I have a 93 rx7 R1 that I did the poor man non sequential turbo conversion since the rear turbo wasn't boosting and couldn't figure out why. After the conversion I get a max boost of about 7psi. I want to raise the boost level up to about 10psi. Is it possible to do so by adding a manual boost controller? I know the dangers of raising boost on a stock level car but I have no intentions of boosting past 10psi. So any help would be great. Thanks!!!

 

yeah a manual or electronic boost controller should do the trick

 

I've never installed a boost controller on a stock twin before, only on single turbos with external wastegates. How do I hook one up to the stock unit?

 

you tap the stock "wastegate" vacuum line and add the boost control soleniod.

step 1- get a boost controller.

after you do we'll go from there
