You could always do something similar to what I've done on my MR30 Skyline (brief list):
Stock L28E (pulled down when purchased with 220000km use)
Rebuilt with new rings/bearings & honed block - it was like new inside, no corrosion anywhere...
N42 head & stock compression (8.39:1). Enlarge the chambers for better detonation resistance & the ability to run more boost.
E15ET (N12 ET Turbo) injectors in stock manifold
VG30 'T3' turbo, with T4 compressor & enlarged turbine outlet (stick with a stock T3 to save cash)
Cast J-pipe on stock NA exhaust manifold (get decent manifold for more HP & more cash).
Stock fuel pump
Malpassi adjustable FPR
2L Supra-turbo (Nippondenso) intercooler
custom distributor (locked w/hall-effect) - use locked standard distributor with reluctor-compatible ECU to save $$.
Haltech E6A fuel/ignition computer.
Modified 4-speed auto 'box (or use stock manual)
3.54 R180 diff (changed from 3.90:1)
Approx 180kW at the engine (125kW at the wheels) at ~6psi boost. Bear in mind that an L28E is ~110kW in stock trim....
~12L per 100km & daily driven (~400km/week) for 2 1/2 years.
And approaching the 270,000km service within the next month.
JCR haven't actually 'done' any supercharger kitst for quite some time & I don't think the cartech kit is available any more either.
Surely there's a wrecked R34GT-R nearby that you could borrow the drivetrain from... <img src="http://www.zclub.net/iB_html/non-cgi/emoticons/biggrin.gif" border="0" valign="absmiddle" alt='
