b20vtec hp question?

By 93hatcheg
- Sun Mar 28, 2010 4:04 am #184152 my buddy just bought a b20vtec from some guy in sac. he says its been professionally rebuilt and has b20b block, gsr head, ycp pistons, block guard, type R intake mani, venom nitrous piston rings, titanium vleves and aftermarkete springs and retainers, idk about what con.rods and bearings and crap it has but....

they say its gonna have 350hp? i find that to be bull shit... what do you think?

He might get 200whp out of a really good tune, but that's getting into the outer relm of possibilities.

Like everyone else has stated, this motor sounds like BS. ITR manifold wont fit a gsr head. the lack of real specific info shouts out that its not a good motor.


There is no way that that motor will make 350hp. anywhere, crank or wheel unless some sort of help is used.

also they said it had like 14:1 cr with a b16a head and they installed it in his car and the second it fired the pistons smacked the head! now i told them to try a gsr head ( cause the combustion chamber is bigger) and it runs but there is a small chip outta one or so the pistons lol!!!

x2, my buds b20v build on stock parts, bone stock bottom end, b16head, gsr cams and stock intake, just a header and short ram, made like 170whp...

and the gsr head has a smaller combustion chamber so thatd make the compression even higher....

B16a chambers are bigger than GSR chambers. How it got 14:1 CR with random pistons is a little odd.
