Want to give my 94 e320 more power?
 

Whats the way to go . Do they make a chip.

I was thinking remus exaust new pipes from header back but thats small gain.

Any good upgrades?

I had nitrous on my m104,a 125hp wet shot,bought the kit used on ebay for $350. Its the cheapest way to go,instead of forced induction.Chips are a scam,they fool your computer to think incoming air,or water temp is cold.You can do that yourself with a 5 cent resistor.

Mercedes isnt known to leave much if anything on the table. I doubt there is a single bolt on that you could feel from the drivers seat. If you want real power you will have to spray it or boost it. Engine swaps are also an option.

While power is hard to come by there are a lot of options for braking and suspension upgrades which IMO you should look into first before making significantly more power than stock.

Nitrous-

I did it on my m102 190e. A very cheap (~$400) nx proton kit. No other adjustments or tunes. I sprayed 150, engine could reliably handle 100hp all day. There's a video on YouTube somewhere.

It made that gutless turtle into a respectable car.

Any other bolt on is a waste of money.

Ohh nitrous huh thought that would be final resort. Suspension ive done all new tie rod's and center link. I have bilstein shocks and struts im waiting to install once the weather breaks.

As for springs im trying to find a spring that lowers the car slightly. Just an inch .
Any idea on the springs?

My oem air box i took out and drilled tons of holes in it . No holes facing the engine side no hot air needed. The car stock has some balls surprisingly. I might go exaust next for suond and slight power. I had remus before it suonds so nice and smooth but deep.

I removed the triangles plastic parts inside the grill to give more air into the engine bay,took out the skinny intake tube going into air filter,made a larger one,wrapped exhaust manifolds,modified thermostat,to run cooler.Never goes over 80c,removed Cats,mufflers, and went with one single Borla race muffler.Hoping to buy a turbo bandit kit soon.

Unless you have sealed holed area to the front of the car ahead of the radiator, you will likely be picking up hot air.

A cost effective upgrade would be a rear end with a larger ratio. This helps acceleration but at the expense of higher RPM on the highway.
