Thanks Disco! Yeah all of that is definitely what I would like to happen, as I completely agree that a separate dump/front is a lot better - only problem is finding one. the only separate dump I could find on JJR (which is as far as I've been able to search so far) is a HPI one for $500 ish...

I won't make any decisions until I've spoke to my tuner and had his advice on what to buy and where from given to me, as the main reason I want something ASAP is so I don't screw him around any more.

I went for the 1 peice SS split dump from AM Performance here in Adelaide. Beautiful, high quality construction and it does not foul waste gate flap and cause boost spiking. I bought his hi flow 3" cat too at around $600 for both from memory.

Do a search on the forums, I don't think Andrew has one unhappy customer. Andrew: 0401865373

A used HKS one would be an excellent option, I saw a few on yahoo japan and local egay lately.

While I do agree with disco to the 2 piece affair, I did just removed my stock turbo and 1 piece dump from my own car. I actually was able to remove the dump quite easily with minimal stress. I simply unbolted it from the cat then unbolted it from the turbo and slid it out. There was no magic to it, it was just a well constructed item that had plenty of access clearance for the dump flange bolts.

And now for a shameless plug: the item is now for sale :touch: I am looking to swap it for a half piece like what came off your car Trozzle. PM me if you want to do a straight swap or even cash your way (depending on quality of your item).

Cheers,

My dump is stock, so I don't think you want it :touch: 2.5" mild steel, seen 17 years of (ab)use

How much would you want for yours? I'd need to get it posted down to Canberra though, so not sure if you're keen to stuff around with that. Also what size is yours and what power you making with it?

I just spoke to the tuner though, he said they'd be fine to source an appropriate part for me if needed. More or less my only concern here is that I don't stuff them around and waste their time. As long as they're happy with what's going on, then I'm happy.

Mine is an 80mm one piece front and dump.

And id be wanting your front pipe, not ur dump pipe lol. The bit that goes from the stock dump to the cat. PM me what size the inlet and outlet is, and I can more than likely post the item to you if we agree to do the deal.

Im wanting a pipe that is 70-80mm at both flanges, no less than 70mm. As stated, PM me.

ah ok. Well if you can hold out a little bit (by all means keep looking for something anyway, don't wait for me) until wednesday when the car will be looked at etc at the workshop, I can tell you if that will work. I will admit, I'm fairly ignorant as to what is ACTUALLY on there, and whether or not the cat is flanged or slip/weld on to the front pipe. Especially considering I thought it had an AM dump, and it's now stock, I'm not making any more assumptions lol.

Otherwise, if it will work with the workshop, and what I currently have in the way of a front pipe is what you're after (3.5", and flanged at the cat - 3.5" flange) I'm keen to do a swap with you.

lol no problem. 3" is actually 75mm and I only need that the flanges are no less than 70mm. My pipe is off the car and I wont be needing it back on any time soon, I dont drive it. No rush.

Ill go down to the post office and ask them about postage, PM me your details for an accurate quote.

This.

Andrew's level of workmanship is mindblowing... he will custom make anything that you request and it will last the life of the car unlike anything in mild steel. AM performance backs all his products and if they ever fail due to workmanship defects he will repair no worries.

Heres a pic of a GTiR kit he makes and sells worldwide. fits in all factory location and clears everything.

Tried calling him but no answer.

Any idea how much I'd probably be looking at for a 3.5" bellmouth dump from him? I'll wait until workshop gives me exact measurements for the flange etc before I go buying anything though.

For the power levels you're seeking I dont think you need a 3.5' bellmouth... Simply get a JJR 3" stainless dump/fornt pipe and bolt the f**ker in place! Worked a treat on my r33 gtst and I was at 235rwkw on 14psi with a lesser turbo than yours without any restriction.

if he doesnt answer the phone he's most likely working.. he's a one man operation atm. leave a sms with him or email on [email protected]

Any exhaust place should be able to make you a 3 inch bellmouth using the flange of your standard dump pipe. That's what they did with mine and it came up a treat, there's nothing that special to dump pipes, in the end it's just a hollow piece of metal (above workmanship does look nice though)! 3" is plenty for what you are after, why give up the backpressure for unnecessary size?

backpressure is never a good thing, the bigger the better when it comes to turbo exhausts, always! Obviously to a point though, a 5" dump isn't going to be of benefit.

Yeah it all makes sense, I just don't want to shoot myself in the foot all because I'm rushing it a little. Thanks for all the advice though, at this stage the JJR one does look to be the most appropriate, as it's cheap, large enough for what I'm after, and bolts right up. Still leaving final advice to tuner of course tho :blush:

As always, thanks again guys :wub:

    • Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!
    • 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
    • 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.
