info on b-series engines?
im doing research on a ls/vtec high-boost turbo setup.
i tried the search feature, but i still have alot of questions
i was wondering if someone knows of a site or somewhere i can find all
the differences between b16/ls/gsr/b18c5 head and block. and the
benefits of mixing and matching certain heads with certain blocks.
one of my key questions: whats the difference between bored out b16 to 1.8 with low comp pistons vs ls/vtec setup? (for turbo)
can someone point me in the right direction?
thx,
steve

i was searching the same thing the other day and i typed in "b16 b18 block" and searched the recent and archived and got a ton of results.. some were useless but there were other good ones

Well I think a the LS block is better for boost, IMO between the B16, but for me personally, since I built my GSR motor its ready for boost and thats the better engine to go with, um PM and I can get you some links later on

I'm not sure of any one site that will give you all the information you're looking for at once. However I might be able to point you in the right direction.
The LS block is inexpensive, with a lower rod ratio than the B16 or GS-R block meaning more torque. The LS is 1.8L, the B16 is 1.6L, and the GS-R is also 1.8L but with SLIGHTLY less displacement than the LS.
The LS lacks a few things that a B16 or GSR block has such as more bracing in the cast of the block itself (no big deal), oil squirters aimed at the underside of the pistons to cool them down... and slight differences in the rotating assembly such as weaker rod bolts than the GS-R comes standard with.
All in all, the LS motor was not "made" to rev as high as a B16 or GS-R motor, but it does have a bit more low end torque right out of the box. With some minor changes such as forged pistons and rods, the LS shortblock can be a great boosted block OVER the B16 because of it's torque/displacement capability.
This is all thrown out the window if you're planning on "sleeving" the motor. When you replace the factory sleeves with units from Golden Eagle, RS MACHINES, Benson, etc... you change the situation altogether. You can now use 84mm (or larger) pistons in these blocks, which will change your displacements on each block by about .2L. Therefore if you have a B16 block sleeved, with 84mm pistons, you're right around the displacement of the LS or GSR block is when it's in stock form. But this also means if you want an even larger motor, say a 2.0L, you can achieve that by sleeving the LS or GS-R motor.
Alot of people will argue different points about these three blocks. But I will give you my own opinion. If you're on a budget, work with an LS block. You're going to have more displacement, and all you really need to add to make very strong numbers are pistons and rods.
IF you have a slightly higher budget, go with the GSR block. The crank is reinforced in its main caps by a crank girdle, the rod ratio is sufficient to rev very high, and you're starting off from the get go with 1.8L of displacement vs. B16's 1.6.
I know I left a lot out, but that should get you started.
