Ok, I´ve been searching around for almost half an hour now and still can´t find what I´m looking for.

Now, when there seems to be a few TC popping on to the market I would like to bring up the question once again about the engine exhaust ports and if they can stand the extra heat and pressure? I know I´ve read about it but can´t find it. So what´s the deal? Can they stand the extra pressure from 5-6 psi or do they have to be reinforced?

 

Come on guys!!! There has to be some of you who knows a thing or to about this... Right?
The actual problem is as far as I understand that there´s a special surface on the exhaustports so they can handle the big tempaturediffrence between the exhausts and cooling water.
ANY input would be gladly appreciated.

 

i cant think of a reason why the exhaust ports wouldnt or couldnt handle FI. but for a defintive answer follow mazdamaniacs thread about his turbo. if there is going to be some kind of issue he will know first.

 

Ports shouldn't be the issue, the seals however.. have been questioned by many for some time, and I don't have the definitive answer.

 

There are no issues.

 

..and I should have added that the majority of wrench-inclined people that have chimed in have said just that, thank you RG
