k, well back to the b20. nuff said.

 

here is this

http://hybrid2.honda-perf.org/tech/b20/b20tech.html

there is another jdm b20z engine which has the 9.2:1 ratio

 

You can send PayPal to enigmagination@gmail.com anytime

 

the stock b17a1 compression ratio is 9.6:1 which is the same amount as what eek posted so really you dont have lower compression then the b20 you have the same amount.

ill still pay up just because i thought that the comp was 10 something but no paypal here, ill just pay up in person the next time im in NN.

edit- stock specs- 9.7:1 from www.g2ic.com
http://g2ic.com/specs.php


you can keep the 5 bucks and buy a haynes manual or something or just save it b/c it seems like you really need 5 bucks. i think that the compression ratio calculator only works if you know everything about the motor, ie deck height and everything else.

4real tho back to the b20.

 

If you run the numbers you'll see 9.54

I don't trust 2GIC.com anymore after I found some misleading information.. and the fact that the site doesn't have shit compared to some others.

 

sorry for jackin this thread, go for the b20 its a great motor and its going to be my next motor.

 

84 mm bore, 89 mm stroke.

The most available displacement on a Honda motor without working the block

 

I know that this horse has been beaten to hell and back, but for those of you who have the bible (Helms manual), it states on page 3-14 that the B18A1 compression is 9.2:1 and the B17A is 9.7:1.

As far as the original topic...Dave22 couldn't of said it better. The best thing to do is to swap to a vtec head.

 

or boost.

 

Or take the damn thing out and try another engine.
