Beat by a Honda

A few days ago a me and a friend raced. He has a '94 Honda Civic Hatchback:Cold air intake(fenderwell), Header, Some kinda ***** catback and they installed an Integra GSR motor with V-tech. I have a '91 Camaro RS Auto, Stock. I just got it so I havent quite perfected take offs. We pulled up to the light and when it turned green, we took off. We were neck and neck for a sec. but then he left my *** pretty bad. I want something that can beat the **** outa him. I was thinking lose the smog pump, go to a carb, headers without all the air ****, and a 3in catback. Anyone have any other suggestions on mods for a win?

Thanks

Spray it That'll get you the best results for the money. Just make sure you keep track of how full your bottle is. Cuz you just know, one day you'll get challenged and the bottle will be empty.

Other than that, loose some weight (from the car! 100lbs=1 tenth), change the gears, swap a bigger cam in, port&polish the heads/intake, etc. A torque converter will tear him up at the line (if you don't smoke the tires) but it won't help as much on the top end.

Ok that car sounds very similar to somone i know around here who has a honda, and his runs a 15 flat. Its gonna take some $$ to make a TBI/auto car do that, as i am unfortunately painfully aware as i'm on a very tight budget. Theres a couple guys who can run that fast with a TBI and a few who are even faster. I'd say to start with get a decent cat back of your choice, non-air headers and no cat/smog pump, open element, 3.73 rearend with a good posi, and that'll get you much closer. But to beat him its gonna take more fuel, a chip (possibly custom), and maybe 1.6 rockers and a cam (which requires MORE chips tuning). The swirl port heads sure aren't helping either, but thats a very expensive upgrade. Basically what i'm saying is its gonna take lots of work to make an RS that fast. But i'm not talkin sh-- to you, my car has the same engine and its nowhere near Vtec spankin fast yet.

he's right, it's gonna cost quite a bit to get an L03 to go anywhere..for the money i'd say get yourself a decent 350 built, slap a carb on there, 3.42's or 3.73's...and you'll be fine, we all suffer from the sh**ty 305, ditch it

Actually, if you do this and put in a nice but not ridiculous cam, you should have him as long as you get a good launch. Go get'em!

I would like to make a few things very clear. The Lo3 has a very nice bottom end but the heads are ****. If you ever take a look down the intake port of a stock head you'll notice that you can only see HALF of the port and the valve. This really hurts performance because it's like giving your engine this HUGE header exhaust system and then sticking on a 2" muffler.
If I still had my 305 I know I would have to do something about the heads. I would either save for the edelbrock or worlds products BUT the vortec heads after all the machine work might be an even better bang for the buck. Once you scrap the "velocity" port heads you've got a LOT more potential.
If you're going to do a cam swap and an intake, why not just go a little deeper and do the heads?
As for getting a stock 305 into the 14's, this would be my plan with cost in mind.
Intake manifold, home made ram air or open element, better rear diff with low (high number) gears, a nice bump stick like an Lt1, headers to a 2.5" or 3" exhaust depending on your bump stick, then loose some weight (about 200 lbs). To get the hole shot I would think about better LCA and relocation brackets. Those mods had better get you into the 14's but if you did the heads you'd be punching for 13's. Oh yeah, and after all that work you'll definatly want to get a custom eprom burned or bump up the fuel pressure.

4th gen or 350 time for you. My 350 is bone stock save for the headers, and I run low 14's with a 305 throttle body. Our cars weigh about the same, and If you have an auto, thats one thing going for you.(good launches) I would look for a 350 to build up, and just put some flat top pistons in it, and get yourself some good Cast Iron heads, and a good intake, and slap your throttle body on that. I would not trade a my TBI for a carb if it gave me 50 HP! The drivability is just not there with a carb. Trust me. I have done both. I still have the option to put performance parts on my motor, but choose not to. I am damn proud to have a classic daily driver that is injected, and gets 20 mpg with 3.73's and a 4 speed.

Its probably going to get moved pretty soon to Racing board but here it goes.

I have raced my friends 95 Integra GSR 5spd and I have handed his *** every time. Now I know that his car is heavier plus he has sounds but he also has headers, no cat, cat back and intake.
Make sure you race him from a stop position cause it is hard to keep up with them once that Vtec motor gets going.
As for mods, exhaust and gears youll need nothing else.

No offense but rice throws bottles on anything. Thats why they are fast cause thats all they can do is throw a bottle on. So if u look at it, thats pretty pitful. A car running a 15 flat or 14's thats on the bottle.

Don't let the bottle scare u. Anyone can throw on a bottle and push a button. It takes skill to make a car run fast on motor.

with or without the bottle if you lose you lose..and actually the guy runs a low 13 in a honda civic.. all motor he runs a high 14... so w or without the bottle if you lose you lose.. i think of the bottle of a mod and you cant just throw the bottle on a car unless you dont care for your engine...
with gears posi exhaust and maybe a cam you'l be something to be recon with.. and you'll spend half as much for every mod!! chevy runs the mother!!

I disagree. U can throw a bottle on anything really, as long as the bottom end is half way decent or ok. I have seen people throw bottles on GEO's for godsakes. So no, I don't look at throwing on a 75 shot of NOS and hitting the button all the time a good mod. NOS is suppose to be "insurance" when it comes to street racing.
