Hey Guys, I just installed the RaptorPerformance.com Shift Light with Launch Function... I have used this shiftlight on several other types of vehicles, and have always been pleased. On the RB26DETT, I'm having issues. I have wired it up to the ECU, but the light does not light up @ programmed RPM. The wiring is correct at the ECU, and I'm wondering if perhaps the signal is too weak off the ECU...Perhaps I need to wire it in at one of the coils... Just curious to hear your thoughts... Thanks, Chris

Found two "buyers", but neither could get approved for financing....

At 25K, I'm giving it away, which is something I wasn't prepared to do. I may keep it if it doesn't sell this week on Ebay... I didnt want to sell it, but I promised the old lady that we would use the funds for a downpayment on a house. But the house may have to wait, as I have too much wrapped up in this car to throw it away. We'll see...

My girlfriend may be, I'll get back to you, haha.

Let me try this....to the first person that can come up with $25K, I'll hand over the title

I meant that as a figure of speech, haha.

$25K buys it, to the first person with cash in hand.

Yes, but I am willing to have the car tuned for 93 octane at my expense for the buyer...

Just put an offer in on a house

New Katzskin Interior Install: Pacific Blue Suede with Black Leather

Update: Had the car shot yesterday by two automotive photographers here in Oklahoma City. I’ll let you be the judge of the new setup; these really do the car justice. Hope you enjoy! Some More:

Very pumped to share the new dyno numbers with you. Took the car back to Abel Racing last night, and Andrei Mitine tuned the low boost map for the target goal of 25 PSI on E85. The car put down an amazing 726whp/502tq! Enjoy the video, and look for a race gas video in the next few weeks. Shooting for 35 PSI, and 900+ whp. The Video: http://videos.streetfire.net/video/Underground-Motorsports_183088.htm Dyno Graph:

The car was completed today, and I’m very pleased with the finished product. The plan is to dyno tune the car tomorrow, and I’ll upload the graphs as soon as we finish. The car sounds beastly in person, I wish you all could see it in person. Special thanks again to corporate sponsors: BF Goodrich Tires, Tial Motorsports, Borg Warner, Abel Racing, Je Pistons, Eagle Rods, Tomei USA, and many others along the way for your help with the vehicle. As promised, here is the debut video of the new setup: http://videos.streetfire.net/video/Underground-Motorsports_181811.htm

I want to start out by thanking the guys at Abel Racing in Midwest City, OK (Specifically Erwin, who goes by Efeezi on the various online forums.) You guys have been a pleasure to work with, and your knowledge of all things Nissan is amazing. It's been six months since the 240SX encountered bearing damage, which led to a full motor rebuild. This downtime gave me the opportunity to rethink the current engine configuration, etc. While I was happy with the power of the Borg Warner 74mm (1.10 A/R) turbo with 9" cover, the spool characteristics weren't ideal for a street car IMO, and I wanted something that could make similar power, while providing a larger powerband. After consulting Borg Warner, they recommended their 72mm (.90 A/R) ETT Turbo with their new 10" Race Cover, which has been dyno proven to make up to 60whp over their standard 9" cover. The motor was rebuilt with an N1 Crank, JE Pistons, and Eagle Rods. Head was left untouched from the previous setup, complete with Tomei Hardware and 260/260 Poncams. The car now sports the new Tial 50mm Q BOV, which sounds amazing, to go along with the Tial 60mm wastegate, and I'll have some dyno videos to post this weekend, pending all goes as planned. Here's some sneak peaks from what's to come. Forgive the dust, it's been tucked away in the corner of the shop for several months awaiting parts.

And it does....

It sells here for around $2.50/gallon....Factory in another 30% for fuel efficiency, and we are still around $3/gallon... Much cheaper than the $12+/gallon I'm having to pay for C16 in Oklahoma. That's my reason for using E85.

Update: Wanted to welcome Deatsch Werks to the list of corporate sponsors on the project car. We went back to the dyno this past weekend with a set of 1600cc DW Injectors, and they performed flawlessly. The car now has plenty of injector for the current setup. With that being said, the day didn’t end up as we hoped. We maxed out the dual Walbro 255 lph fuel pumps @20 PSI on E85. The car made just over 650whp before we had to call it a day. I made a call to my friends over at MagnaFuel this afternoon, and they suggested their street friendly, Inline Protuner Series Fuel Pumps. The particular model they suggested is MP-4303 rated at 2000HP in N/A Applications using gasoline. (good for around 1300 HP on E85). What’s unique about their race pumps is they are E85 compatible, rebuildable, and they don’t require a fuel controller like the Weldon’s. (And various other brands of “race†pumps.) This is a significant cost savings, and makes this pump is fairly “bolt-on†affair in a car with an aftermarket fuel system already installed. The new fuel pump will be installed in the next two weeks, and I will write a review for those that may be interested in our findings. We knew three weeks ago the 1000cc injectors and dual walbros were not going to get us to our goal, but I wanted to see how far they could be pushed on the E85….as I know many on here are debating switching over in their own vehicles. Here’s the latest dyno video, notice the fuel pressure gauge video at the end: Underground Motorsports Demo Car1998 RB26DET 240SXMaxing out the dual Walbro 255lph Fuel Pumps at 650whp@20 PSI.Borg Warner S374 Turbo, 1600cc Injectors, E85 Pump Fuel, AEM ECU, etc.

800whp on E85, 1000whp on C16

Update: Went back to the dyno this weekend with new fuel pumps, and ran into our next problem, maxing out the 1000cc injectors at 624whp/442tq. 1600cc injectors are being installed this week, and we'll head back to the dyno for round three, haha. The E85 really requires big injectors, and I never imagined we would max out the fuel system this quickly. Im guessing we're going to end up with a Weldon Race pump, as the dual walbro's are really struggling to keep up. Enjoy the Vid! http://video.google.com/videoplay?docid=4416974422287815456&hl=en

Here's the latest update, the car is finished with the Borg Warner 74mm Single Turbo, and the new 4" Downpipe and Exhaust. The turbo back exhaust is straight 4” piping broken into three pieces via V-bands. Photos are posted below. This thing sounds absolutely wicked, and we are putting together a dyno video to post up. I want to thank Matchless Performance in Addison, TX for the piping work, as it came out flawless.

When I sold my Z06, I transferred the plate onto the 240SX, as I decided to start street driving it. (Was being used as a showcar for BFG Tire Co.) I usually pull the plate off for shows, etc but somebody snapped this photo as soon as I arrived. (I found it online and uploaded it into my Photobucket.)

The whole car used to be carbon fiber two-tone, but then I ordered a Cwest Full Body Kit to change the look of the car. (Had been shot for a few magazines, and I wanted to update the look to get back into more magazines for 2007.) Well, the container showed up and the rear bumper was missing. I ended up keeping the carbon rear, and decided to eventually paint it. I just have not done so yet, but may in time, who knows. In regards to the wheels, what's the issue? They are 18x10 with a 295/35/18 tire. On a 240SX with a factory 6.5" (205/55/16) wide wheel, there is going to be some overhang.
