im building a CA aswell, but lets keep thread about a-series

14-15psi all day on Aseries is alot.. You would have to put some decent gear in one to keep it reliable and handle a good boot here and there. Stock CA's are good for 14-15psi everday and have a few more goodies than Aseries. I think a decent set of Chromie's and rings would be a good investment.

About time you started getting back on here rallycar ...Keep up the Aseries power

well after killing 1 x a12, 1 x a14 and 2 x a15

its time i built a motor to handle this buisness (it's kinda funny, normally people do up there motor and blow every other bit of drivetrain, i've done the opposite)

the a12 had a blown head gasket when i got it

the a14 blew the rings

and both the a15's stuffed the rings, i'd like to re-build one of the a15s (one has stock cam and lightened crank, the other just a mild NA street cam)

plan:

1 bar (14-15psi) boost all day every day

questions:

- i'd love to get an a-14 pulsar low comp head if anyone has one? (this will be my way to lower compression)

- what should i do with the head gasket? what material etc etc? i dont want to o-ring though.

- and most importantly as they seem to be the weakest point... rings... what do you do to make them robust for boost?

- and lastly what would be any other weaknesses to engineer out? im sure it can be done with stock pistons and stuff, i dont think i need to get that serious???
