S13LSx

I have a cam only L33 like Skinnies in my IRS Nissan 240sx. Whats the record? I know he went 8.6x and the Nova with the 6.0L and the billet 76 went 8.3x but I think the Nova had ported heads???

Just want to know what the record is....

Here is what mine did this weekend with a LS1 intake, used 216/221 cam, and a 75/83mm BWS475. It also had an EBAY 4" a2a and iat's went from 81° at the line to 151° at the traps. I also ran out of gear and bounced off the limiter for the last 75-100'.......

Nice run and congrats. You may need to drop down to the 350z 3.33 LSD if you plan on staying with the Nissan IRS and want avoid running out of gear.

2nd option is the r200 diff from a 2004 to 2007 pathfinder which came with a 3.13 gear.

Can't imagine a pathfinder having a 3.22 gear. I know all D21 and R50 pathfinders... 1986-2001 models were offered with either 4.36 or 4.60 gears. What pathfinder have you seen with a 3.22 gear? That gear in a truck with a V6 doesn't sound like Nissan engineering to me and I'm a Nissan nut.

Although, I know the 2003-2005 Q45 has a 3.13 gear. It is open diff and the axles don't fit my car so I will have to swap the 3.13's into my 3.69 diff.

The 04-07 Pathfinder R200 diffs are 3.13....accidentally put the wrong info before...fixed now. I can pm you the link to the info for the swap if you needed it on a Nissan forum.

The 350z has a 3.33 geared diff.

Here is an article with the diff swap info:

I found an 03-05 Q45 diff with 3.13's and I'm going to swap those gears into mine. Then I can use the same axles with my J30 3.91 diff and switch from 3.13-3.91 in 30 minutes on a lift. Thanks for the insight though.

Yeah def much easier....the 2 routes I suggested require some fab work for the swap. I will keep an eye out for progress....good luck bud should be interesting to see your times once you complete the swap.
