So, after swapping to beefed up axles, are you worried about lunching the R200?
I always just assumed that the Mazworx car was running some R230 derivative since it's swapped to a Z32 tranny.

I wanted to post some pics of the build on my car to show it's progress level.

I had to order custom motor mounts for the car, and they should be here sometime later this week.

Right now, it appears like the car is 2-3 weeks from being completed.

It would be much sooner, but I am still waiting on parts to arrive from Japan.

Yes.

I'm down in Burleson, TX. My brother (who lives in Searcy, AR and has the KA-T 240SX) now runs Underground Motorsports, an online webstore.

CylonFrakker · 04-20-2007, 12:05 AM

Riggs you left Nashville???? Fuck me dude I have not seen you since that Tungsten (Fucking Vending Machine fat bastard) crap on Tennesspeed. If you still got my number bro gimme a shout. Omari and I been wondering where the hell you been. Got some stuff we wanna show you. Going all JP on a 98 GS300 you have to see this thing plus its got the balls to back it up on the dyno. Cya man take care.

What's the hole for?

arkive43 · 04-24-2007, 12:35 PM

On the recommendation of an Australian GTR tuner, I had the machine shop remove the top freeze plug in the back of head.

It was tapped with a 1 in. NPT thread, and I will be running a -12 AN return line back to a welded in fitting on the the oil pan.

The RB26 has many issues with too much oil being trapped in the head and then starving the oil pan at high acceleration.

This should just about eliminate this issue at 8000+ RPM, as under acceleration most of the oil will rush to the back of the head and return back to the oil pan.

We used a Tomei Oil Restrictor in the block, to even further try to decrease any issues.

If you are running a RB25DET block, then most of the tuners weld one of the two feeds shut. The RB26DETT block already has one of the oil feeds welded closed from the factory.

I'm not really considering that setup right now.

I built this car to rock and roll on the 1/4 drag strip, and the occassional pesky Supra/Viper/Vette on the wangan.

yokotas13 · 04-24-2007, 03:10 PM

but, your nowhere near teh wangan lol

Ian · 04-24-2007, 04:46 PM

I was about to say...Does that bridge stretch all the way to AR now?

Jeez...they musta done some construction since the last time I was in Japan

kouki_s14 · 04-24-2007, 06:11 PM

How far back is your motor sitting? Seems like that might give you some firewall clearance problems.

ZenkiJunkie · 04-24-2007, 07:03 PM

so...whos gonna drift that thing?!

That was just to demonstrate what the hole was for....

This is the actual piece I am using, simply waiting on it to come in from Australia, Mate!

Have you figured out what you want to do for traction yet?

Walperstyle · 04-25-2007, 09:02 AM

too much horsepower

Yep, BF Goodrich Drag Radials for the street, and MT ET Street Slicks for the drag strip.

The car has a full suspension setup, and I dont think there is any piece that is stock, all the way down to bushings.

godzillarb · 04-25-2007, 09:31 AM

Are you going to do any tubbing or over fenders?

mayco_86 · 04-25-2007, 01:46 PM

lOOKING REALLY NICE.

fORGOT TO ASK YOU HOW BIG IS THAT TURBO.

Never Mind I Forgot It Was A Gt4088r

Over Fenders highly likely, tubbing no..

umsports · 04-26-2007, 12:32 PM

Well, the decision was made to go with a Ford C4 Tranny w/transbrake and GearVendors Overdrive Setup. This should allow the car to remain very streetable, yet a solid performer on the drag strip.

ATI transmissions is currently sponsoring the car with their Super Damper, so I am giving them first shot at the tranny.

If not, I have decided to go with Performance Automatics http://www.performanceautomatic.com/transc4.htm and the PA26107 Super Comp Tranny w/Transbrake, as this is supposed to be the top of the line performance C4 tranny on the market.

PA offers a lifetime warranty, and will replace the tranny if it fails. That speaks volumes about their quality.

After talking with Ivan @ AMS, and [email protected] Desynz Motorsport in Australia, it's a no brainer.

In Australia, they make a Cast Conversion Bellhousing to mate the RB block to the C4 tranny. This will be great, as the swap will be clean, and it should look like it belongs in the tunnel.

I'm still curious on how this car will hold up with the 4.08 OEM rearend.

No worries, as BF Goodrich is the main sponsor on the car, and getting tires has not be an issue thus far.

corey240 · 04-26-2007, 07:05 PM

they are gona impound your car and youl never see it again, the last thing you want to do is screw with some douche in a vete and get your car towed. nice progress, you beter have videos of this hit when its done.

umsports · 05-04-2007, 10:58 AM

Hey Guys,

This footage is from 2004, and was used in the 2007 release of the movie Adrenaline: Unleashed from www.srvidz.com

It's a 30 second teaser, but you get the idea.

This was the Underground 240SX completely stock with the boost controller on the stock turbo's set to 16 PSI.

The SRT-4 was running 18 PSI plus a 75-100 shot of nitrous.

Who needs tubbing when your going straight?

Nice job so far Chris!

umsports · 05-09-2007, 06:28 AM

Yesterday, Andy at Southern Imports in Murfreesboro, TN (Mechanic on Project 240SX) installed the Mazworx Axles w/Hubs (http://www.mazworx.com) and SPL Pro Aluminum Subframe Fushings. (www.splparts.com)

A little brake cleaner and some black spray paint really improved the look of the spindles.

As you probably notice, the threads on the hubs are extended for use with aftermarket drag wheels.
