Im just finishing off a heap of changes on my rb25, and was thinking the briaded lines feeding my new turbo could use some protecting maybe, Ive got the exhaust housing ceramic coated, and the dump and front pipe heat wrapped already

Am I being overly pedantic to want to use heat resistant or flame proof insulation on the braided lines?

Ive seen other turbo installs using braided lines with no ceramic coating and no hose protection and the owners seem ok with running like that, but would it be recommended to use some protecting sleeves on the lines?

As for General Cooling

Im running a vented bonnet, a HKS oil cooler, a ARC super induction box with air feed from bonnet, and of course a Greddy FMIC & radiator air guide along with a RIPS front facing plenum, all in the name of response and cooling...

I was thinking of making a front undertray/splitter with air guides to the front brakes & oil cooler located in front of passenger wheel.. would making it out of alloy sheet be ok or does anyone have other suggestions? it would possibly be out past the front bar by 3inches or so, it may be only track friendly.

Any other cooling suggestions?

If you want to get right into it, check out Pyrotek Pyrojacket.

Have seen it on some top-notch, HIGH-powered cars... Bright orange, flame-proof heat-shield for hoses.

That being said have also seen many high-powered cars running bare braided lines (as you mentioned)

Like everything, just depends how far you want to go I suppose...

I personally have been running unshielded Aeroquip (hi-temp "rubber") water lines & oil drain from my turbo for years & they are still like new.

No ceramic-coating or even heat-shields around my turbo either. Will be a job for next time turbo's off but not a problem so far...

General cooling is the same, depends how far you want to go... Could ceramic-coat (or insulate someway) what intercooler-piping is under the bonnet & piping from airbox to turbo, ceramic-coat manifold, heat-shield &/or wrap everything, bigger radiator, etc, etc...

thanx, sounds like I could be getting a tad pedantic then,

has anyone wrapped the exhaust manifold?

Looks like it would be a tuff part to wrap properly, 1in wide wrap or thinner???

What braid are you running?

Regular rubber stuff will need protection if it's running very close to manifolds as it's only 130 degree resistant. Just get a hi temp sheath for it http://www.mscn.com.au/Scripts/prodView.asp?idproduct=495

Teflon stuff is more resistant and you will have no issue with it in 99% of applications (as long as it isn't directly resting on anything) as it's rated over 230 degrees. costs more, but not much more than regular braid and a sheath.

      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.
