Want to iron out a few things.. As I've realised its going to be built, not bought...

97' 180sx Blacktop.

Filter.
Intercooler.
Cat-back.

I want it running sweet before I continue to go forth and drive the shit out of it...

------[few questions below]------

My cars cooling system.. Has...erm.. just water... (added/droped some anti freeze in it there the other night)., but what I want to know is, what is the ideal thing to put in the radiator?....

Which spark plugs should I go for?

I reckon I need a de-cat & downpipe.. Is it worth forking out for an elbow at the same time?

I need a boost up. An AVCR is ideal put so is its price tag.

Eventually I'll try fill it with mobil1 15/50 but thats for later...


ANY INPUT IS REALLY APPRICIATED
