Well I thought Id start my NSX build thread considering we are assembling the engine next weekend.
In my spare time while waiting for the AEBS-sleeved block to arrive, I have been plugging away at whatever I could complete from fixtures made in the past 12 months of NSX-boosting - to get as close to finished with the turbo setup as possible - without the engine in the car.

Setup:
95 Acura NSX, 110,000 miles.
Comptech 4.55 FD(came in the car);
Exedy Hyper Twin Plate clutch(Thanks Exedy!);
AEM EMS; with MSL OBD2 conversion harness(allows the stock DBW system to function);
RC 750cc injectors;
Walbro Pump;
AEM FPR;
Sleeved block;
Wiseco Pistons;
Oliver Titanium rods;
REV valves, springs, retainers;
GT4067 turbo;
Custom WAIC intercooler - twin-core, good to around 1600whp;
Comptech headers, LoveFab Secondaries;
TiAL pressure relievers.

Thats basically it for the setup; stock axles and tranny internals, so anything much over 500whp and the tranny will chew itself up. However, Id like to turn up the wick to around 700whp; should happen under 20psi.

Now the pictures!









Slightly smaller turbo, similarly built motor, 15psi on another NSX. Same basic rest of the setup:


My stock NSX motor, 106,000 miles at the time of dyno charts. Dynapack, reads 10% higher than a Mustang(what I prefer) based on our dyno testing results below. Reported boost was 8psi...


We confirmed three different brands of local dynos this spring as well.
Each run was made under the same weather conditions with reported boost averaging 7.5 psi and no changes to the calibration. The tested car was a 2004 NSX with the MSL OBDII AEM solution and Lovefab single turbo kit.

Here are the numbers:

Mustang Dyno (Payn Tech)...................395.6 HP / 308.9 TQ (SAE)
Dynojet (Advanced Chassis Dyno)..........402.3 HP / 318.8 TQ (SAE)
Dynapak (Godspeed)............................438.2 HP / 324.3 TQ (SAE)

Stay tuned, Ill have more fun information, pictures, and charts as time progresses

how are you going to run a filter on that turbo?? It is going to pick up a lot of road debris being under the back of the car like that.....

SICK SETUP!!! I cant wait to see this the progress....

 

we run the filter way up in the quarter panel; just not pictured here for cool "pictures".

Im running Oliver rods (not titanuim though) in my starion racecar they are beefy as fvck

 

These are quite a bit lighter than the stock titanium rods(in rod/piston combo anyway); but they are 3X as strong. My bottom end has been confirmed over 1500whp in another NSX engine.

 

Cool.

Whats the DBW system? Pardon my ingnorance, I've yet to work on one of these masterpieces of a car

Yeah I did alot of research before I went with Wiseco Pistons I talk with one of their engineers Brian Nutter alot and came up with my custom piston set-up

DBW= Drive By Wire.
1995 and newer, all NSX's are DBW. AEM doesnt build any DBW computers, so an adapter harness is utilized so that the stock ECU controls only the DBW system, leaving the EMS to control everything else.

 

I wanna see more.

I can only imagine ripping one of these cars.

 

So you're also using modified headers. Is there any particular reason why you didn't completely make an exhaust manifold. Just wondering, since I know FX does the same.

 

Looking good cody

 

nice build up

good luck with the project

 

I bet that will be really nice. Sell it to me. I'll come and get it in Feburary.

 

is the waic in the back, whats in the front? i'm confused ;D

 

 

ur bseries manifolds are hotter

look sexay, i love that color nsx..funny thing is, i've been seeing one exactly that color w/ a comptech SC for years, always wanted to race it, but i never saw it driving, always parked...at our local acura dealership rofl

you all the sudden a baller?


and NICE build

 

I was wondering when this thread was going to pop up. Good stuff Cody. I got to tune a boosted NSX this summer.. that car was a BLAST.

 

 

very baller cody! looks badass

 

suscribed btw why did u guys had to bring the intercooler all the way to the front then run the pipes blah blha why not stick it on top of the motor with a custom maded funel/air inlet like those on mr2's but wider ?to fit the intercoole

its got a water to air intercoler what you see in the front is just the heat exchanger (radiator) for the water.

This car will be NASTY!

Unmodified headers; so people that already have headers can basically bolt our system on(if/when we are ready to ship these kits to customers). We actually prefer DC sports headers, but my NSX came with Comptechs already, so might as well use them. I tried a few different custom combinations earlier this spring, but the added cost of building them in-house vs. calling up and ordering a set of headers in two days definately did not out-weigh the performance gains. I may play around a bit, but with VERY limited engine bay space, we are pretty much stuck with this combination.

We use a WAIC mounted rear-ward for shorter charge piping, then plumb water lines to the front of the car to a dual-core heat exchanger; I will probably be anodizing mine to hide it a bit better, but we will see.
Inlet air temps are 20 degrees warmer than ambient air temps in just about EVERY situation; with the single core intercooler. This is our first dual-core, which will be needed for the kind of power we are going to be pushing through this.

Oh, if we peg this turbo and feel there is room for more, something "larger" will be thrown in
