Nissan Skyline GT-R Transmissions and Upgrades for Nissan Skyline GT-R and GT-R parts.

Transmissions with and without transfer cases
Transmissions with ATTESA transfercases attached
There were two main transmissions used in the Nissan Skyline GT-R's from 1989-2002.  The R32 and R33 used a 5 speed transmission from Nissan(FS5R30A), and the R34 GT-R used a 6 speed transmission from Getrag(V160). The FS5R30A is very similar to the 300ZX transmission internally. The Getrag is similar to the transmission used in the MK IV Toyota Supra. The input shaft and main shaft are unique to the GT-R on both transmissions, the rest of the internal parts are interchangeable.

Below is some information I have gathered though the years about Nissan Skyline GT-R transmissions. Not all the latest stuff is on the list. There are a few more PPG options now, few more other things you can do, but most of the information is good. All wheel drive cars are hard, hard, hard on the transmission. When the wheels don't slip, the hard parts break. Third gear is a big one in R32/R33. Bang third gear hard, and it will let go. Some people say the late R33 box is stronger, but I have tried them all, and broken them all. Once, twice in a week in a 500 hp R32 with a nasty clutch(unsprung HKS/Tilton). You want a sprung hub, you want to run Redline Shockproof Heavy gear oil in most trans(not the V160).

The Getrag is loud at idle. The synchros aren't that durable. Even though the Supra guys run them pretty hard, we break weird hard parts in them. Sequentials take some getting used to. Fun, but you have to treat them like a race box(which they are). They require frequent rebuilds if you are 1/2 way serious. Some gearboxes have helical cut gears, some have straight cut gears. If its a street car, or you ever really plan on driving it on the street, do yourself a favor, and get helical cut gears. I put about 2000 street miles in an R32 with a PPG trans. Straight cut, dog engagement. The whine from the gearbox cruising on the highway way pretty annoying. Louder than the 4 inch exhaust, and the Weldon fuel pump.  Your mileage may vary, but the pitch and tone of it, isn't a good sound for a long time.

Exploded Single Plate Clutch : R34 GT-R

Exploded Single Plate Clutch : R34 GT-R

Single plate multi puck clutch  for an R34 GT-R that came apart.  Hard to say what happened exactly without data logging, but over revving an RB26 is pretty easy. 8,000 RPM stock, shifting with the left hand. Always possible. Went though the bellhousing and into the floor. I like multi-plate clutches.  Even better - Tilton carbon/carbon clutch. for Nissan Skyline GT-R and GT-R parts.

FIA Group A NISMO Nissan Skyline GT-R Homolgation Papers

FIA Group A Nissan Skyline GT-R paperwork

The NISMO Nissan GT-R was homolgated for Group A racing 1-31-1990. There are lots of people that call the "aero" parts N1 parts, but the NISMO came before the N1 car, so these are NISMO parts. for Nissan Skyline GT-R and GT-R parts.

RIPS Racing RB30 Powered Nissan Skyline Goes 7.64@182 MPH

Now with In Car Video

RIPS Racing in New Zealand, has set a personal best in their drag car, MGAWOT III.  The RB30 powered, and powerglide equipped R32 Nissan Skyline GT-R went 7.64 @ 182 mph. The car is moving. They see the 7.41 of the fastest GT-R in the world - Heat Treatments R32 GT-R in their sights. Rain seems to have cut the event short.

 Lets put in a soft tune just to get a qualifying number on the board. BOOM 7.64 @ 182 like it was on rails. The changes we've made to other areas of the car are obviously working well to get a pb with the power we had in it. Then the rain came. for Nissan Skyline GT-R and GT-R parts.

Illegal Street Racing in Okinawa Video

Road and Track picked up this video from Japan, about illegal street racing in Okinawa. I might know some of the cars featured in the video. Look kind of familiar. We just had an R32 NISMO come in from Okinawa, it knows these streets.

Okinawa is a stronghold for car enthusiasts and Nagayoshi-san is a well known name in the local car scene. He has been drift and drag racing for decades. Recently, most of Okinawa's race tracks have been shut down, which leaves Nagayoshi and his pals just one race on the streets of Okinawa! Nagayoshi's car is taken directly from the racetrack to the streets, 1000 horsepower and over 330km/h keep the adrenalin pumping. In the spirit of Paul Walker and not Justin Bieber's pathetic attempt on racing, Vice presents Okinawa's illegal street racers.
