manimal Posted August 21 Share Posted August 21 Beautiful work! I'd love to see more pics of the rear diff cradle and what's going on around the transmission and the matching(I assume) front control arms. The driveline work to fit the Z31 parts and Z32 brakes is so clean! Are you doing all your machining on a 3 axis mill? Turned parts not withstanding. That Alodine coating looks really good. It's a nice compliment to the cadmium/yellow zinc fasteners and fits the vintage car vibe. I hadn't heard of that coating before, based on some youtube videos it looks pretty easy. I've got a few vintage bicycles where that would be the perfect color compliment. Dual is correct btw. I think the other poster didn't realize you meant dual exhaust.

MONZTER Posted August 25 Author Share Posted August 25 Ill Put some more pics of the diff mount/cradle and the trans mount. Yes, doing all my machining on a 3 axis using SolidCam. I buy the Aloding coating and the acid prep/wash from Aircraft Spruce. Its easy to do everything just has to be spotless clean and degreased. I designed and made this diff cradle so many years ago I had to dig up pics. Dont think anybody had something available back then This pic dates back to 2001, thats how long this project has been going. All the turned parts are done on a manual lathe and I did not have CNC back then so its all done on a manual mill as will. All 4130 steel, pretty light actually. Just a hobby so no hurry I guess Front diff mount is two OEM mounts cut in half and weled together, I integrated the solid mount into it as 1 pc. Here are some CAD pics of the mount. I actually have moved the engine back about 1 inch so I needed to make a new trans mount. Wanted something to go with the new design front motor mounts Ill show soon when I finish up the cross member. The bushings are from the outboard rear control arm urethane kit. I Its steel and aluminum contruction. I still need to put a finish on it. But I wont probably use it now as I am going to replace this S15 Trans with a Nismo 6 speed. So Ill have to modify the design and make some new parts. Front crossmember and Front suspension coming soon 1 Quote Link to comment Share on other sites More sharing options...
Derek Posted August 26 Share Posted August 26 Nothing more satisfying to me than designing something in CAD then walking out to the shop and implementing it. Great work.....As usual:) Quote Link to comment Share on other sites More sharing options...

Leon Posted August 29 Share Posted August 29 Wow, gorgeous work. Do you have more pics of that rear caliper adapter? Quote Link to comment Share on other sites More sharing options...

Here are some more pics Started with a backing plate from a Z32 Here is the CAD model where I got it all worked out for the proper spacing / fit, ect. Machined the parts from this CAD This is the first fit check. You can see how the rear hub bearing was modified for a 5 bolt Z31 turbo stub axle bearings and CV flange Just some final pics Quote Link to comment Share on other sites More sharing options...

Leon Posted August 31 Share Posted August 31 Rad, hats off to you! I've not seen a drum-in-hat park brake done on an S30 before, very clean. Did you 3d scan the z32 backplate and constituent parts? Quote Link to comment Share on other sites More sharing options...

Just did all the suspension and reverse engineering old school with calipers just measuring. It's all pretty simple stuff 1 Quote Link to comment Share on other sites More sharing options...

It's all pretty simple stuff I have a get down white light scanner and a lot of times unless it has some really complicated contours or boss locations it ends up being faster to do it either with calipers or I'll mount it up in the mill and probe out the needed data. But when I do need it I'm super glad I have it. Quote Link to comment Share on other sites More sharing options...

Thanks, I enjoy keeping up with your projects as well, nice work you are doing on the intakes. I machined this plenum years ago. Made from 2 halves and welded together. Hoping to one day run it.

MONZTER Posted September 11 Author Share Posted September 11 (edited) I finished up the front crossmember and motor mounts Started with a stock crossmember with the need for new engine mounting since I moved the engine in the chassis back about 1 inch. I extended and boxed in the existing upright Some grinding and blasting to clean it up 3 D printed mockup of a machined bracket I made to accept the moustache bar busings. I designed these years ago and have been in the NA car for 15 years. Worked well I machined this weld in bracket out of a solid chunk of steel because I wanted the details for the bolt holes and you could not do that with bent sheet metal. Stupid but fun. More soon Edited September 11 by MONZTER 2 Quote Link to comment Share on other sites More sharing options...
MONZTER Posted September 15 Author Share Posted September 15 More pis of it finished up The bottom plate was beat up a bit and bent from floor jacks. So I took off the old one by drilling out the spot welds. I then drew up the shape and had a new one laser cut. The center plate that is welded to this plate, I re-made it as well, but out of 304 stainless steel. This way I can leave it a brushed stainless finish after powder coating and it is a good place to use a floor jack. I then spot welded on the larger plate in the original locations I then tigged the seam between the spot welds Then tigged on the center stainless plate Then blasted the entire cross member and powder coated it in a super black semi gloss powder coat. Powder coated the motor mounts as well I always first do a primer powder coat that is sandable I sand most off this off to fill the small blemeshes Then final coat Finally the brushed stainless plate for the floor jack Next up is getting a new transmission, then finishing the exhaust 4 Quote Link to comment Share on other sites More sharing options...
