Okay first off I am getting a 3 series for my balls out race car (not sure wich one yet) but anyways. I would like some input on a few questions. I am thinking I still would like a bit of speed out of my E34. So heres the list.
1. Intake (already done)
2. Exhaust
3. Chip
4. Headers
5. MAF Sensor
6. High output coil packs with good wires
7. Maybe a performance CAM.


What kind of perfomance do you think I would have with this list of modifications. Speed, 1/4 mile time. Top speed, 0-60. Just info in general. Let me know. Also If there is any other minor upgrades I didn't think of please inform me as to what I could do. Performance not handling as I have already taken care of that side of things. Give me your input please. And no I will not be adding a turbo. I am going N/A with this build.

Thanks for the help.............................................. .............................

S50 cams. All of that might get you to 200hp to the wheels.

1. Intake (already done)

2. Exhaust- OEM exhaust is none restrictive anyway, but aftermarkets weigh less

3. Chip- TMS do a chip to account for S50 cams $350

4. Headers- Equal length headers, 5-10hp maybe

5. MAF Sensor- You already have a MAF?

6. High output coil packs with good wires. Unless you boost it there's no need

7. Maybe a performance CAM. S50 cams or Shrick

Performance wont increase that much as far as figures go but the car will drive differently, I doubt it will make over 200rwhp
