these pistons seem to be one of the cheapest i have found. the site says they are made of a high silicon and low expansion aluminum. this leads me to believe they are less dense and then less strong than some of the other brands out there. id like to make 300+ hp. whats my best option for pistons? thanks

 

what engine? if its d series vitaras are the cheapeast way to get the 300-400hp mark. plus srp are very good, at least from what i hear by all the people i know running them. personally ive never run anything other then stock so i have no input.

 

It sounds like they are hypereutectic pistons. I have never seen them for an import motor before but they are good for around 250 horsepower I am guessing.

 

they are for a b series. i sure hope that they are good for more than 250 hp as thats what stock is good for about

 

srp's are forged and can handle much more than 250. If vitaras are cast and can handle 400, think how much these will handle.

 

they seem like the best bang for the buck. they are the cheapest and they come with rings!

 

i just bought some 81mm b series pistons for my car srp brand and i researched them a little they are forged and im pretty sure could hand a lot of hp

 

vitaras are hardxly the way to go imo


srp's arent much more and being forged will take **** poor tuning and take it


try that with a cast piston regardless vitars are cast. detonation will destroy cast pistons within a chance to repair the problem


forged will take it over and over again

 

2 main types of forged pistons, low sil and high sil. Low sil are "stronger" but have a tendency to expand more when heated, i.e. piston slap when the engine is cold because of the tolerances necessary for expansion. High sil arent "as" strong, but are still far superior to cast, and dont expand as much under heat. Most street cars dont need low sil forged pistons. srp's are plenty for your 300hp goal.

What he said ^^^^

 

SRP's will break much higher than a horsepower goal you're shooting for... ever. It's all in the tune.
