very new to modding a car but my first mod is going to be making the cylinders a bit beefer im thinkin 1/8 bigger.

do you guys think thats a good measurement like is that the basic of how much bigger you should go for playing it safe ???? im kind of confused on boring but yeah due tell and how much would i cost and what not

FeaRlezZ · October 16th, 2011, 08:25 AM

so let me get this straight . . . u are "VERY" new to modding cars and the first thing u are going to do is tear open the block and hone out the cylinders ??????

dsm2mivec · October 16th, 2011, 08:28 AM

Man I think you need to buy a flame suit first. Then search a little and look at the newcomers thread for beginner mods!

akley88 · October 16th, 2011, 08:29 AM

cost would depend on where you can get it done. but theres more to it then just boring and honing the block.

hackerd · October 16th, 2011, 08:33 AM

At least he's not asking which CAI intake he should get.

CrAnSwIcK · October 16th, 2011, 11:15 AM

1/8" is quite the over bore...lol, usually you measure over bore in thousandths...and the guys are right there is more to increasing displacement than just boring and honing the cylinders. And machine work is quite expensive.

devlin · October 16th, 2011, 12:51 PM

god dammit!!

dejectedangle · October 16th, 2011, 12:56 PM

Boring removes metal does not make it "beefer"

devlin · October 16th, 2011, 12:59 PM

i thought that was a legit question look i read about the beginners to modding i get it first get the cold air intake exhaust etc etc etc. fuck that i hate it when you see a 4 banger with this obnoxious farting sound i want to be a bit different i would not just make the cylinders bigger i know theres more to it always is "at least i know that" and if i want to go spend big bucks with my car i would just save up for a sc rather then spend over a grand on 7ish extra hp. so is my statement ridiculous or respectable ?

snakeeyes · October 16th, 2011, 02:21 PM

idk where you came up with a grand for 7 hp.$150 for the pulley will get you that lol

devlin · October 16th, 2011, 02:29 PM

lol i was guessing but i ment that for the cost of a full exhaust

my custom exhaust cost 200 bucks. boring like you would want would be expensive cause pistons will cost more and since your doing that you would be smart to replace the rods. that adds up quick

mrgibs121 · October 17th, 2011, 03:15 PM

boring isnt going to give you very much.... maybe a few 10s of cubic inches if youre really lucky... (sorry the only engine ive bored is a chevy 327 so thats why im talking in cubes). what really increases displacement is if you manage to stroke the engine (change the crankshaft to have a larger radius of rotation therefore increasing piston travel) this is really expensive, maybe even impossible on this car due to lack of parts. in fact im willing to bet it would be CHEAPER to straight up go FI... no such thing as cheap or easy power... if there was it would have come from the factory like that, dont ya think?

There's a guy that talks my lingo

My first build was 327 Camero...bored and stroked it and made a 356 out of it. It didn't rev as quick as the 327 but the torque was out of this world

I'm going F/I but still planning on boring and installing the new pistons and rods I have already purchased. Going to install the SC first and will most likely blow my motor trying to get a good tune and then will do the lower-end build. The reason I'm boring though is for the new pistons and rods....would not do that for power gains alone.....I need to drop compression, install forged pistons and rods to take the extra stress of the SC.

You guys like American muscle? How bout my 600 hp 68 chevelle 427 big block bored 30 over with a 671 blower roller everything roller cam lifters and rockers the car is sideways in 5th gear at 60 mph runs on 87

Sorry for OT

Looks like you could suck up a flock of geese if they flew too close....what a beast!

Slippercream · October 22nd, 2011, 02:49 AM

Do NOT attempt to bore and hone an engine if you have no experience, or do not have the right tools. First off, no one can tell you that XXX mm or in is "safe". Every block is different. And the only way to truly know is to have the block sonic tested.

Either way, this cannot be done with just eyeballing and elbow greasing. You need an experienced and well-tooled shop to do this.

You've got a long way to go, man. Don't screw it up by jumping into murky waters. Keep it simple and fun while learning in the process. Then go from there.

leet · November 10th, 2011, 09:37 AM

it isnt expensive. prolly run you about 200-300 to bore and hone all four. the cost is taking out the engine and putting it back in.

joeyb · November 10th, 2011, 04:58 PM

wow that blower is a monster.

dev - if you are going to "bore" your block, you really want to get everything you need to just build your engine completely. as they guys point out, just doing an over bore isn't going to buy you all that much. now, forged components and headwork to combat valve-float, then getting an FI set up or a fat bottle to go with the build, you'd be sitting at or near the top of the GS food chain.

I was just posting about how no GSers have built their engines yet....

mwaterous · November 10th, 2011, 05:07 PM

We don't really have a GS food chain. It's more of a soup line. Every once in awhile you hear somebody yell "I found me some new socks!" and we all dote over them for a little bit.

Moyer627 · November 21st, 2011, 02:42 AM

Another thing That nobody else mentioned that went through my head. Now I don't know a whole lot about this newer equipment but I did a alot of work on old Chevy motors. Now when you bore out the engine you are giving more space for the cylinders which on a Chevy engine which burns rich as hell isn't a big deal but on this newer stuff you might also need to figure on getting more fuel into those cylinders to compensate the extra room which unfortunately can't be done with the turn of a screw like a chevy engine. You have to buy a control module which is pretty pricey. Also I don't quite understand how you got enough bore out of a 327 to make it a 355 I had a 30 over bore on my 79 350 and that was considered a 355. I think you can only go 60 over with a 350. That just sounds a little unrealistic with just a bore. Maybe not I think it is the same block. If I were you I would start with every bolt on possible which isn't very much with this car then get a cam and take it to a shop have the cam and bore done at one shot then tune it right away.

Moyer627 · December 13th, 2011, 12:30 AM

I found an oversized piston set on import performance parts. You can go 20 or 40 over also claim to be higher compression pistons dunno what the stock compression is so I didnt look at that. http://www.importperformanceparts.ne...itsubishi.html I bought my 4g with 80000 on it with the intent of a full rebuild. I think I can get at least 250hp out of this engine with full internals. And full bolt on. We shall see. I just gotta find a block to start with.

Moyer627 · December 13th, 2011, 12:40 AM

To answer that question I've had alot of experience with it with the exception of I get the block punched out by a machine shop. You don't get a whole lotta gain from it but still more than bolt on parts. Your best bet is to figure out what it needs to be bored to to eliminate any scars or burrs. Then you go at least that bore. Also honing is only done to smooth out the cylinders. I wouldn't do the machine work either, I would take it to a shop used to be like 50 to 60 bucks a cylinder.

akley88 · December 13th, 2011, 01:51 AM

the stock compression is 9.5 to 1

2fast4u · December 13th, 2011, 01:54 AM

i likee that this guy has bigger plans than boltons, but dude, i wouldnt bore an aluminum block if your going to fi. Warping might/will be an issue. I would just go fine someone that knows how to weld and grind really well and get you a stage 2 cam w/ roller rockers and stiffer springs. Get someone with a good machine shop to do a p&p on your head, plenum, and im and port match it all. It would cost less than boring your block and give more power gains. I think i remember one dude saying he swapped his head with an evo and gained 40hp. Boreing will maybe get you about 10hp and its major surgery. I wish you best of luck. And those stupid boltons you were talking about, will bring you 30-35hp at the crank. Even more with head work and a cam

Moyer627 · December 13th, 2011, 02:00 AM

Right I understand that but I wanna do the boring and top end and rods, and crank if there is a better crank I want a fully built engine. I'm very undecided on fi. Never did it before if I would it wouldn't be past like 8 psi plus higher compression is bad for turbo.

Moyer627 · December 13th, 2011, 02:04 AM

I also think its gonna cost more or at least the same for the cam cuz to do that I definetally need the aem fic and a tune. My plan is to finish bolt ons to this engine get another block and build it from the ground up. Then swap what's on mine to that one. When it's all installed tow it to a tune shop and see what this little motor got.

2fast4u · December 13th, 2011, 02:23 AM

thats an awesome plan, id like to see it come to fluition. Our motors as it sits can handle 8 psia. After that youll have to decompress. Our block is an ohc so it wont cost near as much to get it done, you dont have to take the engine out. Buy you a pos project car, tear that fucker apart and put it together. When you understand the workings and what all is required then mess with your dd. Dont pay a shop thousands of dollars in labor to do what you can do yourself.
Go turbo and do the top end like i described and youll be gs king. Id like to see it run against a gt after that. Mmmmmm.... A gs that slaughters a gt. Sex.

Moyer627 · December 13th, 2011, 02:29 AM

Na dude the only thing any shop has or will touch on my car is boring the cylinders, if there is an oversized crank then the machine work for that and the tune. I've built some pretty interesting things very knowledgeable about motors but I always did v8s but there's a group of about six of us that all work on each others shit. They are mostly Honda guys but I'm the only guy that's not a certified mechanic. I mean the one kid is pushing over 400hp in his hatch Honda with a b16 if he can do it so can I.

2fast4u · December 13th, 2011, 02:33 AM

Our "little motor" is actually a very large 4 cyl. Any larger you enter v6 territory because the torsional vibration (forces of the combustion twisting the crank at a given frequency) would tear the engine apart. Then your crank would go all pixie dust on you.

2fast4u · December 13th, 2011, 02:46 AM

and i bet you a good majority of that is due to head design, cam duration, lift, and an amazing aftermarket for honda/acura. If that lil 1.6 l dohc can get that volumetrc efficiency ours could get about 500. If you get this big ass sohc to push 400, i sir... Will let you fuck my sister.

Moyer627 · December 13th, 2011, 03:47 AM

Ha I am almost married with kids so yeah no can do. I dunno if that is possible but at the same time all I have read on here is speculation from everybody on the 4 cylinder and all I have seen is bolt on performance numbers. I think this motor has a lot more potential then given credit. I dont care if I can beat a gt either I don't even race anymore I just love working on this stuff. Shit man my boat has more hp than my car that's just unacceptable.

2fast4u · December 13th, 2011, 04:34 AM

sorry it took a while, my phone decided it was gonna fuck up so i had to wait till i got off work

Warping might/will be an issue. I would just go fine someone that knows how to weld and grind really well and get you a stage 2 cam w/ roller rockers and stiffer springs. Get someone with a good machine shop to do a p&p on your head, plenum, and im and port match it all. It would cost less than boring your block and give more power gains. I think i remember one dude saying he swapped his head with an evo and gained 40hp. Boreing will maybe get you about 10hp and its major surgery. I wish you best of luck. And those stupid boltons you were talking about, will bring you 30-35hp at the crank. Even more with head work and a cam __________________ The nicest asshole you'll ever wanna meet Mods-custom sri, federal 595ss tires, driver mod-400k professional mi driven Coming soon-gt tb, rre underdrive pulley, rre headers, headerback exhaust Begging wife for, fi/c & wideband, t3 turbo and all the works, my nuts back.

I'm very undecided on fi. Never did it before if I would it wouldn't be past like 8 psi plus higher compression is bad for turbo.

My plan is to finish bolt ons to this engine get another block and build it from the ground up. Then swap what's on mine to that one. When it's all installed tow it to a tune shop and see what this little motor got.

Our motors as it sits can handle 8 psia. After that youll have to decompress. Our block is an ohc so it wont cost near as much to get it done, you dont have to take the engine out. Buy you a pos project car, tear that fucker apart and put it together. When you understand the workings and what all is required then mess with your dd. Dont pay a shop thousands of dollars in labor to do what you can do yourself. Go turbo and do the top end like i described and youll be gs king. Id like to see it run against a gt after that. Mmmmmm.... A gs that slaughters a gt.

I've built some pretty interesting things very knowledgeable about motors but I always did v8s but there's a group of about six of us that all work on each others shit. They are mostly Honda guys but I'm the only guy that's not a certified mechanic. I mean the one kid is pushing over 400hp in his hatch Honda with a b16 if he can do it so can I.

Any larger you enter v6 territory because the torsional vibration (forces of the combustion twisting the crank at a given frequency) would tear the engine apart. Then your crank would go all pixie dust on you. __________________ The nicest asshole you'll ever wanna meet Mods-custom sri, federal 595ss tires, driver mod-400k professional mi driven Coming soon-gt tb, rre underdrive pulley, rre headers, headerback exhaust Begging wife for, fi/c & wideband, t3 turbo and all the works, my nuts back.

If that lil 1.6 l dohc can get that volumetrc efficiency ours could get about 500. If you get this big ass sohc to push 400, i sir... Will let you fuck my sister. __________________ The nicest asshole you'll ever wanna meet Mods-custom sri, federal 595ss tires, driver mod-400k professional mi driven Coming soon-gt tb, rre underdrive pulley, rre headers, headerback exhaust Begging wife for, fi/c & wideband, t3 turbo and all the works, my nuts back.

I dunno if that is possible but at the same time all I have read on here is speculation from everybody on the 4 cylinder and all I have seen is bolt on performance numbers. I think this motor has a lot more potential then given credit. I dont care if I can beat a gt either I don't even race anymore I just love working on this stuff. Shit man my boat has more hp than my car that's just unacceptable.
