well i have a 87 rx turbo with an n\a block with turbo heads it has a bad hg win i got the heads off i found a crack in the ridge of the cinder[ATTACH]7363[/ATTACH]

i don't know if this is going to be a problem or not

cracked sleeve? what kind of boost were you running?

 

I have ran a turbo rx on na/block (carb 9.0:1) in stock trim, stock boost and timing, regular gas with no problem.

 

i would just say, ea82t with normal boost, or no ea82t at all. This is the part where everyone has already barked up your tree about the matter.

 

Do as you will, i am not against it. Just do it where it will work vs not work at all.

 

my advice to you is ditch this block and go find a carb block to build on

He's right you know. People don't just say they're a shit engine for the fun of it. They're pretty much the worst engine Subaru ever built...

 

You want power in your EA, repower it with an EJ. Hell, if you NEED boost, repower it with an STI engine and 6-speed.

got the car like this but thank you MilesFox. can i use the na pistons in the turbo block?
