HI All!! just though i would share with everyone my Car and what she made and mods! post what you have , i would like to see what others are running!

im from WA Bunbury

Got it dyno tuned yesterday (Monday)

Mods are

Garret High Flow GT3076R from Adelaide Turbo Service with Factory Rear and front housing

Nismo 740CC Inj

Exeedy Heavy Duty Clutch

Walbro Fuel Pump

Custom Stainless Intake with Cold air induction

Autobahn88 front mount intercooler

K&N Pod Filter

Spitfire coil packs

Iridium spark plugs gapped to .08

Full turbo back split dump HKS 3 inch Exhaust with hot dog and streight through rear (Milo Tin) :P

HDI Electronic Boost Controller with high and low settting

Haltech Platium Pro ECU

It was a very hot day yesterday! outside temp was around 32 Degrees, the dyno room was 38.5 so it was hot!!! so that would effect the tune a litte bit..

on 19psi i made 359.2 RWHP , took it for a drive and it was nice but didnt like it very much to much wheel spin, so wound it back to 17 PSI which was the sweet spot between good traction and no traction for Final Run and it pulled 337.3RWHP on 17PSI i was happy with that, i can wind it up have a little play if i want :P as it was tuned to 19PSI

on 10PSI LOW Setting i made 278RWHP

Thanks!!

The dyno adjusts the power reading to suit the ambient temp. Unless their ambient temp sensor is out of wack/not there. Theres a crewman ute here that a dodgy workshop claimed was the most powerful in the country, but its easy to claim that when the ambient temp is 50-60 degrees c. Funny things happen when you put the probe near the exhaust.

Also next time you do plugs, bin the iridiums and go copper. They really work just as good and are a quarter of the price or less

Thanks for the info 89CAL, i have never actualy tried the copper plugs... there are so many talks about the 2 and whats best to run...

The tuner who tuned my car deserves a pat on the back , alot of people are all about numbers and never appreciate the actual tune the tuner has done.

90% of the tune is bedding them in, the last 10% is the horsepower runns making people happy when they see bigger numbers, sure i could of got bigger HP but that means running a more aggressive tune. which i didnt want. my car starts perfect everymorning, i work early starting at 4:30 and its super cold.. but She starts and goes like a standerd car!. but when i want the power is there running perfect mixtures so i know that it wont go bang!

my setup is perfect for street/track. the highflow starts to taper off higher in the higher speed, but would like to take it down a quater mile and see what it does!

Copper plugs cost around $3 each, the iridium and platinum ones are what, $30-40 each? What harm is there in trying copper? The expensive plugs last longer, but for the price offset I don't think they're worth it. Copper ones arc better anyway, and are cheap enough to replace every 30,000km or whenever.

I would be lucky to travel 3000km per year, but I wouldnt wait 10 years to change. For $18/set, every 12 months works for me. :action-smiley-069:

Last set of Iridiums I got from the US were $10 a plug each, delivered, and VQ engine LFR's are much less common.

When you are melting copper plugs from running massive cylinder pressure and high heat you may appreciate the Iridiums a little more. Coppers are for stock cars running rich shitty tunes imo, as they are cheaper to change when they foul. That's why tuners recommend them I think. I guess every engine design would be different too, my VQ has much better plug cooling than the RB, as the thread is twice as long.

I think if your melting coppers then you've got some other issues... Copper melts at 1085 c and aluminum melts at like 660ish maybe try using a different heat range copper. I know guys that have pushed past 400rwkw using coppers with no problems

You have used aluminium plugs?

You know the price of 8-10 heatrange racing plugs? Around $40 a plug last I checked, and they needed to be specially ordered in.

My NGK LFR7 Iridiums are handling everything i can throw at them, the last set of Denso iridium IKH22 7's melted in just 5000k's.

No but my head and pistons are aluminum and whilst they have a larger surface area and also have the luxury of a boundary layer I would say that if your making enough heat to melt coppers your making enough heat to damage your head and pistons. Det much?

Ahhh ok.... My engine has been pushing 30-40 psi on ethanol for 4+ years now, daily, Should I check the pistons again? They looked fine when I changed the head gasket last.

My block is alloy too, with a sleeve bore, should I be worried much?

So if your pushing 30-40 psi on ethanol in a vq what does that have to do with a rb using coppers on ulp on the street? I work on engines that only have 2 plugs no pistons and run 1800shp at 60,000 rpm using jet a1 but that has nothing todo with an rb using ulp on the street so what's the point in mentioning it? Coppers run fine in rb's at over 400 rwkw on ulp.

The point I already made was... Iridiums are simply better. They handle high heat conditions much longer than copper, and you don't need to change them out every 5000. For just double the price they would pay themselves off many times over.

Now you need to mention that bullshit about coppers making more power....

I never said coppers make more power. Spark is spark, as long as its sufficient to create full combustion it really doesn't matter. 1 electrode plugs to 1 million electrode plugs bugger all difference. Electricity will always take the path of least resistance. Coppers are cheap, they work fine at higher levels of power than 90% of people will see and if changing cheap plugs every 5000 kms is to hard then pay an exorbitant amount for fully sick plugs for your street car (we are talking about street cars here)

Yep, street cars. Mine is no 2 ton race car. lol.

I think all modern street cars run Iridium or Platinum these days for the cleaner burn and longer servicing times.

How many people would seriously want to change plugs more often than oil? Most of the servicing I carry out, the cars have done 10-15,000 between oil changes.

I change my oil every 5000 like most people I know. It's just part of regular maintenance. The op doesn't have a 2 ton race car so suggesting coppers isn't a problem and what modern cars come with iridiums standard?

I do oil change every 5000km, do plugs about every 20,000km. But I have left them longer at times and never had an issue with the coppers.

I'm sure the Iridiums are fine, and last longer. But I don't believe they last as long as they are advertised

My view is that coppers work just as well and are alot cheaper, so thats what I do. Not saying that they are the best thing out there, but they definently work for the power levels most of us are running. At the same time though, I can get to my plugs alot easier without the standard manifold and piping :)

    • Update 3: Hi all It's been a while. Quite a lot of things happened in the meantime, among other things the car is (almost) back together and ready to be started again. Things that I fixed or changed: Full turbo removal, fitting back the OEM turbo oil hardlines. Had to do quite a bit of research and parts shopping to get every last piece that I need and make it work with the GT2860 turbos, but it does work and is not hard to do. Proves that the previous owner(s) just did not want to. While I was there I set the preload for the wastegates to 0,9bar to hopefully make it easier for the tuner to hit the 370hp I need for the legal inspections that will follow later on. Boost can always go up if necessary. Fitted a AN10 line from the catch can to the intake hose to make the catchcan and hopefully the cam covers a slight vacuum to have less restrictive oil returns from the head and not have mud build up as harshly in the lines and catch can. Removed the entire front interior just shy of the dashboard itself to clean up some of the absolutely horrendous wiring, (hopefully) fix the bumpy tacho and put in LED bulbs while I was there. Also put in bulbs where there was none before, like the airbag one. I also used that chance to remove the LED rpm gauge on the steering column, which was also wired in absolute horror show fashion. Moved the 4in1 Prosport gauge from sitting in front of the OEM oil pressure gauge to the center console vents, I used a 3D printed vent piece to hold that gauge there. The HKB steering wheel boss was likely on incorrectly as I sometimes noticed the indicator reset being uneven for left vs. right. In the meantime also installed an airbag delete resistor, as one should. Installed Cube Speed premium short shifter. Feels pretty nice, hope it'll work great too when I actually get to drive. Also put on a fancy Dragon Ball shift knob, cause why not. My buddy was kind enough to weld the rust hole in the back, it was basically rusted through in the lowermost corner of the passenger side trunk area where the wheel arch, trunk panel and rear quarter all meet. Obviously there is still a lot of crustiness in various areas but as long as it's not rusted out I'll just treat and isolate the corrosion and pretend it's not there. Also had to put down a new ground wire for the rear subframe as the original one was BARELY there. Probably a bit controversial depending on who you ask about this... but I ended up just covering the crack in the side of the engine block, the one above the oil feed, with JB Weld. I used a generous amount and roughed up the whole area with a Dremel before, so I hope this will hold the coolant where it should be for the foreseeable future. Did a cam cover gasket job as the half moons were a bit leaky, and there too one could see the people who worked on this car before me were absolute tools. The same half moons were probably used like 3 times without even cleaning the old RTV off. Dremeled out the inside of the flange where the turbine housing mates onto the exhaust manifolds so the diameter matches, as the OEM exhaust manifolds are even narrower than the turbine housings as we all know. Even if this doesn't do much, I had them out anyways, so can't harm. Ideally one would port-match both the turbo and the manifold to the gasket size but I really didn't feel up to disassembling the turbine housings. Wrapped turbo outlet dumps in heat wrap band. Will do the frontpipe again as well as now the oil leak which promted me to tear apart half the engine in the first place is hopefully fixed. Fitted an ATI super damper to get rid of the worn old harmonic balancer. Surely one of the easiest and most worth to do mods. But torquing that ARP bolt to spec was a bitch without being able to lock the flywheel. Did some minor adjustments in the ECU tables to change some things I didn't like, like the launch control that was ALWAYS active. Treated rusty spots and surface corrosion on places I could get to and on many spots under the car, not pretty or ideal but good enough for now. Removed the N1 rear spats and the carbon surrounding for the tailpipe to put them back on with new adhesive as the old one was lifting in many spots, not pretty. Took out the passenger rear lamp housing... what do you know. Amateur work screwed me again here as they were glued in hard and removing it took a lot of force, so I broke one of the housing bolts off. And when removing the adhesive from the chassis the paint came right off too. Thankfully all the damaged area won't be visible later, but whoever did the very limited bodywork on this car needs to have their limbs chopped off piece by piece.   Quite a list if I do say so myself, but a lot of time was spent just discovering new shit that is wrong with the car and finding a solution or parts to fix it. My last problem that I now have the headache of dealing with is that the exhaust studs on the turbo outlets are M10x1.25 threaded, but the previous owner already put on regular M10 nuts so the threads are... weird. I only found this out the hard way. So now I will just try if I can in any way fit the front pipe regardless, if not I'll have to redo the studs with the turbos installed. Lesson learned for the future: Redo ALL studs you put your hands on, especially if they are old and the previous owners were inept maniacs. Thanks for reading if you did, will update when the engine runs again. Hope nothing breaks or leaks and I can do a test drive.
    • No those pads are DBA too  but they have colors too. I look at the and imo the green "street" are the best.
    • I’m not sure what happened I told them about sonic tunes free OTS tune and the next the I know .. I was booted..   To funny 
    • Yea - I mean I've seen my fuel pump which is decades old and uh, while I'm not saying this with real knowledge... but I sure get the ick at using anything in the fuel system that produced the state of that pump. Many years ago I went through multiple pumps (and strainers) before I dropped the tank to clean it out with extreme violence. I'm talking the car would do maybe 50km before coming to a halt, which resulted in me cleaning out the filter with some brake cleaner and going on my way. None of my stuff ever looked like what came out of your fuel tank. I don't think I'd be happy with it unless every single component was replaced (or at least checked/cleaned/confirmed to be clean here).
    • I'm not going to recommend an EBC pad. I don't like them. Just about anything else would suit me better. I've been using Intima pads for a while now.
