This thread is outrageous!
How dare you come on here, with your common-sense attitude to an FI build, getting all the important stuff beforehand, and having a well sorted plan of action rather than just throwing money and hoping for the best! Scandalous!
Top work fella, I wish you the best. I'd consider doing the brakes too as a supporting mod. I may not bother with an engine build unless you are looking for silly power, too.
The only thing I will say is that by the time you've completed this you'll have spent what, £3k on support mods, £5k on an engine build, another £5k on the s/c kit: That's nearly £15K, plus the value of your car at say £5k, so that's £20k which would go a long way towards your dream of a GT-R. As exciting as your project would be, is it as exciting as living a dream? I'm not sure. Just a thought though.
