the problem is that the only tunning avalible is mail order and they can do basic stuff (gears, top speed, intake, exhaust, timing, ect) but they won't do any major fuel table tuning and the more advanced things because they do not know what the car needs because they have no experence with the 3.4, we need someone that is willing to spend some time on a dyno and burn a chip then run the car then tweek the program and burn another chip and so on and so forth till they get it right, but you will find no one willing to do this because the market isn't big enought to spend that kind of time doing this, and if you do your going to spend a fortune to make it worth their time

^ X2 , ken is wise

there is no good tuning our there unless you take it into your own hands and get a stand alone system


240 WHP is not that impressive with this motor IMHO.. especially if thats on the bottle </font>[/QUOTE]for the amount of money that was put into that motor i'm really not impressed, which is why...sadly I will be swapping to a carbed 383 in the proceding years. Unless you get a stand alone system and do a 3.XX swap like Russel and Aaron you can't get the full potential of the 3.4 IMOP

Would a carb'd 383 even fit in a F-body? I thought carb'd 350s took a LOT of modification to get in. Due to where the engine sits.

if you can get a 350 in you can get a 383,

a 383 is just a stroked 350

Yea the 350 and 383 use the same blocks and there is no way to tell the difference form the out side.
I don't think the 4gen k member comes ready for V6 or V8 motor mounts like the 3rd gens did.

[yellowfbod]

there are some modifications required such as cutting almost all the cowl out, swap the k-member with a tubler on or stock Z one with SB motor mounts, strip out most of the wiring cause it is not needed and rewire the car with a painless 12 circut panel (not required but makes things alot eaiser), new radiator, make my own gauge cluster, trans cross member to support the turbo 350, ect. etc. Buts its really not that bad, before you ask yes it would be easier and cheaper to buy a Z but how original is that and I don't want to do a LT1 swap cause I am tired of the whole computer crap.

well seing as how they make a big block K member for our cars id say a 383 wouldnt be a problem

[black34v6]

i went from 142rwhp / 185rwtq -&gt; 170rwhp/207rwtq (and that was with parts from a FWD 3100 aluminum head engine (3.1L) + my cutout open.)

i havent dyno'd with the 3400 parts yet. i will soon.

changing the topend is a bit of work, but not as hard as tryign to drop an 8 into a car that had a 6 in it before. also not as costly.

[BiH]

so what parts from a 3.1 FWD engine did you put in your camaro to gain that much hp and tq?

[black34v6]

Ok. So the best setup is to get all the parts from a 3400 engine -- (3.4L FWD Engine - Grand Am GT Car)

that being said the power was obtained using:
1996 3100 Gen II Aluminum heads
1996 pushrod set (cause they are varied length and you cant use the stock 3.4 RWD ones)
2000 Fuel Rail and Injectors (19# instead of 16#)
1996 3100 lower intake manifold
1996 3100 plenum sanded smooth (otherwise it doesnt fit - no clearance above.)
RKSport headers (or pacesetter, just know that the stock manifolds DO NOT bolt up to the aluminum heads)
2000 3400 (3.4L FWD) Throttle Body
Pistons that fit the 3.623" bore, but that are for the Aluminum heads (tell the compan you are ordering from that you need pistons for a 2000 Grand Am GT - the "LA1" engine or a 3400 FWD)

the total cost of the engine (because i rebuilt mine) + all the little parts and fabrication i had to do ran me around 2000.00 -- that included the 1200.00 rebuild price.

so for all the parts + parts i had to get to fabricate stuff - its around 800.00 for this mod.

that includes the 500.00 RKSport headers. (yes i spent less than 300.00 on the heads/intake)

anyway. all this is well worth it i think. because right now (according to the way drivetrain loss works) since i have a manual transmission, i was losing 15% through the drivetrain when that dyno was done.

so by that math:

170 rwhp / .85 (15%) = 200 hp
207 rwtq / .85 (15%) = 243 lb ft.

and i can deal with that. thats more than enough to keep up with/beat 3.8L fbodies. you can keep up with most of the mustang GT's (The newer ones) and really dust the 3.8L Mustangs. its enough to beat 305's (stock) and since the 3.4 is lighter (you save 100lbs at least from the heads) you end up speeding yourself up that way too :-D

the whole process took me (With the rebuild) 2 months. but thats cause i was waiting for 1.5 of those months on the stupid shop to build my motor. (guys couldnt figure out how to get the right pistons.)

do a search. my posts on swapping the iron heads to the aluminum heads are still on this board..archived somewhere. if i can find em ill post them up for everyone to see.

edit: oh yea. forgot to mention. the 170/207 was with my cutout open (no cat/no muffler). with a muffler (flowmaster 3" catback system) the car ran i think 168/203 or something like that. which is still a decent gain from 140.2/183..imo anyway.)

ok man thanks alot

[StudlyCamaro]

and hte 2000+ 3x00 parts are much better than the 99 and below parts, russell, get that **** to the track!

['94firebirdv6]

so if i understant this correctly...there are aluminum heads that will fit a 3.4? [img]graemlins/rock.gif[/img]

all you need is money. with money in any car can make your motor go fast. you mentioned all you want to do is beat the si. is that your goal then not much needs to be done. but if you want respect then port and polish the car, cams, gears, suspension, power adder, tuning, and etc.

[BiH]

when I polish my car it only looks good,but it doesnt feel any faster [img]graemlins/rofl.gif[/img]
