Im gettin ready to run a t3/t4 57trim on my gsr with a built motor. Ive got my rods picked out and i plan on running serious boost at the track, but im not sure what pistons to run. I know i want to run 9.0:1 compression but ive heard there have been problems with JE pistons as of recent. What are yall opinions on pistons. Im lookin at Arias, JE, SRP, and Wiesco.

 

why not some CP's ?

 

what kind of problems with the 9:1 compression JE pistons have you heard of? i just bought some last week along with eagle rods. i wasnt aware of any problems.

I hear they are very nice pistons...heres a pic of mine.

 

I heared from race engineering that as of recently JE pistons were havin problems after 15 psi of boost, the rings were messin up. Anyone else hear this...

 

JE pistons are very good. shouldn't have any problems with those. We've been running custom ross pistons recently with great results

 

I would say CP or Endyn.

Sounds like more BS to discredit a very good company that makes very good pistons. Stop spreading mis-information. If you have not the experienced yourself then it probably didn't happened. Unless you've got pictures, but then it was probably a crappy tune. BTW ENDYN uses custom JE pistons... Just food for thought. CP's are nice though.

 

why not some JEs

Im not spreading mis-information, I was asking if others had heard this, I heard it from Race Engineering, a reputable company that sells JE, thats why I asked. What would I gain by discrediting a company like JE....

I've never had a problem with JE's.

The problem is not correctly gapping the rings for turbo applications or improper piston to wall clearance.

I have used JE and Arias pistons. Both are great! Ross pistons are good too .

 

I think they were talking about SRP pistons, which are a brand of JE pistons. SRP's are a high silicone forging and don't take too kindly to a lot of boost. IMHO, any of the big name piston makers are great (JE, Arias, CP, Wiseco, Ross, Diamond, etc)
