CAS doesn't do anything to the timing (in terms of adv / ret). It simply lets the ECU know where TDC and each of the 360 crankshaft degrees are. It certainly fits and works on a RB20DET.
Sorry, can't help you with the TPS.
We've just been discussing it here: http://www.skylinesaustralia.com/forums/topic/351472-catch-can-install-is-this-the-right-way/
(Yes it's a 25, but the principle is the same)
What you are proposing is illegal because it vents fumes to atmosphere. The alternate solution keeps the system sealed and recycles all gasses / fumes.
Fred Gibson removed the HICAS from the race cars because it had the nasty habit of turning the car around if you backed off halfway around a corner. Not an ideal situation on the racetrack.
NEVER believe the odometer of a car delivered from Japan.
Pretty sure that won't work. You still have it set up so that oil and oil vapour can be sucked into the intake side of the turbo, particularly under boost (high load) conditions. And that is exactly when you don't want it to happen.
The PCV valve only opens under high vacuum (low load) and detonation from the oil vapour isn't a problem.
How old is the battery? Skylines aree notorious for being sensitive to voltages. Older batteries take more current to recharge after a cold start, and most of the ECUs view this as a problem, and misbehave accordingly.
Do you have same size tyre / rim combo on all 4 corners?And my money is on the throwout bearing (should have been replaced when the OS giken was installed).
I'm pretty sure the engine bay isn't anywhere long enough to accommodate 6 cylinders. A grunty little 4, along the lines of the CA18, is likely your best bet.
But then you need to worry about how to make it stop. And turn corners. Maybe address those problems first.
Sounds like the solenoid on top of the starter motor has jammed. In "old school" fashion, use a bigger hammer and give it a jolt, see if that frees it up. But first, chek that the starter wire hasn't disconnected from the solenoid.
Unless you fully understand the principle for the usse of a thermo fan, and know how to properly install it and properly operate it, stick with the factory setup. I'm sure Nissan knew what they were doing when they decided on the use of the viscous clutch type against a thermo setup.
Looking at the spec sheet for Toyo's Proxes 4 (most manufacturers would be similar), the recommended max width for a 245/45x18 is 9", and for a 225/45x18 8.5"
No it won't! The ECU only runs for about 5 seconds when you turn the key to IGN, just to pressurise the fuel system.
Back to OP, I had mine off the road for about 3 months, still ran fine when it finally got re-started.
Not so much concerned about the diameter of the disk, more concerned about the diameter of the pistons in the calipers. Larger pistons will require more pedal travel, or a bigger diameter master cylinder.
Anyone know how the piston diameters compare?
