i bought a 93 hatch for 1500 bucks...had an ls swap with a 20g mitsubishi turbo on it..manifold looks to be in good condition...all oil lines were ran and capped..everything looks good...only problem is..the guy that had it before me had some ghetto fabbed intercooler piping,and his intercooler looks like a sidemount off a old ass car...(one of the short stocky ones)..now i talked to my friend at the shop..and he said hes gonna go thru all the wiring,and finish everything up..and he said until i get some type of Fuel/engine management,that 4 or 5lbs of boost would be fine...but i have some questions : 1. the intercooler piping came with no type of relief/blow off valve to let out the excess boost...now ive heard that running a turbo car with no blow off is not reccommended...is this true? and what can i do in the mean time instead of buying a expensive BOV? 2. With no fuel or engine management (YET)...what am i looking at as far as driveability...and am gonna be in a "you cant drive it yet until u get some type of management"..or am i looking at "you will be alright as long as you keep the boost low" type of statement keep in mind,i am no turbo guru...i know how they work,and a general knowledge of what is needed..but i just got this car..and its itching the hell out of me to drive it (i wanna see what i paid 1500 dollars for,wouldnt you??)...plus its my first boosted car...i mean i wanna do it right the first time,but i also want to drive it...anyone got any advice?
