Ok, so it was my first time to the track...ever, and let me say, was it ever fun.

What's with the launching pad; its like a polished basement floor. My first run (ever) i thought i'd launch at a nice 3500rpms and well, spun first, second and i was at the redline in third and i still hadn't gone anywhere yet. I dont' know if it was my clutch slipping there or my tires there, but i got the slowest run of the day at 20secs.

I tried all sorts of launching speeds and techniques, but i just wheel hoppped most of first gear to lousy 2.5 60' times and consistant 16.6's. I even tried launching at 1000rpms, but just bogged it. I then realized it wasn't the clutch dump, i would have spun a rolling start on that ice. Tried to moderately heat up the tires too but to no avail.

I think my other problem was, my car being a '90 teg rs, i used the stock intake mani and exhaust ('cept with a low mi civic ex cat). Big top end choker for the b20, as I was only average for the g2 tegs there and they all had there traction problems too. So the b20 mod only really hurt the 1/4 run. Better low end forsure, but that just ruined my launch; and the top end was no better than stock really because of the crapppy stock intake and exhaust. You would have to see the port size differences in the the intake mani to the head to understand here.

The only weight reduction i did was cleaned out the garbage (excluding my 50lbs+ stereo sys). Tires, were fresh, but cheapy stock sizers. Clutch was the original 333 000km unit; not sure if that makes a dif, 'cause it seemed to grab ok, certainly considering the big squack from first to second. And beyond that i just shifted regular like anyone else, nothing fancy. the engien is a '96 jdm b20b with K&N intake, 62mm tb and a b&M fpr set everywhere (no dif in times).

So the best of the day for me was 16.484 @81.493 with a 2.472 60'. At Luskville, Ont. yesterday.

I didn't feel too bad 'cause all the probe gt's were pulling 16.xx's and all the Cavalier's were 17's with the fastest gt of the night as 16.8 haha. Its no joke, all cavalier's ARE slow - embarrasing. A stock '02 civic si(r) was pulling mid high 15's so they're not THAT bad (he got traction ) considering the slow field

IM ALL BOB

well 1st things 1st.. lower your 60ft time... but also get a larger Cat or run a test pipe.. I've seen b20 with a stock size cat are somewhat restricted .. so I say open up the restriction.. get some better tires and practice

Downey

not to bad considering its ur first time and the lack of traction. Get some stickier tires, and practice the launching. U should be able to pull 2.3's 60fts. Good luck next time!

tinkerbell

yeah, the first time is always hte WORST!

sounds like a really slipery track there???

was this a misprint? if not - new clutch time!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!

this will improve times instantly.

this is the best rule for clutches: go as strong as you can afford!

then look at tyres, and check out your intake for improvements...

hth,

t..

yep, it really has 333 000kms on the original clutch. It still was within specs when i measured it so i put it back in (money...). It seemed to grab ok, but how would i know if it was slipping. wouldn't the slip be in first gear if any? When i was just hopping like a kangaroo?

d

tinkerbell

cant really say, i didnt see it.

sometimes people will be spinning and think it is their wheels - but it is realy the clutch.

you will SMELL this though, did you notice a burning rags smell?

a worn clutch will still grab and hop, but may also be sliping as well...

(clutches are weird!!!)

you can get them rebuilt as opposed to getting new ones, thats what i did: cost about $350 canadian for a 660KG pressure plate and a high density organic pressure plate.

works very well, cant chirp in third, yet - not enough power...

anyways, at the track practice is the key to consitency,

so go to the track as much as you can!!!!!!!!!!!!!!!!

Quick question....I have a b18c1 in my 96 ex, I have i/h/e, is the stock ex cat hurting my performance?

JalopySiR

Wow, umm. I ran a 15.7m my first time with my B20 setup, which was almost the same, 90-91 ECU, IM, EXhaust manifold, BTW, this was in a CRX tho, with the stock intake. Your trap speeds are pretty low tho...I was trapping at 89... maybe it's just the weight...also my best 60' was a 2.4 also...

daver

well, i could see your 300lbs less make that much difference i guess. If you could get 2.4 60' with that much less weight, then it must be my tires (or the slick track here). I think 90-91 mani setups must really hinder it, considering the numbers and times people are pulling in their obd1 civic setups.

I didn't smell any clutch burn, tinker, just a lot of burnt rubber from all those muscle cars

d

G2turbo_terror

what was your tire pressure at? that makes a huge difference. You should get a newer manifold, I don't know if porting the 90-91 will help or if the 92+ is just physically bigger but if your low on funds try to trade yours to a junk yard or something. G2s arn't exactly the lightest cars either, need weight reduction

daver

i had the tires set at an everyday 32 lbs. I know its high for dragging, but i didn't have a portable inflator to reinflate. Make a huge diff eh? What do you recommend, about 24lbs?

d

daver

most likely to some degree, i put the ex cat on my teg because it was low milage (i could see thru to the other side!!) and it was free. It looked to be the same size as my original, except it was slightly twisted offset.

StorminMatt

WOW! Those crappy 1990-1991 Integra parts must really be killing you guys. Because I ran 15.0 at 92.6MPH with my 1988 Civic HB (no weight reduction and super tall 1993 LS YS1 transmission). And I KNOW that the car could do MUCH better with a better launch. By the way, the B20 is running full 1994-1995 electronics (P75 ECU) with a 1994-1995 intake manifold. Maybe all of you should just ditch the pre-1992 stuff and get a P75 ECU and 1994-1995 manifold (the 1992-1993 is the same as the 1990-1991). As for the exhaust manifold, the LS manifold is the best stock manifold out there. The only thing better would be a header.

SuperCivic

are you guys running b20bs or b20zs? from what i've read there's a decent difference in the two, especially if you are running stock motors. i've yet to take mine to the track..it's only a week old

Jonathan_ED3

I know of several guys doing 14's N/A with mininal of mods in Cavaliers....

SuperCivic

??? did i miss something???

Jonathan_ED3

Obviously you mised this:

And then my statement:

tinkerbell

you cannot run a factory stock B20B that you have read has 126ps.

it has a big manifold.

but anyways...

enjoy your new engine, is it a B or a Z?

t..

daver

its a b20b mr., but jdm. they seem to pull off teh same numbers as the z's here.

14's n/a with cavaliers? Can an exhaust drop 2 full seconds off a cavalier? Maybe this track was vertical...

d

Jonathan_ED3

yeah that's it.

CAI, header, full exhaust, high flow cat.

14.8 @92

with a z24.

SuperCivic

stock meaning stock internals, no vtec, etc. i know a stock b20b has the giraffe style intake manifold. but there is a compression difference between the two. the b20 w/ highest compression, according to the data i've seen, is the b20z, 9.6:1. next a version of the b20b in japan, 9.4:1 usdm b20b is 8.8:1. from what i've heard...there are several versions of the b20b in japan in 3 different cars..only one of the models runs the higher comp b20.

SuperCivic

http://hybrid2.honda-perf.org/tech/b20/b20dyno2.html
the red line is b20z, blue is b20b w/ same mods. this is usdm b20b..some versions of the jdm b20b are closer to the b20z, but not all!



and who gives a damn about a cavalier anyways

I would suggest lowering tire pressure a little, lowering mine from 32 to 24 made a .3-.4 second difference in my launch. If $$ permits, give the skunk 2 manifold a try. They are making some good power and if thats not an option, atleast ditch the pre92 stuff. Most important, get to know your car. Nothing makes a bigger difference than knowing that YOU aren't the cars weak link.

StorminMatt

I have a hard time believing that bolt-ons can drop ETs by two full seconds on ANY non-turbocharged car. This amounts to a gain of somewhere around 50HP. And you are NOT going to see this with these few mods. Something sounds fishy. Like maybe there is a blue bottle hiding somewhere.

As for the pre-1992 stuff on the B20, I guess I should change what I said somewhat. Specifically, the 1992-1993 ECU is OKAY. But the 1992-1993 intake manifold is NOT. The problem here is that the port size is different on 1990-1993 B18A heads and 1994+ B18B and 1997+ B20 heads. The intake ports on the latter two are larger than on the 1990-1993 B18A. This means that if you are using a pre-1994 intake manifold on a B20, you have the small intake runners of the early style manifold opening up into the larger ports of the B20. If you know anything about fluid mechanics, you know that this is a definite no-no. So at least get the 1994-1995 manifold. Or get the Skunk2.

I fixed my dragging semi-siezed rear brakes and it feels faster now, so thats a plus. Yep, the tires are big. The cavalier that i did beat had almost .15s better 60' and it took me til half way to pass him and i beat him by .5 that time, so i should be well into the 15s with just a bit more traction.
