How much boost can these sleeves hold relistically? I want to get forged pistons, rods, and a block guard and run like 9.5:1 C/R. With this setup how much boost can I run on my D16Y8? i mean I know with tuning and what not, but at this rate, i'll be running the the VAFC hack w/ the butt dyno most likely...

 

Stock sleeves are save to roughly 18psi using race gas & tuning(VAFC would not be ideal for this boost). I'd stick with some 9:1 pistons though as you'll be able to run slightly more boost.

 

I dont know man I think that you can run 18 w/o race gas. Look at turbo Panda with the supra pistons. HE ran like 18 daily er something like that with a block gaurd. Im sure you can just post your block and it would be pretty good. Oh yeah that did make the comp like @ 8:5:1 or 8:0:1 er something like that.

They have higher octane gas in thailand though.

 

They are made out of the same material as b-series sleeves as far as i know.

thats correct, just wondering how much boost they will hold. basically, I just want to have daily driver that not going to blow a motor and is a blast to drive with the custom turbo setup I'm going to put on it... I want to run like 11-12 lbs on AFC Hack, and maybe like 15-16 lbs on a Hondata setup in the future

I have done 16 psi on stock Y8 sleeves that were posted.

 

Since it's your daily driver forget about using the blockguard unless you want cooling problems. If your spending the money on rods/pistons you might as well do it right the first time and sleeve the block. Posting the block would be a cheap alternative until you can afford to sleeve the block.

 

sorry man, cooling issues with blockguards is a problem of the past...get with it

guys all I really want to know is how much boost with the stock sleeves take on an AFC hack? like 12 lbs or so?

 

PSI really doesnt mean sh*t. I've heard they are good up to 500hp though.

Was there a huge break through in blockguard design lately or something? Last time I checked they still sucked ***.

With proper tuning I think 12 pounds is fine. I plan on running 10-12 psi (200+ whp) with hondata on my stock D16Z6 here pretty soon. I will probably post the block eventually though just for added protection. Maybe also throw in some forged pistons and rods if I can find a good deal on some used ones.

dude, I know about 10 people with block guards in their daily drivers and none of them have problems with overheating at all. thats just a rumor. Posting is sweet too.

 

Block guards is how they are really designed is to be pounded in, then welded in, then have the block redecked, and rebored. Why? because pounding in a block guard distorts the sleeves, reduces cooling in the upper area of the sleeve (thus making it easier to detonate) more heat. I've seen tons of sleeves crack with block guards installed, they pretty much do nothing unless they are installed correctly. Your better off going half *** with some posts or sleeving it.

But all in all, tuning is always the key for a long living motor.

Let's see, what do I want touching my headgasket...a hot piece of metal or coolant? Hmmm

 

iam having problems with 8psi on d16z6 with vafc so i would suggest going straight to hondata if you can

 

I haven't had any problems with my AFC hack (safc) On 8 psi i made 176/173 with the APEXi kit. With my new turbo i'm gonna try and push 11 psi with a blockguard/arp studs/ headgasket and the 3 bar map sensor

There's a guy on the board that made 302 whp on 16.5 psi with just a headgasket and arp head studs.

No, that's bullshit. How is a light aluminum blockguard going to distort a sleeve that is partially made out of STEEL. It should be carefully tapped in. That is it.

Because it is forced into the gap between the block, and cylinder, it always distorts the sleeve,. Even if its a fraction of a millimeter, its still something that has to be corrected.

As for pounding them, your suppose to tig weld them in if you want to get technical.

If your in doubt, ask any machinest.

 

Machinest want to make money, don't ask them. I am telling you that aluminum WILL NOT distort steel even a fraction of a millimeter. If anything the blockguard would distort.

 

well if your so sure,, why don't you go measure before and after. you just might be surprised.

But what is the rating system??? In Japa their rating system works out so that their 91(I think, I checked on this like 6months ago) is equivilent to our 87.

Do you realize how small 0.001 of an inch is? A valve is steel, a piston is aluminum, and when the contact the valve bends, the piston is damaged too, but it doesn't mean the valve didn't bend.

I did. I tapped my GE block guard in. Piston to wall clearance was fine, no out of round. Everything was in spec.

 

I am not talking about piston to wall clearence. I am talking about the sleeve shifting.
