Cheap/Basic M42 Mods.

I think the exhaust on the M42 is already stock at 2 1/4 you should jump up to 2 1/2 a better cat and muffter setup. The summit racing turbo muffler sounds awsome on the M42's. My buddy had a MarkD chip on his M42 and it made a big big improvment. Its pretty much the best bang for your buck.

mark D / WAR chip are the two best

Intake Is not so much a mod UNLESS you go Headling intake which DOES improve the car. Superspring/ REMUS/ Stromung or GTFO

Regrind Cams are an option for 300 bucks

m20 flywheel is a cheap option too for performance.

Or get a Supra motor?

What is out there?
I've done some searches, but I want to see what could happen first-with a budget.

The car at hand is a 1991 Bmw 318i 4d. (m42 as yall know)

I've been reading about chipping, which is the best, and provides the best hp gain? also, exhaust, intake, etc.

This is a highschool/d.d/fun car that I'm working on getting all together so I can retire the Peugeot to a weekend/occasion car.
