[ryder_23]

You can do alot of things to improve it if you want...you can turbo or supercharge it...how did it feel to you?

[silverEL]

where I live the circuit is only for the 1/8 mile race... so I dont know the time for the 1/4.

[Loose]

that should be about a 14.9 1/4. A bit slower than it shold be if you ask me.

[ryder_23]

DO you have an m3 tranny or 325? how bout rear diff? Can you drive stick good?

The only things the car has is an M3 95 engine and the 97 M3 wheels. then everything is 325. icluding the tranny.

[maurim3]

Does anybody know the 1/8 mile time for a M3 US Spec?

[Loose]

should be around 9.1 to 9.3

would an cone air box improve to that point.? and my service light is on red. would the service make it run faster? changing the oil. and all the filters?

[maurim3]

What should be the first thing I should do to increase the power in my car. ?? It has a totally stock engine. no mods, I need a 0.5 secs improvement in a 1/8 mile track. What can I do?

[ryder_23]

U've asked this question a few times already....
Buy an m tranny ....then buy a supercharger....
also goto www.dtmpower.net where you can ask all the bmw questions you want, and will get alot of answers there.

But do a search first, because i'm sure its been asked a 100times over there

an engine swap into a 325 does not make it an m3...not even close

[three.eighteen.]

a big afm kit usually gives you a good gain

Im really sorry if I bothered you with my questions... but the thigs I dont have 4.000 $ for a supercharger.... or a turbo..so I want to Know what can I do to improve 0.3 or more secs in an 1/8 mile that doesnt involve spending a lot of money. like air filter o chips... I want to know If anything cheap can buy me those fractions o a sec. I´m really sorry.

[ryder_23]

i wasnt bothered, i was refering to how you can keep it in the same thread, instead of bringing it up in 3 or more threads, hence why the admins merged it...you didnt say anything about price you just say make my car faster...

I bet even getting a new tranny, like i've been telling you and you seem to ignore, could help with your timing, not sure the exact numbers from 325 - M , but since M tranny is for the M, well its obviously there for a reason....Try the other bmw websites, see what they say...they will know best.

[ACS-e36]

first of all... get a M3 diff because it had LSD. that will help you ALLOT. second a m3 tranny should help a bit too... not too much but better.

[three.eighteen.]

m3 tranny can take way more power than a 325 tranny

for cheap power: pulleys, exhaust, headers, chip

yeah but more so than most cars htat put an M badge on their cars!, at least he has th emost significant M part, the engine!

[Ben]

I ran a 10.2 1/8 mile and 15.7 1/4 so that might give you an idea even though my car is nothing like an BMW.

Ummm doesn't the car have to be supercharged for pulleys to actually do anything?

Not easy or cheap to find hp in those engines, and $4k isnt much money.

What car do you have? and is it tuned? I dont know if the M3 17"rings would help o make acceleration worse.. i bought them last week. and the interior too. its all ///M. Im only missing the bumpers

Yes it is for a 0.3 increase...In my opinion.... would a mantainance help.. changing all the filters and stuff?

He drives the Wagon Queen Family Truckster...:rofl:...So you got all the suspension? Tranny, rear diff? And isnt the M chassis somewhat stiffened or slightly different then stock 3 series :dunno:

still, i wouldnt put an M badge on it, for its not truly an M, your car no matter how much M stuff in it, your VIN on your dash/trunk will read 325 not M3

[three.eighteen.]

you are missing tons of very important m parts:
-m3 brakes are bigger
-m suspension is different, sway bars attach to different place, different control arms, different bushings
-m3 clutch is larger
-m3 tranny is way stronger
-LSD
-the VIN starts with WBS...the rest are WBA (because of this your car will never be an m3)

I have a MK2 VW GTI with a 16V swap and some engine work done.

[maurim3]

I never said I wanted to put an M badge on my car... it clearly sais 325i... And I love that becouse no one expects it tu run like it does... And I love their suprised faces when they dont understand what happend...

[three.eighteen.]

phew...in that case, good job...i just hate seeing german rice...i'm sorta partial to the 332is badge, or if you get a supercharger, go for 332sc :thumbsup:

I did a [email protected] in the 1/8th, which came out to a 14.5@93 at then end of the 1/4.

Seems like the gearing is affecting your times, so definitely get the tranny and diff ASAP.
