Im in the same boat mate, and i have looked around alot and can't seem to find 2" ones...... seems 2.5" is the more available one..... i want to v-band my external wastegate pipe, but was looking to have to increase it to 2.5" before it joins exhaust so i can get clamp to fit....

One 2" clamp id love to get would be if TIAL released there 2" in a kit.... they seem nice.

I guess you could order a spare set of tial ones , with just twice as many weld on flanges to make up a standalone v-band clamp.... im going to try that way for cost i think.

Was in the same boat for my gate tubes. I ended up ordering a set of Tial ones and Tial v-band clamp from GCG that suit the 44 mm gate. I then had to get the other side machined up by an engineering firm. That way I had a male and female v band.

Anyway here's how it looked before the final instal. My tuner - Glenn "Lumpy" Campbell with his masterpiece

....and the other side of the equation:

Wow, some nice work there mate ! Ahhhh yeah i forgot the Tial V-bands are Male-Female..... damn... shame they done make them as a set.

I did find some 2" ones out of the U.S Might just have to import a few i think.

I emailed a mob in the US this morning about getting 4x extra flanges and an extra clamp for 44mm TiAl gates so I can make my screamer/plumback hot swappable. Figured it would be easier using all the same size stuff that comes off the gate.. wasn't aware of the male/female thing though :P

Juggernaut, where did you get those flexes from? I need one for the plumback and a 3" one for the dump pipe.

Re the male/female bit - the Tial v-band flange has a recess in it - this lines up with the boss from the gate - so you have a positive positioning of the v-band flange to the gate and are not relying solely on the clamp to hold everything into position. So if you only buy the Tial flanges you will end up with two flanges with the recess. Thats why I then had 2 v-bands made up with the boss - you can see the raised inner 'male' boss in the pictures of the dump tubes. The other alternative I considered was to have a ring lathed up - the ring could sit in between the 'female' recesses of the Tial v-bands and lock the two flanges together and the whole assembly would be held together with the clamp.

I may have a couple of new Tial flanges (to suit the 44 mm gates left over) if anyone is interested - I would need to double check. You would need to get a couple of "male" flanges lathed up tho. Embleton Engineering in Perth did mine.

The flexes for the dump tubes I got from Genie Exhausts in Myaree in Perth. I didn't use one for the dump as I though the v-band off the turbo may allow for some sideways movement anyway - it hasn't cracked however I do use a brace across to the gearbox to support the lower part of the dump.

Very interesting, I think I could get away with 2x "female" flanges and 2x "male" flanges (one blanked). What was the rough price on lathing up the male flanges? would prefer to have the locator integral with the flange instead of having little bits that can be lost when swapping :P

Still need to order me another clamp for the front pipe end of the plumback. I can only find flanges for sale in Australia, no clamps :P

I bought the Tial V-bands flanges and Tial clamps from GCG. Ordered them one day - delivered to Perth the next.

From memory cost of lathing up two stainless flanges was approx $50 - $60.

Excellent, cheers for your help :P

P.S. if anyone is interested, I just found a website called bestmuffler.com, company appears to be in NSW and seem to have a lot of reasonably priced stuff such as flexes, bends and larger v-band clamps.

That clamp in the pic looks identical to the Fleetguard one I bought through Cummins for my front pipe at a cost of $22. If you've got a dealer nearby they could be worth looking into, I'm always surprised at how many bits and pieces I can get through there! I've not looked into buying flanges due to not needing any, but they are the expensive bit right? (I'm thinking that you could always get an engineer to knock some up for you easily enough though)

      Duncan's V37.......race car?

      By Duncan · Posted

      To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules

      Duncan's V37.......race car?

      By Duncan · Posted

      So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket

      As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year.

      I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
