So my R34 GTR with GTSS', poncams/gears, Z32s, pfc, HKS/Nismo dumps-pipes-zorst, bigger cooler, hard pipes, profec, splitfires, etc. made a poor 290awkw with some serious boost issues. Big plug to Unigroup who seem to have sorted the boost issues that i struggled to find on my own...

Now i am up for a decent retune and am seriously considering jumping on the E85 bandwagon, since there are some good supporting mods to start with. My fuel setup is all Nismo, including intank pump, 600cc inj's, and reg. I was thinking bout upgrading to 1000cc ID's, running E85, 22psi+, and aiming for mid 300's at the wheels.

What do you guys think of running the Nismo intank with 1000cc ID's to support the power level, and also doing it on standard bottom end?

Id be getting a small undercar surge tank and one 044 pump or similar should do the trick for that power level..Only cost about 300$ too, cheap for peace of mind..

If you get the latest PI magazine theres a story on it, and a free dvd... :D

If we're talking only one 044 pump, wouldn't the Nismo pump be close in flow rate comparison?

i cant see why you cant make 300-330ish with the setup you have on just 98.... is the extra 20-30kw really worth screwing round buying e85 all the time? Unless its at a servo near you... or the car is track only....

In the perfect world it would make 330awkw, esp with all the brand name bits on it... It only made 290 and drove like a pig, although the old tuner was clueless and ignored the boost issues too. Just want to make sure it reaches its potential, and the possibility of it exceeding expectations and making something silly like 370+ would be insane!!

Servo in the next suburb is selling E85 as of next month.

Sard 700's (or the 800s) would be fine for that power. Minor rail bump if anything.

I think Nismo have 740s for RB26's as well?

Nismo pump flows fine for 400rwkw on PULP/700cc + a minor bump (circuit cars, no surge tanks in them)...

So E85 @ roughly 360rwkw would be similar in terms of volume/supply

Most you'll get is around 30-40rwkw gain from E85, going by what most other results indicate at least anyway :D

So 370 would look like the limit (in theory).

You could always put a big single in tank like an A1000 for that power it shouldnt be stressed and then no extra lines and tanks etc

Thats an 800$ pump, for that you get 2 44s and a surge tank...

Maybe I just like surge tanks, but thats how i was going to set mine up anyway..

You dont think its worth it?

:D neither does nismoid.....

By any chance do you get your car serviced at Autostyle? I sort of recognise the plates

Most people will say you need an extra 30% for E85, thats not always the case, my car proved it was way more than 30% under full throttle, but then again every setup is different :D

^ depends on how efficient the setup is and all the usual variables that come into account :D

Some cars respond much better to fuel and all of a sudden you can get heaps more out of it, same token fuel use then is higher also.

Here is the link to Caltex planned rollout of E85:

http://www.caltex.com.au/ProductsAndServic...s/BioFuels.aspx

Marketing manager told me plan is have most running by late September, early October. So that might make it easier for some.

Engine bay looks almost stock, i don't want the look of pumps, lines, surge tanks in the boot.

The 740's are side feed Ash. From what you describe pump maybe close to a dangerous limit there.

You mentioned unigroup fixed your boost issues, what sort of power is it making now?

The car should be making in the region of 320-330awkw with the hardware you have currently, and if not, somethings not right and I would be addressing that before trying to chase more power through switching to E85.

Haven't been back on the dyno, currently sitting outside holding off for a week to decide whether or not to go E85.

    • 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. 
    • 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.
    • Damn that was hilarious, and a bit embarrassing for skylines in general 😂 vintage car life ey. That R33 really stomped. Pretty entertaining stuff
    • 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
    • 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.
