You apparently don't know too much because a b20 doesn't have "thinner" sleeves compared to other B series. The material is the same, the thickness is the same, the difference is how the sleeves of a b20 are installed from the get go. the b20 has a 1 piece sleeve design compared to other B series having a single sleeve design. Also most companies that sleeve motors would prefer you to send in a b18 block compared to to a b20, just a heads up
As for b20's handling boost, yes they do. Search Honda-Tech for turbo b20 or boosted b20 setups, there is a huge thread on there of nothing but turbo b20's
Also my DD b20t made 302/256 on 13lbs and motor is still running 3-4 years later in another chassis.

its seems like you need something for DD and it also seems like you have money for a turbo kit too so i would suggest for you to just save your money until you can buy a b18c1,c5, or whatever NA you decide on because doing a mild built engine and buying a turbo kit for the car, and getting a vtec head.....you are saving money by just getting a b18c1,c5,etc depending on how cheap your getting the parts for the build......just my .02 but if it was me i would save up for a b18c5 because it will be less work and headache for me:lol:

I was just conveying information I had gathered from another thread, info that was provided by other members, and even info from this thread from nicoalex2. From what I had heard, it was basically the B18 bored to a 2L. Thank you for correcting that...This forum is how I learn more, so no, I don't know a great deal about the B20 compared to the B18. As for a response to poordc2, I don't want a B18C because I just dont. And I only want it to DD if necessary, I just want it to be THAT reliable.
If the material and the thickness is the same, how does the 1 piece sleeve benefit the cylinder structurally? Just asking for informational use.

My post wasn't aimed towards you, more towards the other "gurus" posting up in this thread lol. The singluar sleeve construction is actually the "weak" spot of a B20. I have never personally seen a B20 block have any issues due to boost, I would venture to say that those who had issues with sleeve failure in a b20 were due to improper tuning.

Yes they are the same minus the bigger bore of the b20 and sleeve design like I already discussed. The reason they are unreliable in my opinion are because they are usually slapped together, untuned and have the brains beat out of them. No stock ECU will run a LS/vtec or b20vtec properly thus the reason a tune is required, the rod stroke ratio of the ls/b20 isn't the greatest, but can be compenstated by using arp bolts, which most people cheap out on and don't do.

Read this. After reading this, it changed my opinion on LS/VTEC stuff.

no not the same
B20 on a B16 head = Poor Mans Type R
B20 on a GSR head = CRVtec - same horse power as PMTR but a lot more Torque
LS/V good too
