It's time for forced induction. (Long. Skip to end if you wish.)

I've been meticulously modifying my SE-R for four years now, planning
each upgrade with care; balancing the pros and cons. Even so, I've made
a mistake or two along the way despite my attention to detail, but I've
learned from those mistakes. One of the things I've come to learn, is
that while fun, doing things differently than most others with the goal
of obtaining something more "perfect" isn't always the best choice.
I've endured a nine-month-long production and shipping delay on custom
offset Panasport wheels.
I hassled Brian Hasty at Fastbrake Enterprises for a brake rotor hat
some 3 or 4 millimeters taller than normal and matching custom dog-bone
adapter.
I designed custom 12 mm wheel spacers, and paid a premium for them to be
made.
This, all in the effort to fit 11" rotors inside 15" Panasport wheels
without the tire protruding from the fender well. In an effort to keep
things short, let's just say I'm left with a set-up that is less than
ideal, finiky, and costly to repair/replace if needed.
With this in mind, my plans for modifcation have changed drastically
from my original plans. I'll get those up to speed who aren't familiar
with my car.
First, I upgrades the front brakes, and wheels/tires as mentioned above.
Next I moved the battery to the trunk (for weight distribution, and I
anticipated a turbo install that involved relocating the battery). I was
also in on the first group buy for the rear strut tower brace, so I
installed that, a Progress 3-way adjustable rear anti-roll bar, as well
as replacing the front anti-roll bar with the factory XE bar (less stiff).
A long time passed, and I'd been doing random up-keep, fixed the 5th
gear pop-out once it reared it's ugly head around 145k miles... You get
the picture.
Finally, just recently the rear brakes gave out, and I took the
oportunity to upgrade them to the larger Maxima rears.
I've planned from the beginning to do brakes, then suspension, then
power and associated things (like clutch). It's getting to the point
where I have some money to spend, and I've just recently fallen into a
new crowd, one member of which shares my passion for cars. Once again,
in the interest of keeping things as short as possible. I'm ready to
plan the next major modification.
If you've been paying attention, that means coil-overs. A long time ago
I spoke with Scott of ShigSpeed about a coil-over set-up, and he quoted
me $2,100 for what I was looking for. Since then, progress has come
along with a (more affordable, but non-adjuestable) coil-over option for
$1,500. I'm still weighing these options, and I'm not even sure Scott
still does this sort of work anymore.
That's suspension though. That's not what we're hear to talk about.

START HERE IF YOU SKIPPED FROM ABOVE
-----------------------------------------
Here's the old plan I had for forced induction:
Something similar to what the project SE-R Turbo car had at
www.nissanperformancemagazine.com centered around that tubular turbo
exaust manifold. External waste-gate, GTi-R pistons and rods, alcohol
injection (instead of water injection), etc.
The goal was to make 350+ reliable HP, upgrading the clutch, preassure
plate, radiator, and transmission (straight-cut gears possibly, or at
least cryo-treated gears).
I've had some three years to rethink this upgrade. Mike Kijoma's tech
article on wastegates helped convince me that a cast manifold would be
much simplier/reliable. I've also lowered my power goals significantly.
Partially due to my desire for bulletproof reliability, and partially to
lessen the cost. What would have been a $6,000+ upgrade (all said and
done) has turned into something I could concievably do this summer with
$2,000 or so.
I no longer feel the need to hand pick my own intercooler. I don't need
to source my own high-flow fuel pump... I'm ready to just buy a kit and
call it a day. I'm looking to make 225-250 reliable horsepower. Here ar
ethe questions:
Should I just keep my 9:1 factory pistons/rods to keep the throttle
response high and save me the cost of new parts? Can I expect to hit my
power goals without harm to the engine?
What kit would people suggest? I've looked around, and there are
attractively priced Stage I kits for $1,300 or so at at least one place
I know of. That's an extremely attractive price.
I no longer care if I have an external or internal waste-gate. I'm not
really concerned with much of the details anymore. I just want to cure
the turbo fever I've dealt with for so long.
What would you do in my situation?
Maybe buying up the stock components for a SR20DET would get me the
power and reliability I'm looking for?
I apologize for the length. I tried to make it as short as possible.
Apparently I failed. =/
