wow Ive got some work on my hands.

I'm going to clean my car up real good (for the fresh engine), my car is so muddy [X(]. i love cleaning it. anyway i was just reading some posts on the 2speed gearing. is it a straight drop in process? are any mods needed? i was thinking of getting a 2 speed gearing set because they have them on offer for £20 i think the rrp is around £40-50. And having a 2speed...what are the advantages/disadvantages? what happens if you jump and you land in the second gear lol? plus i love the sound of it shifting into second gear

. I think when i get my new engine i will break it in and leave it. because i need to upgrade my diffs. because now i have the money
when i order my diffs shall i buy diff oil and it comes in different watts? [&:] what do you guys run or what should i use?. and should i get after-run oil aswel, i want to try and get the longest life time out of this engine.
