Vband makes it quicker and easier to remove the turbo as you dont have to screw around with the nuts that can be hard to get off after a while

other than that I dont think there is any real benefit - looks cooler!

V-band is much better. easier to position, better sealing, does not leak when hot, ummm easier to take on and off. you should use them everywhere that is possible! even for your exhaust joints if you have the $$.

that is the only downside to B-band I know of. Cost. they are much more expensive than traditional flanges.

i find my vbands on my tial gate screamer pipe and one on the hks t04z turbo to exhuast both leak from looking at them when removed, i have one further down the exhuast and that doesnt leak, any ideas to stop them leaking? they fit up perfect so its not like the fitment of the exhuast isnt right.

they shouldnt leak unless they are warped badly or have high and lows somewhere along the rings that is stopping it from sealing completely. But normally v bands are an excellent and bulletproof way of joining pipes.

I love them! All turbos should have them for exhaust in and out, would make it so much easier to fit and remove...plus neatness!

Ever sorted out this issue bro???

I've heard they seize up after a while as well

Any reoccurring probs with vband style flanges??? My concern is with the sealing.

i am assuming they are only leaking when cold and when warmed up are fine. I never hear a leaking noise or anything so it doesnt bother me. The car never got drivin often and was taken off the road shortly after so never really fixed it.

I've got the same thing...

I think The major advantage of V-Band connections off a turbo would be if ur dump goes straight into a bend... like mine...

I have nuts on mine and have to work the dump pipe off while i undo one of the nuts...

they are interchangeable just need the right diameter... not that expensive really i paid $10 each for the v band itself and the rings to weld to the pipework... my tial ext. gate, and 4 v bands on the exhaust...easier to take on and off and easier to work with in confined areas...

Speaking of v-bands...

Just been working on the exhaust system.

Unbolt the downpipe from the rest of the exhaust to get a piece of the exhaust out to weld the resonator into.

Hmm, the downpipe connection onto the turbo exhaust housing seems a bit loose or something.. *rattle* WTF the dump pipe just fell off the turbo! *takes the turbo 'beanie' off* WTF there's no v-band clamp on the v-band connection, IT HAD BEEN WELDED ON!! D: I have no idea how long it has been broken off like that for since the dump pipe connection to the rest of the exhaust would've been holding it in place, but it would've been leaking like mad and still is! Gonna organise a v-band clamp now, luckily the exhaust housing isn't broken! Only the weld.

In the pic, exhaust housing to the left, dump pipe hanging down on the right, you can see the broken weld on the turbo.

How far back is ur 1st exhaust mount??

Could have been caused by having to much weight hanging off the turbo...

      So, version 4 intake is on its way I was looking at these a while ago but at around $200 or more it was a little pricey for something that might not work, but, I had it in my watch list, but, I got a message saying it was on special, and I had a code thingie to use, it eventually came in at $120 delivered, so BAM, BUY NOW.....LOL I'll need to have a look when it arrives but I feel it will "look" better than what I currently have, as it comes with a PCV fitting, so I will be able to get rid of the alloy pipe that goes to the throttle body with the PCV fitting  Well, that's what the voices in my head are telling me  Oh, and this happened today Yeap, it was a Trojan, and it was cheap, so I headed back to the hardware store and actually spent a little bit more on a heavy duty,  one that was actually recommended by a plumber mate, a Cyclone one with a fibreglass handle that is actually rated for clay The broken shovel will eventually be "modified" into a short handle shovel

      What should I do next to hold the head on

      By MBS206 · Posted

      When you pulled it off, there is no signs of blown head gasket? Is it possible you have some other issues going on? Possible cracked blocked? Or do you think it's straight up lifting the head? Did you check what the head was torqued to before pulling it down (To see if possibly they're stretching, or starting to break threads out etc)?

      Chris' Toyota Mark ii JZX110

      By Rezz · Posted

      Seems like a decent result for a modded JZX110. They are bulky in comparison to the 100 and 90 models (which I'd prefer myself) but they are getting very few and far between here in JP these days. Thanks for the detailed review and the import process into the UK. I also have a car which I'm hoping to export from Japan at some stage so it's good to know if someone from the UK was interested in it. By the way the corrosion underneath is par for the course for cars which were located in/near the mountains or along the Japan sea coastline. They get huge amounts of snow every winter and the sodium chloride is used on the roads. Many cars have some kind of rubber like treatment underneath but they tend to limit it to the wheel arches underbody and fuel tank. Suspension arms and sub-frames will have similar corrosion to your JZX110 which is a common sight. See it all the time and car dealers here generally don't even mention it unless asked.

      If the sound goes away when you clutch in, the 1.5/2 way diffs are just shit, and you are a normal person. The diff is likely "fine" but driving at anything under 30kmh is a violent horrible experience. It would be exaggerated with solid diff bushings and subframe bushings if you have those.
