Dual Supercharger
OTTP sells their Stage 3 kit which includes the TVS supercharger and a few other necessities for about 2500 bucks. BUT honestly...you can find them cheaper (used) if you just look around. Im not too sure but id say you could find a gently used TVS kit for well under 2 grand.

And good idea on just starting simple. See how you like that power level and if you decide that you want more then hey...majority of those parts will be used again!
It wouldnt hurt to upgrade your exhaust...but honestly i would just maybe leave the stock piping and do a muffler delete or swap an aftermarket muffler on.

Glad i can help a little! Yea there is plenty to learn. Ive been lurking on here since 08 and i still learn stuff every day.
There is TONS of info regarding modding an LSJ...just gotta look around for it. Google is your friend too. Dont use the Search function on here

Ya... I noticed the search on here kinda sucks. I search for something and all I get is "official Texas thread" "official Florida LNF thread" ect.... I really have to dig for stuff and I can't find an answer half of my searches.

Back pressure on a SC setup is a good thing to a point, but the LSJ DP is too restrictive and the ZZP unit fixes that right up:
ZZPerformance - 3 inch Stainless Cobalt/Ion Downpipe #ZZ-E3DP
ZZPerformance - 3 inch Stainless Cobalt/Ion Downpipe #ZZ-E3DP
You do not want to use an overly sized exhaust setup on a blower car. A 2.5" exhaust is the best blend between flow and exhaust gas velocity. U do not need a 3" exhaust on a SS/SC until you are north of 300whp.
did someone say TVS? 
but for real there is alot of good info on this forum that can easily steer you in the right direction like these guys have already. Just pay attention and learn as much as you can and dont be afraid to ask questions

meth is a catch 22............. yes it is used to keep the lsj cool...... however it will remove the coating off the rotors in the supercharger.... best bet is to go tvs.... however you can do a zzp stg3 setup with meth and still achieve 300..... the biggest thing with the lsj is to keep it cool.... option b, dual endpass plate, phenolic spacer, and 2nd heat exchanger..... 2.8/2.7 pulley, bigger injectors, step colder plugs are a must...... the down pipe is a must.... in light of recent activities a really good tune will be hard to come by depending on your location..... remember when surpassing 260hp you run a greater risk of using up the clutch.... so you will need one soon after, depending on driving style..... dont forget you will need a wideband or scan guage.... they are not that cheap but you must have them.....
BOTTOM LINE............ go tvs....... its a better place to start....

plenty have ran meth w/o it wearing the coating off on the rotors including myself, also the stock clutch can hold quite a bit. I had stock clutch on a TVS,2.6,1000's,full e85,meth and basics like exhaust intake
Yeah u totally dont need a ky stg 2 clutch for a tvs build hehe
like i said with the clutch its all in driving style..... the coating thing is all in how much meth is run through it and strength of mixture.... also if the car is daily drivin, does he want to continuously fill up the meth? even with a setup that only uses meth at wot it is still a extra expense.... i just think his goals are achievable without it.... however i was looking in the first post and he wanted airbags.... i feel he could save money with a good coilover setup to get similar results.... in reality he can have a very strong car with his budget but he would need to plan it..... my question is i realize the downpipe is a must but is the catback? or header.... ive heard that the factory set up is good til about 350/400?

The manifold flows well for what it is, but there are better options.
I myself run a ported GMPP manifold.
There are small gains to be had with the catback due to the small inlet dia of the resonator, and slightly restrictive stock muffer.
The stock downpipe has a high flow cat, but has a small inlet, and outlet.
i knew about the resonator..... the muffler is a given, but still not that bad.... but i never knew of the head.... however i have always known that port and polishing a head will always be a good thing.... what i guess im asking is how much hp will you gain with a catback? 5? 10? its alot of money for small gains if you ask me.... the money could be wisely spent in other areas.....

When you mod the exhaust as whole, each part will benefit from the next.
If you only mod the manifold, then the downpipe is the next restriction, and so on....
A catback on the LSJ will give you gains around 5-10 whp.
If you're going for power every lil bit helps.
U can always find a used catback on here if you don't want to spend the money on a brand new one.
i ask coz i am only running a catless dp and really producing solid hp for the mods i have.... not to mention i have a good sounding car without a catback.... now i realize that every lil bit helps..... ops goals was 300 ish.... with a good budget.... the problem with good budgets is that they are easily spent lol..... so in best interest for op, i wanted to raise some questions for him to answer for himself..... with the help of you and carstedt i feel we have done this.... now its up to him to figure out what he wants to do....

This winter im installing valve springs and increasing my rev limit.
