Hi there ,i had my trusty s14a with sr20de engine head gasket blown along the radiator too...

Since i am going to sent the cylinder head to a cnc shop for machining for a perfect fit what else can i do to improve the engine ?

And please don't mention why bother with a sr20de engine as i have another silvia were i swapped a s13 redtop....

I just want to fix the car for reliable daily use but if possible without spending a fortune improve the power a little bit.

I heard about cylinder head boring but does it worth the extra cnc shop labour cost ?

new higher compression pistons are too expensive

Do pulleys improve the engine at all ? And if they worth the money which to choose ? Most i found on ebay say they are for 240sx and some say they need some work to fit on a s14 with a sr20 de/det . Please explain to me ....

And last about an cold air intake .Does it do anything and if it does what to choose ? Most i found on ebay say they fit 240sx ....Intakes specifically for a sr20de i did not find anywhere...
