I have done a bit of research on welding, and was all set to buy a DC Inverter TIG welder for doing my own small exhaust cooler and intake mods. However before I got one off ebay, a friend of mine told me he has one (not DC inverter though) so I am going to borrow that instead and see if it does an ok job. My friend knows how to weld and will show me the basics, however he's used to welding thicker bits of steel than on an exhaust and he said the main worry is burning a hole through the metal because it's thinner.

My main goal is to cut a new front pipe to size and weld it onto the cat, and possibly weld some bolt-on flanges onto the cat to make it easier to disassemble (it's all welded together in one piece at the moment). I don't need to touch my aluminium cooler piping yet, but it'd be good to know when and how I can modify it later. I will probably go mild rather than stainless steel for my front pipe, to make any mistakes cheaper. So far I've found I need thinner welding rods as we only have 3.2mm ones. Any recommendations for rod size, and any other hints?

practice makes perfect. Sorry, but with welding (ive been doing it for like 10+ years) the only way to get good is to do it over and over.

Try it out on a few scrap pieces first, so factor it in when buying material.

Its hard to give tips without seeing someone weld firsthand, saying that, you can pick defects if i see em in the welds.

Thanks for the advice. Yeah I was going to get a few scraps of metal first and practice welding those, then when buying the exhaust tubing buy more than I need and practice on joining bits of those together.

      Cheers. Skyline is back on the menu, can’t get rid of it. It’s like a child you don’t want, or herpes

      I got back to Japan in January and was keen to get back on track as quickly as possible. Europe is god-awful for track accessibility (by comparison), so I picked up a first-gen GT86 in December just to have something I could jump into right away. The Skyline came over in a container this time and landed in early January. It was a bit battered after Europe, though—I refused to do anything beyond essential upkeep while it was over there. The clutch master cylinder gave out, and so did the power steering. I didn’t even bother changing the oil; it was the same stuff that went in just before I left Japan the first time. Naughty. Power steering parts would’ve cost double with shipping and taxes, so knowing I’d be heading back to Japan, I just postponed it and powered through the arm workout. It took a solid three months to get the car back on the road. Registration was a nightmare this time around. There were a bunch of BS fees to navigate, and sourcing parts was a headache. I needed stock seats for shaken, mistakenly blew 34k JPY on some ENR34 seats—which, of course, didn’t fit—then ended up having the car’s technical sheet amended to register it as a two-seater with the Brides. Then there’s the GT86. Amazing car. Does everything I want it to do. Parts are cheap, easy to find, and I don’t care what anyone says—it’s super rewarding to drive. I’ve done a few basic mods: diff ratio, coilovers, discs, pads, seat, etc. It already had a new exhaust manifold and the 180kph limiter removed, so I assume it’s running some kind of map. I’ve just been thrashing it at the track non-stop—mostly Fuji Speedway now, since I need something with higher speed after all that autobahn time. The wheels on the R34 always pissed me off—too big, and it was a nightmare getting tires to fit properly under the arches. So I threw in the towel and bought something that fits better. Looks way cleaner too (at least to me)—less hotboy, less attention-seeking. Still an R34, though. Now for future plans. There are a few things still outstanding with the car. First up, the rear subframe needs an overhaul—that’s priority one. Next, I need to figure out an engine rebuild plan. No timeline yet, but I want to keep it economical—not cutting corners, just not throwing tens of thousands at a mechanic I can barely communicate with. And finally, paint. Plus a bit of tidying up here and there.

      Nope, needed to clearance under the bar a little with a heat gun, a 1/2" extension as the "clearancer", and big hammer, I was aware of this from the onset, they fit a 2.0 with this intake no problems, but, the 2.5 is around 15mm taller than a 2.0, so "clearancing" was required  It "just" touched when test fitting, now, I have about 10mm of clearance  You cannot see where it was done, and so far, there's no contact when giving it the beans Happy days

      It's been a while since I've updated this thread. The last year (and some) has been very hectic. In the second-half of 2024 I took the R34 on a trip through Germany, Italy, France and Switzerland - it was f*cking great. I got a little annoyed with the attention the car was getting around Europe and really didn't drive it that much. I could barely work on the car since I was living in an inner-city apartment (with underground parking). During the trip, the car lost power steering in France - split hose - and I ended up driving around 4,000kms with no power steering.  There were a few Nurburgring trips here and there, but in total the R34 amassed just shy of 7,000kms on European roads. Long story short, I broke up with the reason I was transferred to Europe for and requested to be moved back to Japan. The E90, loved it. It was a sunk cost of around EUR 10,000 and I sold it to a friend for EUR 1,500 just to get rid of it quickly. Trust me, moving countries f*cking sucks and I could not be bothered to be as methodical as I was the first time around.
