Hello all, I was wondering if I could get some opinions on my bottom end build. I currently have the top end done. The rings are shot on the bottom end and it is puking oil through the exhaust on the second cylinder so I will be rebuilding it anyway, figure I should upgrade the pistons/rods and maybe other things? I will probably put a turbo in eventually too so I would like it to support that at low boost ~8psi. Any help is greatly appreciated. Thanks!

If you mean a low horsepower turbo build later on then you don't even need to build the bottom end. PSI doesn't mean anything especially if you haven't even picked the turbo. Stock blocks are good for 300 horsepower.

I can only assume you're rebuilding with stock components since you didn't mention a piston/rod combo for a boosted engine.

Also if you plan on boosting later on down the line you might want to skip that header and intake. You might want to also invest in a good 3" exhaust.

Biggest thing you can do toward a turbo build is more research.

 

I guess what I am getting at is what set of pistons and rods would be stronger for a future turbo build, and something that is not crazy low compression... Would it just be best to stick with the GSR components or should I upgrade them to and equivalent aftermarket piston rod combo to have it a bit stronger, after all when it has a turbo it will be the daily driver. What other things should I consider having done at the machine shop to the block? Maybe common things...

 

Pick a boosted horsepower goal and then people can advise you better. If the turbo is just a pipe dream for now then don't even take it into consideration in your rebuild as most people never get around to actually boosting.

 

I was hoping for around 250whp.

 

Bump, going to be taking the block into the machine shop in a week or so not even sure what I should ask to have done to it and if I should buy upgraded pistons/rods for the bottom. HELP!

 

You can make mid 300whp all day on a stock gsr motor. So if you're only hoping for 250 then don't bother upgrading the bottom end.

Well they can't do any type of boring/honing unless you already have the pistons and rings so it can be matched up. To me from reading over your post's I personally believe you need to do a whole lot more research first.
