tb is drive by wire, u have to get a fast 90 tb or holly etc.... that has a cable setup. i also think u have to extend the wiring pigtail for the map cause is up front on the ls2. i'm not sure about the fuel rail though..
Silver is right. You'd have to buy the LS2 intake, and buy a $400 throttle body. You would also need a fuel rail mount kit and extend the MAP harness. All this for the same, or worse, than LS6 intake performance.

I put a ls2 intake on my 98 ta and could tell a huge difference. on top of all the stuff listed you will need to change the coolant lines that connect to your heads that is presently tucked under your ls1 intake. get the lines for an 01 or 02 camaro from gm as they already came with these coolant lines because they came with an ls6 manifold. i have yet to dyno but i know i will have some nice improvements.
oh and ls2>ls6 looks and functionality 78mm vs. 90mm ??? are you joking? look at som pics of the difference in size. no comparison.

I'm sure you did feel a difference going from an LS1 to an LS2, as it's about the same as going from an LS1 to an LS6, which I can attest to myself. 4500+ had a nice boost in energy.

There have been a number of articles that show the LS2 is only slightly better than the LS1 and still not as good as the LS6.
For referece:
LS1<LS2<LS6<FAST78<FAST90
I say don't bother and step up to the LS6 or FAST.

i dont know where you guys are getting your information from.

^cam only ls6. the LS2 intake made only 9-12 fwhp less than the FAST 90mm. the ls2 intake made its peak HP at lower RPM than all the rest of the intakes. and the ls2 made more hp and a little more torque than the ls1 and ls6 intakes. also you dont need the fuel rail spacer kit if you use the ls2 injectors and fuel rail but then youd have to change your injector clips to ls2 style which you can get on ebay for $70.00

I extracted the data from the article:
BTW: the cam they are using is 236/241 113 .602/.567
Other than that just 243 heads.

If you think it's worth it, and actually trust those results as factual, nobody is going to stop you. Remember the lid comparison where the magazine tested every lid? Some went 13.1 and some went 12.9.

the higher hp ls6 intake is with the 90mm snout put on it which i think is 4-500 plus your core or an addition 375 or some crap.
i dont think TPIS was trying to fudge the results because the dyno results from the ls2/ls2 TB and the Ls2/TPIS TB (same with the FAST intake)the stock setup made a few more horses than the aftermarket TB. if they were ashamed of it youd think they'd fudge it a little and try to show that there stuff made more power....but they didnt.
also if you look at where the LS2 intake makes its peak power and compair it to the ls1 or ls6 it makes 27hp more at 6400 than the ls1 and 20hp more than the ls6 at 6400. its just if you plan on revving your car to 7k you might want the ls6 but if your into it that far you might as well get an edelbrock intake.
it all depends. i got a complete ls2 intake/fuel rails/injectors ect. for free. so i dont mind thinking about it but i could probably sell it all and be close to being able to afford a FAST setup. but it only made 10fwhp more. but it also helps when later on down the road you go with big cubes, huge cam ect it will helpa lot more.
