Turbo VN

Hi guys just wondering what boost is acceptable on stock injectors and fuel pump for a 3.8L Buick without the possibility of leaning out.

Only looking at 8-10psi, if that's not achievable I'll get new injectors and a pump, just wondering if it's really neccessary. Thanks in advance

Turbo is a small Hitachi ht18s-2s Twin Scroll of a 13b rotary, so by the time it spools up around 3,800/4,200 it won't be able to throw out much more than 12-14psi if I'm lucky.

Also, car won't see the road again, only work around the farm

they work good as twins single probably too small https://www.youtube.com/watch?v=3b1THbWxRIA stock injectors and pump and tune will only support n/a really

Thanks, I presume they are two hitachis? I didn't think one bank would be enough to get boost consideringrotaries expel a lot more exhaust gasses

Awesome I will check them out when I get home from work
If a single can't handle 10 pounds I'll source another.
Are you interested in selling me a tune when I'm finished?
