If you're going that far why not buy pistons? You're really holding yourself back.

If you're going that far why not buy pistons? You're really holding yourself back.Yeah understand that but right now im in a pinch and need it done asap this is the most cost effective for me at the moment and most of this was pretty much handed to me. So do you think i should gap the rings.

My suggestion would be to at least see if the gap with all of the new rings installed is the same from piston to piston. Then cross reference your measurements with what is stated in the FSM.

Gap at the very end of stock spec

in my experience, stock pistons will fail at the ring lands. I got two weeks off my reused oem pistons, went supertech after that and ive been going strong for 3 years stock rods, t28 pushing 12psi. still I have been told many times that stock pistons can handle your setup and I dont doubt that. Why not go forged? its worth it.

If you're going KA-T upgrade your pistons and ring landings AT LEAST. I blew out my ringlandings on my first or second drift event after install.

Save yourself the downtime. Do some searches. People are always selling KA pistons.

I really didnt want to but ill be going over sized with the look of fhe cylinder wall on cylinder 3. Forged it is but i just dont justify almost a grand on parts and a re-tune.102482

The amount of money and quality of your work will affect the longevity of your build. I guessing you want your build to last. Spent the money. Get the right parts and tools.

You could pick up another good engine for the price of some nice pistons.

Thanks for your input guys Ive come to a conclusion and just part what I can and go sr which are more abundant here than the closest reliable ka which is 300 miles away.

Part of the game, unfortunately. I boosted my stock and super healthy KA(179psi across the board). Got it tuned conservatively and while it ran great for a month of daily driving, I blew the ringlands out the first event. I was only running 10psi on a 2871. Should have just gone with a forged bottom end to start because I would have saved money on parts alone, but now my $600 tune is rendered useless after only a month and I'll be spending almost the same amount to get it back on the dyno.

You're giving up? Pathetic. Take out a loan and sleeve that block. And stop coming up with excuses to cheap out and go another route. DO IT

I had a stock bore KA with wiseco pistons dropped in it last 3 years before the cylinders need to be bored out.

The $1,000 needed to make your ka last at 3-400whp is 1/2 of what you'll spend on an SR swap that stock vs stock is rated for the same HP internals wise.

I tried to destroy the first one I had, back in the day, as I was leaving for the military.

surely didn't spend $1000 nor was I able to successfully destroy the engine. just saying
