Turbo set-up to get power:weight of RSX Type S

[Carvin'07]

Hi all,

So, I am at a crossroads. I would love to build up the Yaris and have the thousands to do it, but am torn as to whether I should throw in the towel and just buy an A4 quatrro. You see, last week I drove a friend's 2005 type S and was incredibly surprised by the power. I used to drive a high 13 sec AWD DSM, so I wasn't expecting as much as it put out!!!

I'm fairly sure that the yaris can be much quicker and 'different' with the same amount of cash invested as getting the A4 (~17,000 cdn, with the Yaris selling about $10,500 privately, leaving a theoretical budget of $6,500).

Edit: added ratios
RSX-S power:weight = 210 chp : 2840 lbs = 0.074 hp/lb
Yaris would need to be 166 chp : 2250 lbs = 0.074 hp/lb

Here is my list...what am I missing?? Are the prices realistic?
clutch $300
flywheel $300
LSD $1000
-These three I figure I can leave until I make more boost, although I really am lusting for the KAAZ 1.5 way If I did the lsd, I would do the other two at the same time.

Do I need to get e-Manage to do the following? Further, do I even need e-Manage to run low boost?
-add MAP sensor from JUN Japan, 'clamped MAF' via e-Manage, can also 'clamp' stock narrowband O2

Turbo choices - I don't want to make a ton of power, but would like it to spool up at least 3 or 4 psi by 3500-3700 rpm. I would be very happy with 150 whp in this little egg $800 - 1100 is what I would be prepared to spend:

k03 <-- does anyone recommend this?
14b <-- small, but capable, plentiful in DSM world
T25 <-- tiny, but possibly good for the little engine? Lots available from DSMs
small 16g <-- likely a good, cheap and quick spooling turbo
big 16G <-- up to 320 hp, too much for me
GT20 (makes 143 PS; <3,000rpm to full 8psi)
GT2554R - more power than RS6 turbos and with quicker spool
GT 2876 (GT25) $1100 USD... up to 460hp <-- too much power for me
GT 2860RS disco potato DBB PN 739548-5 .64 AR ...$1150 USD 250-360hp
$1000 <-- also too much power for me

exhaust manifold -- does anyone produce them, or does everyone get one-offs??? custom $500?
return line for fuel to tank - $200?

Wastegate - change spring to run lower boost?
BOV needed?? $300
I will run no IC as I plan on a max of 6 psi
only need filter to turbo inlet piping - custom mandrel bent $150

injectors
1zz
2zz
TC
$180

cheap copper plugs, 1 or 2 steps colder until I dial in optimal set up...
then install iridiums at the best range - $200 for 4 sets of copper, 1 set of iridium

WBO2 is a MUST for me - $450

What did I miss? Thank you all in advance for helping out.
