I looking for 11.5 to 12.0 cr pistons to use it with nitros in my new engine.

what is the best pistons so i can go with?
1. CP
2. Wiseco
3. JE

my spec is:

B20 84mm stock sleeve
eagle H beam rod
Golden eagle guard
p30 head
pw0 cams
JG cam sprocket
JDM pw0 dual valve spring INT & EXH
H22 345cc injectors
DIY ITB's (4agz TB's)
chipped JDM P08
Tunned with crome (By me)

 

To be honest you really can't go wrong with any of those manuf. That is the truth, I have used both JE and CP pistons with great results. Wiseco offers a good piston as well and is used my quite a few engine builders. I believe people will agree with me. It's user preference as well as which manuf. offers what compression ratio and bore as stock shelf.

CP has a piston that will work perfect for you, part#7117 which will drop into a 84mm bore no problem, or if you have a 84.5 you can use part#7118.

I would like to try Wiseco in the future, I like the fact they coat the skirt of the pistons, and they yielded pretty good results from a test that Jeff@Importbuildsers did, but who is to say that test was accurate. None the less, I'd give them a shot. They have a piston made for a b20 with a p30 head.

84mm Part#K567M84
84.5mm Part#K567M845

 

thanks for your usefull replay.

what is the max shot you think i can go with my setup?

i am going to use direct port four fogger.

 

That's a pretty broad question. It all comes down to your fuel system and just the way your car is setup. Probably need to upgade your pump and a few other things to really push those higher shots. The most I have ran is a 75 shot.

 

any more replay?

 

You can destroy any piston with a shitty tune or an unusual/unforseen issue. You can also make 600whp on any of those w/o issues. I've seen that CP are the most 'perfect' piston (tolerances), but also that they burn their valve releifs if you get oil in the chamber. JE/Wiseco/Arias all seem to have their good & bad stories, but it usually comes down to the fact they are just forged aluminum alloy, which isn't a wonder metal. If I ever have a motor problem, I'd rather the pistons go before the valves, sleeves, bearings, timing belts/gears - so I don't want a wonder metal in there.

 

I have had experience, either in my own engine or cars I have tuned, with JE, Wiseco, ENDYN, CP, SRP and Ross. All of the pistons withstanded a good amount of abuse. I run CP's in my current engine

 

anybody run srp's?

 

We have had nothing but great success with Arias Pistons.

Love mine went with Arais after my Valve Reliefs took a shat on me w/ my CP's..... But with all respect when these pistons are failing 9 times out of 10 it isnt the piston that go bad it was some sort of detonation that causes the damage....

 

CP every builder i talked to recommends so.....id say CP.

 

JE, Aries, CP, Wiseco

pick one they are all very good pistons.

I have for the last 3 years. Great piston for the price.

 

I've used all three with no problem.
cp is the shiniest
wiseco is well balanced each piston to pin
JE ?
out all I had no problem

I didn't know how shiny a piston is was a measure of quality now.

 

endyn &gt; * for the simple fact of the time and engineering that goes ito each set for the price.

did I say the shininest of it makes it great quality? it was simply mocking people like you. they are all the same materials just different styles. and I noticed a lot of people here love CP, so I figured it was because they are shiney
I used JE in my first build. they were in a package deal
wiseco in my second build. they were cheapest at the time
and Cp in my current. they were on sale

all them went through a lot and never broke

in actuality the best company out there is ARIAS, my next project will have them

 

they're probably not the best, but i like the Mahle pistons. and good for a budget. i was running 11.7 in a b16 on a 125 shot. made 281/220 to the wheels. they're quiet, all sets i have seen are incrediblt close tolerences when manu'd. they're under 400 with rings

 

CP's

i did in my first b16, i think they should have held up a little better than they did, but it was fun learning. they are a great price as an entry level forged piston also.

my current b16 has JE in it.

my gsr that i am in the process of building right now will be getting CP's. the last 2 engines that i have built for friends have been abused and standing up well on the CP's.

as stated above, all are good. it is all in the tune up.

p.s. i dont know the truth behind this, but was told by my supplier that once a piston is made with a tool from CP, a new tool is used for each new piston, so with that i can see how a shinny piston could be said. he hee.
