Re: Cheapest way to make fast. 305
yup. first thing you gotta decide is how fast you want it to be. vortec heads, an lt1 cam, performer rpm intake with tbi adapter, and some EBL flash tuning, plus headers and full exhaust will get ya pretty fast. thier are a ton of threads on this. take a look see by doing a

Re: Cheapest way to make fast. 305
A good use of your money is to get a full 3" exhaust with headers and gears for now, this way if you upgrade the engine later on you will already have those upgrades out of the way, and for now it will help your performance a bit.

What's with everyone and speed these days? lol
I'd rather have my slow but torque-y GTA have everything else redone before I focus on speed.

Re: Cheapest way to make fast. 305
my brother had a had 92 5.0 tbi auto rs back in 06 07... he did headers full exhaust cam(218 duration range) carb upgrade and was upset of the performance... my stock l98 with catback could still blow the doors off him.... so if your going for speed then id say its not worth it..... id swap to a 350 at least... besides no one will know the difference from 305 to 350 unless you tell them.....

Re: Cheapest way to make fast. 305
id go with cruisin 1980s answer
ditch the crappy stuck exhaust system headers back with something you could put onto a 350 if you choose to do the swap later
no real downside or risk + easier to get done than internal engine work, plus 305s can sound pretty awesome with the right system

Re: Cheapest way to make fast. 305
If its still stock than a 1990 Rs.5.0 auto = 2.73 open differential
manual = 3.08 open differential
Its not real cheap but as said earlier a up grade to a Eaton Posi./LSD with at least 3.42 gear ratio. would wake the car up along with a timing advance to about 6*. That with a open air element or cold air intake and full exhaust would all help.

yup even the 2.73 to 3.08 made HUGE gains for me. I gained 1/2 second in 1/4 mile just from that

In the short run nitrous would probably be the cheapest route.

Re: Cheapest way to make fast. 305
The first thing you want to do is undo all that GM did to cut down the performance of the TBI engine, starting with the exhaust and intake.
It never ceases to amaze me that GM decided to use parts that choked off their TBI and LG4 motors so much that it would make buyers have to look at TPI and L69 engine choices for more power.
TBI engines have some of the the most restrictive exhaust manifolds, y-pipes, and cat backs ever put on a third gen. Just putting shorty headers with 3" y-pipe, 3" cat, and a 3" cat back are worth over 30hp with no other real changes. You can pick up another 10hp if you slap on an L69 dual snorkel intake and K&N filter. That is 40hp or so without ripping into the motor. You can also get underdrive pulleys, change your rear gears (and probably get a posi) and some other small bolt ons. There is no reason to doubt that a TBI in good running order with the exhaust I mentioned, intake, pulleys, and gears combined with good traction can't run at least in the high 14's.

Re: Cheapest way to make fast. 305
Wasn't there JUST another guy, like less than 2 weeks ago, wanting cheap to nearly free power out of his 305? Fork over some cash or stay slow. 350 swap will be your best option if you don't mind spending more than 5 dollars.
It's not even about being young. Some people are just cheap. Since November I've put around another $5,000 into the Slowstang. SCT Livewire, T56 swap, the Vortech. Then just stupid things like the BBK mid pipe, oil changes (Since I wanted to flush the rear diff, trans, and engine all at once) and new tires really add up.
Now I have to blow another $500 on a boost gauge, wideband an A/F ratio gauge, gauge pillar, $269 on a fuel pump, already spent another $100 on 6 more quarts of engine oil for when the pan will have to be tapped for the Vortech oil feed lines, and some decent spark plugs. Making a car fast gets expensive for sure, so it cracks me up to see threads like this.

Re: Cheapest way to make fast. 305
a random punny JY chevy 350 isn't enough either.
-------------------
As the very next thing these jokers will tell you OP is you now need a stroker kit for that 350 to be fast.
until you race a guy with a BB
Buy a BB and then get trounched by a guy with an all billet BB.
It all ends up the same, 2000+ HP and 80K into a engine you can't drive more then a few blocks as its only designed to go a 1/4mile at a time.
If your gonna start digging a money pit, think ahead some.
what makes even well built BB guys nervous, even when they pull up in all stock granny trim next to them???
A Turbo V6 Buick, easy 9s, 7 with work and still street friendly and out turn anything with a big engine in its nose. [the new billet race block they got should take em into - numbers ]
decide now where you want the car to go, do you just wanna go straight or do it all? As going up in size engine wise is a never ending battle, what ever you got, a bunch of jokers will stand around and tell you why its not fast and what you need to buy instead.
Ok not thiking that far ahead and just want to pass jerk offs easier, don't care about laws to much, go spend $400 on a NOS kit and keep upping the HP till your happy starting at 75. Not gonna hurt anything of value if it tosses a rod.

Re: Cheapest way to make fast. 305
No kidding. Its great to go fast in a straight line, but you also have to be able to stop & take turns relatively well. Engine mods are at the very bottom of the list of things I'm going to work on on my car. My list order goes Chassis, Suspension, Brakes/Wheels/Tires, Rear Axle, Transmission, Seats, then Engine. Last thing I'd want to have is a ton of money tied up in the engine and a thrashed to death car because of it.

Re: Cheapest way to make fast. 305
I haven't gotten a "true" 1/4 mile run out of it as of yet and I know its not a dead accurate measurement but from where we've marked out our 1/4 and from the people I've beaten I easily have a 13.7 to 13.5 car as it sits. I will take it to the track as soon as I can but the nearest one to me is over 100 miles away.

Re: Cheapest way to make fast. 305
Cheap? Underdrive pulleys, electric supercharger, stickers, HUGE wing(don't skimp out on this one), lots of gauges, and a rattle can paint job. All of this should get you a 7 second 305 easy! In all seriousness though, speed isn't cheap.

fyi, lots of 93-02 camaros came with 3.42s and are much stronger AND an upgrade to discs if you have drums for about the same price at a junkyard It is also a bolt in swap.

Re: Cheapest way to make fast. 305
i have the simplest answer for this. a 305 simply cannot make good amounts of power or be "fast" you can do alot to make the drive and feel of one much more enjoyable but the only way a 305 can be fast is if you use these step by step directions
1) remove engine
2) replace engine with something with more displacement and power
3) drag 305 behind newly acquired fast car
Vuala fast 305
sorry thats a ******* response but 305s are a waste of time, if you want more then save up and pay for it otherwise enjoy what you have

Itd be cheaper to sell your car BEFORE you ruin it, and get a v-tec civic and adding 4 inch muffler too the list.

Re: Cheapest way to make fast. 305
If your going for rear end swap just do 3rd gen. Same width, and can get same gears. And discs dont make you go faster. Yes stop faster, but i doubt that is what the original poster is looking for.

Re: Cheapest way to make fast. 305
The 4th gen rear makes it easier to put bigger rubber on the back, so I don't really see the advantage to the shorter axle, unless the OP has a mini tub.
