hey im fernando
i got a 91 rs 305tbi
i was wondering if could just put a nice breather on it in place of the stock breather with the snorkle

 

By breather do you mean air cleaner? You can, if you don't mind sucking in air heated by the engine.

 

yea just a like a nice clean chrome 1
would it effect the way my car runs at all?

 

thats one of the first mods people do with tbi you might see a little crisper throttle response

 

I believe this is what your looking for...

Scroll down till you see "Aftermarket Open Element".

 

thanks guys im sure ill be on here asking all sorts of questions alll the time hahaha
i bought it for 900 bucks not a bad buy at all had to run the fan to the ignition and the ac/heat doesnt work and had a couple of little dings but got them out next step is wet sanding priming it black tint and leaving it like that for awhile while i do motor work i have an edleborck performer intake and flow master exhaust right now next im thinking 350heads new injectors and a cam any opinions???

 

350 heads would be a mistake.

 

I just did this 2 weeks ago. It did give me a little crisper throttle response and it definitely gave me better top end. The 4000rpm and up zone where it wasn't getting enough air before revs a lot freer and more quickly now, on up to 5500.

I did feel like I lost a tiny bit of low end torque, just off idle, but it comes back quick. My guess is that although the higher rpms were starved for air with the stock air cleaner, the 1000-2500 zone had adequate coolairflow, which is now replaced with hot air.

Overall though I am happy with it. the car is faster overall and you can get the low end back. If you do any more mods you will need that extra airflow anyway, hot or not.

I used the Jegs house brand 14' chrome open element. It is 34.99 and comes with a K&N stlyle filter so I have no clue why some people are paying $70 bucks for other brands. It also opened my underhood space up a little which is nice.

 

yea u dont need to spend that much ahhaha
i gotta still do a full tune up u can tell while ur driving it its so bad haha
but thanks for the responses guys

y would 350 heads b bad? a 305 block is basicly the same as a 350 just less of a bore

 

im not 100% sure on this, but i believe that 350 heads will lower your compression ratio (stock is 9.5:1), which is about as low as i would want to go on any motor.

 

well im not looking for like a huge amount of horsepower but is the 300 350 horsepower area asking too much on these motors or nah

 

you'll need to do a little more then heads and a cam you need to get into tuning if you dont then i would advise you to not do more then full exhaust and ultimate tbi mods imo
----------

ya i beleve the 305 heads are 58cc and the 350 heads depending on what ones they are are 64cc

 

i have a full exhaust minus headers but gettin em with in the next 2 weeks
just 1 bone to pick with gm hahaha why would they make a v8 that only puts out 170 hrspower?

and also the edlebrock performer intake manifold***
