ross on big rods

[chrisAWD]

well, I talked to the machine shop about doing some work. I'll try to make this short and sweet. Basically they are not big fan of doing the 2g piston on big rods. And the main reason was cost. For $460 I can get a set of ross pistons with rings. The 2g's cost about $160 plus about $100 for the rings and $150 worth of machine work on the rods to fit em. total = $410. this seems like a no brainer to me to go with the ross then. my questions for you guys are as follows:

which rings does ross use with their pistons?(forgot to ask jack)

any weakness to these pistons versus the "stock" 2g units(ie long term durability etc.)

he said the ross's can be used in a press fit setup so they are ok.

is this a lopsided buildup? or are the 1g big rods and the ross's a good combo?

he really recomended going with the eagles to swing the ross's on but at another $350-400, i'm starting to get out of my range.(i had no intention of going to a fully built bottom end). And since I have a set of big rods already i'd like to use them.

i'll be running arp mains, rods, and headbolts in this setup fyi

Where did you find Ross pistons for $460? The best (in Canada) I've found is $575 US at Magnus Motorsports . They give you total seal rings and new pins with the Ross

I was considering big rods but I'm playin it safe and going with the Eagle H-Beams. It all depends on what you want to do

Well its always just a little more for something you know what I mean...
You have to set a line somewhere! Some will say you shoudl go with the eagles (such a popular combo) or some will say go with the 2G pistons. Personally I wanted at leist 8.5:1 and had my limits set on the prices. I was exactly where you are and opted for the big rods with the ross 9:1's. So far so good. I go the big rods new and has then shot peened and use total seal rings... I dont see myself ever making more than 450whp so no need for me to go with the eagles. It turned out in my case to only be like 30$ more for the ross's so why not eh =)

[chrisAWD]

you got 9:1 ross's? i'm looking at 8.5:1 for mine. how do you like the 9'1's?

 

[candela]

yes... and I like em just fine

 

[Talon007]

What is the most boost you have run?

 

[candela]

what does that have to do with anything?

 

[larryd]

Because theoretically you can run more boost on lower compression so my guess is he wants to know what amount of boost you have safely run on your 9:1 compression motor.

 

[Talon007]

Yep. Is there anyone running nitrous on either piston too? I'm considering nitrous in the future, just going to keep my options open.

 

[candela]

Well it doesnt really have anythign to do with me Larry because you know that what I run may be different to wha the runs. Turbo and everythign supporting it make it a different situation...

I am still breaking in the motor with the 14b, but have it at about 20psi right now. As soon as Im finished Ill put on my G50 and plan to run very similar numbers to what I ran before. ~18-19 on pump and as much as I can on c16 like ~26... I just dont see why this has much relelvance. I know "with all thigns equal more compression makes more power" and blah blah blah... but let it just be an upgrade to what your already doing. If need be just tune it better and run the same as you were before and you will make more power.

 

[Talon007]

Alright, I'm just curious, I'm new to the turbo engine. I plan to run a 20G at about 25psi on C16 at the track with supporting mods. Depending on what gas I'll run 15ish on the street.

 

[chrisAWD]

the price of 460 was from a local machine shop. turbotrix sells em for 485 with rings of course.

 

[chrisAWD]

after closer inspection I see that the prices I listed are for ross' street piston. the price you got from magnus is for their race piston. anyone know the difference between them.

 

[candela]

The Race Pistons utilisze file to fit rings and add a protective coating to guard against high boost and nitrous oxide. The Street Pistons are easier to install and are much stronger than stock.

[Talon007]

You get total seal rings from Magnus

 

[candela]

I got total seal from SBR

 

[Talon007]

I meant you get the total seal rings with the Race pistons for $575

Chris its dave You bout the block from me
I got my ross pistons from Showdownmotorsports for 400 bucks
www.showdownmotorsports.com It was 725 for the ross/eagle combo a really good deal. Check it out.
