I'm doing a B20vtec turbo build, and was looking into sleeving, when I noticed that a Dart block is only about 500 or so more, as sleeving I found costs 1500. Anyway what do you guys say Dart or Sleeve the stock Honda block? U guys got any forums that have the benefits of a Dart listed? Thier website doesnt have that much info, thanks in advance guys.

never a good idea to sleeve a b20, dart has a good rep.

Dart makes a good block but personally I'd rather sleeve an OEM block.. Some companies prefer not to sleeve the b20. I know GE will do it and I think Darton but I'm not certain.. I'd just pick up an LS block and sleeve it..

The Dart block needs a lot of work before you can use it. I would personally get either

the tall deck dart block and spend the money to make it right or get the oem block sleeved

by a shop that has experience with Honda blocks.

tadaow? because b20's are prone to leeks when there sleeved because the 2 center cyl. are conjoined, also sleeving is way to expensive especially compared to the quality of a dart block

are you sure? it takes a lot of work to get a dart block ready to use.

a b20 block is the same as LS once its sleeved (LS block after 96)

Price of sleeving block depending on where ranges from $900 to $1350. The cold of a Dart

block ranges from $1500 and up depending on where you buy it from. Then you have to weld

up certain places on the deck and have it shaved flat and you have to de-burr the casting

marks on the inside of it. They are (from what I hear) stronger than a sleeved oem block.

true but dart blocks are also closed deck so that alone is a pluse for turbo over sleeves, they have strengthened main webs, dry sleeved cyl. steel caps etc. so even after you sleeve an oem block you're still vulnerable to wear in other areas of the block

Yeah i really don't know, I mean I really like the idea of the dart block but how bad is the process to get it to work? Is it something that can be done in house in a normal shop, or is it expensive machine work?

dc2_dustin!

you can do it at home if you have the proper tools, i would never sleeve and especially a b20

endyn sell the dart and does all the machine work needed including welding the deck...but the dart you cant o-ring like an oem block...if ur going for higher than 800...mines was stepped deck..hopefully the headgasket will still seal...for the power i want..

Dart Blocks are very well engineered but we are talking about spending 1500+ on a bare block vs Sleeving a B18 is about a a grand, no more than that. That still leaves you room to get all tha machine work needed to put it all together and maybe still buy a ITR oil pump and waterpump!!! Again TADAOW for Sleeves in my book!!!

dc2_dustin!

yes that's true but as i earlier stated there's other advantages to the dart block mainly being the overall strength and closed deck which i believe the op stated was running boost and the closed deck is a way better desgn to support that

hybrdthry911

the most powerful b series in the world aren't running dart blocks. seems like sleeved honda blocks are more than strong enough.

0bd1_Kanobe

X2 if your a baller then even I would get a Dart Block!! But thats not the case here, for the money you just cant beat a sleeved honda block period!!!!!!! Again tha Dart block is stronger in desinged closed deck block but to me thats no worth forking out an extra 500 dollars !!!!!!!!

If your worried about sleeving an OEM honda block then buy a GSR

block. It has all the webbing for handle high RPM's, internal oil line

for vtec, and has a girdle on the mains. The Dart block is a very nice

motor and will last a very long time when done right. Just look up

on ENDYN's website and see what they go through to make them

"right". The closed deck does give more strenth but guess what?

Darton sleeves close the deck as do AEBS. Plus on the Dart block the

cylinder liners are thin and aren't as "beefy" as the fore mentioned

sleeve options. IMO if I am buying an aftermarket block it better be

ready to roll when I buy it!

that's not true..sleeving a block does not make it a closed deck, and the sleeves may not be as thick but there alot stronger

cibao2ner

when i receive my dart back they told me how good and how true the block is after machining...the close deck allows for better ring seal than the sleeved block cause the sleeves stay round from top to bottom...also with the billet mains and thicker aluminum webbing the block supports the crank... not the other way around like on oem blocks...after all the headaches ive seen people having with sinking sleeves and old blocks that need inserts cause they were over torqued...i think the dart is a good deal..but youo can buy a built block for 3500..my dart ran me 2300 from endyn with debured,welded deck and clean up..100 for crank..550 for cp pistons 100 for upgraded pins, 750 for manleys and 320 for +625 bolts..350 moroso pan...1500 for assembly and machining..deck plate bored and honed, align hone, stepped deck, bearings and trust washers...for a total of 5900...ive seen a ton of built sleeve blocks go for half of that..on ebay and here on the classifieds...any questions pm me...also block is built to handle 1200hp+

I haven't read up on the Dart blocks in several years, but weren't they banned by the NHRA about a year after they first came out? Thus you may not see them in "official" engines that have lots of sponsorship and funding behind them?

The tall deck always intrigued me as that was one of the big things that held people back from stroking. Back in the early 2000's there were some shops that would weld a 1" or so piece to the top of the deck and resleeve with longer sleeves, but the dart was formed all at the same time so the fear of someone welding your engine wasn't there.

I love the dart blocks. They are the best block if you have the money. Just for the average

or above average racer they don't justify using them due to price and the fact that they

almost always part out their cars or flat out sell them. If I had the money and didn't want to

race sfwd I would get the Endyn tall deck option. Has anyone tested that 1200hp rating? I

would love to know if they can really handle it.

how bad are sleeved blocks for the sleeves dropping? is it common?

Not anymore, its very unlikely. Sleeving companies have learned from their mistakes..
