Thanks, yeah I was thinking the end result would be pretty similar if I kept them relatively stock but who knows how long that would last (wink wink). for the 510 I was thinking:
-ka24de
-individual throttle bodies (yes I know this would be a project in itself and I would likely keep it this way for a while until the turbo build started)
-custom intake plenum around itb's
-t25 or t28
-fmic
-370cc injectors
-maybe a n62 maf
-a nice tune on nistune or a piggyback apexi neo, some sort of management
-other mods (exhaust, fuel pump, etc)
-looking for around 250-275whp
I think if I got a reasable tune I would be able to keep the ka alive with the turbo for a while or I could fortify the bottom end and get a better turbo if I'm willing to dish out the cash.
for the z I was thinking:
-rb25det
-injector upgrade if needed
-new turbo manifold
-maybe a gt3076r or t3/t4
-greddy intake mani
-fmic
-a supporting tune
-looking for 350-400whp
Now, I realize the z would be more expensive in the long run, but I simply can't get over how lovely the rb series is. I also have a love for the 510 so I'm hoping someone can help me out here. The ideal scenario is I build one now and build the other someday later in life and live like a fat and happy car admirer, but that's not too realistic. I hope someone can give me a hand, thanks guys.
