Rebuild Time - Toyota Yaris Forums

Yoda · 02-09-2011, 02:58 PM

Ok so just wanna do upgraded rods and pistons for right now cause I low on funds. Found a builder that is local and full of experience. I just need to get the parts. My question is what size pistons and brand and also rods. Don't much about this stuff so I am doing my home work first.
Parmas hoping to get your input on this too since u have both.

O forgot to put in my goal. I want to shoot for 240whp and about the same in tq.

I got CP pistons. Get lower compression since your boosted.

Pauter or Crower rods. I got Pauter, took 6 weeks to get them. Maybe these days you can get rods faster. I had to notch my block for the rods.

Head studs -- I don't know if ARP makes them for our motors, they didn't when I got mine built. It's a good idea to do this as well and save your head gasket.

Bearings - going to use stock bearings?

So what happened?? Did U spin a rod/crank bearing. Or blow a hole through a piston.

This guy has rods, pistons and ring sets. https://www.raceeng.com/c-4028-engine-kits.aspx

@cali how low should i go in regards to comp? 9 or 9.5

@pimp didn't take it to the mech yet but i kno something is up. Sounds like marbles in a can. I was gonna rebuild it anyway but this happened sooner than expected. Thanks for the link gonna look around to see if i can get better prices on those.

@cdydjded thanks for the info see what answer you can get from them. O and why 75.5mm and not 75.0 mm? Just curious.

^ If he oversizes, he'll have to resleeve? That would be an added expense. (but the added displacement is nice).

ilikerice · 02-11-2011, 07:56 PM

sooooo... still gonna rebuild? i think since you got it ready to pull out just finish it.. hahahah.. u know.. for the sake of science

Bluevitz-rs · 02-12-2011, 12:22 AM

I say, if it ain't broke don't fix it. LOL

... I hope you realize that Yoda is an engineer lol.

As a fellow engineering student, my instinct says to add features until it is actually broken.

Ditto!!!
That stock motor is pretty tough. I would save your money for a quality Turbo. You have already found loose bolts from your trans. repair. Do you really what more strangers digging in your motor if it still running good?

Yoda · 02-12-2011, 02:40 PM

Yea gonna attach all the hoses back today, change oil and all that stuff. When this turbo goes I gonna get the Garret gt 255 I think it was called.

PETERPOOP · 02-12-2011, 02:52 PM

It's funny how you had to sell your old turbo kit back in the day because of lack of funds; now you got a turbo kit on and was about to do a built motor! hehe

Yoda · 02-12-2011, 05:47 PM

Yea I kno right. But hey that promotion gave me some flex room

Bluevitz-rs · 02-15-2011, 10:27 PM

So did you figure out what's making the noise yet?
