Another turbo size question

[hyboost]

I really need help deciding which turbo to install. I've gone through as much info as possible, rehashing as much info as my small brain can manage & I've about given up. I asked a question, what would I see more 1/4 time improvement doing, a new intercooler or a bigger turbo? Seeing I have an Alchy kit installed, I was advised by a good source that a turbo would be the answer. This car see's mostly street miles, going to the track 9 or 10 times during the summer. This is purely a summer driver, as it's only driven in nice weather. I am running a TE49 now, running 11.8 & 112 mph on avg. Usually a 1.6-1.65 60ft. 1/8 is 7.5 @ 89 mph. I have installed a small cooling fan in front of my stock intercooler, to help prevent heat soak when waiting in staging area, between runs. I really don't want to go with a BB turbo mostly because of the price. I was hoping to keep it around $800-$900 range. I am installing 60lb injectors & a T tweek chip. So,,, what turbo is going to get me low 11's,,, high 10's? Is this realistic? Or am I better off going with a bigger intercooler even though I am spraying alchy on my stock IC? See my sig for mods, they are all the standard stuff. Only thing internal was a cam(202-202 duration) & H.P. valve springs. Sorry so long but Wanted to give as much info out as possible & not write a book. Thanks a lot. Ken F. Lancaster NY.

Tough one to answer definitively. Let me just say what I believe from my own experience. First off, you want to run 10's and you definitely race it more than your average street guy.. you have a trans braked tranny.. Everything you mentioned has and can be done.... I just don't do it that way. I would use at least a 61-p trim, preferably ball-bearing. I would also use some kind of an upgraded IC, just because we need to be able to flow the air through it.. The benefits of these upgrades is you will see better all around spoolup, better performance getting into boost, better bottom end and the ball-bearing option will match up better with your current torque convertor.
