i have 98 M3 with 83k. looking to do a tune up on some things.

wanted to do plugs, whats a good plug to go with?

what are some other things i should do? i did repalce the air filter just recently with a K&N drop in.

anyone know of any cheap or free cometic/performance tricks??

getting a little itchy with the car and wanting to work on it some

 

possibly replace my fuel pump too?

 

I wouldnt replace the pump unless your having issues with it, but def do the filter.

and about your other thread with the 3.5MAF it will work and fit in your car, but you need software programmed for it.

 

got any hookups for some software?

 

Negatives on hook ups....but I always liked turners software.

 

wat all u got done on ur m3 now?

 

NGK spark plugs and wires
maybe find some chipped ECU somewhere?
look at DINAN and maybe you can find some other company that will be similar to what they do

 

you sir need to swap to the old style intake manifold from the m50/s50 (e36 325i, 95 m3) as it is has much larger runners and will probably give you 10hp without any kind of tune or anything else. you can get this used from many many people on bimmerforums.com or even from a junkyard.

if youre looking for a simple drop in chip you'll need to convert your motor and ecu from OBD II to OBD I stuff from the earlier 24v motors. your obd II system would have to be reflashed (still easily done by turner or any of the others). lots of people convert to OBD I as it is simpler and considered better.

your s50b32 is a beast waiting to come out. just spend time researching on bfc.com, theres more info to be had there than you can handle. if you need any bmw help hit me up its pretty much my thing
