lets say for example u sleeve an 81 mm block to an 84 mm, and then wanna boost it. work with me here, im gonna try and draw it out...u have a certain amount before u max out the sleeve???so if u sleeve it to an 84mm (the sleeves get thinner the bigger you go), wouldn't this be just as risky as say boosting a stock 81mm????someone tried explaining this theory to me, kinda got it, but wondering if anyone can help clear up a bit more? preferably someone from golden eagle...

 

The difference is the material the sleeves are made of. I dont know the exact materials they are made of, but I do know the sleeves golden eagle, benson, erl, etc use have a greater strength......this is what the difference is between using a stock sleeve at 81mm vs a aftermarket sleeve at 84mm. I believe the aftermarket sleeves are ductile iron.

 

yea, but, im not sure, the way it was explained to me is, in order to press an 84mm sleeve into a block made for an 81mm, the sleeve becomes much thinner. it was explained, that basically any b series engine made to an 84mm is basically garbage??? personally, all i wanna do is safely boost a 2.0L, but if the risk is greater than the outcome, 1.8L boost will suit me just as well.

 

whos telling you all this stuff? I hope its not a machine shop.

 

Going with a 84mm bore is perfectly safe. Yes the sleeves will be thinner but because they are made out of iron they will be ALOT stronger then your stock 81mm sleeves even though they are not as thick. I think anything over 84.5mm or 85mm is the limit. Someone else can chime in that knows for sure. Tony1 said that he only uses 84mm bore in his motors. He also said that you have room to rebuild your engine and bore/hone your sleeves 2 times before they get to thin to where you would have to re sleeve it if you start out at 84mm.

 

The sleeves are not actually thinner... Inner diameter is 84mm, but on a resleeved motor, the entire outer diameter of the sleeve is made out of ductile iron, hence, thicker.

If you go 84mm on a stock sleeve Honda block, then yeah, that is basically garbage for boost because the iron portion of the sleeve becomes paper thin. The outer sleeve on a stock Honda block is basically a fragile aluminum casing.

 

what should i ask for? when i go to get my blcok sleeved. i have a 94 gsr block. i am using a gt37 or 40 r garret on 84 mm pistons build blcok cams the works tuned and lsd ect
are there any difference in the desings for sleeves im going for 700hp.
;thanks

if you ship your block to golden eagle they will use their own "made in house" sleeves which work fine.

if you take it to any other machine shop who has done that type of work before chances are they will use darton sleeves.

both are very good qualitly sleeves.

Let's not forget about the bracing that after-market sleeves offer. The bracing plays a huge role in the strength of the bottom end(obviously).

 

will i recieve my block? or a pre-sleeved block or core as they call it?

 

pretty damn sure a 84mm sleeved block still has thicker walls than an 81mm oem block... and again, material used, bracing etc... all play a major role.

That is something I am also interested in finding out... Cause I spent a good amount of time deburring it and smoothing out any imperfection. Also cleaned&slightly opened up any casting flaws in the oiling for the main's bearings.
My tuner got his block back from G eagle after sleeving and we don't know if it was throught the shipping process or what but by the time it got back the surface for the head had nasty scrape's, nick's and gouges on the edge near the oil passages.

 

i hope that doesnt happen to myblock.
i already payed to have it hottanked and i have recorded the serial numbers and such

goodluckm

OP, like some have posted before, a sleeved block is much better than a stock.
Differences are on the material and design.

It all depends if you want to buy a core block or send in yours. Golden Eagle has a sale on their LS core blocks right now, do a search on here and it should show up.

I've sent my blocks to GE and have received all of them back, so yes, they send you what you sent them. Unless your buying a core. Like you I always write down my block information, before I sent them in, Just a habit.
