DeaconFrost,
1st thg's 1st....d current workshop whr ur car is in now,they r not familiar w a B20Vtec build or u think they r quoting u very expensive price?if it's either 1 of 'em or worst,BOTH,i won care much....might as well tow d car away 2 sum1 who knows dis kinda build w a reasonable charges rather thn suffer/regret la8......
n since u say d car has no engine(wat abt interior/wiring loom/ECU?)...it won b cheap....stock B20 bottom can go 4 as low as 800 right up to 2000...depend on market n who u know....n u'll need a DOHC VTEC head....cheapest wud b 1.5K 4 a stock B16A head(i think).....or try 2 go 2 Samurai Racing in Sunway...i know they haf alot of engine kosong lying on d floor....even a few complete Type R head..if u can afford dis,it'll b better......so,i'd say a budget of ard 5-6K is d ballpark figure 2 get a reasonably reliable B20VTEC...
gd luck
