hey guys, i finaly find a decent thirdgen camaro around my area, that i can take a look at, its a 90 rs with the 305, however it has 134kish miles on the clock...


me being new to the v8 thridgen world.. what should i look for? and anybody know what year's 305 got the tpi in the rs's? (if at all)

 

I thought all RS's had TBI, but I really don't care as I am IROC biased

Here's another useful tidbit for you...

tomorrow: Definition and Much More From Answers.com

 

RS's never got the TPI. you may be thinking about the Irocs getting the TBI

 

Every rs besides the b4c came with tbi. If you are looking for a performer, you should probably look for a 90+z. They're tpi and speed density. Good for tuning.

 

how much they asking?

and where is it at?

 

Like they said, every RS was equipped with either a V6 or an L03, except the B4C which had an L98 of course.

If it's in great condition for it's age, 2 grand tops. I personally wouldn't go over 1500.

 

I'm sure you'll notice a difference going from the current motor you have to a V8, however, I would reccomend TPI. I went from an 84 HO 305 to an 88 IROC w/ a TPI 5.7. A noticable difference. Don't just give in to the first V8 you come across unless you have goals of future motor swaps, etc anyways. Although I'm sure that some might swear by there 305, everyone I've ever talked to said a 305 is best used as a boat anchor. 350's are easier/cheaper to build more hp than 305's. Do some more reseach before making a purchase. I know that after my 84 was totalled I was determined to get a 5.7 w/ TPI. The 90+ are better also. I just couldn't pas up this 88 of mine.

I kinda disagree. If you plan on building a high HP car then SD is the way to go, but if its gonna be more of a daily driver I say go MAF. with the SD system you can hardy mod it before you NEED to tune it. MAF on the other had has the ability to adapt, because its actually reading the amount of air going into the motor and looking at other sensors. SD looks at a number of sensors to find the right amount of fuel to give the motor(actually a little more complicated), but has no way to adapt so if anything is done to make the motor pump more air in/out theres no way for the computer to compensate for the mods with out tuning.

in short. MAF responds well to change. SD set in its ways

 

Me and the rest of the sane people would only use SD for force-fed applications.

Otherwise MAF is far superior, as stated earlier the motor runs better responding to the air / fuel ratio then guessing based on engine vacuum.

Why do you think they went back to MAF? Hmmmm

 

not gonna tell ya where its at until i look at it :P, and they are asking 1500 for the car, im gonna take out 1k and if the car checks out, and its decent looking, i might grab it, though i might just walk away and say, ill call you in a week btw this is the car im looking at

http://fresno.craigslist.org/car/147077058.html, yea i know, i can find better, but atm all thats listed in my area are 4th gen's w/v6 or thirdgens with v6

 

yeah thats an alright deal

i say if you get a TBI 305, 305s arent all that great but hey you get what you can afford.

do the TPI swap, you'll be looking at an additional 40HP alone on all stock parts. and it all bolts right up so if you get some aftermarket equipment, you could pull some nice power out of it. and BEWARE 305s blow header gaskets. so id definatly put some copper ones on there.

and yeah i already have my thirdgen and its my baby. so you dont have any competetion there.

if you want a hand taking a look at it let me know.

 

why would a 305 blow header gaskets faster than any other SBC?

 

not sure but ive never heard people have such a nightmare with them as i have with 305s and ive had a crazy nightmare.

maybe its just me.

 

I love my dang TBI. It's reliable and gets decent mileage to a tank of gas on the road. 180 HP and 260 ftlbs of torque is all I really need too. I secretly lust for 300RWHP but what does that get me in reality? More speeding tickets and more money at the pump.

Moving from the V6 to the 305 TBI will certianly be nice for you but it won't get you the respect of other muscle cars but it will get you into the V8 club.

 

My 89 RS (305TBI) has 207,xxx on it and it runs fine (except for smoke on start up - gotta replace valve stem seals some day). It has adequate power for a daily driver. If I wanna go fast I drive the 2002 Z28 parked next to it.

 

i've got about 140 on mine. and i don't have any problems with it. it's a 91 rs tbi. but like cadillac said, bigger costs more in the end. and especially with cali gas prices.. sheesh.. i straight piped my exhaust, and i definately feel the difference. kinda makes it hard not to gun it just cause. if you're looking for a project car, i'd say go for it. the body looks a little rough, but nothing a paint job wouldn't handle.

 

didnt buy it.... The car looked great for about 5 seconds.. until i saw the drivers side front fender... it looked like someone took a hamer to the top of the fender... pluss the thing didnt have anything behind the cat...

 

When they switched back to maf they made the computer faster and made it as tunable as the speed density. There's info on here that supports this but i can't seem to find it. Early maf is not superior to speed density. The lt1 and ls1 maf is far superior than either.



yeah and i agree that if you don't plan on building a high hp

 

you dont want a tbi anyways, wait until you find a tpi

 

i love the waiting game...

 

TPI and TBI suck royally.

Be a man.

Get a carb.

 

carb is old technology... FI is where it is at.

 

 

I'll sell you mine. jk. If you ever need anybody to LOOK it over, just call. The guy I bought the 90 TA donor car said it was a 350 but I looked at the VIN, 305. I didn't care though. 305's get decent gas mileage and power.

Last time I drove a car with good power was my 65 mustang(15 yrs ago). Since then I've only driven hoopties and a mini-van. So a bone stock 90+ TPI feels pretty good when you step on it.
