Opinion for block to build
 

I decided to ditch my idea for the non-tec and finally ordered up a complete b16a for the time being. Now i'm looking around my garage and seeing 2 blocks laying there just begging to be built for some serious boost...my b16a block and my b18a1 block. Thing is, i'm not sure which one would be a better motor to build for complete boost ownage. I like the nice rod to stroke ratio of the b16 and i can hook up on TunerToys deal on rods for it, but i know the b18 bottom would make a little more torque. Which casting is considered stronger, even though I'll probably get the block completely sleeved anyway? Lets hear some opinions...keep in mind that this is going to be a full all out build, nothing stock except the crank and i'm more than likely gonna hook up on a huge Garret T-60 or just stick to my t3/to4e 60 trim. So post em up, let's hear some pro's and con's too. O0

i've also thought about this, since i've got a bare LS block and a built GSR head waiting to get raped. also been trying to figure out, will the ACL bearings tuner toys carries be able to sustain 10k rpm's? with the head I have, i want to be able to use it to it's full potential but on a turbo setup

Did you ever get the parts together for that again, gaywad?

The advantage of the B18a is the block is longer, that aside, the b16 has provisions for oil squirters which can not be added to the b18a; not a huge deal but nice none the less. Also, there are some people who've been able to fit LS crankshafts inside a b16 before; just takes a custom piston with the wristpin moved up. Usually these motors are really high comp and are all N/A, not sure if that is due to the builder, or if a high comp piston is the only way to use that crankshaft. Either way, I'd look into it. Also, if the LS crank will work at a high compression ratio, then there is no reason the GSR crank wouldn't work.

the awnser i found when asking that question...

street tires = B16A

all out = B18

that was a nice write up. enjoyed reading all that. where is that guy from?

Re: Opinion for block to build
 

You can add oil squirters to an LS block. It is not a huge deal, and it's not worth the hassle.

Eh, Jeff is a bit of a loudmouth idjit. I disagree with him on a good half of what he says... and saying his IB spec rods are better than Eagle, when they are the same forging, is assinine.

Learned something new today then; I've never seen someone bother with doing that, because like you said, its not really worth the hassle.
