Help me choose a cam 5.3 with a s480
 

My old setup was a forged lq4 with a borg warner s480 turbo with the 1.32 96mm wheel exhaust and race cover compressor housing. It made 770whp with a Zo6 cam threw a powerglide and ptc 5500 stall. I ran 9.52@147. Long story short - I lost a lifter and damaged the cam. I also lost a rod bearing. Now I'm running a stock lm7 5.3 and want to pick a cam that will do good in this setup and eventual swap it over to the 6.0 when I get it back together. Also for the 6.0 I think I'll switch over to a ls3 head & intake when I get it back together vs the 317's I was running. The last thing I would like to mention is I'm running comp 918 springs so I was trying to keep the lift well under the .600 rating. I'm shooting for the 850~900whp range and hopefully 8.99's.

So the two I was thinking about were the:
Comp xr281hr 228/230 .571/.573 112 $349 - hotrodmag 4.8L twin 76mm = 1200 flywheel hp

or

speed inc tu1 225/225 .581/.581 113 $380 - http://www.ls1speed.com/article2/index.htm - 76mm 348ci = 851 wheel hp

Here are some picture of my setup.

How will it spool with a 1.32 ar on the 5.3 doing same build im going with the tu1 cam....

Still debating on my cam for almost the exact set up...different intake but same turbo with l33 5.3 and 317 heads. The only "turbo" cams I saw from comp had .60x lift which is more than I want as I think the heads will be done at .550ish.

I'll have to get back to you on that. Haven't really gotten to beat on it yet.
Here is a link to the 6.0 Dyno Graph from last year.

curious what cam you ended up going with

Wondering if some of the more "NA" split cams might not work better on the large turbo with a smaller motor. I was looking at an article last night by gm high tech where they took a 5.3 and tested it with 2 cams by comp and stock vs fast 102. Interesting findings. They can cams and intake both in NA trim as well as with the turbo.

I ordered the COMP CAMS PART NUMBER #54-428-11 - XR281HR

I'll let you guys know how it goes when I get it in.

How much does your datsun weigh without you? I love that little mother fucker.

any updates

I ended up grabbing the Lunati 277/283 cam after a good bit of discussion with LilJohn over on YB.
