b20 vtec top end problems
I recently built a b20vtec and slapped it into my 93 honda civic si. The bottom is balanced with 12.5-1 je pistons. The vtec head is a type r with b17 cams. The ecu is a Gsr obd1. I have only been pulling low 14's. There is all this hype about running in the 12's with a crvtec, but I think its a bunch of bull. Anybody out there know how to get my top end through puberty???

12's are possible with a good b20/vtec setup...what tranny, cams, tires are you using and how much does your car weigh with u in it ?

Re: b20 vtec top end problems (NA DC2)
Its all about tuning....The car might be running out of fuel up top.....You should put it on the dyno to see how's its doing. Also, as asked before, what tranny are you running?

SO!
its damn true.
but i was gonna say the b17 cams blow.
why did you take out the r cams?
you could shave down the valve recess' on the pistons and have more than enough clearance.

Try using some 10.0 compression pistons if you are running n/a. I'm not trying to be an A$$ but you should talk smack about a motor you didn't built right.....

Re: b20 vtec top end problems (Dragger817)
doing a motor swap with limited knowledge/experience and going to the track occasionally usually means your gonna have some problems. going to the dyno will be the easiest way to figure out your problems. new cams would help. could be anything. air/fuel, spark, timing.........who knows. but running 12's with a crvtec being bullshit is rediculous. as far as i'm concerned you should be running 12's with street tires, a nice set of cams, and some tuning.
for example:
b20 block
11.5:1 pistons
rods
vtec head(your choice)
intake manifold(skunk2, type r, jg)
decent cam(type r, skunk2, toda, jun)
ecu reving to about 9000
springs/retainers/cam gears
intake, exhaust, header
afc, fuel pressure regulator
type r tranny, b16 tranny, gsr tranny
decent clutch
gets you 200+ hsp to the wheels, 150+ ft/lbs of torque
that means easy low 12's in a daily driven hatch with 22" slicks or easy high 12's with a decent tire or drag radial.
but, the car must be tuned and you must know how to drive alittle bit better than my grandmother.

Re: b20 vtec top end problems (jinxproof99)
I have decent knowledge of doing swaps. This is the second motor I have built and it just seems that the top end just doesnt pull as hard as it should. I hooked up my friends skunk2 ecu and all I did was detonate. It could be something as simple as needing new spark plugs. Who knows. I was told I need to run my b16 ecu for the type r head and get a VAFC to turn up the fuel after 5000rpms. Maybe I will take a trip to Seattle to Dyno it.

Re: b20 vtec top end problems (jinxproof99)
dont listen to jinx jason, he thinks hes god cause everything he touches is fast. the motor is built right, it has small cams, tires r good, but top end isnt there. get the skunk2 cams and get to a dyno, thats the most important thing.

........and the kid did say... "There is all this hype about running in the 12's with a crvtec, but I think its a bunch of bull. " and i just thought that was retarded.

Re: b20 vtec top end problems (jinxproof99)
ur as bad as alot of other ppl. i know him personally, but u do in fact think everything should run 9s/10s turboed and 12s NA. u always talk about how ppl cant drive. ur ego is about as big as NY city but u get easily offended at the smallest comment. take a little of ur own **** and b a man. u drive a 10 second "daily driver" so u r THE MAN. i bet ur just a short little **** that weighs 120 lbs.
on a side note jason CAN DRIVE. he doesnt drive like ur grandma. his car is timed to 14 degrees to avoid detonation. he does his own work, therefor i would assume that his car is put together correctly (i verified when he was over 2 weeks ago). we just cant figure out his top end problem. runs good, good torque but lacking top end.

you don't know **** about me obviously. i get IM's daily regarding peoples set ups. i see people spend an incredible amount of money to go slow. then i see people have fast cars and they can't drive. then i see people spend 5 grand on a type r swap and go cheap on the install and can't figure out why they run 15's. not everyone has to have a fast car or has the money to spend on one. but don't come on here and say"crvtecs don't run 12's" then you back the guy. if you know him and like him thats fine. let him take alittle info/heat and thats it. so be it.
as for you, "hondaatwsu", you are a total moron. was it you who did the install?? i mean what is your problem?? is it that high elevation in seattle??? you don't know me at all. you've been a member for like 5 months and our paths have never crossed. how do you know what i think?? how do you know what kind of person i am?? did you even read my post??i practically built the ****** 215 hsp 160 ft/lb tq motor for you in my last post. theres no mystery behind it. seems to me that if you can't get a motor to work you should spend more time on the dyno/track and less time talking down to me(or anyone else on honda tech).
get a life ************.

Re: b20 vtec top end problems (jinxproof99)
im not hte one that built the motor. my motor is untuned turnin 13 flats all day long. the motor in question is my friends. like i said, 14 degrees to prevent detonation. we tried my skunk2 ECU, didnt work. tried 118 octane, didnt work. prolly needs bigger injectors.
ur right, i dont know u. i dont care to, i would say it to ur face if i was there. but my point is, u always talk down to ppl just like i talked down to u. i never backed him. i believe the potential is there for good times, just prolly not in his 2500lb SI. ive followed some posts of urs. therefor i came to my own conclusion. u get easily offended if anyone disagrees with u, or in this case, if i just tell jason to ignore ur comments.

well since i always talk down to people, no sense in stopping now. i've never followed a post by you, nor have i ever even heard of you till now. 13's flat all day blows. yeah, that ***** fine in seattle, but get real. go to any place with fast cars and you'll get smoked. and since i'm already talking down to you and yeah, your my bitch............tomorrow, when i'm at the dyno with my beater and the crvtec motor(that can't run 12's) and my top end is great and pulling well over 200 hsp to the wheels, you better believe i'll be thinking of you.
13's all day long.....get real.
and to that kid jason............if (hondaatwsu) had anything to do with your motor i'd think twice before going back. think about it. you have no top end and his car has thousands dumped into it and he still hasn't "tuned" it. makes me wonder..........

Re: b20 vtec top end problems (jinxproof99)
yeah i bet u will. 13s untuned on 45 series, not bad and especially NA anywhere around here.. yeah i guess everyone in VA must b way faster than everyone else in the country. considering that there is the "big names" in the import industry hailing from the great state u live in.

i'm sure when you attacked me you meant well, but give it up. i can be harsh sometimes but not this time. my original criticism was constructive and i wasn't out of line. i didn't say your friend drove like my grandmother, it was just a generalization. there could be one(or more)things wrong with your friends car, you just have to figure it out.
