To even come close to answering that we need to know the year, make, model, engine and accessories on the vehicle.
As long as you put in exactly the same as what came out. Go by vin # engine code. Eg: if you take out a 2.2 OHV put another 2.2 OHV back in, not a 2.4 or other.
To put the camshaft in takes a few minute. To strip down the engine to the stage where you can fit the camshaft and then rebuild it can take several hours.
One hour
for as long as you take care of it.
You take one engine out of a car and put another one in. Done.
It can take 2 hours to put on a space suit.
Yes I have put many into golfs before. They fit fine but you do need a engine lift and some patience. Its a long process and will take you the better part of a weekend.
Depends on how well you take care of it I have seen them go up to over 300000 miles. But to put an average to it on a normal(non-M car) BMW engine 200000. with no major engine issues.
As long as you lube up.
1 take out the engine 2 put a new one in duhhhhhhhhhh
It can take 2 hours to put on a space suit.
Don't. An Rx-7 is a perfectly balanced car with its lightweight, smooth accelerating rotary engine. If you take good care of it, it will take good care of you. If you want to put in a different engine in it, a corvette engine is the only way to go.
