver in the car. Again, everything must be Si spec, so a D16Z6 must be used.

- What engine mods are legal besides I/H/E and the 1in porting to IM?

I can't really go into all of that. Read the GCR. Quickly put, you can do up to .040" over and up to a 1/2 point increase in compression. Balance, but not lighten. All OEM parts.

- Can I change the windows for lexan?

No. OEM glass only.

-Are fuel cells mandatory? From what I read they are not required.

No, not required, but if you do have one, there are requirements to how it's installed. Read the GCR.

-What tire sizes do people with hondas usually use? 13,14 or 15 and what width 205 or 225?

In ITA, you can run a 14" or 15" wheel, that's no wider than 7". Plan to run a 225 tire.

Thanks for your post. That is all I needed to know.

Where are you located? You mentioned you weren't in the US? Wasn't aware that SCCA ran outside of The United States, Hawaii, Alaska and PR...LOL

[Buitrex]

It really isn't SCCA, but they go by their rules. It is in PR.

I read above regarding power steering. Is it mandatory that I add it? I don't see much difference in having it or not and I looked at the GCR and could not find anything specific to it.

Also, I read in the GCR about the heater core needing to be in the car, is this correct or I understood it in another way? My car does not have it and I don't see that it could make any difference in the car besides weight.

Thanks

[R2 Racing]

Yes, an ITA car isn't allowed to remove the heater core, and if your car (an Si in your case) came with power steering, than you must have it installed and operable. No, it doesn't say in the GCR "You must have your power steering installed and operable.", but it doesn't say you can remove it either. A classic case of "If it doesn't say you can, you can't." (commonly referred to as IIDSYCYC) way of thinking that will help keep you out of trouble with the stewards. If the GCR doesn't expressly say you can do it, than assume you can't.

[Buitrex]

If the power steering and heater core need to be in the car then I won't be able to change my car completely unless I buy all the parts and swap them in. I don't feel like spending the money and going throug the trouble of adding those parts in.

And Kevin's posty isn't just 'common wisdom'. It says it right in the ITCS. 'Only the following authorized mods are allowed'...

That means if it doesn't say you can, then you CAN'T.
