4age build - Toyota Yaris Forums

ilikerice · 05-15-2014, 12:55 PM

Ok, I am having a hard time finding pistons for a 4age motor that is .5mm oversized. So I am looking for 81.5mm pistons. I am trying to stay less than $400 and the only thing I can find is $500+ for high compression or low compression pistons..

I am trying to stick to some stock pistons, but seems like they only thing available is High or Low comp. As for the build, I got it for free for helping with a swap in a MR2. I have no desire to keep this motor or put it in anything, and I hate to have a motor go to waste if someone else could use it. I don't expect to make a profit off it, and I don't want to lose money on it.

I already paid $450 for overbore .020, shaved head and block because of slight warpage, nothing crazy. Also hot tanked and cleaned up nicely.

I have already posted up on club4ag.com forum but that forums seems dead. If someone here knows people or can find a good deal on some decent pistons. Please link it here. Or PM me a phone number.

Thanks

A guy down here used Honda Pistons in his setup, if you're feeling up to the challenge you could try it as well.

Doesn't sound to me like OP is swapping into Yaris.

Here is a 4age swap documented to some degree http://microimageonline.com/forums/s...ad-(lotsa-pics)

Start at around page 13.

Yea, Ryze, I was looking at that also. Damn B-series pistons are soo cheap now-a-days. .. The only thing that is holding me back is the wrist pins fitting on the connecting rods. I guess I could buy them and if they don't fit, source out a B-series that needs to be rebuild after this one is done.. My budget is my credit card. Trying to keep it within that range as I pay it monthly.
