Guest Mike Posted October 5, 2006 Share Posted October 5, 2006 My pistons have part number 02-228-08-B stamped on top. Can anyone tell me what brand uses this numbering scheme? Yes, this is a redundant post but I've revise the question and the "Title" for refined response. Quote Link to comment Share on other sites More sharing options...
jbk240z Posted October 6, 2006 Share Posted October 6, 2006 I've been looking, but no info yet.............any other markings on the piston? Quote Link to comment Share on other sites More sharing options...
Guest Mike Posted October 6, 2006 Share Posted October 6, 2006 I can only see the tops of the pistons. I had to remove the heads to have them milled. I overheated them last weekend because I couldn't stop driving since I had my 82-year-old mother with me and she can't take the heat due to heart problems. Anyway... that's all the info I have. Don't go out of your way jbk240z... I was just hoping someone would recognize the numeric parts scheme. If these are forged pistons, I want to add 100HP nitrous:flamedevi If they're cast, I can't do that:( Quote Link to comment Share on other sites More sharing options...
Guest zfan Posted October 7, 2006 Share Posted October 7, 2006 If they are cast you can still add a small shot say 75-100. You just need to be extra careful! Mike Quote Link to comment Share on other sites More sharing options...
dustin280zx Posted October 7, 2006 Share Posted October 7, 2006 you can run a 100...just make sure it dont pre detonate or go lean. retard timing and run race gas through your nitrous system...or put a mix of race gas and 93 depending on your c/r. You can buy trw's for pretty cheap....like around 300 on ebay i think if you put a hole through one of yours. I also looked on the net for an hour between my classes and i didnt find anything on for the part number you gave...if you really want to find out you'll have the pull the piston out and look at it...i think theres info on the inside of the skirt if i'm not mistaken.

jbk240z Posted October 7, 2006 Share Posted October 7, 2006 You could pull the oil pan, and use one of those little telescoping inspection mirrors to look at the underside of the pistons. Just a thought. I am interested in finding out what the pistons are, sorta like a challenging puzzle. Quote Link to comment Share on other sites More sharing options...
Guest Mike Posted October 7, 2006 Share Posted October 7, 2006 I've always been told that running any amount of NOS with cast pistons is very risky. But what the heck... I'll just make sure to squirt plenty of fuel when I spray the NOS. IDEA: I've been toying with the idea adding a small secondary fuel tank with a 70/30 mix of 93 octane with this stuff... http://www.kemcooil.com/product_info.php?pId=61 for the added fuel needed when I spray the NOS. This SAVES $$$ by eliminating the need to run a full tank of race fuel. It should be easy to jump the overall octane rating to whatever I want... say 110 or so but only when spraying NOS (a stronger mix may be needed for 110). But again, I can run 93 pump gas most of the time. What do you guys think? For safety, I could add a level detector in the small tank that shuts down NOS if the secondary fuel is running low.

Guest Mike Posted October 7, 2006 Share Posted October 7, 2006 JBK240Z That's a great idea. I might give that a try!! Quote Link to comment Share on other sites More sharing options...
dustin280zx Posted October 7, 2006 Share Posted October 7, 2006 i would get a one gallon fuel cell and seperate fuel system for your nitrous. that would be the right way and just use c14 in the fuel cell. i dont know if i would use that octane booster. it doesnt say if it is motor octane or not either.

Guest Mike Posted October 7, 2006 Share Posted October 7, 2006 Dustin That's what I was thinking... a dedicated fuel cell filled with insanely high octane to spray along with the NOS. Please explain what you mean regarding "motor octane" vs "ether". The stuff has tetraethyl lead and can boost the heck out your octane rating... so they say. i would get a one gallon fuel cell and seperate fuel system for your nitrous. that would be the right way and just use c14 in the fuel cell. i dont know if i would use that octane booster. it doesnt say if it is motor octane or not either.

dustin280zx Posted October 7, 2006 Share Posted October 7, 2006 here yeah go... http://www.bartelby.net/65/oc/octanenu.html that should sum it up pretty good. vp uses motor octane rating. Quote Link to comment Share on other sites More sharing options...
Guest Mike Posted October 7, 2006 Share Posted October 7, 2006 dustin Below is a cut/paste of their octane claims. Perhaps you can decipher the data and tell me... TREAT RATES R+M/2 0.6- Ounces OS-130 to 1 gallon / fuel……2.0 point octane increase 1.2- Ounces OS-130 to 1 gallon / fuel……3.5 point octane increase 1.8- Ounces OS-130 to 1 gallon / fuel……5.0 point octane increase 2.4- Ounces OS-130 to 1 gallon / fuel……6.5 point octane increase 3.0- Ounces OS-130 to 1 gallon / fuel……8.0 point octane increase 6.0- Ounces OS-130 to 1 gallon / fuel……11.0 point octane increase 18- Ounces OS-130 to 1 gallon / fuel……16.0 point octane increase EXAMPLE: 18 ounces added to 10 gallons of fuel will turn a 93 octane into a 98 octane, 30 ounces into a 101 octane, etc. Guaranteed!

dustin280zx Posted October 8, 2006 Share Posted October 8, 2006 .6 oz- 93 octane+2 = 95 octane 1.2 oz- 93 octane+96.5 1.8- 93 octane+100 and so on weather the new octane is motor you'll have to research it or contact the company. vp also sells an octane booster http://www.vpracingfuels.com/vp_03_chemicals.html Quote Link to comment Share on other sites More sharing options...
Guest Mike Posted October 8, 2006 Share Posted October 8, 2006 OS-130 contains tetraethyl lead, which boosts octane more than anything, from what I understand. I'll contact the company with your query. Quote Link to comment Share on other sites More sharing options...
Guest Mike Posted October 9, 2006 Share Posted October 9, 2006 After more cleaning, I found a second number... H345NP .060 These are Sealed Power hypereutectic .60 over. Thanks everyone. Quote Link to comment Share on other sites More sharing options...
jbk240z Posted October 10, 2006 Share Posted October 10, 2006 I'm glad you fogured it out. Those are pretty good pistons IMO. Add a 150 shot kit and tune properly and you should be fine. Good luck. Quote Link to comment Share on other sites More sharing options...
dustin280zx Posted October 10, 2006 Share Posted October 10, 2006 glad you figured it out...have fun throwing the juice to it. Quote Link to comment Share on other sites More sharing options...
Guest Mike Posted October 10, 2006 Share Posted October 10, 2006 I'm afraid to add more than 50HP of N2O with cast pistons. Am I just being a wuss? If I spray enough alcohol/H2O will that prevent melted pistons? Quote Link to comment Share on other sites More sharing options...
dustin280zx Posted October 11, 2006 Share Posted October 11, 2006 your trying to over complicate things...all you need to do is make sure you have good fuel and take some timing out. theres guys run hypereutectic pistons that run 400 shot of nitrous. the only thing that kills pistons is detination. just ask any turbo guy its the same way. boost dont kill pistons...detination does. just start out with a 100 shot...check the plugs and go from there. and if you do flub up you can get a used set of forged on ebay for cheap.

Guest Mike Posted October 11, 2006 Share Posted October 11, 2006 DUSTIN... It's in my nature to complicate things. I just can't help myself. It's like an addiction. I NEED complication. I MUST HAVE MY FIX of complication or I get the shakes:shock: Seriously... what's the big deal about forged pistons if they don't hold up significantly better? If I don't need them, why would I spend the $$$ Quote Link to comment Share on other sites More sharing options...
