I have a b18b I want to boost I already have a set of eagle rods and arp stud 57 trim turbonetics. Shooting for 300whp do you guys think thes pistons would handle them ...also heard of b series vitara pistons but I can't find them

i always see JE pistons being used, I like wiseco as well. ls crank eagle rods aftermarket pistons and arp hardware should prep the motor for more of around 4-500hp I would think

 

RS is a cast piston. it will work at 300whp and if you aren't going to go higher, have a good tune and desire a long life it's a thought. the drawback to RS is the same as using stock pistons. they won't survive detonation and are easier to injure. the draw to cast is being able to use a .0010-.0020 piston to wall clearance which is considerably tighter than the .0025 absolute minimum you'll see with even the lowest expansion forged piston. tighter clearances mean no cold rattle and a longer ring and bore life

 

If your going to put all those goodies into that block, put slugs in and be done with it. SRP's work great and are a low expansion forged piston. Ive been running mine for 30k miles, car runs great 400whp all day long

 

Yeah my origional idea before I started thinking cheap was supertech forged

 

Vitaras are for single cams

 

Thats what i thoughthave but What are these

Those are npr pistons. I'm actually rebuilding my motor with them right now. Heard good things about them and the pistons and rings were only $150

 

Use a forged piston with a 4032 alloy as apposed to the fairly standard 2618. The only reason, I believe anyway, anyone would ever consider using a Safety/RS piston in a FI build would be to retain as much OE like reliability and longevity as possible. Thats something you can achieve with a 4032 alloy forged piston, without having to make the sacrifice of a weaker cast piston. Keep in mind, a lot of OE turbo and supercharged makes and models out there use 4032 alloy forged pistons and run forever, BMW, Chevrolet, Ford, Porsche, etc.

 

you mean the repackaged mahle pistons?

 

Supertech pistons are not Mahle pistons, nowhere close in fact. Supertech's pistons are made buy IASA, a forged piston manufaturer located in Argentina. The Supertech piston actually uses a Mahle 124 Alloy which is similar to the standard 4032 used by most piston manufacturers. Mahle 124 does have a few slight advantages over 4032, but I'm not really going to get into any of that. Mahle makes an awesome piston, when they want to. Their production stuff is decent, just not up to par with some of the higher end Mahle stuff I've gotten my hands on over the years. Supertech's pistons are nice, not the best out there, but not the worst either. I like them a lot for street NA use, actually. Its a good bang for buck NA piston.

 

Wow no way how can they sell repackaged mahle so cheap

 

Why are you installing after marker pistons to make 300hp?

 

you 100% on that? i've read everything from re packed powerpak pistons to iasa pistons with mahle forgings. the common net rumor is the same one over at evo world in this thread about mid way down?

http://forums.evolutionm.net/evo-eng...ns-before.html

which is the iasa made piston with a mahle forging

 

Mahle's forgings are proprietary, you cant just buy blank forgings from Mahle. Just like you can't buy blank forgings from JE, CP, etc. The poster in that thread seemed as if he didn't really understand what he himself was saying. He probably heard elsewhere that Supertech pistons were machined from forged Mahle 124 alloy forgings and made the assumption in his mind that it meant they were actually Mahle forgings. They aren't. They are Mahle 124 alloy forgings produced by IASA, and or, Supertech. The forgings are actually produced in Argentina as well. IASA and Supertech have nothing to do with Mahle, and vice versa.

You have to ask yourself a really simple question as well about this. Why would Willie buy a piston from Mahle and re-sell it at a net loss? It doesn't make any sense at all. Not to mention the forgings themselves that are the basis for Supertech pistons are different from the forgings that end up the Mahle Powerpak pistons.

Supertech pistons are Supertech pistons. They are Supertech forgings produced and machined for Supertech by IASA to the specifications provided by Supertech.

Thats it. Hopefully that clears up the mis-information out there.

Another example. RR58 is another popular alloy used for forged pistons as well. It's very similar to 2618, with some advanteges. It's more expensive than 2618. The RR stands for, "Rolls Royce." But any forgings made in RR58 by Accralite, Perfect Bore, etc belong to the companies who produce them. Not Rolls Royce.

 

ycp makes vitara pistons that most people use, i think they might have a b series version as well.

^^ What he said!!!


....but if you must. Just use ebay NPR LS pistons, fraction of the cost great for low boost an can handle your applications need.

 

Those are NPR pistons. Scroll down and read the page

 

i failed reading in school

 

Reason for forged is that I want t o be reliable while im beating it to or if I want to up the boost I can plus I already have eagle rods

 

you do realize that RS pistons are cast right?

if supertech is using mahle 124 alloy that would be a nice low cost choice. the one really nice benefit of 124 that i came across reading up is that it's less brittle than 4032 while being still low expansion.

 

bump

 

^^ why are you bumping this?

 

X2 lol..... im going to use the supertech 9:5 pistons and should spool up and perscion 5431 nicely im realy hoping for 350 + but setting a low goal
