b18b at 81.5mm, 400whp

[slambed_civic]

right dickweed. reading owns you because if youd read anything about blockguards and do some research on what it takes to get 400whp out of a stock sleeved b18 you would find that they are junk. so i will let you read on your own to find out why they will do more harm than good, not to mention they ARE NOT needed. heres a tip, go to evans-tuning.com and look around there.

as for the pistons, i dont care what he has, obviously his old ones are not going to fit. what i was saying is to use 81.5mm bore and pistons. period.

get your learn on young grasshopper

dude, who pissed in your cheerios this morning?
first off, reading has owned you once again, not once did i mention anything negative about block gaurds. i asked a simple question as to why you said "screw blockgaurds"

secondly, you told this dude to get a new block bore it to 81.5 and put his pistons and rods in it. again, if you read anything before opening your pie hole youde know that his pistons are already too small since they are stock bore.

 

[stealthy]

wow. get over me using the word "his". again, hes not putting your pistons or my pistons in, obviously they are his. yes, he has to get new ones. I KNOW HIS PISTONS ARE TOO SMALL!

anyway, reading has not owned me once, nor twice. i also never said that you claimed anything negative or positive for that matter about block guards. i answered your simple question with the answer of you reading for yourself why block guards are unnecessary in a 400whp b18 with stock sleeves.

you still have yet to give a reason as to why they arent any good. just because jeff evans says that you can run stock sleeves for a 400whp car doesnt mean that this dude cant use a block gaurd. you are seriously way too hot headed. i asked a question and you flew off the handle. calm down. im not here to flip on people or tell them they are wrong, unless they actually are. im here to learn. so take whatevers in your ass out, and just chill.

 

[jason_guy_yeah]

hmm...interesting but, I can't use the 81.5mm bore since the cylinders are scored. And I take it 82mm bored stock sleeves won't like 400whp (boosted). So, well I have to get a new block? But, having a b18a/b; will I have oiling issues/pistons getting too hot at this hp goal?

no, you should be just fine. those oil squirters are there to mainly cool the piston and lube the wrist pin a lil more.

So, I'm ok at 82mm bore and 400whp goal at 7k rpms? correct?

sure? itll run, but for how long? i cant answer that. but truthfully, its a risk that i would not take. just find another block and do it the right way

 

[jason_guy_yeah]

Alright awsome, I'll go get another block, have it honed (81.5 or less mm then boost).

send it to the machine shop with the pistons that youde like to use with the specs as well, that way they can get your piston to wall clearance correct. you doing LS/vtec?

Nah, I could pick up a gsr head for 400 but, I don't want to move the rpms above 7k without a crank girdle or oil squirters. And I already have a b18b head with double valve springs although the extra head flow would be nice.

youre already getting rods and pistons. itll be fine

 

[jason_guy_yeah]

well, from what I've read, I might be able to push it to 8k at most (built ls/vtec)

you can go 9

like i said. search. quickly put, you will have cooling issues and it can also cause the sleeves to egg shape bc it only supports the top of the sleeves. its been proven time and time again that with proper tuning you can run 400whp safely with stock b series sleeves, so why f**k with it?

which is why i said get a new block, bore it to 81.5mm and you will be perfectly fine with proper tuning.

 

[mike@synapse]

i dont know what is going on with all the myths about these ls vtec stuff.

a crank girdle is not necessary for an LS block to spin over 8k, i would have no problem spinning 9k. oil squirters are not necessary for forged pistons, and are often plugged anyway. the ls crank cant even fit without bending or plugging the squirters in GSR block. sure a gsr/itr block would be the ideal choice for added stability but if an ls block is all you have run it you wont have any issues.

81.5mm no block gaurd is how we build our stock sleeved motors, and have never had a sleeve failure at 400-500+whp. get a set of 81.5mm cp/wiseco/je pistons and have a machine shop bore and hone another block to piston spec.

dont get an aftermarket girdle installed either. just get a gsr one if you are dead set on it.

okay. 400hp is available with stock sleeves without a blockgaurd. there is no arguement on my part there. knowing that my stock FLOATING sleeves will not be moving under higher boost is just something that i like to know. its a measly 100 bucks for a blockgaurd.

now... onto the cooling issue. you say there will be cooling issues due to the restriction of flow from the blockgaurd being in place? the holes in the stock headgasket will restrict flow. so from what i gather from your words of ultimate wisdom, this should cause a cooling issue.... i think not.

this is my LS that i built a few years ago with a STR block gaurd.

this is a B16/GSR block with a gasket on it. see how small the holes are??

***my point here*** cooling should not be compromised by properly installing a block gaurd into your block. just make sure if you do it, do it before you send it to the machine shop to get bored/decked.

 

[jason_guy_yeah]

hmmm...good info

 

[slambed_civic]

just go LS/VTEC you wont regret it. then you can boost it

slambed_civic:

thanks for posting pictures of blocks, i must have missed what mine looked like when i built my own GSR with cp 9:1 81.5mm pistons with stock sleeves. i think i even threw a head gasket (cometic) on my motor too. so yeah, i know what it looks like.

granted i dont have any experience with a block guard, so i am obligated to fish through the internets cesspool of misinformation and track down the correct stuff. ive seen time and time again where motors with block guards had cooling issues, and with that said i would go out on a limb to ASSUME that these problems could have been avoided without the use of a block guard.

your theory, in part, sounds good and makes some sense....however, its not correct (the whole headgasket issue you speak of and thankfully posted pictures of).

maybe mike@synapse will chime in with why THEY dont use block guards on 81.5mm stock sleeve builds

btw, that looks like a stock head gasket in your pic, heres a Cometic. looks so holey in should go to church every sunday.

just rev to where every your power drops off. if you can make power to 9k then do it
