    2014 Event #8 recap

    The final event of the season began with Josh taking a lead on the first run. Unfortunately for him, he was driving too aggressively and spun on his second run, putting him some 6 seconds back. We went back and forth the rest of the AM, but he couldn't claw back much time from his mistake, and I had a decent lead at lunch time. Turbojosh decided to sit this one out, so when our PM runs came around Josh decided to do some hooning and see how much he could drift, since he didn't have much of a chance at winning. I pretty much just kept doing what I always do and laid down more fast times. In fact, I didn't hit a single cone all day, marking at least the second time this season where that happened, and was again the fastest 2wd car at the event!

    And with that, I won 5 consecutive events and had a decisive season victory! There were times, specifically in the 2013 season, where I was really fed up with this car, and was kicking myself for not getting the default E30. But with some work and choice mods (bigger sway bars, proper rally tires, a working O2 sensor...) the car really came together and now I'm totally in love with it! I still want to mod it more, but it's really doing quite well, all things considered. But rest assured, there is more to come!

    So I finally put on the proper windshield banner...








    Oh, and to make the weekend even worse for Josh, his ramps decided to slip off when he was putting his car on his fancy rich-boy trailer. Naturally, I declined to help and instead took pictures while pointing and laughing.







    Here's a pic of Jeremy's STi, aka the cone killer. And bumper killer. This was the first event where he didn't rip it off at some point. I think some sort of bet was involved.



    Here's a pic of the previously mentioned FC RX7 driven by Shawn and Katie. It's pretty much stock, but damn does it seem to effortlessly connect corners and drift like it's a job. It's a complete POS (it requires bump start to start and can't hold an idle without a foot on the gas), but it's totally awesome and embodies rally-x spirit.



    Here's Matt's constant-FTD Impreza with a EG33 3.3 F6 from an old SVX. This thing is just stupid fast, and sounds incredible. I will never be this fast.



    Results!

    And video! I missed recording my fastest time in the PM, but it doesn't really matter....



    Thanks to everyone for the help with the car this season! Thanks to Josh for letting me co-drive his 318 when the E28 broke (coolant hose burst, rear spring perch broke)! I'm pretty sure with my win I have used up all goodwill, and if something breaks in the future I will be on my own. Thanks to Patrick for letting me store the car at his place while I waited on Bilstein to send me new circlips, and for helping out with getting the car back together!

      I'm posting this here for later, in the hopes someone can comment on its fitment to my SETA E28 (it's listed for E30 ETAs with dual-mass flywheels).

      JB Lightweight flywheel


      Oh, and I'm parking this here in case I forget: IE brass clutch pivot pin, $20

        Nice!! That pivot pin looks like a no brainer if you have things apart already.

          why not just find a single-mass B25 flywheel? I would assume that would work for yours. Could always have it milled down for a hell of a lot less cash than the JB.

            I've considered that, but I think there's a problem with different crank sensor locations or something. I should probably look into it again.

              lol....nothing to lose there, and with the film crew from Velocity channel filming all the runs, I wanted to showboat sideways as much as possible. Would have been nice to win the final event, but the real goal was to drive over the limit and see how far I could hold it.

              Nick is being nice though just saying that I spun. To be precise, I spun on the last corner and came to a stop within inches of the finish line pressure tube and cone. Another foot and my time would have been wicked fast, going through finish backwards lol.

              With any luck, we'll get on TV at some points :)

                So....early word is that the new SCCA rallysprint will require weld-in cages, but will have much more lax requirements than Rally America about the cage construction and design (e.g. If you have a weld-in cage made of DOM steel, it's probably going to be legal).

                hint, hint.....

                  Pretty sure the SETA has the crank sensor on the front pulley like the "i" motors and most M5x motors. should be pretty easy to confirm just looking at it.

                    Well I got lucky browsing Craigslist last week and got the deal of the century. $2400 worth of Hoosier A6 245/40/17 rubber for $300, barely used. Also, a brand new (but expired....don't care) and a used 6 point harness for $50! I've got rubber for the next 4 years! Even though it's for my other car, I couldn't help but post it up in here. The harnesses WILL be used on the E28 though. I'm tired of my old crappy style harness lock.

                        With the 2015 season right around the corner, it's time to start furiously looking for parts to freshen this thing up and get it ready. The first thing to arrive was a used single mass M20B25 flywheel and clutch. There's no way we were going to spend $800+ on a lightweight aluminum flywheel/clutch combo, but with a 27.5 pound flywheel, something had to be done. After seeing rather high prices on the forums, I spent some time searching on car-parts.com and found one hell of a sweet deal. I found a junkyard that had pulled them out of a car and I was able to get them for only $85 (shipped)! From what I've seen, the "i" flywheel weighs about 18 pounds, which is rather substantial reduction from the stock dual mass unit.

                        It looks like it had been sitting around for a while, and there was some surface rust buildup on the flywheel and pressure plate. I cleaned them up a bit with a scotch brite pad, and I'm thinking they look good enough to throw in the car, but I'm no expert. Does anyone think I need to get the flywheel resurfaced, or need a new disk? Since it all came out of the same car, I figure there's no reason why I can't just slap it in mine and go. There appears to be enough material left on the disk. Let me know if you think otherwise!

                        Clutch disk:


                        Close-up of depth:


                        At least it's a Sachs!


                        Flywheel before:


                        And after:


                        Pressure plate before:


                        And after:


                        A big happy family


                        Obviously, I'm going to have to spend a fair amount of money on the little things:
                        -Throw out bearing
                        -"i" flywheel bolts
                        -Pilot bearing
                        -Brass pivot pin
                        -Clutch fork, spring
                        -Amsoil fluid
                        -Seals, Etc

                        I can reuse the bolts holding the pressure plate to the flywheel, right?

                        But even so, I'm hoping to get this installed for less than $200. I'm really hoping that shaving 10 pounds of rotating mass from the motor will really wake this thing up, but who knows.

                        More coming soon!

                          I've always been rather disappointed with the brakes on this car. Driving Josh's 318 really drove the point home, as his car seems to stop in about half the distance my car does, and without ABS. Granted, his car weighs 500+ pounds less than mine, but still, my brakes suck. But hey, the E28 was build with 14" wheels stock, so there isn't a ton of room in there for decent sized brakes. Well, the smallest wheels we have are 15s, which meant we could run the E34 brakes without a problem. I picked up a set of used calipers for $50, a pair of Brembo rotors for $50, and OEM Jurid pads for $50. So for about $150, I'm anticipating much improved braking! I went with the OEM pads because my requirements are to get maximum cold braking bite, with no regard for fade or dust. It sounds like the Hawk HPS that I think are on there now need a tad more heat in them before they bite, and we never build up any heat in the rotors during a run, so I figured OEM pads would be a good choice, but we shall see.

                          Oh, and I got new shoes for the e-brake to qualify for free shipping since I'm pretty sure mine are shot.

                          Obligatory pics:

                            According to my scale, the B25 flywheel weighs 18.8 pounds....

                                Nice, and well-deserved. Probably THE best-set-up Maxima/i30 out there, period.

                                Hey, I didn't get a plug as the one who got you started on autocross? ;)
