Increase HP 1992 535i?

Do you guys have any tips or experience in gaining horsepower? Big horsepower gain? Little horsepower gain? I'm only 15 and really have no experience with this kind of stuff. I just want to know what are good things to buy and what aren't.Around $200-$400 budget, how much HP could i gain with this amount of money to spend?
Thanks in advance

A performance chip will give it a little extra. A used well regarded brand(Dinan, etc.) is preferrable to the unknown e-bay cheapies.
You'll need premium fuel with them.
Forget so called cold air intakes, the factory set IS a cold air intake and flows just fine. Maybe a little to be gained with exhaust but the only worthwhile ones are expensive and again the factory set up works pretty well.
M30s love boost if you are so inclined and this is really the best bang for your buck if you desire more than a few extra ponies.

What he said. Chips are good but provide just a little. Turbo and suprecharged turbo systems will give the most but are $$$$$. Exhaust systems, unless in conjunction with a turbo system or headers will do little more than just improve sound. At this pint in your E34dom (LOL) you should concentrate on learning your car and putting in the required work (Suspension, engine, cooling systems etc.) This is assuming that you just got the car.

Just my opinion young man. Hope this helps.

No disrespect intended Dionte, but I'm confused. In one thread you are looking for better MPG. In this thread, you are looking for more HP.

For the most part, more HP = less MPG. Just sayin.

Yeah sorry for the confusion, i just thought that turbos increase HP while increasing mpg as well. I just found out that turbos mainly increase power for older cars while the new cars have smaller engines with turbos in them.

They aren't mutually exclusive, the goal of both is to increase efficiency. The trouble with HP is folks tend to use it

What affect does a turbo have on an older engine? I was thinking about getting a KN air intake for $169 and upgrading the coils from Bav Auto. Any thoughts on a cold air intake, coils and a chip?

I have an EAT chip in my 535. Made a remarkable difference especially in the midrange. I am very happy with it.

The next step up would be the Miller MAF conversion. I honestly wish I had done this. The stock AFM is the big restriction, the conversion eliminates it. This with a Miller chip would be my favorite set-up short of a turbo. The turbo done right will cost thousands though.

Same as it does a new engine, it feeds it positive pressure. Some engines can not handle this and come apart in various ways. Some are tuned wrong and come apart. I do not think there is a turbo kit for your car. Consider a 4.0L six speed swap.

The chip might be worth a little, though your car was tuned for premium from the factory. No love for K&N here, the coils are unlikely to provide any benefit over working stock versions. You car is well set up for cold air intake from the factory.

The Miller MAF upgrade and WAR chip looks like a good combo

The chip might be worth a little, though your car was tuned for premium from the factory. No love for K&N here, the coils are unlikely to provide any benefit over working stock versions. You car is well set up for cold air intake from the factory.
IIRC there's no documented turbo application for the 530i (unless you have the euro m30b30 then you'd have to research m30 turbo builds)
The m60b30 is considered to be the redhead stepchild of the lot. So there's not much available for it.
That said, Sled is right.
Doing a swap for the larger 4.0l aka m60b40 and six speed trans would yield the better results.
From the m60b40 platform you can chip it to wake it up.
DUD chips come highly recommended for the m60b40 powerplants.
He's usually onBF.C so you can personally contact him for more info on them.

For FI most do Superchargers. Gixxer and costa are the resident owners of supershargered 540 cars. I'm sure they'll try to assist you.

Forget a turbo. It will cost more than your car is worth. Do your suspension next, then if you can afford a chip do that. With a 5-speed my most fun upgrade was an M5 clutch with a lightened flywheel.

The guys name is Mark D'Sylva, the company is E.A.T. google it. I think it was $250.

I personally wouldn't want to mess with the WAR tuner, I want plug and play. They do a single tune chip and MAF conversion for less, that is the one I would go for.

Kid, honest truth is, I know you just got the car and you're thinking "how can I make this thing go stupid fast?" but you have no idea how to handle how fast it is already. A 535 with a stick will keep up with slightly newer and lighter BMWs, even. Fast. So get to know the car, and upgrade brakes and suspension first. Otherwise you'll pour 5 grand into it and have it totaled within the week.

I understand where you're coming from. I'm trying to get my important things done first on the car. I was thinking maybe over time what i could do to the car to give it a little boost. Thanks for your opinion.

Mein Auto: 1990 535i & 2001 540i
535 hp gains

Hi Dionte,
I have a 1990 535 manual. I bought it in 20001 with 104,000 miles on it. Straight stock.. It ran great then. It is my daily driver and now has 260,000 miles. Over the years I have added a K&N intake , Bav Auto chip, throttle body spacer, and free flow exhaust, lowering springs, Bilstien sports and 17" wheels. Any performance gains have only been realized at 4,000 rpm and over. The car still runs great and I still love it. As far as significantly increasing HP, there is no replacement for displacement. I also have an '01 540 and there is absolutely no comparison in torque in the low to mid rpms. Save your money. Your stock 535 is plenty cool.
If you need more HP, get a V8 but be prepared for $$$ in mantainance costs. Welcome. DBA

this has been covered 100,000 times on forums.. try searching..

keep it simple.

1)intake
2)exhaust
3)chip

DONT, but if you wanna challenge a friend or something. take out the spare, back seats,truck carpet,even passenger seat..

will do more than you think and its free..

stage 2 cost wise, getting a or swapping from a 540i /6 its freaking fast

stage 3

boost


and remember the other cost's of making your car handle all that power.. brakes,suspension, tires,fuel delivery...ect




**** honda

I agree with Drew and luvmye34....we've all been excited with our first car, thinking of ways to make it better/faster, but the honest truth is, assuming you are like most of us at that age (no unlimited trust fund to draw from), you need to get the car running/stopping/handling the way it should first....you've got a few threads started already with problems that could consume some effort/time/money as it is....possibly upgrading as you go on needed repairs anyways ie: control arms, misc. bushings here and there....a 535 with a stick is a pretty fun car as is, as luvmye34 stated.....appreciate the youthful exuberance, just trying to point you in the right direction, it could get very frustrating to pour money into a car and then get disheartened chasing problems all the time
