Yup completely agree. @boon I had a chat with GSS performance and they have speedflow AN fittings and braided lines all in stock so can get it from them. So you're saying go braided over any hard lines? I was moving away from going hard lines as they sound complex and seem to be prone to expansion issues etc. which if not done right could be a recipe for disaster. GSS recommended if i'm running a drain line near any of the exhaust manifold / upipe etc, would need proper heat wrapping to shield it.

Its my first time doing a full engine and turbo build. Not too sure about the benefits of solid/braided etc etc water and oil lines apart from looking pretty and being expensive as. I want a reliable and tidy setup - what is necessary to make this happen? Sinco recommenced these fittings and lines: -Speedflow braided turbo feed -6 pushlok water lines -Oil drain-Solid line past manifold into -10 pushlok hose onto block I am no expert with this stuff at all. Is a solid drain line important to have? Should i be running braided lines for all water and oil lines? Thinking i could go to speedflow and get all the bits myself if that made it cheaper, but need to know what to get!

It really depends on what your car is tuned for. If you were tuned on fully 98 pump gas, it really shouldn't make much of a difference if its mobile or BP. Gull force 10 has 10% ethanol - ethanol has a cooling effect on the charge before combustion so a tuner (only when tuned on this fuel) can potentially push more timing and get a little more power out of this fuel. Its the same principle as e85. You're not going to notice a whole lot at lower power levels on E10, but the gains will be larger the higher up you go. Putting Gull force 10 in a BP98 tuned will make it run less ideally and vice versa - im guessing this is where the conflicting opinions come about. Key is (from my experience), getting you vehicle tuned for a certain type of fuel and sticking with it.

I'll be there! Dark grey GVB STI

I looked up the cost, as was thinking about doing it as well. Pretty crazy tbh, didn't expect it to be that much at all. http://www.hpcoatings.co.nz/PriceList.aspx For $700 to just coat headers, i ruled it out very quickly

Hahaha dude that would be hilarious and painful at the same time

That's ridiculous lol. Is it front wheel drive? Must be time to buy the wife a new car

@Dre haha yes. Live and learn don't we..

I ran Falken FK 452s on my Legnum VR4. Were 19 inch wheels and tyres were 225/19/35. That combo with bilstein shocks was sheer brilliance. Handled like it was on rails. Did wear out pretty quick though. May have only got like 10k on em. My version 8 STI came with re003s. They were a 215/17/45 if I remember correctly. Handling was amazing. Very very predictable and responsive. Had so much confidence driving with them on. Wheels were Westport forged 17s I think. Then switched to Rota 18x9s on Michellin Pilot Sport 3s 225/18/40. I personally found that combo a bit weird. Couldn't really feel the road as well, wasn't as predictable and didn't have a lot of confidence at the limit. The current 2011 STI has re003s in a 245/18/40 config (if I remember correctly). Feels great and predictable again. Lots of options and opinions with this one aye! Going off my experience I'd recommend re003s. Thats just me though

This! Would love to know as well.

If there were thought out, researched and detailed plans behind these decisions that made sense. Then awesome, we could read and back that based on evidence and proper planning / foresight. What seems to happen (and this could just be the media as well, since that's all we see day in and day out), is decisions made without a lot of thought. Like the oil exploration.. Yes, oil will eventually run out, that doesn't mean you go cold turkey and don't find every last drop on our shores just to appear 'clean and green'. Thats like saying i'm sitting above a pot of gold but not going to dig it up because i want maintain a certain image of sustainability. Not the greatest analogy but you get the point. Should have been a proposal about how they were going to reduce oil consumption by XXXX year, and how they would transition out the use of existing NZ oil supplies after exhausting our natural resources. That would have been smarter business. Back to the fuel topic - I guess its just the feeling of being ripped off by all the players in the game. I'm taking the numbers shown online with a grain of salt. Businesses always have smart ways of hiding there profit margins. Still think their profit margins are pretty higher and monopolized by BP etc. as well. We heard how much profit they stated they made and it was something ludicrous (100s of millions). Z quote off stuff business - 'Petrol giant Z Energy defends industry competition as it announces a $263m profit'. 2016 BP new quote 'The New Zealand division of British Petroleum, one of the world's largest oil and gas companies, lifted annual profit 15 per cent in 2016 to $147 million'. Government regulation should be standard for this commodity. What would be great to see is how the 'other taxes' are spent by the government. Not just - roading, ACC, etc etc. But dollars against all the categories claimed it goes to. Easy to throw items on there to validate the tax, but what would really tell the true story, is how much the government earned from the 'other tax' per year, and how much was actually spent on the categories they state it goes to.

@IZichard Literally read the stuff article 5 mins after posting my comment haha doh Did the checker thing and came up reasonably close! These are the actual costs (apparently) based on 200c. Fuel itself: 58c GST: 26c Other taxes: 66c Shipping: 4c Margin: 46c so tax makes up nearly 50% of the total value.. And margin is nearly the same price as the fuel itself.. Sigh

I just really need to rant for a second sorry lol. This is one thing that really pissed me off about labours decision. How can you just increase (tax) the cost of fuel without properly working out the flow on effects to the cost of living. Its always the hard working middle class that will get shafted with this kind of thing. Example: Usual family has at least 2 cars they run. Take a 50L tank on each, and take the 22 cent increase in petrol price. Most people fill up once a week. 52 weeks in a year so: 52 x 0.22 x 2 x 50 = $1144 per year per average 2 car family! That's not even considering the cost of living increases as a result. What pisses me off even more is that other industries will choose to use this as an excuse to increase prices further (just the way the world works), which makes it much worse and even more unregulated. I can't believe they haven't thought about or published this kind of stuff. The icing on the cake is that the latest report shows the government has so much surplus cash as well, inherited from a well setup previous government of course.. Oh and let's not start about the under $400 import tax as well... Let's just tax the living sh#% out of everything.. Rant over.. lol But in all honesty, it would be amazing if someone could work out and breakdown where and to whom each cent per L goes.

Nice work guys!!

Thats a fantastic idea @Andy_Mac Need to try at the next drag day. Hopefully it doesn't fly off

Thanks guys. Really interesting discussion. So i was gonna go 2.75'' cold side (same as TB and intercooler outlet). Hotside i'm not sure though, as turbo outlet is 2" and intercooler inlet is 2.75". Feel like 2" piping might be too small for my power level - maybe step to 2.25" or 2.5" straight from the turbo?

According to thermodynamics, air contracts or becomes more dense as it becomes cooler. The particles move closer together when cold, and further apart when hot. That's the confusing part, because then the cold pipes should also be small to keep velocity up. Although that is not the only factor as mentioned above, i think the 'more air available cold side' is a factor but don't understand exactly why. Smaller pipes should mean greater pressure and greater velocity (pressure = force / area)

Beautiful. Love it when someone proves a theory with facts

Hmmm i too have ID1000s but was hoping on them getting me to 350wkw. At 75% duty cycle, your getting 4kw per 1% duty (i have no confidence this math is correct lol), so could i assumed +60 kw at 90% duty cycle (15% x 4kw) ? @gotasuby

Been thinking about this recently while planning for my FMIC setup. Why are cold side pipes larger than hot side pipes? Let's use my build as an example: - Turbo compressor outlet: 2" - Intake manifold inlet: 2.75" - FMIC inlet / outlet: 2.75" Sizing of the above is obviously a big influencing factor, but why would cold side pipes be bigger? Isn't the science that hot air is less dense and takes up more space? Therefore after being chilled through the intercooler, the space required for that same volume of air should be less, because it's more dense? I.e larger cold side pipes could cause lag because air velocity is now slower due to the bigger pipe diameter. Smaller hot side pipes make sense. Lastly what would you do in my application? 2" pipe from turbo to core, or have a transition somewhere in between or at the turbo even. Seen 2.25" on many intercooler kits. Likewise with the cold side, 2.75" from core to inlet or step it down?

I love subis, suby life all the way. But Nissans - SRs RBs etc, seem to be able to get more power easily in general. I mean look at their engine bay, so much easier to bolt on bigger turbos like mentioned earlier. But yeah stock STI turbos have really good spool and low down torque which makes them fun to drive. Was pleasantly surprised by mine as above. In an ideal world id have both an r32 GTR and my STI.. Dreams are free

Looks impressive@gotasuby, nicely done! Very promising for my build too What was the duty cycle on the injectors? Oh and was there any head work done?

Would love to the answer to this as well, as i'm considering getting one. The guys over in the U.S seem to swear by the 4 port, in conjunction with a twin port IWG.

Video or it didn't happen

Oh and also worth noting. Check if you actually need aftermarket headers or not. If you have an STI chances are probably not, unless you're thinking over 350wkw. But measure up your current headers etc first before you make a call, and talk to your tuner too That $800 could go to something more beneficial (case dependent), like for my build - porting.
