supercharged 4.3 or 5.7 swap?

  

blazerbeam -> supercharged 4.3 or 5.7 swap? (4/2/2008 11:07:05 PM)

which would be cheaper and which would be faster?


  
95LS -> RE: supercharged 4.3 or 5.7 swap? (4/18/2008 8:53:09 PM)

no offense but if you have to ask "which is cheaper" i would recommend not doing either. like the old saying goes speed costs money how fast do you wanna go? that should cover your question. if i had to pick id go with the 5.7. after you supercharge the 4.3 what else can you do down the road? youre maxed out. to get the most out of the supercharger and make it more dependable youre going to have to address aur/fuel ratio. how are you going to give the 4.3 more gas it needs to compensate for the boost? how much boost can stock internals handle (i dont mean for a few runs but how much can it handle all day everyday before you shoot pistons out of the hood?) might have to go with forged rods/pistons. not to mention if i was gonna spend the money id get a cam that will work with the supercharger better and may as well get the heads to flow better while youre at it. at this point why not go forged internals so you could really crank up the boost at this point the engine is gonna be tore down anyway. at that point i doubt youre stock tranny/rear end will handle that much power on a constant basis. time to upgrade them too. now you gotta worry about traction. what are you gonna do to hook the power to the ground. it dont matter how much HP you have if it cant hook. the point im trying to make is the list is never ending. and with all that money that you would spend in the 4.3 why not start with a 5.7? kinda like the whole import thing. you take a 2 liter motor (hell i have a 2 liter of mt dew in my fridge that is the same displacement) and spend the money to get the best engine parts/bolt ons around what do you have for the end result? to me a waste of time and money. you also have to consider that you want the truck to be dependable and be able to handle the power. when you talk about cheap you cut corners and eventually break stuff. then you gotta spend more money to put it back togeather. just do it right the first time and you wont have to worry and youll save money in the long run.

i apologize for being off topic but..blazerbeam..WHAT KIND OF GRILL IS THAT ON YOUR CAR? lol

mojoman13 -> RE: supercharged 4.3 or 5.7 swap? (5/1/2008 10:19:09 PM)

i dont really agree with the 2.0L being a waste of time and money.
a 180sx comes stock with 205 hp and all you need is a computer tune and you've got 225 WHP and it costs you what $500 bucks? that 180 will prob burn my blazer with my 325hp 350 in it. ive put $15 000 into my truck so far and i looked at a 180sx in mint condition with 225 WHP for $13 000
i have a tremendous amount of respect for japanese cars in that they are so efficient.
the fact that you can get huge amounts of power out of a 2.0L engine and still have some fuel economy is amazing.
my truck will get about 10MPG, that 180 gets 20MPG, both in the city.
now dont get me wrong i still live by the saying "theres no replacement for displacement" but i have a lot of respect for these japanese cars.

the thing with the honda engine tho is that those engines start out very weak so i dont believe thats a fair comparison.
it would have been more fair if the other car was a chevy aveo.
but you do that same comparison with the 455 v8 buick engine and a v6 2.5L RB25DET (Nissan Skyline GTR engine stock 260HP Twin Turbo) and i guarantee you will see different results.



95LS -> RE: supercharged 4.3 or 5.7 swap? (5/4/2008 7:40:56 PM)

its not all about HP. you have to figure in torque too thats what gets you going. the point of that article is that buick parts are expensive (i bet at least 2 times the cost of sbc parts) and the fact that you spend $3000 tops (with stock heads) and youre over 500 hp at the wheels (imagine if you put $3000 wisely in a SBC). it didnt mention torque but im sure its up there as well (my judge has a 428 that was rated at 390 hp and 473 ft/lbs of torque stock to try to give you a comparison). if you want to compare boosted engines stock look at the 09 CTSV (550+ hp) would put the Skyline to shame. i dont respect the import cars because anyone can boost anything and get decent numbers out of it. boost is the only way imports will get decent numbers.every car i have owned up to this blazer has been a rear wheel drive V8. my first car was a 89 GTA, my 69 GTO Judge, i also have a 86 C10. now the blazer (boooo v6). i choose to drive the right wheel drive V8 because of the speed (accept the C10 it has a 327 waiting to get put in then it will be snappy) not a wrong wheel drive weed eater on steriods. id like to expierence the handling of some imports. the EVO VIII was the only car at the time (maybe still is) that could pull 1.xx G on a skid pad stock. the only thing i can compare is the GTA has a WS6 suspension stock and that handled good. look at a Syclone that was the fastest truck (1/4 mile) EVER produced (think dodge ram R/T 10 and lightning). why? because it was AWD it would holeshot like none other. the point of that is it dont matter how much HP or torque you have if you cant get it to hook.

mojoman13 -> RE: supercharged 4.3 or 5.7 swap? (5/6/2008 7:15:13 AM)

your finishing line didnt really connect to the rest of your response.
but other than that i dont really understand why you dislike boost.
its just a way of getting the max power out of an engine.
and how you said the CTSV would burn the skyline? yes it would burn a easlier series but the new 09 GTR would put that cadi to shame. All skyline GTRs of all years come stock AWD and i've driven a couple and they handle like a dream.
Now im really not trying to cut down your cars, i love GTA's infact i have a 2 foot poster on the wall in my room but im just sick of the battling between domestic and import cars. We both have the need for speed and thats all that matters. So instead of battling we should share in eachothers intrests.


95LS -> RE: supercharged 4.3 or 5.7 swap? (5/6/2008 7:17:34 PM)

the point about my finishing line is that since the EVO VIII is AWD and it can hook and launch great thats another reason why it has impressive numbers. along with the syclones/typhoons. it dont matter how much HP you have if you cant get it to hook. i dont see the point in going with a import if you take any import stock vs any V8 and there is so much more potential with the V8. if i can build 400-500 hp car all motor what happens when i boost or spray it ? you have to get a lot of boost out of a import to get the same amount of HP and then what? you can only boost so much. another point of my link above was the cost to get to the 500 hp mark.  most of us cant spend $10,000-20,000 on engine work alone (not to mention tranny,rear end,.......) you talk about your skyline but how much will that cost to import one to the US? im sure you can build a car for a lot cheaper that will tear a skyline a new one with money left over. like i said most people are on a budget and it will be by far cheaper to build a V8 then a import.

mojoman13 -> RE: supercharged 4.3 or 5.7 swap? (5/6/2008 10:21:58 PM)

but i think your mistaken that they syclone is the fastest ever. the srts quarter is 13.5 and the syclone is real close at a 13.6 or so. i looked at a couple sites and those were the average times
but like i said it doesnt cost you $10 000 to get a import to 500HP.
i dont think you understand that the honda engines are extremely weak since they are not made for boost and are the bottom of the barrel for imports.
you take a GTR and put $5000 into it and you will have 500HP.
and i love how you talk about wanting more than 500HP
y would you want any more than 500HP unless it is strictly a race vehicle.
and another thing, a 500HP skyline can easily be a daily driver.
the car feels completely stock until you floor it and the turbos kick in.
i personally wouldnt want a 500HP V8 for a daily driver, i would definately as a toy but its too high strung to be stuck in traffic with.
oh and its funny, if you did some research or had a an idea what your talking about you would know that the 2009 skyline GTR is for sale in Canada and the US with a price tag of $75000.
so ya if i took say a 67 nova and put $20 000 into the engine it would burn the GTR in the quarter mile.
so it depends on what you want man.
do you want a daily driver or a toy to run around town or do you want a race car? i feel cars like the GTR can do all three as that 700HP 67 nova cant.

I'd rather buy a car that costs around 15-20k and put the remaining 55-60k dollars into performance, and destroy the stock skyline, for the same price.

It's called a Phantom Grille.  You can get 'em here, but they're pricey.  And they don't make them for '98+ Blazers.

As for the ol' ricer vs. musclecar argument, I lean toward mojo on that.  It's really like comparing apples with oranges, and depends on what you like.  I had a Maxima, which is not even in the same league as a Skyline, but I still loved it.  I also love my Blazer -- just for different reasons.

95LS -> RE: supercharged 4.3 or 5.7 swap? (5/8/2008 5:13:40 PM)

ok so you can get a skyline for $75,000. another 5,000 and youre only at $80,000. who on here has $80,000 for a car let alone a import ? or would want to buy one? or better yet if you spend $80,000 on a car it BETTER have 500 hp. i wouldnt build a nova,slowmaro, or chevelle everybody and their brother has one. i have a 69 GTO Judge for a reason. its quite a bit rarer then those other cars. youre right 500hp isnt streetable at all. thats why it is a toy. i wouldnt need to put $20,000 into my engine to burn a skyline. yes the syclone is the fastest truck ever produced (1/4 mile time). let me go to my local nissan delership and see what they tell me when i tell them i want a skyline. i think i would get laughed out of the dealership. the point i am making is on a budget some of us dont have a $80,000 budget for a car (ive seen houses for sale cheaper then that) it will take less for a V8 to get 500 hp then a import. period. end of story. you can grasp at the ultra rare ultra expensive imports and say well this will beat a V8 but if youre going to compare 2 cars at least compare apples to apples. compare a ultra rare ultra expensive V8 to the same import and youll get the same result.

mojoman13 -> RE: supercharged 4.3 or 5.7 swap? (5/8/2008 9:45:53 PM)

well the skyline has 475hp and ya i totally agree i personally dont have 80G's but your saying that every car that your too poor to afford is a waste of money. farrari, lambo, corvettes, vipers your cutting them all down cause you know you will never be able to afford one. and 500hp is streetable in a import but not as much in a big V8.
oh and i was really bored and i finally read that stupid article and this is the comparison.
140hp 1.8L vtec   to 500hp   = 360hp gain     = 10500  = 29.11111 dollars per hp
350hp 455 v8       to 500hp   =  150hp gain    = 4000   = 26.6666 dollars per hp
i cost $2.50 more per horsepower to get the honda up to 500hp and that honda engine is one of the most costly to improve hp
swap out the honda for a car with closer hp
92 supra TT 280hp
280hp 3.0L v6  to 500hp  = 220hp gain   = 5000     = 22.72727272 dollars per hp
costs 4 dollars less per hp to get the supra to 500hp
(based on google seaches found two sites both said to get 500hp would cost 4000 but i rounded up to 5000 just to be safe)

and look cheap fast cars that i could pick up tomorrow if i wanted.

little bit more for the GTR but its a 13.0 second  car....
http://www.redlineimports.ca/Candianstock/GTR-07-01-10/GTR-07-01-10.htm
335WHP and 300ft lbs of torque (i thought u said imports dont have the torque it takes to get going, guess you were wrong)

Price of cars listed here includes the out of province and mechanical inspection being done, GST, and total cost to bring car to Edmonton, Alberta. Cars will be ready to register in the province of Alberta upon being sold

they are affordable and dam fast too.

you should pick one up some time

95LS -> RE: supercharged 4.3 or 5.7 swap? (5/10/2008 2:18:31 PM)

well if you think 300 ft/lbs of torque is a lot then i guess i am wrong. keep in mind the buick 455 is a lot more expensive to build then a SBC. or even a BBC. just like you say the honda engine is more expensive to build then whatever (all i hear about is a skyline but i dont knwo what would be cheaper to build then a honda) and the buick had stock heads. the only "major" upgrades were headers,cam,and port work to the stock heads. oh yeah and its all motor car. they spent $3900 on the buick ($10,900 for the honda with 33 lbs of boost). everything was upgraded with the honda. with the $7,000 left over you can be well over 500 hp. and get you in the 10's at least. heres another point as to all motor vs boost. look at NHRA super stock rules (all motor car is the biggest thing) and see what times they are running. i have yet to see any import (not that i pay that much attetion to them) with boost get close to what a nhra superstock car will run. have they even broke 10's yet?

mojoman13 -> RE: supercharged 4.3 or 5.7 swap? (5/10/2008 2:43:05 PM)

how fast do those NHRA super stocks run?
theres a whole bunch of huge hp imports doing crazy quarter miles like this skyline here
http://www.youtube.com/watch?v=WFLjKQ8N_C0
quarter mile in 7.92

completely street legal supra that does 9.0 at 160mph
http://www.youtube.com/watch?v=R4605AJ-yac&feature=related

skyline that does 7.5

95LS -> RE: supercharged 4.3 or 5.7 swap? (5/12/2008 9:02:07 AM)

ok are these surerstocks or are these just built ? there is a diffrence. thats why i said find a import that runs superstock. NHRA superstock you have to use factory block and heads and carb (for muscle cars) you also have to have a full interrior.  the only mods allowed are headers,intake, and valvetrain. there is a minuim weight requirement i believe it is 3,000 lbs. also they burn pump gas ( not racing gas) id like to see a import with 20-30 # of boost run on pump gas. keep in mind there are over 80 classes in superstock. so out of those 80 classes find me one import that will run better then a domestic car. if you want to go with more of a outlaw exaple you will end up with this.

these are strictly pontiacs
http://forums.performanceyears.com/forums/showthread.php?t=458469

the thing you dont understand is the faster you go the more power it will take. it will take less to go from 10.0 to 9.5 then it will to go from 9.0 to 8.5 (thats why i say you can only boost so much) more boost= more cylinder pressure thats why youll see head gaskets (for one exapmle) blowing. ive been talking about engine numbers (hp/ torque) once you get those numbers you still have to have it hook up and the rest of the systems have to work as well (enough fuel,strong enough drivetrain,....) not to mention having a chassy that will handle the power as well. what was that about your skyline now? on the pontiac list alone that will get you somewhere between 11-13 not to mention any of the other makes that will run just as fast if not faster. and that video was the fastest skyline run ever. i cant wait to hear your responce. 

mojoman13 -> RE: supercharged 4.3 or 5.7 swap? (5/14/2008 9:49:52 AM)

i dont get it
we go from compairing imports to domestics and the cost to raise the horsepower in both right
then you have no points left so you say how domestics are better at super stock racing
ok i give it to ya if you wanna make a super stock 7 second car go domestic for sure but if you want the fastest car you can drive on the street you go imported.
like ive said before it depends on what you want
and our arguing is dumb because we both have valid points but the thing is that we want different things.
i dont want a car that can do 8 seconds at the track if i cant drive it on the street
in my opinion if you put 30k into a car and all it can do is rip it up at the track then thats a waste of money.
but remember thats my opinion right.
i would rather have a 700hp import that will beat anything and everything that pulls up next to it at the lights.
and with 700hp in an import it is surprisingly not a very rough ride
they can be stuck in traffic without a problem they can be a daily driver.
and thats what i love, that you can drive it to work everyday.

swartlkk -> RE: supercharged 4.3 or 5.7 swap? (5/14/2008 11:14:04 AM)

This is an age old discussion.  It all depends on what you want.  If you want an import, you will get an import.  If you want domestic, you will get domestic.  They both are capable of doing what you want them to do.

To say that you can do one thing in one and that you cannot do that same thing in the other is ignorant.  It goes both ways and I think it should be left at that. 

Talk of money just complicates things as that is highly dependent on the vehicles being discussed.  As both of you are mainly speaking in generalities, it is pointless to bring money into the equation.  There are always options that can refute even the best laid out statements when it comes to this type of a discussion.

Then there is always the 'fast-n-furious' mentality that has so many infatuated with irresponsible stop light ego trips.[&o]  Keep it at the track!

95LS -> RE: supercharged 4.3 or 5.7 swap? (5/14/2008 11:30:04 AM)

my point is that this guy is on a budget just like most of the rest of us. if the V8 has 300ish hp to begin with (old school mucle cars will have more but well stick to 300) its gonna cost less to get you more. less money and a faster car. and street driving wont be a problem. you can buy vaccum canisters that will give you vaccum for power brakes while youre stopped at a light. as logn as you pick the right cam you wont have any issues as far as idle and still be able to beat imports. the point i made with those last 2 links was that if you dont compare apples to apples ( superstock cars ) and go with the outlaw approach the V8 will win everytime. i have yet to see a import superstock run faster then a domestic.
