I was wondering what else i would need to make 550-600hp?

 

A 4k gov spring kit would help

 

Bigger charger, to be safe stud it too.

 

What about twins? Doesn't bd make that kit to upgrade a single to twins for like $2850?

 

Your 95 looks to be an auto trans, so you're working with a 160 pump right?
That pump is gong to have a tought time trying to hit 550-600 on fuel only.
You'll need twins for sure, just hang an HT3B and piping kit under that HX40.
You'll most definitely have to O ring and stud the head. And probably a cam.
This might get you into the low 500's, but I really think you'll need a bigger pump to see 550.
And what kind of tranny do you have? Please don't tell me it's stock right now...

 

The trans was rebuilt but it only has a mild shift kit and a HD tc what ever that is to them but it slips with the trans locker on...... i kinda figured i would need to get a bigger pump. And how is a 5kGsk i seen them for sale does it really pull at that rpm? do you know anyone selling the pipeing for twins?
