I guess I haven't done a "build" thread yet, so here goes.
Goals
I would like to build within a reasonable budget, a 300 wHP naturally aspirated 3.0L NSX. I primarily drive the car on weekends, and enjoy "spirited" driving along many different routes here in So Cal.
The Car Itself
I bought "Elsa" last October from tbromley. She is a 1991 silver car that had about 48,000 miles when I bought her. She was in great condition, my only complaint about her were the wheels she came with (TSW Hockenheims). She also came with Comptech headers, an OEM NA2 exhaust system, Dali's "hot chip", Dali's shift light, and the Cantrell AIS.
Modifications (Done)
Installed Bilstein HD shocks on the lowest perch, mated with stock springs.
Installed the NSX-R front chassis bars (upper & lower).
Replaced the Dali "street" front sway bar with the NSX-R sway bar.
Replaced the factory transmission with a 4.23 final drive/JDM short gear-equipped transmission; while I was at it I upgraded the clutch to a Clutchmasters FX200 piece (it came with an aluminum flywheel as well). During the swap I upgraded the transmission mount to a STMPO piece (I am kicking myself for not buying the other mounts before Ross stopped making them altogether).
Installed RDX fuel injectors and had Brian (Prospeed) reprogram my ECU to accept the new injectors. This was a well-documented project.
Installed TiDave's short shifter kit, along with a TWM "M1" weighted shift knob
Installed whiteNSX's HID kit (4300k)
Had the rear hatch, side windows, and front windshield tinted.
I have removed the following:
Planned Modifications for the Short Term
Ported intake manifold, mated to a 74 mm Blox throttle body
Prospeed exhaust system
Prospeed cold-air intake system
Tein RAs
Hawk HPS pads, Stoptech brakelines, Motul 600 fluid, STMPO brake ducts
AEM fuel pressure regulator, Autometer fuel pressure gauge, and re-test the RDX injectors at 60 psi
ATI engine damper
Installation of Autometer 2 5/8" Ultra Lite gauges (water temp., oil pressure)
Volk wheels (16" front/17" rear; TE37s or CE28s will be fine)
Removal of:
Modifications for the Long Term
Ported cylinder heads
Custom newly cast camshafts with 12.0 mm of lift, valvesprings as appropriate
That is all for now. I will update when there is something worthwhile to mention.
