ok, foreal.
Get a ka motor. buy a cometic headgasket and ARP headstuds. Get the head decked and instally the headgasket and arp head studs correctly.
Get an ISIS turbo manifold, and a small ISIS turbo.
get some 550cc injectors, a z32 mafs, walbro pump, and an enthalpy tune.
ISIS intercooler kit and oil/waterline kit.
Put that shit on there and make 300-325 and it will be super sweet.
anyone talking about getting a car to the track on a budget should reconsider what they want to do. on a budget isnt spending 2 grand on the engine alone.....
as far as sr vs ka, there are thousands of threads and articles online
my two cents is an sr was made for the 240 (silvia in japan) and the ka was made as a truck engine. when 240s where introduced into america some idoits decided a boosted sr was too potent and gave us a truck motor instead.
but then again ppl call me crazy
KA-T done right between the two
