Running My Gtr On Better Fuel

Heading back out to WSID next wednesday armed with a decent wheel/tyre combo . On paper from the previous runs the car has a 10 in it with current power (just under 350kwaw on CRD's dyno) . I wouldn't mind having just a little bit more power to make the job easier . The thing is I'm running gt-ss turbos at 1.4bar so I haven't really got any head room here as this amount of boost is pretty much it for these turbo's . I was thinking about getting the car tuned on some better fuel I don't really have a big understanding on the race fuels what should I look at using and what type of gains can be had?? . I'd be happy with a 20kw gain at the wheels just to make my job a tiny bit easier .

Simply adding C16 won't do the trick. You'd be better off buying one of the many racing unleadeds and having the car tuned to suit. It's not all about the octane rating of the fuel though as some race fuels will burn quicker than pump and require a richer setting on your fuel maps. Only then will they be able to take the added timing and make some more power.

Out of interest, C16 has its place but IMHO it's sure as shit not in a street-driven RB26 like yours. It's a leaded fuel which has implications for O2 sensors, catalytic converters and the EPA, the last of which comes with a free multi-thousand-dollar fine if you're busted running it on the street.

I never knew C16 was leaded.... I think Elf makes a decent high octane

yeh C16 is out of the question . Spoke to Jim at CRD yesterday about maybe tuning the car on vp109 or something similiar for next wednesday but he wasn't too interested in doing it .

Find another tuner?

i definitely wouldnt look for another tuner - im sure the likes of ppl that have been around for quite some time such as paul (dirtgarage) will agree with me that jim @ crd is the beez kneez of tuning :D

the problem you will also have is that your power fc will be locked by jim which means that if another was to retune they would need to initialise.

run a nos shot :ermm: that will give that edge you're looking!

seriously though, you want to run a 10 on pump fuel so that you can tell your mates that it is a street car with street tune. thats my angle anyway

      You just need to remove the compressor housing, not the entire turbo. I would not be drilling and tapping anything with the housing still on anyways.

      Mistakes were made, my R34 Story

      By Kinkstaah · Posted

      So, I put my boat on a boat. First of all, I'm going to come out and say it. Why is Tasmania not considered a holy goal, an apex that all road-legal modified cars go to, to experience? This place is an absolute wonderland of titanic proportions. If people are already getting club runs for once in a lifetime 30 person cruises to Tassy then I've never seemed to see it. It is like someone replaced the entire place with an idyllic wonderland for cars, and all of the people living there with paid actors who are kind, humble, and friendly. Dear god. After doing a lap of almost all of the place I've found that it's a great way to find out all of the little things that the car isn't doing quite right and a great way to figure it all out. All in all, I drove for 4 hours a day for a week and nothing broke. I didn't even need to open the engine bay. This is by all means a great success, but it has left me with a list of things to potentially address. I also now have a 3D printed wheel fitment tool which annoyingly hasn't got any threads in it to actually assemble it. I might be able to tape it together to check the sizing I actually want to use, but it'll likely involving pulling the shocks out to properly measure travel at least at the front, and probably raise the car while I'm at it, at least in the rear. I scraped on quite a few things and I'm not sure how else to go about it. I was taking anything with a bump at what felt like 89 degree angles. And address those 10 other tasks. And wash the car. God damn it is dirty. And somehow, the weather was perfect the entire time - And because I was on the top of Mt Wellington it turns out it was very much about to freeze up there. I did something I typically never do and took some photos up there in what must have been -10 and the foggy felt like suspended ice, rather than mere fog. If you own a car in Australia, you owe it to yourself to do it.

      R32 gtr transmission strength, billet plate

      By cosline · Posted

      Hi, I have a r32 gtr transmission. Does any of you guys have an idea how much power it will hold with the billet center plate and stock gearset? At what power level and use did yours brake with or without billet plate? Thanks, Oystein Lovik

      Spotted on the street....

      By Rezz · Posted

      Saw this replica police car based on a Mitsubishi Starion XX parked next to a 'police box' (it's literally a box) in Hirohata, Himeji City in Hyogo prefecture the other day. It's owned by Morii-san who is a local Mitsubishi Starion enthusiast. According to a local radio station blog post, he always wanted to make a police car himself based on ones he saw in his favourite Manga comics.  As it's illegal to modify a car to look like a police car and drive on the road, Morii-san tried many times to get permission from Aboshi police station headquarters nearby. They refused initially by after they got tired of that they granted him permission. However, the car can only be displayed on private property and obviously can't be registered as long as the police livery is present. The car was completed at a cost of 1.5 million yen (US$ 10,000) in addition to the car cost. A location was chosen outside Hirohata Police box where the car can easily been seen from the street. Morii-san has two other Starion road cars, both widebody GSR-VRs.
