will cost so much bro, i drop in 4G67 engine & pass with it , thn mod everythings to VR4 cos 4G67 block is non turbo type as u known... i suggest u to drop in 4G61 1.6 engine , thn upgrade to 2.2 kit. much more better & safety.hahaha... this is what we call as boleh land lor....
mine also the same.. have 4g67 block standby already.. once $$$ dry liao then.... say bye bye to my 4g93na...
by the way.. how ur 4g67?? bore it ok or not?? my plan also the same as urs...
Or .... another better way is selling ur car & buy my car lah, no modifying needed...
