Ok, well I'm not the most technologically sound guy on the boards, I have a 92 535i, M30 engine, single cam 12 valves, auto tranny.

Straight_6 suggested to me that I get cams.

I just need to know more about this stuff before I really get my hands wet.

Whats a good starting point? What should I go for? high end power? low end? Torque? hp? How can I get the most out of my engine?

I was thinking of getting a Jim Conforti chip to start. Its cheap and it has good ratings for my engine.

Also, there's a budget, so no suggesting rocket fuel ok?

I need a direction basically. Work bit by bit, going in the right direction.

The only problem with putting aggressive cams in an automatic is that unless you are really putting your foot into it the auto tranny will shift before it reaches the new powerband. Aggressive cams often lose low-end power, so they might even make your car seem slower unless you floor it.

I would first start small, and work my way up. I would get that chip, and something like an intake, and/or exhaust. I know these are the small things that everyone has but it all ties in with building and making your car more aggresive looking and much better performance. Of course these mods will probably not do as much as an affect as a cam, but that's just my opinion.

yea, but I was talking to MTRD about it, and he said I should decide whether I should go for high or low range power. Thanks guys, I think I will get that chip. and maybe an intake.

Yeah thats up to you on that one. I personally would rather have the low range. That's just a personal preferance i guess.

Can someone explain the benefits of both low and high range?

low range is more power at low RPM and high is vice versa right?

Correct me if I'm wrong, its still so new to me.

Well I think it's better to have the power for the higher range.

I mean, let's say you have more power for the low range. You'll have the pick up power or initial push right? But from there the power delivery won't be as strong as for a car setup for high range power.

Basically, if you were to put a car side by side and race (correct me if i'm wrong), one setup for the high range power (car a) and the other is setup for the lower range power (car b). So intially the "car b" would have the start, but once "car a" gets into the high range power, it will make up for the difference lost from the low end power. Therefore "car a" would eventually blow past "car b". Doesn't it make sense though? Well I read it from a post on a discussion like this almost half a year ago!

But, I guess it depends on how you use your car. If it's city driving I guess the low end setup is nice for getting past some cars instead of reving it high to get the power, but for me, I go with the high range setup.

Hrm I see, Thanks!

I think I"m just going to stick to basic mods for now. Chip, Intake, Exhaust.

How about a transmission conversion (auto --> manual)? hehe, but some ppl say might as well buy a new manual car then, I don't know.

or take the cheaters way which I like, drop in an turbocharger/supercharger, but $$$$

or a high differential? hmm

MTRD recommended changing the tranny, I thought about it, but I think I'll just stay basic cuz its an old car, and a big one at that, I dont think I wanna spend too much on it till I actually buy my own car, which may or may not be soon, but I dont want to look back and feel that I wasted my money on this car. After all, I didnt buy the car myself, it was my dad's car.

Basic for now, extreme maybe or maybe not.
