what kind of power figures are we looking at, with a 01 itr with mugen header, exhaust, carsound cat, ATS final, toda flywheel, and exedy clutch (oh yeah drop in filter)

With these pistons and jun 3's and a tuned ECU, what type of power at the wheels are we looking at




12.5:1 compression ratio, JUN/Cosworth pistons

210whp

 

thats an expensive set of pistons.

 

not really 600.00 is not bad for JUN cosworth quality

 

I'm confused....those are JUN's or Cosworth's or are they the same thing. JUN makes those or Cosworth makes those?

 

I believe Cosworth makes pistons for Jun.

I've heard of this from a retailer of JUn prods, cool guy but he didn't want to tell me the company that makes them. He told me all I would be doing is paying for there name, but that's it no mo details. I would mind getting me a set.

Would I have to make any mods other then valve train mods to accomdate these pistions?? I'm really thinking of getting them

can I run pump gas with 12.5:1 compression?

I read somewhere that Cosworth makes JUN pistons. I believe they're made in England. Not sure though. They look sweet..

 

Cheap Bastard, are you running aftermarket HC pistons with your JUN III setup?

 

Holy Compression Ratio, Batman! Is 12.5:1 even streetable with shitty SoCal Petrol (91 r+m/2)?

Is there anything one can do to the head that reduces CR? Opening up comustion chambers or the like?

 

I get 94 here in NJ (hell yeah sunoco), is that high enough

 

With those pistons, you would end up with a set-up requiering very good tuning. You should not have to modify the valve train because of the pistons but because of the more aggressive camshafts.
12.5 CR is getting border line to run pump gas IMO.
From what I have seen of the Jun camshafts, I would think you'll get around 215 WHP

 

Not without a few noises! I think 11.5 is as high as you should take it here in SoCal.

 

I'm in NJ with 94 octane gas readly available what do you think???

 

You should remove the link in your first post if you're really interested in them.

Someone may beat you to the punch.

 

12.5 is probably okay with 94 ocatane again you should probably ask someone whose done that, i dont know anyone that has that high compression so i cant answer from experiance.

 

Those pistons are low compression and VERY OVERPRICED.

 

the pistons are $600

 

hey fooo!!!!
its basically the same setup I have in my car you heard it man the switchover the idle
Im running the 12.5s but the Jun/Cosworths I think are slightly lower judgeing by the fact that the dome isnt a point like mine are
get them you wont regret it
and itll work with Jun3s
designed as a package
you will need valvesprings and retainers for the cams tho
and an ECU to make it run **** and ***
and if u get a Jun proggy you wont have the wonderful vtec flutter
that every other proggy gives at switchover
I love my setup
and it pulls mad but cant wait to dyno

 

the dome kinda looks like toda

 

OMG--hooptie, sorry if I sound like an *** but--You jacked my avatar!

 

Do you mean that 12.5:1 CR is not considered "high compression" or do you mean that these pistons do not raise compression to 12.5:1 ?

 

those pistons arent 12.5:1
more like 11.5 or less.

 

I am running stock bottom.
