Last week I was able to install a set of twins on a 04.5,6sp I did a before and after dyno with just an EZ. Stock turbo w/ez hp was 315, with twins 340. The truck had no gauges so no before and after heat/ boost. The twins were hx40 and ht3b, and for having a 40 on top, and only a 65hp box the 40 spooled very well.

And another

 

Why are 2nd gen twins posted in the 3rd gen P & A?

 

Probably because they're bolted onto an '04.5 600?

 

I think the misunderstanding came in because the twins on the 04.5 are bolted to a 2nd gen ex manifold which BTW is brilliant!

Nice setup

What are the two brass fittings on the intercooler pipe in the first pic? Blowoff valves?
