    I've read its because of tight tolerances between the rod bearings and the crankshaft. The superfucking thick oil doesn't help matters.
  2. While doing some highway testing in the spring (very late to update this thread) I pulled over to richen up the mix for driving at 70-75. As I was making the adjustment I noticed this. Almost all the screws to the fuel bowl had rattled loose and fell out. the last one was barely on by a few threads. I tightened that one down and limped home. Now they all have blue loctite on them and I will definitely be keeping an eye on them constantly. Almost burned the car to the ground. I got very lucky on this one.

    I would of attempted it myself, but I didn't have the tools needed to do this and it would of taken me forever. The bearings are really bad. He had them in a baggy for me. There is alot of material gone. The new OEM bearings have that WPC coating added to them.

    The car is home. I'm impressed with GSR Motorsports. Greg was keeping me updated through the process by texting me pictures and stuff. They also found the leak that was causing the little puddle of oil under my car. The oil filter housing is leaking where it connects to the engine block. I'll order up the gasket and do that job the next time I change the oil.

    Well all the bearings I've seen come out of these engines look like this. So "normal" for a S65. The bearings I pulled out of my 50+ year old datsun looked brand new. So that doesn't seem typical for all engines, just this one. Glad I did it. Of course the internet was right. It's never wrong.

    FWIW, the car is at GSR Motorsports getting the rod bearings done.
  7. Haha! I just meant I've put on almost 20 lbs of muscle and the chest strap doesn't fit anymore. I still CrossFit my ass off. Lol
  8. I've got a used Simpson Hybrid Sport, size small, for sale. I've done too much crossfit and it simply doesn't fit anymore. It has the D rings and tethers. I have the box it came with. $200 Dave
  9. Pad knockback was really bad with stoptechs on my 350z. I switched to factory brembos and it lessened a bunch. Then I put in new front hubs and it all but went away. I ended up using pad knockback as a sign of worn hubs. YMMV.
  10. You were doing great. It felt like you were holding maintenance throttle a little longer than I thought was necessary. It felt like you were thinking you would run out of track on exit, and from my side of the car, it looked fine.
  11. Howdy, been a while since I've been here. I did a small change with large ramifications. When I bought the car I got new metering needles for the SU carbs. They were coded ADQ. There are 16 stations on the needles where you can measure/change the diameter. I read the ADQ was the best on the Datsun Roadster forum and they worked fine while the engine was old and beat up. With the new engine they limited my stroked 2 liter. I had them tuned for about 45 mph anything over that and it would go lean at cruising speeds. WOT was great though so I could gun it up to 80 or 90 but then as soon as I tried to maintain that speed I'd be around 16/1. Way too lean. So I ordered some new needles. I just took an educated guess and bought some ADM needles. They are roughly the same as the ADQ until you get further down the needle. I installed the new needles today and tuned the carbs to them. They worked out pretty darn good. Now that I have the A/F sensor I was able to tune the mixture very easily by just resting my phone on the car and rotating the dial until I got 14.7. I took the car out on its maiden voyage and everything looked ok on city streets so I decided to chance it and hop on the tollway. I got it up to about 65 (that's about 3500 rpm in 4th gear) and cruised there for a few miles. Everything looked pretty good! I was at about 15/1 on average so it was a little lean but not scary. It wasn't stumbling or anything. In fact it was very quiet. I also did a valve job this morning. That seemed to help smooth out the engine too. Anyway, it was all very promising. I will continue to tune it a little more. One thing I was able to do was lower the needle to help the idle not be so rich. I plan on moving the needle up just a nat's ass to see if that helps with the A/F. If not, I will put it back to the lower position and richen the mixture a little bit. If it all goes well, I won't be relegated to just driving on city streets, which means I can get out and do fun drives. I'm getting excited. To be continued....
  12. somewhere between 1 and 2. God I was awful. lol This is blue group.
  13. The brake pads that came with my E90 M3 must of been super thick because the brake pedal barely moved at all. I got nowhere near the gas pedal. I changed out the pads and now the h/t is much easier. I use the side of the foot btw.
