Ok i have been boosting 8psi for a little now and its been nicebut i yearn for more, so i watch field of dreams the other night and went to sleep afterwards and hear this faint voice wispering ," if you build it boost will come "
So i wanna build the block to see what this all means
I was just gonna go simple and go either JE or Weisco Pistons 9.8:1-10.0:1, and Eagle Rods.
Now im thinking about getting Darton sleeves or soemthing too . . . well what i wanna know is do you guys think its worth it to over bore it to whatever like a 2.0l to get the extra displacement , or just stick with standard bore, I can only think more displacement = more power , are there any more cons/pros about it .
also what is the displacement of a b series motor ? i know it sounds stupid , but i really dont know. and how big of slugs and sleeves do i need to go to like 2.0 l
Thanks for the help guys, im kinda new to engine building and learning more as i go thanks to you guys

Yo Pete finally pullin that biznatch out eh. To answer some questions. Stock bore on our motors is 81mm which I believe is like 1795cc something close to that. If it was me and I was going to use stock sleeves and run more boost I would go with 9:1 pistons, but if you build the block with sleeves I would definitely do 10:1. If you sleeve it bigger 84mm you will make more power with displacement and less boost I believe than 81mm. The stock bore sleeved would be good too but if your gonna go all out why not go all out right Hope that answers some of your questions. Yo we are pullin the head on Sunday. We got a crew comin Josh, his boy, Tim, and me so hopefully we can get my car backup and running.

all the B series have 81mm bores from the factory cept for the B20. you could go with 81.25mm using the stock sleeves, and just do rods/pistons/fasteners. or you could go with the sleeves, bored to any size between 81-84mm. but you'll need the pistons to match the bore, and if you use an 82-83.5mm bore you'll need custom pistons to match. the 81.25, 81.5 and 84mm sizes are the common sizes you can. running 84mm bore on the ITR block will yield close to 2.0L, but i bit less. and you can still run high boost on most sleeves, though it can vary from brand to brand and the style such as closed deck and open deck.

i've looked at the Darton sleeves that you mentioned were for sale for $425 in the Classifieds. they look like good sleeves just be sure of what you're getting before picking them up, make sure they will fit your block and work the way you want.

i have a set of brand new Ross racing pistons in 84mm bore size that i need to get rid of soon. i think they were close to $600, but i don't need them any more cause i got a set of 81mm. they yield about 10.6:1 in your B18C5 with an 84mm bore, which is almost perfect if you ask me. i was only asking $500 for the set which includes rings, pins, locks and a spec sheet.

Stock bore on all b-series motors is 81mm.

If you are going to go with a bigger bore do yourself a favor and go 84mm so you wont have to make custom pistons. Most companies make shelf pistons for 84mm block.

If you are going to sleeve the motor then go either 81mm or 84mm just to save yourself the headache of trying to find custom pistons.

Bigger bore = more displacement which in turn equals more power and torque.

Wo-Nelly

Just a word of warning, if you do max out the bore at 84mm, and something wrong happeneds, you won't be able to bore it out again. You'll have to replace the sleeves again. But say if you bored it out to 82mm, some wrong happeneds, you can buy 83mm pistons have you block bored out to 83mm and your done, no resleeving. Just something to think about

boosted hybrid

Go 84mm. On Darton sleeves, you cannot go larger than 84mm with boost. On GE you can go 85mm. Leave yourself at least .5mm overbore incase you crap a piston.

85mm on darton sleeves with boost shouldn't be a problem....

i2un

I'm also thinking about sleeving. I may do a 83mm bore. The only downsides I found are:

1. Big bore honda engines have been known to blow head gaskets.
2. Piston slap doesn't sound as pleasant as a stock motor.
3. You don't have to do it...but if you wanted to match the head to the bore of the block it's extra money.

PS.
Please add to my list people if I'm not mentioning something.

damn , guess i got some thinking to do . Jeff how long does GE take to do blocks ?I dont want to have it out too long.
I dunno what i wanna do , someone else mentioned the if something happens i have no room to bore more . . that would suck

boostaholic

On iron sleeved blocks, i think an 83mm bore is the perfect bore size to go with. You pick up a little bit more displacement, still have a nice thick sleeve, and can get off the shelf pistons.

boosted hybrid

GE claims 4-6 weeks, but they usually take longer. Your best bet if you want to go with GE is to find someone selling their sleeved block.

PM-Performance

you got any laying around , i know your a conesour
i dunno , i guess ill just relax for a while and do some more research .
how much does Darton charge for Sleeves brand new ?

boosted hybrid

I do have a GE block but its 86mm and 13.5:1 compression. Somehow I dont think it would work out to well.

PM-Performance

hahaah with you tuning . . i think it can work.

yeah, going with say an 84mm bore size and then marring the cylinder walls or something means you'll need to go with an 84.5mm bore size. if you're using the Darton sleeves and they recommend no larger than 84mm with turbo, then i guess you're gonna need new sleeves. but with the GE's you can go 84mm to start, then still go to 84.5 and 85mm if need be.

or you could go the 82 or 83mm route, that way you'd have much more room to play with in the future. but i know you want to go 84mm so you can buy my 84mm Ross pistons.

or you could buy Jeff's N/A block and run about 18 lbs. on that. it should work out fine.

Why not go through me for Darton. Im local so no shipping charges for you. Also turnaround will be about 7-10 days max.
PM me. I can sell you the whole setup and assemble it too if your interested.

the way i see it, go 84mm, if you fawk up you still have 84.5 and 85mm to go to. if you fawk up more than that, you shouldnt have a car...enough said ;p. but honestly, you do have flexibility w/ 84mm sleeves and bore. if i was you pete, i would buy another block , get it sleeved, and work on that one while you still keep the stocker in teh car. theres so many variables that can happen to delay your project..its just not worth takin out your sole block and sending it across the US if your in a hurry. im using 84mm 10:1 ross' , they are great pistons and the guys are very easy to work with. i would go w/ ge sleeves, vince is a standup guy, you wont go wrong.

93LSivic

Yeah, but you can run 84mm Dartons and fug up a cylinder....simply fixed by dropping in another darton sleeve, bore and hone and your ready to go again.

PM-Performance

I got a quote from one of my sponsors to do dartons and installed for $700, can you beat that?
pm me pricing on just the sleeves them selves and then instlalled too .

damn....i just got my block resleeved with darton sleeves and its bored out to 84.5mm. you wont be able to boost it? man im getting scared, i just spent a lot of money getting all my **** built back together. i hope my setup works out because i cannot afford another engine rebuild. i'll let you guys know how well it works out, we are putting the engine in this weekend.

PM-Performance

does anyone know where to get valid part number for JE or sowemthing
i decided to go JE 84.5mm , in either 9.8 or 10:1. are these custom or what becuase i cant find any bigger thna standard bore on any sites . . . unless im retarded i dunno /

soundman

Could you bore out your block to B20 sive and use B20 pistons?
