As the title says I'm looking for pistons to go in my 4G69 with 63 rods. I've done this once before towards a turbo build using CP pistons but CP doesn't work directly with the customer on custom applications. Problem is the company I previously used like many other speed shops doesn't exist anymore.
The reason I ask is I don't have the time to map out block with clay molds and the works so I need to find a company that is familiar with this build and order pistons thru them.
Any help is appreciated.

 

Weisco makes pistons for our car and the evo 8-9 rods are easily swapped.

Got any recent pics?

 

Thanx

 

would regular 63 stroker pistons work?

 

how big do they make the 4g63 stroker pistons? our cylinder bore is 87mm and a stock 4g63 is 85mm right? wouldnt you need a bigger piston?

 

The valve clearance would be the issue with the evo pistons even if they were 87mm.

 

That's why I'm looking for a company that has done this and has all the specs. Anyone can make a piston but I don't know all the clearances.

 

they're made for 100mm crank, i can't see why they'd be any different...didn't you have a set? what's the part number?

stroker pistons come in 87mm

 

Mine were customs and cp doesn't keep a record. They told me I had to use a third party.

 

Mine were made for the 4g69 through Weisco, not 87mm evo pistons. Part number , no sorry but it's here , even the direct link is posted a few times do a little searching.

 

LMAO sorry I worked 14 hours yesterday my brain was a bit foggy when I posted. I was thinking of how much the 4g63 can be overbored and I could remember the numbers (.04, .08) but I was thinking of those numbers as mm not inches. so the numbers just werent matching up in my head. lol yea your right. :P Brain fart.

 

I really hate those search it answers. But your post was half helpful.
I did search obviously with no luck since I posted my own thread. I may not have spent hours searching but I did try. If you don't mind I'd love to see one of those links, I certainly can't find it.

 

Well you never post up

I searched here....

The 4g69 info is on the 20th red row , so post up a few pics

 

I appreciate that. I saw the wiesco page but must have overlooked ours. But the next problem is that the Evo rod is 0.050" shorter so the comp is way off and something strange had to be done with the wrist pin location due to that aswell. But I'll email them and see what they say. Thanx for that.
Ill post pics when I have some. I'm horrible at taking them.

 

I have seen the evo rods in the eclipse forum work both stock and aftermarket . Look at club4g.org
