just curious Intake, header and exhaust will get me into Street Modified?

Would those really be enough modifications to get me that high?

After reading I would have though maybe Steet Prepared? see excerpt below....

"Street Prepared (SP)
Street Prepared cars are allowed significant modifications over stock, but many are still dual-purpose cars. Some of the permitted modifications are: any legal modification in stock; any springs that fit stock attachements; any sway bars; any wheels & DOT-approved tires; any induction for the engine (except that cars that were originally normally aspirated must remain normally aspirated); and any exhaust including headers. Compression ratio and camshafts in the engine must remain stock.
Cars prepared to Road Racing Improved Touring and American Sedan rules are permitted to run in Street Prepared, but as with Showroom Stock, rules "mixing" is strictly prohibited."

 

the clutch and flywheel throw you in SM i think. if you just had the intake header, exhaust your index would be in BSP

 

Lol well what they don't know won't hurt! j/k
Ugh that really sucks though, my oem was worn so I'm not going to replace it with another stock one, that just doesn't make sense! Who puts a stock disk back on after going through the trouble it takes to change our clutch???

 

Your mods put you into SM2. In order to move back down to BSP you would need to swap the AP1 tranny back into the car, or put a 2.2l motor in the car. 2 seaters can not run in SM.


The first thing you need to do is run the largest front bar possible with your stock suspension. I'd go with the Saner bar if I were you. You are clearly on the way to modifying the car further in the future so the Saner bar in combination with a nice aftermarket spring/shock setup will do you nicely.

 

I just happen to have a Saner bar for sale

Unless you would rather keep your Cusco bar for it's "JDMness"
I laugh at how ppl think anything JDM is good, but in reality, the "true" race parts aren't from Japan at all.

Anyway, just run SM2 for now, try it a couple times, see if you like it, THEN take the plunge with parts.

For your setup, the Cusco is not stiff enuf.

 

You would be in BSP. You're allowed to change the clutch and flywheel in Street Prepared. You are also allowed to update and backdate the engine separately from the transmission. AP1 engine, AP2 transmission, AP1 differential is allowed.

Everyone who said "SM" or "SM2", hit the books again!

 

Thanks guys.
I honestly am autocrossing for the love of racing.
I want to be competitive but I'm not de-modding my car to do that.
I'd rather be the slowest in the faster class and have fun than have to change my car.

Thanks again for everything. I'll look more into the saner bar. Would it benneficial to change the rear bar to the 06-07 bar since it's softer to maximize the effect of the front bar?

 

I feel a lot better today. I went up to the Coliseum where they were having an event today. I spoke to the only s2000 there a cr running a stock with the a gendron bar, evasive exhaust and hoosier a6 275's in the rear. He ran a 48 flat, quite impressive. I also spoke to a turbo scion tc who was running in sm class that was running 53's. The s2000 had the fastest time there. I feel quite good knowing that now since if i set my car up right it'll be equally if not faster than that cr, it'll just be down to the driver!! Good Challenge for me.

Thanks again everyone that gave me some advice

 

yeah because of the clutch i wouldn't de mod the car also. good luck

 

No you aren't.

Equipment and/or specifications may be exchanged between
different years and models of a vehicle if (a) the item is standard
on the year/model from which it was taken, and (b) the years/
models are listed on the same line of Appendix A (Street Prepared
Classes). The updated/backdated part or the part to which
it is to be attached may not be altered, modified, machined or
otherwise changed to facilitate the updating/backdating allowance.
Standard factory installation methods, locations, and configurations
are allowed. The updating and/or backdating of
engines, transmissions or transaxles must be done as a unit;
component parts of these units may not be interchanged.



If the AP2 and AP1 transmission were exactly the same (which they aren't) then you could do so.

If you could do the engine/tranny "piecewise" then you would see the ESP 4th Gen Camarobirds all running the LT1 '93 tranny that has a shorter second gear. But you don't because you can only use the LS1 T56 with the LS1 car. The LT1 T56 bolts right up, but the motor is obviously different so its not legal. All the fast LT1 motor'ed cars will run the '93 T56 though (well if they aren't they should be).
