Ok so long story short i have a 1995 gsr swap which i am turboing. engine is bone stock except for a lightweight flywheel and an itr throttle body.

my goal is 400 WHP. So far i have a Tial 50mm BOV and a Tial 38mm wastegate. i already have an intercooler and all the piping, and ill be tuned on S300 once it all goes together.... i have 2 questions....

I pretty much decided on using a GT30R with a .63 exhaust housing based on all my research. Is this a good choice for my goals or is it overkill? or should i be looking at something even bigger? or perhaps a different type of turbo all together??

Second question is injector sizing. are 750cc injectors going to be ok or should i bump up to 1000cc injectors? any disadvantage to running injectors that are larger than i need?

The smaller the injectors as a roule of thumb the better the spray pattern and that means engine respons and great idle etc.. 750cc should work.. I see no reason not to go with ID injectors.. I have done a ton of serching the net for info on wht injectors that have better spray patterns and fuel atomisation but ID injectors are the only ones that even mention that stuff and they are proven to better than the usuaöl comen injector.. GT30r is a great turbo for what you are looking for.. It has a killer respons on a streetcar can reach up to 500 hp but will last longer on a 400hp car not pressing the turbo..
