need some ideas how to beef my 92 rs 305tbi up any ideas helpful. THANKS!
 

i was just wondering how to beef my 305tbi up.
tuning or new performence parts to add power.

All i have done to the 92 RS is a edelbrock open air cleaner
Jet stage 1 chip,b&m mega shifter, flowmaster cat back exhaust. no headers.2 1/2 inch fiberglass cowl ind. hood. Any hints ideas or proven ways to beef it up will be helpful.


THANKS, EDRcamaro

what are you goals for the car ?

get headers, there is alot to be picked up there.

then i suggest getting into tuning. then suspension work. after that if you want more, you are probably better off going 350. or you are looking at a heads/cam swap.

o.k.
 

thats cool. im been thinking of headers for a while.
about switching heads and the cam do u have any suggestions.
what kind of tuning can be done. on a regular day without spending any money. and 1 last thing witch is better the stock closed air cleaner or the open. thanks i appreciete the help. im only 19 and just getting into carz. iwant to brake the 14s. until i get used to it then i waz thinking on a 383 MPFIif that can be done or just a supercharged 350 ram jet. by the i got the completly done for strip and show i hope it brakes 10s

with your cowl hood, assuming it is functional , i think you are better off with the open cleaner.

tuning, i am talking abotu comptuer tuning, it will cost you about $200 to get the equipment to get started, assuming you have a lap-top, if not figure another $100 to get a used one.

cam/head/intake combo's very alot, depends on budget, goals, driveablity wanted, computer tuning skills, ect.

typicly if you are looking at a heads/cam swap, you can usualy step up to a 350 crate motor for not much more money.

thanks i'll look into the computer tuning. all thats left after the motor is done i waz thinking of a373 posi rear end

i personaly dont' like 3.73's in our cars, unless you do a cam swap, and can build upper RPM power. but there are people who disagree with me on that.

thanks
 

wellim just getting into this stuff and i can use all the help i can get. would there be a certain rear gear that would do the job?

Yup, I DISAGREE! I have 3.73's and I think they were one of the best things I did. I really enjoyed the new get up and go compared to 2.73's. It really didnt effect my highway speed too bad. I almost put 4.11's but I think that would have been a bad move now. I guess I am just giving it a 9.5 out of 10 on the fun factor!

for you i would suggest 3.42's or 3.32's

(BTW -- side note -- is it just me or has there been ALOT of rear gear discusion today?)

thanks well i'll look into both of your ideas DEW. then i'll look at the 3:73. thanks a lot guyz.

Yeah it seems like there's a lot of discussion on rear gear ratios. I tend to agree with Dewey on this, its only logical to put a gear in that will put you in a powerband your cam and heads can actually support. I think 3.73's in a stock LO3 are way overkill. I think many people that put in the 3.73's and say it was a big gain don't have solid timeslips to say it was a gain, it just feels faster which a swap from 2.73's to 3.73's will obviously do but that doesn't mean that 3.73 is the optimal gear to use. I chose 3.42's because I have a 5-speed and am stepping up to a 350 very soon I figure they should use my intended powerband well.

alright
 

i'll look in getting the 3:42. u wouldn't know much the set up cost to install that gear ratio and a posi.
THANKS!

you can check out the ultimate TBI mods in the tech articles section and bump your timing...i hear 6* works for most people but you can test for yourself

I picked up 3.42 gears on a 2001 Camaro SS posi carrier off ebay for 170 shipped. I think I got them installed for about 150 but I had a connection with that so I'm not sure.

Do you have an auto or manual? Remember that I have a manual and am doing this because I'm planning an engine swap. How far do you plan to take this 305, heads/cam swap? Or are you going to step up to a 350 eventually? With gears I would plan for the future.

i have a auto. my car before the jet stage 1 chip ran 16.03 at US 41. i'm looking at try to brake low 15s or high 14s before i decide to step up to a 350. i waz thinking a little bigger cam. what do u think. if i step up to a 350 it won't be for a while. 1 year maybe.
