well i've come to the conclusion that my rex isn't that fast....well first of all the b20 bottom end is all stock...the head is built though.....i beat a lot of people and my 1/4 is 13.7 all motor 12.7 with a 70 dry shot....i was wondering if you guys would buy a b18c1 block and swap it out...its a b16 head that i'll put on the block

so basically what do people or you guys run with a gsr bottom and b16 head?? or just straight gsr??

thanks

 

Any rex runnign in the 12's and 13's is fast man.

 

thanks man....i picked up the GSR block anyways....im gonna try run it at the drags and see some times....if i dont like it, i'll put it up for sale

 

how much are u revving it up to and how much headwork is done?
u can just throw some pistons and rods and get the crank balance/polished and make big power, get mid-low 12s na in your crx

 

headwork is all done ....the only thing that could be missing is a p&p .... but there's always room for improvement in the cams department....anyway....im not gonna throw pistons and rods in the b20....if im gonna do that i might as well save and sleeve the gsr block and make it 84mm bore....

do you have a poor mans type r in your car? or a gsr?

 

ive got a b20 but its coming out for a b18c (jdm gsr) which i will eventually be boosting
also what yr/model rex u have?
a hf or dx of 88-89 should be able to do 12s with the gsr/b16 worked head combo too

 

What head is on the b20 ?

 

well im not sure if you're talking to me or him but im running a b16 head....ss valves, dual springs, retainers, itr intake manifold, ctr cams.....

my car is a 90' ...there something about the 88-89 crx that i dont like....no offence i love crx's but i donno...im really hard headed....oh well...i might pick up a 89 though....

 

the only bad thing is that you made the b16 head for ls/vtec, and its kinda hard to reverse it...

oooook.....for ls/vtec you have to plug one of the oil feeds and then tap for oil feed to the head....and what i was saying is that it is a bitch to reverse this...

 

k yeah that guys post didn't make sense....but why is it so hard? all i gotta do is unplug the hole and plug the other one....

 

i dont know what kit you have if you got the ge one then i think you it is ok to just unscrew it...when i had mine done i got it welded..

Your running a stock bottom b20 ? Did you do anything to the pistons, I'm surprised you did not smack a valve yet

 

yup completely stock bottom end....

oh i didn't get a kit. me and some friends did it ourselve....i think we used a 5/8 pipe thread bolt thing to plug the whole....
