i have a 91 civic si hatchback, fully gutted, it does have 4 wheel disc brakes, it has a b16 swap in it non lsd, intake, header, exhaust, full msd, i weigh a bit over 250, the best i can pull out at the track is a 15.6 at 88 mph, so i went with some lighter wheels these did weigh 20 poundds each and was having so bad wheel spin and pulled out another 15.6 at 93 mph, these heavy wheels made almost 6 miles an hour difference top end, if i was to run another 93 mph what kinda time should i expect and do you all think something is wrong.....i am a really decent driver, help, and other times would be a big help
 
do you have the JDM SIR trans? SI trans? or LS trans? either way you are running really slow sounds like driver error unless your running a crappy ass ECU?

my first time ever to the track with a FWD car a 95 coupe with system heavy wheels JDM B16 88-91 WITH LS TRANS!!!! and intake/cat back exhaust and the wrong ECU I ran a 15.2 could not run better but was right at 15.2s almost every run

what RPM are you launching at? I like to spin my tires just a tad bit hondas tend to take off better that way also if you want try shifting full throttle just hold down the throttle and when time comes to shift pop the clutch in and shift gears then let it back up

I was running 15.2s using normal shifting then I blew a start and shifted full throttle and still managed to run a 15.2 so it does help a good bit
 
I have a good j1 tranny and pr3 ecu (the good one), im launching at 5000 with the heavy wheels and jumping out the hole (really good launches) and I can drive pretty well, im not power shifting, but still theres some type of problem
 
20 lb rims??? what size are they???
 
That fucking blows, sorry if my english is a little shitty but I am drunk now.

Here we go, You have a 1.6m, cool. make sure you have a S1 tranny on that fucker if it's cable which you should have. I ran a 14.3 with a FIRST gen b16 stock oem longblock on street tires. Improve your skills driving. start at the tranny first.

20 lb 15s ?!?!?!?!?!?!?!?! :wtf:
thats heavy as fuck
drop some 10lb 15s on there with a better tire and youll shave a 1/2 second or more off your times instantly
 
still, 15.6 thats brutal, with a 93 mph trap time u should be around 14.6-7 or so. something has to be wrong, can u feel vtec engage? does everything run fine? try doing a full tuneup, cleaning ur engine out with an engine cleaner, advancing the timing. and retry it.
 
Put some lighter rims, 20lbs isn't light, that is heavy heavy heavy.

Get some light ass oem HX rims or some Kosei's, both are light and cheap.

im gonna get some lighter rims and i just did a tune up and when vtec kicks in it pulls really hard, ******* *with a 93 mph trap speed which i have run before shouldn't that get me in the high 14's ******
 
You should be running high 14's with that trap speed. I would like to know what your 60 ft time is? because you might not be getting of the line that well i run 14.7's in my 91 civic dx sedan with b16 and my trap speed ranges from 90-94 mph
 
Where are you running? If you are at serious altitude that time is not bad, it could be faster but it is a good starting point. At sea level that time sucks.
 
Even at 250 a trap speed of 93 should be around a second faster than he is running. I see cars make it into the 14's at around 89 plus all the time in VA.

Peace*
 
well guys, i just checked my compression, and cylinders
1,2,3 have 195-200psi, and cylinder 4 has 35 psi, and im still running 15.6's thats pretty good........so it's a 3 cylinder b16.....isnt that funny...
so now it LS/VTEC TIME....................i guess it wasn't the rims, or me being fat or my driving skills..........but thanks for you guys help
 
LS/VTEC won't help if one of the cylinders is still jacked up. Your using the same head for LS/VTEC, right? Why not just get a valve job? Take off the head yourself, send it to a shop, it'll run about $120.
 
lol, about the whole weight issue.. I used to be about 220, but I was so weight conscience about my car, I lost 30 pounds for the cause.. how did I lose the weight?

Rice Patties.. haha Rice. No just kidding, thought it'd be funny. I just bought a supercharger and couldn't afford to eat much for a week. Best of both worlds, ate less, got a 'go-fast' part and got rid of some weight!
 
im gonna go ahead and go through the head and replace and beef it up a lil, and build the bottom end...
