  1. I'll see if any of the local guys selling parts have a 510 crossmember. Would be fun to at least compare them side by side and get some documentation going. I've often wondered if they were symmetrical enough to flip like that. Will definitely give that idea a good think once I get to that point. I am aware that at least some of the truck/suv KA's being rear sump and may also go that route. The sexy option would be dry sump, but I don't think I can justify the cost on that lol. The engine in question is "allegedly" an ex race engine out of a '91 240sx. "Allegedly" it's pushing like 220 at the crank. I'll believe it when I see it, the guy is a friend of mine and is certainly a believer of not letting facts get in the way of a good story; but the price is good whether it's a built motor or a paperweight that I have to rebuild.
    Gauge cluster was in fantastic shape and packaged well!
  2. It's looking sweet dude! Saw it pop up on my local craigslist a few months ago, glad to see you kept her. (and/or someone was running a scam lmao) Hmu if you're gonna do any cars and coffee events in/around the bay would love to see more than one 610 in one place!
  3. So after rebuilding my rear axles, I took the car out for another track day last week at Thunderhill - West. I've come up with a whole 'nother laundry list of things I plan to do in the future. She needs more front camber something fierce. I'll be ordering a bunch of front suspension stuff from Troy Ermish to get that corrected. As she sits right now, you'd get the slightest hint of rotation and then the rear tires would catch and straighten you back out, strange sensation in a RWD car. Also track driving on 680TR tires is a riot, kinda like piloting a bar of soap in a bathtub. Some photos that illustrate the camber issues quite well. lol After the track day my driveshaft u-joints have decided they hate my guts. So those get replaced as soon as I find the gumption to do so. I have some photos to share regarding the axle shaft rebuild so I'll probably do a post on all of that in one go. I've recently got a lead on a nice KA24DE with some goodies to swap in. I'd like to be able to go back to the L18 later in life so I'm planning to either track down a spare crossmember or make my own custom one so as to preserve the OE member. I got looking at Maddat's stuff in Ozland and it looks like the 510 and 610 crossmembers are pretty substantially different. So that makes sourcing a spare hard, maybe a custom crossmember will be the way to go. Unless I'm misunderstanding something here, would love to be corrected. lol If(big if) I build a custom crossmember I'll likely keep all my jigs and drawings for them, build some more for any members who're interested. I've already made the cuts in the tunnel to adapt the KA transmission a few years back (Assuming the KA and CA transmissions are the same length, I'm like 90% sure they are.) and my driveshaft has also been modified to suit. I'll be throwing in a more efficient radiator and a mega squirt controller with this. I'm pretty sure these will have all my bases covered. Though that kind of power will also require better brakes, so it may be time to do the 280ZX strut swap that I've been putting off.... I dun wanna. For no particular reason mind you. So tl;dr Suspension mods and brake mods incoming. Then a potential KA swap maybe early to mid next year.
  4. I would love to have that gauge cluster, do you have any closer up photos of it?
  5. That is a great question! I put back whatever I took off; and it's been long enough I don't recall. If the stock bump stops are the kind that ride on the shaft of the strut insert, then I guess mine had rotted off and I'm not running any at the moment. lol If they're attached to the strut top hat, then I'm running whatever rubber was still left. I went out last night and finished the install of my modified alternator bracket, and threw some stickers on the car to help improve the smiles per gallon even further. Unfortunately my partner's lease on this hangar expires this week, so Anita is going back to a dirt driveway. Probably won't get a lot of work done until we get into a different building. (I just hate dirt so much.) The last photo is most of the old parts that got replaced over the last year minus a battery, multiple brake boosters and a second alternator. Feels like a lot less with it laid out like that. I've got some New Year's resolutions that kinda run parallel with this car so there should be some more neat stuff this year.
  6. So TL:DR springs are fine; and don't bottom out, at least they don't bottom out on the Corkscrew at Laguna, and that's good enough for me. lol I ended up using 280ZX cartridges and machined out a Delrin insert to take up the extra space in the shock body. The travel length between the two was the damn near the same so I wasn't concerned about it. I've got photos for this and all the other ""mods" and I'll get them uploaded soon™. I swapped in an internally regulated alternator from a 200sx as my regulator bit the dust two days before Laguna, and then spent the rest of my free time tidying and prettying the car up in general. I sprung an oil leak from the fuel pump base at the event. Not sure where from, but I've already replaced it with a new one, I'll do an autopsy on the old pump whenever I next get bored(Ha!). Decided to drill out my alternator bracket to allow for M10 hardware since the M8 stuff has been stripped for as long as I've had the car. I had gotten reeeeal tired of adjusting the alternator every couple hundred miles, now we're golden. I've added to my future list; so many rubber bushings and some adjustable suspension components, both to fix the toe in the rear and to get the front camber under control. But those are a couple months down the road if not a couple years. In the meantime, I took the car to Laguna, it was a riot. Here are photos and a really crappy video from it. (Including a crunchy missed shift because I am bad.) https://www.youtube.com/watch?v=KfsFHVRD_OI&t=40s
  7. I found an individual selling some 280ZX struts already converted to coil overs(which I know I said I wouldn't do anytime soon), reinforced and setup for rally racing. They're very reasonably priced, so it seems like a no-brainer. I'll need brakes, bearings and even more springs, but what the hell, if the price is right, right? Sent them a message, fingers crossed. Does anyone know if the pre-fabbed 510 Rollbars also fit in the 610? A lot of the companies that build them list them as 510, 610, 710. And while I'm hopeful, I'm also skeptical.
  8. Well phooey. I take back everything I said about rebuilding these struts. It appears to me that someone has been in them before me and replaced the good stuff with inserts. Sooooo, idk what I'm gonna do right now. Between this and my daily deciding it needs all of the repairs my finances are shot, so I guess I'll just leave her on jack-stands for now... I guess I'm cutting these guys down and ordering some 280zx inserts in a couple paychecks. Judging from the numbers I've found I should only have to cut it down by around 1 1/2", but I'll get the inserts and verify.
  9. Yeah, They're Kings from Oz. They have a fairly high rate to them so they compress a lot less than the stock springs do. It's an advertised 30mm drop and the rears measured out at about 25mm, so I'm not too worried about bottoming out. As I said earlier, I might do 280zx struts in the future, but it's just not in the current plans.
  10. Springs got here last week so I started putting them in last weekend. Rears went in with minimal problems, (Only rounded one nut, new one ordered.) Here it is with the rears installed and set back down on the ground. It's minimal, but I wasn't looking for much. Fronts were slightly more interesting. Someone in the past apparently lost one of the lower strut bolts and thought this was a good idea: Through some miracle of fate the threads are undamaged. So I ordered a NOS bolt and a gland nut wrench (I thought I had one but was unable to locate it, also didn't have the will to make my own.) Under the boots the front shocks are clean and dry, so I have high hopes I can replace the oil and call it a day this weekend once the tool and bolts are here. I also ordered ball joints. These are extra floppy.... And lastly have a goofy, not quite artistic picture of all the tools and stuff: I plan to replace all the bushings sometime over the winter and will probably go through and repaint all the suspension components just so they look less crusty. But at least right now I want the car drivable for a thing next week. We'll see how that goes. Thank you for the thorough information. I'll probably do this upgrade eventually, but at least for now while (crossing my fingers) the struts look easily rebuildable I'll stick with the stock stuff. I have no good explanation for wanting to avoid adjustable coil-overs aside from I just don't want them on this car at this point in time. lol
  11. Per the rules yeah. But seeing as these brakes could hold up to what I'm assuming was fairly hard and serious racing, I'm of the opinion something is screwy with mine. Rubbers and adjustments are cheap, especially since I already have new lines, just haven't installed them yet. I'll try that first Originally I was going to do the 280zx strut/brake swap and I still may in the future. Iirc you keep the 610 tops and springs but the 280zx strut bodies are longer and you end up having to move the spring perch or am I misremembering that? But at least for right now rebuilding and re-springing the struts I have should be fine. Didn't know about the larger bearings though. That's good information to mull over.
  12. Just a small update from my time working on the car yesterday. Fixed an oil leak from the fuel pump base, realized I ordered a sedan interior door handle and not a coupe interior door handle. And found my check valve on the brake booster to be working fine, so I guess the cheap a/m unit is cheaply made. Shocking, I know. After doing some more research on brakes, it is my understanding that the old SCCA ITC cars kept the stock brakes. I'll toy around with what I've got and see what I can do, the brake system is obviously not in tip-top shape with the failures I've had, but even when the booster was working the car just felt massively under-braked to me. The plan this week and next is to re-adjust the rear drums, see about doing some corrosion mitigation on the front, replace all the rubber lines and flush the system. We'll see how they feel after that, if I'm not 100% confident in them she's getting a Wilwood kit. Also as a side note, after talking to one of our hangar neighbors who used to race 510's I've got another small list of things to tack on between now and October. Still retaining the stock seats for street driving and meets, but I will be swapping the seats out whenever it goes to the track for something with less of a propensity to break spines.
  13. I'll give it a shot, thanks!
  14. Can't be any worse than some of the old bucket trucks I drove in an earlier job! In all seriousness, I'd rather keep the booster, but replacing it every four to six months is gonna get old quick. I'll check the valve next time I'm down at the hangar, hopefully it's failed and a new booster and valve get me sorted for a longer period of time than last. I would assume being as old as these cars are and as cheaply made as the replacements are that they still use rubber diaphragms. I haven't taken either of the old ones apart to verify it was actually rot or a split seam. But I agree with you, in general rubber is the enemy.
