Your best bet would be to replace it with a JDM engine.

If you are going to pull the engine apart to replace piston rings than you may as well replace main/crank/rod bearings, headgasket, valve stem seals ect. Basically a full rebuild.

So yea you are better off buying a JDM 4g63 if you can find a good one. Search "used jap" on 411.ca for a bunch of import shops that can supply and install engines/parts.

I guess my first question would be how do you know it needs rings? Not to be a sarcastic *****..

If you say a compression test and the numbers weren't all the same it could be casued by a valve seat, seal etc.

SuprAdam

99% of the time if compression is low in one cylinder it will be rings. I cant see worn valve stem seals showing up on a compression test. If it is low in all cylinders, headgasket.

You can also check for blowby, with the engine on remove the oil cap and look for vapour. Look at the exhaust while the car is on, blue smoke is oil.

OK well ill looking into a jdm engine ...thanks guy and i know its the rings because we had ti checked out in a local shop..but you never know thanks for all the advice guys and ill keep you updated

Or you could just buy a wideband O2 controller and a fuel controller for $600 or less and tune your car yourself whenever you want, however you want. There is no way in hell I would trust a shop to tune my car, especially if I couldn't monitor it.

Slight change in weather could drastically throw off your AFR's and cause you to melt a piston, depending how aggressively they make the tune.

i wouldn't reccomend getting a jdm motor, get it rebuilt instead, that way u will know it will have perfect compression

mcd

i would also recommend rebuilding it, i bought a jdm used talon engine and it blew couple months later, didnt seem right from the start

jdmsteR

are jdm engines as prone to crankwalk as the usdm ones? or are they a better choice to go with? these motors dont seem like they can go 50k kms without something blowing ..

try toronto dsm board

Most talons go up to 300k, some up to 400k. Its just everyone beats the crap out of them and expects them to last.

You can try the dealership

MRDSM

If your interested in getting it rebuilt i have an excellent dsm engine specialist that is local and is fair in pricing, built my race motor and many of my customers as well.
