I have a 91 convertible. I wanted to turbo it but I have a couple questions. How much psi and my stock apex seals handle?
I was planning to use turbo 2 parts for the exhaust and intake manifold, oil pan, throttle dynamic chamber. But I was gonna use a new turbo, and a front mount intercooler and attach it were the top mount would mount on a turbo 2. Is there any things else I will need? Should I buy a turbo 2 ecu or just tune my old one? Lot of questions any help would be appreciated!

 

Since this subject comes up every day I would suggest that you search under the words: "6 port turbo conversion".
Doing a Normally aspirated to Turbo conversion just not merely slapping parts on and making it a turbo engine.
Your engine is a 6 port where as the Turbo engine is a 4 port so that needs to be addressed.
Since all of this has been documented,your desire to do this will be based on how much coffee you intend to drink while reading the vast amounts of info this subject has consumed.
