Lightweight Flywheel? - BMW Forum

KevinTS · 03-16-2005, 09:50 PM

I was told by a bmw mechanic that a lightweight flywheel would be a good upgrade for HP. Is this true? If so where can i get one for a decent price?

he is right it is a good upgrade. It takes a lot less energy to turn the wheel.

There is one that site has alot of stuff, I ordered a performance chip from them and love it. The flywheel should increase your throttle repsonse times and can be a good mod. I would not do this as one of the first things however. There are alot more mods that you can do first that will also be cheaper.

performance software
cold air intake
exhaust
cam shaft
tires/wheels

these are all the more common ones it seems.

i already have a chip i am going to get an exhaust cold air intake headers and the flywheel at the same time. The mechanic told me that the camshaft will make the car shake at idle speed it will make it feel like a racecar that's what he said. Is it still safe to put a camshaft in?

a flywheel does not actually increase hp but lets the engine rev faster. i believe a ltw flywheel helps the most in first and second gears. i plan to install a uuc stage 1 flywheel at the end of the month. and you will also probably need a m3 clutch.

The cam should not make the car shake if it is installed properly and timed right. Alot of people put in used M3 cams. There are some people here that have the cams try and search for them. I can't remember for sure but I think it was jrhaile. They are supposed to be a great mod especially if you have all the other stuff, you will need to reprogram your chip though. Depending on company they might do it for free, some charge $100 to do it.

I vote for cams now while you do all other stuff then flywheel later with clutch and short shift kit.

I am thinking about getting a AA tuning aluminum flywheel. Is this a good one? How do you time a cam shaft correctly? I though M3 cams can only go on M3 motors am i right or wrong? How do you reprogram a chip?

The shop needs to install the cams properly.

M3 cams will fit in your car I believe (someone with a e36, confirm?)

You get a company to reprogram it for you such as AA Tuning or Turner Motorsports.

Yes, I would have the shop time install and time the cams, you could do it but it would be real difficult and you would probably need to buy more tools to do it.

E36 M3 cams will fit in any E36 motor, like I said there are people on here that have done it.

that is a link i started a while ago about cams. jrhaile was the one who put them in recently

Right, you get whoever you bought the chip from to reprogram it for you. TurnerMotorSport is free for 6 months then after that charge $100 to do it(which is the price they sell the chip with the cam programing already on it $250+$100 reprogram=$350-price of cam chip)

AAtuning is supposed to be a reputable source also.

Which company is better for a lightweight flywheel Turnermotorsports or AA Tuning?

jshearer · 03-17-2005, 11:58 AM

The one on aatuning says that it is for the M3 I don't know if you can use it for sure on your car. It weighs in at 12lbs and is $689. The one on turnermotorsports shows it is for the 92-95 3series. It weighs in at 10lbs and is $559.

I would go with the turnermotorsports.com flywheel. I trust both companies, but the turner one shows that it is made for my vehicle(and yours). Whereas the AA one says they only make one for the M3. PLus the turner is over $100 cheaper. I ordered my chip from them a couple of weeks ago and got it with free 2nd day air shipping, they may still be doing that also.

I would also not rule out the cams for later, that is supposed to be one of the best mods you can do, but I think you will be happy with all the stuff you are doing too. It is rare that someone starts to mod there car and says "ok I am done now, I will never do anything else", there is always something else. Keep the cams in mind.

OK from racing porsches and other cars a lightened flywheel is really not a good idea for a street car with manual transmission.. You will find it harder to keep the engine revs up while shifting and driving in traffic. Lot moreof a tendancy to stall the car.

For Autocross and racing yep is well worth the dollars if you have the engine/trans out so you can change it.
