I know my car would be in H3. But would any of the mods on my car bump me up to H2? The details on my car are in this thread: https://honda-tech.com/zerothread?id=90458

Make sure you read my reply about the changes I have made to the car so far.

Thanks!

 

Hard to say. I am not going to go back and review the entire thread but if I remember correctly there were things that made the car illegal for the challenge. I think the answer is in that thread. Shoot an email with ALL your specs to Shultz.

 

The rules can be found at honda-challenge.com

 

I reviewed the thread and saw this:

"My other concern is that this car isn't ECHC legal because it is HART-built and because of the hottie JDM cams/pistons"

Just because it is HART balanced and blueprinted?

The Rule book says teh following:

3.1 Engine / Drivetrain
- Engine construction and engine management
- Engines may be balanced and/or blueprinted. Overboring of engines is
disallowed beyond the factory authorized specification for an engine rebuild.
- Head intake and exhaust ports may be matched but cannot be machined beyond
1 inch into the head. Valves and valve seats may be machined (this does not
allow valves made of alternate material as OEM).
- Any OEM Honda ECU may be used, and may be relocated ONLY to facilitate
cage installation.
- Polyurethane or hard rubber motor mounts and/or inserts may be used

The engine is not overbored. It just higher compression JDM pistons and JDM cams. That is ALL that was upgraded in the engine.

 

I say read the rule book, then address any questions directly to the rules-makers. The rules really are pretty straightforward. I guess the issue now is what will be changed between now and next year.

BTW, the link to the Ebay auction doesn't work anymore anyway.

 

the ebay link will not be up, the car was sold last year. there are some details in the thread.

 

JDM goodies in the motor bump up to H1, where that stuff is legal... Its really not hard to put USDM pistons in and USDM cams... Then you will be h3 legal

 

That sucks. So even if there were aftermarket (ie. crower) pistons/rods, would it be bumped up to H1? There is no way this car will be competitive in H2 (let alone H1).

I dont believe it would be allowed at all then

*here is the engine rule for H1 Hybrids, which may apply to your car if you run it in H1*
"The engine, from the top of the engine block “down” to the ground, MUST be
constructed entirely of Honda parts. No aftermarket parts are permitted in this, the
“bottom end,” of a hybrid engine. Engine overboring is subject to the restrictions
listed in section 3.1 of this Rulebook"

No, it would be illegal.

 

Please carefully read the rules. Please.

Those pistons/rods aren't even legal for H1.

It's right there in the rules. Trust me.

 

Happens all the time. People perpetually buy and/or build cars, and read the rulebook after the fact. Quite often the result is an illegal car.

No. It would be illegal. *Please* read section 3.8 thoroughly. From 3.8.3 (page 11):

"The engine, from the top of the engine block “down” to the ground, MUST be
constructed entirely of Honda parts. No aftermarket parts are permitted in this, the
“bottom end,” of a hybrid engine."

 

So I could put aftermarket pistons in my car, right?

Thats what I don't get. It IS contrusctructed out of honda parts. Just not all USDM.

 

that was in response to you asking if you could use Crower parts. if you used the OEM honda parts, that would land you in H1 (ie, the jap spec pistons),as best as i understand the rules. best thing to do though is IM Karl as he knows best, since he made the rules. and also, read the dang rulebook

Brian

 

So that means, as the car is right now, with Honda Accord JDM pistons in it, that its Legal for H1..

If he would change to aftermarket parts, then yes, it would be illegal because its not a honda part

 

I did read the book. I was confused as to which class my car would be in.

 

Best advice is to make the motor legal for H3 and run it there.
This car *could* be competitive in H3 as it will have decent HP and a nice torque advantage on the rest of the class.

No way this car can be competitive in H1. Keep in mind that cars that are several hundred pounds lighter with much shorter wheelbases can legally run this same powerplant in H1. Youd get killed (not taking driver skill into account... strictly a car vs. car analogy).

I'm thinking that it would make a decently competitive H3 car though. You do need to undo some things to get it legal.

 

Yea, H3 would be my best bet. Even the H2 cars are much faster than mine.

Thanks.

 

well, now you know, and knowing is half the battle! GI Joe!

I don't, maybe H4, but not H3.. I have driven morgan's accord more than once around the racetrack, its basically a prelude with NO power...

It has 50less whp stock then a prelude, weighs the same, and is bumped down only one class.. I know the rules are molded after IT rules, but is there anyway the accord can be bumped down? JMO, and no Scott, im not complaining, just stating what I believe

 

All this discussion has centered around the engine. What is the cage like? Is it up to current specs? Is it 6pt or more? Does it pass thru the firewall? Is the brake hardware stock, USDM?

If the cage is current and the brake stuff is stock, then swap the pistons and cams for stock and run H3.

 

Also - since this was a former touring car does it have a seam-welded chassis? What kind of shocks are running on it? Is the interior structure cut out at all?

 

My accord generates maybe 80-90% the power of a prelude. so it is not that far off.

 

The cage is a 6 point. It HAD nascar style bars on the driver door but i modifyed it to match the passenger side so i can put a normal door (with a window) that is not gutted. it does not pass through the firewall. and the brakes are completely stock.

I may upgrade the calipers to Accord v6/wagon calipers.
