that 2nd turbo you mentioned , i believe is too big on the compressor side for the 194. it will be able to supply too much air and easily overboost the engine.
300 you will probably need to run a turbo like the 1st one i mentioned and also add a external wastegate to keep the boost in check. it will be hard to find a cheap turbo to handle almost 200 ci for the exhaust side . it would be great to find a t3/t4 a/r50 on compressor and .96-1.2 on the exhaust. i just have not seen any. so you could settle for the smaller .63 exh trim and use the bigger wastegate to vent the exhaust. tom
