hey, can anyone tell me if there would be much difference between a cheaper ebay item like THIS for $280 including post, or getting a brand one for about $800??? as far as i see it, it's just stainless pipe and there wouldnt be too much difference at all, but just after some opinions.

Cheers, Brad.

i used ebay dumps on my gtr and i had to skim the flanges and die grind a lot in side them if it was a manifold defernetly dont buy as they crack all the time but dumps and front pipe wouldnt be to bad if your budget wasnt big enough for name brand stuff

you can use cheap/copy parts in some places without a problem.

However a dump/front pipe is a pain in the ass to change, hence i would spend the money on something that you won't have to take off.

OR

but the cheaper copy, and get it cleaned up/welded and so on before putting it on. Will cost couple hundred at least

ebay is a bit of a hit and miss... some may fit perfect, others wont. it comes down to manufacturing quality therefore china vs. japan (or a better factory in china again in some cases)

i got a jjr one, for the price they are pretty good, fit up well and i haven't had any problems with it.

This is the pipe setup that I purchased. I'd avoid it if you don't want to do some home panelbeating with the thing. The system sounds nice but when installed you need to pad the front pipe or it will vibrate against the car body. Dump pipe is giving me alot of wastegate issues at the moment...I'm diegrinding the hell out of it to make more clearance for the wastegate flap. It is one of the "safer" cheap eBay items, but if you don't want the f*** around that I'm going through at the moment then just think of this as a $280 mistake you'll have to pay on top of a branded system that does fit perfectly.

I don't think they've even bolted these items up to the cars they're designed for. Appear to have just gone off the most basic measurements and estimations.

Would installing the dump pipe for a bigger turbo help on the response? Or the difference is not that big afterall? I'm contemplating to put the HKS dumps on since thats gonna cost another 4hrs worth of labour (gonna put on HKS front pipe). It'll probably be worth it if you're changing turbos but from how I see things, its not worth doing it atm.

    • 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.
