hey guys i crashed my r33 drift car. im stripping it but i have decided to keep the engine and gear box to put in a 180sx. funds are low so it wont be till mid next year before i get the new car up and running. the motor and gear box are out of the car sitting on my garage floor covered up and have been for about 3 months now. MY question is what should i do to protect the engine while it sits for so long to make sure its all good when i finally get it going again? thanx guys

Put the engine on an engine stand.

Leave oil in the sump. Turn it on it's side once a week to get the oil to soak up to the pistons and pins, straighten it up. Spray 2 seconds of WD40 into each spark plug hole and replace the spark plug. Rotate the engine 3 times, once a week after you have done that.

Cover up the intake pipe when done. Glad wrap and electrical tape will do. Don't shove rags in there as they tend to get forgotten about and can get sucked in later.

The WD40 will stop the rings from binding and rotating it will keep them from sitting in the one position in the bore

None of this is necessary but will ensure it stays lubed and internally rust free and smoothly operating for a long time.

Yer I don't know how you plan to do an RB25 conversion in a 180sx if you can't crank an engine over by hand...

1. Go get a nice torquey ratchet

2. Stick it on the bottom crank pulley

3. Elbow grease

Steves got a point. good way to find out the answer to a question is to ask.. The bolt through the centre of the balancer, turn that sucka. this turns the crank around which will turn everything else connected to it. Had your weetbixs?

If that were to happen, then there is another problem. There shouldn't be enough slack to do that

no not necessarily, iv seen it happen on cars that havnt even done there 100000kms timing belt change. its one of the main rules your taught when becoming a qualified mechanic. the engine is designed to turn one way, not both.

If it has slack to slip on the crank when turning anti clockwise, then what do you think happens when you turn the belt clockwise? The slack moves to the other side. Therefore, it would be far too loose.

Yes the 'engine' is designed to rotate one way but no the belt is not. The belt has a rounded tooth design and it doesn't matter which way you rotate it, it will have equal possibility of slipping either way.

Also the tension on the belt does not change, if you rotate it clockwise, the tension is on the idler side, if you rotate it anti-clockwise, the exact same tension is on the tensioner side.

    • Yeah, that's fine**. But the numbers you came up with are just wrong. Try it for yourself. Put in any voltage from the possible range and see what result you get. You get nonsense. ** When I say "fine", I mean, it's still shit. The very simple linear formula (slope & intercept) is shit for a sensor with a non-linear response. This is the curve, from your data above. Look at the CURVE! It's only really linear between about 30 and 90 °C. And if you used only that range to define a curve, it would be great. But you would go more and more wrong as you went to higher temps. And that is why the slope & intercept found when you use 50 and 150 as the end points is so bad halfway between those points. The real curve is a long way below the linear curve which just zips straight between the end points, like this one. You could probably use the same slope and a lower intercept, to move that straight line down, and spread the error out. But you would 5-10°C off in a lot of places. You'd need to say what temperature range you really wanted to be most right - say, 100 to 130, and plop the line closest to teh real curve in that region, which would make it quite wrong down at the lower temperatures. Let me just say that HPTuners are not being realistic in only allowing for a simple linear curve. 
    • I feel I should re-iterate. The above picture is the only option available in the software and the blurb from HP Tuners I quoted earlier is the only way to add data to it and that's the description they offer as to how to figure it out. The only fields available is the blank box after (Input/ ) and the box right before = Output. Those are the only numbers that can be entered.
    • No, your formula is arse backwards. Mine is totally different to yours, and is the one I said was bang on at 50 and 150. I'll put your data into Excel (actually it already is, chart it and fit a linear fit to it, aiming to make it evenly wrong across the whole span. But not now. Other things to do first.
    • God damnit. The only option I actually have in the software is the one that is screenshotted. I am glad that I at least got it right... for those two points. Would it actually change anything if I chose/used 80C and 120C as the two points instead? My brain wants to imagine the formula put into HPtuners would be the same equation, otherwise none of this makes sense to me, unless: 1) The formula you put into VCM Scanner/HPTuners is always linear 2) The two points/input pairs are only arbitrary to choose (as the documentation implies) IF the actual scaling of the sensor is linear. then 3) If the scaling is not linear, the two points you choose matter a great deal, because the formula will draw a line between those two points only.
    • Nah, that is hella wrong. If I do a simple linear between 150°C (0.407v) and 50°C (2.98v) I get the formula Temperature = -38.8651*voltage + 165.8181 It is perfectly correct at 50 and 150, but it is as much as 20° out in the region of 110°C, because the actual data is significantly non-linear there. It is no more than 4° out down at the lowest temperatures, but is is seriously shit almost everywhere. I cannot believe that the instruction is to do a 2 point linear fit. I would say the method I used previously would have to be better.
