Ok i need to figure out what size turbo i should be looking for. The car is a 91 se-r the block is going to get redone with a girde. I was thinking of getting, pistons, conectiong rods, and the crank checked. Also i was going to get the head flowhoned, valve job and new valves. The car will be street driven. Another thing that i would like to do is incorporate Nos in the car to may be a helper for a larger turbo to take care of lag. Because of the street driven it needs to run on 91 or 93 octane pump gas..The Hp i would like to be at is 400 or around there if traction is a real problem less would be ok. thanks this is the EDIT with some new questions answered..

Oh man, slow down man, I have a headache, hot tip, PUNCTUATION.

What is your power goal? What will the car be used for? How much lag is ok?

Um... okay, first of all the SR20DE already has a girdle. Who told you you needed one? Second, what kind of pistons? What CR? Why are you getting new rods? I mean, how much power are you planning on making?

You have to give us more information before we can give you advice on what to do. You have to tell us how much HP you want, how much money you have and you have to be as specific as possible.

Yeah.. More info!! Seeing as how the sr20's stock bottom end can handle up to 400hp without modification, are you planning on going crazy with it?? I just bought a t3/t04e .63 that i'm planning on using on my stock bottom end, probably pushing around 340 hp or so... how much hp do you need?? Are you planning on having it as a daily driver??

Ok the list is redone.. please take a nother look at it
