hey there,

as of the other day update the final figures of my GTR mods (2860-5, G4 Link, injectors, pump, 115mm FMIC, profect B, HKS twin, light weight fly etc etc

i didnt want huge KW, torque was what i wanted, and torque is what santa bought me :(

15lbs 240AWKW

18lbs 308AWKW

torque 855 n/m from 3800-7400RPM (redline)

this was a nice safe tune too.......

Sounds great Robbie, must pull haaard!!.

2860-5 turbos look to have similar response to the stock GTR turbos. Only a ~400rpm sacrifice, is this correct?

I ask because I want to replace my stock turbos eventually and was leaning towards the HKS GTSS turbos but your 2860-5's look to be great for response also.

hey bakes

what i have read, is the GTSS turbos will/are more streetable, more responsive, but when you want to go higher then about 330AWKW the 2860-5 are the way to go (cue. correct me if im wrong?) have to ask someone else about them being as responsive as standard, but i would think you would loose a bit of response due to the fact these turbos are larger (cue. correct me if im wrong?)...

CS net

and yes i was quite surprised with the torque, i know the new G4 Link is really tune-able, i just told my tuner to go for max torque, i wasnt searching for mega KW's

hope this is some help......

Sounds good donkey.

For those interested this has been my experience on r33 gtr's.

Standard turbos are all in by ~3500rpm

GTSS- ~3700rpm

2860-7 ~4000rpm

2860-5 ~4600rpm

These figures are when the car starts really moving, not just when full boost is just reached as there is usually a slight delay.

Some people may have made them slightly more responsive with tuning.

Anyone managed to better these? If so, with what supporting mods/cam timing etc?

yeah the -7 are the same/similar to the GT SS......

most people say if you want torque/response go the GT SS, i dont know how much torque the GT SS turbos on my set up would produce, i would be keen to find out, i know they would have better response, but torque?

but dam i spent alot to get these beast's to work, i think looking back on it i would have gone GT SS, just the mods/gaskets etc for the garrets gets expensive, and the supports to make them work is alot of coin......to get the full potential out of them you really want to go 20lbs+ and then you need to mod oil pump, sump, returns, prob go forged god the list goes on.....

The 2860-7's are more responsive than the 2860-5's yeah? Aren't the 7's a smaller turbo?

I'd like to see a bar of boost by mid three's... Who know's if I'll get it lol.

Yep the -7's are smaller. Hence they come on boost earlier but make less than the -5's in the top end.

hmmm

correct me if im wrong, but if my max torque figure is starting at 3800rpm wouldnt that mean that they are running at full boost?

robbie

Absolutely... I would suggest the scaling on the dyno graph is incorrect or the ramp speed of the dyno was set very slow.

Next time you drive the car watch the tacho in say 3rd gear when you can actually watch the transition and see when it hits full boost and when it starts really going. That will be the point its actually making peak torque.

Wherever peak torque is, you'll have bucket loads of pull. I would be very surprised if -5's were pulling at 3800rpm.

Let me know when you have a chance to feel on the road where it actually picks up.

Remember on the dyno you can create excessive load that you would never see on the road making boost ramp up far quicker than it could on the road.

    • 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.
