hey guys im gonna be buying a 455 soon and was woundering which would be better to go with super charger, turbo or raise the compression. im woundering cause my uncle said some thing about that if i turbo or super charge it then i cant mess with the compression. the thing i would like to do is get the engine to make at least 500 to 600 hoarses but if possible keep it a sleeper:eek2: . i would love to beat my freinds brand new 06 gto and yes its the 6.0 hes always talking crap on how buicks suck so i ask plz help a fellow new buick owner.
It's all about the $$$. You won't be able to keep the stock pistons, rods, bottom end in general if you want the motor to last long. You will need GOOD machine work, components, and oil modifications to make it hold up. You can build a 600hp normally aspirated motor pretty easily. .038" over pistons, good ported aluminum heads, a medium to large cam, headers, intake, carb. It's being done all the time. Forced induction has not been done nearly as often on these motors, and you will have to know what you are doing. For the ultimate sleeper, turbos are the way to go. They don't need a radical cam, and you can keep it stock sounding. How much $$ do you have, and/or how much experience do you have? ________ Vaporizer affiliate programs
as far as experience i dont have any thing with fabricating or any thing like that as far as $$$ i have 2000 for right now how much hoarse power do you think that could even get?
If it were me... I'd find a good RUNNING 70-71 455, or 67-69 430. Do a compression check on it, and test the oil pressure. If necessary, rebuild the oil pump. Search the forum for oil pressure specs. Add a set of long tube headers. Add a Poston GS112 cam, dual valve springs, and 3500 stall converter. CHECK FOR PISTON TO VALVE CLEARANCE AND NOTCH PISTONS IF NECESSARY! 800 Q-jet on stock intake:Open up the idle circuits in the carb so it will idle with a big cam. or, find an 850 Holley and Edelbrock B4B intake manifold. Put a 1" four hole spacer under the carb. Add an MSD and pertronix unit, and get your advance coming in quick. Mallory electric fuel pump. 3.73 gears in the rear end. Go have some fun! Shift around 5400 RPM. This is an old proven combination that will put a GS into the mid to low 12 second range, and should be somewhat close to your budget, depending on what deals you can find. Unfortunately, Big Buick horsepower costs big $$$. By the way... this won't be a sleeper. The idle will be VERY nice though ________ Marriage advice forums
If you can fab, 2g's will buy you a bunch of power if you have a solid engine to start with. It's it's 100% stock with cast pistons, do not push more than 5psi if you want the motor to live longer than a few pulls. If you have your tune dialed in a stock motor should live a good long time 5psi. Start pushing more than that, and you'll start popping headgaskets and burning pistions. If you can fab, 2k will get you a nice turbo, blow off valve, some tubing, fuel pump, and a good carb to start moding for blow through. You won't be able to touch a charger for the 2k pricerange........
For the ultimate sleeper, Nitrous is the way to go. there, FTFY. turbos are the way to go. They don't need a radical cam, and you can keep it stock sounding. they got rid of the 'hair dryer whine'? when did that happen? as far as experience i dont have any thing with fabricating or any thing like that as far as $$$ i have 2000 for right now how much horse power do you think that could even get? yeah, BBB's turn 500-600hp all the time. but you're starting out with an extremely short budget to be trying to 'buy' all the hp instead of doing work yourself. my uncle said some thing about that if i turbo or super charge it then i cant mess with the compression. yeah, you can run super/turbo with high compression but you really have to know what you're doing. that's not something you should be attempting if: you've never used forced induction before this is not going to be a dedicated strip/race car you have a small budget three strikes and you're out on the "high compression turbo/super" idea. something else to consider if you go forced induction; do NOT get a 1967-70 engine. these all had 10.0:1 compression from the factory. you'll have a hard time running the base engine on mid-grade. forget about forced induction. but if possible keep it a sleeper:eek2: . you're never going to open the hood? pretty hard to hide a super/turbo charger if he ever looks in there. the easiest solution is just to sucker him into 'roll on' contests from 10mph or so with a stock engine. your part throttle torque will destroy him.
What year is the engine? FWIU you will need forged pistons if using nitrous with a goal of 500-600 hp.
If the motor is rebuilt (or at least very good running condition), then I would suggest many other changes first. For example: - Headers, x-pipe, and 2.5" (or 3") exhaust - Aluminum intake manifold - Cam upgrade - A switch-pitch upgrade for your TH400 and a mild shift kit - A good posi rearend (12-bolt posi, or 8.5" 10-bolt) - A high-quality ignition system- coil, MSD, wires, plugs, cap, etc. - Some fat rims & tires Once you do those, then see how much you have left. That will probably use most/all of your $2,000. If you do all of that stuff right, you might be able to reach the high 12-second range (which should easily dust your buddy's GTO). After you've done all of those things, and you still have money left, then let's talk! -Bob Cunningham
cool thanks the only thing is that unfortunetly its an automatic sry i forgot to mention that dont know if that makes a big difference for the parts.
Nope. In fact, the switch pitch tranny you could buy is a nice little feature many aren't familiar with. http://buickperformance.com/switchpitch.htm
