With a 12AT producing an estimate 260 fwhp I get high 12 second passes.

yea i plan on doing a freshen up on the engine first, then probably a weber carb, ive always trusted weber over just about any other. then i dunno what size turbo i want yet, something not too big, maybe a 60-1 
unless you guys can recommend something else, cause i know **** about turbo carbed cars, this will be my first attempt at something like this, so any suggestions from knowledgable people will be helpful
ps. forgot to ask, where in the hell would i find a turbo mani for a 12a? thanks

ps, doesnt have to be gas freindly or user freindly, just fast

12's will be ez to hit with 250ish hp and some good tires.....there are afew diff ways to go about turboing your 12a but 250hp os about the most you can get from a stock port well250-300hp 300 being the maxxxxxxxx the exhaust wont flow enough being stock...more or less you can just throw a stock turbo 2 set up on there and keep yoru stock carb just get it set up for blow thru...or i have a turbo manifold t3, waste gate, bov, side draft manifold..you just need to get IC t3 turbo and a side draft carb

ugh ps again... 9im a question asking sob tonight) will a stock 13b t2 manifold bolt to a 12a? and is it a t3 or t4

with a large street port and full race port exhaust and the right torbo and mods you can hit in the 600's hp... and kill mid 12's..if all you are wanting is 12's...get a stock tII manifold and turbo do the waste gate mod. have some1 set up your stock carb for blow thru and yous the stock ports...with ou good tires you will find you new found power useless if you not in a 3rd gear roll

600hp with just those mods? 
i was thinking like 400ish, just a street port, exhaust, smaller turbo running 8-10psi, and maybe an fmic... im not saying im aiming for 12's, ill take whatever i can get, more or less, im just building ans seeing where it goes i guess, though at that rate might have to upgrade that stock tranny too lol, go with a ford t5 or something i guess, get the 8.8 while im at it. right now all of my income pretty much is going towards my car, and this build will be a year long project im sure, but i have nothing else to do, in college again and my work schedule is kinda messed up but i have a good bit of free time to work on it, ill keep you guys updated on it, though *cough* *cough* i dont even have the car yet... 
ugh, ive "almost gotten 3 fb's in the last 2 weeks, and all 3 the people either backed out, or informed me wrong... been pissed but i have another one lined up, lets hope 4th times a charm

im a believer in a heavy fly wheel. it takes a lil more to get it going but it doesint drop in rpm as much and if gives a lil more grunt...light flywheels do free up hp but they drop rmp much faster..with a turbo car and a heaver flywheel it will help keep the turbo spooled for the rmps not droping as fast. but there is no right or wrong answer to witch is better every1 think something diff

I've seen test results posted by Fidenza for thier light weight flywheels. The lighter ones actually produced better ET's, though not by much.
My toughts/theory on this is: A heavier flywheel gives a better launch, then it's benifits are done. Everytime you shift, the energy that was used in winding up the flywheel is lost between the shifts and starts over. The light weight fly takes less energy to spin up, so less is lost between shifts. This applies to drag racing. Street driving has a different comfort level. I have never driven a car with a light weight fly, but I cannot imagine how much of a pita one would be with no low end torque that I have, or lack, in the bp now.
