Requirements for Honda VX in ITA ?

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.

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

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
 
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
 
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.
 
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.
 
If you prepped the car to run H1, then consider SCCA ITE or STU classes. Less money and hassle if I understand your situation correctly.
 
I would run in F Production, ITE or STU, but the thing is that the only categories that are being run are ITA and I thinkg GT1 and GT2. From what I have seen ITA has around 10 cars and the others 5 or less.

Sincerely it sucks here, but I have to deal with what is available.

I am actually from Aguadilla.
I am still debating if I should remove the K-swap, fab a trans bracket that I can bolt to the chassis and weld the shifter plate for the shifter linkage in order to be able to put the d series in.
If you are around long enough there will be an event January 24th in Salinas.
 
Can someone confirm if a Y8 engine and tranny can be used? The z6 and y8 yield almost the same hp and have the same tranny ratios if not mistaken.
Thanks
 
No, must be Z6 stuff. If you put a Y8 in there, you're mixing different generation drivetrains with chassis it never came in from the factory. And they're not exact enough to eachother for it not to matter.
 
Y8 2nd gear is different when compared to the z6...

Also, the y8 has different intake runners and slighty different head... so it can not be legal for IT (edit: added text) in your EG.

There are plenty of z6 blocks/heads and trannies stateside that you will find on ebay or www.d-series.org. If your region allows it, you can look into a JDM D16A which is the exactly the same as a z6. Plenty of JDM importers will have a low milage one for under $1K.
