auxilary Posted September 30, 2004 Share Posted September 30, 2004 I am considering scrapping the rotary project because I'm having a difficult time with [cost effective] welding and design of the turbo manifold at the moment, and because of that the project is taking 3x longer than it should have. Would anyone be interested in picking up where I left off? parts: -13b-re 2 rotor cosmo motor. Looks like it was rebuilt before I bought it. Oilpan gasket, oilpump chain, and front cover gaskets have been replaced. motor has compression, and has been lubed with ATF and turned on a regular basis. Has custom mounts for datsun 240-280z. comes with series 5 rx7 flywheel that needs resurfacing -2 rx7 turbo transmissions -brand new garrett t04s turbo, oil cooled only. 60-1 wheel, .7 a/r cold, .84/ar divided hot, p trim exhaust. -custom engine side exhaust flange for manifold. -stock twin turbos, if anyone wants to use them -brand new in box ACT street/strip heavy duty clutch -rx7 oil cooler -small npr intercooler, 20x8.5x2 core, 2.5" outlets -microtech LT8S ecu, brand new in box, manual, harness, fuse plug, etc. -magnacore 10mm wires -HKS sequential blow off valve -brand new tial 44mm wastegate with 11.86psi spring and v-band clamps -misc. stainless steel piping, 45 and 90* bends in schedule 10 304ss, 1.9" o.d, 1.682 i.d. to make exhaust manifold , 3" bends to make downpipe -2 primary 550cc high impedence injectors, cleaned and tested by RC engineering -2 secondary 1680 (yes, 1680)cc low impedance injectors from Marrin injectors (microtech can drive low/high imp. injectors separately) -modified fuel rails to accept -6an lines -walbro 255lph external inline fuel pump. 255lph @ 43psi. 6an and 8an fittings available -aeromotive a1000-6 fuel pressure regulator with 1:1 boost ratio. -autometer fuel pressure gauge -new in box autometer phantom boost gauge, to 20psi -new mazda waterpump -new mazda clutch slave -new mazda intake manifold gaskets The motor's light, without the turbo and accessories probably weighs around 180lbs. My friend and I move it around the garage with the transmission attached by picking it up and just carrying it over to another spot, to give you an idea. Transmission is probably around 100lbs. This is why the motor sits so far forward, compared to how much further back I can move it, because I wanted some weight over the front wheels. probably more stuff that I can't think of at the moment. Some parts still need to be purchased, like couplings, piping, oil cooler lines, etc.... but... any interest? Quote Link to comment Share on other sites More sharing options...
Tim240z Posted September 30, 2004 Share Posted September 30, 2004 Any idea what you would want for the whole enchilada? I have a couple of Opel GTs that are crying for a conversion.....but this may be a bit over my budget Quote Link to comment Share on other sites More sharing options...

Tim240z Posted September 30, 2004 Share Posted September 30, 2004 Checked....wheels in my head are turning....esp. your last comment..... They are small wheels, so hold tight.... Quote Link to comment Share on other sites More sharing options...
johnc Posted September 30, 2004 Share Posted September 30, 2004 I'm having a difficult time with [cost effective] welding and design of the turbo manifold at the moment, Expand on this problem. Maybe I can help. Quote Link to comment Share on other sites More sharing options...
auxilary Posted September 30, 2004 Author Share Posted September 30, 2004 The guy who was going to be doing the welding is telling me that he's booked up through all of october and possibly november (he's doing it at 45/hr), and the only weekend available is this weekend. Unfortunately, my divided flange hasn't arrived yet, and a server at work took a crap. I was working on it until 11pm last night, and I have to do more work tonight, which means I can't get the car towed to his shop to get stuff done (more scheduling bs that'll require 3 more paragraphs) The problem being welding up the manifod and designing it on the fly. I have a general idea, and a ducttaped mockup (sort of) to go with it. I'm getting $1,000 and up quotes for the manifold design, even though it's pretty simple, it just needs to be robust enough to hold the turbo and take abuse. That's even with materials provided. Shoot me a PM Thanks, -alex Quote Link to comment Share on other sites More sharing options...
auxilary Posted September 30, 2004 Author Share Posted September 30, 2004 btw, if anyone knows competative not-so-expensive welders in bay area, let me know Quote Link to comment Share on other sites More sharing options...
Vintage-TechZ Posted September 30, 2004 Share Posted September 30, 2004 Aux, Any chance the stainless manifolds that SS Autochrome sells on Ebay would fit ?? Very inexpensive ,nice parts(my boss has purchased 3). Worst case scenario you could use all of the flanges for sure and cut and retack the rest to fit your application ? ..............Vince Quote Link to comment Share on other sites More sharing options...
auxilary Posted September 30, 2004 Author Share Posted September 30, 2004 no. no regular manifold would fit, otherwise I would have gotten this done and over with. all FC/FD turbo manifolds sold commercially move the turbo forward and to the left. Mine needs to tuck in and move towards the back of the engine. Or a foot forward. I already have the flanges, so that's not an issue.

Vintage-TechZ Posted September 30, 2004 Share Posted September 30, 2004 OK, I gotcha' now..........you just don't have a chop saw and small 110 welder to tack weld your mock up,so you can have someone (available) to do the final heat !?? Sounds like J.C> may be willing to help out! Save Heart,,there are many obsticles to being original !.........Vince Quote Link to comment Share on other sites More sharing options...
auxilary Posted September 30, 2004 Author Share Posted September 30, 2004 I appreciate John's help, I might be sending him the exact measurements in cad with parts to weld up...but he's still 400 miles away and it's a hit/miss with welding the manifold together for a proper fit. John C., can stainless be tacked together with regular wirefeed mig? Is it going to leave some ugly residue?Maybe I'll con Jumbo240ez to help out with lures of free beer....

johnc Posted September 30, 2004 Share Posted September 30, 2004 John C., can stainless be tacked together with regular wirefeed mig? Is it going to leave some ugly residue? Yes and maybe. But why not just buy a small (2 lb) spool of stainless wire in the same diameter as what you're using now? You can also weld the whole dang thing together yourself using stainless wire in your MIG welder. You'll probably have to turn the power down a bit from what you'ld normally use for steel. Get some extra stainless tubing and practice before welding on the real part. I don't know what size stainless tubing you're looking for. I have a few scrap lengths of 1.250" OD .063" wall 304 stainless tube lying around that I can sell for $1 a foot plus shipping. Quote Link to comment Share on other sites More sharing options...
auxilary Posted October 1, 2004 Author Share Posted October 1, 2004 Do I need gas to weld stainless, or can I do wirefeed without gas? What, no one is interested in the swap? Quote Link to comment Share on other sites More sharing options...
johnc Posted October 1, 2004 Share Posted October 1, 2004 Gas is always best but you might be able to find flux core stainless wire. Quote Link to comment Share on other sites More sharing options...
Heavy Z Posted October 1, 2004 Share Posted October 1, 2004 What, no one is interested in the swap? You could try Joe Viturbo, I hear he's looking for a new ride. Quote Link to comment Share on other sites More sharing options...
Guest butlersZ Posted October 2, 2004 Share Posted October 2, 2004 here's a source for stainless flux cored wire. They sell many types of wire. http://b2b.airgas.com/browse/product_list.aspx?catID=8 Welding stainless with flux core wire isn't too difficult, just use some welders anti-spatter spray to make the welds cleaner, that way you won't be chipping off all that slag and have the spatter beads.
