I have a 1991 RS Camaro with a 305 and a 5 speed. I have a K&N, 3" flowmaster catback, and a chip that a friend got for me as a gift (i dont know what kind it is but it makes the car run a little better). Should i be affraid of modern v-6 cars. For instance a 2000 mustang or something along those lines. What kind of mods would make my car faster? I'm thinking about a y pipe and headers, TBI riser, hypertech chip, gears,... What is worth my time and money? thanks a lot.

American muscle all the way!

 

IMO... gears will be one of the biggest difference you will feel. It depends on how much money you are willing to spend and how mechanically inclined you are though. If I am not mistaking you should have 3.08 gears in your car right?! Try going to a posi unit and 3.42 or make the jump to 3.73. I haven't run into too many 6 cyl. mustangs that want to run so I can't give you a good guess really on that. You might want to try the theoretical board for that one. I like to think you could take him though. You should have more torque than him. My $.02.

 

Gears and posi are great. I would like to add the ultimate TBI mods.

You got to get the air into that engine as well.

Note: My wifes 98 Maxima would kick the crap out of my 91 Camaro before changing the gears, exhaust, and tbi mods. Now I can beat her but not as bad as she use to beat me.

 

dude my 90 300zx nonturbo eats up my camaro rs all day long!!!
my camaro has dynomax catback tbi chip, fuel podspacer, 3x14 open element filter with the 60.00 xtreme kn lid i also just intalled the march aluminum underdrive pulleys, its still no contest!!! my rs is a 5 spd as well.
most modern v6's are quick!!! look at the new nissan altima 240 hp and the maxima se 6spd with 255 hp they both are in the 14's stock
alot of the newer sporty cars run in the 14-15 range. look at consumer reports or road and track to see what the stock times are. if my z was stock it does like a 6.8 0-60 with i beleive a 15.4 1/4 but mine isn't stock... hehehehe but and i say this with extreme optimism. the 305 should be able to be built up to spank my z as i am sure some of them on here can.
the z i own has intake exhaust asp pulley and jwt chip thats almost 2000 in mods luckily the only one i paid for was the asp pulley. the others were done by the previous owner. headers for this car is about $600.00 the msd system for it is another 500.00 and the extrude honed intake is another 400 so as you can see that is way to expensive but it is a fun car to drive and it handles way better than my rs.
i think with the v8 its got more potential... but who knows... the fastest us nonturbo z is like a 12.5 sec car but it has a 100 shot of nos to go with it. i also have nos that i bought for the car but it never got installed. i can't use it on my tbi unless i figure out a way to make it a vacumn fpr...
but my rs is getting close though. i need to get some one who can drive to race me in my camaro with my z to see how close it is.

 

Yeah it kind of bugs me that v-6 cars out run v-8's. I had a friend who had a 1993 300ZX. Unfortunately he is a terrible driver and put it into a pole 9 days after he bought it. I guess thats what happens when you give a 6' 8" clumsy guy a car he has no business driving, he could barely drive a stick and into a pole at 70 he went. He wouldnt allow me to drive it but from shot gun the thing was quick. I wish mine was faster. I am accumulating money and hopefully i will fix the beast soon. Rock on!

 

Hey don't get down on the V-8's there is still no substitute for cubic inches. If you put the same amount of work into the V-8 as did the factory on the V-6 then there would be no contest. Our cars are put together to put out a resonably cheap sports car that many people can afford. For example look at the corvette. Look at the time and money GM puts into that V-8. Can a 300Z touch that?....NO! It really just depends on the amount of time and money put into the drivetrain. That is just my 2 cents worth though.

 

I will settle for no less than V-8 car. I dont care what kind of million horse power DOHC 24 valve v-6 they build a V-8 car is a standard in my opinion. I've had 2 V-8 cars (1969 Mustang, 1991 Camaro RS) and a 4cyl ford probe. Guess which ones i like best. I just have to do a little work and thats ok. I am willing to work for the cause. All hail fast cars. Rock on.

 

my 90 RS (L03 auto) with only a K&N open element ran just about even with my friends 2000 V6 Mustang. Now with all my mods now he has no chance.

 

That is good to know. Thanks

 

thats what i was trying to say... the older 80's v8 are easy to beat if they are stock i mean come on the rs has 170 hp... versus the stock 222 hp of the 300zx na look at the wrx its a 4 cyl with 227 hp and it is so small it runs in the 0-60 in like 5.8 so turbos do substitute for cubes it makes the car run more efficient but if you put a turbo on a v8 and compare it to a turbo 4 the v8 would win hands down because of the amount of air it moves!!!
gm has not put all that much into the 305 come on it has horrible exhaust manifolds ... my wifes 4 cyl camry runs in the 16's stock. techknowledgy is increasing and gm is behind... if they could start producing more efficient engines they would be awesome!!! i saw a 3.4 liter gm v8 that was dohc 32 valve and it had like 350 hp or something high like that... now thats great for a stock motor!!! but 170 out of a v8 that weighs in at 3200 or 3400 pounds is too weak. even with the mild mods i have it still is proboly in the 15's i need to shave almost a sec off of that to even compete with a nonturbo z.
twinturbos are even faster i see modded tt's beat camaros with 350's easy!!!
plus look at the rx7 gen 3... that is a bad car stock it has 255 hp out of 1.3 liters i remember reading on here a few months ago some one with a 305 blew one away... what a joke. the problem with the 7 is getting it to run right. they overheat too easy and with the right mods they scream!!! think about a 2600 pound car with 255 hp is always going to beat a 3400 pound car with 225 hp easy its no contest. and unfortuanitly for us amaerican car owners the import performance parts are getting cheaper.
and more broad any joe smuck can put a turbo on anycar... christ they put a turbo on the new toyota matrix with a 10.5 compresison ratio. look at that new souped up focus. not the production one but a ford racing one... it had the same times as the new corvette. so don't think just because it has more cubes its better. my wifes car gets 35 mpg and runs in the 16's we can drive over 500 miles on one tank of gas... i am lucky to get 250out of my camaro. and i didn't buy my cxamaro for quality i bought it because its soo dang cheap to fix!! and if i want a 350 i can drop in a 350 or 383 or 400 or even a 502. you can't take a 300zx and drop in a bigger motor with out haveing to do expensive machining and work. the camaro is versatile and thats why i like it most of the people i know can't beleive i bout a camaro but i am proud of it. its cheap and it gets the job done!
but you must realize even if you people don't want to own anything but a v8 other people and there are alot of them... want 4cylders and 6's because they can be made to be as fast or faster than most stock v8's so standby to be beaten by little imports with turbos and nos... the import hp numbers are all increasing every year they jump a bunch... like i said nissan is who to look out for!!! the v6 altima stock runs in the 14's so does the big maxima. and those are family cars that are heavy. hp in 4 cylinder cars right now are between 130 -200 hp v6 goes from about 150-275. and those are stock so technology does get better and if you want to beat them we need to make our big v8's more efficient high torque only gets you moving but you gotta have high hp to get it going ... soory i am rambling and i just woke up!!!

 

Unlike a lot of you, I didn't buy my Camaro because it was cheap or cheap to fix. I am 35 years old and so in high school most of the 3rd gen Camaros were new or not very old. I loved the body lines and overall look of the car. So I bought a 91 Convertible because I like convertibles and 3rd gens so I put it together. I have a 99 Trans am for going fast. I rarely race any more but I still love the feel of the horsepower on tap. I am going to build the Camaro to run with the 99 TA and be just as streetable. I just started from the opposite end than most people on the Camaro. I changed the gears/posi and the subframe connectors, lower control arms and balanced driveshaft to prepare the car for the horsepower that I am going to put in it. Instead of fixing the stuff that too much horsepower breaks on the stock system. I have built a 92 Truck that put out just over 400hp so I can do it again. Well enough of my rambling too. Just didn't have anything better to do.

 

Your 92 truck, what heads and cam are you using? Do you run the Holley 670?

 

I ran the stock heads with porting from a friend who works at one of the Nascar shops and larger valves in the heads. They still didn't flow great but didn't cost me anything. I ran the LT1 cam and a Paxton supercharger with 8-10 psi boost. LT1 cam runs really well in a blown engine BTW. I was only making 270hp at the rears with no boost while tuning stock injection system and 407 later under boost. So I cheated a little on my 400hp but with good heads and cam the same hp should be achievable. Also I ran the 454 TBI unit on mine with a bored edelbrock intake. After a couple of years on this site and some new products I would have done it a little different. It was nearly 6 years ago when I put the 92 Truck together and I don't think this site existed then or if it did I was unaware of it. Truck is gone now. I traded it in January for my 99 TA. Looking for another truck now. Would like a 454SS but don't know if budget will allow. I really have too many projects going now to take on another. Bidding on a cool 454ss in PA on ebay but it will sell for way more than I can afford to spend on another toy right now. Got 5 cars and a motorcycle. Wife has been flexible but she may snap on another one.

 

I would suggest getting rid of that piece of "S" motor you got and getting a bigger one. Find some other retard like that 300zx guy who had a built z28 but can't drive so he crashed his car and take his motor. i'd rather do that than slave over the engine you have.

 

Dude-don't let a 300zx n/a scare you into getting a brand new engine yet. Do other mods first that will transfer to a new engine or complement it, i.e. gears, tranny upgrades, suspension. With my stock intake and rockers (all my other mods were in place) still on the engine I smoked a 300zx three times in one night. Once from a light (completely left him!) and twice starting at about 30mph. I was in second gear when we went (he was still in first) and still left him. We pull up to another light and they try to get us to go out on the highway. Whatever.

 

dude how are you gonna beat a 300zx doing a 15.7 hello a stock na z does 15.5...the only way you beat him is you were a better driver!!! also he could have had a 4 seater it weighs3600 pounds vs the 2 seater at 3200

 

It's easy. The 15.7 time was before any chip tuning and horrible launches (I had just got the T-56 in-the first manual I've ever drove). The chip helped out a ton-the difference felt before and after was equivalent to changing from the open 2.73 to 3.73 posi. I can actually launch my car now too, as where I just spun through first at the track. Also, the 15.5 stock times for the 300zx were most likely achieved with a proffessional driver and ideal weather conditions. I don't know if it was a 4 seater or not, but it either way it's still a 300zx.

 

I dont know why i was not afraid of my friends 300ZX. I guess being a good driver helps a lot. It kind of bugs me when a rich kid gets a $10,000 car and piles it up. And he is getting another one. oh well you cant win a race in 2 pieces. Rock on!

 

z's are very touchy handling cars... if you do it right it handles great but i have met several people who put them into ditches and stuff!!! also never ever under any circumstance try to drive over like 40 mph in the rain!!! the traction is awefull!!! i even have problems even though i have new tires on the back... the z uses 225/50/zr16's they are yoko's and they still slide in the rain... i almost bought it coming up the on ramp doing about 20 mph my car almost did a 180... and also there are alot of people who are z nuts that do know how to drive em!!! the fastes 0-60 time in a stock nonturbo was by the car and driver guy at 6.8 sec... the tt z is 5.5 0-60, with my mods i can just barely beat a stock tt but i have seen quite a few tt's that run 13's and about 4 in the 12's but they are too big and heavy for anything better... also those have at least $10,000 worth of extra work... for 10,000 i could get a killer crate motor!!! and out run any z except for the blast racing 7 sec z... but that is an awesome car!@!!!!

 

I never got to drive my friends zx, but i went with him to check out an auto version and the thing handled great i tried to slide the thing and had a tough time. Granted i was on a test drive and wasnt perpared to pile the thing up, but it seemed like a good handling car. My friend obviously didnt think so. The guy said he just had a brake job and the brakes felt a little marginal I thought the brakes in my Camaro worked better. Well anyway.
