Overheated the Civic 2 years ago, and has been in storage ever since. Looking to rebuild motor and try to take some swings at the Mini's in HS SCCA Auto-x. Here's my checklist with some questions (go easy, I'm a Honda n00b)

- engine rebuild @ +0.020". Is there any other LEGAL changes allowed besides overbore?

- Koni Yellows. Does anyone make NEW factory springs? Old have 160K on them.

- Cat-back. What is a good lightweight cat-back for a stock z6?

- R compounds on ??? wheels? The wheels on the car are aftermarket cheapos, but 15" so I'll be changing them. What are some good, cheap, lightweight factory size wheels I can mount R compounds on?

What are some other suggestions for a 1994 Civic EX Coupe to run HS?

 

You can only go .010 over. That is the first factory overbore. Everything else on a z6 is either to be replaced or left alone if it isn't out of spec. You can't deck the head, so if you warped it when it overheated, you need to buy a new one. I like the Magnaflow cat-back as the rear section can easily be removed so you only have a 9lb exhaust that dumps in the tunnel.

I'm pretty sure HX wheels are legal, but you'll need a spacer to run them on the front of the car. 1/4" spacer is fine and should be legal as well. Double check the stock wheel width and offset though as I'm not positive about this.

225/50/14 fronts, 205/55/14 rears, hoosier or kumho. GSR/ITR front bar. You should be able to order new springs from Honda if you need them. If not, I think I have at least 1 set of stock springs that are still good that I wouldn't mind unloading for cheap.

I think this will depend on whether or not you have abs. I just put hx wheels on my car yesterday and didn't need spacers. My car is non-abs i.e. smaller brakes.

 

But the hubs are the same regardless of ABS, yes? If so, the only possible difference would be rotor hat thickness (with respect to wheel offset and spacers, that is).

Hubs are the same as far as I know. I'm not sure if ABS was an option or not on the EX so this may not even apply. My EG si does not have ABS so it has the smaller 9.4" (i think) brakes as opposed to the 10.2" (i think) brakes.

Rulebook says:

<TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote, originally posted by rulebook &raquo;</TD></TR><TR><TD CLASS="quote">13.4 WHEELS
Any type wheel may be used provided it complies with the following:
it is the same width and diameter as standard, and as installed
(including wheel spacers if applicable) it does not have an offset
more than +/- 0.25 inch from a standard wheel for the car. The
resultant change in track dimensions is allowed.
Wheel spacers are permitted, provided the resultant combination
complies with the offset requirements of this section. Wheel studs,
lug nuts, and/or bolt length may be changed.
Vehicles equipped with rims having metric specifications may use
alternate rims as determined by using the following procedure:
65
Diameter: converting the metric measurement to inches and using
the nearest smaller inch diameter rim.
Width: converting the metric measurement to inches and using
the nearest smaller 1/2-inch width rim. Offset and track must
still comply with the requirements of this section.</TD></TR></TABLE>

So my question is, what wheels were optional in '94? HX's are 5.5", did a 5.5" come out in 94?

 

redshiftmotorsports.com has a 'recipe' for success.

 

Redshift's "recipe" is STS specific though. This guy is driving in HS, totally different ruleset.

 

ah, ok. Sorry about that.

 

he is better goin into STS...more options for the car setup and can result in more fun! when it allows you some suspension mods and bolt ons its a much better experience

 

All depends on what you're looking for, and what compromises you're willing to make with the car. You say STS, someone else might say, "well ****, if you're going that far, why not AM?" I can verify that you can have just as much fun in GS as in STS or SM.

I'm not new to racing, and my main reasoning for staying STOCK class is because I think its going to be the most effective/easiest/cheapest way to turn a DD into a weekender to Auto-X. I pretty much plan on being able to get away with throwing some wheels/tires (maybe brake pads) on the car, adjusting the struts, and driving 5 miles to my local Auto-X on weekends. Other weekends will include 1200mi round trip road trips to places like New Orleans... where 3" deep potholes are considered "smooth pavement".

I definitely plan on eventually going STS, but If I want to go fast, I'd rather spend money on track days for my motorcycle.

 

No optional wheels for a 92-95 civic. The only factory available size was 14x5.5". I'm 99% certain the HX wheels are legal for a 92-95 HS Civic. I think I'm confusing them with the 88-91 HS Civics which have a 14x5" wheel? At any rate, just verify that the width and offset of the HX wheels are the same as the stock steelies. (I'd do it for you as I have both stock and HX wheels, but I won't be near them for 2 weeks to verify)

On the brakes, there are some oddball cars out there. For example, my 93 EX Coupe non-ABS has the 10" front brakes. 93 seems to be the only year that they did that though. All the rest are abs=10", non-abs = 9" rotors. HX wheels over the 9" brakes does not need any spacers.

Rotor hat thickness is not the issue, the larger brake caliper has a thicker bracket that intrudes on the wheel area. I know for a fact you can fit the HX wheels over the 10" rotors with a 1/4" spacer. I've done it first hand. No difference in hubs (well, there are two different bearings/knuckles, but the hub/rotor/wheel is the same on both).

Don't follow the redshift "recipe" if you're building an STS EG. I've built two of them and was successful in both, and his spring rates and bar suggestions just don't work on the EG chassis.

 

I know this might not help much but I'm also sure the HX wheels are 14x5.5" they are probably about 1-2lbs lighter than the steelies (from memory) since I haven't had HX wheels in a long time.

More then that. Mine are ~9lbs each. The steelies are closer to 18lbs each IIRC.

 

Check the specs on the 14" alloy CRX SI wheels. They may get you the size and offset you need withing the stock class rules.

I think the CRX wheels are 14x5". I know there was some reason that Chang never ran my HX wheels on his HS EF Si. He needed em too after he cracked two Kodiak's.
