I know you're looking for na power, but why not just buy a supercharger for 5k? Earlier in the thread you mentioned you had already spent 4k in mods for only so little improvement over stock. I've seen a couple of supercharged 330i's in the 300+rwhp range by using superchargers. It seems to be the quickest way to get in that range for cheaper.

That wouldn't be a naturally aspirated engine though.

There are lots of good reasons to stay N/A (naturally aspirated... aka no supercharger or turbo) \

For one, it makes way more sense for a budget track car than FI. You go boosting a car that was N/A and your just begging for heat/reliability issues on the track. You could sort this out but it will be significant money. It's a lot more fun to get a whole day worth of track time than it is to get one fast lap and then spend the rest of the day trying to get it running again.

Why are people sh1tting on this thread? It's all ready back to stock and Brady's moved on to an Evo VIII?

No one cares if you can make numbers with FI...that's already been shown by parties numbering in the thousands. N/A is something that isn't considered all that often and Brady made a choice. Get over it and stop trying to make suggestions. No one cares what you have to say about a topic that has come and gone.

Thumbs down Read

Thanks for the reply Jared, you made good sense. Now Vicious, I've already replied to Zander with the same reply I oughtta' give you. Read the first sentence I wrote in the first post I submitted so that it makes sense to your little brain. You know, when I first joined this forum I was really happy, and I felt comfortable because I knew I was part of something that shares the same passion I do. People I could talk to as much as I wanted to about what I love, cars. But it seems like instead of sharing our opinions, all I see is competition in seeing who holds more knowledge- and frankly, it's getting out of hand and it's stupid. This sucks, some of you need to grow up. That or I just need to find a better forum. Thanks for being mature, Jared.

Udm you obviously don't get the point. This is a na thread not a fi thread. We already know what fi can do, we want to know what na can do. Duh. Please post somewhere else.

Wow, everyone having a bad day...

Honestly, FI makes way more sense than N/A unless you plan on tracking the car. Like UDM said, you'll spend similar money trying to stay N/A and make much less power than you will just slapping a supercharger on it. That being said, we all know why we are here, there are still good reasons for staying N/A. (even if that reason is simply the desire to achieve a goal) and though we are a small number, I feel we are doing a great service to the community by creating these libraries of information on the net.

Maybe I'm just in a good mood from installing Brady's Schrick cams this past weekend.

Let's all play nice, people.

I'm sort of a dork. I like to do things in an odd way. I know full well that I could have made more power for less with a superchager. This was a lot of fun, though. I was making close to ///M power without any extra weight under the hood of my car. Would I do it again? No. Not until there is an easy way for us to tune our own cars and I learn to weld. Tig is pricey and blew my budget on things.

With the Evo, I really want to run the crap out of the stock turbo. I know I could get huge gains by putting a bigger turbo on, but that's just not what I like. I blew 3 small turbos by overboosting them in my Talon because I didn't want to deal with lag and loss of low end. Of course, then I stubbornly upgraded to something slightly larger and loved it, but still...

I am REALLY enjoying the BMW back to stock. It's so smooth and quiet. I feel like an old man. If I ran into some money right now, I'd be happy to slap on a charger or a TT turbo kit with a quiet exhaust. But I'm not going to run into money.

They are pretty sweet!

I have a whole DIY that I am almost done editing and then will post up in the next few days.

The car is definitely faster, the only thing is that I'm sure I'm not getting close to the power level the cams are capable of producing in my engine. I feel some dead spots now as the revs climb which makes me think the computer is going haywire pulling timing and dumping fuel and who knows what else. I have a feeling that in the M54b30 which already has significantly longer duration and higher lift cams to begin with(than the M52tub28), the software can cope better with the bigger cams. This is probably why Shrick does not advertise the 264's as compatible with the M52tu. Its just too big a jump for the software. I also have no doubt that Randy Mueller at Epic will be able to fix this with an updated tune and the car will be making great numbers.

Yeah after I installed mine I've noticed zero hiccups.. Some very very solid gains up top on the butt dyno ... I feel like I'm leaving a lot of hp on the table having my redline at 6.5k also I have a great feeling there's a lot of potential from a solid dyno tune to take advantage of the headers and cams.. Honestly my goal is 250 rwhp.. I don't have an aftermarket exhaust so could anyone tell me that with my current mods a aftermarket exhaust could pick up with some ponies? I'm sort of out of options for making more n/a hp which I don't want to swap out for 272's too big of a headache and with the idle issues I hear about..

I was at 233whp at 6500. There was a spike right after that and I was at 234 at 7000. You're not really missing anything except more harmonics, unless you're needing to hold the revs for just another second on the strip.

Jared, I will be documenting the swap from MS42 to MS43 before the end of the year. Stay tuned!

Can't wait, I'd love to be able to run the M54 throttle body. Plus it will make it easier for people who are un-tuned to get into things like injector and MAF swaps. At this point, I may just have Randy tune for M54b30 injectors on mine as well.

Hey you should be! You've been a great source of info to myself and many others on this forum. N/A modding on these cars owes a lot to your trailblazing.
