Have you thought of using the Hyundai G4JS pistons?
all of those part numbers are gone? i have oversized piston part numbers and 2 more std size part numbers for each piston
I did that once before as an experiement, but the CR was so high I couldnt run anything that didnt detonate like crazy. AND, the wristpins are a different size, 1mm different. I did realize then tho, that the valve reliefs dont have to match unless youre planning on redlining it. Did you ever try them?
i entered the GS piston part number at oemmitsubishiparts.com and they came up, maybe see if they can get them. i will talk to my dealer today
About 1660 of them.Quote:
Hey how many of these GSs did they make in 94?
How about using the G4JS rods with the G4JS pistons?Quote:
I think the 1G rod journals are wider and you would have to have them reduced but maybe only by a mm or 2. They take a wider bearing as well. Do you know anyone that retrofitted a 1g rod into a 2g setup?
The reason why you had so much knock with the high compression is because of the use of stock cams and 4G63 ecu. The ignition maps are too high and the stock cams increase the dynamic compression. There is only so much room allow to increase static compression and still run pump gas. The reason to increase static compression is not only to increase horsepower but to regain lost dynamic compression when using a bigger cam.
everything from the GS is completely obsolete and unavailable. the only parts still available are the rods. honestly go aftermarket or even go 96-98 64. and for rids, do the frankenstein setup. 1g rod bored out for the 22mm pin
The 10.5:1s are readily availablefrom wiseco and I wouldnt have to change anything at all, cept them of course! I have the 2.4 cams and head / intake already, 32k on the head that I have!
Wish you guys lived closer, would be cool to check out your car. There is a local guy that just got a 91 VR4, and has been calling me for help with it, the manual trans in it is shot, and I dont think he will ever find a new one, or someone that could fix it. And the the timing cover swelled and is rubbing on the belts.
the gs cylinder head assembly part number has been obsoleted too and is now the 2g head assembly as well just so you guys know
Here is a pic of the 2G head and intake / exhaust that Im switching to . Im starting to prep it. I have enough spare parts that I can pretty much assemble the entire assembly.I just have to have an o2 sensor port welded on the header.

I believe it's 96-98 Sonata.

If you are using that Sonata head, then your compression should be around 10:1. If you milled the head, you can reach 10.5:1.
