Hey whats up. I bought a set of .40 over type r pistons from RS a while back and was wondering if they were topline brand. is there anyway you can tell. i know they are not oem. are they topline brand? and if so anyone else use them

 

Topline makes pistons for honda.

OEM = Topline.

I dont think this is true.
From what i hear Topline is made by rock. OEM Honda pistons are made by Honda.

BTW- From everyone I know whos tried Topline, they are junk. The ring landings are infamous for breaking. Seriously dont waste your time or money

Im sorry, but you're wrong. Topline makes their own stuff, no over seas action here guy...I know for a fact.

I never said Topline is made over seas. From my knowledge they are the same brand or affiliated to Rock Pistons and or Hastings. Ive had a few friends use them with horrible results though

(acl,hastings,melling,topline,safety,enginetech,qu alcast,futur cylinder heads , Rol gaskets and couple other companies)

word, But I'm almost 100% certain that Topline doesn't produce the OEM pistons for Honda. I believe Honda has its own production facility for their motor parts.

I'll ask next time I talk to my buddy that works out there...

 

ok so whats the deal on topline pistons? Oh and how do you know if they are topline or not? my pistons just say p-73 on them and thats bout it!

 

topline

 

I put Topline pistons in Ron's daily driver Integra and they have been just fine. I have also used them in a couple of other builds, all without issues!

 

all the ones my friends have used where the ITR spec .20 over. In all the cases the rings all had blow-by. And when dissassembled the ring landings where allways broke on almost all the pistons

 

from what I experienced I had issues witht he skirts and the rings fitting right

but they are just a cheaper aftermarket OEM copy to me

 

This car had Topline ITR 81.50mm.

It ran pretty good. But other people I know had problems with oil consumption using the rings supplied with the pistons.

 

I concur, i wont ever use top line rings...I've never had a problem with OE rings.

 

is there a way you can tell that they are toplines?

 

Rs has there own line of cast pistons they are not top line ,rock or safty.

The top line and safty pistons come with a low tension oil ring so they do not work very well.
All of the pistons from RS come with a Good ring set you should not have a problem.

 

 

thanks for the info on the pistons. anyone have any experience with the RS cast pistons?

 

I've been running the topline pistons with rings for about a year. No problems yet, however my friend ran the same pistons and rings went bad after a couple of miles(professionally installed) . I would avoid them if at all possible, had i known back then i would've went with oem cast pistons or aftermarket pistons. good luck

 

i have bought prob 20 sets of topline pistons.

the PISTONS are not a problem IMO. i have never had issues. THE RINGS are USUALLY way too fat on the ring gap. I have had prob 13 sets that i bought new rings for, or had them send me .20 or .40 over rings to file down.

I would use their pistons, and ask them to send you oversized rings so you can filethem down, OR, you might get lucky and they will be ok.

but the piston itself, i have never had issues. BTW toplines shipping dept and warehouse is 30min from me, i have been there ,and SEEN WITH MY OWN eyes the shipping labels of pistons going to Honda/Acura dealerships

 

here is the website for anyone that needs it:

You will never get good ring seal by taking an oversized ring and filing it down to fit in a smaller bore. Rings are sold in particular sizes for a reason.

 

well, i kinda agree

 

i used topline STD JDM ITR pistons in my build.

about 4000 miles and strong as *****
