I have a couple of questions on my new turbo setup. On my previous setup (stock sleeved, stock head b18c1 w/ cp psitons and eagle rods, t3to4e @ 16 psi) I ran a HKS SSQ bov on 2.5" charge piping and a 38mm tial on a maxrev log mani.

This setup I'm going for about 200 more hp (550 ish) and will probably be pushing upwards of 25 psi from a gt3561s. My questions are:

Will the tial sport wg control that amount of boost, or should I go with something larger? It will be a custom made ram horn style equal length manifold.

My next question, is will the hks ssq be effective at that pressure and 3" cold side charge piping? I'm sure it will be, but i have been considering doing dual's, for a different sound. If I do dual bov's, i'll probably go with 2 RFL's b/c I've never heard two... anyone heard a setup of those? thanks

 

Tial and HKS make great products...wouldn't worry about either failing

 

Thanks, I'm mainly worried about the wastegate not being able to control at those boost levels, but I think it will be ok. I was only thinking about changing the BOV for preference reasons mainly. I'll most likely reuse my Tial WG and either buy another SSQ to run dual SSQ bov's, or sell my one SSQ and buy two RFL's... I'm debating that still.

 

if its a 35/38 mm wastegate you need to get a bigger one, 550 hp @25 psi is a race car, and you need parts for a race car, not a street car...

 

But it's gonna be a 550 hp street car! haha, I was afraid of that. I'll go ahead and go with something bigger to be on the safe side. Thank you.
