Go the vh45! Was going to do that to my r32 as there is a kit made in the states that fits it to the s13 x member! :) was looking at a blown setup for these bad boys as well and you can easily get 400+hp out of one with small amount of boost to stock unopened motor! All of this will set you back about 6g plus tuning and a donor car!

Also respect the kid what a good driver and well setup car :)
