Also not been on in a while just getting settled at wk and getting house baby ready (cleaned from top to bottom) trev i had a look at the dishwashers the asko have not much in em but apparently i get paid well on em ;) and the other 1 was about 200 off or something like that

Can cast iron be tig welded to cast aluminium now?
 
I thought you needed friction welding or some other impractical method to weld those two together [emoji14]


I didn't say it would be strong

Cheers mate, I'll ask the current dishwasher what's she wants to do/get

Yeah hardox is wear plate it comes in different higher tensile strengths and is common for use in load bearing/abrasive applications. Loader buckets, mills etc. More R+D from the master! Did u stick weld it?


Yep that's a jib alright! Any pics of your handi work?

DSC_0377.JPGbeen working on this stuff the last few days. Catch can with stack dual 2 " inlets to 3" outlet. reducers 10" nom from manifolds with bellows up to dual 12" nom exhaust pipes, dual 10" aluminised air intakes and all the engine coolant tubes for a M.T.U. Or (mostly troubled unit.) power generation. The 2x12" exhaust pipes run to a dual side inlet silencer 4' diameter 18" outlet with stack mounted on a frame outside the engine room. Show us your diesel!
Its running around 420hp on 98 and 480hp on e85 but took out the e85 tune to make the 98 one cleaner ( no e85 in my area ) on gtss turbos with kelford 265 cams. Bit lacking in power, really need to be up in the 500hp for a gtr but cannot complain I spose :4_joy:. Has full haltech catalogue as well

is that from the left side of the boot? you put the jack behind it and expands into it holding it firm?

Hey Pal are you still going to coffee and cars. Dead keen to check out the beast? Boss from work is taking his caddie down aswell apparently?

Can't really see a reason to weld the dissimilar metals together? That would be highly specialised. One is a aluminium based alloy, The other iron based. I've repaired a few cast Ali/iron heads for cars/drag cars before. Fully F/G clamped the head to a 2" thick cast iron milled table. Pre heated with the oxy gently/the entire head gradually. Grooved out the crack with Ali Burr on the die grinder, down to where you can't see where the crack started, welding well before where the crack started and finished using cast Ali rods and pure argon. Post heated the head gradually to a cool down. The heat transfer properties and molecular structure of the materials are pretty much a polar opposite. Alloys are loose softer and dance freely, high thermal expansion and contraction. Irons are tighter don't dance and have low thermal expansion and contraction. Alloy's s are a/c welding with tig for castings. Iron's Are d/c - welding with tig for castings. They both have a tendency to spit the filler material out if you weld it too hot, that's where the pre and post heating comes into it. I crank the hot start up a bit because you will create a weak point if you hang around to get the weld puddle pooling. Easy on Ali harder for lower amps on cast. Nature of the beast. The pre-post heat is more critical on the alloy than iron. Just a thought? Our new Kempi tig has a mix setting that combines Ac/dc current and has a synergic setting as well? Can't beat the old analouge Hobart welder so far as I'm concerned. Digital, high low high low, analouge higgghh lowww, higgghh, lowww. Makes for beautiful pulse welding! Alternatively you could mash a heap of bird shit into the corner and hope the flux and slag sticks it togetherB-) bronzing, brazing, solder, pop rivets, silicone. Nuts and bolts etc:-)

Yeh mate. I'll be there

    • I might be way off the mark here.. there must be a T junction under the manifold. That takes manifold pressure through a check valve prior to the T, one side splits out to this bleed off orifice, the other straight to the wastegate actuators. 
    • Carrying out some engine due diligence before my first drive in a 260RS that has been in storage for 10+ years, and found two lines that are susposed to be plumbed into the boost control solenoid. One of the lines (the wastegate boost supply line) to actuate the gates, had a bolt in one end blocking it. The other line (main boost signal line) from the very rear of the intake manifold (RB26DETT) and runs up to the boost controller had this pill in the end of it as seen in photos. Other than the obvious (T28 Ceramic turbos might well be cooked)  Can anyone shed any light on if there is any validity at all with this mod, bleeding a constant fixed rate of manifold boost pressure off through this 3mm hole?  Is it deliberate?  Was this a 90s Jap mod done to RB26's? Or has someone just fitted this without any idea of what happens to ceramic T28s if they are not gate controlled?    
    • This looks great! Awesome to have the 5 speed with an LSD in this. The Recaro's look like SR2's or SR3's. It's a shame they've been retrimmed as they would have looked sweet in their original colours. I think I'd want my agent to be a little more up front and informative too. I've never imported but I reckon it would make me a little nervous, so the more info the better.
    • Thanks for doing that Duncan! Makes you a good person in my books. We don't get kangaroos or wombats here. But we have bats and it's similar. AFAIK it's often the mums with a baby attached that get hit because they drop lower when starting from a tree. If you hit an animal, check on it. https://www.ifaw.org/au/resources/wildlife-rescue-app An app to get the closest wildlife rescue contact.
