This is more of a question to steve but if anyone else has input i would appreciate it. I was wondering what parts i would need to turn a B18B1 into a B20? I know id need to have the sleeves bored to 84.5 and get the pistons but what else is different between the 2 engines? are the heads the same, crank? rods?

Just looking for a little info on a side project im looking at doing for my "beater"

well the b18b and b20b use the same crank, rods, head.
And you can't just bore the engine to 84.5mm from 81mm you would have to get 84.5mm sleeves put in. It would be more practical to just get a b20.

damn, i thought u could bore the stock sleeves to 84.5? Basically i have a spare B18b1 but im not sure of the condition of the inside so i was thinking of doign a small inexpensive project to make it a or rebuild the motor into a fresh B18b1

if it's for a beater, just pick up a B20 shortblock and swap it in. no use wasting time and money turning a B18 into a B20 when a perfectly good B20 is available right from Honda

well i have a B18b1 sitting in the back of my hatch right now and im not sure what kinda condition it is in internally so i figured if im gonna open her up i might aswell get a 2.0L?

IF i was to rebuild the motor to a B18b1 i would have to get the block bored to 81.5 and get oversized pistons or rings correct?

oh you have a SPARE B18... then just forged rods and pistons, and blast that bitch with 18 psi

scarlemthug

yup i got a spare B18b1, damn that shiets heavy but my hatch looks perfect in the rear now lol.

im pretty sure the engine was raped but im not sure how bad the condition on it is . I wanna use my good B18b1 for turbo and use this one for my hatch. Although I could do that B.......hmmmmmmmm the only thing is i have the clutch and flywheel already on the EG.

got any spare y8 in that hatch of yours?.... check under your spare B18 LOL

scarlemthug

i got a spare tire under the spare B18b1

I couldnt say no to a $5 engine:P

imported_trackhack

I have a spare Y8 in pieces with a spun rod bearing...haha

scarlemthug

yeah steve i may go with a 2.0L but at the very least im gonna wanna rebuild the engine and put it in my eg hatch. It is actually a B18A1 so its an older motor but it doesnt look too bad yet. What would be the best way to get an idea of how the engine is as far as condition internally?

Im thinking this

B18B1 into 98 Coupe turbo (forged pistons, rods etc later on)

B18A1 into 92 hatch (rebuild the motor to a 2.0L or overbore to 81.5 ?)

hey don't your remember the "stay silent on the price or a cut your ***** off" contact you signed?

he bought the engine off me for 5 bucks. How did I aquire the engine? I helped a shop move locations and was given it because they sold their project car too me. I'm usingt he car for another use and the engine was free so I made 5 bucks off it.

Chris post up a picture of the broken part on the block to make sure Steve can fix it.

scarlemthug

yeah ill get some pictures once i get the engine inside my house lol, freakin i can lift it myself but getting it down the stairs is another story lol.

So the engine was in that multicolor snowbank of urs?

Thanks again for selling me hte engine Jay, even if the engine is completely useless fro some reason I can still tear her down and get the experience doing that.

How much are engine stands usually guys?

kwikb16a2

around 80 or so at princess auto....might be even cheaper

scarlemthug

ne one know anywhere cheaper to get one? Damn that thing is heavy, i just got it in the house now. Basically its the whole engine minus like distro, IM, exhaust manifold.

kwikb16a2

cheapest one at princess auto is $59

scarlemthug

not bad, its sitting in an 18inch tire right now. Not the ideal place to take apart an engine I dont think.

So what would you guys recommend I do. I wanna keep the project cost down so ill prolly look at either used parts or aftermarket replacement parts that are cheaper than buying oem ones.

So should I go with a simple 2.0L or just rebuild to basically stock B18A1 specs or maybe up the compression ratio with some pistons?

scarlemthug

Steve what would you recommend I do. I dont wanna spend huge amounts of cash on this as its for my beater car. Basically what i want is something thats quick, runs on 87 octane, something reliable with a good amount of torque like a stock B20 has. If you think i should sleeve the block and get some aftermarket pistons i might be willing to do that. But also im thinking maybe build the engine with all parts that i find awesome deals or that are "donated" to the project lol.
