Based on the calculations in the tables, the air flow is around 80-85 lb/min to sustain 500hp which to keep your air/fuel ratio in a good zone. All it boils down to a compressor wheel in the zone of 64-66mm..

Here is the post if you want to read it..Good info for anyone looking at turbos..

Picking the right Turbo

 

I personally would go with a 62 14,, I think that you will outgrow the 13 in no time. A 6280 might even be better than the silver 62 for your application IMO

I forgot that NADP sells High Tech Turbo. I'm going to see what the price difference is from me bringing one in from the south vs. NADP's price.

 

I would be interested in the difference too.. Personally I would call PDW or II directly..

 

Really....

 

Dude, buy a 64mm HTT now from PDW!!! Less than $1300 for a quick diesel 64!

Holy you know what! I wonder why the 64 is $300.00 cheaper than the 62? What a steal...

 

Don't even wonder. Just order one. Better yet, make it two. Man, I wish I had my card cleared off for that. I'd pick one up on Monday if I could. It could very well be a typo, but I bet Doug would still honour the price. If thats the case, I bet choosing between the 62 and 64 just got easier.

 

No doubt, I can always downgrade to the 62.

 

How much extra is the stainless housing?

 

$200-300 if I remember correctly.

 

Stainless.... Bah... (oh, I told you to call PDW!!!!)

 

You did and that's where the deal is...

 

Hey, just tryin to help a friend out.. Thats were I had found a good deal on a turbo, until I made a deal on a used one from a buddy down south. Its not as trick as the HTT or II PS versions, but it works. Also I wasn't planning on needing a 64 size as my fuel mods won't be so drastic.

 

You'll need a 64 once you put those DDP4's in, no?
