I'm 4 years running on solids and have never touched them except to measure clearance every spring, to find they haven't budged. The reason the old engines need adjustment id because they have adjusters that get out of wack easily. Don't let them old schoolers scare you away from solids, yes they were a odin first go around, after that your golden!!
The last couple sets of shims that I made were from O-1 tool steel that I heat treated to get a higher hardness than the stock ones (look at older posts in this thread for details). I used a surface grinder to get the smoothness I needed. The tool steel I used was 10mm drill rod, so I only had to part it off and grind. Real simple machining. I need a 3.44mm I believe (actual number written down at home). Largest factory shim is a 3.2mm. When I tested the hardness of the factory shims, it was fairly high (if I remember correctly, around 60 Rockwell c scale), so you need to use a tool steel to get a similar hardness, otherwise the high loads at rpm can distort the shim.compactfean wrote:What sizes do you need? I argued with my machine shop about this time and time again and they said they did the valve job right..... Bla bla bla. ended up using 10mm harley davidson shims and I found a company that sells sheets of .003” hardened steel and cut those into 10 mm rounds and put them under a couple of guides. Some of the harley shims we used the 3 step sharpener from, harbor freight to file the do to perfection but most, we were able to order to spec. My buddy isnys motor I just built, he opted to not buy any shims, to save money he hand ground and filed all 16 of them. Lol
The paint is actually damaged up top, and the bumpers were "touched up" very poorly, lol. A lot of runs! Yeah, the interior is pretty decent, so I was stoked! Got some OEM floor mats in it now, so I was able to can the crap ones in the picture.Hoffman5982 wrote:I'd look into having it re-cleared, unless the paint is actually damaged. Looks really good nonetheless. It's weird seeing a Zenki with a steering wheel that's not all fubar'ed from age.
It's pretty sweet. I also want to do it on drivetrain stuff, but need to get the things I need first, lol. Going to do a Z trans w/ adapter kit, and an OS giken 1.5 way eventually.Hijacker wrote:Oooh! WPC treatments. I'm considering that for a few drivetrain components.

I've been thinking about LS for awhile myself. I really got inspired to go with a bigger turbo with your video banging through gears, listening to the Korn track. Wanting to keep the SR because it keeps the car balanced and is a square engine. Got a red top bottom end I'm working on. Good luck to everybody working on their projects.2_Liter_Turbo wrote:91rb240c wrote:Great thread here, gives me hope for my project.

I thought about it many times as well (except LS variant, lol), but I stuck with it. Mainly because I have soo much time, effort, and of course money wrapped up in this engine. This will be my last go around if it doesn't work out though... ha ha. I'm hoping it does, and if so, I will continue upgrading the hell out of the motor! I'll always keep a 240 though, no matter what motor. I've just grown to love the cars.
Ha ha, awesome! I've been a long time Korn Fan. I don't music on my videos anymore due to the copyright stuff thoughLobo240sx wrote:I've been thinking about LS for awhile myself.
