    RYU's "properly molested" NSX build thread

    After 8yrs of ownership and nearly 2 decades of idolizing the NSX I realized this year that i'm nearly done with building the perfect supercar for me. Building a Type R would have been cool but if I couldn't have a real Type R (complete with blueprinted, balanced NA motor, etc) it just wouldn't be a Type R, Yet I wanted to stay true to what a type R really is; an exercise in balance and engineering. I also wanted a comfortable car which some say a Type R is not. This mantra helped me determine I wanted the lightest NSX possible but still maintain the creature comforts of a street car. I wanted to stay under 400wHP yet build a car that is easy to drive FAST. This goal helped me select my suspension, brakes, gear set, power adders, and maintain the overall direction of the build. Through many trial and errors, never before built on an NSX custom parts, and countless late nights spent in the garage I think I'm finally happy.

    Over the next few months i'll document the different stages of proper molestation that my NSX was subject to. I'll try to post a portion of the build every few weeks and describe my rationale and goal for each modification.

    Mission Statement: To build a streetable and versatile supercar in which longevity, value, and quality engineering determined the proper combination of parts, whereby the parts together are more than the sum of their individual pieces.

    Spending time at the track this weekend with fellow NSX bretheren made me realize i'm almost done. I can finally drive the piss out of this thing and not think twice until the next time it breaks

    Congrats on such a great build. Simple, properly functional and beautiful. They say that these projects never end, but I understand having an ultimate vision and goal where you near satisfaction. Your pursuit has driven you to explore beyond most others, and this is truly commendable. Well done, mon frere.

    People know I have the highest respect for Steven's products. However, the iLift is the Mercedes of lift kits. Alternatively, I'm happy with my Honda Though one day, I might be able to afford a Mercedes. Steven's iLift makes other lift kits (the one most popular here on Prime) look like a Yugo though.

    Hi,

    after your text introduction on you goals, i'm very curious to see in images your path to get there... congrats.

    can you show a photo of your radiator (MASiV) ??

    thanks,

    Hello Nuno,

    The MASiV radiator is a heat exchanger i've helped developed for the last 3years. Jim (Coz) has been gracious enough to race with a prototype this season in his 600wHP, intercooled, laminova oil cooled, fully built race car. Jim is a great guy on and off the track btw. Can't say enough about him. After so much development we finally found a formula that works amazing in the NSX and it fits 100% like stock. Just imagine, Jim was running a thick 3-4" Ron Davis radiator core that was much thicker than stock and the MASiV radiator performed BETTER. We also have reason to believe (from local data as of last month) that the MASiV radiator is performing better than the PWR unit with the integrated oil cooler. I have tons of respect of Ron Davis as a company and heaps of respect for our Aussie PWR friends (they make F1 and basically most motorsports coolers you see on real race cars) yet the MASiV radiator is better (at least on the NSX). For example, in hot and dry Arizona weather, average ECT track temps on Jim's car was 215F with the big Ron Davis. He's now seeing average temps of no higher than 205F. A local friend is also using a new PWR radiator. It maxed at oil-239, max water-213 on an NA 3.2L. I've been testing this radiator with the OEM fan (Jim is using twin Spal fans). Our NSX OEM fan is so crappy it's incredible yet the rad is to be so efficient the OEM fan is adequate. It worked fine during cool down sessions at Buttonwillow this weekend albeit it was only 78F ambient. Regardless, I was seeing ECT track temps no higher than 77-82C and my car is supercharged. Pretty amazing.

    I've asked the company to do a Group Buy here but the intent was to develop the fin technology with sales to the NSX market as secondary. I think with Coz Motorsports helping with the sales they'll do a small run for us. Not quite sure how many folks on here are even interested in a high quality radiator though.

    Nice to see you're making a thread.

    Could you tell me a little more on the AS Motorsports phenolic gaskets for the intake manifold and CTSC and how the install worked out?
    Did you notice any difference in the AIT already? I'm going to get my manifold gaskets installed next week and the IAT sensors installed and am curious about your findings so far.

    I am. I also have twin Spal fans but would like a better radiator.

    Glad to see you on track! Jim's a great guy and is a great platform to test the radiator with high demands of a fast turbo car that actually races. Great to hear that your radiator outperformed a heavier Ron Davis.

    Who had the PWR radiator and did they have proper ducting to a vented hood like on Jim's car?

    For the NSX, i'm not a big fan of integrated oil coolers (in the rad). Unless the car is dry sumped or has a higher volume pump, sending pressurized oil all the way to the front of the car isn't ideal. Also, the integrated cooler injects a TON of heat into the radiator which takes away from the cooling ability of the coolant, while not always lowering the oil temps as well as a proper stand-alone air to oil cooler (although 239*F isn't bad atall so it must be cooling the oil pretty well at the expense of water temps).

    Were the temp numbers (Jim's Ron vs. yours and the PWR) on the same day or temperature within 10*F?

    9doors (Nick) has the PWR. Nick E. put it in for him I think. there is a pix floating around here by 9doors. A few months ago I saw the car, I don't remember he had ducting or a vented hood. I could be wrong by now.

    Oh....one more thing Regan....ok, no lift kit, I think you should get a Giken.....its not ricey and nobody can see it.....its worth at least a second.
