I would buy a VTEC head for your B20 and not trade.

screw his b17. Why do you think he wants your b20? Because he will probably get a b16 head, smoke you with the b17 you have and call it a day. You should think like your friend, and keep what you got and build that motor.

 

keep your motor...buy the head from your friend....then he wont have a motor and youll smoke him all the time....

 

You people seem to have missed the most important part of this whole ordeal. the B20A is from an old school prelude and is absolutely worthless. Anyone offered a B17 for one should not think twice about it.

If you decide not to trade, tell him I'll give him two B20A's for it.

True

my feet &gt; b20as

 

why is the b20a so bad, just wondering

 

no vtec

 

<TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote, originally posted by tekneshum &raquo;</TD></TR><TR><TD CLASS="quote">no vtec</TD></TR></TABLE>

no...

search for b20a and read about it...

from like 10 mins of reading, the b20a block will NOT accept a bseries vtec head, and due to its large stroke, has a terrible r/s ratio and cannot be safely revved high.

but the crank can be used as an oem stroker in a b18a or b, using the same rods/pistons...

but im not 100% sure about anything i just said so correct me if im wrong, or do you own research to prove me wrong...

I disagree.

B20A &gt; B21A

no its just a poorly designed b-series....alot of the parts are not interchangable....they mount like a h and a f series..they have the (ahhh forgot the name) sleeves that wear rings out fast. just because a engine doent have vtec...doesnt mean its bad. BTW trade it for the b17..its a good motor....also rare. id love to get one if i could

just go buy a b16 they are pretty much the same thing, same hp and tq numbers</TD></TR></TABLE>

117 lb ft. &gt; 111 lb ft.

only the b16b can match the b17s 117 ft lbs of torque.

 

til ur friend ill buy his b17a long block .. leave me ur # or ur friends #

 

even if it was a crv b20 id pic the b17

Amen.

Then I'd find a B16 shortblock, and use the B17 rotating assembly and head with the PR3 pistons in the B16 block with some CTR cams and an ITR intake manifold. Throw on a good header and you'll have one hell of a sleeper.

 

Yeah get that B17 and ditch the B20. CRVTEC AKA b20 w/vtec are not dependable set ups because the B20 blocks cannot revv as high and have a horrible rod to stroke ratio not to mention have very weak cylinder walls. Like most everyone on here's been saying the B17's are hella rare and are very desired, go with that set up, just put some ITR pistons in if you get a chance to up the compression.

pretty sure you have to mod it somehow. i read once they use b18c cranks to make more reliable when reving high and making good hp. they were modifying either the crank or mains, i forget which.

false, i brought my b20vtec to 9000 rpm all day long

 

Actually, its quite true that the casting process weakened the cylinder walls between cylinders in most B20 blocks. It was luck that you were able to bring a B20VTEC to 9000 more than maybe a few times without the rod bolts being destroyed and a piston or two flying through the engine or grinding down the cylinder wall because of the lack of oil in a stock non-VTEC car's design.


There's a reason why Honda designed VTEC engines with oil squirters. It was to keep piston temperatures down and to keep the cylinder walls well lubricated. Also, VTEC engines require more oil than non-VTEC engines. There's much more to building a reliable engine than slapping a VTEC head on a B18/20 or H23 and calling it a day while revving way past the designed redline.
