Well I swapped the motor in my 90 teg with a 98 b18b and a 12 lbs flywheel.
The motor pulls consistanly throughout the power band but not as quick as I think it should. It feels as though my timing is retarded or like I need an alignment, it just feels as though its lagging, any suggestions please

 

Well I don't know If anything is wrong...check this out...I had a 90 4dr LS teg, sold for my 95 GSR. The only thing my 90 had was CAI, and whole in muffler. When I drove my GSR (next day) with SRI and aftermarket muffler, I KNOW It reved slower than my old 90, (until about 4500rpms of course) I think the early model b-series had a little better flow down low, and way less up top. That's my expereince.

 

im wondering if it poor ehaust flow, i have a canister muffler with a silencer in it , i removed it , but not much diff there. Im not sure what it is.

 

who installed flywheel? u sure see them pu that on?lol i heard that when u put aftermarket flywheel it rev up like bike..

 

My 7 lb aluminum ClutchMasters flywheel makes my engine rev like a bike, and my stage 3 clutch (also ClutchMasters) makes it grab like a Mac truck.

 

me and a friend put it on..LOL

 

Tune up time?

 

I have an ACT Streetlite 12lbs flywheel on my 93 LS. It revs a little faster than stock but not anything dramatic since its only lightened to 12lbs. When i change out my tranny im goin for the Prolite. I think you just expected too much from the flywheel, i kno i did lol.

 

huh.. thats wierd. I always expected a noticeable difference from stock to a lighter flywheel. I have the ACT 8 lb prolite wheel mated with a full face disc and the rpms drop incredibly fast. I have to keep the rpms up when up shifting, but acceleration is also a big difference. But when you do change your clutch next time, upgrade to a lighter one. I'm sure you'll love the difference.

Exactly. A 12 lb. flywheel honestly isn't all that light, which is why I always recommend the much lighter CM/Fidanza piece if anyone is going to go through the time and expense of swapping flywheels.

 

when swapping out flywheels...i've always stuck with 8-8.5lbs flywheels. i've had comptech, exedy, and now i have the prolite sitting in my room ready for install(waiting for my wife to learn how to drive my car before i slap that on along with a new 4 puck). swapping from the stock to a 8lbs flywheel you'll definately notice a difference. acceleration is increased dramatically, rpm drops a whole lot faster, and trying to drop the clutch while launching is a whole lot harder as your rpms will drop by at least 2k rpms. best thing to do then is feather the clutch...

 

really cant notice the difference my self.

 

I've got a 7.5lb Fidanza flywheel. Mine runs through the gears like a bike.

light flywheel

 

ivwe gotta 12 lb and i can tell some difference but its no street bike

 

i have a 12 lbs flywheel... it feels just a tad bit better than stock, but i wasn't expecting too much.

i'll definately go lighter next time.

 

how light is to light? I heard that the lighter the flywheel the more prone your car is to jerking during shifts. So wheres the compromise (in lbs) in fast revs and non jerkyness

 

i had a clutch masters 7 or 8lb flywheel and my throttle response was a lot better than stock. alot of people say that drivability around town suffers but i did'nt have any problems at all. with my current gsr, i was going to go a bit heavier, like 12 lbs, but after hearing all those testimonies about them, i think i'll go back to the 7-8 lbs.

 

12LB flywheel is nothing dramatic...more for the Launch and Drag type of driver

Have some fun, drop in a 9lb or lighter...You'll appreciate it more, if you're the nutty Initial D type of driver.

 

reading this is making me want my toda clutch kit now damn slow ups

 

Also the thing to think about is that the flywheel stores energy for the engine. Its the thing called inertia. When you spin a 12 lb disc, it wants to keep spinning after you let the power off of it because of the weight on the disc, a 7 or 8 lb disc will just stop spinning faster because it has less weight to keep it spinning. The 12 lb flywheel will be good for auto-x because of the elevation changes and when you go up a hill, that stored energy in the wheel helps the engine pull and get you up that hill. The ultra-light weight flywheels are better for drag because you need that ability to get the engine revved out and go through gears, and your going in a straigh line with no change in elevation, except for down. Hope this helps alittle.

 

so what do you guys recommend on a car that is a daily driver but will do it's duties as a weekend track car too?

same here

 

I'm looking at doing either a tilton or exedy twin disc clutch, and the more, and more that I read, everyone says if you're going to daily drive the car, just go with a stock lightened flywheel. They make a combo where you send in your flywheel they lighten it to 12 lbs, because the Tilton flywheel only weighs 6!!!

 

7.5lb Fidanza here. Notice some difference but not alot. Nothing crazy and absolutely no downsides.

Theres alot of myths about light weight flywheels started by people who aren't speaking from experience.

 

i had teh ultralight jun flywheel at 8lbs. i really think you could go even lighter. when i took it out after the teeth were chipped cuz of my starter, i went back to stock.. how boring.

remember how fast you rev out also has to do with the length of your stroke and the tranny. i've driven a b16 with stock fw, and b16 tranny.. that thing revs out pretty fast too. not as fast as a gs-r with a 8lb'er but its close
