Over the winter I am going to do a build up of my d16y7 so she can handle more boost. I am going to be using a greddy turbo kit and was wondering if I could get away with just rods/pistons or should I get sleeves as well if I want to run 15psi on the greddy kit. Tuning done with hondata s100b. Thanks

 

my personal opinion would be to sleeve it. 15lbs has been done before but i would NEVER trust a stock sleeve honda engine on 15 lbs.

once again, thats my opinion.

 

Been boosting D16 for more than 5 years, never cracked a sleeve. For the past 4 years, I never boosted below 14psi, now boosting 18-19 psi and no problem. I even boosted 25psi (wasn't suppose to happen) on a 5sec run and it handle it. Sure a sleeved block would be stronger but until I feel the need, I'm staying with the stock sleeve.

 

Any other opinions?

 

no u wont need a sleeved block

 

My opinion based on other peoples setups is, you won't need to, but it'll probably be a good idea. So depending on how much you care right now about that motor staying good, strong, reliable, and how much cash you have, make up your mind. It could go either way. But i'm not going to garuntee it at 15lbs, its just one of those, theres a descent chance you'll be alright. I've seen people run 25lbs on b-stock b-series sleeves... we'll see long they last.

 

IMO, sleeving a d-series is a dumb idea. for the money, you could drop in a b16 or an ls with some parts...

 

ide just put in a blockguard...check out st00pid's thread on this page...the setup he did looks like it works good

 

15psi on a small greddy turbo will make alot less power than 15psi on a t3/t4, 15psi on a greddy should put you @~230-250whp, IMO you do not need a sleeved block for this, stock sleeves should not have a problem handling that, especially with good tuning.

 

if you dont sleeve it, your cylinder walls will crack at 1psi.

 

you don't have to sleeve...just spend about $100 on a block guard and boost up to 30psi if you want...but on a y7...don't go past 15...its risky but its not impossible...but not safe either...now if you had a b series its a more performance block and you can go 30psi with proper tunning and not crack those sleeves...many people have ran these numbers even on stock internals with no porblems... http://www.inlinepro.com is one proof..good luck and remember a b series is much stronger than a D...so be careful....get a blockguard at least...

 

I'd like to hear more opinions on blockguard as I have heard mixed opinions on it

as long as its installed right they serve there purpose well

 

why spend 900 dollars on sleeves when you can just find another d series block for like 50 bucks if it breaks

 

just use a block gaurd. that's what i'm using on my current block and i'm running 15psi right now making 276.9whp and 252.2 wtq. planning to run more boost soon as soon as i can figure out if my rings are going out or not. make sure (and i'm sure you've heard this a million times) you bore and hone the cylinders after the installation of the block gaurd. also, making sure the holes line on the bg lines up with the ones on the headgasket.
