greg_banshee Posted February 7, 2006 Report Share Posted February 7, 2006 (edited) ya i'm actually going to do a rebuild and bore it out probley only 1 over and ppl r telling to get Wiseco kit ... i would but if PRO-X is as good as they say they are and reliable as stock if not more reliable then hell thats what i want i'd sacrifice the extra few HP for that. cause i really don't wana do another rebuild every year or every 2 years even .. i will if i have to but if i don't have to i won't. my 99 is on stock bore and only had a ring job 3 years ago and it had 115-120lb's a side before the summer last year, but i feel bad them pistons are gona let lose anytime now so Are the POR-X pistons really more reliable ?

Gargamel Posted February 7, 2006 Report Share Posted February 7, 2006 don't know about the POR-X but if the stockers lasted you that long the Wiseco will last the same time span if not a little more. I only do a top end like every 3~4 years granted I ride only in the spring through fall months but I ride every weekend when I can, and I use Wiseco. Hope that helps you Quote Link to comment Share on other sites More sharing options...
locogato11283 Posted February 7, 2006 Report Share Posted February 7, 2006 wiseco...put pro junk in my bros old banshee..that shit didnt last long. never had any issues with wiseco.. Quote Link to comment Share on other sites More sharing options...
banshee tuner Posted February 7, 2006 Report Share Posted February 7, 2006 Don't have any experience with pro-x but wiseco is a good piston. Quote Link to comment Share on other sites More sharing options...

shanYE west Posted February 7, 2006 Report Share Posted February 7, 2006 I had wiseco in my banshee for 6 months and when I put my national kit in I swithced to PRO-X . The wiseco piston was in pretty ruff shape with a couple of cold seize spots on the pistons. I was always pretty adamant about warm ups and stuff like that. I just took out my PRO-X pistons 3 years later and the pistons are in perfect shape, and I didn't do anything different that I didn't do with the wiseco's. So from my experience the PRO-X pistons by far exceeds the reliablity of the wiseco. I've known a few people that used wiseco's and didn't have any luck with them either. So from what I've seen I prefer the cast piston over the forged. Quote Link to comment Share on other sites More sharing options...
Polish Posted February 7, 2006 Report Share Posted February 7, 2006 what is PRO - X? use WEISCO Quote Link to comment Share on other sites More sharing options...
sandman4free Posted February 7, 2006 Report Share Posted February 7, 2006 pro-x is the same as OEM just under a diffrent name. I only use pro-x pistons and never had a problem. Quote Link to comment Share on other sites More sharing options...

s-540 Posted February 8, 2006 Report Share Posted February 8, 2006 (edited) forged pistons are stronger than cast. but you need to let forge piston warm up before you go to W.O.T. . cast piston do not expand like the forge pistons so you can start up and take off with out the piston needing to expand in the bore.

FASTOYS Posted February 9, 2006 Report Share Posted February 9, 2006 I have had good luck with both when used correctly. The ProX cast pistons dont live as long in a built Banshee that is high hp/high rev often and we have seen them break with to much rpm! The Wiseco's hold up very well to high hp and almost every good engine builder uses them. You will have to have more piston to cyl. clearance to run the Wiseco forged pistons than a cast piston but not much. That is my .02.

greg_banshee Posted February 9, 2006 Author Report Share Posted February 9, 2006 i saw a pic of your banshee i dirt wheels 470613[/snapback] Thanx for the info ! ya i think i'll go with the Wiesco Kit. my Shee hasn't been in dirt wheels yet, i hope it is soon tho ! lol Quote Link to comment Share on other sites More sharing options...
Shee-Male Posted February 9, 2006 Report Share Posted February 9, 2006 Forged pistons are a better piston period, if you had "cold seizing" spots on them that probably because the cylinders were not sized properly, forged pistons require more clearance than cast, and all pistons are not exactly the same size, before the jugs can be honed to there finished size the pistons have to be checked with a micrometer then add the clearence. Engines with certin upgrades will require more clearance. .003-.004 clearence is where you want to be. Cast pistons can break apart or shatter, forged won't. Wiseco has also been around a very long time and used in countless applications, they have done their reserch, and I rest easy knowing I got wiseco's in my shee!

I only use wiseco in mine, and other than the problems I ALWAYS had with my 87, they are a good choice. Quote Link to comment Share on other sites More sharing options...
RNBRAD Posted February 9, 2006 Report Share Posted February 9, 2006 I've used Pro-X and Wiseco. I've had better luck with pro-x over the years but doesn't mean Wiseco is a bad piston. For higher horspower/compression motors that can be hard to tune and prone to detonation definitly Wiseco. Cast pistons will provide a better seal and less friction with less bore wear. In motors that can run cast, this is a better benefit. So when someone says that a forged pistons is a better piston than a cast, they really need to read this article.
