I'm deciding between buying either a gsr block for $150 (which needs an align hone for about $200) or a d16z6 with m/t for $300. If I get the gsr, I'llbuild the engineand gon/a. If I buy the d16, I'lldo turbo. What do you think is the better choice? I'm looking for 225 to 250 hp and am hoping to spend no more than $5000; but that is only a hope, not a limit!
