Its just a head/cam ls3 with a 250 shot of nitrous. It has a 4l80 trans which is just a turbo 400 with overdrive. 27x11.5x15 hoosier quick time pro tires. The pass it broke on was actually without the bottle and it goes low 1.40 60's off the bottle.

Time for an R230...

I can't remember who maybe Mazworx but someone was developing a kit to drop in the 03/04 Cobra IRS components.

Close...

This is for S14 subframes only and uses the Ford Explorer IRS 8.8 rear end. This setup can handle over 1,000HP with absolutely no issues.

http://www.mazworx.com/mazworx-240sx-8-8-irs-kit.aspx

If you send in your subframe and get the custom DSS axles you're only looking at $3,345.00

Includes:

Laser cut unwelded brackets
Rear Cover
Solid Aluminum Diff Bushings
Hardware

Customer must use:

07-10 Ford Explorer 8.8 Diff (comes 28 spline)
Q45 or Z32 TT rear hubs (32 spline)

You can get a spool dirt cheap as well as a 1350 chromoly slip yolk and an upgraded pinion with a better spline count.

The best part, everything can be over nighted from Summit or Jegs, if you're in a real bind many local speed shops will have 8.8 parts.

The bad part is that I don't work there anymore to sell it to you guys lol. In all reality though if someone does seriously want the kit I could sell it through Real Street for the same price.

The 8.8 would be the ultimate but I'm really trying to avoid the aftermarket axles and the cost associated with it if possible. Thats a lot of coin to still be irs at the end of the day

hanzbrady

I see where your coming from, the setup is for guys who want the ultimate compromise in street car handling and drag car performance.

Another nice thing is that this allows you to remain class legal for classes such as Street Fighter that don't allow for modification of the chassis to fit a proper 9" with a 4 link.

Just a note this setup has cut a 1.16 60'

Agreed, if you're strictly drag, it doesn't make sense. However, I'm sure any fab shop can duplicate this setup relatively easily.

Using the handbrake to load the transmission,can anyone say what rpm you launch at ,do you hold the rpm steady or fan the rpm ,average about 500hp with et drag slicks 26x10

TheRealSy90

I'd assume you want to hold it steady, as if you had a stall on the torque converter.

There are too many variables to offer you a set rpm. I'd raise and hold steady, slip the clutch as you can. You really should look into some type of launch control. I'm assuming you're boosted? If so, it'll be a dog off the line if you have a decent size turbo.

I used R32GTR axles with my R230 swap, i did a small write up on the swap on this site.

Hey guys,

Since I didn't see anyone mention this, at Import vs. Domestic this past weekend Mazworx broke the world record for fastest and quickest SR20 running a 6.685 @ 217.35 MPH.

And Duy, with the "White Rice" 2JZ-GTE S14 went 6.99 @200 MPH. then went 204MPH in a later pass, apparently, it still has more left in it.

Chris Delgado at Prospeed is who tuned my 2j s14. Amazing tuner, not surprised that car ran that fast

Curious to hear how far anyone using the DSS "600hp" axels have managed to push them with out breaking?

Starting to break stock axels every couple passes now.

I'm pretty curious about this too since at that power level the realistic weak points become the ring and pinion as well as the stub shafts.

The only value I see int hose 600HP axles is for street cars or drift cars that don't plan on dead hooking 600HP with a sticky tire.

why even use the DSS axles? small spline still..

hanzbrady

Like I said they make sense on higher HP cars that slip the tire vs hooking it like in a drag car.

Drift cars tend to rip CV joints apart and snap the actual axle so the DSS kit makes sense for that.

I just don't think it's fair to call them "600HP Axles" I'd say they should be called something more along the lines of drift or road race axles.

A 600HP kit for drag racing would at least need to come with better stub shafts imo.

The DSS axels are the easiest way to upgrade a part that’s currently breaking every couple passes.
Just trying to see if there are people actually getting away with using the 600hp ones as there’s a big cost difference between the 600 and 900hp ones.

This is a 600hp SR20 S14 that has a race weight of 2750 and uses a 26x10 ET Street bias ply tire.

The setup that seems to be the best compromise between price and benefit is the R230 differential with modified stub shafts and 350z axles or a R230 with the Q45 and 300ZX TT axle.

I've personally seen the latter make it until the 1200HP mark.

If it were me and we were ignoring the cost I'd do the IRS 8.8 in a heart beat because it solves every issue at once.

Also from what I'm told the difference between the 600 and 900hp Axel is the outer cv. The 600 has the Porsche cv on the inside only where the 900 has the Porsche cv on the inner and outer. The rest is the same.
It's the inner cup on stock axels that breaks every time on the driver side axels right now.

Finding the q45 with proper axels is the hard part. Has to be the later one as a 3.54 gear won't work. Looking for a more simple solution. Fabbing in a 8.8 isn't happening right now.

I would like to know this too , How much the 600hp dss axle on stock s13 r200 diff setup can hold ? 500whp s13 street driven and occasionally 1/4 mile ..

juiced305diesel

I have a s14 sr20det powered by a pte6262. It currently makes 680ish to the wheels. I have a tomei 2way and dss 600hp axles and i have yet bust them. The car is currently on a 285 nt555r drag radial.

What kind of 60 foot do you pull? What’s your cars race weight?

I do not drag race. Car weighs 3080 with me in it full interior fully loaded model.

What will be the most ideal diff ratio for 550hp and a 26x10 et drag slicks
