Lets put it another way minimum legal tyre on 9.5 rim is 245 so really the answer for the OP is have a think before you "pick up" some wheels and consider whether they will actually fir you car. Alternatively you will have to do what it takes to extend your guards.
I can't see any reason not to transport a drum on its side except that it is weaker that way and may get damaged or roll off the deck . However you should probably check your regulations to see what they specify. I must say all commercial carriers keep the drums upright and in NZ at least that quantlty would require Dangerous Goods placarding and a licence for the driver. Also the weight of a full drum would require proper restraints to be used.
The build up of pressure that need to be relieved seems to be more on the inlet side. My catch can is about 3L and by the look of it the max level would be about halfway and since I fill with 6L of oil I don't see it emptying the sump. And yes an extended sump with baffles and gates would be an added safeguard.
^^^what he said. Pull the thermostat out and if it's stuck open it's obviously dodgy. I hope it's not one of those Nismo low temp thermostats. If so bin it and get a stock one. The Nismo radiator cap "shouldn't" be a problem.
^^^what he said. Once you have removed all the bell housing bolts and the starter (and the front prop shaft) undo the rear g/box mount (put a jack under it) and lower it down as the engine goes up. Not one man job - you will need help!
Obviously first remove the radiator, fan etc.
Stock intake manifold and throttle body will get you to your target hp. But if you have already bought the Greddy copy and 80mm throttle body and would rather install it than sell it go right ahead.
If you start it up from cold and let it idle you just feel the top hose and when the thermostat opens it will suddenly get hotter. Of course this will not be the case if your thermostat is stuck open. In this case it will just slowly get warmer.
If your bleed valve does not work clean it out until it does work. Where exactly is you temp sensor for your aftermarket gauge? I cut the top hose in half and put an adapter in there.
Have you checked that the thermostat is working correctly by say letting the motor idle and feeling the hose to see when it opens? In fact at those temps (if correct) the thermostat should not open. I would be inclined to pull it out and see if it is stuck open. Or first get another view of your water temps by say putting a thermometer in the radiator filler or using a laser gun type thermometer.
Running that cold is not ideal.
I just cut two pieces of timber with a suitable bevel on one end and drive up on them. They also double as wheel chocks so you don't have to use the handbrake when the brakes are hot
At the top of this page the second "pinned" thread is about the computer controlled LSD in the back of your V-Spec. If you read all of it (its not too much) you will find out how to service your diff so that it works properly. If you can afford it now wold be a good time to put a Quaife LSD in the front of your car (available from Palmside in Christchurch NZ) and if you have the time and inclination there is information in this section on how to beef up your transfer case (with a GTR the spending never ends!)
