I have the S2 transmission in mine
Love it! Actually have a usable 5th gear lol
Team - are you changing to the 5.12 diff as well? :suspect:

slvrstreak 10-21-2013 12:07 PM

also think about losing the bumper supports/crash bars as well
those things weigh a ton and it's not like youre going to need them for autoX

TeamRX8 10-21-2013 01:02 PM

In DSP we can only use the OE diff ratios. I plan to start off staying with the 4.44 ratio. May swap to the 4.77 ratio if I'm not hitting the 2nd gear rev limiter much. The S2 diff was available, but since I have the OS Giken lsd it seemed to make more sense for me to buy the R&P than a whole diff.

We can't even remove the plastic shroud on the crash bar, let alone the bar itself. It can't even be removed in SM, only in Prepared or Modified. It may seem odd ghat you can use a $4000 clutch/flywheel setup and nkt do that. The rules are the rules.

ah, didn't know that

The DSP build has begun! New aero from JoeFis Racing has been installed as well as a Sparco 383 wheel. The wheel is 330mm and feels amazing!

The install of the wing was a breeze and I can take the thing on and off in less than two minutes, with no tools at all. If you're interested in going the same route with Aero check out www.joefisracing.com!

The car was already paxing ahead of two time National Champ Jadrice Toussiant in his ESP Boss Mustang at last week's event, with just some 275 BFG's on and the steering wheel.

Looks great Mike, glad you joined me in getting the rear spoiler as well. :)

nuke0907 10-30-2013 10:58 PM

Man those are pretty light. I'm glad i snatched up my SSR GT2-H's 18x10.5 +43mm when i did. not quite that light but better than stock.

Wish I could find a set if 17x10.5 +45 SSR Type C or C-RS wheels @ 17.2# each. Supposedly they made at least one run production along the way, but I've yet to ever see a 2nd hand set up for sale ever ....


Zelse 10-31-2013 09:02 AM

BTW, now that you'll be in DSP...Does this mean I can protest you for having sideskirts on? :P

EDIT: Keep in mind, that was sarcasm. You know I <3 you Mike. ;)

TeamRX8 10-31-2013 10:48 AM

That and the non-factory front bumper cover :rolleyes:

Zelse 10-31-2013 11:10 AM

I'll give him credit for that he at least changes that to stock bumper on race days... :)

TopGear8 10-31-2013 11:35 AM

Oh I know, but it looks soo much better with the sides on! :)

Agreed! A whole lotta go and a little bit of show should be part of AutoX.

Zelse 10-31-2013 12:27 PM

Honestly, I'll be interested to see how it looks with front aero and the side skirts. Will be very interested.

what's next up on the list?

TopGear8 10-31-2013 12:45 PM

Turbo.














































Wait no thats not right! Trying to decide which flywheel would be best for the money. Looked at BHR and ACT. And then removing the CAT and making the exhaust a little lighter.

Zelse 10-31-2013 12:48 PM

Haha, nice! I was like... where is the picture? Oh.. Cliff hanger.

I've had both and I liked the BHR one better personally. Saves almost an extra pound too, so why not? What clutch are you thinking? When this ACT one goes, I'm probably just going to get it again because it felt great.

TopGear8 10-31-2013 01:06 PM

Got a new Exedy clutch this year with the engine so I won't be changing that.

TeamRX8 10-31-2013 06:21 PM

Static weight in that increment is not an indicator of "better". Only the MOI matters.

edit: revised for accuracy

I thought you had a mini-clutch, or rather I assumed you were the one that snapped up the 5.5" clutch & flywheel that Eb sold about a year ago.

btw, a builder who recently balanced a Renesis rotating assy with Stage 1HD Exedy clutch and ACT Pro-lite FW using the supposedly-superior ACT counterweight told me it required more modification and addition of heavy metal to get balanced than the OE auto cw usually does, so much for added value ... ;)

audio system out

most emissions components out

interior torn apart
front bumper cover and undertray are off

Besides removing the cat..What else is there?


Yes i'm an idiot I know :)

TopGear8 11-03-2013 08:27 PM

Also with the update/backdate between S1 and S2. Does that mean the S2 R3 sides and front bumper would be legal on my car...?

TeamRX8 11-04-2013 12:46 AM

Yes, could catch, but you will need to change more than the front bumper only

Showboater ego doesn't make you an idiot:stickpoke

Remove cat
Remove air pump and valve/pipe
Remove evap system & controls
CEL & DTCs don't matter
Aftermarket ECU system

TopGear8 11-04-2013 11:17 AM

Thanks Mark!

FTD this weekend over some pretty quick cars, Jinx Jordan's SMF civic, Jadrice Toussaint's BOSS ESP stang.. DSP is fun!

Might have to check this since it likely might mean drilling holes for the side skirts that otherwise were not provided from the factory on an S1 chassis. You can't make modificatons for fitment and there may even be a question about having to run a full R3 conversion except the allowed modifications per the update /backdate wording. It 's not loose and free as some people look at it sometimes.
