I'm getting ready to start building a block, and I'm pretty sure I want to get Benson sleeves. I would like to get into the 300whp area with my current turbo (T3 .60trim) and later after I get a bigger turbo, into the 400whp area. Some people say that the stock sleeves are good for around 400whp. However, I would tend to stay on the side of caution, and i would much rather do it the right way the first time. Does this sound like a good idea to go ahead and sleeve it given my horsepower goals?

I'm guessing you haven't done anything to the block yet? Your running bone stock on everything, correct?
Well your gonna wanna completely build up the block if you wanna run a D-series motor into the 400whp range, it would be cheaper to do it to a D than to a B but your gonna be at risk for the longevity of the motors life. The stock pistons, or actually the bearings are one of the weaker parts that I have run across, you should buy a block off ebay or a junk yard and build it up slowly if you can, it would be easier to do it that way then to do it to your current cars motor.
The stock motor is good to about 175whp or so, depending on the motor, I've taken D's upto 200whp before they blew up. But if you wanna run for any length of time, your gonna wanna completely rebuild the motor. Also your gonna have to get a crank made, as they can only handle about 250whp.
For more D-series info check out: http://www.d-series.org they have all the info that your ever need on your motor and how to boost it properly.

I'm not new to the "pushing the D to it's limits" world. My Z6 is currently pushing over 200whp on a completely stock longblock. And it's been doing so for over 20k miles. One of my friends is currently running over 400whp on his D. I was just trying to get other opinions on sleeving it.

not true. I've been doing more than that for over 20k miles, and there was a guy who got his stock block turbo z6 into the 12's.

My bet is on bad tuning. Stock internals can handle about 230whp with an excellent tune.

I've never heard that before. Moreover, any crank is incredibly strong, and capable of holding more than 250whp. My friend with an over 400whp D-series is using a stock block. Why? Because Honda knows what they're doing when they engineer parts. OEM is the way to go.

anyone?

Sounds like you are on the right track...

If you have the funds to sleeve, I would do it... your engine is going to be that much stronger...

You could probably hit those numbers with stock sleeves but it won't be as safe... but you probably already knew that...

I'd sleeve my block if I had the cash... baller style

Good idea? Yes, do it. I would get another block though and build that up as previously mentioned so you can still drive your car. Who's the other company that makes sleaves? Dart or something? I can't quite remember. Anyway they will install it for you for something like $300 or $500 + price of the sleeves. This is not really something you can do yourself unless your and experienced machinist.
Uhh I can't remember anything.. Im worthless.


Have a friend who has 220whp on a D16a6, stock internals. Still running great.

You're thinking of Darton.

How much do sleeves + install cost?

Soccerking3000

1000ish

Block guard it is.

Soccerking3000

as i told you in pm's the block guard is essential a poor mans sleeving, if done properly it can help out a ton and since the stock sleeves are good to around 400whp you will signifactly reduce the risk of cracks warpage et cetera with even a block guard, but its gotta be installed correctly

Not just me tapping it in. I've also heard of shops welding it in place. Good or bad?

Soccerking3000

you dont have them welded in but it is a good idea, if you tap it in get the block honed after to make sure it didnt warp the sleeves.
