I can't decide and I'm torn between a Forced Induction or Naturally Aspirated setup. This is for a 99' M3 that has 45K miles. The cars in MINT shape. The indecisiveness is between the following:

1. Active Autowerke's C-38 Stage 1 Kit

2. Turner Motorsport's Stage 4 Kit

Any input would be helpful. Thanks.

Go turbo, Technique Tuning Stage 2. You will never look back, insane quality and an amazing tune, you can't go wrong with this kit...

Turbo...uhmmm.

woh...that kit's almost 8K. No thanks. Let's keep this as close to 4 as possible.

Screw FI and NA...real men get midgets to pull them around in jets.

:lol

So you want to spend around 4K? Whats your power goal?

For 4K you could piece together a kit, but then comes the price of tuning...

I would go with a stage 2 AA C38 stage 1 kit...
You will definitely want more power so you can always upgrade to the stage 2, then a 3 inch exhaust/M50 manifold...

I'm not really looking to hit any numbers...the cars a daily driver, so anything that's reliable and holds up is mostly what I'm looking for. I won't/can't get into numbers game because it's always disappointing and completely dependent on so many variables.

You know what...the TT Stage 1 Turbo Kit looks real nice as well. But even then...$6,800 without installation. Damn!!

AA C-38 Stage 1...then maybe in the long run upgrade to Stage 2?

I'd say go the C38 Stage 1 and in the future the stage 2 upgrade...with an M50 manifold and the stage 2 you should be around 365-380whp which would be pretty sweet. I almost bought the TT stage 2, and C38 stage 2, I am still stuck in limbo...IDK where to spend my moneyz.:(

save it. you'll have to pay for gas one day.:eek:


oh shit:devillook

Isn't this the car that you purchased two months ago with a s/c installed that you promptly removed a few weeks later? What's made you decide to reconsider FI? I seem to remember you saying that you were not a fan of blown bmw's and wanted the car to be NA. :help

I bought the car for the car...not for the supercharger. Besides, I'm not a big fan of forced induction on BMW's. If I were to mod the car, I'd pursue the NA route.

:rofl2 Yea WTF is going on here..

This post is experiencing time travel.

The the more and more I spend time looking at the best possible NA route, the more and more I feel the money isn't well spent. So, I'm re-considering the FI route again, but with a more updated package. The ERT kit that was installed when I purchased the car was a bit out-dated. I was using the stock injectors and running like 3psi of boost. It just wasn't for me.

I think the NA route would be best for what I do on a daily basis. So, the Turner Kit it will be.
