if its possible what is the cheapest and easiest way to get 300 hp out of a 95 3.4 camaro?

 

turbo, nitrous, and heavily modded. most of the cars that are N/A and heavily modded are only hitting about 200hp or a lil over. you arent gonna hit it N/A though.

 

get some good aluminum heads, custom ground cam, headers, ported intake and throttle body, throw on a turbo, boost controller and good ecm and youll get it but it will cost a **** load more than just putting in a v8.

 

i realize my replay is late, but you CAN reach 300 hp with the 3.4 in N/A form. All you have to do is grab the alluminum top end off of a 3.5 chevy malibu and swap it onto your engine. Have some custom headers made for those heads by john caraher over at 60degreeinclusive. Then, have a big custom cam made by comp cams. i would recommend 228/228 with probably 110 lsa/106 intake centerline. If you did go that route, you either need to change the pistons which would require rebuilding the engine. Or go the easier way and send those heads to john caraher and have him modify the combustion chambers to run those heads off of pump gas. Also have the heads and manifolds fully ported/polished is a must. Then you would have to worry about the tune since those cars are supposedly "untuneable". although everyone that says that are full of "****". You can tune that car, or any car for that matter, through megasquirt. Although megasquirt can get very complicated, there has been a few 3.4 camaros running megasquirt with much success. The easier route would be the obd1 conversion which john caraher could hook you up with. You could also have ed wright over at FASHCHIPS tune it for you because he tuned my 3.4 camaro. Only problem is that Ed wright is almost about to retire so i dunno if whoever takes over his company will be able to tune this particular ecm, but they should. If you have any questions feel free to ask. I have done SO MANY things to this 3.4 that it isnt even funny. The 3.4 is an awesome engine!

 

wow talk about an old thread, untill someone shows a dyno sheet on a hybrid as to what it makes at the wheels im going to say 300hp is gonna be a rough thing to do on an NA motor

 

It's doable, 300 hp N/A 3.1s have been done....not very streetable or easy to do, but def possible. But easiest and cheapest would be boost.

 

300HP @ the wheels or @ the crank?


Either way that's cake with a gen3 engine.

 

I'm trying to find the page, but there was a boat racing team that used a 2.5L-ish 60 degree V6 (destroked), that made around 360 HP IIRC. It was N/A, and used some of the best of the best parts around, including the Bow-tie block.

 

the term "3.4" and "gen3 engine" are mutually exclusive where 60/6s are concerned =/

Gen 1 iron heads, its going to be really hard without boost...

 

yes, you must have the aluminum heads to achieve that kind of horsepower. Preferrably the 3500 heads. I ran a 3.4/3500 hybrid for a little while with a 229/229 comp cam 110lsa and 110icl. I had trouble with the car running correctly and i blamed it on the 11.5 compression and the tune. I tried to tune it out with megasquirt, but failed. I know the car would run really well and be streetable if it were tuned correctly. Everything i did was copying another member on here who had success with his hybrid. His exact words about that engine setup, that i copied, was that " that thing would MOVE". I will tell you his user name as soon as i look it up.............

Here is the 660 I was talking about.

There used to be a page with more info on the engine, but it seems to be gone now.

i'd love to have those heads flowbenched..

 

That was part of the discussion on 660v6.com many years ago...

Man I just want to build a radical 660 NOW, not in a couple years when I can actually do it.

--==EDIT==--

I just looked at the dates of the old thread...

just noticed that it's got mechanical fuel injection, sweet.


the length of those velocity stacks kinda makes me want to add a few inches to mine.

 

Yeah, tuning the stacks has the same effect has changing runner length in a single TBI application, that uses a plenum.

The only difference with an ITB set-up, that doesn't use an air filter or box above the stacks is that the plenum is infinite in size. But runner or stack length and diameter have the same effect is each design.

I'm still toying with the idea of an ITB set-up on my 3500 when I finally put it in the Datsun. Still debating on whether to get that 3900 or not....

 

The advantage they have is that the ITB's are right on the intake ports, i still have the 3500 LIM so i don't think any calculation for velocity stack length will be accurate.

 

Doesn't matter, it's all length x diameter.

The bends in that length while they do have an effect, won't negate any calculation.

 

koolchriscamaro, you realize the last post before yours is 2007?

what I have readed 300 is a unicorn on our engines.

 

I would put some 3.1 liter heads on the 3.4... "The 3.4 air intake and exhaust systems are so poorly designed that it suffocates the motor without anyone giving it a second thought. While everyone is putting bigger throttle bodies and porting and polishing heads, they are neglecting the most important idea – “you engine only flows as well as the worst bottleneck.” With that in mind, ponder this thought: I asked James Montigny for his flowbench data from Norris Racing Tech on his heads. And then I asked a good friend of mine who specializes in the FWD 60 degree motor for a stock flowbench of the “3100” heads I had pulled from a 1996 3.1L engine and put on my car. The results shocked me. The stock heads from a 1996 FWD 3.1L engine flowed as good as the heads that were bolted to Tiago’s car (many of you know him as the one who developed a turbocharger for the 3.4L and pushed it to the edge)."

 

sorry to inform u but tiago did not push the 3.4 to the edge not even close
we have mebers here and myself have 2.8/3.1's making more power with half the boost as some of the guys with so called professionaly ported cyl heads


and btw this post has been dead for 3 years

 

Tiago had an awesome ride. 12 years ago.
He sold that car ages ago. It would have been interesting to see him stick with the 60* and push it, but then again can't really blame him for leaving. His current TA is a 1000 rwhp street car. (he's on a local forum)
I'd say the dude with the NA v6 that ran 14s pushed it pretty far.....

 

There's been a dude run 13s NA with a 60 degree V6...
