I have 2005 gen 1 busa with 50,000 miles on it, my plans are to rebuild the motor with new rods,crankshaft lightened and balanced, transmission back cut with a bigger output shaft. the turbo kit I was thinking about is a rcc stage 2 turbo kit. the main goal is to have a reliable turbo bike that runs on 93 pump gas, what parts are overlooked when considering building a turbo bike such as electronics, controllers or to run bigger valves or to port the cylinder head and when should the pros take over on the bike rebuild ?
The real question is what are your power goals? Yes you said you want a bike that runs reliably on pump gas, and that's easy depending on what your power goals are.
If it's not a max effort build, porting the head, and oversized valves aren't going to give you much bang for the buck, specially under 500hp. Hell we've had stock head and cam bikes well over 600hp. Balancing the crankshaft isn't going to be much benefit either. On a street bike that isn't gonna live it's life at 12k rpm there's money better spent other places.
If you're doing rods you're better off also doing pistons. Good head, and main studs are also strongly suggested. You'll need a base spacer with turbo pistons, along with hd valve springs, and adjustable cam gears. Back cutting the trans is a must, along with a hd output shaft being that it's a gen 1.
With a stage 2 turbo kit you can run a maximum of about 420hp non innercooled. However without race fuel or 93 and meth, you won't see that hp on straight pump fuel. Another option would be e85 and some meth would get you there too, but it would be worth getting the 1000cc secondary injectors to make sure you have enough fuel.
Now take that stage 2 kit and add a intercooler, you can make 420hp on pump fuel.
We run the aem failsafe on everything that comes out of our shop. For the money spent you get a wideband, boostgauge, and datalogging. Good valve for a wideband that reads on point with our extremely expensive laboratory grade NGK set up on our dyno.
I wouldn't waste money on tbolt clamps as if you buy an Rcc kit, the clamps are sufficient for stupid amounts of boost.
If you're not very handy we also like to use the ams-2000 as we can set 5 different boost settings. Just turn the knob, and go gap your buddies on the freeway.
We can set you up with everything you need for your goals, and if you're close to Houston, we can also do the build, and tune. If you're not close to Houston we can assist you with shipping your bike down like 70% of our customers do. It's all up to you.
