SRB Power ltd Posted February 19, 2004 Share Posted February 19, 2004 Is there a particular make of piston you generally use? Going by the fave tuner poll, I'd guess most of you choose HKS or JUN, would that be right? Does price come in to your choice, in the mian I mean? Thanks in advance for any that reply:) Dan Quote Link to comment Share on other sites More sharing options...
Branners Posted February 19, 2004 Share Posted February 19, 2004 I think theres a few different makes of pistons going in the supras now, JUN are probably the ones to go for but they arent cheap (cosworth pistons rebranded). JB Quote Link to comment Share on other sites More sharing options...
SRB Power ltd Posted February 19, 2004 Author Share Posted February 19, 2004 Hmmm, interesting first response, thanks. How much are people paying for the JUN ones if someone doesn't mind? Thanks Quote Link to comment Share on other sites More sharing options...
Guest Terry S Posted February 19, 2004 Share Posted February 19, 2004 JE's are good. HKS alter the compression ratio, and turn the engine into a interference type with 264 cams as they do not have valve cut outs. I have no knowledge of the JUN's, i.e weight etc. Their stuff is normally good. Quote Link to comment Share on other sites More sharing options...
SRB Power ltd Posted February 19, 2004 Author Share Posted February 19, 2004 I gather you guys don't need pistons until 500+ hp or so, is that about right? What's the ideal comp ratio for that sort of power? and what do they run standard while we're here:) Thanks again and sorry for the Q's Dan Quote Link to comment Share on other sites More sharing options...
Guest Terry S Posted February 19, 2004 Share Posted February 19, 2004 500 seems fine on stock. It all depends on what fuel, how much fuel, and what boost. Stock compression is 8.5:1 What boost do you want to run. This will have a major factor in deciding your comp ratio. Quote Link to comment Share on other sites More sharing options...
SRB Power ltd Posted February 19, 2004 Author Share Posted February 19, 2004 So dropping the comp to around 8:3 to run a bar and half maybe 2 bar and mapping the ecu nicely would probably be ok? Is that a fair route to go? Quote Link to comment Share on other sites More sharing options...
Guest Terry S Posted February 19, 2004 Share Posted February 19, 2004 1.5 sounds a lot more realistic than 2 bar. Quote Link to comment Share on other sites More sharing options...
