Finding 75 HP
I'm looking to add about 75 horses to my stock 92' Coupe this summer. I've finally gotten all the exterior and interior looking how I like it so now I need a little more giddy up. Only problem is I don't know what would be some of the most reasonable possibilities. I'd prefer not to compromise my gas mileage too much. So what are some ideas and price ranges? My limit is about $3000 for all parts so I guess i'm asking more about what I could do for that kind of money since 75 HP might not be feasible. Thanks in advance.

Im sure the LTx guys can add more detail, but I'll get you started.
Ported LT1 heads, hotcam, and roller rockers will get you there and leave you with money to spare. You can probably squeeze in LT headers too from Exotic Muscle.

How many horses would that give me and what kind of price numbers am I looking at for each? Sorry if i'm nit picky, just trying to get all my research straight. After all, she's my baby. 
Also, some brand names to go for would be great.

I have spent right at that on my car.
new cam- i would suggest a more aggressive cam than the hotcam--$250
1.6 roller rockers- $200
lifters if car is over 100k- $200
LT headers if emissions isnt prob- $600
ported stock heads - $500-700
if u change ur mind on gas milleage- go to a 3.73 gear if an auto - $300
labor for all- expensive probaly at $1000 or so in labor maybe more depending on ur connections
this will get u close to 400 flywheel horsepower and u should run mid 12's
have fun

Oh yeah, it's a 6-speed with 76k on it. And I have really good connections to some quality mechanics who owe rent money so i'm alright in that department. Any advice on brand names to use? And how much would the 3.73 gear hurt me in terms of gas mileage?

while i have no experience with nitrous, i've heard too many stories before.....engine longevity too much at risk. do it the real and manly way with heads/cam package

Send Radpolo96 a message. He is in the process of adding some HP to his LT1 (heads and cam). He can give you specifics on whatever else you need plus give you some before and after dyno results in a few weeks if you can wait.

I am not really sure why head/cam power is better for the street than N20. Power is power. The only draw back to nitrous is needing to open the bottle and refilling it.
Going to a bigger cam and porting the heads, etc. also adds additional stress to your parts - increases cylinder pressure and usually increased RPM ranges. When you are talking about spraying 75-125 HP, there really isn't the concerns that once existed with nitrous. The systems have been really well designed and are very conservative, meaning rich, to drastically minimize lean conditions - so long as you don't deviate from published jetting combos.

The neat thing about this sport/hobby is that there is room for every viewpoint.

do yall think the guys in the import forums have these same dillemas? I guess the only diffrence is that they're just hoping for 200 hp not 400.......either way you look at it its 50 horse per cylinder, so maybe they are on to something..hmm ya right.
