Looking for some advice about modding my l98

Hi everyone great to finally have something to ask about on the forum, so let me get right into it

i read a lot about the l98 and know what i want but i am just having an incredibly hard time finding how to go about doing it because of all the conflicting information people are saying, so i hope by asking and letting you guys know what i want to do with the l98 i can find my solution and get my l98 running.

I basically want to keep the l98 good at what it does which is low to mid range rpm power, this is a weekend driver and the car is most fun to drive at those rpm ranges,

the mods i want to do is to basically amplify what the l98 is good at, by doing intake, heads, and cam (yeah and also some sort of computer tuning or something, not very good at this part )

i have read about the first intake, eddlebrock, superram, mini ram, etc,, which one should i go with for what i want, i wanna figure out the intake so i can decide on the heads and cam i go with,

Or does anyone have a proven combo that works great for a daily driver/weekend cruiser?

Oh yeah one more thing i wanna keep it emission legal

thanks in advance!

Some good low budget aftermarket heads, ZZ4 cam, bigger runners, 52mm TB, Dyno Don headers with dual cats, Magnaflow 3in cat-back. This should get you around 320-340rwhp with a tune. For starters, get the exhaust done first.

Hi guys so I have completed my profile, I have three third gens and atm I am working on fixing up the 1989 GTA, the car had a bad fuel pump so I decided to change that and start to modify the engine for some performance gains while it sit in the garage.
