I am building a OBD1 B18A and i want to turbo charge it. What compression ratio should I go with when i go to buy some pistons. I want to build a nice street car that has no problem launching.

my first build






bringing it home from the junkyard

20:1 for sho!

haha jk,

9:1
9:7

those are pretty good

8.5:1 - 9.5:1

Anywhere in there is a good CR for boost. I have Wiseco 8.8:1 81.5mm pistons in my setup and I love it.

I hope your are going to take it to the machine shop. Plus those cylinder walls don't look to good. may need to get bored over. If you want a street car try to shoot for 9:1 compression

9:5:1 is a good round number.

You should of gotten the block decked.
