Are there more powerful twin turbos other than bnrs or 99spec

 

99 spec is hardly any morepower than stock.

Knightsports makes some upgraded twins, if you can find them.

BNR 3s are the most powerful option out of sequential twins. You can get 400hp out of them.

Don't forget Pettit.

My stock turbos were...tired when I bought my FD, so it's tough for me to tell just how much of an upgrade they are from perfect stock turbos, but the Pettit turbos in my car made an unreal difference.
heh, The 1st time I drove my car after they were installed, I began to think about upgrading my clutch.

 

ive gotten 365 WHP (with room to grow, ran out of injectors ) On my street port FD. Everything else is completely stock.

 

 

I got a 93 fd its stock. But the only thing i got is a Re amemiya filter or the intake, well its purple and huge. Will I need to modify anything in order to install the Bnr's of 99's or rf420's
