Nissan Skyline GTR Tuning Part 2

Engine Tuning Stage 2
Stage 2 of tuning is where things start to get expensive as we need to upgrade many of the standard systems. Nissan Skyline RB engines are known for the strength and the RB26DETT is the strongest animal with regular maintenance and a safe tune 330+ awkw is possible.

Turbo Selection
Many good turbo options are available for the Nissan Skyline GTR I recommend turbo’s that will bolt onto standard manifolds, this will save time and money in the long run. Popular models include;
HKS 2510 response close to stock with slight power increase
HKS GTSS responsive turbo with max power output of around 300 awkw
Nissan N1, Garrett 2560r, HKS2530 are similar to each other, a good compromise between lag and max power, and 350+ awkw is possible.

Fuel system
The GTR fuel pump and injectors are good for levels up 265rwkw, any more than this and you are starting to push safe limits. Popular upgrades include pumps from bosch, walbro, and tomei. Nengun.com has many injector and fuel pump upgrades available for the Nissan Skyline GTR just remember to choose items which will support your power target and allow some room for future upgrades if need be.

Intercooler Upgrade
The GTR Nissan Skyline intercooler runs out of its efficiency range at power levels above 300rwkw and needs to be upgraded. Many aftermarket bolt on kits are available for the GTR starting at around AU$1000 but as with most things you get what you pay for. Be aware a small decrease in throttle response may be noticeable due to the extra piping and larger core size.

Airflow Meter's
To improve the tunability of the engine its a good idea to upgrade your airflow meter's this allows for finer tuning which will result in smoother power delivery and make it easier for the tuner to produce a higher peak power output . Popular upgrade choices include the Z32 and the Q45. The Z32 is cheaper of the 2 but the Q45 will allow more airflow. click for more information

ECU
If you have not done so already the ECU will need to be upgraded as stated before the Power FC is a popular option due to its price, ease of installation, and use. There are plenty of other options that are superior to the Power FC and allow many other tuning functions like launch control, and the ability to use a map sensor instead of the airflow meter. But the FC is still a popular and is proven to perform.

Head Gasket
Running boost levels above 1.2 may require a new metal head gasket to lower compression and improve reliability. Opinions differ on this subject so I think its best to ask you tuner.

Clutch and flywheel
The stock clutch will certainly fail quickly at this power level the hardest part is finding a clutch that will handle the power yet not make your car a pig to drive. Exeedy seem to be popular and reliable choice and while you are upgrading your clutch a lightened flywheel is well worth considering. This will help the car rev quicker but the trade off is your car will loose momentum quicker to.

Cams
At this stage the Nissan skyline will benefit from a set new cams. The outright power will be increased but the main reason for installing cams is for a fatter torque and power curve. Upgraded cams can help reduce lag, improve mid and top end power. Popular choice is tomei pon cams as they fit without modification and are proven to give good results.

Please use this as a guide only I recommend consulting a professonal before carrying out any of these modifications. Nissanskyline.6te.net takes no responsiblity for any problems you may encounter from following this guide.
