hi there,
i have not long owned my 92 gsr (full evo 3 rep) for very long and a few things have came about that i would like to know about,

1) Can you get to the gearbox without removing the engine?

2) Last night i was coming down my drive and the car sort of dies for half a second then comes back on, showing the check engine light and the turbo light? does anyone know why this is? (i am going to take it to get a diagnostic test in the next 2 days)
maybe to do with alarm or turbotimer?

3) What is the work involved for the thrust bearings? They rattle a bit when clutch is out but stops when the clutch is put back in, also when driving it makes a bit of a whine/small grindish noise, could this be to do with the thrust bearing also?

4) Gearbox not as smooth as it should be, what can i do to make it have smoother gear changes?

5) tappets in morning are a bit noisy, ive got some stuff to put in with the oil though that should quieten them down a bit

6) Rust in the roof.. can you get away with a sand back and bog or do you have to do the whole roof chop?

any answers to any of these would be much appreciated
