top speed?

i got a ticket for 269 .
long story short ticket was dropped.

WTF! Please explain the long story!!

To remove speed limiters. Fit Nistune board inside stock ECU. Plug up laptop + Consult cable to Consult plug under dash on drivers side of car, raise the speed limiters via Nistune tuning software on laptop. Nistune tuner / dealer in Canada could do it for you.

Gearing depends on racetrack. If hp racetrack, taller gearing. If tight racetrack, shorter gearing. R32 GTS-T with manual transmission has short gearing at factory (4.363:1 diffhead ratio), so accelerates quickly. Makes it similar to EVO's, etc with shorter gear ratio's, 300hp or so for rally use. It's probably one of the reasons why a R32 GTS-T is faster in Targa than a R32GTR, R35GTR.

R32GTR with stock 4.11:1 diffhead ratio's in front, rear, can fit R34GTR gearbox to work with HKS 25/30 turbo's with stock capacity engine (shorter gear ratio's). I think Mines R34GTR Vpec N1 has stock R34GTR gearbox with R33 GTR V spec 4.11:1 (I think factory are taller, normally 3.45:1) gear ratio diffhead's in front, rear. It explains why the Mines R34GTR has fast acceleration (short gearing). Mines R34GTR does struggle on hp racetracks, as I think gearing is suited to Tsukuba. They used to change the gearing in R32 GTR Group-A racecars when switching from say Tsukuba to Fuji racetracks.

One of my favourites is Signal R34 GTR reaching 300km/h -

The owner of Signal takes it on high speed runs at night time -

ahhh ok so a close ratio gives faster acceleration and wider ratio gives a higher top speed then
and thanks for the info on nistune

Yeah, gearing is why gtst's can accelerate like a whip , and then cruise along the highway at 140 at like 5,000rpm

Whenever I'm on a highway, I wish I had something like a viper that can cruise at 180kmh at like 1900rpm, lol

If the gts-t had a 6th gear everything would be perfect! :P

[Skym]

Final gear ratio in gearbox (5th gear) + diffhead ratio + diameter of wheels = top speed. I think R34GTR stock gearbox has shorter ratio's in 1-4??, but taller in 5th, 6th. Mix shorter gear ratio's in gear box with shorter diffhead ratio in diffhead + 18 inch wheels = quick acceleration.

I think Nismo LSD is around 4.10:1 for R32 GTS-T. 4.10:1 seems to work best with 17 inch wheels, as I think is used on GTS-R Group-A racecar.

Gearbox ratio's are matched to engine powerband. If change engine powerband, change gearbox ratio's to suit.

hit 318km b4 at 6,500rpm(ya things go slow motion lol)

You must have R34 gears (3.54's or 3.45's) because I was at 8300 in 5th for my 300km/h (GPS confirmed) run on a PRIVATE ROAD.

I was at only 265 km/h at 7400 rpm so you got some really shallow gears (and tall tires).

fastest I've gone in mine I think was 289km/h according to my GPS. but I could be remembering wrong and it was slower, I just don't recall.

I do remmeber that I-75 in ohio is FLAAT and boring.

Going 120 on the highway I am usually about 3.1k rpm, hitting the limiter at 180 your around 5.2k rpm.
That is in a gts't.

I wish there was a 6th gear lol.

My rpm's are a lot higher than that. No one knows why though Some kind of aftermarket gearset or something, perhaps :\ My fifth gear is insanely close to fourth, like it's a pure acceleration gear as opposed to an overdrive.

when I first got my vehicle from tyee on the island,,, I decided to wind it out,,, I hit 240 pretty darn quick,,, then I gave my head a shake... I haven't even inspected the car yet...

..got back into town,,, discovered that the fron right tire had a goose egg on the inside wall of it.....

wow was I lucky... kaboom...

Thats weird, I would like to be around 2.4k rpm on the highway, but going 120 its just not possible :/

And no I dont go 20km/h over the speed limit, the speed limit here in SK is 110, not sure about other provinces.

[cortexx]

talking of gearsets etc , how straight forward is the OS gilken 5 speed gear set replacement in a 1995 tranny ?

ANy specialized tools needed ? i'm sure one of you might have carried out this upgrade ?

Where the hell do my posts keep going????
