Josh K. Posted February 5, 2014 Author Report Share Posted February 5, 2014 Lookin' good. Is there enough room around that pipe for it to expand when it gets hot? I had that problem on my Mustang... sort of. When I first got it back from the exhaust shop, It rattled until it got hot, at which point it just rubbed against the frame rail. There's about 1/4" between the CV flange and tube. About 3/8" between floor and tube. I should have it locked down pretty good with the hangers I bought. My biggest concern is the v bands sealing after I weld them... Quote Link to comment
Josh K. Posted February 5, 2014 Author Report Share Posted February 5, 2014 Josh, I'm not sure if you have seen this or not. Here is a oic under the original BRE #46, showing how they removed the mustache bar and plate mounted the diff. Maybe something like this could work for you? Thanks for the pic. I didn't know they solid mounted them. I fired off an email to Troy Ermish to see if he solid mounts and if so how much vibration is there. From my reading the z car guys say to avoid it at all costs. I'll take a look tomorrow and start formulating a couple different plans. Josh- Quote Link to comment

It didn't look like you had that much clearance. Carry on! Quote Link to comment
Josh K. Posted February 5, 2014 Author Report Share Posted February 5, 2014 Thanks guys! Had to round up materials today so didn't get a lot done. Tomorrow I'll hit it early in the am. Fit the rear section some more and finally got a hanger in place!!! Weld looks like crap but oh well.... Hanger: Clearance: Quote Link to comment
sssr20det510 Posted February 5, 2014 Report Share Posted February 5, 2014 can you do the cv adapters with the subie r180 sti diff?? how much ??? Quote Link to comment
Josh K. Posted February 6, 2014 Author Report Share Posted February 6, 2014 I could but honestly since it seems you can take apart the stock sti cv's (I couldn't on mine) then I would consider going this route: http://forums.hybridz.org/topic/73182-subaru-sti-r180-differential-and-axle-conversion-revised/ If you have a complete set of sti axles I could surely get you a price.

Josh K. Posted February 6, 2014 Author Report Share Posted February 6, 2014 I'm about 90% set on solid mounting the diff like the bre cars. If I do then I'll make aluminum bushings for the crossmember also. Quote Link to comment
KlassicMotion Posted February 6, 2014 Report Share Posted February 6, 2014 I guess the only reason they used the rubber bushings was to isolate any vibrations from the rear diff..... Solid mounting it should give better handling and responsiveness. How about, you try it out, and report back if you notice extra vibrations, and then start selling sets for the swap!! :thumbup: :angel: Quote Link to comment
Josh K. Posted February 6, 2014 Author Report Share Posted February 6, 2014 Yes for sure. If it's too noisy I can always build a different mount later... Quote Link to comment
KlassicMotion Posted February 6, 2014 Report Share Posted February 6, 2014 I mean really, if you put together an Internet store for all the parts you've made for your car, you might be able to quite your day job!! Well, at least you'd have some extra cash in your pocket, with the sacrifice of your free time.... Quote Link to comment
Josh K. Posted February 6, 2014 Author Report Share Posted February 6, 2014 That was my plan but I've never gotten it together.... Looks like the hood latch will clear the intercooler. The safety latch has to go though. That's OK because it sucks anyways. I'll build a much more reliable one later... I got the rear exhaust tacked together and the muffler mounted. Here's what I have left in radiused tubing.... Just gotta connect the front section to the cross member tube... There's one little section of pipe I'm not too happy about but I'm gonna let it slide. Also muffler is slighty angled. I'll fix that before weld out. All done besides weld out. Where's the pipe????? 7 Quote Link to comment
KlassicMotion Posted February 7, 2014 Report Share Posted February 7, 2014 Nice! Your right, when I look at some cars, and I see that pipe showing underneath, I don't like it. Kudos! Quote Link to comment
skyblue Posted February 7, 2014 Report Share Posted February 7, 2014 Very nice elegant solution. Quote Link to comment

Josh K. Posted February 7, 2014 Author Report Share Posted February 7, 2014 Thanks guys. John. When you gonna get that beast going again? Quote Link to comment
SR20DETdatsun510 Posted February 7, 2014 Report Share Posted February 7, 2014 Maybe after April i will resume. Quote Link to comment
KlassicMotion Posted February 7, 2014 Report Share Posted February 7, 2014 The only problem I have with your build is; that it makes me want to ditch the L20B in mine! Quote Link to comment
Watson Posted February 7, 2014 Report Share Posted February 7, 2014 "Where's the pipe?????" Hahaha, beautiful exhaust work. Quote Link to comment
Driftease Posted February 7, 2014 Report Share Posted February 7, 2014 God danm that's nice work. I have Shop/parts/machine/talent envy. Quote Link to comment
Josh K. Posted February 7, 2014 Author Report Share Posted February 7, 2014 Most of my work is done with a grinder :) Exhaust is all mocked up. Just gotta install 2 more hangers. I think at max the exhaust is 1" below the rockers. About 1/4" below tranny mount and rear cross member.... Had to notch the body a little. I'll fix this later... 1 Quote Link to comment
Josh K. Posted February 8, 2014 Author Report Share Posted February 8, 2014 Didn't get a whole lot done today. Cleaned up the shop and bought a drill press. Also Jordan (kayakdude07) stopped by with his dad. Always nice chatting with other 510 guys. Not many people have seen my wip :) I did put the last two hangers on though :) I drilled and tapped a piece of bar and welded it to the floor pan so the screws stay out of the passenger compartment. Tomorrow I'll pull the whole exhaust out and weld it up. Quote Link to comment
Josh K. Posted February 11, 2014 Author Report Share Posted February 11, 2014 Decided to wait on welding the exhaust until the turbo manifold, tranny mount and rear diff mount is done. This way I can take my time with the weld out and know nothing will move... 1 Quote Link to comment
Josh K. Posted February 11, 2014 Author Report Share Posted February 11, 2014 I also made a big purchase today. they're more of a luxury but I couldn't pass them up. Pics when I get them in hand! ;) 1 Quote Link to comment
Josh K. Posted February 17, 2014 Author Report Share Posted February 17, 2014 Started on the diff mount. Used some 1/2" 6061. Made a spacer block but had to set the mount plate in place so I could get the spacer thickness. I'll machine it to size tomorrow. I plan on making steel backing plates that will be tapped for 10mm hardware. These plates will be welded to the rear cross brace. 3 Quote Link to comment
