Rebuild for Turbo
I have decided to rebuild a 12a and basically wanted to know if there is anything I should do special to the internals to make sure everything holds up to boost pressure. I plan to run my boost up to approx. 12psi. I would like to occasionaly push it higher but I have heard that 12 is a safer number. If not let me know that to. I also will probably have an extended street port. Thanks for the help

i am planning on turbo. i would like to know what should be done also. have you tried searching?
|
searched
I have done a lot of searching and reading and have found a vast wealth of knowledge, just not a whole lot from an internal perspective. I just hate to build a motor and blow an apex seal out the exhaust. I guess I should also have mentioned that I am going to be running a weber blow through setup.

Lower compression rotors?
|
hell, i wouldnt even lower the compression. :p: you need to "stud" it or "dowel pin" it. keeps things together under pressure. get better quality apex seals. what kind i dunno. other than that, enjoy your boost. :D
|
i would at least try to lower the compression ratio to 9:1. better apex seals are a must and all new dowel pins are a must. they can stretch over time and cause bad things to happen.,

Apex seals
When speaking of apex seals do you mean going to 3mm or a different material?

Unless you can afford ceramic seals, use new stock apex seals. The dowel pins are squeazed into place inside the motor to stiffen the rotor housing's rigidity. They are not at risk for stretching and for 12psi I would not worry about adding additional pins to the motor. New tension rods may be in order - but in my opinion, unnecessary as well.
