datz280 Posted May 15, 2008 Share Posted May 15, 2008 I just got a quote from Summit Racing for a set of forged pistons with pins and rings $902.00!!! I was shocked. After searching the forums it looked like a little over a year ago they were around 600. I am going to call and ask for a quote on a set of stock 83 N/A pistons (no dish) and see what I get. If it is still near the one grand mark I am going to look at ITM cast pistons ($275). This leads me to my question. I understand that forged will take some more detonation, but how much more? If the price of forged is prohibited how much of a cost benefit tradeoff will I have with cast. I plan on in the future running a Holset, intercoller, and ~14psi.

NCchris Posted May 15, 2008 Share Posted May 15, 2008 I had the same sticker shock with Ross. Haven't bought anything yet. fyi http://forums.hybridz.org/showthread.php?t=133455 Quote Link to comment Share on other sites More sharing options...

Dragonfly Posted May 15, 2008 Share Posted May 15, 2008 I can't answer your question for you but I can tell you that my Arias forged pistons with rings, full floating pins and wire locks cost $800+ and that was several years ago. Mine were also lightened and weight matched by Arias after being made to my specs, so you might want to give them a call prior to paying for just "forged" if you know what I mean. I can also tell you that if you are concerned with balance and weight (which you should be about balance at least) the forged ones get another mark on the "pros" side of the list.

jasper Posted May 15, 2008 Share Posted May 15, 2008 A stock piston for my Mercedes 190E 2.6 was $300.00 . I bought a used engine for $1000.00 Quote Link to comment Share on other sites More sharing options...
TrumpetRhapsody Posted May 15, 2008 Share Posted May 15, 2008 Is that deal not going on anymore for $600 through... can't remember now. Quote Link to comment Share on other sites More sharing options...
jeffer949 Posted May 15, 2008 Share Posted May 15, 2008 You dont need forged pistions with a holset and 14psi. Im runing it right now Im saving up for a set right now but im looking for way more than 14psi. Im just running this engine till i can build a nice one. Bigphil is running like 26psi on a stock motor and head with meth injection. So if thats as high of boost as you plan on running. i personally would save the money..

If it is still near the one grand mark I am going to look at ITM cast pistons ($275). Did you ask for a set of forged pistons for an L28 or did you ask for a custom set of pistons with all the specs you want. Not too long ago you could get "custom" pistons from Summit with retainers and wrist pins for under $500. I'd be pretty shocked if the price had doubled. I'm guessing you said "Nissan" instead of "custom". Quote Link to comment Share on other sites More sharing options...
datz280 Posted May 15, 2008 Author Share Posted May 15, 2008 when I ordered the set I filled out a Ross spec sheet with all of the measurements and asked for a custom set of 6. I told the guy at Summit that 902 was quite a lot and I had recalled a price more in the 600 range. He told me that was the price for a custom set. Thats why I thought if I asked for a stock +1 mm 83 N/A flattop it would be cheaper. I'm still unsure on the forged vs cast issue but the savings would afford me MSnS and some other goodies.

1 fast z Posted May 16, 2008 Share Posted May 16, 2008 I buy mine from venolia for 55.00 a peice, for basicly a 240sx forged unit. Quote Link to comment Share on other sites More sharing options...
aarang Posted May 16, 2008 Share Posted May 16, 2008 Yeah, I got the Ross pistons through Summit back in 2003/2004 for $463.00 with rings and pins. They do have Datsun specs on file for flat top and dished. I would go with some of they're spec files instead of full custom as it will lower the price. I'm sure the price has gone up some in four years, though. Quote Link to comment Share on other sites More sharing options...

rvandivort Posted May 18, 2008 Share Posted May 18, 2008 The stock Datsun/Nissan ones are just fine! Don`t get too greedy! Rods are cool,pistons are cool! Nissan has done a beautiful thing with the engine.It was a racing car to begin with.And ,how lucky are We for this! Quote Link to comment Share on other sites More sharing options...
TrumpetRhapsody Posted May 18, 2008 Share Posted May 18, 2008 True, but the problem arises when you want to increase bore (no longer stock piston size), stroke it (different pin height), and keep dishes for high boost ($$$). Quote Link to comment Share on other sites More sharing options...
rvandivort Posted May 18, 2008 Share Posted May 18, 2008 And..let Me tell You something else!! I ran My 76 for over 200 miles at 280f. I had to refill the radiator. Took My radiator in to the shop..The guy(he`s been around for a while) said this thing should have blown!! The bottom part was totally blocked. The compression readings at 306k were 150,150,150,150,150, 140. Quote Link to comment Share on other sites More sharing options...
rvandivort Posted May 18, 2008 Share Posted May 18, 2008 Well, I didn`t get the dishes part, But the point is that this car is really cool and bore size and pin height are irrelevant anyway. It has a great capacity for performance. Just boost the SOB! Quote Link to comment Share on other sites More sharing options...
