    e30 325i vs e46 m3

    First let me say my car is not a stock e30 325i its turbocharged. I recently just blew the head gasket, and put it back together a few weeks ago, but i haven't been getting on it because i thought i had other problems. Anyway the car seemed to be checking out, and i needed a boost fix. So i hooked up the water injection, put the larger injectors in, and put some colder plugs in. I was ready to go for a ride, hoping things were set, and i wouldn't blow another head gasket.
    Anyway i was cruising down the highway at about 75-80, when a few nice cars roll by me, i get some head turns, but i continue on at the same speed. I was still a little timid about laying into my car agian. At the end of the pact though about ten seconds back there is a black e46 m3. I still didn't really think right away ok i want to race this guy, i was just admiring the car this was the first e46 m3 i've seen in my area, (i live in a small town in CT). Im looking over at it though because hes kind of staying on the side of me. Then i hear what sounded like a downshift. I admit my heart starting beating faster. So i downshift into fourth (i have pretty short gears so thats the lowest i could go) I was on sure what gear he was in. Still side by side i look over, and he gives me a head nod. I lay into the gas pedal, he jumped about 1/2 to 3/4 of a car on me, but fourth gear with my turbo is a strong gear, and i was edging up. by about 130 he was about 1/4 car length on me, and we shut down at about the same exact time. I know he could have kept on going, but i glad he decided to shut it down, because i didn't want to push my car anymore on its first run back out. I forgot to mention i was running 14psi with a T-60, and was probably in the area of 300whp. Plus my car weights around 2,600 pounds with it lightened. I don't think i'll run into an opportunity like that again so i had to take it.

    Nice!
    I'm not really familiar with the E46 M3, what kind'a numbers do they have?
    ..And it's nice to hear your car is up and running again!

    Thanks guys, i just need to get a real tune on it, with some real engine management to make it the way i want it. Run about 16psi with some 100 octane, and see what kind of numbers i can get.

    And then again, I think it's just the rating system (hp vs. bhp) that makes a difference. No?

    And I think they have like what 270 torque, atleast I know its in the 270's. And they weigh in the middle 3K range, maybe alittle less. So you definitely should have handed him his a**. With 300 whp and only weighing 2600 pounds. He was proabaly in third gear when he down shifted though, because if you both were in fourth I dont see how you would have only kept up with him like that.

    Good death, but like other people where saying with 300whp you should have handed the guy his ass. Maybe he wasnt stock also though?

    Nice run The T-60 can make all the diff. in the world. I've driven BassMasters E36M3 (bimmerforum member). He's got a T-60 aswell; a revuilt engine, etc. At low boost the car was making 500-600whp and it's capeable of 1000whp on high boost. It's the fastest thing (from a roll) that I've driven to date. It would ruin anybody's day that went up against it

    Have you done cams, timing gears, pulleys, and flywheel? You may also want to lower your rear gears so you can maximize the boost you're running.
    Maybe out of a 325???
