    500WHP cam/head setup?

    I think I may have posted something similar to this a few months back, but I'm looking for 500whp WITHOUT using any forced induction (yet..) What would you guys recomend for a good head/cam setup? I've already got the forged bottom end in, now I've got the dough to finish this project.

    Thanks a million guys!

    AFR heads and a mild cam will do.. or if you want a good cam G5X3 is neat,
    lot's of rwhp from that one alone. AFR+G5X3 > 100rwhp gain.AFR are on the pricey side, but worth it if u got $$

    why not supercharged or turbo?

    Listen, I have put over 10k into my engine. Then tranny when it broke, then rear end when it broke.
    if it had the 10 to do over again I definately would go with procharger and intercooler. I have A4 and upgraded to Redline clutches and now it is great.
    i saw the show "Horsepower TV" and they did a 98 ls1 camaro and put 541rwhp on there dyno after tuning.
    I am NOwhere close to that.

    That doesn't sound like bad idea. Maybe I'll go with Patriot heads, a decent cam, and then throw the Procharger on and give a good tune. I'm definetly not worried about my rear end. I've had this rear end at 650whp when I still had the 13b in this car. I've heard of guys going all the way up to 800hp on a 20b with this rear and no problems. The tranny is another story...

    look at my mods and future mods... the thing is a new tranny and 12 moser bolt is a must when going 450+rwhp.

    This motor is in a 93 RX7. Before I went with the LS1 I was running 650whp out of a 13b rotary into the same rear end that's in there now. I blew up my motor before that rear end will ever go out. I'm not worried about that at all. I'm running a KAAZ 1.5 LSD with chromoly axle's and like I said, I've seen these things get smacked with 800 hp no problem. Hell, I've heard of 1000 hp through these with no problem. I know I'm going to have to beef up the tranny to make it reliable. we'll see what happens. I'm shooting for 500 hp in a vehicle with a curb weight of only 2200 lbs.

    also, if you don't match the cam with the stall that u may wanna do. uh, issues later on..

    about the rearend 12 bolt is necessary if you wanna get on it like on the track,, if u got 500rwhp and still got the stock on, cross your fingers.. at least the case on LSx. I think they got a better rearend for LS6/LS2 and LS7.. but LS1 definetely.. go do some searches on this site, everybody agrees on that one, learn from the pros .. I usually would not get advice from somebody with 50 posts.. talk to people with 600-800-whatever posts but that have been here for a while. u learn as u go, so did I

    I was running the rearend I have now (IT'S NOT THE STOCK REAREND!!) on the track (at 650whp!) without issue. My brother ran an RX7 of the same year as mine with a 20B triple rotor at 800 hp with THE SAME REAR END without issue. The rear end on this car is not a problem. What I'm probably going to do is just get a nice cam/head combo, and swap in another cam when I put the s/c in. That's not going to be for a while anyway.

    lol no one is helping him out......
    All i can try and say is try and find a set of heads that really match up those texas-speedcams....

    I have a torquer v2 making 400 rwtorque.......only 364rwhp though......but torque is what counts.

    That is cam only....>I can only imagine if I had a nice set of heads to match

    TSP Rumbler, LT's, TSP Tqr2, PRC 921 Springs, Comp Lifters, Chromoly 7.4" Pushrods, Titanium Retainers/Seats/Seals, ARP head bolts, BMR full Rear suspension

    In a drag race horsepower is what counts.

    It does.....but I'd rather have that torque than the horsepower.
    Horsepower sells cars but Torque wins races.

    Yes for a street car you'll want the torque but in a drag race horsepower is what you want especially if we are talking 470-500 RWHP (NA) most of the time the motor never see's less than around 6500 rpm depending on the setup. If you want a car that really puts down 500+ RWHP your going to need ported FAST 90/90 set up, ALL the bolt ons and a good exhaust i.e LT's, ORY and TD's or a good catback like borla. Contact Dave at CARTEK he'll set you up w/ a package to get that number but most importantly it will run the time to back the numbers up not like some "dyno queens" I've seen.

    You make 364hp/400tq?
    All things being equal a car that makes 400hp/364tq will beat you in a race.
    In races hp beats tq.

    Torque feels fast, Horsepower is fast.

    What forged components did you install? Stock cubes? Automatic? 500rwhp heads/cam packages are rare and often cost more than a mild stroker making the same power. You'll also need a ported 90/90 to feed it...
