that sounds like a plan, on that 64 are you planning on a t4 or a t3 foot?

$$ and size ( which affects spool) .... your stock manifold and charger have a t3 foot the t4 is the next size bigger. The t4 will flow better and is cheeper than a t3 charger but it is non gated and will spool slower.

that comes in a wastegated t3 also does not have the 71 turbine wheel, the super phatshaft series comes with the 71 wheel in a WG t3 housing.

Let me ask you this..... What would be the best ultimate setup on that 64 so that it would be best in the twin setup with the s478. I assume the 71 mm wheel would be best and i guess a wg is necessary (Also your thoughts on a BD turbo guard blow off valve) . Also off topic what injectors would you recommend for this setup? I was kinda thinking that 5x0.018 (DDP comp injectors are that size are they not?)with supporting pump work would be enough for 1000 hp but feel free to suggest a difference route. Again off topic, is it bad to have really big injectors and then under fuel them by detuning the pump untill i can afford that s478? If you havent noticed my theme kinda is a high hp build with high quality parts that build on each other. I just hate having to buy stuff twice... Its a PITA trying to figure out the best order to get stuff......... So far my next move is a clutch, then a body job(damn rust!), and then my smaller turbo and injectors.

man the HUGE problem your going to run into is that a medium size single requires a totally different tuned engine to run correctly vrs a medium single and a big primary mate. your gonna have to make a sacrifice or save up and do it all at once. there is just to big of a jump to recommend parts that will work -well- in these two, WAY DIFFERENT situations

Expand on that for me. More specific if possible.
