Cost depends majorly on mechanic..
The mechanic is the biggest headache in the conversion..
Get an excellent mechanic who keeps his word, and charges for
ONLY what needs to be charged..
10k will get u a Track Ready to whack set.. if u get the right person..
8k should be MAX.. For JUST the EXCELLENT conversion labour charge and halfcut..
of course this is not taking into account the on-going cost..
If done well initially, then On-going cost will be minimal..
Oh and go for sr20deT
get the turbo.. Its worth it ;)
Happy converting :D
