Anyone have b20 bottomend in a itr?

 

Do you mean a B20 bottom end with an ITR head?

 

correct

 

what do u want to know?

 

I want to know if type r head, with endyn 11.1 pistons, ls rods (or some other ones), and whatever is need will preform alot better then my bottom end... is 200whp possible?

 

200whp is easy either way you go.
Both require the same amount of work, actually the b20 will require more money
and work but will end up with more torque IF DONE CORRECTLY.

 

Could you please elaborate a bit more on the subject Steve?

 

hehe,. i cant tell if this is a serious request

b20 has more displacement, and will yield more torque output.

 

No...I'm serious here. He said, "IF DONE CORRECTLY". I'd like to know a bit more about it. I would never tear my B18C5 apart unless I had good reason too, but my B18C1 is due for a rebuild someday soon.

 

would b20 bottom end, with lower compressoin + turbo at low boost

 

Local people have both setups done...

B20 + boost -> 12 sec ride in an EG
B20vtec -> wasn't so successful... never ran very good. (prob due to the build up).

If you want first hand experience on B20vtec, look up NAB20C5 and e-mail him.

 

my friends can build a hella hella good b20vtec, im just trying to decide if boost is worth it

 

Sean, correct me if I'm wrong, but isn't Eric's setup a bored B18C5 block and not the B20 Block? I'm assuming when you go this route you don't have to spend that much on the bottom end to handle the high revving since the block is just a Type R block bored out. But with the B20 you would have to build it up to specs so it can rev like a B18C5 block. I have been wrong before, please feel free to correct.

 

The stock bottom end is not meant to rev past 7500. You have to beef it up with rods and pistons (the stock compression is like 9:1), you'll want to put a GSR or z10 girdle for the crank. Put in machine shop time and labor and whatever else I forgot to mention.. Figure on spending over 2k including finding a block.. Not cheap..

 

from what im told, blue pritning and balanceing will make it able to rev, and some "street driven underground preformance sercets"

I would contact Import Builders. Those blocks weren't meant to rev to 9k. Built properly with internals, pistons, rods, bearings, etc. should make good reliable power with TORQUE..

 

You can get some good info on this at http://www.crvtec.com

 

dude, with most of ppl with b20 bottom end,and with b16 head i have seen can push to 230+ "at least".

 

o yea "dude" like who? I've only seen fully built race motors push those numbers..

Please enlighten us with your wisdom, dude.

 

would a itr head be good for the b20 bottom?

 

Do you have an ITR head on you? If not I would suggest you just build up the head as you would the bottom end. the ITR head is pretty much a b16 with p&p from the factory so you can save some money and get a b16 head then build up with that. I am currently gathering up parts for my b20/vtec so that import builders can assemble everything for me. All I can say is that the b20/vtec project costs a lot more than I figured. All I need to find now is my tranny and I should be about 85% complete. Think everything out first before you end up with no money and a half completed project.

has anyone had any experience with Exospeed's blocks?

 

i got this from crvtec.com:

Can I just resleeve a B18c or B18c5 block to 84 mm?

If you’re going to go as radical as ductile iron sleeves, we'd just stay with a B18c5 or B18c block. The reason we like the B20b/z blocks is for the special sleeves they have that allow the bore to get safely up to 84mm. So if you're inserting those in the block just save yourself: the price of the block, and work by not having to externally route the oil line for the Vtec head. One thing to remember is that the cylinder walls of the B20b/z blocks are thicker than the all the other B series blocks. So you might have a 84 mm B18c5 block with super-double-wack sleeves but it’s not the equivalent of a B20b/z block with its thicker walls and the same sleeves.

 

translate that for me
