m3 into my 325

[eurotrash1]

i would start out with a chip and work the stock motor till it cant take no more than turbo it. you would get more power with the turbo than with a m3 set up.

I'd honestly save your money and buy the S/C kit, then see what you want after that. Mine is a 93, ESS powerdyne at 8psi, has an M52 exhaust, and bigger injectors on a chip tune with a snow kit. I'm putting 270 to the wheels without tuning in the snow kit, and i'm pretty content with it. With a spot on dyno tune and the snow kit tuned in, i bet i could hit 300.

I'll be going with a custom turbo setup eventually, and would suggest that. Sure you can buy the s/c kit for 4400, but then you're a little stuck power-wise. Sure, 300hp seems fine for now, but what about after driving it for 6 months and deciding you want more? After that AA kit, there isn't much left to do except the basic i/h/e stuff, without tearing the motor down. Those wont yield that much of a gain. Custom turbo's will cost a little bit more, but, 300hp shouldn't be difficult to achieve with a correctly sized turbo and some support. Larger injectors and a well pieced kit with a good tune would get you there and then some, i'm guessing.

My ultimate goal is 450whp, and still be streetable. Just gives you something to think about when you finally get down and decide. Keep in mind if you're going turbo, you'll more than likely have to scrap any i/h/e you buy for your car while it's N/A.

i dont want to turbo charge it i just want like 300 at the wheels with a s/c i dont care if i get bored with it after a while because when im done with this project i want a nice e30

Then buy a kit, seems like you already have your mind made up.

Have fun spending more money than necessary.

s/c is less than a good turbo tuned right with reliable internals but thanks

[zx666r]

You can run a basic turbo kit with stock internals and a thicker headgasket for less than the price of the supercharger, if you search. I never said you could build a turbo 450hp car for less than it will cost to get your car supercharged to 300.

I think your car may have too many miles for the turbo or s/c. Maybe you should rebuild the engine, and while you are at it, polish the ports. Also dont waste money on bigger injectors. The best thing to do is get new ones, or better yet, get them cleaned and restored.

Mine has 160k on it, and it's still pulling on LS1 cars

i think its better to get the M power...cause u`ll get headech from tuning, but M power is pure 289hp and its easy to hit 350hp with it just little changes like cams..ECU..air intake filter...manifold intake....exhaust kit ...etc....

i believe m50b30 only make 240hp

I agree with this, because I was looking at buying an m3 engine for my car but it was going to cost me $1200 for a higher milaged used one and for a descent low milaged one about $2300 and then to have it professionally installed about $1100, but also you would have to change a lot of different things just to make the engine correct with your car, which adds up quickly.

I don't get where you all are getting that a turbo is more expensive??? I don't believe they are, and the biggest bonus to a turbo is the adjustability. You can start low and build up from there. With a supercharger you have to not only look at the ridiculous price of the unit to start with but also down the road when you decide you want more power. Now which is easier- turning a knob on a manual boost controller or changing pulleys and all that crazy stuff, which also only nets a couple lbs. Thats my input ; )

if i was to get a turbo where would i start. they sould like they take a lot of time and effort just to get them right.

[cool_boy_eddie]

i d say turbo ur current engine if u r willin to spend the money
