twin setup advice

[Coaltrain03]

I'm not sure if this is the right part of the forum to put the thread in, if not please delete. I'm looking at pitting twins on my truck it's a 95 12valve 5spd has 180 pump, 5x16 injectors, 5gsks, 191 dv, headstuds with factory turbo for now. I drive it daily tow with it occasionally and of course give her hell lol once in a blue moon. I'm just wanting to know what to be the setup for me to run any advice would be great

he351 with wastegate drilled out over a ( 3b/s475) 75mm would be a cheap and work well

^^^^thats what I run..he351 over ht60..cheap and it pegs my 60# boost gauge rather quickly..

 

[Coaltrain03]

What about wastegates I've always just ran a single so I'm new to twins, is it better to have one or not

 

[winkdemon]

yes need a waste gate in the secondary to limit drive pressure , just need to drill the he 351 out to help it flow ,

 

[Coaltrain03]

So a wastegate on the manifold is the secondary your talking about correct

 

[whitneyj]

He's talking about the wastegate that's internal to the secondary (HE351)

You can drill/open up the waste gate to 1" (or larger if you can weld and have old engine parts at your disposal).

300 over 400 wouldn't be bad either, I got a complete s357 over a s471 im selling complete bolt on setup if interested

My favorite set of street twins was a 62/65/12 over a 75/96/1.10. Spooled plenty quick with minimal smoke, and ran mid 11s.
