Nissan GT-R R35 F.A.Q. - The five questions posted most recently:

From DarinF on the forums: "Question, have you guys installed blow off values on the new Gt-R? I heard the way the new GT-R's turbo system works is that it sends the excess air back into the system (I have no clue, just want that cool air sound in my car!)

Answer:� I would not recommend an aftermarket blow off valve that is vented to the atmosphere on the GT-R. This is because the GT-R is mass air flow metered.� So, when the car shifts gears, it blows off air that has already been metered and the ECU still dumps in extra fuel in anticipation of the extra air.� When the air blows off, the fuel still is delivered and the car runs rich.� This causes stalling, pre-mature spark plug fouling and excess carbon build up.� If you recirculate the blow off valve air back into the intake system, everything should be fine.� However, the stock bypass (aka blow off) valves appear to be fairly large and should do the job up with the boost pressure raised slightly.

What are the differences between the USA-spec and Japan-spec GT-R?

Wed, 11 Jun 2008 16:46:00 GMT

- The seat base is larger on the USA-spec GT-R

- The USA-spec GT-R shocks are stiffer, but the springs are softer rates

- The USA-spec GT-R has revised transmission/differential mounts for less wheel hop

- The side markers are clear on Japan-spec and amber on USA-spec

- Japan-spec cars are right hand drive, and USA-spec cars are left hand drive

- The Japan-spec GT-R has a 112mph top speed limiter, but the USA-spec GT-R does not

- Exterior paint colors have different names, but are the same colors

- The Japan-spec GT-R offers a 'Black' package, which includes red seat inserts and interior accents

What is the first issue I may run into when increasing the power of my GT-R?

So far, the only major issue that has been reported is that around the 650 horsepower level the clutches inside the transmission start slipping.� There should be an upgrade available for this problem soon.

Is the GT-R transmission a manual or automatic? How does it work?

Mon, 03 Mar 2008 06:33:00 GMT

Contrary to what most websites and magazines report, the GT-R's Borg-Warner/Aichi manufacturer transmission/trans-axle/differential combo is actually set up just like a conventional manual transmission but with dual 'wet' clutches (one for even gears and one for odd gears to improve rev matching on downshifts) that are solenoid controller which gives it an 'automatic' type operation without the use of a conventional shifter. There is NO torque converter, valve body, etc. It is a true "manual" type conter-shaft/meshed gear transmission. We feel that a more appropriate term for the transmission would be an 'automated manaul'. It is similar in operation to the 'F1' transmission option on newer Ferraris. The stated shift time is 0.2 seconds between gears, however it has been stated by a Nissan rep that it is more like .06-.1 second when on the transmission's user selectable 'R' setting!
