R's Day 2018 : Auto Club Speedway in Fontana : Bluecar Prep


R's Day 2018 is coming to Fontana - Auto Club Speedway on October 6th, 2018.  http://www.rsdayusa.com/

2017 - SpeedHunters


Once again, the plan is to take the Bluecar out.  Since last year, we have been working on a few things for the car. It went to Hoonigan Donut Garage, but other than that just has a few street miles on it.

Doing some light changes. Part of it is done, some parts need to be worked on. 1250cc long nose injectors are in. Have a stock fuel rail that will have to go out to Alex Rodriguez to modify for a -8 feed and return. Have to figure out what fuel pumps I am going to run in this car. The NISMO has Frenchy's, but this car will probably go with some Walboros I bought before I purchased the Frenchy's setup.  Nistune with Flex fuel board is in. Need to install Innovate ECB-1.  Then switch the intake setup around a bit. Nissan/R35 MAF in HPI adaptors connected to the stock airbox.   Have some new suspension that hopefully gets here and installed in time.  Should make the car a little more compliant on the street.

R33 Nissan Skyline GT-R Buyers Guide: 1995 to 1997 : BCNR33

USA and California legal MotoRex R33 GT-R. 
The R33 GT-R debuted in 1995, and is probably the most popular body style in the US. Well at least it was back in 1998 until the R34 debuted for 1999. It's a larger, heavier car than the R32. The biggest GT-R, it is a bit of an odd one out. It is reported to be the first production car to run under 8 minutes at the Nurburgring, but I honestly do not believe that claim. The car they ran had modifications in order to run that number. No matter the claim, no independent testing even got close. Add a tire, an exhaust, and an oil cooler, with the right driver its possible, but box stock, not likely. 

The R32 and R34 use chassis code BNR.  The R33 uses chassis code BCNR.

Early R33 with 97 up headlights and Nismo Wheels
From 1995-1998 there were 16,674 R33 GT-R's produced. About 1/3 the number of R32's.  There are three distinct versions of the R33. The Series 1, Series 2, and Series 3.   Series 1 are 1995. Series 2 are 1996. Series 3 are 1997-1998. 

The R33's RB26 had a few changes from the R32 engine, but overall near the same. It ran a little more boost. You would see about 11-12 psi peak.

Engine and Transmission

The R33 used a carry over version of Nissan's RB inline 6 cylinder engine powered the car. Iron block, aluminum dual overhead cam head. Sodium filled exhaust valves. Solid lifters. Six throttle bodies. Twin turbo. Oil cooled pistons. 73.7mm stroke with an 86 mm piston giving the RB26 2568cc of displacement. Short stroke, low torque, high revving. Stock most of the engines had ceramic exhaust wheels on the turbochargers, and saw about 0.8 bar of boost(500 mmHG, 11-12psi).

Behind the RB26DETT sat a 5 speed transmission, with internals shared with the Fairlady(300ZX). On the back of the transmission was the ATTESA transfercase, or the all wheel drive magic.

Vspec vs Normal GT-R R33 GT-R
Vspec Rear differential R33/R34 GT-R
R33/R34 A-LSD rear differential components

Vspec or victory specification debuted in the R32 GT-R in 1993, and ran through 1994.  The Vspec II debuted in 1994. In the R32 that meant Brembo brakes, 17 inch wheels, stiffer suspension, some ATTESA reprogramming. Other than those parts, the engine, transmission were all the same. No power advantages, all braking and handling advantages.   In the R33, Nissan introduced an active rear differential (A-LSD) in the Vspec versions of the R33 GT-R.  This active rear differential works by locking the rear differential upon throttle application. If your foot is off throttle, the differential is open, making turning a little easier. As you start to put the power down, the differentially progressively locks.  We have seen some people say that the Vspec can vector torque, which it can not. It is just a lockup.

R33/R34 A-LSD circuit diagram


Along with the rear differential upgrade, the Vspec got ATTESA Pro, stiffer suspension. No power or braking upgrades on the R33 GT-R.  All the R33 GT-R got Brembo brakes front and rear.

How to bleed the Nissan Skyline GT-R ATTESA - all wheel drive system

Buy USA legal Nissan Skyline GT-R at importavehicle.com


ATTESA is the all wheel drive system in the Nissan Skyline GT-R.  Hicas is the rear steering. We can't say how many times a week we see people confusing these two different systems.

The ATTESA system is also several different parts. There is a control side, and the actual transfer case. The fluids in the control side, and the transfer are seperate. Nissan says Nissan special power steering fluid in the control side, and Nissan Fluid Type D in the transfer case.  (We normally use Redline High Temp ATF in both systems.)

Nissan Skyline GT-R Fluids
 
In order to get the best performance out of the ATTESA system, it should be bled. Often after a clutch swap, it is not bleed correctly.




  • Locate oil reservoir in trunk and check level. The top line is the full mark. This one is above the high mark.

  • Locate air bleed connector. In an R34 its in a panel under the dash. In and R32/R33 its in the drivers side kickpanel. Connect and disconnect this wire to run the ATTESA pump.

  • Under the car on the transfer case, below the driveshaft, above the line going to the transfer case is a 10mm bleeder screw.

  • Open and close the air bleeder to bleed air out of the system,while connecting and disconnecting the air bleed connector.

Blue Information Plate on Nissan Skyline GT-R


A while back I noticed a car we had, had a additional 3 digit code on the blue information plate on the firewall.  I asked Mark over at GT-R Registry if he knew more about the code.

Facebook post

"On a small percentage of R32 plates, there is an additional 3 digit number next to the Trim code. In the sample it is 203 and the model code is KBNR32RXFSLMAA which means standard (no rear wiper). However as you can see there is a rear wiper (not the best example as the wiper itself has been removed but you can see that there was a wiper there). The reason is because of the 3 digit number, called the personal code.
For series 1 cars, if the first digit is 2 it is audioless (no factory stereo), middle digit is always 0 and for third digit, 2 = fender mirrors (pictured), 3 = rear wiper (as per our example) and 4 = fender mirrors and rear wiper.
For series 2 and 3 cars, if the first digit is 2, it is audioless, second digit is always 0 and third digit could be 1 for electric mirrors or 2 for fender mirrors.
Because this data doesn't appear to be stored in Nissan FAST, it is not available on GTR-Registry.com. It also means that the number of cars without a rear wiper from factory cannot be accurately counted and therefor I have updated the Option code statistics page as well: http://gtr-registry.com/en-bnr32-vin-table.php…"

7.00 @ 199 mph. KingR32 : So Close to 6's



R35's have done it. So far no other all wheel drive car has run a 6 second, all wheel drive pass. However KingR32 from Maatouks Racing in Australia is knocking right on the door. With a 7.00@199 mph pass this last weekend.   Good luck boys, 0.1 and 1 mph for 6's at 200 mph.

Lost Nissan Skylines, A $335,000 Lawsuit, An Empty Warehouse: Has A Well-Known JDM Importer Skipped Town?



We can warn people until we are blue in the face. We can tell them to watch out for Florida, and Florida based importers and cars, but again and again, the same things happen.  Jalopnik writes an article on Steve McCarty and Rivsu Imports.

The allegations against Rivsu come at a precarious time for America’s import scene. For years many of the most desirable Japanese imports were totally illegal to import, barred (with a few exceptions) by our archaic 25-Year Import Rule. It helps explain why this scene is so private, so reliant on word-of-mouth communications, so willing to give a long leash to businesses running with very little communication. The complex legalities and expensive nature of importing lended to the scene a lot of sketchy businesses, fraudsters, outright liars and fly-by-night shops.

Four years ago we warned people about their business actions. When we pointed out they didn't have a dealer license, they went dark for a few months, and came back with one. Then they went through a revolving door of suppliers of cars.  No inventory, trying to sell and store cars that were not legal for years.  They basically had no clue on how to run a car importing business, and this proves it.

Watch out for clueless importers!



Back in 2011 Steve had his illegally imported R33 seized by ICE.  At that time, he asked us for advice, which he failed to heed.  Since he had his car seized, we called him and "his boys" idiots. They didn't like that much.  Years later, Steve tried to deny ever asking for my help. Screenshots even existed in 2011, Steve.

The next shitstorm is the Midnight Purple R34 GT-R's that are currently tied up at JK. The owners of the vehicles as far as we know, have the title documents to the cars. However money is owed to JK, and based on passed experiences with JK, they may never actually get the OBD II working on the cars.  We have a functioning system that we are currently in the final stages of testing. Our prices aren't cheap. We don't give things away. We plan on being in business a while.

Functioning OBD II on an R34 GT-R. 
As they say, those that fail to learn from history, are doomed to repeat it.  Too many illegal car importers out there in Florida, Pennsylvania, and elsewhere that will get that hard life lesson soon enough.

Nissan Skyline GT-R ATTESA All Wheel Drive System Transfercase FX35 and FX45, and RB25 Auto


The R32 and R33 Transmission and transfercase are very similar.  The R34 transfercase while looking and functioning similar is actually a little weaker than the R32/R33 transfercase.

So at one time, after looking and thinking about the GR6 in the R35, and being underneath my Infiniti FX45, I decided that putting a newer transfer case on an R32/R33/R34 might be possible.  I bought a used FX transfer case. I had R32/R33, R34, and RB25 Auto all wheel drive transfercases as we do when we work on these cars for nearly 20 years.

The reason for trying it was pretty simple. Eliminate the electrical to hydraulic to mechanical that is the ATTESA system in the R32/R33?R34.  By using the direct control of a solenoid you could speed the reaction time of the system up significantly.  However once I got the transfers apart, there were a few challenges that I didn't feel like tackling at that time.

I haven't revisited this again, but it is something I would like to revisit.   I have some ideas on how to make it work, and help modernize the ATTESA system.

More write up coming ...

18 x 10.5 +22 Wheels with Staggered Tires on a Nissan Skyline GT-R

18 x 10.5 +22 front and rear. 275/35/18 front and 295/30/18 rear tire

This would be a non standard setup for a Nissan Skyline GT-R. We generally don't like to see a staggered tire setup on an all wheel drive car.  This car is running a 18x 10.5 +22 wheel front and rear. The front and rear fenders are rolled. The car runs an adjustable upper control arm in the front and in the rear.  In the rear there is a lot of room, in the front not much room to the upright. Even some telltales of it making contact. 275/35/18 in the front, and a 295/30/18 in the back. The front tires/wheels already stick out further than we would like in the front, sorry we don't do the "poke." Terrible for aerodynamics, a look for kids and their Hondas. Adults try and keep the wheel and tire within the bodylines.

The smart thing for us to do on this car is to square it up with a 265/35 or a 275/35 tire. The 15 mm in diameter difference is more than we want to see with an all wheel drive car.

What wheels fit on my R32 Skyline GT-R?

Can I run different sized tires on my Nissan Skyline GT-R? 

So, can you do it?  The answer I like to give people is - NO.  The reason is because I don't want them to do something wrong, and screw up their transfer case or ATTESA system, and blame it on me.

The real answer is, if the overall heights/diameters are similar enough, you can get away with different sized front and rear wheels, tires, etc.

There are no specs in the R32 Service manual, but the R35 service manual says

Diameter difference front/rear
0-4 mm STOCK
4-8 mm OK
8mm- and greater NO GOOD

I have seen worn tires throw an ATTESA code. You could get a code running tire pressures way wacky ie 40 psi in 3 tires, and 20 psi in one.

Most often people try and do some kind of staggered setup, don't do the calculations before they purchase tires, and now end up with a 2wd Nissan Skyline GT-R.  Which may sound like fun, until you want/need the all wheel drive.   So always check the diameters, make sure before you buy anything.  The safe way is stay square. Lets you rotate the wheels and tires around the car.
