So, the day after we get the last of the fuel work finished, I get the Laser on a long on-ramp, and decide to mash the gas. Run second out to 7500 RPM, keep the gas planted, hit the clutch, hear the NLTS popping, smack it into third, drop the clutch, and get sucked back into the seat as it pulls forward again. Run the gear out to the top of third (pay no attention to how fast that means I was going), keep the gas planted while pushing down the clutch, hear that comforting "pop-pop-pop" of the lowered NLTS rev limiter, pull down to fourth, and pop the clutch out again, to the sound of the poor engine revving itself to the moon.
I caught second gear by mistake. Whoops.
Now technically, I shifted at 7500 RPM. However, thanks to the wonder of NLTS, my mid-shift RPM would have dropped to about 6000 RPM. With a third gear ratio of 1.000 (how convenient!) and a second gear ratio of 1.581, the engine was mechanically forced to spin at about 9486 RPM for a second, before I managed to get the clutch back in. (For more information on DSM gear ratios, see Tom Stangl's excellent VFAQ entry on the subject.)
Could have been worse; a second to first mis-shift would have netted over 10,000 RPM, which almost certainly would have caused a bit of valve float and head damage. However, thanks to the upgraded springs and retainers in the well-built head from Mitch, along with stock cams for a mild ramp profile, there doesn't appear to be any damage at all; timing is dead on, no untoward noise, and the car drove and pulled exactly like it should. However, later that night, we heard a bit of clattering from the bell-housing area, which we initially thought might have been a flywheel bolt backing out (a common problem with mis-shifts and other high-RPM misadventures).
So, after having just gotten the car back on the road, out comes the transmission; checked the flywheel bolts, and all are holding tight, so we have no idea what might have been causing that noise. The upshot is that we had a chance to check the condition of the clutch after a bit over 20,000 very hard miles (Erica taught herself to drive a stick on this clutch, and I've put a ton of drag passes and autocross events on it). The disc, surprisingly, was in amazing shape; the pressure plate and flywheel friction surface were showing a bit of heat-spotting, though. One interesting thing that I never noticed on the 2600 we put in the Eclipse: the hub and center section of the disc had blued from the heat.
Anyway, we just need to lift the transmission back into the, car, slap everything back together, and hope that whatever was rattling was taken care of during the disassembly. Whee.
It seems like I should give a quick status update for the Laser, since we've been pretty busy with it over the last couple of weeks. We've been playing catch-up; all the stuff that's been taking up room on the shelf with the plan to "eventually" put it on the Laser is now off the shelf and on the car. We finally got the rear Konis installed last week, and replaced the rear pads and rotors while we were at it; that required me finally getting off my ass and drilling out the seized lugnut on the driver's-side back wheel, and pressing a new one in. One new wheel stud, two new rotors, two new sets of pads, and a new set of lugnuts later, and the car was back up and running, with the rear shocks set at 3/4 stiff.
But, since I can't leave well enough alone, I found a good deal on a Buschur-modified SX fuel pressure regulator (basically, it's an SX FPR, but with a new machined base that bolts directly to the stock fuel rail, making installation a snap). I got that installed in an evening, along with a fuel pressure gauge, and after getting hose-off pressure dialed in at 37.5 psi, the car has never idled so well. I suspect some of the problems we've been having with idle quality may have been related to a very small leak I noticed around the OEM fuel pressure regulator, and possibly just an over-the-hill OEM FPR.
Finally, this weekend, I ripped the OEM fuel pump out, and installed the "Supra" Denso pump that's been sitting on my shelf forever, since I had originally planned on installing it in the 2g (and the plans there have changed somewhat dramatically, so we decided to hand it down to the 1g). In the process, I managed to snap off the two wires for the level sender and the idiot light right at the connector on the sending unit, which required me to whip up a rather ugly, but sealed, replacement for them. Wiring around fuel is something I've decided I don't like very much. ;-) I also took the time to run a 30A-fused circuit from the battery through a relay to the pump, to make sure it gets all the voltage it needs to perform properly.
All that's left is to get some of the interior back in the car (I can't stand sloppy wiring installs, so out came the interior panels to run the new wiring tucked in neatly) and swap out the front lugs for the new ones that hopefully won't crack quite as easily as the last pair did. For anyone who reads this: if you absolutely must buy Gorilla "tuner" lugs for whatever reason, replace them as soon as they start showing any sign of rust, or you're going to find yourself in the same situation as me. Better would be to find a set of lugs that are tightened with a proper socket, rather than a hex key inside a thin-walled lug, that will crack eventually after enough removals and corrosion.
Now, I just need to talk Erica into a bigger turbo. ;-)
So if you've been following these Laser blog postings at all, you might notice that there's a very small increase in the milage on the car since February. Sometime a few months back, we started having yet more transfer case issues: specifically, the yoke was leaking. We went a few rounds with the JBWeld, and finally got that sealed up. However, in my infinite wisdom, I decided to swap on the 2g downpipe that I had lying around from my car, to give the Laser a bit more go, thinking that the cat that had been modified to fit my old catback would mate up just fine to the stock exhaust on the Laser. Wrong. After going a few rounds with trying to weld up a new flange to the stock catback, I finally gave up and we ordered a shiny new 3" Megan Racing catback off of eBay, and picked up a new VRS catalytic converter from DSMotorsport.
A few installation notes: first, the Megan catback only came with gaskets for assembly, not for installation (apparently, you get the gasket for mating to the cat-eliminator downpipe they sell when you buy the downpipe), and the VRS cat was missing the promised gaskets as well. DSMotorsport sent out a couple to replace the missing ones in record time, kudos to them. Next, if you're planning on mating an RNR downpipe for a 2g to a VRS cat, be prepared to drill a couple of extra holes in the exit flange; RNR used a much larger flange, which actually worked out pretty well, because the downpipe could still be mounted on a 2g now. Finally, the tip of the Megan catback sits very close to the rear bumper cover; we're considering getting some longer rear exhaust hangars, since large bumps seem to give it a pretty decent rattle. (Actually getting around to installing the rear shocks would probably help too, or installing polyeurethane exhaust hangars instead of the 100,000 mile 13-year-old stock hangars.)
The catback came with an insert to reduce the noise, and it works like a champ; with the insert in place, the car sounds like stock. Take it out, and it's a typical fairly loud 3" DSM exhaust. Overall, fitment was just about perfect, the welds looked good, and there's only one bend in the entire thing. I'm pretty happy with it so far.
One final difference seen, as a side note: the car is currently running 17psi of boost, which has always meant it spiked to 20psi, then quickly settled back down to 17psi and stayed there. Since adding the exhaust, it's not nearly as stable as it used to be; we'll initially spike to 20psi, drop down to 17, then fluctuate the remainder of the pull between 17 and 20 psi. No significant creep, but definitely the early signs of it setting in. After seeing what a difference a new wastegate actuator made on a friend's car, I'm suspecting that flutter is likely due to a weak OEM spring coupled with 13 years of duty, but it's really not a problem right now, so I'm leaving it as a mental note to look into later.
So we wimped out, and just packed the old carrier bearings with silicone and popped the new-to-us transfer case on the car. First impressions are extremely good; rather than bouncing, we get a ton of wheelspin at launch (which probably has a bit to do with both the stiffer front suspension and the new motor mounts). We also don't get any driveshaft thump, so the main problem we were after is taken care of. With any luck, that was the only remaining problem causing us to eat through transfer cases, and we'll be good for a while.
Before taking it back out, I set the front suspension to a half-turn from full hard (these are Koni yellows), and it's definitely too hard for the street, although it sticks very nicely up front. ;-) I'll need to back that down a bit (when we drove to Norwalk last year for the Shootout, it was set to almost full soft). I also need to get the rears on the car, but we need to decide what to set them for, since they're not adjustable once they're on the car. Foo.
So, when we last saw the Laser on the road, we screwed another transfer case due to what we believe was faulty carrier bearings. So, five months later, we finally ordered the parts we need to do the carrier bearing replacement, and last night I finally dropped the exhaust and driveshaft. What a PITA; I didn't originally think I'd need to drop the exhaust, but the only way to get the transfer case and driveshaft down was by undoing almost every attachment on it, so it just ended up being easier to pull the whole thing. (Now to convince Erica to let me put a real exhaust on the car, rather than that POS back on.) Next up: see what's needed to get the bearings off, and the new ones on; it looks like we're basically going to have to take the entire driveshaft apart, so I'll have to keep my eyes open for parts that need replacement.
One fun thing I discovered when separating the shaft from the rearend: only three bolts holding the shaft to the rear differential, instead of four. Goddamnit, I keep finding stuff like that on this car; someone really enjoyed ghetto-rigging things on here. :-P Good thing I never launch the car hard or anything, right? Grr.
I've been remiss in updating this. The car is home, everything has been taken care of with Mitch, Joe, and Jon, and the car is running like a champ. Actually, I've autocrossed with it twice now; there's a couple of rough edges (brakes, specifically), but the tranny is performing as it should. We've also installed the K&N FIPK kit (it's actually for a non-turbo, but we got a really good deal on it, and it was easy enough to adapt to Erica's car), and it's running with the wheels and tires from the Eclipse.
Sunday was Laser-day. Thanks to a friend of mine back in Canada (Hi, Rudi!), we managed to obtain a set of "Canadian" seatbelts for the Laser. The stock seatbelts are the automatic strangulators that the early '90s foisted on the American automotive market; I couldn't get used to them, kept getting caught on the automatic belt, and kept forgetting the lap belt. So, we now have a (much lighter) set of manual belts on the front seats, thanks to the handy VFAQ put together by Tom Stangl, Kyle Zingg, and John Evert. I haven't weighed the automatic parts that we pulled, but they've got to be in the neighborhood of 20lbs or so.
We also installed a set of shifter bushings from Mach V. Install was pretty much the same as it was for the Eclipse, but it made a huge difference in the tactile feel of the shifter; shifts have a distinct "ka-chunk" sound to them now, and transmission activity can be felt clearly. Definitely worth the money for what you get out of it.
Still to-do: I'm pondering pulling the boost controller and gauges from my car and installing them in the Laser, to get Erica up to at least 15psi safely. We also have a new turbo compressor outlet elbow that needs to go on, a 2g O2 housing (from my car), and a 2g throttle body elbow (also from my car) ready to go on, as soon as we whip up some replacement intercooler piping. Hopefully we can get most of this done before June 1, since we're planning on making a trip to Rt. 66 that night to see how it does (and hopefully beat a friend of mine from work in a modified RSX-S *grin*).
So, the car is still sitting at the shop. Joe at Elite and Mitch from Engintecs have been great through this whole thing; Joe and his guys have been more than happy to jump up and tackle jobs that I'd never expect them to take (specifically, pulling and replacing the entire clutch and brake pedal assembly), and Mitch has been a life-saver coordinating things, helping Joe's guys out when they weren't sure where something on a DSM went, and doing fabrication when the bushings ordered from another shop were out of spec. Jon and Ming at TRE have, so far, been taking pretty good care of us as part of the whole transmission rebuild, although I'm a little put off by their customer service and the difficulty we've had getting ahold of them in a timely manner.
Here's a quick run-down of the entire experience. We flipped a coin, and decided on TRE for our transmission rebuild (rather than John Shepherd). We contacted Mitch to see if he could recommend a shop that would pull the transmission for a reasonable rate (most of the local shops I'd talked to were asking an outrageous amount for work that I've done myself before; I know damn well it doesn't take 8 hours to pull a DSM tranny), and he suggested Elite, who happened to be in the same building he's in. In the mean time, we'd been ordering a number of pretty nice replacement parts for the car to go on at the same time. That's where the first problems popped up.
We ordered the ACT 2600 with street disc (XTSS) from Pro Street, and as always, it was shipped promptly and got here in fine shape. We'd also ordered a Fidanza aluminum flywheel from Slowboy, and a billet clutch fork from Taboo. Slowboy mixed up our order and shipped an ACT flywheel instead, which cost us a couple of weeks waiting for the return and reship. Taboo apparently had a CNC mill failure, and couldn't produce a clutch fork for us until a good week or two more, so I ended up picking up another one from a local DSM owner instead (the one from Taboo arrived the next day, of course). Neither shop was incredibly good about responding to emails (or, in the case of Slowboy, voice mails; in Taboo's case, you'll note that there ISN'T any other way to contact Martin over there other than through email). Other incidentals included 3 quarts of Penzoil Synchromesh and a new clutch fork fulcrum ball from RRE.
So, having finally gotten all the parts together, we dropped them and the car off with Elite to have the transmission pulled. Mitch was heading over to Kalamazoo, MI to talk with Jon at TRE anyway, so he volunteered to take the tranny with him (saving us $75 in shipping or so, woo!). TRE took it, and did their magic with it for a couple of weeks. They proved to be a bit difficult to get ahold of; they seem to have intermittant problems with their phone line giving a busy signal over entire days or weekends, and so when Mitch again volunteered to go out there to pick up the transmission when it was done (he was going to be in Michigan anyway, but it would have been quite a bit out of his way), we couldn't reach Jon to ensure that the tranny would be there when he arrived. *sigh* So, we said to hell with it, and had him ship it back to the shop, which he did...to the wrong address. A couple of days of confusion later, the tranny arrives at Elite, and they install the newly built transmission, clutch, flywheel, fork, pivot ball, and a 1/16" shim behind the ball to get the engagement point a little bit closer to where it should be.
After about an hour of futzing with the clutch master cylinder adjustment rod, Mitch comes up with a few conclusions: first, the master and slave cylinders are shot (which doesn't come as much of a surprise). Second, the clutch pedal assembly is shot (which did come as a surprise). Joe does the slave and master replacement (and got me a heck of a deal on the parts, I might add), and I order a set of bushings from Taboo. Again, I hear nothing from him; after I prod him a bit with an email, Martin from Taboo tells me that he's having problems getting the oil-infused bronze he uses in some of the bushings, and the batch he has now isn't suitable for delivery because he learned that the measurements on them didn't fit most of the cars he'd shipped them out to. So, a week and a half goes by, and we finally get a set of bushings from him (without word that they'd been shipped, of course).
The bushings didn't fit. The brake pedal bushings fit like a glove, but the clutch pedal bushings were out of spec by quite a bit. Mitch managed to fabricate something up that worked, and Joe's folks put everything back together. So, finally, the car is back in one piece, and drivable. Joe takes it out for a spin, notes that it pulls pretty good for a basically stock engine (although not even close on the drivetrain at this point), and when he pulls back into the yard, notices (of course) a leak coming from between the transmission and the transfer case.
They popped the transfer case away a bit, and saw that there was a good bit of fluid leaking from the output shaft seal on the transmission. The BRAND NEW SEAL on the FRESHLY REBUILT TRANSMISSION. *sigh*
So, that's where the story ends for now. Jon, Mitch, and Joe are going back and forth to see who's going to foot the bill for the work that obviously needs to be done now, and barring anything else happening, the Laser should be back on the road in a few days.
