ok, i'm looking to do the 086 head swap and i'm also boreing out my cylinders .020" and the pistons i'm looking at are the wiseco K584M905 that are already made for a .020 overbore, BUT are they proper enough to lower the compresion ration so i can run 91 to 93 octane gas and not HAVE to run anything higher, but can when racing. i read something about this subject before but the thread is old and i didn't want to revive it for no reason. they talked about using copper shims on either side of the gasket. Also i will want to run some boost much later on, but i want it to be able to perform when i'm ready for it. thanks for the help.
I also am doing this swap...I didnt look up the part number of your piston but if its 9-1 compression ratio w/ factory head It will put you around 10.7-1 compression w/ the 086. On this compression you can run the cheap gas...boosting will be another story.
^^^^What Cory said
I have those exact pistons. 87 octane all day. When I get my MS-II I will tune for 91-93.

"Youth in Asia"...I don't see anything wrong with that.
Contact Karo at Car Customs. I got some Weisco pistons that are made for the LD9 with the 086 swap, 0.020" over using a 0.043" head gasket and valve pockets for the HO cams....all with a 9:1 CR final. That way I can still boost pretty well too.
the only thing is that car customs doesn't ship to canada. i'm able to get the pistons, and eagle rods at garage price from a friend, but it'll be almost $1100 (keeping in mind canadian currency). car customs any cheaper?
I'm not sure... but there are ways to ship into canada using a signiture confirm(not cheap) but it is possible. I'm sure the only thing keeping Karo from shipping to canada is the high rate of lost packages and the inability to insure the packages get to his cutomers. But if what your shipping is pistons I dont think $50.00USD(just a guess for insurance, tracking, and signiture confirmation) for shipping would break the deal off.....contact him and ask.
The pistons I got are more than standard Weiscos so the short answer is no, you can't do it for $1100CND with eagle rods.
Karo ship to Canada. How do you think I got most of my parts. You need to contact him by email. 1100$ is expensive. If I take the price I paid for the rods and custom 12:1 pistons from Karo, it would cost me around 950$ shipped. Karo shipped them to me 2nd day air with UPS so you don't pay brokerage fee, just customs and shipping.

yup, got my set of rod, pistons and alot of other parts from him!! great to deal with...
i don't mind using 91 or 93 octane pump gas. but with an 8PSI turbo setup, would i be pushin to much onto my block and pistons since they would already be at 10.7:1 or would i just need to run a higher octane. thanks for the help, you guys are life savers
I'm not sure I hear about inmports running 12:1CR and booting still with no problem. I say buy HPT or a stand alone ecm and tune the car. You can run any CR with a good tune and boost.
In the planning stage for an all American TRD Cavalier.
the only thing though is that imports are very different from our j's. all of their cars rely on tuning. that's all they are, they have no real balls, just timing. that's why all the computer geeks just gettin out of highschool pick up a pocket tuner Honda cuz they are much more comfortable with ecu tuning and computers then they are actually working on a car. ever notice how most of the civic's and crap all get taken to a professional garage to have work done cuz they have money, just no actual engine modding knowledge.

Really? I find it hard to differentiate between the engineering behind one gasoline powered, electronically controlled, internal combustion, piston powered, transverse engine FWD vehicles.
"all of their cars rely on tuning."
I'd like to know your definition of "tuning", and how the same things that would be beneficial to any imported car would not be beneficial to your Sunfire?
"hat's why all the computer geeks just gettin out of highschool"
Birthday: May 3, 1988. Pot<--->Kettle anyone?
"they are much more comfortable with ecu tuning and computers then they are actually working on a car. "
Once again...how would this be beneficial to a Honda and not to your vehicle?

what does my birthday have to do with anything? and what the hell does pot and kettle mean. old timer sayings i guess. and i didn't just get out of highschool if that's what your trying to imply i've been in college for a year now, i had an early dissmissle from highschool because i was ahead of the rest of my classmates. and no, it wasn't computer engineering. what i was trying to get at is that it is alot easier to tune a Honda, compaired to a GM car. that's it. there is more information and more support for the imports, i'm not bashing them (even though i do hate civic's being on every left turn i make.) but the tuning aspect of reflashing the ecu, wiring everything and just the basic overall programming of their computers is much different then ours. but let me guess, you've never worked on a honda that indepth before so that's why you're basing everything u just said of off the "i like to play the penis showing game" and say everything you know about 4 bangers. whoopy @!#$. still doesn't change the fact that everything you just listed was very open and not specific to a Honda and a GM car. you listed everything that's in every 4 cylinder. i'm talking about details, differences between the 2.
"the only thing though is that imports are very different from our j's"
"Really? I find it hard to differentiate between the engineering behind one gasoline powered, electronically controlled, internal combustion, piston powered, transverse engine FWD vehicles. "
..that's awesome you have such a large dick and all, but where in my statement did i say the basics of internal combustion engines were so extravicantly different?.....twit.
"they are much more comfortable with ecu tuning and computers then they are actually working on a car. "
"Once again...how would this be beneficial to a Honda and not to your vehicle?"
i was talking about the people that work on the cars, not the car itself. most of them don't know @!#$ about replacing a head gasket or installing new rods or valve springs. they take their engine to a mechanic/machinest to get them to do the work, and then they only deal with the computer. again, where in my statement did i say ANYthing about it not being benifical to my sunfie, or any GM car. I love when people think they are so smart and try to bring up irrelevant babble to show someone up. eat me.
I'm with Zline on this one. You need to learn alot more before even thinking about modding your J.

while he's at it he mine as well take the block to the machine shop and have them bore out the cylinders .020" then he could just order some wiseco overbored pistons and eagle rods. that way he doesn't have to get custom made 8.5:1 pistons cuz the overbore lowers the compression ratio on it's ownputtin him at about 10.7:1 i'm doing this same setup, already ordered everything, just waiting on shipment. although i'm doing secret cams, not HO cams.
I quoted you in the other thread because you said that. That right there showed me you know nothing about engines and modification.
All the cars are the same. Same way to make power. ALOT of the honda guy are not even tuned right just like the J and other platform. If you think all the Honda guy tune their Ecm and that's all they do, sorry but open your eyes. About 50% of the people who bought Hp tuner don't even know how to use it or what to change but they still try to tune their car.
You just don't have enough experience to know and understand how things works. So yeah, 1988 play a big thing here. I've seen ALOT of guy like you go around and think they could build cars but they pretty much all end up with a CAI and a muffler then talking crap.

Tuning is "THE" way of making the most power out of any car. Hondas are exceptionally responsive to tuning, because they can simulate different cam profiles based on their VTEC technology so that they can run ridiculus cams and still remain streetable, whereas a conventional motor (like ours)is limited. That is one of the reasons why engineers take very well to hondas
Hondas also have far more aftermarket boltons and internal components available to them than all six j-body motors put together, and many of them don't pay someone else to do the installs for them. So to say that they don't know how to change something as simple as a headgasket is rather ignorant. I will agree, however, that there are plenty of riced out civics with owners who couldn't turn a wrench to save their life, but I can assure you there are just as many riced out J-bodies with owners who couldn't either.

lol i would do that, but i have more ambition. i'm sorry if i turned this into a poo throwing thread, didn't mean to i just got offended cuz people just assume stuff yet you don't know me. i've already bought an LD9, i already stripped it down i just finished helping my buddy build up his LD9 as well, so i'm pretty set for doing my own. if i @!#$ up, oh well i learned by doing it. but just because i'm 18 soon to be 19, doesn't mean i'm utterly hopeless. and the comments i made about ricers, (excuse me for sounding biased) were about the people in my area. None of them know anything about cars and they only have an exhaust and intake and they do talk @!#$. i'm not like that, i'm going through the motion of learning about building engines. mine will be done as soon as i get my block back from the machine shop then i can do the oil pump conversion, and drop the LD9 in my 2.2ohv sunfire. already have the wiring harness and ecu from a 98. i'm not COMPLETELY useless. sorry if i offended anyone.

Hey, no blood, no foul. Your first post gave the impression that you had the "I want me one o'them ol'-fashion' cars...gimme a Chebby, not some computerlized Honda" attitudes. You made it sound like there was a huge gap between modifying a Civic and modifying a Sunfire.
The birthdate thing? Had to bust your nuts on it, simply because of the high school comment. You MIGHT be an exception, but for the most part, there's no difference in maturity between an 18 year old high school senior and a 19 year old that graduated a year ago. Like I said, you could be an exception.
