  1. Yeah. 7 gallons just won't do it. If you're driving hard, you'll burn through that in no time in a turbo engine. I use about 4 gallons of fuel during a 15-20min track session. Turbo motors are thirsty. I'd like more capacity than the 10 gallon stock fuel tank, but it works well enough. My set up is just a Z31 fuel pump assembly grafted into the stock tank. Sadly, I put mine in the middle of the tank instead of off to the left side like many SR20 guys do. The Z31 has hard lines, so AN fittings have been used to adapt to my fuel lines. Standard Walboro 255lph pump. I think this is for an S13, but it might be a DSM unit. I don't recall. This is the "fuel bowl" from the Z31. It helps reduce fuel slosh and helps to keep the fuel pump submerged in fuel.
  2. Some of those suspension parts look familiar 😉
  3. I have a Z31 long nose R200 in my car with CVs. I used a Tomei 1.5 LSD from the S13 short nose. The stock Z31 splined axles fit just fine. They are the same as the S13 "non-lsd" axle stubs for size and spline count. I believe the stock LSD axles are different. The rest of my setup is basically irrelevant since I'm using Pathfinder axle shafts and I welded in the Z31 hub carrier for brakes and 5-lug adaption.
  4. Yeah. It was basically the first cone on the slalom. Boost hit right as I was starting to turn. I didn't even bother trying to save it other than to keep it out of the wall and off of their shins ðŸĪŠ
  5. It's been quite a while since I've updated. I missed a summer trip due to some wiring issues, but did a 1000+ mile round trip to Datsunville in October. not much has changed, but I have some things in the works. For now, here is some autocross video from last weekend including a bad spin. I need more tire. And more skill 😋 LVRSCCA Round 5
  6. Here's the autocross video 🙂
  7. I just returned from a 1,907 mile road trip. Before leaving, I made a few "improvements" to the car. The first was the previously mentioned cruise control. It was not as simple as expected. The directions are pretty basic and aren't quite accurate. I ended up finding an alternate tach signal than the directions listed and had to adjust the signal to compensate beyond what the directions list. That being said, it works great and I think it actually improved my fuel mileage. I mounted the unit in the cowl area using rubber mounts to isolate any mechanical noise that might get transmitted into the car. The control panel is mounted inside of my center console to keep it out of eyesight. The next item was more of a safety thing. I've wanted to add a high mount brake light for while. The 510 is by no means the smallest car, but soccer moms still have trouble seeing it. I got my unit from an early 90s Civic sedan. The rear window radius is close enough. I had to create a mount to lift it up and have something to attach it to my rear shelf panel. While I was in Colorado, I also attended a local Solo autocross event. I'll have some video of that up soon as well.
  8. Here's some video of the car on the dyno from October. It made 285hp at 10psi and 345hp at 14psi on a Garrett hybrid GT3067R.
  9. I took the plunge in my search for cruise control. I just ordered an Audiovox CCS-100 from eBay (fingers crossed). It's a "sealed vintage unit" for $170 shipped. Better than the $230+ places are asking for new units or the Rostra units out there. I'm hoping it works on a turbo car. I'll get a chance to find out while the world is in quarantine and hopefully this summer on a drive to the NW at Powerland if it's still going on.
  10. Saturday I got the car dialed in on the new Silver Mine suspension and got an official weight for the car. Sadly, all that suspension tuning didn't turn into fast times at autocross on Sunday. I'm still figuring out how to drive and it's definitely tail happy at the limit. Turn in seemed better and the car set better on turn in, so something is working right. Now I just need to tune the nut behind the wheel. Rave reviews were given about the Futofab front control arms and the Byron's brackets out back. The tuner is familiar with the 510 and does set up work for major race teams and manufacturers, so I'd take his word on it. As far as the Silver Mine coilovers, they seem to work as intended. I think the front springs being 4k might be a bit soft, but the shock adjustment is in the middle, so I'm sure I can stiffen it up a bit. The rears are 5k and we raised the car about 1/2"+ from the Specialty Engineering springs I had previously. I'll keep driving it to provide more feedback. I might try to do the National Solo event in 3 weeks to get more seat time. Sadly I don't have any in car video from the event, as the video files seemed to have been corrupted or something.
  11. Here's a video that's way too long about my Silver Mine Motorsports coilover install. I'll update with another video in about 2 weeks with my feedback and impressions from the next autocross event on March 8th.
  12. Autocross February 9, 2020. The car still had understeer due to lack of front end suspension travel. I have changed suspension set ups to the Silver Mine Motorsports since this event. I'm getting an alignment this week and the next event is soon, so I'll get a chance to provide some feedback.
  13. Here's a short video of me on the highway coming home from autocross. I found myself without traction rolling into 3rd gear.
  14. After that last autocross, I started shopping for new suspension parts. I've discovered that my front end is running out of suspension travel and bottoming out giving me understeer with the grip level I'm currently experiencing. My current set up is full length S12 struts with stock 280Z KYB inserts and T3 coil overs up front. Out back is Specialty Engineering springs and KYB shocks (probably Camero units). I would love to run Troy Ermish's stuff, but I think my set up is quite different from what he deals with. He's a smart guy and I'm sure he can cook something up, but I've gone another route. For the price, I'm not sure I can do better. I just purchased a complete set of coilovers from Silver Mine Motorsports. The fronts are adjustable for height, spring preload, and dampening. The rears are just height and spring preload adjustable. My biggest selling point is the modularity of the units. Several other companies have similar styles of coilovers and I'm sure they all use the same threaded tubes making it easy to run someone else's stuff in the future if the need arises. But for $800 shipped for a set of 4, it's tough to argue against it. I haven't seen too many people running them, but a YouTuber I follow, CZero Media, runs them on his Z and likes them. My uses will be different than his, but there are several "sponsored racers" on the Silver Mine site, so they might work out okay. I'll update this thread when I put them together and give some initial feedback. The next autocross event is March 8th and I'll give them a full thrashing :-) I'll post a short video from last weekend's autocross soon. I only made 3 runs and left before the afternoon session due to weather. I finished mid pack and at least 3 seconds slower than I think I can run. Oh well.
  15. I didn't find anything I was liking, but I did find a cheap delrin "Rally Art" knob on Amazon. None of the inserts fit, so I made something work with a nylon bushing and a thread tap. I definitely want something more, but it does the job and looks better than the beat up original knob.
