when serching fora turbo i looked for the most lastest (hopfuly more
advanced), proven reliable turbo that was from a engine with similar
displacement to mine thats how come im looking at the ca18 and sr20. but
every time i look in mag which has old carby cars with custom turbos they
all seem to be using a to3 garrett some use t03/t04 hybird???.
anywa is this a better turbo than the ca18 and sr20???
