Hey guys im trying to finally decide on a piston/rod choice for my talon. I have narrowed it does to JE Pistons (9.0:1), Ross (9.0:1), or Arias (8.7:0), with Eagle H Beam rods. My budget is about 500-600 for pistons. What experiences does everyone have and what would you recommend?

i've talked with a dsm builder/expert about building a motor and what pistons should be used and what rods, he basically told me that you just cant go wrong with ross pistons
 
^^^ I agree I wouldnt use JE and havent heard about Arias so that would leave Ross for me but why not Wiseco. Wisecos are 8grams lighter then Ross I believe. Ross has less silcon base then wiseco so they tend to slap a lil more then Wiseco but if you plan to use nitrous I would choose the Ross. Either piston will do you fine, both have strong points, more of a personal prefrence between those two in my opinion.

I would go with Ross or Wiseco, secondley i wouldnt go with a compression any higher than 8:5:1 cuz then your tuning window is gonna be tiny and your not gonna get anywhere on pump gas...if this is gonna be a track car then 9:1 wouldnt be bad.
 
Thanks for all the responses so far guys, how about rods? My goal is a track car of 400-600 horses in the long run. Will the H beam rods be sufficient for such a goal?
 
Stay as far awar from JE as you can get.

Any of your other choices are nice. I prefer either Ross or Wiseco's, both are awesome.
 
Im curious too about the hate on JE's OMG) And what about H bean Eagle Rods? Are they well known for good performance? And what size bearings do they use? Standard or oversized? Sorry for all the noob questions guys i just love having info before i start anything
 
Supra boys are making 1200+hp on Eagle H beams. 2/3rd's of that is still more than anyone on here will make.

I chose Wiseco's for the weight, but I've heard great things about Ross too. JE's will have a slap issue if not properly clearanced.
 
1200 % 6 = 200...

So 200 hp per rod...


DSM at 200hp per rod = 800hp...

Just thought I'd make apples to apples eaiser....

Plenty of ordinary cars run 9:1. It's perfectly fine for a street car.
 
A gasoline fueled track car or pump gas record seeker is better off at 7.5-8:1 as this permits more boost....

35psi at 7.5:1 compression > 25psi at 8.5:1...

It's all about getting the right dynamic compression ratio for the fuel and the turbo that is bolted to its capabilities...


A street car with moderate boost 9:1 will have a slightly quicker spool... You will make more power at 10psi than 8.5:1 at 10psi for example... Compression = good up to the knock point.

Low compression + more boost = better when the total dynamic compression is equal...

It all depends on what fuel you want to run, spool and the boost level you can run.
 
Why the hate on JE's? Because 90% of the machine shops out there don't know how to clearance the block for them, it's not the machine shops fault, it's JE's for making the piston that way. As a result of that happening you tend to get ALOT more piston slap then with any other ordinary piston on the market that use the "regular" method of doing clearance on pistons, not JE's ####ed up way.
 
As far as the Eagle H Beam rods, how many have it installed? And using the factory crank, do you use the same bearing size as it originally came with or is it necessary to get different sized bearings?
 
Eagle rods are good. Yes you use the stock bearing size, as long as your crank hasn't been turned.

What's all this hate on JE's? My wife's been daily driving them for 3+ years without issue.

JE is a messed up firm. It took me 6 phone calls just to get the proper part # to order a set of rings.
 
is there a forged slug for n/t's? i see 9:1 CR's, but was told by craggar at slowboy, that they are for turbos. ne truth behind this?

i don't see any good reason why you could'nt use 9:1 forged turbo pistons on your n/t, it would work great..... :dsm:
 
i'm new to this engine building stuff myself! i'm gonna use pauter rods with je pistons for my 2.4! now is the brand of piston what's important or the level of machine work that is being done? i sure hope i didn't make a wrong choice, but i thought the choices for the 2.4 pistons were limited!
 
I went with wiseco 9:0.1 pistons on my stroker motor. reason for my choice is there ligther then ross pistons, ross cost 150 more, and wiseco has a good name many fast dsm and v8 buys use them. this lead me to trust there good.

For rods i went with oliver rods just because i love the design of them. reading there little book about the testing of the rod and how they designed it made me feel safe with them. they are also ligther then pauter rods.


9:0.1 pistons on the street is no problem. tuned right you will make more power at least boost then you could with any piston under that cr. if you plan on spraying your car and running lots of boost then go with a lower cr.

the only reason i questioned the fact was that i heard turbo piston rings were set differently than the n/t pistons. does ne one have pics of a turbo and n/t piston to compare, or can ne one confirm this from experience? i wouldnt see why the ring set location would matter, but it could.
 
Hey everyone, i finally purchased my bottom end set up today, i decided to go with Wiseco (8.2:1 CR) pistons with eagle H beam rods with ARP fasteners, with kings racing main/rod bearings. Thanks for everyones help with this decision.
