I've been meaning to create this post for a while now. A little back story...
ever since the BBSC came out like 10+ years ago and I was just a lurker on prime, I wanted to put one on my NSX whenever I eventually got one. As time has moved on I realize many other options have come to the market, which is great, but I still really liked the setup of the BBSC and felt like it provided the best bang for the buck.
Finally after owning my car for 5 years and having bought and sold a BBSC kit to onestepx before I could even install it due to the insanity of '08, it was time to go for it again.
Moving ahead to last year.... I purchased a Novi 2000 kit from member OddJob with the AEM included in January who moved on to a turbo kit. From there I started collecting everything I would need to complete the install. Having researched this setup for so long, I knew exactly what I needed.
As you can see it made for one great looking table in my garage....

Here is my engine bay before...last pic NA.....

From there the install began...The first step was to upgrade the fuel pump to a Walbro 255. Not a fun step, possibly one of the most difficult of the whole install, but got it done.
Here is the fuel tank out....

And the stock and new fuel pump. It is funny how the walbro is much smaller than the stock unit....
DSCF3282 by blodi
The Walbro ready to go in.....
DSCF3285 by blodi
With that out of the way, I installed the rest of the fuel system upgrades...
B&M fuel pressure gauge....
DSCF3287 by blodi
AEM Fuel Pressure Regulator...
DSCF3292 by blodi
DSCF3293 by blodi
RC 550cc injectors (I upgraded these from the 440's that I got with the kit, thanks to onestepx for them)....
DSCF3290 by blodi
I test started the car at this point to check for proper fuel pressure and check for leaks. It did run, though not too happily with the stock ECU in place :wink:
Next I moved on to the spark plugs. Iridium 7's....
DSCF3298 by blodi
I also installed a SOS oil pressure sensor upgrade while I was starting to pull out the airbox anyways to make room for the supercharger down the road.
Next up I installed the AEM unit, a bit more on this later ....
DSCF3300 by blodi
Now it was on to the header installation since I still had my stock units. I went with the Topspeed headers. This was time consuming, but due to some great DIY write ups here, straight forward.
Old headers out...
DSCF3307 by blodi
Obligatory stock vs. aftermarket header pic....
DSCF3314 by blodi
While I had the headers out. I also installed the oil pan that came with the BBSC kit luckily enough so I didn't have to modify my original for the oil return line from the supercharger....I had a local shop weld in the SOS baffle for good measure since I had it out....also hit it with a fresh coat of paint on the outside.
DSCF3321 by blodi
New headers and oil pan in place....
DSCF3332 by blodi
Next was one of the scariest parts of the install: replacing the crank pulley. The bolt is torqued down extremely hard....here is my setup (while tightening it back down.) Pretty crazy eh? It sound like a shotgun going off when you finally break the bolt loose and you'll swear you've broken it, but you haven't.
DSCF3345 by blodi
Here is the crank bolt out.
DSCF3344 by blodi
Here is the new crank pulley in place and while I was in the area, I fitted the T fitting for the oil feed to the supercharger....
DSCF3346 by blodi
Finally I am to the point of installing the supercharger kit itself...which in the end proved to be the simplest part.
Before I installed the supercharger I had a local shop install new bearings for me on the driveshaft for the supercharger. I took a different route than the normal setup. Instead of using an open bearing and seal on each side. I used a sealed bearing that is rated for high speed and high temp. So a bit of a gamble, but much cheaper for the bearings than the standard setup and much simpler....

DSCF3352 by blodi
DSCF3353 by blodi
I also painted the shaft housing and coolant tank black. I'm just not into a bunch of bling in my engine bay. I also replaced the original hex bolts with stainless steel ones as I've heard of these rusting into place and being a total pain down the road when its time to change the bearings again, plus, they just look nice.
DSCF3306 by blodi, on Flickr
Next was installing the coolant tank which requires drilling into the firewall.
Then installed an oil catch can for good measure as well. Next it was on to installing the supercharger bracket. Pretty straight forward if you follow the instructions as far as moving things out of the way, you also have to trim one of the main coolant lines....
DSCF3337 by blodi
Then finally the big moment, the supercharger itself goes in.....
DSCF3349 by blodi
Hooked up the oil lines and that set was done.
Next I put the drive shaft into place. I installed a new green spyder gear that goes between the shaft and supercharger since these are known to wear out.
DSCF3363 by blodi
Next was installing the AEM Meth/Water Injection kit and my gauges on the interior. This was a lot of time doing wiring as you can see. I used the SOS a pillar setup to mount my two gauges...(boost and air/fuel ratio)
DSCF3367 by blodi
DSCF3368 by blodi
Meth Injection installed using the SOS mounting plate. I had to heat up and push down the top of the meth tank to get the trunk to close properly.
DSCF3371 by blodi
Finally, it was just down to hooking up the intake between the supercharger and throttle body. I had a local shop weld on a bung for the meth injection nozzle here. And then I put on the supercharger intake. I opted to go with a few parts I order from Spectre for an intake instead of the one that comes with the kit. I got a heat shield to hopefully keep intake temps down a bit and I also kept my downforce intake scoop in place to direct cool air directly at the air filter....
DSCF3376 by blodi
A few more pics of the final product....

DSCF3401-1 by blodi
Beyond this I went ahead and installed dual AEM wideband sensors for tuning and SOS test pipes. I already have a custom flowmaster exhaust setup in place.
So with everything in place and about 60-80 hrs worth of install time it was time for tuning, so I called a long time friend of mine who goes by Garage99 to do the installing. He mainly does Subaru tuning but did a great job tuning it on the street over the next few weeks little by little. We also had Devin at AEM to chime in whenever we ran into a question....
The car was a blast to drive, really fun when the boost comes on and sounds like a jet engine it behind your head when you are driving around. The pulley that came with the kit which was an unknown to me at the time was pushing 9.8lbs at redline, more than I really was hoping for, but we've tuned it very conservatively.
Finally it was time to go to the Dyno....and the results....334rwhp :frown:
and that was up from 307 on the first run with the tuning. I was expecting at least 400.
So I was certainly disappointed. Another thing that was bugging me was that my widebands were a full point off at higher rpms. Finally after seriously weeks of scratching our heads and trying different things (swapping injectors, swapping widebands) I rechecked the vtec connector to the AEM....I had the connector for the rear bank one pin off!!! The newer AEM has a better/more OEM design for this now, but I finally got the connections right. What a difference! Car pulled much harder and more eagerly to redline, idled better, didn't surge when warming up, the widebands were now reading correctly...etc...boy, I felt like an idiot.
So that brings us to now a year later and about 3K on the setup. Its running great still. The stock clutch is finally starting to give up and I'll be installing an upgraded one this spring. I also am planning on doing the SOS VVIS delete and SOS big bore throttle body. I also am thinking about going to 100% meth instead of the 50/50 mix I am running now.
I still haven't gotten back to the dyno since the vtec correction, but am sure I'm hitting an easy 400+ at the wheels. I'll put it this way, a local F430 didn't fare well against it.
I'll update this thread once all of that is done. I am hoping after I had the new parts to have Cody (Lovefab) put a spit shine on the tune for me and we'll see how she does.
Sorry this was long, but I've been putting it off for waaay to long! Overall I am really really please with my setup and can't wait to enjoy it more in the spring. There are some great turbo kits out there, and if I could justify the cost I'd easily have gone with one. But this has been a great bang for the buck.
Here is my current setup:
91 Red/Black 5 spd.
-BBSC Novi 2000-10lbs boost
-Spectre Intake
-Downforce Intake Scoop
-AEM Meth/Water Injection Kit
-Walbro 255 Fuel Pump
-RC Engineering 550cc Injectors
-AEM Adjustable FPR
-B&M Fuel Pressure Gauge
-VVIS disabled
-AEM UEGO Dual Inline Widebands
-TopSpeed Headers
-SOS Test Pipes
-Custom Flowmaster exhaust
-SOS Oil Pan Baffle
-Prospeed Boost/AFR Gauges
Here are a few vids of the process...
The first start with the blower in place....sorry, I sound like an idiot, I was really excited....

<iframe width="420" height="315" src="http://www.youtube.com/embed/B12e_jme1Kg" frameborder="0" allowfullscreen></iframe>
And finally...a great video that one of our local enthusiast put together for me of my first track day ever with the car in Sept. at Waterford Hills...
