Hi,everyone.well i have a civic sedan year 97 with a b16a2 engine and i am preparing my car for 1/4 mile drag.Here is the list parts i have but not yet installed as some parts not yet ordered:
Engine:
Buddyclub camshafts stage 4
Buddyclub cam gears
Buddyclub dual valve springs and retainers
High compression 11.5:1 wiseco pistons 81mm
ECU chipped by xenocron redline 8800-9000 rpm.

Gearbox:
F1 racing stage 2 clutch kit
F1 racing 9.5 lbs flywheel
Mfactory Helical LSD
Mfactory 4.923 final drive
Mfactory gears ratio unknown...

So i would like to know what gear ratio will be better for my setup in 1/4 mile?Do i need to change all the gears or only a few?I hope you can help me in choosing the correct gears,i.e the most advantageous?Thank you.

Sounds like you are off to a good start with that 4.9 FD , What transmission do you have now ? is it a B16a2 tranny or you dont have anything and wanting to build it right now.

If you have a b16 transmission (stock gear rations ) with that 4.9 FD , give that a few passes and see how it goes with your power band.

I have most parts in the garage,yes it is a y21 gearbox.

dont waste your time with ebay stage 2 clutches. They are ****. If you are racing you need a 6 puck. You should be able to leave your gears as they are. Although I am not sure exactly how short they will be with a 4.9FD.

I had the stage 2 in my previous civic,it was great.I do not want to use the 6 spuck as its not reliable to drive in town.The car will not be driven only for drag purposes but also in town.

So i better forget the close gears.and get the 4.9 FD.

Jimster480

yea a 4.9FD is already going to have super short gears. But I was just saying that Ebay Stage 2's are not good for racing. I just had one with a Stage 4 pressure plate and it couldnt hold my power. Now I have a stage 4 pressure plate with a ACT Ceramic 6 puck.

i have already bought the stage 2.I'll see if i can get someone here to buy it,and jump on the act.so i'll stick with the 4.9.thank you.

If you dont want to blow all your money you can go with an ebay stage 4 or stage 3. They are atleast decent. And when the disk goes you can replace it with a ACT or Competition Clutch Disk. Just make sure your 6 puck is a ceramic disk and not a steel one. Because Originally I had a competition clutch Iron man stage 4, and that clutch was beyond insane. It was a steel 6 puck disk that gripped so hard the car would shake even if I dropped the clutch at like 3k lol.

Do some research on clutches(i.e. some reviews). I've heard, and had good personal experience with a variety of clutches(exedy, f1, stock). Hell, I put 250 to the wheels on a stock clutch. It lasted for 6 months or so. Not to recant on "jimster480", I've just heard mixed reviews about the ACT stuff. Never ran one; although, I am running an F1 6 puck stage 3 and it works great. I have a boosted b16. I'm only around 248whp right now though. I will soon go to a little over 3.

B16 or ITR tranny w/ LSD.

yea I am not saying for him to get ACT. I just happened to have a full competition clutch race clutch, so I only needed a disk and I found a 6 Puck ceramic disk that is a replacement for their stage 4 kit for $100 so I bought it. But a couple of my friends have had F1 racing clutches and XTD aswell. None of them were really bad. Except for my Stage 2 XTD disk with a XTD stage 4 pressure plate that couldnt hold my 270WHP for ****.

I remember i bought the F1 stage 3 6 spuck,it lasted only for 6 months.it even damaged the 7.5 flywheel.I do not want to use the 6 spuck anymore.thank you all for your valuable help.

Jimster480

if u wear it all the way down it will damage the flywheel because the rivets will come in contact with the flywheel.

thats what happened..
