There is a lot to learn. Including the golden rule:

Searching is your friend.
Before you post a technical question, be sure you have done keyword searches for the topic you have a question on. Nobody wants to answer the same question over and over again. Most every SE-R question can be answered by browsing the pages on this site, or be found on pages linked from this site. The 3-day waiting period was enacted because people refused to make an honest effort.

The next thing to learn would be posting in the proper section. This is the turbo section, I'd say your post belongs in General SR20, since none of your questions are related to turbo.

I'm not trying to flame you, but others won't be so reluctant to do so. Start with your tranny problem. It's been discussed a million times here. Here you go:

Please search before posting any more questions. Also, please type in somewhat coherent English. I couldn't understand half your post.

^^ this is gotta be fake..?

What you need on top of those headers is a dual quad intake manifold and the Tk421 modification.

Dude, do a search before asking the above questions. You might get "flamed", badly. 5th pop out has been discussed. Again, please search next time.

These responses have been very nice, consider yourself lucky. SEARCH!!! If you don't search for these problems then maybe in your next thread we will be out for blood.
