Here's what I did:
1991 NSX purchased with 100K on it and in need of:
-LR wheel bearing (DDozier fixed)
-cam seels/VTEC gaskets (DDozier)
-oil pan gasket (DDozier)
-transmission mount (DDozier)
-new tires
-clutch master (Did myself, what a BITCH!)
-fuel filter (Did myself, remember to plug the fuel pump voltage regulator back in when your done!)
So got all of that done so I could drive it around and show off, then it was time to get serious about going to the track:
-Baffled oil pan (DDozier)
-Koyo aluminum racing radiator and all 6 hoses replaced with silicone racing grade hoses (DDozier)
-Stainless brake lines/HAWK HT10 pads/blank rotors/MOTUL (Me)
-Recaro SPG/SOS sliding rail (Me)
-MOMO monte carlo wheel with detachable hub (Me - get an alignment when your done because the wheel will not be straight)
-ditch the easy stuff for weight (spare/tools/jack/pump/engine cover)
-KW V3 (Me - bought new from COZ)
-TSW wheels 17/18
-NTO1's 235/275
-CL65Captians old splitter (Me and CL Captain - that was the type of bonding experience in which both your GF's are mad at you because you said it would take 2 hrs and its all of a sudden 630 on Sat night)
-Kognintion 2D rear wing (72" version of illwillems) (Me)
-Comptech "CT" front camber bushings (Aaron Leichty The Winning Formula)
-Solid rear toe links (ET tuning)
-Test pipes (already had Comptech headers and Taitec exhaust) (ET Tuning)
So, without the Aero and the test pipes I had a 2900lb. 260whp NA1 NSX that was good for a win in NASA TTB in my region (on a track I had never driven to boot!). I was proud of that but still not happy as TTC S2000's were still faster, albeit on R6/A6's, but still I knew I wasn't done developing this car. I still have at least 150lb.s to strip (no ABS, no AC, no stero) and I'm still testing to find optimal ride height and alignment for my driving style. Beam bushings are slated to go in this winter along with some other work - I just got done with a practice day at my home track to test the aero improvements and I can say (as usual) Billy Johnson is right as I was exactly 2 seconds faster with wing and splitter...had more width on the rear tires too which didn't hurt but I'm in love with the rear wing on this car. Unfortunately 3rd gear syncro went bye bye on the 3rd session - still shifts fine as long as your not on the track at redline out of 2nd up to 3rd :-(
Here's what you will like:
Supreme bang for the buck in its price range, you cannot find a chassis this stiff in another production car without spending mucho $$$$$, basically everything DDozier says - he knows a little bit about tracking these cars ;-), you'll swear they make more than 270-290 crank hp when your out there, you will have one of the sexiest cars on the track and if you can drive it makes it all worth it, support from the NSXprime track community is the best out there, the steering feel, the "hunkered down meaty" feel of the chassis through the corner, passing newer "better" cars
, etc...
What you won't like:
The 5 spd gear ratios and final in the NA1 US spec cars are aweful, really - a real performance hindrance for these cars, SERIOUSLY what was Honda thinking? Antiquated ABS or "ALB" system on NA1's is not worth having, or rather, pull the fuse and disable it and you will like the stock brake system much better if you are accustomed to no ABS, parts are $$$$, you occasionally ponder why you are turning this piece of automotive genius with a pedigree tracing back to Honda's 5 Formula 1 World Championships from 86-91 as well as Ayrton Senna as lead development driver, Bobby Rahal, and Satoru Nakajima into your track toy? Finding someone to work on it for the stuff you can't do - not a problem for me as I live in the same town as DDozier.
