Well of course they are an upgrade....my point was JE's are ''super'' because a guy runs 20 PSI daily on them.

Anything forged IS an upgrade- for extra insurance..

108 grams would be between 25 and 30% less. Sorry, think not. Lightweight JE 2.5 pistons were in the mid 330 gm range.. The STD's were in the 360 gm range. The light weights were "peeling" the tops off in the mid 300 range with ANY deton ation. It was like running stock cast slugs.

2.2's have additional skirting... although JE has issues with this area, unless they fixed it.

WISECO'S all the way

Maybe I'm wrong? Either the pistons were 108 grams less or the rods were 108 less. I'll try to find out

No, I think they come with Sealed Power rings. Total Seal claims less than 2% leakdown for the life of the engine. I will test that out, lol!

With all this trash talk about JE's, I am freaking out!!!!!

The 2.2 je's are fine.. The skirts are a bit thin and prone to some collapsing, The 2.5's just don't get the lightweights (330 roughly grams... ) you need some meat there.

Like I said.. detonation on the JE's.. there go the tops...(lightweight), headlifting detonation with the wiseco's... eh.. put a new HG on

Simon, I ran gapless... The individual I bought the block from KNEW that went against mainstream TD thinking. He LAUGHED (all in fun) saying I would never tell anyone they were... I did.. That block could TAKE it. Lost it due to a comp cam S60 cam with stock valve springs (note to all DON"T do THAT!!!). Never had to change the valve seals (viton seals)... Never used a drop of oil... Damn, that set-up was FAST

I'm trying to picture what broke in that setup. did the mispatch of cams and springs make it drop a valve or something?

I got to agree with the Wiseco's, Ive been using them for a few years now and they have been very good to me, got em in a customers 5.0 on N2o and he buzzes the bajeepers out of that thing, can't believe how he tortures that thing, also used them in big block Mopes and I just never have problems with them. My machinest friend sugested them for my 2.2, I trust him , cause he builds natrional event winning super stock motors. If the Talon/ Mitsu guys are having problems with wiseco's its not the pistons fault!


P.S. and did I mention they are CHEEPER

How much boost can the weisco's hold before breaking? I was hoping to run 20-25 psi on them in my 89_shadow

Boost is not the issue it's detonation. Over 30 PSI can be run on stock cast pistons but if you run into the slightest bit of detonation say bye bye.

I have purchased a set of +40's a 255 intank fuel pump AFPR I am going to run 4mm oversized valves, and super 70 turbo, Along with 118 Octain Gas< at a minimum 118 octain. I bored the block .20got a cromally head gasket and A Large front mount Ic. Detination shouldnt be a problem HOWEVER this is always a chance it can happen whenever racing or driving
