Stock sleeves question...
 

So I've got a dilema...I could either a: get a new block, sleeve it and build the crap outa it...or b: I can get the sleeves in the y7 bored and honed, get pistons, rings and rods...basically rebuild the motor...and than I want to boost the sucker. I'm just shaky about running over 10psi on stock sleeves...overbored stock sleeves that is...

RE: Stock sleeves question...
 

Why are you shaky about running boost on stock sleeves, the last pinks episode with the fullrace civic had a built D16Z6 with stock sleeves posting 450+whp numbers. The whole "you gotta sleeve it" bs has been conjured up by the aftermarket. Unless you plan on running over 500whp on the street they are un-needed.

RE: Stock sleeves question...
 

WHat I'm saying is, there's almost 200K on the clock, the sleeves WILL be overbored...I just want around 250whp in the end of the project

RE: Stock sleeves question...
 

if you are going to bore it you might as well get good aftermarket sleeves. any idea who you're going to get the block done by?

honestly if you just want 250whp you dont need to bore/stroke it. the torque gain is mild. how much are you planning on boring it?

RE: Stock sleeves question...
 

I have to bore it because it's in absolutely horrible shape...I'll bore the least amount that I can

RE: Stock sleeves question...
 

I wouldn't think that for 250HP you would need new sleeves, but if you have the cash and your willing to spend it, it can't hurt. If anything you could run more boost and get even bigger gains. Either way you are gonna want to get forged pistons and rods so you can get to 250HP. I think that you should bore it b/c if you get new pistons, you will have to have the block machined anyway so you might as well get some torque gains while your at it.

RE: Stock sleeves question...
 

I want a car right now, and if I decide to put it off until I have enough to do it all at once I'l have to drive a 200K miled lx

RE: Stock sleeves question...
 

Man sleeves are not needed at all is what I am saying. overbore it if needed but I doubt it will need more than being honed. 250whp is nothing at all, that can, has, and will be in the future attained by stock blocked D series. The only thing I would worry about at those levels are the rods which if tuned correctly will not be a factor. You getting sleeves for 250whp is like me getting racing seats and a roll cage......total overkill.

I would not invest in sleeves unless it was a track only car or something I planned to make gobs of power with, like well over 500whp.

RE: Stock sleeves question...
 

So I'd be fine If I just did rods and pistons, and bored and honed the block? Any suggestions on the head side?

RE: Stock sleeves question...
 

Y7 head?

Really on the single cam's all you need to do is port/polish the exhaust ports, port the intake ports(do not ever polish the intake ports on a head) and get a cam for your application. The Y7 has no cam made for it but you can get delta to regrind a cam for you to what ever specs you need, on the Y8's and Z6's I advise a AKMEE Type S cam and head upgrade package.

got a link to akmee marty? you got me interested

RE: Stock sleeves question...
 

so switching to a y8 head would be better in terms of aftermarket available?



and is that cam good for turbo or n/a?

RE: Stock sleeves question...
 

no, that would just cause small problems because of it being obd2, where yours is obd1

RE: Stock sleeves question...
 

I thought all 96+ were OBD II

RE: Stock sleeves question...
 

my bad, your car is obd 2 you would want that a y8 head sorry.

RE: Stock sleeves question...
 

if u wanna save some money just have ur stock rods shot peened... i think most local shops can do it... but im not sure. can anyone verify this?

RE: Stock sleeves question...
 

I've heard the term, but what is it exactly?

RE: Stock sleeves question...
 

It is the same as over bore but to alot lesser extent. What it does is just takes off enough to smooth and level the cyl walls out. When to speak of overbore I thing .20 to .40 thousandths off which is a good amount but still not in need of sleeves for a 250whp level.

RE: Stock sleeves question...
 

What are you talking about Marty? You just lost me...I was asking what shot peening was...

RE: Stock sleeves question...
 

oh I thought you wanted to know what honing was lol. I dont know about what goes into shot peening as I would just assume use B18B rods vs modding a stock D series rod. But forged > both of them and hell what is $300 for something as major as rods.

RE: Stock sleeves question...
 

LOL....I know....I just thought that it could be something worth looking into. I'm not sure if just honing the sleeves will do the job in this old commuter...it's burning and leaking and all other nice stuff...

RE: Stock sleeves question...
 

shot peening is kinda like sand blasting but its done with small metal pellets (kinda like pellets in a bird shot shotgun shell...shot...shot peening...get it?). it densens the metal and removes seams taht are there from when the rods are made. it increces the strenght by three or four times and its really cheap if you remove the rods yourself...five or six bucks each rod last i heard. probably the best strength to price ratio you can get in the bottom end.

edit: k here are some pictures to illustrate cuz i know my descritptions kinda sucked

this is stock. the seams are hard to see but theyre there and they are the main weak point of most stock rods

ive pointed out where the seams are most obvious because theyre kinda hard to see.

this is stock but its shot peened. much stronger.

notice there arent any seams in it.

the site i found that on listed these as advantages to shot-peening:
[ul][*] Prevents fatigue failure in metal parts [*]Allows existing part designs to function at higher stress levels [*]Prevents stress corrosion cracking in metal parts and pressure vessels [*]Enhances lubricity on gear teeth and other bearing surfaces [*]Produces uniform textured surface finishes for special coatings adhesion and cosmetic requirements [*]Work hardens mating surfaces to prevent fretting and galling [*]Forming and straightening metal parts without inducing surface tensile stresses [*]Closes porosity in castings and powdered metal components
[/ul]

you can also do it to gears, cranks, ect to increase strength.

RE: Stock sleeves question...
 

hmmm...and should my local machine shop be able to do this?

RE: Stock sleeves question...
 

probably. most machining shops can. im pretty sure that if youg et it done you will be able to hit your goal of 250 without problem. and for 20 bucks plus the time it takes to pull out your bottom end, who can complain?

RE: Stock sleeves question...
 

I guess it's worth a try....that's 300 bucks spent on fuel management than:-D and if I blow it, than I blow it

RE: Stock sleeves question...
 

I noticed that you were inquiring about aftermarket connecting rods in another thread. I think that aftermarket rods come shot peened. You could still shot peen the crank.

RE: Stock sleeves question...
 

almost 100% of aftermarket rods are shot peened

RE: Stock sleeves question...
 

Z6 head with OBD 1 conversion, imo.

RE: Stock sleeves question...
 

yeah you will have way more tuning options instead of the obd2

RE: Stock sleeves question...
 

No need to do that all D series cranks are forged from the factory.
