hi you guys, can you please tell me what would be the best to use in my s14.
standard hydraulick lifters or the solid ones and where would be the best place to get them.
tks

Converting to solid lifters will be costly but if you have the money then go for.
Solid Vs. Hydraulic Lifters
Thanks to recent innovations in reducing valvetrain mass, hydraulic roller cams are revving higher than ever. However, for sheer performance, solid lifters still reign supreme for one simple reason. "Stiffer valvetrain components provide better control as engine speed increases, and this increases the rpm limit of the valvetrain, since deflection is decreased," says Billy. Deflection robs the engine of the valve-open duration it needs as engine speed increases. Bigger cams are conducive to high-rpm performance, but as rpm increases, the loads on the lifters, pushrods, and rockers increase as well. Due to deflection, this means the engine sees a smaller cam at high rpm. "Up to about 6,000 rpm, the inherent deflection of hydraulic lifters isn't an issue, and many are used satisfactorily to about 7,000-7,500 rpm," Billy says. "However, even if valvetrain control is maintained to 7,000 rpm, horsepower improvements are still common when switching to a solid lifter."

Diesel power, hmm, yes, I think I'll have some of that.

Sr20 can rev easily up to 8K rpm on the standard cams.If you want bigger cams there is types that can be used with the standard springs-look for GReddy easy Cams.To setup solid lifters will cost you a few bucks since you need to change springs also and cams and retainers and then pay a mechanic to gap them which will take at leat 10 hours labour.
