anyway, I think I may be loosing my mind. Now I am seriously considering pulling the engine and rebuilding the bottom end with forged pistons and new rods. I just noticed my front main seal is leaking a little, and I'm burning oil I figure out the rear turbo seal.

I don't know, the current bottom end gives me perfect comp. and 2% or 3% leak down on each cyl. (all the same). Would it be worth it to build it up? should I just say f it all and go to an rb25? I am questioning everything now.

I need some encouragement so I just don't give up.

choices:

-fix front main seal, then go to a bottom mount gt3071R, power FC, and big injectors ---like $3-$3,500

-Build bottom end, go to a T3 topmount, power FC, and big injectors--Like $5000

-sell SR, go to RB25 mildly stock --like $4,000

Would a built SR be way more fun than mild RB? Horsepower is horsepower i guess.

something to think about is that SRs part are a lot easier to come by than RB parts because we had them installed in a variety of cars here in the states. Can't exactly go down to the autozone and get a seal or something for an RB. Even if you don't decide to go with my setup I would suggest staying with an SR.
