i have an 84 camaro 2.8 and i was wondering just about how much hp can you get out of this engine?and what would be some good low price mods to do to it?

 

um like -20hp

 

Thats carbed correct???

Cam
Air intake
Exhaust
Coil
Wires
Plugs
Tuneup
Cap/rotor
Headers (will be expensive)
Newer heads
Timing chain
Roller Rockers

 

I am not an expert, but if you did everything you could possibly mod on a 2.8l Naturally aspirated, you might be able to get 170 bhp max, even that is a bit optimistic.

It really is a shame that our engines could not have been fitted to have Duel overhead cams, 4 valves per cylinder, and variable valve timeing, like found on FWD cars only.

 

TSK TSK

if your lucky, a 3.4 can get 210/220.

I'm not gonna blow smoke anymore. I am telling the flat truth, V6s' are simply NOT worth the time. And I am sick of you moderators banning me, give it up. I am not coming to the "V6" boards anymore anyway. There are better things to deal with, like getting something that has more then 180 foot lbs a TRQ to the pavement, without spending serveral thousand dollars.

 

You must have cared or not have had "better things to deal with" to write that.

I am about to build a 3.4, spending 3k on the cost of the motor, mods and a new suspension. I will run AT LEAST a 14 and have AT LEAST 220rwhp

VERY high flow heads, intake and exhaust, 1.8 valves, cam to match (non emmisions), VERY light car, all the weight reduction you can do and no power options, custom tuning, adjustable LCA's aluminum ram air/CAI custom made by me, I allready run a 16.6 thats with street tires, wires, plugs, cap rotor, gutted air boxes and cat converter, coil, and weight reduction.
I know PLENTY of guys with just 3.4 intake mods and exhaust that run a 1.8 on streets. YOu can make a v-6 quick for cheap if you know what you are doing, you seem to be a v-8 owner who I am sure is slow, oh by they way, go to firebirdv6.com and talk to 12secondv6 and ask him how much money he invested
Rant mode off

 

A company made a 4 or 500 horse (crank) 2.8 not to long ago, supercharged/ NOS, and a TON of tuning.

 

not really cheap, but get one of those Fageol superchargers for it. get one of those 4" of so cowl induction hoods, so when people say pop the hood & expect tosee just stock setup, they'll be like :hail:

 

what exactly is a fageol supercharger, how much do they cost (to purchase and have installed) and do they make one for a 3.1

oh yea and with that supercharger how much power would i be able to expect

 

Sorry, But I own 1 of each. And sorry to say, the V6 drags a$$.

And I have heard of that "12's" V6, And NOS does not count, any fool can load 4 NOS bottles and go at it, but how long do you think that motors gonna last? And refill charges would get old QUICK.

I read that some company is going to "supposedly" try to make and sell a turbo kit for the V6, Yeah they are gonna find out that "kids" will not pay 2K for 30 HP.

Sorry forgot, the engine I am swapping in may be 100Lbs heavier, but it also adds nearly 200HP and well over 200 Ft lbs TRQ in a very mild form. Cost of the swap...

175 engine.
400 rebuild kit
200 machine shop fees.
200 headers.
130 radiator.
100 SFC(required for the engine going in)
100 POSI unit
300 +/- for intake carb

1600 roughly?
Cost of a 3.4 thats less then half the engine.

 

Keep in mind James has a 4th gen with a 3.8 running a healty dose of spray. He had his motor built for it, broke plenty of parts along the way. It is alot easier and cheaper to get parts for the 3.8 thanks to both the GN guys, and the L67 (3800 SC) guys. The 60 degree motors really don't have alot going for them compared to the Buick 3.8. If you could swap a 3.8 into a 3rd Gen (probably can't be that hard since Pontiac did it with the TTA) that would give you a solid building block.

I'm not looking to flame anyone, and its definitely good to try something different. But when you consider it would take a few thousand dollars worth of work to get a 60 degree into even the 14s, it might be wiser just to invest that money into a used LT1 for 6 grand, and throw a 150 shot on it for 500 bucks, run 12s and be done with it.

 

Actually, the 3.8 will not direct swap, you have to use different heads.

but the SBC/BBC is alot more worth while then trying to get any real power outta the 60*, trust me people, I was once one of the biggest "PRO 60* People" on the V6 forum. I also wasted ALOT of money tring. I simply realized the truth of the matter. IT'S POINTLESS.

 

From a speed and high performance standpoint, it is pointless and a waste of money to build a 60 degree engine. I am keeping my V6 because it is a part of the character that is my first car. I use my car for driving around town and going back and forth between home and college. I rarely drive over 80mph, so I don't care much about speed from this car. I just want make my car a little quicker, its not like I am trying to make it a fast car so I can take on 12 second Novas or something.


I would like to have a fast car, but a thirdgen would definately not be my starting point. Might as well start out with something that is powerfull in stock form, like a Vette.

 

i have all the mods done to my 2.8 mpfi in my sig. its a real strong car. hangs with v8 and even beats them sometimes. i put the specs of the motor on desk top dyno and it made 174hp at 5500rpm and 191 ft tq at 4000rpm. i feel thats pretty acurate. im really happy with the car.

 

If for some reason, I had to remove my 3.1L motor out of
my Camaro, it would DEFINITELY not go back in!

I would AT LEAST be installing a small block V8 motor,
like the Ram Jet 350 with a new "tweaked out" 700r4
trans with it! I hate carbs, so fuel injected it is! This would
work well with my already equipped MPI in the car. The
fuel lines and in-tank fuel pump will hold up no problem
with a fuel injected V8 motor. If I need a high performance
fuel pump, no problem.

It's only worth throwing in "bolt on" stuff to a 60* V-6,
like exhaust, tune up parts, computer chips, air intakes,
stuff like that. All this together works well, but only to
limit.

I don't see the point in taking out the motor and tearing
it down to rebuild it with performance parts. It's better
and just as expensive to buy a V8 crate motor!

$ 4,600 for a ram jet 350, 350 hp/400 ft. lbs.
$ 6,000 for an LS-1 complete! 320hp/ 340 ft. lbs.
add about another $1500 for motor mounts, new
performance radiator, some custom fuel lines, accelerater
cable, serpentine belt system, A/C compressor, torque
convertor, etc.
$1000-$2000 for a "tweaked out" V8 700r4 to hold up about 400hp or get one already done like a TCI trans. from Jegs.com.

This is what I would do to my car, if I had the time and the
money, or if for some reason, my engine blows up!

I don't need to do the suspension, rear end, or brakes,
cause it will already have this done well before the motor
and trans.! I will have about $3,000 into the chassis even
before the motor/trans. swap.

This way, the car will hold up no problem.

 

Bye the way, with the simple swap of parts that I put into
my car so far has definitely increased performance bigtime!
My car handles better , moves better, everything better.

If you really need to go fast all the time and get speeding
tickets or whatever, than I would suggest buying a new
or used Camaro or Firebird with an LS-1 motor and 6 speed
trans. You can get one for about $15,000 to $18,000 used
with like 30 or 40k on it right now. I've driven one and
worked on one before. Wow, that car flys brother!


I don't see why I need to go really fast anyways, cause
I would get in a lot of trouble. But, I think I would still
do the motor swap anyways! Just for a hobby.

 

here we go again, swap a v8 in instead. yes, if you want to make some serious power gains that's the way to go. i'm pretty sure most people are trying to just squeeze a little more juice out of their 6.

if your good with wires, try upgraging your 2.8 to mpfi, that way if you ever want to go to a tpi v8, half the work is already done. your looking at about a 30hp gain going to mpfi, which can be done cheaply enough via junkyard parts or a wrecked donar car

 

Just a little story about 60* v6es.. Some guy threw a rod in his 2.8 s10.... it went through the block and a head.... was cheaper to comvert the car to a 350 than to put a new 2.8 in it........

 

I'm doing the same with my 3.1L MPI motor as well. I just
want to gain some extra power. Nothing crazy. But if I
ever want to swap a V8 motor and trans., the whole car
will already be set up for it.

I understand the whole thing about being on a budget or
don't have the time or even the money to spend on a V8
motor and transmission.

Right now, I just want to get some more juice of of the
V6.

Your right about doing a carb to MPI swap. Not only
will you gain horse power and torque, the car will run
much smoother and have a better idle than the old
carb version. I hate carbs, no offense to anyone here,
I just think it's a waste. TPI looks much better under the
hood than a big *** chrome air filter sitting on top of
the carb!
