Squeezing more power?

[alilegendw115]

Hello people I own a 1975 mercedes w115 230.4, I know it's not built to be a power house but is there any cheap and cheerful performance mods I can do to help the engine run better and/or even squeeze abit more power out?

Thanks

If it's petrol make sure all the ignition is in tip top order

Depends how stuck in you want to get. Take inlet and exhaust off and take a die grinder to the ports. Change cams? In our mi16 we've got two exhaust cams for more torque. You could run some injector cleaner, also use high octane fuel. Fit a higher pressure fuel pump. Wrap the exhaust, fit a bigger bore exhaust.

I did a few bits to my Mercedes 200 engine years ago, but really you're not going to get huge gains from any mod that's cost-effective. If you're happy to do it for fun without any high expectations as I did, then fair enough.

Bear in mind that there are no bolt-on performance bits for this engine so everything would need to be adapted. I fitted a K&N air filter, replaced viscous fan with electric, and put a free-flowing exhaust on mine. It sounded sportier, and the electric fan meant it revved a bit snappier, but really the performance improvements were marginal. I put it on the dyno for a laugh and it did put out a few more bhp than standard, but only 10 or so.

Once you're getting into ported heads, performance carbs and other stuff that costs proper money, you'd probably get more bang for your buck with some sort of engine conversion although none of it will be cheap!

Yep, but not cheap.
